Title: Piston ring wear measurement system
Inventor: FUKUTOMI MASATOSHI
IPC: G01B11/00
Filed: 1987-10-23
Abstract: PURPOSE:To always monitor a wear condition of a piston ring, by determining a difference between the width of the piston ring before the start of operating of an engine or the like and that during the operation thereof with a measuring device having an optical fiber to calculate the amount of wear of the piston ring according to said difference. CONSTITUTION:When a piston ring C is at a position where light emitted from a light source 3 is to hit an end of an optical fiber 1 for incident light, said light is reflected on the piston ring C and the reflected light is received with an optical fiber 2 for reflected light is received with an optical fiber 2 for reflected light and converted with a light receiver 4 into an electrical signal to be sent to an arithmetic unit 6. The arithmetic unit 6 determines the time during which the piston ring C reflects the light from the electrical signal from the light receiver 4 and also does a moving speed of a piston A from an electrical signal from a sensor 7 for detecting marks. Thus, the width of the piston ring C is calculated from the reflection time of the light and the moving speed of the piston A.

Title: Speed controller for dc motor
Inventor: SUGANO SATORU
IPC: H02P7/29
Filed: 1990-10-03
Abstract: PURPOSE:To improve the efficiency of the title controller without requiring any space by providing a means which detects the induced voltage of a motor while the power supply to the motor is stopped and another means which controls the power supplying time to the motor on the basis of the detected voltage. CONSTITUTION:The high-level time of a pulse generation circuit 6 is adjusted in accordance with the output a sampled operational amplifier 4 and the high- level time of the circuit 6 is held by a sample and hold circuit 5. The circuit 5 is set to a holding state while a high level is supplied to a terminal 5a. Accordingly, the magnitude of the induced voltage of a motor 1 controls the power supplying time to the motor 1. For example, the power supplying time becomes longer during the period (b), since a load is applied to the motor 1 and the induced voltage drops. The power supplying time becomes shorter during the period (c) in order to reduce the rotating speed of the motor, since the rotating speed of the motor is so fast that the induced voltage becomes higher.
