Title: Leaked liquid recovery device for low temperature tank with liquid prevention bank
Inventor: YAMADA TADAO
IPC: F17C13/12
Filed: 1981-02-16
Abstract: PURPOSE:To enable a fast recoverying operation and a fast repairing of a low temperature tank by a method wherein the leaked liquid in a liquid prevention bank is suctioned to separate the low temperature liquid and the gasified gas, and each of them is guided into the recovery tank and the gas recoverying processing means. CONSTITUTION:There is provided a pipe 5 of which one end is inserted into the pit 4 for accumulating the leaked liquid L from the low temperature tank 1 and the other end is projected out of the bank 3 beyond the liquid prevention bank 3. The pipe 5 is provided with a tank 6 for storing the low temperature liquid L transparented from the pit 4, and a pump 9 for use in transporting the low temperature liquid L is arranged between the bottom part of the tank 6 and the recovery tank. The gasified gas G fed from the low temperature liquid L is compressed by a gas suction machine 7 and then recovered by the gas recoverying and processing means.

Title: Electric leakage alarming breaker
Inventor: ISHIGAMI YOSHIHISA
IPC: H01H83/02
Filed: 1991-02-15
Abstract: PURPOSE:To use an electric leakage breaker as an electric leakage alarming breaker with a simple circuit addition by holding the output of an alarming signal at the time of electric leakage occurrence and testing and releasing the holding state by operating a test button while the alarming signal is outputted. CONSTITUTION:In the case that an electric leakage detecting circuit 2 detects electric leakage and an alarming signal is output, when a test button S1 is turned on, a capacitor C1 is charged and a transistor TrQ2 is turned on and electricity supply is stopped and a circuit 2 is re-set. Then, when the button S1 is turned on at testing time, the circuit 2 detects the electric current of a zero-phase current transformer and operates TrQ1 and a relay Ry and an alarming signal is outputted. At that time since the TrQ3-Q5 are on, the capacitor C1 is limited to the level not to turn the TrQ1 on and electric power supply is not stopped and thus the circuit 2 holds the alarming. Consequently, the testing button can be used as a resetting button.

Title: Displacement sensor
Inventor: ONO MASAAKI
IPC: G01D5/20
Filed: 1988-02-02
Abstract: PURPOSE:To prevent transistors from deteriorating in characteristics even when used for a long period by providing a couple of diodes which are connected between the bases and emitters of the transistor and cut off a negative overvoltage. CONSTITUTION:The couple of diodes 23a and 23b are connected between the bases 9a and 9b and emitters 7a and 7b of the transistors 8a and 8b. The diodes 23a and 23b short-circuit negative voltages generated between the bases and emitters when the transistors 8a and 8b are off to cut off the negative overvoltage. When the transistors 8a and 8b are on, the diodes 23a and 23b are applied with opposite-directional voltages and the diodes 23a and 23b turn off, so that there is no hindrance to operation. Further, a couple of 3rd resistances 24a and 24b are connected between the bases 9a and 9b and parallel connection circuits 12a and 12b. Then when a surge is superposed on the input voltage, the resistances 24a and 24b prevent overcurrents from flowing to the bases 9a and 9b and emitters 7a and 7b of the transistors 8a and 8b.

Title: Heating controller of automatic vending machine
Inventor: HORI MITSUHIRO
IPC: G07F11/70
Filed: 1995-02-09
Abstract: PURPOSE: To enable proper heating by detecting commodity storage temperature and varying a heating time according to the temperature as to an automatic vending machine which has a microwave oven built in. CONSTITUTION: When a commodity is selected, a control part 1 consisting of a CPU 2, a storage part 3, and a timer 4 detects the commodity storage temperature by a storage temperature detecting means 5. A specific heating time corresponding to commodity storage temperature of each commodity is previously inputted to the storage part 3 from a setting part 6 and stored, so the control part 1 reads the heating time corresponding to the said commodity storage temperature out of the storage part 3 and the timer 4 sends a heating instruction based upon the heating time to the microwave oven 7. Under this control, the commodity is properly heated in consideration of the commodity storage temperature.

Title: Constant velocity universal joint
Inventor: IWASAKI KEIJI
IPC: F16D3/20
Filed: 1987-01-31
Abstract: PURPOSE:To reduce the sliding resistance of a constant velocity universal joint by providing its outer ring with a roller guide face, and making its outside ring roll properly along a track groove formed in the axial direction of the outer ring. CONSTITUTION:The periphery of an inside ring 21 is formed with a spherical peripheral face 24, and the periphery of an outside ring 22 is formed with a spherical peripheral face 25 guided by a roller guide face 13. When a coupling is situated at an operating angle, the inside ring 21 inclines toward the outside ring 22, and moreover moves relatively downward in the cylindrical inner periphery 28 of the outside ring 22. Thus the roller guide face 13 of the outer ring 10 guides the outside ring 22, which can roll properly on the roller guide face 13 to reduce the sliding resistance of an universal coupling.

Abstract: PURPOSE:To facilitate the quality control of the soldering part by connecting a bottom plate to frame-form body parts with bridges extending between the corners of the bottom plate, and arranging connecting tab parts to clearances between the side edges of the bottom plate and the side walls of the frame-form body parts. CONSTITUTION:A central bottom plate 14' surrounded by frame-form body parts 10' is connected by connecting the frame-form body parts 10' with only four bridges 32 extending between the corners 33 of the bottom plate 14' integrally, while clearances 22' in which there is no bridge are formed between the bottom plate 14' and the frame-form body parts 10', and combining tab parts for soldering each contact are visibly arranged in the clearances 22'. As a result, since there is no bridge in the lines of connecting tab parts lined up in the clearances 22', the soldering pad lines can be recognized visually through the clearances 22', and furthermore, a fear of generating a solder bridge can be minimized. And even though a solder bridge is generated, it can be confirmed clearly from the upper side of the socket, and a soldering iron can be easily accessible to the clearances 22'.
