Abstract: PURPOSE:To reduce a clearance between a base region and an isolation region by forming reverse conduction type first regions to the surfaces of all island regions except the base region. CONSTITUTION:An epitaxial layer 22 and a buried layer 23 are shaped onto a substrate 21, and an isolation region 24 is formed while penetrating the epitaxial layer 22 so as to surround the buried layer 23.

Abstract: PURPOSE: To make the promotion of economy of energy, by means of controlling a delivery flow rate of the variable flow hydraulic pump in accrdance with a required flow rate.  
     CONSTITUTION: A piston rod 5 of a control cylinder 4, having a piston 3 made a displacement by a rocking lever 2 for around a fixed point 1, is slidably linked.

Title: Afc device
Inventor: KUROSAWA NAGAAKI
IPC: H04B3/04
Filed: 1980-06-25
Abstract: PURPOSE:To prevent tuning performance at a weak electric field from being deteriorated, by controlling an AFC circuit through the use of an AGC signal at the reception of interferred station at a strong field. CONSTITUTION:If a interference station having a strong electric field is present, an output voltage VAGC of an AGC signal detector 9 lowers and a transistor (TR)Q1 of an AFC circuit 10 is nonconductive. When the TRQ1 turns off and the collector voltage increases, a TRQ2 at the next stage is conductive. Thus, a resistance R4 is grounded, the AFC voltage of the AFC circuit 10 is attenuated with the resistance R4 and the AFC width is reduced. Thus, no AFC signal is affected at the interference station and it can be eliminated through the selective performance of an intermediate frequency amplifier 5 and the preoduction of noise can be avoided.

IPC: A62C35/68
Filed: 1990-03-30
Abstract: PURPOSE:To reduce the pressure drop of flow when a valve is opened by providing a seal material facing the inner face of a valve disc across a back pressure space, a seal material adapter by which the brim of the seal material is fixed on the valve disc, and a valve seat facing the outer face of the seal material. CONSTITUTION:When a secondary pipe 34 is filled with water and reaches a specified pressure, a pressure switch PS on a pressurized air reservoir is turned off so that a control board is brought into action to stop a pump 21. Then, when closed type sprinklers 40 are opened, fire extinguishing liquid in the secondary pipe 34 is spouted from the sprinklers 40. Consequently, the pressure in the pressurized air chamber drops causing the pressure switch PS to be turned on so that the control board is brought into action to start the pump 21. Therefore, the fire extinguishing liquid W in a water tank 22 is pressurized and sent to the secondary pipe 34 and spouted from the sprinklers 40 which are open. A flow detecting hole 4 is opened when a self-sealing type valve 20 is opened, and the fire extinguishing liquid enters an alarm pipe 3 to turn on a switch, so that an alarm device put into operation and an alarm is issued.
