Title: Output circuit for dc two-wire sensor
Inventor: MATSUMOTO AKIO
IPC: H03K17/945
Filed: 1988-11-30
Abstract: PURPOSE:To reduce the variance of residual voltage by providing a subtraction circuit to subtract the output current of an amplification circuit from the sum current of the base currents of a second transistor (TR) and a third TR, and canceling the base current itself of a second TR by the subtraction circuit. CONSTITUTION:The base current I4 of the TR Q4 flows into the TR Q5 of the amplification circuit. The output current I5 of the amplification circuit can be made to be I5=2I4 if the values of resistors R5, R6 are selected properly. At a node N, the subtraction of I7-I5 is performed, but if the above-mentioned expression is considered, it results in I7-I5=0. Accordingly, since all the sum current I7 of the base currents of the TRs Q1 and Q3 is canceled, the current to flow into an impedance element Z becomes zero. Accordingly, the output residual voltage VR comes not to be influenced by the base current of the TR Q1.

Filed: 1995-11-20
Abstract: PROBLEM TO BE SOLVED: To easily and momentarily grasp the outline of overall information in a visual way by serially or selectively controlling and lighting a continuous array part of each segment for analog indication. SOLUTION: A segment display part 23 at a lower row digitally indicates preset temperature by use of numeric values.

Filed: 1997-11-04
Abstract: PROBLEM TO BE SOLVED: To restrict a temperature rise of a double tube because of heat conduction from a high-temperature fluid and at the same time prevent a damage because of vibrations, by arranging a projection to face to a temperature pocket at the inside of an area which is the inside of an outer tube of a protecting tube and the outside of an inner tube. SOLUTION: A thermometer pocket vibration isolation 14 of a cylindrical projection of a height L of approximately 20 mm is set at a position inside of protecting tubes 11, 12, 13 and outside of a liner 5 by approximately 60-150 mm. A shift of a thermometer pocket 10 because of vibrations of a high-temperature internal fluid 4 is supported by the vibration isolation 14. The thermometer pocket is reduced in amount of bend, and a stress brought about at a fixed part of the thermometer pocket 10 is decreased to not larger than a stress breaking the fixed part of the thermometer pocket 10. The vibration isolation 14 can support the thermometer pocket 10 on a plane and therefore, a stress concentration at a contact part when the vibration isolation 14 comes in touch or collides with the thermometer pocket 10 is prevented.  Moreover, a temperature rise at a cap 8 and a pressure-resisting part of a washer 9 can be restricted when the protecting tubes 11, 12, 13 are enhanced in rigidity and the thermometer pocket 10 is reduced in sectional area.

Title: Safety device for gas burner
Inventor: ARAKI TAKAAKI
IPC: F23N1/08
Filed: 1988-11-29
Abstract: PURPOSE:To remove combustion products as warned, and eliminate maintenance inconvenience by carrying out cleaning alone when detecting a harmful gas component having a specified warning density lower than a stop density and halting the supply of gas to a burner when detecting a harmful gas component having a density high than the stop density latter. CONSTITUTION:The density of a harmful gas component such as CO produced by incomplete combustion detected by a gas sensor 36 is compared with a warning density. If a harmful gas component whose density is higher than a warning density is detected continuously three times and over, the CPU displays a warning that come cleaning time has arrived to remove combustion products, and resets the number of detection 'n' to 0, thereby returning control operation. If a cleaning warning is indicated, the CPU compares the harmful gas component detected by the gas sensor 36 with a stop density. If the harmful gas component whose density is higher than the stop density is detected continuously more than three time, abnormality indication will be made by a buzzer or the like. As a result, solenoid valves 22 go 24 will be closed respectively and after purging will be carried out for a specified time, thereby halting every control operation.
