Title: Detection of end point of dry etching
Inventor: NAKAYAMA ICHIRO
IPC: H01L21/302
Filed: 1986-03-07
Abstract: PURPOSE:To enable the end point of etching to be detected accurately in the dry etching process of an SiO2 film by a method wherein the fluctuation in spectral intensity of fluorine atoms produced in plasma is detected. CONSTITUTION:Within a device wherein plasma is produced in a vacuum cham ber using fluorine base gas to dryetch a silicon oxide film coated on silicon or polysilicon primer, the fluctuation in spectral intensity of fluorine atoms produced in the plasma is detected to detect the end point of dry etching. In general, the SiO2 film etched by ion reaction only producing much F atoms themselves in the plasma, however, at the end point of etching process, the primer silicon or polysilicon react to the F atoms producing SiF4 to decrease the F atoms very rapidly. Through these procedures, end point of the dry etch ing can be detected accurately by monitoring the increase or decrease of F atoms.

Title: Driving circuit for semiconductor laser
Inventor: ENDOU TAKEMI
IPC: H01S5/062
Filed: 1983-03-26
Abstract: PURPOSE:To prevent a pattern effect based on the delay of the change of charge density, and to simplify the adjustment of an optical output waveform by making DC bias lower than a threshold value for a period of a low level in ''1'' of an input RZ pulse. CONSTITUTION:When a RZ pulse input signal of a period T is transmitted over a gate G1, an output from the gate is applied to a transistor TR1 as an input 1 as it is. The transistor TR1 and a transistor TR2 are differential-connected to form a current switch, and predetermined collector currents I1 are generated when the level of the input 1 is larger than reference voltage VR applied to the transistor TR2. On the other hand, an inversion output from the gate G1 is delayed only by the half period T/2 of RZ pulses through a delay circuit D, and applied to a transistor TR3 as an input 2 to generate currents I2. Since driving currents ILD to a semiconductor laser LD take a current value IB smaller than a threshold value for a period of a low level immediately after a high level in input pulses ''1'', charges in the semiconductor laser LD disappear for the period.

Filed: 1985-03-16
Abstract: PURPOSE:To keep secrecy of data stored in a data memory by erasing a program for performing a data reading and writing by a data memory stored in a non-volatile memory when a predetermined numbers of erroneous pass- words are inputted. CONSTITUTION:When inputting a pass-word from a terminal, a processor 3 reads the pass-word from an area 6 of a program memory 4, collates with the inputted pass-word. When both the pass-words do not coincide, it is decided that the inputted pass-word is error, making a counting value of the erroneous pass-word '1', and simultaneously, from the area 6, preset regulating numbers are read and compared. In this manner, every time when the erroneous pass- word is inputted, a counting is done and when the counting value exceeds the regulating number, the processor 3 feeds an erasing signal (a) to a program memory 4 and an ordinary processing program stored in the area 6 is erased. Thereby, the processor is not operated, it is impossible to find the pass-word stored in an IC card, so that the secrecy of the data can be kept.

Abstract: PURPOSE:To maintain excellent sealing performance without slipping off and improve durability by filling and solidifying resin in a ring groove by injection molding for forming a piston ring combined with a piston ring in one body, and high-accurately finishing the ring through machining. CONSTITUTION:In a piston 20, a piston ring 26 is formed by a method wherein a material is filled and solidified in a ring groove 22 by injection molding by use of molds 40, 40 for injection molding with a cavity 41 for the piston ring. The piston ring 26 is provided in the ring groove 22 of the piston 20 directly by filing an solidifying resin through injection molding.

Further, as the ring 26 is strongly combined with the piston 20 in one body through the ring groove 22, there is no possibility of slipping off, and it has high durability.
