Title: Semiconductor laser and driving method thereof
Inventor: HARA TOSHITAMI
IPC: H01S5/042
Filed: 1990-11-19
Abstract: PURPOSE:To enable a semiconductor laser to output laser rays stabilized in wavelength and output level by a method wherein currents injected into current infection regions are modulated synchronous with each other, and the overall length of an optical path is prevented from deviating from a set value by lambda or above. CONSTITUTION:Two or more current injection regions are provided including an active region section A, and provided that a current injection region is composed of a phase adjusting section P and an active section A, as an injection current to the active section A is made to change corresponding to modulating signals, an injection current to the phase adjusting section P is shifted in an opposite direction to synchronize with the injection current to the active section A. By these processes, the overall length of a light path is so set as not to deviate from a set value where an excellent output power can be obtained by lambda or above at modulation. A circuit, which is used for the high speed modulation of an LD to allocate the same current to several sections, is used as a circuit which enables currents injected into the sections A and B to be modulated synchronizing with each other. By this setup, a semiconductor laser can output laser rays stabilized in wavelength and output level even if the laser is directly modulated.

Title: Power window drive control device
Inventor: KUMAGAI KATSUHIDE
IPC: B60J1/00
Filed: 1993-12-16
Abstract: PURPOSE:To enhance the catch detecting function by converting a waveform from a pulse encoder attached to a motor into a triangular waveform, and by comparing the same with a smoothened reference waveform. CONSTITUTION:Upon catching, the speed of a motor 20 lowers, and accordingly, the pulse width of waveforms delivered from a pulse encoder 44 becomes large. Accordingly, the voltage of triangular waveforms formed by a waveform converting circuit 50 gradually increases at a constant variation rate. Then, the triangular waveforms are smoothened by a smoothing circuit composed of a resistor 66, a capacitor 70, an amplifier 68 and the like, and accordingly, the voltage of a reference waveform is also raised. In this case, since the voltage rise-up variation rate of the reference waveform is smaller than that of the triangular waveforms, the voltage of the triangular waveforms is higher than that of the reference waveform. Further, a difference detecting comparator 62 delivers a high level signal to a motor operation logic circuit 42 so that the motor 20 is stopped and reversed. With this arrangement, the detection can be made with a high degree of accuracy, and a catching load can be reduced. Further, it is possible to eliminate the necessity of limitation to the detection processing speed.

Title: Liquid level detector
Inventor: TSURUOKA MICHIHIKO
IPC: G01F23/22
Filed: 1988-12-15
Abstract: PURPOSE:To prevent a detecting element including a temperature sensing element from being corroded with the liquid of an object to be detected, etc., and also, to simplify a structure by attaching the temperature sensing element for outputting a temperature sensing signal corresponding to its own temperature to the outside surface of a side wall of a container including a liquid in the inside and detecting the liquid level of the liquid, based on the temperature sending signal. CONSTITUTION:On the outside surface of a side wall 1a of a container 1 in which a liquid 2 is housed, a temperature sensing element 3 for outputting a temperature sensing signal 3a corresponding to its own temperature to a circuit part 5 is stuck by a heat conductivity type adhesive 4. In the case when the inside surface opposed to a temperature sensing element 3 fitting part of the container side wall 1a is brought into contact with the liquid 2, and in the case when the inside surface is brought into contact with the gas of the upper part of the liquid 2, diffusion coefficients of heat diffused to the inside of the container 1 from the temperature sensing element 3 heated by a heating means 18 are difference from each other, therefore, in accordance with the liquid level of the liquid 2 in the container 1, the temperature of the temperature sensing element 3 is varied. Accordingly, by the temperature sensing signal 3a from the temperature sensing element 3, the liquid level can be detected. In this case, since the temperature sensing element 3 is attached to the outside surface of the container and is not brought into contact with the liquid 2 and gas thereon, it is scarcely corroded.
