Title: Apparatus for trimming semiconductor circuit
Inventor: KAMATA TADASHI
IPC: H01L27/04
Filed: 1985-07-23
Abstract: PURPOSE:To obtain a trimming unit which can easily control the trimming of the resistance value for enabling the adjustments of the circuit constant, the oscillation frequency of an oscillator and the D/A conversion properties, by supplying a trimming pulse signal from a pulse generator to an element to be trimmed, for example, a resistor formed of polysilicon containing a high concentration of impurities. CONSTITUTION:A resistive element 11 is formed of a thin film of polysilicon resistor containing a high concentration of impurities. The thin-film resistive element 11 is provided with a narrow portion 101 approximately in the middle in the direction along which electric current flows, so that electric current is concentrated in this narrow portion 101. Pads 20 and 22, and pads 21 and 23 are short circuited for example by contacting probes 25 and 26, respectively. A trimming pulse generator 27 is inserted between these probes 25 and 26. Accordingly, when the pulse generator 27 is driven with the probes 25 and 27 contacted with the pads 20-23, a trimming pulse voltage is provided to the resistive element 11 to be trimmed.

Title: Gain controller
Inventor: FURUKAWA TOSHIHIKO
IPC: H04N9/68
Filed: 1984-07-31
Abstract: PURPOSE:To facilitate the adjustment, to stabilize the gain and to prevent the deterioration of contrast by providing a gain control circuit installed at each video signal and a calibrating circuit for calibrating the gain so as to obtain an output at the same level as that of the gain control circuit to be use as a reference to the calibrating signal inputted commonly to each gain control circuit instead of a video signal in a blanking period. CONSTITUTION:Calibrating circuits 7g and 7b change values of input resistances Rg and Rb until output signal voltages of gain control circuits 3g and 3b coincide with a reference value. As a result, such calibration is executed that resistance values of the input resistances Rg and Rb are caused to coincide with the resistance value of an input resistance Rr. Consequently, gains of all gain control circuits 3r, 3g and 3b coincide before a vertical scan period starts. Moreover, the resistance value R of a photoconductive cell, which comprises photoconductive couplers 11g and 11b and is necessary for the coincidence, is stored in an analog memory circuit 10. A contrast is adjusted by changing a reference DC voltage VC of a contrast adjusting reference voltage source 8.
