Title: Alkaline battery
Inventor: SHINODA KENICHI
IPC: H01M4/06
Filed: 1984-07-11
Abstract: PURPOSE:To prevent the corrosion of powdered zinc, by causing iron to cling to the surface of each grain of the powdered zinc in a negative electrode so as to compensate for the drop in hydrogen overvoltage which is caused by the low amalgamation or non-amalgamation of the powdered zinc in the cathode. CONSTITUTION:An iron hydroxide or an iron oxide is caused to cling to the surface of each grain of powdered zinc to coat the grain with a film. The powdered zinc is then mixed with carboxymethyl cellulose and an alkaline electrolyte. The mixture is made into a gel, thus manufacturing a negative, electrode. The optimal quantity of the iron hydroxide or the iron oxide is such that the amount of the iron is within a range 10-100ppm to the weight of the powdered zinc. If the amount of the iron is out of the range, the hydrogen overvoltage of the powdered zinc in the negative electrode becomes too low to prevent the unnecessary corrosion of the powdered zinc and suppress the quantity of generated hydrogen gas of a battery within an allowable range.

Abstract: PURPOSE:To accomplish a heatproofing on the wall surface of a vessel for low temperature material, for example, a vessel for transporting a low temperature liquified gas such as LPG by heat welding of a heat resisting layer covering the intended wall surface of the vessel and a molded panel applied on the end rim of the area to be worked. CONSTITUTION:Heat insulating materials 5 of a molded panel 4 are thermally welded to each other while outer casings 6 are connected to each other by lock seaming or the like to form a heatproof panel necessary in the length and width enough to cover the working area, which is positioned at working places on the wall surface 2 of a vessel. On the other hand, a heatproof panel a' formed from a molded panel 4 is bonded at the end rim of the working area of the wall surface 2 of the vessel beforehand. The opposing rims of the heatproof panel a and the heatproof panel a' thermally adheres to each other while the opposing rims of the outer casings 5 are joined together by lock seaming or the like.

Title: Electronic watch
Inventor: SHIDA MASAHARU
IPC: H02P8/02
Filed: 1977-12-02
Abstract: PURPOSE:To effect the drive in accordance with a load applied thereby to reduce the electric power by feeding drive pulses to a step motor, while having their width stepwise elongated or shortened, so that the operation may be started with the drive pulses of the minimum width after the stopped condition is released. CONSTITUTION:The drive pulses of a step motor are composed of two kinds of normal drive pulses P1 and auxiliary drive pulses P2. If the step motor cannot be turned by the normal pulses P1, the auxiliary pulses P2 are supplied. With the supply of the auxiliary pulses P2, the pulse width of the subsequent normal pulses is so elongated to facilitate the rotations. When, on the contrary, the rotations can be accomplished several steps, the width of the subsequent pulses is shortened. Thus, the supply of the drive pulses can be effected stepwise. When the time metering is restarted after the stop, the normal drive pulses have their width set at the minimum one of the pulse width prepared, and thereafter the stepwise supply is accomplished.

Filed: 1989-06-07
Abstract: PURPOSE:To prevent a signal from being reproduced at a receiving side other than an object receiving side by multiplexing a noninverting optical output and an inverted optical output outputted from plural laser diodes with different wavelength at a multiplexer, sending the synthesized signal to an optical fiber, demultiplexing the received optical output at the receiving side with a demultiplexer for each wavelength and reproducing the signal into an original signal. CONSTITUTION:A noninverting output is outputted from one of two laser diodes 3, 4 generating an optical output with a different wavelength and an inverted output is outputted from the other, the outputs are multiplexed by a multiplexer 5 and sent to an optical fiber 6, the receiving side demultiplexes the received optical output for each wavelength and photodiodes 8, 9 reproduce the output into the original signal. Thus, the intensity of the optical output sent in the optical fiber 6 is almost unchanged. Even when the signal is leaked from the optical fiber 6 during the transmission, the receiving side not having a demultiplexer demultiplexing the incoming optical output for each wavelength cannot reproduce the signal.
