Snapshot 58 No.580-589
589. An old career

A part of 500 kV Bousou line of Tokyo Power.
Totally 110 pylons of this size connects the substations at Siroi and Itihara.
The tower in the center is Nr. 38th from the Siroi side.
The reason I put here this nondescript photo is that my old career always makes me look at these installation. Something similar to those in the radio field who tend to look at antennas wherever they go.
For example, medical doctors, when first meet a person, are said to observe, first of all, his or her complexion. This is a natural behavior as the face is the first-hand barometer of the health condition.
This doctors' attitude or habit will persist even after they are retired.
Probably the best is to forget completely the old occupation and to indulge in the world of
ka-chou-fuu-getu / hana-tori-kaze-tuki (flower-bird-wind-moon). This however is quite difficult to achieve.
588. Yuri-no-ki
The time of
yuri-no-ki's flowers has come.
Tried to find them at a nearby square.
Taking a closer look is needed. As in the photo they are blossoming this year too.
587. Gas pipeline bridge

A name plate of a nearby gas bridge of Tokyo Gas.
Checked this bridge for comparison with that of Kanto Natural Gas Development listed here before.

Only a deformed rebar is attached.
The previuos one stands at a place, nothing around. While this is inside a riverside control facility equipped with a lightning rod on top of a high mast.
586. A leaf of kasiwa

A leaf wrapping a
kasiwa-moti.
The captivating shape made me take this shot.
The
kasiwa's leaves, at this time of year, don't grow to this size yet. I wonder if the leaves of last year are preserved and used now.
I heard that these days there are artificial leaves made from paper or prastics. So I tore it up. It gave me a feeling of a raw leaf.
However, a technique mimicing even such raw feeling might be applied. Well, either is OK, for this case too.
585. Sakanao water gate

The Sakanao water gate connecting Tone-river and Inba-marsh. Seen from the marsh side.
It keeps the marsh's water level about 1.5 m above that of the Tone-river.
This necessitates a fish passage and a lock gate.
About 50 cm-wide fish ladders are installed at both ends of the gate. As the water is made to flow constantly, fishes like
funa, koi, unagi (eel) can move in and out.
The area with a gate open upward at the right of the photo is that lock. A boat of the size for a 2-seat bass-fishing can easily pass there.
When passing through the lock, only thing to have to do is just pulling a dedicated cord. It enables all processes of gate opening/closing, water filling/draining being done automatically.

This is from the Water Agency website.
Indicating the water levels of the Tokyo Bay, Inba Marsh and Tone River.
584. U no me

? ?
The captioned
u no me might be confused with such word as
uo no me (a foot corn? not sure).
Borrowing Chinese characters looks a must. "U" "NO" "ME". Like something greatly deformed 👁, of 🦆 (cormorant's eyes).
I happened to encounter a relaxed cormorant at the usual bicycle lane along the Sin-river. Wanting to see again its green eyes, once being taken up here, I tried to look into them through the camera finder. This is that shot.
U mmm. Green, surely.
583. Kusu-otiba

It is said that "
kusu-otiba" or "
tokiwagi-otiba" is the
kigo*1 of the early summer.
The photo shows
kusunoki at a nearby street.
A large amount of leaves fall, seemingly giving their seats to the young ones.
"Being alive" is said to be a continuation of constant renewal.
Evergreen trees at this time of year show us this process vividly.
*1 Haiku seasonal key word
582. A renewal after 40 years / Nr. 2

The 40 years bring this once a newly-built town to the time to have to renew various things.
Things like this
kusu look to be no exception. In the same street, works to renew running-water pipes are going on.
581. A renewal after 40 years

The photo shows a recently renewed substation for the lightweight railway at our place.
The trains are operated for 40 years, I believe, and its substation equipment had aged and was replaced this time.
It receives power at 6.6 kV and feeds DC 750 V, a half voltage for ordinary railway, to the trains. The foward is the DC control panel.

This shows the train. which is very popular among children.
A train consists of 3 cars, and 3 trains exist. The max. speed is 50 km/h. NIPPON SHARYO make.
The front and rear cars have 150 kW motor each, 300 kW for a train. Thus the current at the train start is to be 400 A.
580.@Donguri flowers

At this time of year, trees that bear
donguri (acorns) have flowers too.
Those like dangling strings in the early spring are their flowers.
The photo shows the flowers of
kunugi I saw close to my place. These are male flowers which are putting out pollens now.
While the female flowers are not so eye-catching. It takes 2 years, or more precisely 1.5 years, for the female flowers to become the
donguri.
Namely, the female flowers now being pollinated become matured and produce the
donguris in the autumn of next year.
