Title: Generator for gaseous methane
Inventor: MASUZAWA HIROYOSHI
IPC: C02F3/28
Filed: 1982-07-19
Abstract: PURPOSE:To generate gaseous methane at high efficiency, by providing a pump which sucks up the raw material in the body of a fermentation tank and a piping which returns the raw material discharged from the pump into the body of the fermentation tank and providing a heater in the mid-way of said piping. CONSTITUTION:When a pump 8 is started operation, the raw material sucked up through a suction pipe 6 is forced by pressure toward a discharge pipe 7, and the raw material is returned through the pipe 7 into the raw material in the body 1 of a fermentation tank. While the raw material passes in the pipe 7, the material is heated to the temp. slightly higher than 34-37 deg.C by a heater 9 and is circulated. Thus, even if the raw material is freshly replenished into the body 1, the temp. of the raw material can be maintained always at about 35 deg.C which is optimum for fermentation. Therefore, the temp. of the heater 9 is determined so as to attain the set value meeting the capacity of the body 1 in the stage of setting, and further the heater is automatically controlled by the signal of a sensor which detects the temp. of the raw material in the body 1.

Filed: 1977-10-20
Abstract: PURPOSE:To make it possible to obtain a high and stable resistance by interposing such means between a drive shaft and a piston as is operative to convert the rotational motions of the drive shaft into the linear movements of the piston. CONSTITUTION:When a shaft 10 turned, its cam groove 10C is also turned together so that a pin 4 engaging with the cam groove 10C is moved rightward while rotating along the cam groove 10C. As a result, a piston 2 moves rightward within a pressure chamber 1a so that the working oil in a chamber B flows into a chamber A  through an orifice 2a. At this time, the moving velocity of the piston 2 is reduced  by the flow resistance in the orifice 2a so that the rotational motions of the shaft 10  are subjected to shock absorption.

IPC: B61L3/12
Filed: 1979-10-01
Abstract: PURPOSE:To increase the S/N with increment of the reception level of the antenna provided on the vehicle, by distributing the loop side of the track side at a higher position than the loop side at the center side of the track in the vehicle communication. CONSTITUTION:The rectangular ground loop 3 is distributed along the directions of the tracks 2A and 2B, and one side 3a of the loop is positioned higher by a height H than the opposite side 3b. As a result, the coupling degree between the loop 3 and the antenna 4a mounted on the vehicle 1 becomes much larger than the coupling degree to the antenna 4b on the vehicle. The antenna 4b performs the information transfer to the ground loop provided at the side of the track 2B in the same positional relation. Accordingly, a pair of the antenna and the ground loop does not receive easily the signal disturbance from another pair of the antenna and the ground loop. As a result, the S/N can be increased for the communication signal during operation of both the up and down directions.
