Title: Structure for preventing entry of water in electric device
Inventor: TAGUCHI YOSHINORI
IPC: H05K7/00
Filed: 1998-06-25
Abstract: PROBLEM TO BE SOLVED: To prevent failures such as leak, etc., in an ultrasonic washer, etc. SOLUTION: A circuit board 13, etc., are housed in the inside of an ultrasonic washer body 1. A cover 19 is fitted to the lower part of the body 1 and a housing space 20 is formed between the body 1 and the cover 19. An inlet 21 is fitted to the cover 19. Then the inside of the body 1 communicates with the housing space 20, and a connecting hole 17 for providing a lead wire 22 connecting the circuit board 13 with the inlet 21 is made above the inlet 21. When a washing liquid is removed from a washing tank 6 by tilting the body 1, it often flows on the lower body 1 and enter the housing space 20 through a clearance between the inlet 21 and fitting hole 18. However, since the connection hole 17 is formed at higher position than the inlet 21, the washing liquid hardly enter the body 1 along the lead wire 22 and arrives at the circuit board 13.  Further, this washer can be assembled easily only by passing the lead wire 22 through the connection hole 17, resulting in simplified structure.

Title: Fm demodulating circuit
Inventor: MATOBA TSUNEAKI
IPC: H03D3/02
Filed: 1981-11-06
Abstract: PURPOSE:To eliminate the generation of an impulse noise when the degree of control is large by applying a control voltage generated in accordance with the degree of modulation of an FM signal from the output of a PLL demodulating circuit to a loop filter, and controlling a synchronism range when an electric field is weak by said control voltage. CONSTITUTION:At the output of a PLL demodulating circuit 6, a control voltage corresponding to the degree of modulation of the carrier in an FM signal is generated and then applied to the loop filter 7 in the PLL demodulating circuit 6 to control the synchronism range of the PLL when an electric field is weak by said control voltage. Consequently, while an S/N ratio when the electric field is weak is improved by sufficient band compression, the synchronism range of the PLL is controlled in accordance with the level when the degree of modulation is large, thereby suppressing the generation of distortion due to an impulse noise.

Title: Vent-type sintered alkaline storage battery
Inventor: MURATA TOSHIO
IPC: H01M10/24
Filed: 1985-08-14
Abstract: PURPOSE:To prevent the hydrogen overvoltage of a negative electrode plate of cadium from rising when floating charge is performed at a high temperature for a long period of time, by electrically connecting a sintered nickel hydroxide electrode plate to the negative electrode plate. CONSTITUTION:When a sintered nickel hydroxide electrode plate, which would conventionally be used as a positive electrode plate, is subjected to cathodic polarization in an alkaline electrolytic solution to generate hydrogen, the hydrogen overvoltage of the plate is much lower than that of a sintered negative electrode made of cadmium and having the same volume as the former. When the polarizing properties of the sintered nickel hydroxide electrode plate and the sintered negative electrode plate of cadmium as to their hydrogen generating reaction in an electrolytic solution of KOH at 5M were compared with each other, it turned out that the electrical current through the sintered nickel hydroxide electrode plate was about 50 times as much as that through the sintered negative electrode plate of cadmium at the same polarization value. This means that the volume of the sintered nickel hydroxide electrode plate which minimally necessary to attain the same polarizing property as the sintered negative electrode plate of cadmium with regard to the hydrogen generating reaction is 1/50 of that of the latter.

Title: Data transmission system
Inventor: SATO TADASHI
IPC: H04L69/40
Filed: 1988-07-21
Abstract: PURPOSE:To respond to requests of various external input/output circuits by discriminating abnormality at transmitting sources or on their transmitting routes by checking transmitting intervals from each transmission station and cutting off or holding outputs of the input/output circuits. CONSTITUTION:Data are periodically transmitted to each transmission station 1 and the microprocessor (MPU) 2 of each station 1 is provided with a software counter which counts up at every regular period (several times as long as the cyclic transmission period) to a receiving block and resets its count value at the time of reception. An excess of the count value over a fixed value means that the transmitting source becomes impossible in data transmission due to some abnormality. Therefore, discontinuation of transmitting data caused by abnormality at the transmitting source or its transmitting route can be detected and, at the same time, the cut-off of holding state of the output of an I/O 9 can be designated at the time of the discontinuation. Therefore, the data output state to I/Os can be selected freely at every I/O in response to requests at the time of detecting abnormality.
