Title: Silicon etching gas silicon etching method
Inventor: KADOMURA SHINGO
IPC: H01L21/302
Filed: 1986-09-19
Abstract: PURPOSE:To prevent the chap formed on the surface of a groove, a hole, etc. by using a material which contains a gas having at least carbon and hydrogen atoms in the structure of a molecule. CONSTITUTION:A material which contains a gas having at least carbon and hydrogen atoms in the structure of a molecule is used. The gas which has at least carbon and hydrogen atoms in the structure of a molecule is also added or the above-mentioned gas is used under the conditions of etching at least during the process of dry etching. For example, C2H4 is added to make the flow rate about 6 % of the total quantity to the mixed material of SiCl4 and N2 in the flow rate of 1:1. By using the etching gas, an Si substrate 1 is etched by RIE by using SiO2 as a mask and a groove 2 which has great aspect ratio is formed. This can prevent the surface chap 4 of the side wall of the groove 2 and can prevent the swell on the side wall and the generation of the sub- trench of the bottom.

Title: Drop out compensating circuit
Inventor: IWASE MIKI
IPC: H04N9/88
Filed: 1987-09-07
Abstract: PURPOSE:To prevent a false color from being generated in a color picture, by executing the drop out compensation of a modulation color video signal by a first drop out compensating means for detecting and compensating the drop out of a luminance signal and a second drop out compensating means for detecting and compensating the drop out of a chroma signal. CONSTITUTION:At the time of compensating the drop out of an FM color video signal read from a magnetic recording medium, an FM color video signal is separated to an FM luminance signal (Y+S)FM and an FM chroma signal CFM. Thereafter, the drop out is respectively detected by the drop out compensating circuits 3, 15 disposed in the respective signal systems to compensate the drop out of the respective FM signals in an FM state. Thereby, even if there is the drop out in the FM luminance signal, when the FM chroma signal CFM is situated in a level which can be demodulated, the drop out of this FM chroma signal CFM is not compensated to prevent the generation of the false color.

Title: Measurement discriminating method for laser type gas sensor
Inventor: DOI SHOJI
IPC: G01N21/39
Filed: 1988-09-08
Abstract: PURPOSE:To discriminate whether measured data is effective or not and to improve the reliability by invalidating a standardized signal only at the time when a difference signal exceeds two threshold ranges and a laser current value is between two minimum points of the standardized signal. CONSTITUTION:When it is supposed that the standardized signal quantity for the laser current, which is changed stepwise, in each stage is one point, the difference spectrum at a difference of 10-point width in 1024 points is as shown in a figure (a) in the case of a figure (b). Minimum points ML and MR are points where the difference signal is changed from negative to positive, and a maximum point MAX in the point where the difference signal is changed from positive to negative. The first threshold is a positive threshold T+, and the second threshold is a negative threshold T-. Meanwhile, the difference signal at a mode hop occurrence point (e) greatly exceeds the threshold T- as shown by a point E. This point E is between points MAX and MR out of three extreme values where the extent of absorption is obtained. Consequently, it is judged by the existence of this point E that measurement at this time is ineffective.

Title: Transfer table for thermal transfer equipment
Inventor: IZUMIHARA HIROSHI
IPC: B41F1/38
Filed: 1982-12-20
Abstract: PURPOSE:To enable effective heating of a pressure plate by a method wherein the body of a table is made up of a pressed substrate comprising a non-conductive hard insulator and a conductive pressure plate is mounted on the outer surface thereof to perform a self-generation of heat with an electromagnetic induction by an induction coil within the body of the table. CONSTITUTION:In a heat transfer machine, as a high frequency current flows through an induction coil 14 in the body 12 of a table, an alternating magnetic field is generated and transmits with a non-conductive pressed substrate 12b without acting thereupon at all and acts upon a conductive pressure plate 13 alone to induce an induction current according to changes in the magnetic field within the pressure plate. In this manner, the pressure plate 13 generates heat due to an ohm loss thereof and concentrates it on the pressed surface 13a without waste being intercepted with a heat insulating pressed substrate 12b. This enables effective and quick heating of the pressure plate thereby eliminating preheating at the start of the transfer work while shortening the required time for temperature recovery at each transferring.
