Title: Liquid pressure device of energy collection type
Inventor: TAMADA TOSHIRO
IPC: F03B17/02
Filed: 1991-02-27
Abstract: PURPOSE:To enhance the energy efficiency of a liquid pressure device by effectively utilizing the compression energy which the high pressure liquid bears. CONSTITUTION:Pressure vessels 10, 12 are connected through cylinders 16, 42 and a link device 64, and to these cylinders 16, 42 a solenoid-operated direction changeover valve 30 and a pump 32 are connected. The pressure vessel 12 accommodates high pressure liquid while the other 10 contains liquid with normal pressure, and in the situation where a piston 62 is in the sunk position, the direction changeover valve 30 is switched to the upper position, and the pump 32 is operated. The cylinder 16 is chiefly driven by the working force of the other cylinder 42 given by the pressure of the pressure vessel 12 to pressurize the liquid in the pressure vessel 10. The power boosting factor of the link device 64 increases with pressure sink in the pressure vessel 12, and the cylinders 42, 16 continue operating even though the pressure in the pressure vessel 12 sinks below the pressure in the pressure vessel 10. Thus the energy in the pressure vessel 12 can be utilized effectively.

Title: Welding procedure for deformed bar
Inventor: YOSHIMURA HARUO
IPC: E04G21/12
Filed: 1990-03-09
Abstract: PURPOSE:To facilitate the whole welding operation without inserting joints, etc., between butted deformed bars at the time of assembly by mounting a joint curved along the outside shape of the deformed bars from the rear side of the deformed bars and welding the deformed bars toward this joint. CONSTITUTION:The joint 4 is pressed to the butt parts of the bars 2 set in a prescribed root gap from the rear side of the direction where welding is executed. This joint 4 is subjected to spot welding, etc., between the joint and the bars 2 and is thereby tack-welded to the bars 2. The butt parts of the bars 2 covered with the joint 4 on the rear side are connected by gas-shielded arc welding from the front side. The bars 2 are, therefore, welded to each other by pressing the joint 4 to the bars 2 set in the root gap and by using the arc welding, etc. The operation is thus extremely easily carried out.

Title: Security device
Inventor: ITO KUNIYOSHI
IPC: G08B13/00
Filed: 1988-03-11
Abstract: PURPOSE:To reduce cost and to improve operability by providing a set switch and a means for setting selectively a crime prevention mode and a crime prevention mode with going-out permission in accordance with the number of times of operation of said set switch. CONSTITUTION:When a set switch 52 is brought to ON-operation once, a transistor 32 becomes OFF, a series circuit of abnormality detecting switches 1a, 1b,...1n in becomes effective, and a crime prevention mode is set. When the set switch 52 is brought to ON-operation again, an output of a timer circuit 45 becomes logic '1' only for a prescribed time. As a result, the transistor 32 becomes ON, and even if the abnormality detecting switch becomes OFF, an alarm sound is not generated. That is, a crime prevention mode with going- out permission is set. In such a way, since the crime prevention mode and the crime prevention mode with going-out permission are set selectively at every ON-operation of the set switch 52, one set switch will suffice, and the cost is reduced. Also, the operation is simplified and the operability is improved.

IPC: H04W84/02
Filed: 1991-02-28
Abstract: PURPOSE:To offer a radio selective call receiver which informs the fact that a reception message estimated as the one not being confirmed by a user is present periodically. CONSTITUTION:When call information by the flash of a LED 9, etc.. by the reception of an address signal that coincides with its own address and display by the LCD 13 of the reception message are performed, such display is automatically reset. A CPU 6 defines a message received this time and stored in a RAM 5 as an unconfirmed message. The CPU 6 issues the information representing the presence of the unconfirmed message in a type distinguishable from selective information by a method of flashing the LED 9, etc., at every prescribed time by a timer 16 while the unconfirmed message is being stored in the RAM 5. When the readout operation of the message is performed at a switch part 14, and the unconfirmed message stored in the RAM 5 is re-displayed on the LCD 13, and also, a confirming operation is performed, the CPU 6 defines the message as a confirmed message.
