Title: Alkaline battery and its negative electrode active material
Inventor: NAKAMURA KIYONOBU
IPC: H01M4/06
Filed: 1988-09-27
Abstract: PURPOSE:To suppress generation of hydrogen gas by using negative electrode material to which a specific amount of alkoxypolyethyleneoxide sulfonate is added. CONSTITUTION:For an alkaline battery, negative electrode material is used wherein alkoxypolyethyleneoxide sulfonate of 0.001-1.0 weight portion is added to zinc alloy powder 100 weight portion which constitutes the battery. Hereby, during preservation of the battery, alkoxypolyethyleneoxide sulfonate ions are adsorbed to the surface of zinc alloy powder and work as inhibitors, which prevent migration of hydride ions to the surface of zinc, and enlarge hydrogen overvoltage of zinc alloy powder. As a result, corrosion resistance of zinc is improved, and hydrogen gas generation attendant upon the corrosion of zinc is restrained. In particular, even in the case that the inclusion ratio of mercury is made ultralow mercury amounts being below 0.2weight% of zinc alloy powder to be used, hydrogen gas generation in the battery is suppressed, and further the battery performance is maintained at high level. Also, since the mercury can be made the low inclusion ratio, it can meet the social needs.

Title: Air turbine suction implement of vacuum cleaner
Inventor: MIKAMI KATSUMASA
IPC: A47L9/02
Filed: 1992-09-09
Abstract: PURPOSE:To decrease a noise, and to enlarge generated torque by allowing the center shaft of a nozzle and the split surface of an air turbine impeller to coincide with each other, and forming roughly a funnel shape of a socket of a swivel asymmetrically against the center shaft of a suction implement. CONSTITUTION:Suction air 32 comes into collision with a blade 4a of an air turbine impeller 4, and a speed difference to a discharge air current 9 after the collision works as a momentum and generates torque. By this torque, a rotary brush 13 is rotated through a shaft 10, a pulley 11, and a timing belt 12. The air current 9 after the collision passes through a gap between the impeller 4 and the bottom face of the lower case 2, while diffusing along a circular arc of a side wall 4d of the impeller 4, and is discharged to a socket 22 of a swivel 15. The greater part of the discharge air current 9 is sucked into an L-shaped joint 23, but a partial air current 9a diffused by the impeller 4 hits against a rear wall 19 of a turbine chamber 16 and a side wall 22b of the socket 22. However, it is sucked quickly into the L-shaped joint 23, since the rear wall 19 and the side wall 22b are streamline by a circular arc of a large curvature, a noise by the air current after the collision becomes low.

Title: Gain control system
Inventor: OZAWA HIROSHI
IPC: H03G1/02
Filed: 1985-10-30
Abstract: PURPOSE:To decrease the variation such as variation depending on a set by providing a means applying A/D conversion to an electric field of a code sectioning signal section supplied to an identification code and outputting a control output when the A/D value is a threshold value or over. CONSTITUTION:As the result of the depression of a switch SW for the purpose of locking, a radio wave sent from an equipment possessed by the operator is reproduced into a pulse waveform corresponding to the original specific code through a high frequency amplifier circuit 1, a detection circuit 2 and a waveform shaping circuit 3. When the side code is inputted to a microcomputer 4 and the code is coincident, the lock output is made and the misplacement detection is applied. The electric field of the start bit part of the radio wave is numerized by an integration A/D conversion using a comparator 4, the timewise change of the value is checked to judge the presence of movement thereby judging whether or not the misplacement takes place. When it is judged to be misplacement, a sensitivity reduction output decreases the gain of the circuit 1. The lock output allows an output when the output has a digital threshold value.
