Title: Liquid crystal driver checking circuit
Inventor: KOMATSU TAKAYUKI
IPC: G01R19/165
Filed: 1989-03-28
Abstract: PURPOSE:To check gradation processing functions of an LCD driver by comparing the output signal of the LCD driver by a differential amplifier and counting a clock only at the time when the output signal reaches a prescribed level. CONSTITUTION:First and second differential amplifiers 2 and 3 activate an AND gate 4 when an output signal 1 of the LCD driver is between an upper limit set voltage 8 and a lower limit set voltage 9 generated by D/A converters 11 and 12. An AND gate 5 acts to permit the input of a clock 6 to a clock counting circuit 7 only when the output of the gate 4 is in the active state. A GPU 10 reads the output value of the counting circuit 7 to detect the time of the signal of the LCD driver output stage outputted between the upper limit set voltage 8 and the lower limit set voltage 9. Thus, gradation processing functions (the output voltage and the time of the occurrence of the output voltage) of the LCD driver are simultaneously measured.

Abstract: PURPOSE:To form gate electrode width, a distance between a gate and a source, a distance between the gate and a drain, etc. minutely and accurately, and to give stable characteristics by utilizing a reactive ion etching method through which anisotropic etching is enabled. CONSTITUTION:A metallic film 3 in Ti, etc. as a gate electrode is formed on the whole surface of a GaAs semiconductor substrate 1, a resist 5 is applied, and said resist 5 is patterned to form a resist pattern 5a. A gate electrode G is shaped by dry-etching the metallic film 3 through an RIE method while using the resist pattern as a mask while a high resistance layer 2 in the surface of the substrate of the periphery of the gate electrode is etched only by fixed thickness after etching the metallic film 3. No side etching is generated at that time because anisotropic etching is enabled, and the gate electrode G in quite the same size as the resist pattern 5a is formed. The metallic film 3 is shaved off and a stepped section along the periphery of the gate electrode G is shaped, distances among a source region and a drain region and the gate electrode are set, and channel length is determined.

IPC: H03K17/04
Filed: 1989-03-29
Abstract: PURPOSE:To obtain a circuit quickly turned on/off by connecting a capacitor always charged whose capacitance is sufficiently large to an input of a transistor(TR). CONSTITUTION:Since a DC power supply is always applied between power supply terminals 2, 2, a light emitting diode 8a is lighted and a capacitor 18 is charged by an output of a photovolatile element 8b.

Thus, a stray capacitance Cg of a TR 9 is charged by a charge in the capacitor 18 and when the level reaches a threshold level or over, the TR 9 is turned on. When the input signal is lost, since the TR 15 is turned off, the photoconductive element 13b is turned off via the light emitting diode 13a, and since the charge in the stray capacitor Cg of the TR 9 is discharged via a resistor 12, the TR 9 is turned off.
