Title: Apparatus for preventing headlamp from flickering
Inventor: NAKAYAMA FUJIO
IPC: B60Q1/14
Filed: 1983-05-02
Abstract: PURPOSE:To enable flickering of a headlamp to be suppressed that is used in an automobile having a electric power consuming apparatus such as a fine particle burning apparatus, etc., by changing power consumption to increase or decrease progressively by a dummy resistor. CONSTITUTION:An ECU13 changes switch circuits 15, 16 to (b) sides to turn an audio signal OFF and to send a signal to a comparator 35 before a relay 12 is magnetized if the reproduction timing for a trap 2 is judged when a headlamp is lit. The output of a square wave oscillator 31 is conducted via a voltage control variable gain amplifier 32 into a control amplifier 29, and the output of a power amplifier 20 is sent to a dummy resistor 28. On the other hand, by a negative output of a comparator 35, the output voltage of an operational amplifier 33 is increased progressively by a CR time constant to increase the amplification degree of the amplifier 32, and when the power consumption of the resistor 28 increases to the power consumption of a heater 9, the ECU13 changes the switch circuits 15, 16 to pass electric current to a heater 9. Thus the significant change in the power consumption would not occur and therefore the headlamp can be prevented from flickering.

IPC: C23C16/44
Filed: 1979-06-19
Abstract: PURPOSE:To provide graphite having excellent anisotropy by a method wherein electrostatic potential is applied between a conductive substrate installed in the atmosphere of thermally decomposed hydrocarbons and its counter electrode so that graphite generated by the thermal decomposition is deposited on the substrate surface in the presnece of weak electric field. CONSTITUTION:In a process for providing thermally decomposed graphite from hydrocarbon gas as raw material, an electrostatic potential is applied across a conductive substrate installed in an atmosphere of thermally decomposed hydrocarbons and its counter electrode. This allows generated carbon by the thermal decomposition to deposit on the substrate surface facing the electrode, in a 5-500V/cm weak electric field. The method provides highly orientated highly anisotropic, generated graphite by thermal decomposition of hydrocarbon at relatively low temperatures.

And, in a state that operating voltage is fed, a photoelectric surface 15 is irradiated with uniform light, and variable resistances VR1-VR4 are adjusted so as to cause each electric current securable from each of divided dynodes 11-14 to be equalized. And, supposing that each of currents I1-I4 flow into each of these dynodes 11-14, the output V1-V4 obtained out of ammeters A1-A4 is amplified at amplifiers 40a-40d, converting it into digital signal with converters 41a-41d, and it is once taken into a memory 42. A microcomputer 44 displays an incident position on an X-Y display 45. With this constitution, sensitivity by positions of the photoelectric surface and these dynodes and ununiformity in a multiplication factor can be compensated, thus a highly accurate incident position is detectable.

Title: Self oscillation semiconductor laser system
Inventor: SHIMOYAMA KENJI
IPC: H01S5/00
Filed: 1999-03-23
Abstract: PROBLEM TO BE SOLVED: To enable stable self oscillation even in high-temperature ranges by sandwiching at least part of both the sides of a second clad layer between low-refractive index current block layers the refractive index of which is lower than that of the clad layer. SOLUTION: Low-refractive index current block layers 114 are so formed that at least part of both the sides of a second clad layer 110 of second conductivity type is sandwiched between them. The refractive index of the low- refractive index current block layers 114 is reduced to a value lower than the refractive index of the second clad layer 110 of the second conductivity type sandwiched between the low-refractive index current block layers 114. This actual refractive index guide structure allows waveguide loss and ridge passage resistance to be reduced and thus threshold current, operating current, and operating voltage can be reduced. As a result, current spreading direct under the low-refractive index current block layers 114 can be reduced.  Thus, reduction in amount of saturable absorption due to temperature rise can be reduced and self oscillation can be sustained even at high temperature.
