Filed: 1982-06-09
Abstract: PURPOSE:To discriminate an optical receiving signal stably at all times, by giving the optical receiving signal to one of positive and negative input terminals of a comparator and giving the signal to the other terminal of the positive and negative input terminals via a delay circuit. CONSTITUTION:The optical receiving signal is given to the positive input terminal of the comparator 11 via an input resistor 14 and to the negative input terminal via an input resistor 16 after the signal is given for a delay of a prescribed time via a delay circuit 15. Further, an output signal of positive and negative output terminals of the comparator 11 is fed back positively via resistors 12 and 13 to the positive and negative input terminals respectively. Thus, the detection and discrimination of the optical receiving signal is attained stably in following to a rapid fluctuation of the optical receiving signal without being subject to the adverse effect such as temperature drift or the like.

Title: Resistor
Inventor: TAKASHIMA HISAHIRO
IPC: H01C7/00
Filed: 1997-04-16
Abstract: PROBLEM TO BE SOLVED: To prevent a resin protective film layer from being separated and to ensure a stable quality of a resistor by a method wherein the precoating layer having the same or larger pattern as or than that of the resin protective film layer is formed. SOLUTION: A precoating glass layer 25 has the same pattern as that of a resign protective film layer 27 or a pattern larger than that of the layer 27. Thereby, it is eliminated that the layer 27 is directly formed on an upper surface electrode layer 23 and the adhesive strength of the layer 27 is enhanced, whereby the formation of the layer 25, which is formed of the pattern, has an action to say that a plating solution at the time of plating is reprevented from intruding into a resistor, the layer 27 can be prevented from being peeled from the layer 25 and the resistor of stable quality can be realized. Moreover, the layers 25 and 27 have similar colors Thereby, the formation of the layers 25 and 27 has an action that even in the case where the layer 25 is formed of the pattern larger than that of the layer 27, the resistor, which is good also in the quality of its appearance, can be realized.

Title: Inverter and solarlight power generation system
Inventor: KURIOKA HIDENORI
IPC: H02N6/00
Filed: 1996-04-19
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of a harmonic by inhibiting the distortion of an output current, by selecting whether or not zero-voltage switching by a zero-voltage circuit is conducted in response to the pulse width of pulses for controlling the switching of an inverter circuit. SOLUTION: In an inverter, a selecting circuit 24 selecting whether or not the zero-voltage switching of an inverter circuit 2 by a zero-voltage circuit 3 is performed on the basis of pulse width detected by a pulse width detector 11 of pulses TPWM from a PWM timing generating circuit 6 and a reference pulse width Tsw is installed. Zero-voltage switching is conducted when the pulse width of PWM pulses TPWM exceeds a reference pulse width Tsw by controlling first and second switching circuit 12, 13, and zero-voltage switching is not executed when pulse width is narrowed and the pulse width of PWM pulses TPWM reaches reference pulses or less. Accordingly, since zero-voltage switching is not performed for a period when distortion is generated at an output voltage, the distortion of an output current can be improved, and the generation of a harmonic can be prevented.

Abstract: PURPOSE:To maintain normal control of a line pressure during gear shifting at a low water temperature period by a method wherein during a low temperature period in which the temperature of cooling water of a prime mover is below a set value, actuation of a line pressure correction amount computing means is stopped, and a line pressure correction amount is prohibited against variation by means of a learning control prohibiting means. CONSTITUTION:Based on signals from an input and an output rotation sensors, an inertia phase time measuring means measures a time in which the gear ratio of a speed change gear mechanism is changed, namely an inertia phase time during gear shifting. A line pressure correction amount is determined by a computing means according to a difference between the measurement and a target value, and a line pressure by a line pressure regulating means is corrected. In which case, during a low temperature period in which an engine cooling water temperature detected by a water temperature sensor is below a set value, actuation of a line pressure correction amount computing means is stopped by a learning control prohibiting means, and a line pressure correction amount is prohibited against variation. This constitution prevents random control of a line pressure during gear shifting at a low water temperature period.
