Title: Lash adjustor for internal combustion engine
Inventor: UMEDA MINAO
IPC: F16L55/00
Filed: 1992-04-09
Abstract: PURPOSE:To previously separate air dissolved in oil which is introduced into the high pressure chamber in a lash adjustor, so as to improve reliability of the device. CONSTITUTION:A generating means (oil introducing port) 3 by which cavitation is generated in oil when fluid passes therethrough is provided between an oil intake means (oil introducing port) 3 and a high pressure chamber 29, in a lash adjustor 10. The diameter (d) of the oil introducing port 3 and the diameter (d') of an oil outlet 31 are in relation of (d)<(d'). Consequently, air dissolved in oil to be fed to the high pressure chamber 29 is separated by the generating means, removed before being introduced into the high pressure chamber 29, and hence essential function of the lash adjustor can be realized even at restart of an internal combustion engine.

Title: Pulse input circuit
Inventor: MATSUSHITA YUUJI
IPC: H03K5/1252
Filed: 1982-05-26
Abstract: PURPOSE:To discriminate whether an input pulse is a normal signal or noise, by comparing an input signal with an output of a bistable multivibrator and inverting the output of the bistable multivibrator only when the result of comparison is different from each other by a prescribed time or over. CONSTITUTION:The input signal A and the output G of the bistable multivibrator 4 are compared by a comparison circuit 1, and when the result of comparison is different, a logical value 1 is outputted and when the two are equal, a logical value 0 is outputted. An oscillator 2 outputs a sampling pulse C, and when the signals A and G are different, an AND gate G1 is conductive, and when the count of the sampling pulse is a prescribed value or over, a pulse signal F is generated and the bistable multivibrator 4 is inverted. Since a signal B is 0 when the signals A and G are equal, an AND gage G2 is conductive, and when the count of the sampling pulse is a prescribed value or over, a counter 2 is reset. Although the signal G is changed with a prescribed time delay from the signal G, the circuit is not affected by a short-time noise.

Title: Lincompex radio equipment
Inventor: KOBAYASHI ATSUSHI
IPC: H04B14/00
Filed: 1980-06-27
Abstract: PURPOSE:To improve the performance of a radio equipment by providing a means of detecting the level of a frequency component in a specified range and another means of controlling the level of a reduced carrier corresponding to the detected level. CONSTITUTION:A composite signal of a reduced carrier signal as frequency component information and a subcarrier FM signal as amplitude component information is sent out via an SSB transmitter 8. Then, a specified-range level detection part 19 detects the level of a frequency component between (F-B/2)/2 and (F+B/2)/2 from the output part of an amplitude compression part 2. (A frequency-band center frequency in the base band of the subcarrier FM signal is denoted as F and the band width as B, respectively.) When this detected level is large, a reduced carrier level control part 20 operates to decrease the reduced carrier level. Therefore, when the number of frequency components in the specified band is small, the reduced carrier level is increased, so the performance of the device is improved.

Title: Cleaning device for image forming device
Inventor: KUME NOBUYUKI
IPC: G03G21/10
Filed: 1990-04-04
Abstract: PURPOSE:To always stably perform an excellent cleaning action by providing a means for preventing a cleaning blade and a supporting member from sticking each other on the surface of the supporting member which comes in contact with the cleaning blade. CONSTITUTION:The cleaning blade 1 is interposed and held by the supporting members 2 and 3, and lubricant member 5 is disposed at a part where the member 3 abuts on the blade 1 and a part where a thin plate 4 abuts on the blade 1. Therefore, in the case of detaching the blade 1 so that the edge of the blade 1 press-contacting with an image carrier may be exchanged, the sticking of the blade 1 to the member 3 and the thin plate 4 is prevented. Even when the abutting state of the blade edge on the image carrier is a little irregular, local load fluctuation and stress are absorbed much by force exerted from the image carrier side and a press-contact action is made uniform, thereby preventing defective cleaning and filming from occurring. Thus, the excellent cleaning action is always maintained.

Abstract: PURPOSE: To regenerate an ion exchanger efficiently without using chemicals by passig cation and anion exchangers separately between electrodes and processing electrochemically.  
     CONSTITUTION: An anion exchange belt 2 and a cation exchange belt 3 ion exchanged by liquid to be treated are made to pass through between a cathode 6 and anodes 7, 8, and voltage is applied between electrodes 6, 7, 8.
