Patent JP-S58132639-A (JP)
Title: Differential pressure transmitter
Inventor: HIDA TOMOYUKI
IPC: G01L13/02
Filed: 1982-02-03
Abstract: PURPOSE:To prevent fluctuation of a zero point under a high static pressure, by a method wherein a deformed volume produced due to an elastic deformation amount of a pressure receiving part is made equal using an elastic member. CONSTITUTION:Respectively in a high pressure side member 10 and a low pressure side member 20, a portion in the proximity of a connecting path 50 at each mating spot consists of an elastic member 55. A periphery of a diaphragm 40 positioned between the nip formed by the members 10 and 20 is welded at an angle of beta deg. (1 deg.-2 deg.) to the surface of the diaphragm 40 for coupling. A change in a volume produced due to deformation of a pressure receiving member at a pressure applying time is absorbed by a deforming volume of the diaphragm 40 to symmetrically bring a change in a zero point, produced owing to an elastic change, into naught. In case an excessive pressure is applied from either of them, the diaphragm 40 has a given rigidity so that it is prevented from seating the members 10 and 20 even if seal diaphragms 30 and 31 seat a stopper, which results in preventing an excessive stress from occurring to a weld, and a zero point after an one-sides pressure is applied is kept stable.

Three phase square waves and triangular waves having the frequency of positive number of times that of said square waves are formed. The counters 17 and 18 are operated in synchronization with the interruption signal in the pulse width modulated waveform which is applied to the microcomputer 14 from the frequency divider 13. Thus the pulse width modulated signal is formed.

Title: Ic card insertion/extraction detection controller
Inventor: SATO KOJI
IPC: G06F1/18
Filed: 1996-01-31
Abstract: PROBLEM TO BE SOLVED: To minimize resources assigned to the detection of card insertion and extraction by providing a slot management information table which contains acknowledgement information on card insertion and extraction and presence/ absence information on a card insertion/extraction event in pairs. SOLUTION: When IC cards 10a and 10b are inserted into or extracted from slots, their insertion or extraction is detected by card insertion/extraction detection parts 7a and 7b, which output detection signals to a card insertion/ extraction management part 5 through a signal line 6. Then the card insertion/ extraction management part 5 holds values of the slot management information table, slot by slot, and checks their changes as to all the slots. When an enable flag is set, a slot where one of card insertion and card extraction events occurs is decided. When the slot is decided, the value of the event occurrence of the slot is set to YES and an interruption signal is sent out to a system control part 2 through an external interruption line 4.

Title: Dust collector
Inventor: AKIBA ISAMU
IPC: B01D47/06
Filed: 1981-02-05
Abstract: PURPOSE: To improve the safety of a dust collector at a low cost, to bring its dust-collecting efficiency to perfection and to protect the meshes of a filtering part from plugging, by arranging a liquid-atomizer at the front stage of a long fiber filter.  
     CONSTITUTION: Before introduced into a filtering part 7, impalpable dust is let wear water on its surface by liquid 12 atomized with a pump 11, so that the dust can be easily collected by the long fibers 7A of a long fiber filter. Thus, a dust-collecting effect is enhanced. In addition, the long fiber filter including the long fibers 7A wears water due to atomization of the liquid 12, so that every particle of the impalpable dust is let further wear water during its passage through the long line of the long fibers 7A. Consequently, the dust increases its particle size and is collected as particles 14 by the long fibers. As a result, the safety is improved at a low cost, the dust-collecting efficiency is made perfect, and plugging of the filtering part can be eliminated.
