Title: Voltage current conversion circuit
Inventor: KARUBE TOSHIKAZU
IPC: H03F3/45
Filed: 1997-03-17
Abstract: PROBLEM TO BE SOLVED: To set mutual conductance by means of an electric signal from outside by controlling a resistance value control signal and changing a resistance value through the use of a resistance value varying means for the feedback resistance of the differential amplifier of an input stage. SOLUTION: When the voltage applied to an input terminal 8 is called Vin, the resistance value of a resistor 2 is called R1, the resistance value of a resistor 7 is called R2, the resistance value of a resistance value varying means 5 is called R3, the emitter voltage VE of an npn-transistor 1 is given by VE=(R2+R 3)Vin/R2 and the current I flowing in the resistance R1 is given by I=VE1/R 1=(R2+R3)Vin/R1.R2. When the current amplification rate of the npn-transistor 1 is set to be α, the output current Iout of an output terminal 9 becomes Iout=α(R2+R3)Vin/R1.R2 and mutual conductance gm becomes gm=α(R2+R3)/R 1.R2. Since the resistance value R3 is decided by the control signal VG, mutual conductance gm is controlled from outside.

Abstract: PURPOSE:To read a display correctly and to recover electric power of a portable power supply and to display with high brightness for a long time by providing the time for putting out lights shorter than the lighting time for the prescribed interval in the case of driving a display section. CONSTITUTION:When a display mode is static, a driving section 2 provides the time for putting out lights shorter than the lighting time during the prescribed interval in the case of driving a display section 1. For instance, during the driving section 2 repeats scanning of transferring dot information of display data existing in the row to the display section 1 scanning successively 16 rows, display data is invalidated for 0.5sec. every 4.5sec. in which dot information of display data selected is transferred, and the display data is displayed with a period of 5sec. Since it can be performed by lengthening the lighting time to increase brightness in each scanning, putting out lights and brightness variation can be controlled independently. Also, if necessary, voltage of a power supply section 3 is monitored, and brightness is increased by widening scan pulse width according to reduction of voltage.

Filed: 1985-03-29
Abstract: PURPOSE:To facilitate cold starting even upon occurrence of abnormality in the temperature sensor while to prevent degradation in operationability after warming by varying the level of an electrical signal for compensating the abnormality with correspondence to the operating condition after starting. CONSTITUTION:Upper and lower limit temperature signal levels V2, V1 for deciding the abnormal function of temperature detecting means comprising a resistor 9, a temperature-sensitive element 7, etc. are previously stored in the memory 27 of control unit 1 and compared with a temperature signal level VSD read in through the temperature detecting means.

Filed: 1996-03-21
Abstract: PROBLEM TO BE SOLVED: To make it possible to dynamically control the double refractive index within a double refraction region even with an inline type of small connection loss and even after production, by irradiating an optical transmission line including a core and clad with X-rays in the direction crossing the core over a prescribed length thereof. SOLUTION: A coating 3 is first removed over a region 10A of the optical fiber 10 inclusive of the core 1, the clad 2 and the coating 3 and the optical fiber is etched by an aq. hydrofluoric soln. until the prescribed outside diameter is attained. The core 1 in the region 10A is thereafter irradiated with the X-rays 5 from a transverse direction via a mask 4, by which the double refraction region 1a is formed in the core 1 in the region 10A. The formed double refractive core region 1a has the asymmetric distribution of the refractive index inside and the asymmetry of the refractive index distribution is further increased by the irradiation with the light. The increase disappears if the irradiation with the light is ceased. Then, the deflection characteristic within the small region is easily controlled by irradiating the inside of the small region 10A with the light.
