Title: Facing method for optical connector part
Inventor: SAITO TADAO
IPC: B24B19/22
Filed: 1986-07-10
Abstract: PURPOSE:To mitigate any drop in the transfer efficiency of light in connectedness of an optical fiber, by making an optical connector part at an end of the long-size optical fiber into a state of being clamped moving a grindstone in describing a conical surface as making it rotate, and machining an end face of the said optical connector part. CONSTITUTION:A grindstone 14 rotates with its rotation shaft 16 as the center, and a sleeve 15 is turned with its axis B as the center. Since a rotation axis A of the grindstone 14 is tilted to the center axis B of the sleeve 15, the grindstone 14 oscillatingly moves in describing a conical surface centering on the axis B of the sleeve 15 as rotating itself. An end face of an optical connector part 12 is forcibly applied to the grindstone 14 whereby the end face of the optical connector part 12 is machined in a conical form. At this time of this machining, the optical connector part 12 is clamped with a proper device and since the connector part 12 is ground, as aforesaid, by rotation of the grindstone 14 in one direction, no waviness occurs in an optical fiber 11 and a machining surface, therefore in connectedness of this optical fiber 11, a drop in the transfer efficiency of light is mitigated.

Title: Image forming method and recording medium
Inventor: MORIGUCHI HARUHIKO
IPC: G03F7/26
Filed: 1986-07-11
Abstract: PURPOSE:To easily obtain high-quality multicolor images and enable a recording medium to be used repeatedly, by evaporating an evaporable dye contained in a recording layer on a base. CONSTITUTION:A recording medium 1 comprises a recording layer 1a on a base 1b. Minute image forming elements 31 are distributed in the recording layer 1a, and each of the elements 31 contains an evaporable dye showing a respectively different hue. To form an image, the recording medium 1 is laid upon a thermal head 20, and is irradiated with light in the manner of covering the entire region of a heat generating part of the thermal head 20. In irradiation, rays of wavelengths for bringing the image forming elements 31 into reaction are sequentially used. When desired heat generating resistors are driven to generate heat simultaneously with the irradiation with light, the image forming elements 31 to which light and heat are applied are hardened, finally resulting in that a record image is formed in the recording layer 1 by the image forming elements 31 which are not hardened. In an evaporating step, the recording medium provided with the record image is brought into proximity to a medium to be recorded, and both of them are heated from the recording medium side or the side of the medium to be recorded, whereby the evaporable dyes are selectively evaporated, and an image is formed on the medium to be recorded.

Title: Catalyst carrier, its production and catalyst for decomposition of hydrazine
Inventor: AYABE TSUNEO
IPC: B01J23/46
Filed: 1992-06-22
Abstract: PURPOSE:To increase the catalytic active point and to obtain a catalyst having low temp. activity by increasing the specific surface area of catalyst carrier to a specified value. CONSTITUTION:An alumina carrier source material 2 is dipped in a soln. containing an Al compd. (e.g. aluminum. chrolide), while maintaining the liquid temp. to 50-100 deg.C and an alkali soln. is added to control the pH of the liquid to 7-10. After precipitating alumina hydrate 4 on the surface of the carrier source material 2, the carrier source material 2 is taken from the liquid and heated at 150-400 deg.C. This process is performed once or repeated several times to obtain an alumina carrier (A) having 330-500m<2>/g specific surface area. By depositing platinum elements such as Ir on the surface of this carrier, a catalyst having extremely high catalytic activity can be obtd. When this decomposition catalyst is used for a propelling device or the like, high decomposition efficiency can be obtd. even the hydrazine supplied is at low temp., and decrease in propelling force due to low temp. of the hydrazine supplied can be prevented. Thus, preheating of hydrazine to be supplied to the decomposition catalyst can be omitted.

Title: Electrostatic recording device
Inventor: UNEME KAZUHIKO
IPC: H05B3/00
Filed: 1988-06-29
Abstract: PURPOSE:To shorten a warming-up time by deciding a temperature at which a warming-up completion signal is outputted based on an output from a temperature sensor just after turning on a power source and controlling the application of an electric current to a heating element according to a previously set temperature. CONSTITUTION:The warming-up completion signal is allowed to be outputted when the surface temperature of a heat roll 1 attains the temperature Tt which is high enough to perform fixation. The higher the temperature Tn at the time of turning on the power source is, the higher the sensed temperature by a temperature sensor 3 at the time when the surface temperature of the heat roll 1 attains the fixation-enabled temperature Tt becomes and the more closely it approaches the surface temperature of said roll 1. The sensed temperature by the temperature sensor 3 at which the warming-up completion signal is outputted is changed according to the output from the temperature sensor 3 just after turning on the power source, that is, the sensed temperature by the sensor 3, and the signal is outputted at the sensed temperature as illustrated in figure. Thus, the fixation can be always performed completely and, besides to that, the warming-up completing time can be shortened.

Title: Exposure device for photosensitive sheet
Inventor: SHIROKURA AKIRA
IPC: H04N5/84
Filed: 1987-06-30
Abstract: PURPOSE:To effectively radiate a light beam from an exposure source on both surfaces of a photosensitive sheet and to shorten an exposing time by reflecting the light beam transmitted through the photosensitive sheet from the exposure source by a surface mirror and radiating it on the photosensitive sheet. CONSTITUTION:The photosensitive sheet 1 is arranged so that it abuts on the surface mirror 8 and an image which should be exposed is displayed with a cathode-ray tube 5. The image light l of the displayed image is radiated on a microcapsule layer 2 on a photosensitive sheet base 1a through a lens 6 and a color filter 7 so as to execute the exposure. The transmitted light is reflected on a reflecting part 8a and is made incident on the photosensitive sheet base 1a again. The image light is radiated on the microcapsule layer 2 from the opposite side to a direct irradiation from the cathode-ray tube 5 so as to execute the exposure. The microcapsule layer 2 is exposed with the image light which directly reaches from the cathode-ray tube 5 and it is radiated to be exposed with the image light which reaches by reflecting by the surface mirror 8 from both surfaces. If the luminance of the cathode-ray tube is same, the light quan tity which is nearly twice as much as in the case where there is no surface mirror can be radiated and the exposing time can be shortened.

These digital signals 8 are added by a signal synthesizer 3 to generate one digital signal 9 corresponding to the base band signal 7. A digital signal processing circuit 4 takes the digital signal 9 as the input and performs the digital signal processing to divide the signal by channel.
