Title: Hydraulic cylinder
Inventor: MURATO KENICHI
IPC: F15B15/14
Filed: 1977-09-16
Abstract: PURPOSE: To provide a hydraulic cylinder of smooth motion and easy processing, by providing a free piston between a piston rod and a cylinder tube and perform an expansion/contraction motion and a rotary motion.  
     CONSTITUTION: Fig. shows the state of accommodation or waiting of a wheel catcher 3. When a vehicle comes at a speed in that state, a vehicle wheel treads a detector means and a detection signal is produced and a changeover valve 70 for turning up and down is automatically shifted to upper position. Then, a pressure chamber 50 of a cylinder 47 for turning up and down is connected to a tank 69 through a pipe 72, the upper position of the changeover valve 70 and a pipe 68. At that time, high pressure remains applied to a pressure chamber 30 of an expansion/contraction cylinder 11. This cylinder 11 is slidably supported at its peripheral surface on bearings 16, 17. A gap extends between the cylinder 11 and the free piston 31 in the axial direction. A pressure chamber 29 is defined between the end of the piston rod and the cylinder 11. Therefore, the cylinder 11 can rotate freely under low resistance without performing mutual pushing with the piston rod 26

Title: Bathroom floor heating unit
Inventor: YAMAO YUTAKA
IPC: F24D3/08
Filed: 1986-05-14
Abstract: PURPOSE:To make it possible to carry out bathroom floor heating safely and economically by connecting a bathtub to a heat source and providing a hot water storage tank assembled in a circulation pipe at a washing place, and radiating heat of hot water circulating within a circulation pipe by means of a pump. CONSTITUTION:At the time of additional heating of hot water within a bathtub 1, hot water flows from the bathtub 1 into a hot water storage tank 6 via an outgoing pipe 3a of a circulating pipe 3, and radiates heat to the floor surface 5 of a washing place. The radiated hot water passes through the outgoing pipe 3a of the circulating pipe 3, and is heated by a heat source 2, then passing through a return pipe 3b and again returning to the bathtub 1. Thus, by carrying out repeatedly such forced circulation, the floor surface 5 of the washing place is warmed by the heat radiation of hot water passing the inside of the heat storage tank 6, and hence comfortable bathing can be performed. Thus, the floor heating is carried out by utilizing heat of circulating hot water between the inside of the bathtub 1 and the heat source 2, it is unnecessary to provide a heat source exclusively used for floor heating and piping equipments exclusively used therefor, but it is possible to carry out the bathroom floor heating safely and economically.

Filed: 1984-05-29
Abstract: PURPOSE:To improve the quick responsiveness of the hydraulic turbine speed as well as the stability when an alliance system is changed to a single system, by providing a low pass filter to a feedback circuit for generator output to eliminate the power oscillation component. CONSTITUTION:A generator 1 is operated in parallel to other generators, and the speed signal 2 of the generator 1 is compared with a target speed setting signal 3. Then a deviation of this comparison is supplied to a correction circuit 7. While the output signal 4 of the generator 1 is compared with a target output setting signal 5, and a deviation of this comparison is applied to the circuit 7 through a speed regulation factor setter 6. The circuit 7 compensates the gain and delay of a phase to regulate automatically the revolving speed of a hydraulic turbine 9 to a target level. In this case, a filter 11 is put into a feedback part for generator output to eliminate the frequency components higher than the power oscillation frequency. Then the signal 4 is compared with the signal 5 through the filter 11. Thus the power oscillation component is eliminated and the stability is secured for the turbine speed.
