Title: Three-gear type pump
Inventor: SHIMOMURA ATSUSHI
IPC: F04C14/00
Filed: 1981-02-10
Abstract: PURPOSE:To reduce pulsation in the discharge quantity of a three-gear type pump considerably, by arranging a central gear of each gear set with a phase difference of 1/4 pitch from each other. CONSTITUTION:A central gear 13 is designed to have an odd number of teeth, so that the waveform of discharge quantity of a pump has a phase of 360/2Z (where Z is the number of teeth of the central gear 13). Resultantly, the total discharge quantity of two pumps at the outlet 10 of fluid is 360/2Z and variation in the discharge quantity is DELTAQ/2. Further, the average discharge quantity is 2QM. Therefore, the period of variation is reduced to 1/2 while variation in the discharge quantity is reduced to 1/4. Thus, it is enabled to reduce pulsation of the discharge quantity considerably.

IPC: G01S17/02
Filed: 1991-02-15
Abstract: PURPOSE:To avoid mutual interference stably. CONSTITUTION:Continual constant voltage of proportional relation to a light receiving quantity is obtained by the use of a sample-hold circuit 16. The output voltage of the sample hold circuit 16 is input into a voltage control oscillator 17 to control an oscillation cycle. When a light receiving signal exists, a pulse in accordance therewith is driven. In addition, the light receiving signal is detected in synchronous circuits 25, 30 synchronized with the frequency of the voltage control oscillator 17. Accordingly an oscillation period changes not only for the outside light from other photoelectric switches and the like, but also for self light. In addition, even if the oscillation period changes for the light from the same kind of the photoelectric switches, it is lessened to become closely resembled.
