Title: Auxiliary lock for aluminum double sliding door or window
Inventor: NIISATO MASAHIRO
IPC: E05C17/60
Filed: 1999-05-14
Abstract: PROBLEM TO BE SOLVED: To serve as an auxiliary lock by attaching a guide rail to a double sliding door or a sliding screen and inserting a stopper from an insertion opening for the stopper to regulate the opening of the insertion sliding screen. SOLUTION: A guide rail 2 having a specified length and thickness is fixed in a screw hole 3 by a screw from the indoor side in an outside sliding screen in a state that an aluminum double sliding door is closed. A stopper 1 is inserted from an insertion opening 4 for the stopper. The opening is restricted to have a slight length to prevent invasion from outside. The stopper 1 is not released if the sliding screen is not completely closed and if a hand is put in from the outside, the stopper is not released. Since the screw hole 3 of the guide rail 2 is concealed by the inside sliding screen when the sliding screen is opened even a little, even if a hand is inserted from the inside, the stopper can not be removed.  Further, when the rail 2 is shaped to have a specified thickness, it can be installed in almost all doors or windows and crime prevension can be realized while ventilating indoor space. In this way, even if one forgets to lock an existing lock, it serves as an auxiliary lock to prevent invasion from the outside.

Title: Method for adding impurity
Inventor: HAYASHI HIROSHI
IPC: H01S5/00
Filed: 1980-12-04
Abstract: PURPOSE:To control the quantity of fine impurities to be added into a growing layer accurately, by employing a semiconductor crystal, which has the same composition as that of a source crsytal which is to become a growing material and on the surface of which a thin film comprising an impurity element to be doped is deposited, as an impurity material used for liquid phase epitaxial growing. CONSTITUTION:It is very difficult to measure very small amount of metal Te when a Te doping type Ga0.5Al0.5As layer, which has impurity concentration such as carrier concentration of 5X20<17>/cm<3> at a growing temperature of 800 deg.C, is grown on a substrate such as GaAs. Therefore the following method is employed. The growing material is constituted by Ga, Al, GaAs, and Te. However, since the quantity of inclusiion of Te is as extremely small as 0.035mg, a GaAlAs crystal, on which a thin Te film is deposited to about 1mum, is employed instead of using metal Te. At this time the impurities to be added are not limited to Te. In this method, extremely fine quantity of impurities can be added.

Title: Signal processing circuit for television receiver
Inventor: NAKAGAKI NOBUFUMI
IPC: H04N5/208
Filed: 1986-07-23
Abstract: PURPOSE:To suppress line flicker disturbance and to improve the sharpness of a picture by providing a vertical contour emphasis function to a noninterlace conversion circuit. CONSTITUTION:A Y/C separation circuit 203 separates a luminance signal and a color difference signal form a composite video signal 201. An interpolation signal suppressing line flicker disturbance is obtained by a scanning line interpolation circuit 101 and the original signal subjected to optional emphasis of vertical contour and the interpolation signal are obtained by a vertical contour emphasis circuit 104, and thereby, the separated luminance signal is converted into a signal whose horizontal frequency is doubled by a double speed conversion circuit 102. Further, the color difference signal is separated into two systems of color difference signals (I, Q or R-Y, B-Y) by a color demodulation circuit 204 and converted into a signal whose horizontal frequency is twice by a noninterlace conversion circuit 103. A signal from noninterlace conversion circuits 102, 103 for luminance and color difference signals is converted into an RGB signal by an RGB matrix circuit 205 and fed to a cathode ray tube 206. Thus, a picture whose vertical contour of the luminance signal is emphasized and whose scanning line number is converted into twice is obtained from the cathode ray tube 206.

Title: Optical information recording method
Inventor: KENJIYOU HIDESHI
IPC: G11B20/18
Filed: 1980-12-05
Abstract: PURPOSE:To confirm the recording of information on real-time basis by reading information immediately after its recording and by comparing it with the quantity of reflected light from a part where no information is recorded. CONSTITUTION:When a pit is formed correctly, the quantity of reflected light from the point in time when the output intensity of a semiconductor laser 21 decreases to a readout level until the point in time when the pit passes by the irradiation position of a light beam spot completely becomes less than that where no pit is formed. An output generated when no information is recorded is sampled and accumulated in a capacitor 38 through an analog gate 37 to obtain a threshold level signal having a level with a invariably constant difference from a level corresponding to the readout level of the semiconductor laser 21. This threshold level signal is compared by a comparator 34 and the difference is made into pulses to extract pit information, so that the pit information is made into pulses accurately all the time.

Title: Coating device for building plate
Inventor: YAMAGUCHI TAKAHIRO
IPC: B05B15/04
Filed: 1997-06-27
Abstract: PROBLEM TO BE SOLVED: To prevent the coating spraying orifice of a spraying means by preventing a coating from residing in the spraying means or a coating supply passageway for a long time during the stoppage of spraying. SOLUTION: A coating spraying orifice 30 for spraying a coating and a coating return orifice 34 for causing the coating to flow out are provided in a spray gun 17, and the coating spraying orifice 30 and the coating return orifice 34 are selectively opened/closed by moving a valve unit 61 vertically in the spray gun 17. During the stoppage of coating spraying, the coating spraying orifice 30 is closed and the coating return orifice 34 is opened by causing the valve unit 61 to descend. Consequently, the coating to be supplied from a coating head is caused to flow out of the coating return orifice 34 through the interior of the spray gun 17 and is returned to a coating tank side to be circulated. Thus the coating does not reside either in the spray gun 17 or in the coating supply passageway for a long time.  In addition, it is possible to prevent the coating from residing after the end of coating process, even by draining the residual coating from the interior of the coating head through a coating drainage aperture provided at the lower end part of the obliquely installed coating head.
