Title: Laser oscillator
Inventor: NAWA AKIYOSHI
IPC: H01S3/00
Filed: 1986-03-06
Abstract: PURPOSE:To prevent the decrease in reflectivity of a chopper, by rotating the chipper for detecting a laser light output in inactive gas. CONSTITUTION:A chopper 5 for detecting a laser light output is driven and rotated by a motor 6 and chips laser light 7. A part of the laser output is reflected and taken out by a sensor 8 as an electric signal. An inactive gas chamber 11 is fixed to an oscillator main body 1. Inactive gas such as N2 or dry air is inputted through a gas path 12 and exhausted through a gas exhaust port 13. The gas exhaust port 13 is provided on the same axis as the light path of the laser light 7 and commonly used as the passing hole of the laser light. Therefore, dust in atmosphere is not sucked into the chamber. The inside of the chamber 11 is filled with the inactive gas, and the intrusion of dust in atmosphere is prevented. Thus the deterioration of the chopper 5 can be prevented.

Title: Light source and projection display device
Inventor: HAMADA TETSUYA
IPC: G02F1/1335
Filed: 1996-03-05
Abstract: PROBLEM TO BE SOLVED: To obtain a light source with its superior durability and a projection display device using this source by arranging first and second electrodes non- symmetrically regarding the center of an outer shell part so that the maximum light emission part due to discharge is positioned at almost the center of the outer shell part. SOLUTION: First and second electrodes 14 and 16 are arranged more downward than a line 16 passing through a center O of an outer shell part 12, and thereby a maximum light emission part L due to discharge is positioned at almost the center of an outer shell part 12. Whereby, the outer shell part 12 is not degraded by locally subjecting it to strong light, and the service life of a light source can be expanded. When this light source is used for a projection display device, non-uniform brightness due to a position is not produced and a good display can be displayed.

Title: Data processor
Inventor: TASHIRO TOKUJI
IPC: G06F3/0481
Filed: 1992-03-05
Abstract: PURPOSE:To enable an operator to efficiently input data at the time of inputting data to a data base file on the data input picture displayed by an input format program by indicating the input position by display of a cursor on the display picture of a display device and allowing the operator to input a key to generate the data base file. CONSTITUTION:If a designation back key 1a on a keyboard 1 is depressed at the time of data input to the data base file, designation back position information in an input format program 10 is taken out, and the cursor display position on a display device 6 is returned based on this information. A prescribed mark is preliminarily set to the start position of a desired field by the program 10 to obtain the designation back position information. Thus, the cursor is returned to the start position of the preliminarily designated desired field by one key operation.

Title: Temperature sensor
Inventor: MORITO YUUKOU
IPC: G01K11/18
Filed: 1980-04-12
Abstract: PURPOSE:To obtain a temp. sensor which is small in its temp. detecting part, is easy to use and is inexpensive to manufacture by providing a material of which the light transmittance changes with temperatures on the way of the optical guide of the temp. sensor. CONSTITUTION:A temp. sensing part 3 made of plastics consists of a material of which the light transmittance changes with temperatures, for example, wax 4, into a cavity part 3a and optical guides 1, 2 made by bundling a suitable number of optical fibers, of which the end parts are mounted on both side of said part. When a light source 5 is put on, the light enters the optical guide 1 and advances therein, but since it is cut off by the wax 4 of low light transmittance at low temp., a photoelectric converter 6 does not transmit any detection electric signal. Whereas, when the temp. of the temp. sensing part rises, the wax 4 becomes gradually transparent and increases its light transmittance, resulting in increased quantity of light entering the optical guide 2 and increased detection electric signal by the converter 6. Thus the temp. rise of the part to be detected is detected.

Title: Oscillator
Inventor: KINUGASA TOSHIRO
IPC: H04N3/14
Filed: 1987-03-04
Abstract: PURPOSE:To facilitate the change in a frequency of a horizontal scanning pulse by providing a means controlling the pulse width of horizontal period so as to control the frequency of the horizontal scanning pulse. CONSTITUTION:A rising or falling of a horizontal period pulse phiH generated by an oscillator 1 is retarded (2) to generate a horizontal period pulse phiH' whose pulse width is changed. A VCO 3 starts oscillation after a prescribed period from the falling of the pulse phiH' and outputs a clock phiCLK used to generate a horizontal scanning pulse. A pulse 6 having the n-th pulse phase information of the phiCLK is generated by a frequency divider 4 to apply the pulse 6 and the rising phase of the phiH' at a detector 5. Then the VCO 3 is controlled by using a control voltage 7 so that both the phase are made coincident.

Abstract: PURPOSE:To shorten the processing time considerably, by previding a register for holding information of an operation exeucting instruction, waiting registers for holding instruction before execution, and a means which compares the executing instruction with the instruction before exection to execute the instructions in order. CONSTITUTION:Instruction information is set to a fetch register 10. On condition that register interference check circuits 13-1 and 13-2 indicate non-register interference, a waiting register making control circuit 11 transfers instruction information of the fetch register 10 to a waiting register 12-1 or 12-2. A selector 14 selects the waiting register 12-1 or 12-2 by the control of a selecting control circuit 19. On condition that refister interference check circuits 18-1 and 18-2 indicate non-redister interference, an instruction transmission control circuit 15 transfers the output of the selector 14 to an adding register 17 or a multiplying register 16 and transmits start information for an operation processing part simultaneously.

Title: Ejector pin for plastic
Inventor: UNNO KOUZABUROU
IPC: B29C45/40
Filed: 1984-03-13
Abstract: PURPOSE:To provide the titled ejector pin having good toughness and wear resistance by subjecting a bar material which consists of a steel having the specific compsn. consisting of C, Si, Mn, Ni, Mo, Al, Ti, Co and iron and is subjected to a soln. heat treatment to a nitriding treatment at an adequate temp. after forming. CONSTITUTION:A softened bar material which is made of the steel consisting of <=0.03wt% C, <=0.20% Si, <=0.20% Mn, 15.0-20.0% Ni, 2.9-5.0% Mo, 0.02- 0.25% Al, 1.25-2.0% Ti, 2.1-4.0% Co and the balance iron and impurities and is subjected to a soln. heat treatment is worked to a prescribed shape by machining, etc. The formed article is thereafter subjected to a nitriding treatment at about 470 deg.C to harden the surface and at the same time to induce age hardening in the inride. The plastic ejector pin having excellent resistance to wear and seizure and good toughness is thus obtd. The expansion by the nitriding treatment is negated by shrinkage owing to the age hardening by which the dimensional change is substantially eliminated. The dimensional accuracy in the diameter of the small-diameter pin for a precision plastic die is thus easily improved.

Thus, the work 5 is strongly adhered to the fixing surface 30 by the coagulation molecules of the frozen high polymer coagulant. Since the fixing state of the work 5 is thereby obtained, a machining device is actuated and desired machining is performed by a tool 2. At this time, machining solution or cooling gas is supplied to a contact part area between the tool 2 and the work 5. After the machining, when the supplying of the machining solution or the cooling gas is stopped, the temperature of the fixing surface 30 is returned and the machined work 5 is removed.
