IPC: F16H7/12
Filed: 1988-09-22
Abstract: PURPOSE:To prevent the occurrence of a slip between an energizing member and a friction member, to suppress the swing of a belt, and to follow the occurrence of slack by a method wherein the energizing member and the friction member are constrained in the inner wall of a recessed part, formed in a position displaced from the rock center of a rock arm, in a manner to be incapable of relatively displacing CONSTITUTION:Through the force of a twist coil spring 60, a rock arm 20 is always energized clockwisely around a bolt 42 serving as a rock center, and a pulley 30 supported to the free end of the arm 20 is pressed against a belt 40. Through the expansion force of a compression spring 23 contained in a recessed part 22 of a boss 21, a friction member 24 is forced into pressure contact with a base plate 51 of a normally-secured intermediate member 50. Thereby, enough rock resistance is exerted on the arm 20 by means of friction resistance created between the friction member 24 and the base plate 51. Thus, even when, during rock of the belt 40, a reaction force from the belt 40 is exerted on the arm 20 through the pulley 30, the arm 20 is prevented from wandering until a belt reaction force exceeds a friction force, resulting in the possibility to suppress vibration of the belt 40.

Title: Differential pressure measuring apparatus with flange
Inventor: YAO HIRONOBU
IPC: G01L19/00
Filed: 1990-09-07
Abstract: PURPOSE:To obtain an apparatus capable of measuring the differential pressure even when one fluid related to the differential pressure is at high temperature by providing a radiation means for a coupling body of a flange and a differential pressure detector. CONSTITUTION:A coupling body 10 formed of material with high thermal conductivity passes through a central hole 11 having a liquid sealed in the central part thereof. One pressure P1 is transmitted to a differential pressure detector 1 via the central hole 11. The coupling body is provided with a spiral flow- through hole 12 for a refrigerant liquid around the central hole 11. While a refrigerant liquid enters from an opening of the flow-through hole 12 and flows while turning in the periphery of the central hole 11, the liquid absorbs the heat of a liquid to be measured at high temperature and then flows outside. Accordingly, even when the liquid to be measured is of high temperature, proper measurement is achieved.

Abstract: PURPOSE:To converge digital data correctly on (0000)H when an input signal is zero by opening an offset feedback loop when the digital data becomes all zero and closing the offset feedback loop when said data is not in the all-zero state. CONSTITUTION:An analog signal inputted through an offset adjusting circuit 4 is converted by an AD converter 6 into digital data of 'complement on 2' by an AD converter 6. Then the most significant digit bit MSB of the digital data in inputted to a low-pass filter 8 of <=1Hz in synchronism with a sampling frequency and the offset adjusting circuit 4 performs control according to the output of a low-pass filter so as to cancel an offset voltage. Further, when an all-zero detecting circuit 9 detects the all-zero state of the digital data, a switching circuit 10 opens the offset feedback loop OFSL to stop the offset control and when the data is not in the all-zero state, the offset feedback loop is closed to restart offset feedback. Consequently, when the input is zero, the digital data in converged on (0000)H.
