Title: Power-on type thermally transferable sheet
Inventor: SATAKE NAOTO
IPC: B41M5/26
Filed: 1989-12-08
Abstract: PURPOSE:To form a satisfactory printed image with an adequate density without base film rupture and crease generation by using heat-resistant film as a base film. CONSTITUTION:A sheet consists of heat-resistant base film 1, a thermally migrating dye layer 2 laminated on one surface of the film 1 and a resistance layer 3 laminated on the other surface. Polyethylene naphthalate film is recommendable as a heat-resistant base film in terms of filming process, workability and price. The resistance layer 3 which generates heat due to power supply should preferably be heat-resistant itself. That is, a resin layer which forms the resistance layer is cross-linked by ionizing radiation or heat and becomes heat- resistant. Consequently, the mechanical rupture of a transfer sheet is prevented and a printed image of high quality is obtained.

Title: Method for identifying method for displaying dimension value of drawing
Inventor: IWAMOTO RYUICHIRO
IPC: G06F17/50
Filed: 1999-11-09
Abstract: PROBLEM TO BE SOLVED: To eliminate the problem that much time has to be taken to check dimension values because all dimension values including automatically displayed dimension values must be checked to find the dimension values of erroneous manual input, although the number of places of the dimension values which are manually inputted and changed is small, because the displayed dimension values of manual input that might be erroneous are displayed on the screen in the same manner as the automatically displayed dimension values even though there is a case where only an input value is changed by manual input without changing a graphic in partial design change in the dimension values of a drawing prepared by using a CAD device. SOLUTION: In this method for dimension value display, only the dimension values of manual input are shown by differentiating the dimension values from the dimension values of an automatic display.

Title: Laser oscillation apparatus
Inventor: FUJIWARA JUNJI
IPC: H01S3/101
Filed: 1988-12-16
Abstract: PURPOSE:To oscillate, over a wide range, a laser beam radiated from a laser medium by a method wherein a cylindrical lens is installed between a beam expander and a grating. CONSTITUTION:An etalon 11 is arranged and installed between a grating 4 and a beam expander 6; the etalon together with the grating narrows a wavelength width of a laser beam. A cylindrical lens 13 is installed in front of the etalon 11 between the beam expander 6 and the grating 4. This cylindrical lens 13 is installed so as to reduce a beam width by using the beam expander. Since the cylindrical lens 13 is installed in this manner, a laser beam L is reduced after it has passed the cylindrical lens 13; the reduced laser beam is incident on the grating. As a result, the laser beam is returned mostly to the side of an output mirror; a loss of the laser beam is reduced and oscillation efficiency of the laser beam can be enhanced.

Simultaneously, the input/output of an inverter 105 is short- circuited, and the voltage of 1/2 of a power supply voltage is generated at the point B of the capacitor 106 and a capacitor 107. Thence, when the control clock 1 is set at H and the control clock 2 at H, all three switches are turned off, and the difference of electric charges between the capacitors 106 and 107 can be held. Thence, when the clock 1 is set at H and the clock 2 at L, the SWs 102, 104 are turned off, and the SW103 is turned on, then, the voltage at the point A of the capacitor 106 goes to the voltage of the analog signal. At this time, the difference of electric charges between the capacitors 106 and 107 holds the electric charge in autobalance, therefore, voltage comparison is performed.
