Title: Power supply circuit for power amplifier
Inventor: OZAWA AKIO
IPC: H03F1/02
Filed: 1979-03-13
Abstract: PURPOSE:To decrease the collector loss by giving the sequential and stepped change to the collector application voltage of the power transistor in accordance with the output signal voltage level. CONSTITUTION:The emitters of complementary push-pull power transistors Q1 and Q2 forming the final output step of the power amplifier are connected to the output points via resistances R1 and R2 to give driving to speaker RL functioning as the common load. This output signal voltage VOUT is applied to comparators 1-6 to be compared with each reference voltage. Then comparators 1-6 generate control signals S1-S6 when the absolute value of VOUT is larger than that of referencc voltage B, thus opening and closing switching means SW1-SW6. Thus switches SW1-SW6 are opened and closed according to the level change in case VOUT has variation in order to change the collector application voltage of transistors Q1 and Q2.

IPC: B23K35/14
Filed: 1982-02-27
Abstract: PURPOSE:To adhere two members having different coeffts. of thermal expansion in such a way as not to generate cracking, cambering, etc., by containing plural granular materials having uniform shapes and having the quality dissimilar from the quality of the metallic solder in said solder of the adhered surfaces of said members.

Filed: 1987-02-10
Abstract: PURPOSE:To restart the transmission of picture information interrupted not through page boundary operation by giving an advance notice to a receiver with prediction if transmission time for one picture information exceeds the limit time. CONSTITUTION:A communication time counter means 1 starts counting when communication is started and if a count 11 is going to exceed a maximum communication time specified by a communication system, a time exceed prediction detection means 2 outputs a time excess alarm signal 21 to a communication means 3.

The communication control means 3 connects the communication and sends the page consecutive display signal to the facsimile receiver to command the restart of the picture information reception and restarts the transmission of picture information. Thus, one original information is sent over plural number of communication processings without page boundary operation by the receiver.

Abstract: PURPOSE: To utilize the rotation of a vane wheel as an energy source such as a power, electricity, etc. by providing the vane wheel into a water tank and injecting air from the bottom of said tank to rotate the vane wheel by the buoyance of the air.  
     CONSTITUTION: Gaseous fluid compressed by a compressor 7 is injected into a storage tank 1 through a gas circulation port 4 and a check valve 5 provided at the bottom of said tank 1. The injected gaseous fluid rises in the tank due to the difference of the specific gravity from that of the liquid in the tank 1. This energy rotates a vane wheel 2 provided in the tank 1 and can be taken out from a shaft 3 of the vane wheel 2 as power or electricity. The bubbles reach the top of tank and are returned to the compressor 7 through the gas circulation port 4 at the top of the tank and a gas circulation piping 6 thereby enabling continous utilization of the buoyance of gas to the liquid which rotates the vane wheel for generation of power or electricity.
