Title: Hydraulic vibration actuator
Inventor: SHINOHARA MASATOSHI
IPC: F03C1/26
Filed: 1979-02-28
Abstract: PURPOSE: To smoothly shift the operation of a hydraulic vibration actuator from its accelerated driving mode by use of accumulated energy to that by use of hydraulic pressure of supplied oil, by dividing a corresponding oil chamber into an oil supplying and discharging chamber and a reaction chamber by a reaction chamber defining means each time when the piston comes near to the end portion of its stroke.  
     CONSTITUTION: Between piston 6 and at least one (2) of opposite end walls 2, 3 of cylinder 1, there is formed an oil chamber 4, which is divided, by reaction chamber defining means (consisting of peripheral wall 15 and mating portion 21), into an oil supplying and discharging chamber 22 that is communicated to oil supplying and dischargeing passage 7 when piston 6 comes near to the end portion of its stroke on the side of end wall 2 and reduces its volume along with movement of piston 6 toward end wall 2 and a reaction chamber 23 spaced apart from the passage 7, the volume of which is also reduced along with movement of piston 6 toward end wall 2. By thus dividing the hydraulic chamber, operation of a hydraulic vibration actuator can be shifted smoothly from its accelerated driving mode by use of accumulated energy to that by use of hydraulic pressure of supplied oil, so that generation of noises can be eliminated effectively.

Filed: 1992-02-10
Abstract: PURPOSE:To eliminate waste in energization time with higher rinsing efficiency by rinsing water by arranging a heater in a tank in which a rinsing water is accumulated for supply to a rinsing nozzle to accomplish energization of the heater simultaneously with the operation of a water pump. CONSTITUTION:With a controller C, a heater 28a begins to be energized with the operation of a water pump 30 and the heating of a rinsing water which is accumulated in a rinsing tank 28 is started. As compared with a cold rinsing water, the heated water gets higher rinsing efficient to allow the finishing of the rinsing in a short time. The energization of the heater 28a begins with the start of the rinsing, eliminating waste in the energization time. The heater 28a is tuned OFF with the start of the final step of a rinsing process and hence, the final step uses the hot water left in a rinsing pipe 31 and a rinsing pipe 31b, which also eliminate waste as caused by the leaving of the hot water in the rinsing pipe 31 and the rinsing pipe 31b. The setting of turning ON or OFF of the heater 28a beforehand enables the energization of the heater 28a efficiently without a sensor.

The respective address signals are corresponding to distances from the centers of pupils of relevant eyes to the symmetric vertical axis of the front panel and the total of both the distances become the inter-pupil range. The inter-pupil range and the distances from the symmetric vertical axis to the left and right pupils are displayed by the logic device 20.
