Filed: 1987-02-18
Abstract: PURPOSE:To measure a very minute electric charge quantity by connecting a capacitor provided with an electric charge charging and discharging switch to the input terminal of an amplifier to evaluate a floating capacity in an amplifier feedback capacitor. CONSTITUTION:A self-holding relay switch S1 connected in parallel with an amplified 2 connected to an ion chamber collector electrode 1a is periodically opened and closed. While the switch S1 is opened, an electric charge charging relay switch S2 is closed to charge an electric charge charging capacitor Ci from a power source Ei, and simultaneously, a parallel resultant capacity (fedback capacitor CS+floating capacity CSX) is charged, and the charging voltage of an output terminal 3 is measured to evaluate the floating capacity CSX. When the switch S1 is closed, a switch S3 is closed to discharge the capacity. Since opening and closing of switches S2 and S3 are controlled to evaluate the floating capacity in this manner, measurement is performed with a high precision and a high sensitivity even if the capacity value of the feedback capacitor is reduced.

Abstract: PROBLEM TO BE SOLVED: To prevent the emission of stray light from a photodetector by attaching the detecting surface of a light receiving element to a substrate such that the surface is tilted to the incident axis of an optical beam and, at the same time, a shielding means which shields reflected beams from the detecting surface to the substrate. SOLUTION: The detecting surface of the light receiving element (IC chip) 2 of a photodetector 1 is fixed to a substrate 3 such that the surface is tilted at a small angel from the direction perpendicular to the optical axis of incident light. In order to fix the detecting surface in the above-mentioned way, a tilted section 4 having a prescribed tilt angle is provided at the position of the substrate 3 where the element 2 is attached.

Title: Braking device
Inventor: GOTO HARUICHI
IPC: B60T8/40
Filed: 1988-02-18
Abstract: PURPOSE:To prevent sudden change and delay in braking operations by arranging a throttle controlling the flow of brake oil and a valve body communicating a master cylinder with a caliper while being opened when required respectively between a master cylinder device and an anti-skid device. CONSTITUTION:High pressure oil discharged from a master cylinder 1 flows into the throttle valve 9 of a pressure shock absorbing device 3 and a pressure absorbing valve 10 respectively through a pipe 2. And high pressure oil flowing into the pressure absorbing valve 10 lets a piston 14 be moved to the downstream side so as to let oil in the downstream side be forwarded with pressure to an anti-skid device 5 and a caliper 7 via a pipe 4. On the other hand, oil flowing into the throttle valve 9 passes through the throttle 11e of a valve body 11. And after the piston 14 has been moved to the downstream side, the whole amount of oil passes through the throttle 11e. As a result, when the downstream side of the valve body is increased in pressure, the valve body 11 is moved to the upstream side, oil thereby circulates to the downstream side without passing through the throttle 11e. The piston 14 is also moved to the upstream side accompanied with the situation.
