Title: Gain control system of d/a converter
Inventor: ONO SHIGEAKI
IPC: H03M1/70
Filed: 1985-06-25
Abstract: PURPOSE:To perform high-accuracy gain control by an inexpensive circuit by adding a gain control voltage that a D/A converter for gain control outputs to a reference gain control voltage and using the addition output as a reference voltage for gain control over a D/A converter. CONSTITUTION:A digital input 11 for gain control is converted by the D/A converter 12 for gain control into an analog output, which is inputted to an adder 14. A reference gain control voltage generating circuit 13, on the other hand, outputs the reference gain control voltage to the adder 14. Then, the adder 14 adds the analog gain control output voltage to the reference gain control voltage and inputs the addition voltage to a D/A converter 16 as the reference voltage 15. Consequently, the digital input to the D/A converter 16 is outputted in the form of the analog output 17 after gain control.

Title: A supply-exhaust cylinder
Inventor: MIYAHARA SHINJIROU
IPC: F23L17/04
Filed: 1977-11-16
Abstract: PURPOSE: To prevent exhaust gas from being re-supplied and thereby to maintain goog combustion.  
     CONSTITUTION: An air stream flowing into the end of supply-exhaust cylinder B from outside flows along the inner surface of exhaust guide 7, passes vent 9 and is turned in the direction of exhaust port 5 by flow-turning plate 8, and then it is discharged outside again from cylinder B. By this, exhaust gas is always discharged in opposing the wind velocity exerted on cylinder B. For this reason, discharged exhaust gas is not pushed back to air-supply port 2 by the wind. Further, when there is no wind, the inside of vent 9 becomes negative in pressure due to the exhaust gas stream which flows to exhaust port 5 along the surface of stream-turning plate 8. Consequently, outside air is drawn into cylinder B via vent 9, and it is mixed with exhaust gas. Thus, the concentration of exhaust gas is diluted, so that the amount of exhaust gas supplied again from air-supply port 2 can be reduced practically to zero.

Title: Lead storage battery having device for stirring electrolyte
Inventor: TAKAHASHI KATSUTO
IPC: H01M2/38
Filed: 1983-07-27
Abstract: PURPOSE:To increase the life and improve the charging efficiency of a lead storage battery by equalizing the concentration of electrolyte by attaching a pressure control value to the top of the battery and providing a means of stirring the electrolyte after opening the pressure control valve when the internal pressure of the battery increases to a given level. CONSTITUTION:The original internal pressure of a lead storage battery is an atmospheric pressure. A pressure control valve 10 is closed. When the internal pressure of the battery gradually increases due to gas generation and becomes different from the internal pressure of a case 4, electrolyte 3 existing in the lower part of the battery flows through an inflow valve 5 into the case 3. When the internal pressure of the battery reaches 0.01kg/cm<2> or greater, the pressure control valve 10 opens. When the internal pressure of the battery becomes an atmospheric pressure again, the electrolyte 3 contained in the case 4 flows out through an outflow valve 8 into the battery. By repeatedly carrying out these processes, the electrolyte 3 of high concentration existing in the lower part of the battery is efficiently carried to its upper part and any stratification of the electrolyte 3 is prevented.
