Title: Optical apparatus for collimation of light
Inventor: FUREDERITSUKU AASAA RANDORU
IPC: H01L31/0232
Filed: 1989-11-22
Abstract: PURPOSE: To obtain the matching of optical axes through the matching of the outside diameters only by using a multimode.fiber which acts as a graded.index.lens. CONSTITUTION: A first optical transmission.reception.waveguide device has an optical fiber 2. A second optical transmission.reception.waveguide device has a photodetector 8 which is mounted on the axis that is same as the axis of the fiber 2. A different optical fiber portion 10 is arranged between the fiber 2 and the photodetector 8. The portion 10 is a multimode.fiber having a core region 12, which is made of graded.index materials, converges the light beams from the fiber 2 and focuses the beams on the photodetector 8. Thus, two optical fibers are correctly coupled similar to the case in which a coupling is easily made by using a tubing device or a V shaped groove device.

Title: Address decoder for semiconductor memory
Inventor: KAMURO SETSUSHI
IPC: G11C11/408
Filed: 1989-11-24
Abstract: PURPOSE:To prevent a large current from flowing by activating a word line smoothly when a reset signal is inputted and activating or inactivating the word line corresponding to the contents of a select signal when the reset signal is not inputted. CONSTITUTION:When a reset signal RST is not inputted, a first transistor TR 115 is turned ON on the side of a word line W1. Accordingly, between a power source and the line W1, a current to flow through the TR 115 and a second TR 114 is generated parallelly with a route flowing through a fourth TR 116. At such a time, the current flows from the power source through the TR 114 with high electrifying ability to the line W1 at high speed and the line W1 is activated. On the other hand, when the signal RST is inputted, a third TR 113 is turned OFF and the TR 116 is turned ON. At such a time, the current path through the TR 115 and 114 is interrupted. Accordingly, the current flows from the power source only through the TR 116 with small electrifying ability to the line W1 and the line W1 is smoothly activated. Thus, the data of each memory cell are reset, the large current can be prevented form simultaneously flowing.

Abstract: PURPOSE:To shorten dewaxing time in dewaxing an injection molded or extrusion molded article comprising metallic or ceramic powder and an organic polymer binder with an organic solvent and sintering, by using a combination of a component soluble in an organic solvent and a component insoluble in the organic solvent as the binder. CONSTITUTION:Metallic or ceramic powder is blended with a binder consisting essentially of an organic polymer, kneaded and pelletized to give a mixture, which is injection molded or extrusion molded to give a molded article of desired shape. In the operation, the organic polymer contained as the binder is a combination of one or more of a solution soluble in a certain organic solvent and a component insoluble in the organic solvent. Only the soluble binder component is extracted by a method such as immersing the molded article in a certain organic solvent and the molded article is sintered to give a sintered product. By this method, the molded article can be dewaxed in a shorter time than by heating dewaxing method and the shape of the molded article will not be damaged because the polymer insoluble in an organic solvent is left.

Abstract: PURPOSE:To certainly detect dripping even under any dripping detection environmental condition by setting the averaged voltage of the peak voltages of light detecting electric signals received at the time of no liquid droplet. CONSTITUTION:The light detecting pulse photoelectric voltage received by a light detection sensor 5 is inputted to a peak voltage averaging circuit 9 to be outputted as the averaged voltage of light detecting pulse photoelectric voltage peaks and said averaged voltage is inputted to the positive polarity input terminal line 8 of a voltage detector 6.

Title: Manufacture of semiconductor laser
Inventor: KAWANAMI HIROSHI
IPC: H01S5/00
Filed: 1991-11-21
Abstract: PURPOSE:To easily remove polycrystal growing on the upper portion of a resonator by using hydrochloric acid at room temperature, a solution mixed with hydrogen peroxide or an aqueous solution of sodium hydroxide of a particular temperature in a process of masking SiO2 over a resonator and removing a semiconductor portion of II-VI group compounds formed on the resonator. CONSTITUTION:The portion lowered by etching is buried to the same height as that of a p-type Al0.1 Ga0.9As contact layer 108 by forming a ZnSe layer 109 around the light emitting portion of a columner shape. During this burying a polycrystal ZnSe grows because SiO2 112 has been formed on the potion 108. This polycrystal ZnSe is immersed in an etching solution comprising HCl: H2O2:H2O at room temperature, and only the polycrystal is selectively etched. For the etching of polycrystal ZnSe, a mixed solution of hydrochloric acid and hydrogen peroxide is used, but the same effect can be obtained even though an aqueous solution of sodium hydroxide of 100 to 120 deg.C can be obtained. By doing this, the production process can be simplified and yield can be obtained.

IPC: H04N5/208
Filed: 1992-10-19
Abstract: PURPOSE:To obtain a contour correction circuit which performs the optimum contour correction corresponding to the band area of the luminance signal of an inputted video. CONSTITUTION:A contour signal formation circuit 2 obtains a contour signal Al from an inputted luminance signal Yin, and supplies it to a gain control circuit 3. Meanwhile, an HPF 6 extracts a high-pass component C1 from the luminance signal Yin, and detects the peak value C2 of the high-pass component C1 by a smoothing circuit 7. An arithmetic circuit 8 calculates the control voltage Vc of a gain control circuit 3 from the peak value C2 and a control signal S. The circuit 3 amplifies the contour signal A1 by the control voltage Vc, and outputs a contour signal A3, and emphasizes the contour part of the video by adding the contour signal A3 on an original luminance signal by an adder circuit 4. At this time, the arithmetic circuit 8 supplies the control voltage Vc to decrease the gain of the gain control circuit 3 when the peak value C2 is larger and to increase the gain as the peak value C2 goes smaller, and sets the control voltage Vc at '0' when the peak value C2 goes smaller than a certain constant value.

When a concave mirror is used as the mirror 2, a matter projected to the mirror 2 can be enlarged so as to be easily observable. Thus, the mirror 2 is used in the bottom surface of the toilet bowl, whereby, the hardly visible part can be ordinarily observed by oneself so as to be useful for health management for hemorrhoid or the like.

Title: Drive controller for electrostatic type display device
Inventor: HATA KAZUO
IPC: G09G3/34
Filed: 1987-12-07
Abstract: PURPOSE: To prevent the generation of an error in displayed contents by turning on/off a power source for applying voltage and shifting the on/off of a power source for operation control by a prescribed time. CONSTITUTION: When a signal 6X is turned on, the power source of a control part V (+5V)6 starts outputting +5V to establish normal output (+5V) after time T1 and a microprocessor μP starts operation to start a shift register control circuit. Though the power source switch 12 of a display unit is turned on after the lapse of time T2 after the signal X6 is turned on, a control signal supplied for each display element through a resistor Rg at this time does not generate abnormal data along with the unstableness of the power source voltage of a power source 6 and abnormal data along with the unstableness of the operation of a logical circuit because regular display data being each output to shift registers S1 to SM is inputted to controlling signal switches SW11 , SW1n ,... SWMn . Next, the power source switch 12 and the output control signal 6X of the power source 6 are simultaneously turned off. Thereby the generation of abnormal output is avoided.
