Filed: 1990-02-19
Abstract: PURPOSE:To prevent stepping of a wiring layer and electrode part by detecting the end of etching of a second layer insulating film through detection of an adsorbed gas and by etching a first layer insulating film. CONSTITUTION:A second layer insulating film 12 is accumulated on a first layer insulating film 11, a resist is applied to the whole surface, a mask pattern 2 having an opening 3 is formed by the use of a photolithographic technique and thereafter the second layer insulating film 12 exposed in the opening 3 is subjected to an anisotropic etching. That is, an etching finish time is determined because an adsorption gas comes out at the point of time when the anisotropic etching of the second layer insulating film 12 is finished. Therefore, when etching conditions are changed in this case, the first layer insulating film 11 can be etched without doing damage to a substrate and without causing a side etching too much. Thus, a wiring layer and electrode can satisfactorily be connected.

Title: Digital filter with agc
Inventor: YAMAZAKI HAJIME
IPC: H03H21/00
Filed: 1981-03-18
Abstract: PURPOSE:To prevent overflow in the course of operations and to reduce the operation error, by connecting multipliers to the input side and the output side of a digital filter and increasing or reducing multipliers alpha1 and alpha2 while keeping the relation of alpha1=1/alpha2. CONSTITUTION:An input signal D1 is subjected to multiplication of D2=D1.alpha1 by a multiplier 2, and a resultant signal D2 is inputted to a digital filter 1. An increment detecting circuit 5 sets a signal B to 1 if the circuit 5 decides that the input signal D2 to the filter 1 is increasing, and a level detecting circuit 6 sets a signal A to 1 if the circuit 6 detects that the value of the input signal D2 is large enough to cause overflow in the course of operations of the filter. When signals A and B are 1 together, a multiplier generating circuit 7 reduces the value of the multiplier alpha1 and increases the value of a multiplier alpha2 in proportion to this reduction. An output signal D3 of the filter 1 is multiplied by the multiplier alpha2 by a multiplier 3 to obtain an output signal D4. If the amplitude level D2 of the input signal is very small, the level detecting circuit 6 sets a signal C to 1 to increase the value of the multiplier alpha1 and reduces the value of the multiplier alpha2.

Abstract: PURPOSE:To enable the peak charge phenomenon of a filter capacitor to be prevented from being generated when the capacitor is composed simplified with a light load, by turning input power to the filter capacitor, ON/OFF, and by preventing peak charge from being generated. CONSTITUTION:When a breaker 4 is turned ON, then the charging current of output generated from a rectifier 3 starts flowing to a filter capacitor 10 via a filter reactor 5 and an initial charging current limiting resistor 7. When the voltage of the filter capacitor 10 comes to a minimum working value, then gate signal based on continuous pulse 14 is applied to a peak charge suppressing thyristor 8 which is turned ON, and at the same time, an inverter 11 is worked. During the operation, when the voltage of the filter capacitor 10 comes to the set voltage of a voltage detector 9, then the thyristor 8 is turned OFF. As this result, input current from a stringing 6 is turned into slight current just via the initial charging current limiting resistor 7, and filter capacitor voltage is dropped.
