Title: Conservator device of oil-immersed transformer
Inventor: HORIUCHI KATSUJI
IPC: H01F27/14
Filed: 1986-04-21
Abstract: PURPOSE:To measure an oil level uisually from outside, by opening a solenoid operated mobile open-and-close valve by remote control, so that the insulating oil in a conservator box is introduced into a transparent pipe in bipass piping. CONSTITUTION:An electrical mobile open-and-close valve 16 is operated by remote control in a control board or the like, to open the valve. The valve 16 is located below the bottom part of the conservator box 3. Because the valve 16 is under oil-pole pressure from the level of an oil, the insulating oil 2 in the box 3 is heaved up toward a transparent pipe 14 and is raised to the same height as the oil level in the box 3. By reading out the value, when the oil level in the pipe 14 becomes stable, becomes a true value of the oil level. When the oil level is measured and then the valve 16 is closed by remote control, the level of the insulating oil 2 falls in a non-pressure tightly-closed state again. Hence, the true oil level can be measured from outside uisually.

Title: Manufacture of plate for lead-acid battery
Inventor: MORIMOTO YOSHINARI
IPC: H01M4/22
Filed: 1982-05-28
Abstract: PURPOSE:To improve performance of a lead-acid battery by reforming in electrolyte having lower temperature than electrolyte temperature in completion of formation when nonformed plates using antimony-free lead alloy as a current collector are formed in dilute sulfuric solution, and manufacturing plates having reduced residual lead sulfate. CONSTITUTION:Nonformed plates using as a current collector lead alloy which is actually antimony-free in a part or the whole of a substrate are formed in a dilute sulfuric acid. After completion of formation, current is cut off. The plates are recharged in electrolyte having lower temperature than electrolyte temperature in comperation of formation. By this process, lead sulfate remaining in the plates can be reduced. Self discharge and charging property of a lead- acid battery using these plates are improved.

Title: Automatic control method for preventing landing rope looseness of overhead crane with bucket
Inventor: ODA KAZUO
IPC: B66C13/10
Filed: 1993-03-26
Abstract: PURPOSE:To prevent a rope from loosening by providing a counter for storing a time to a deceleration stop of lowering action, calculating a loosening amount of the rope from a counter value in the point of stop time, and operating a crane in a hoisting up direction only for a time in proportion to the calculating result. CONSTITUTION:When a landing detector 2 operates during lowering a bucket, a control time (T) from this time of operating the detector to stopping a motor 5 is counted simultaneously with outputting a lowering stop command, to decelerate the bucket stopped. Counting this control time T is a deceleration time of the bucket, and since it is almost in proportion to a rope loosening amount, the rope loosening amount TXalpha1 is calculated by an arithmetic unit 3. In the point of time of decelerating the bucket stopped, when the calculated rope loosening amount TXalpha1 is driven in a hoisting up direction, looseness of a rope is eliminated. This hoisting up time is set to TXalpha1Xalpha2, and inching hoisting up is performed by a hoisting up/lowering control unit 4 for operating the bucket hoisting up/down by a signal from the arithmetic unit 3.

Abstract: PURPOSE:To attain the safe loading/unloading of a cassette in any direction by defining three positions where a cassette loading cover is set in a record/reproduction mode, where the cassette which could not be inserted is tentatively fixed at the inserting position and where a mechanism is actuated to push the cassette out up to a position where the cassette is easily taken outside. CONSTITUTION:When a cassette cover 2 is released with operation of a release button, both the cover 2 and a cassette holder 12 are opened by a spring 1. A cassette 3 is hooked by a tentative fixing member 27 and never comes out in any position of the main body of a cassette loading device. When the cover 2 is opened more, a plate 587 is held up to open the holder 12 against a spring 59. A hook part 24 at the opposite side to the holder 12 engages a part 250 of the main body at a bent part 24a. Thus a cassette ejection member 20 is released, and the cassette 3 is ejected against the restricting force of the member 27. In this case, a shutter 6 is closed by a shutter closing member 15 and in accordance with ejection of the cassette 3. Under such conditions, the cassette 3 is set in a free state and can be manually taken out.
