Title: Surface treatment
Inventor: MIYAKE KIYOSHI
IPC: H01L21/302
Filed: 1987-03-13
Abstract: PURPOSE:To make it possible to reduce a surface film consisting of such an oxide and a nitride as silicon dioxide by a method wherein the laser producing plasma of such gas as to contain at least one or both of hydrogen and a halogen element is produced and the plasma is irradiated on the surface of a semiconductor metal substrate. CONSTITUTION:A 248-nm wavelength laser beam 22, which is generated trom a Kr F pulsed excimer laser 21 is introduced into a vacuum container 25 through a 50-cm focal length convex lens 23 consisting of fused quartz and a window 24. The air in the container 25 is evacuated by a vacuum exhaust pump 26 and the degree of vacuum in the container 25 is held at 1X10<-2> Torr by making hydrogen gas 27 flow through a gas leakage valve. The repetitive frequency of laser pulse is set as 10 Hz and an Si substrate 28 is exposed to hydrogen plasma for about 10 seconds. By this plasma irradiation, a natural oxide film on the surface of the substrate 28 is removed. In such a way, by irradiating the plasma having a reducing action chemically to reduce the coated layer on the treated substrate surface, the natural oxide film is reduced and can be removed in a short time and also, holding the temperature of the substrate at low temperature.

Title: Reduction system for picture-quality disturbance of television signal
Inventor: SHIKINA TOMOE
IPC: H04N9/64
Filed: 1987-03-13
Abstract: PURPOSE:To reduce picture-quality disturbance by detecting a stationary and a dynamic area at a front stage where a luminance signal and a color signal are multiplexed, multiplexing a luminance signal Y and a color signal C through prefilters for Y and C in the dynamic area of multiplexing a luminance signal and a color signal which are not passed through both prefilters in the stationary area, and thus outputting composite signals respectively. CONSTITUTION:A comparator 15 compares the absolute value of a frame difference signal with a fixed value nearby zero to output a high-level signal when the absolute value of the frame difference signal is larger than the fixed value or a low-level signal to S terminals of switches 18 and 19 when the absolute value is smaller. Then when the high-level signal is outputted, namely, in a moving area, the luminance signal Y is passed through the prefilter 16 for Y and the color signal C is passed through the filter 7 for C; and they are multiplexed. When the low-level signal is outputted, namely, in the stationary area, both signals are not passed through the prefilters 16 and 17 for Y and C and interframe separation is employed as the Y/C separation of a rear-stage image receiver to prevent the resolution in the stationary area from the deteriorating. Then the Y and C signals are added by an adder 20 and inputted as a composite signal to a D/A converter 21.

Abstract: PURPOSE:To enable a striking lever to be guided with a rotating body, by providing the rotating body which is in contact with the other to either one of a bracket and the striking lever. CONSTITUTION:In desiring to change over a gear position of an arbitrary shift of a car, a control lever 49 is driven to a shift direction D while being rotated in a direction of selection C. Then the tip of the striking lever 47 slides a 5th speed-reversing fork rod 32 to a neutral position while being pressed with a roller 39.

Abstract: PURPOSE:To enhance oxidation resistance of the surface of a member made of nonferrous metals by performing nonaqueous chromate treatment on the surface of the member made of nonferrous metals to incorporate chromium and thereafter heating this member to fix the incorporated chromium into a shape difficult to be eluted. CONSTITUTION:A member made of nonferrous metals consisting of Al, Mg, Zn, Sn and alloy thereof is treated by the mixed liquid of a fluorine-based solvent such as trichlorotrifluoroethane and alcohol to perform preliminary washing. Then CrO3 and organic acid such as formic acid and acetic acid are dissolved into the above-mentioned mixed soln. Thereafter the member is immersed in this mixed soln. to stick chromium on the surface thereof and nonaqueous chromate treatment is performed. Successively setting treatment for stabilizing stuck chromium is performed by blowing hot air at 40-50 deg.C. Thereafter the member is immersed in high-temp. water mixed with the above- mentioned fluorine-based solvent and alcohol and pulled up to perform finish washing. Chromium stuck by chromate treatment is fixed by heat and prevented from being eluted. Thereby oxidation resistance of the member made of nonferrous metals is remarkably enhanced.

Abstract: PURPOSE:To surely and smoothly lock a shutter for a long period by forming a locking member for the opening/closing shutter of an aperture part so as to be canceled with its elastic deformation, and fitting the member so as to move in the sliding direction of the shutter. CONSTITUTION:The locking mechanism of biparting shutters 6 and 7 to close aperture pats 4 and 5 of a cartridge main body 1 consists of one lever shaped locking member 31, and the member 31 can move with respect to the main body 1. When the main body 1 is fitted in a recording/reproducing device, since operating pin pressured parts 33a and 33b are pressured, the locking member 31 is elastically displaced in an elastic displacing part 34, the lock of the shutters 6 and 7 is canceled, and slided in a releasing direction. In such a condition, by the elastic restoration of the elastic displacing part 34, the aperture parts 4 and 5 are completely opened. By the ejecting operation of the recording/ reproducing device, the shutters 6 and 7 are slided, the displacing part 34 is gradually flexed, and the aperture parts 4 and 5 are closed. Consequently, the displacing part 34 is not damaged even when the wall of the part 34 is made thinner, and the restoring force of the shutter 6 and 7 can be decreased.
