Title: Formation of pattern
Inventor: ODA MASATOSHI
IPC: H01L21/3065
Filed: 1985-02-15
Abstract: PURPOSE:To provide a fine pattern on a part of the surface of a layer to be processed by a method wherein a groove, which is shallow and has an unflat bottom, is formed in the surface of the layer to be processed, masking having a large dry etching-resistant property is performed on the groove by a directional adhesion method, and after the fragile mask on the groove is removed, a dry etching is performed on the layer to be processed. CONSTITUTION:A PMMA22 is applied on the surface of a layer 21 to be processed, a drawing and a developing are performed with an electron beam and a groove 23, which is shallow and has the bottom formed in a U shape, is made. When an SiO2 film 24 is deposited using an ECR plasma deposition method, the film quality of an SiO2 film 25 on the groove 23 is turned into a fragile one. When the above-mentioned is dipped into solution containing dilute hydrofluoric acid of 3% of the composition thereof, the fragile film 25 is removed and a groove 231 is obtained. Successively, an etching is performed on the PMMA22 using an RIE method with O2 gas and a deep groove 232 is precisely formed. Moreover, when the first groove 23 is made larger its depth than its width, the SiO2 film 25 in the groove can be more selectively removed. According to this way, even a pattern so fine as 0.1mum or less can be precisely formed in a short time.

Abstract: PURPOSE: To devise to slant a shield fence automatically to the inside of a refrigerator as a door is opened and to return the shield fence above to the original position as the door is closed.  
     CONSTITUTION: When a door 42 is opened in about 90 degrees, a shield fence 50 equipped on an inner board 47 is turned round a shaft 51 from a position of a solid line to that of a broken line. At this stage, the second shaft 53 is moved inside a locus given round the shaft 51. The door 42 is turned round a hinge pin 45a, and a wire 55 connected with the second shaft 53 of the shield fence 50 in one end is given a fulcrum of a tying point 56 eccentrically provided to the hinge pin 45a. Consequently, a distance l, from this tying point 56 to a guide point 57 at the closing time of the door is changed into a distance l 2  on the basis of a locus 59 when the door 42 is opened by 90 degrees. This difference l 2 -l 1  is equivalent to the vertical shift l of the second shaft of the shield fence 50 above.

Filed: 1985-02-14
Abstract: PURPOSE:To distinguish a completely good produce from a defective product having a defect at an area whose error is correctable by including a means detecting the information bit inputted to an error correction circuit and presence in the error of check bit and outputting the result externally. CONSTITUTION:An output 16 of a parity check circuit 13 and information inputs D0-D7 are inputted to an error correction circuit 12, from which corrected information outputs A0-A7. Further, the output 16 of the parity check circuit 13 is inputted to a deciding circuit 14 comprising a NOR circuit to output an error detection output 15. If 1-bit error exists in the information inputs D0-D7 and the check inputs C8-C11, the syndrome of the output 16 goes to '0'. Even when the information outputs A0-A7 are not correct, if one-bit error exists in the inputs D0-D7, C8-C11, the output 15 goes to an L level. Thus, the completely good product and the defective product having a defect in error correctable area are distinguished from each other.

Abstract: PURPOSE:To prevent higher harmonic current from flowing between inverters operating in parallel. CONSTITUTION:A PLL circuit 31 is provided in order to synchronize PWM carrier of each inverter with a common bus voltage. A common bus voltage detection signal 32 is employed as a reference phase signal input and a PWM carrier signal, obtained through a phase comparing circuit 34, a VCO 36 and an UP/DOWN counter 37, is subjected to frequency division of 1/N through a frequency divider 38(N is the number of cycles of PWM carrier per single cycle of common bus voltage) to produce a feedback signal to the phase comparing circuit 34. Since PWM carrier of each inverter is synchronized with the common bus voltage, switching timing is matched for each inverter and thereby the output voltage waveform is matched resulting in elimination of higher harmonic current flowing between the inverters.

A pair of electrodes 3, 4 are embedded into the obtained powder, and said body is ignited to obtain a sintered body 1. This body is attached to a header 13 for the detecting element to obtain the gas detecting element for compensation. Since the sensitivity of said element is small only against CO, the sensor responding only to CO can be composed by the combination with the gas detecting element sensitive to CO.
