Title: Angular velocity sensor
Inventor: KIMURA RIYOU
IPC: G01C19/5607
Filed: 1984-03-22
Abstract: PURPOSE:To improve the sensitivity of detection by a construction wherein a pair of sensor elements formed by joining driving and detecting piezoelectric elements to each other at a prescribed angle are arranged in parallel and the respective piezoelectric elements are joined together by a joint member, while the joined elements are supported on a base member by an elastic member. CONSTITUTION:With the surfaces of driving piezoelectric elements opposed to each other used as a common electrode, an AC signal (resonant frequency) is applied between these surfaces and the respective outside surfaces of the elements, and the piezoelectric elements 2 to which the signal is applied are made to vibrate in a phase of 180 deg. with a joint member 3 used as a base. The appropriateness of the piezoelectric elements depends on detecting piezoelectric elements 1, the driving piezoelectric elements 2, a joining member 6 and a bonding agent. As for an elastic member 4 for adjusting right and left vibration elements, a material having a high Young's modulus and shaped in a slender pipe is selected therefor. This construction enables the attainment of an angular velocity sensor which has a complete canceling effect on disturbance noise and a high detection sensitivity and is excellent in linearity.

Abstract: PROBLEM TO BE SOLVED: To make a thermal expansion valve small and light weighted by reducing a sealing resistance of an actuating rod which is operated to open and close a valve member in the thermal expansion valve which is mounted in an air conditioner. SOLUTION: A valve body 30 is made of a body of a conventional thermal expansion valve, wherein a rod member which constitutes a thermo-sensitive bar 36f is made of a shaft having a small diameter. The rod member is reciprocally driven to transverse a passage 34 in response to a displacement of a diaphragm 36a of a power element 36 to form clearances (gaps) 37, 38 which allow a passage 321 and a passage 341 to communicate with each other. To seal these clearances, an X ring 50 which intimately comes into contact with the outer peripheral surface of the rod member is disposed in a hole 38 of a large diameter and is located between passages.  Furthermore, for preventing the movement of the X ring 50 which may be caused by a force acting in a longitudinal direction (the direction heading for a place where the power element portion 36 is present) due to a coil spring 32d and a refrigerant pressure in the passage 321, a push nut which works as a return stop ring is mounted on the rod member such that the push nut is disposed in the groove 38 of a large diameter and comes into contact with the X ring 50.

Title: Production of high-purity bisphenol a
Inventor: IIMURO SHIGERU
IPC: C07B61/00
Filed: 1988-03-11
Abstract: PURPOSE:To respectively feed the first mother liquor and second crystals to respective other steps in a main step for obtaining the first crystals and first mother liquor from a reaction solution of phenol and acetone and an auxiliary step for obtaining the second crystals and second mother liquor from a reaction solution of p-isopropenylphenol and phenol. CONSTITUTION:Part of phenol, catalyst, water, etc., are removed from a reaction solution of phenol and acetone to regulate their concentrations. The resultant solution is cooled and subjected to solid-liquid separation to provide the first crystals consisting of adduct of bisphenol A with phenol and the first mother liquor. The phenol is then removed from the first crystals to provide the bisphenol A in a main step. p-Isopropenylphenol is subsequently reacted with phenol to carry out similar operation and afford the second crystals and second mother liquor in an auxiliary step. The first mother liquor is fed to the auxiliary step and the second crystals are fed to the main step to provide the high-purity subject substance. Since reaction by-products are cleaved simply by passing through part of the main and auxiliary steps only once, the contamination of the respective steps is minimized without causing circulation and accumulation in the main step.

Title: Variable pn checker
Inventor: TAKEDA YUTAKA
IPC: G06F11/22
Filed: 1991-03-20
Abstract: PURPOSE:To use only one PN checker and to reduce the circuit scale by using a clear signal and select signals of a number resulting from decreasing one from number of FFs to check plural PN patterns. CONSTITUTION:A PN pattern input is preset and two selectors 2 and a clear signal CL are selected by using a selection signal S. The selected selector connects an output of a relevant FF and an output from a pre-stage selector to one terminal of the selector for the transmission of a selector signal. A selector not selected connects an output from the pre-stage selector to a terminal 0 to bring the succeeding selector to be a through-state. Select signals of the two selected selectors are processed by an EXOR 3 and the result is fed to a check use EXOR 4, in which the resulting output from the selector is compared with the PN pattern input and a check result is sent from the EXOR 4. The shift operation of the FF is cleared by clearing a clear terminal CL of a final stage FF1n and when the FF repeats shift operation when the FF is not cleared.
