Title: Pressing device for low pressure casting
Inventor: UOZUMI MINORU
IPC: B22D18/08
Filed: 1979-02-20
Abstract: PURPOSE: To ease the pressing force controlling of the captioned device and improve product quality by measuring the pressure in the spacing formed by the sprue pipe of the die bottom end, the connection port of a heat-retaining furnace and the molten metal level within a molten metal holding furnace and feeding the same back to an electromagnetic pump.  
     CONSTITUTION: A furnace body 1 is moved upward by a cylinder and a sprue pipe 6 is put into the connection port 3 of the body 1 so that it is contacted to the cavity lower plate 2 and is closely contacted by flange part 3b. When the molten metal for about 1 shot is replenished through a pouring cup 2 from a replenishing device and an electromagnetic pump 4 is let to start pressing according to the set signal of a pressing pattern generator 11, then the molten metal rises in the sprue pipe 6 and the spacing 3a between the sprue pipe 6 and connection port 3 becomes hermetic spacing, and this results in that the internal pressure thereof indicates the molten metal head in the pipe 6. This internal pressure is measured with a measuring device 9 and is transmitted to a controller 10 which in turn controls the electromagnetic pump 4 by way of an output variator 12, whereby the pressing is let to accurately conform to the pressing pattern over the entire casting process. When the output of the measuring device 9 becomes larger than a set value 15, a comparator 16 emits the molten metal replenishment stop signal 16.

Filed: 1985-02-03
Abstract: PURPOSE:To generate a transmission output reduction command signal automatically by comparing the driving signal of a motor that drives a variable capacitor that matches an antenna and transmitting side with a transmission receiving change-over signal. CONSTITUTION:A tuning driving circuit 1 responds to antenna tuning AT start pulse, and outputs a transmission output reduction signal PD to a transmitter 52 receiving the state of transmission of a transmitting receiving change-over signal TV from a transmitter receiver 52. An automatic antenna tuner 60 generates a tuning motor voltage signal MB by the signal TV through transistors Tr 65, 66 and drives motors 63, 63, 64 and changes the capacity of variable capacitors 61, 62 that constituted an antenna coupling circuit, and performs a tuning action. When the matching is made, Tr 65, 66 are made off, and the tuning action is stopped. When the circuit 1 detects that the signal MB was extincted earlier than the signal TV, the circuit extinguishes the signal PD and outputs a signal NT that indicates non-tuning state correspondingly.

Title: Electronic clinical thermometer
Inventor: OGAWA HIROSHI
IPC: G01K13/00
Filed: 1982-02-08
Abstract: PURPOSE:To perform an easy and high-precise adjustment, by notifying a displaying  means at a selecting time of an adjusting mode that, in case an output of an amplifying means is not within a given range, an adjustment is required. CONSTITUTION:A variable resistor 6 for a gain adjusting means for regulating an amplifying gain is connected to an amplifier 5. The output of the amplifier 5 is inputted  to an analogue/digital (hereafter called A/D) converter 7. The output of the A/D converter 7 is applied to a microprocessor 8. When a reference voltage V is applied from  a change-over switch 4, the microprocessor 8 decides that measurements provided by  the A/D converter 7 are an output of a reference resistor 2, and in case the reference  voltage V is not applied through the change-over switch 4, it decides that the measurements are an output of a temperature-sensitive sensor 1. If an error is produced while  an electronic thermometer is used for a long period of time, an adjustment is made as  follows. If change-over switches 3 and 4 are switched to a contact (b) side, the resistance value of the reference resistor 2 is applied to an amplifier 5 through the change- over switch 3, and thereby the amplifier 5 applies an amplifying output, correlative to  temperature based on the resistance value of the reference resistor 2 and a resistance value of a variable resistor 6, to the A/D converter 7. When the resistor 6 is needed to be regulated, a sound is produced from a buzer 10 to regulate the variable resistor 6 through hearing of the sound.
