Title: Exhaust gas sensor
Inventor: KOMATSU KAZUYA
IPC: G01N27/12
Filed: 1987-05-26
Abstract: PURPOSE:To improve the holding strength of the sintered body of a metal oxide semiconductor, by selecting the thickness and the clearance of a flame coating film. CONSTITUTION:A sintered body 8 of a gas sensitive metal oxide semiconductor is contained in a cavity 6, which is provided in a heat resisting insulating substrate 2, with a gap being provided. The sintered body 8 is fixed to the cavity 6 with a ceramic flame coating film 24. For the flame coating film 24, any of fine or porous material can be used. In order to prevent the decrease in response characteristic of a sensor due to the flame coating film 24, it is desirable that flame coating is performed only on a part of the surface of the metal oxide semiconductor. When the sintered body 8 is contained in the cavity 6, the gap having a certain size is required in consideration of errors in sizes of the sintered body 8 and the cavity 6, difference in thermal expansion coefficients of both parts and the like. The radio between the width of the gap, i.e., the clearance and the thickness of the flame coating film 24 is important. When the ratio is made to be 0.6 or more, cracks are not yielded in the flame coating film 24, and the sintered body 8 can be sufficiently held in the cavity 6.

Title: Starting device for discharge lamp
Inventor: OCHI MASAFUMI
IPC: H05B41/16
Filed: 1977-10-28
Abstract: PURPOSE:To minimize the voltage applied across the circuit through the suspension of triggering of a semi-conductor switching element by using an impedance voltage induced across the secondary coil of a stabilizer after lighting of a discharge lamp with the actuation of an impedance stabilizer. CONSTITUTION:When the power is turned on, capacitors Cp30 and C30 are charged through a diode D31. When the terminal voltage of the capacitor C30 reaches the breakover voltage of a trigger element Tr30, a thyristor T30 conducts to allow the capacitor C30 to discharge electricity. Thus, a pulse voltage is induced across the secondary coil of a choke B30 to light a lamp L30. After lighting, a lamp current flows to generate an impedance voltage across the choke B30 which charges the capacitor C30 in the reverse direction through a diode D32 and a resistor R33. Accordingly, the thyristor Tr30 fails to be triggered so that no pulse voltage is developed while the lamp is on.

Title: Optical coupling type relay circuit
Inventor: MATSUMOTO TAKESHI
IPC: H03K17/78
Filed: 1988-05-26
Abstract: PURPOSE:To obtain the linearity of output by fast switching by connecting a series circuit of a control transistor(TR) and a phototransistor between the drain and gate of an output MOSFET and coupling the phototransistor and a light emitting diode optically with each other. CONSTITUTION:When an input signal is applied between input terminals 8a and 8b, the light emitting diode 1 generates a light signal to turn on the phototransistor(PT) 6 and a load current flows to a load 10. This current flows from a 2nd control TR 4 through the PT 6, a 1st control TR 3, and a resistance 5 and is also shunt to the capacity between the gate and source of an output MOSFET 7, which is charged fast, so the gate-source voltage rises abruptly. The FET 7 is turned on speedily. A photodiode PD array 2, on the other hand, generates a photoelectromotive force to turn off the TRs 3 and 4 and the current from a DC power source 9 to the load 10 does not flow through the PT 6 any more, but the photoelectromotive force of the PD array 2 is applied between the gate and source of the FET 7, which is held on, so that the linearity of the output is held.

Abstract: PURPOSE:To reduce the operation man-hours of checking and adjustment and to reduce cost and operation errors so that high image quality is maintained by constituting the above system in such a manner that a copying operation can be executed even in a self-diagnosis mode. CONSTITUTION:This system consists of a self-diagnosis mode control section 01 which executes checking, adjusting, etc., of a recorder body 04 in the self- diagnosis mode, an ordinary mode control section 03 which drives the recorder body 04 in an ordinary copy mode, and a state control section 02 which transfers the state between the self-diagnosis mode and the ordinary copying mode. The checking, adjusting, etc., of the recorder body 04 are executed by executing the proper state transition between the self-diagnosis mode and the ordinary copying mode. The copying operation can, therefore, be executed by utilizing the various modules formed for the ordinary copying mode. The ordinary copying mode is thereby executed without separately forming the module to be exclusively used and the maintenance cost is reduced. The maintenance of the high image quality is thus enabled.

Abstract: PURPOSE:To ensure the display for the water, wind and school of fish by combining the electronic circuit producing the time difference and plural units of simple light emitting devices, thus realizing a long life time of the device as well as increasing the luminance. CONSTITUTION:Pulse A generated from reference time generator 1 is supplied to time difference generator circuit 2. Circuit 2 has the output terminals of five circuits, and thus the output signals shift to C from B and then to D from C with supply of every unit of pulse A. After reaching final F, the output signal returns to B to repeat this action. The time from B to F can be varied easily by changing the cycle of generator 1. Then the waveform shaping is given to measuring ultrasonic wave G through amplifier 5 to obtain voltage H. This voltage H plus the output signals from C to F supplied from circuit 2 are made to pass AND circuit 3, and as a result the output of circuit 3 emerges only to the circuit of the period during which the ultrasonic wave exists. Thus the light emitting device 4 connected to circuit 3 is actuated.

Abstract: PURPOSE:To eliminate the effect of manufacturing variation on a threshold voltage even for a region where a drain-source voltage is low by using a MOS transistor (TR) at the unsaturated region and using the MOS TR and an amplifier to form a negative feedback loop. CONSTITUTION:A source 4 of an N-channel MOS TR 1 of enhancement type is connected to common via a resistor 5 and an output terminal of an operational amplifier 6 having a high impedance is connected to a gate 3. Further, a non-inverting input of the amplifier 6 is connected to a constant voltage terminal 7. as a resistor 5, a resistor with less manufacture variation and not affected by a current or voltage is selected. When the MOS TR 1 is operated at the unsaturated region, even when the drain voltage is fluctuated, the voltage of the terminal 7 and the source 4 is equal. Since the potential of the source 4 is constant, only a prescribed current flows to the resistor 5, only a current of VR/R (VR: voltage of the terminal 7 and R: resistance of the resistor 7) flows independently of the drain voltage in the current path from the drain 2 to common.
