Title: Ignition distributor for internal combustion engine
Inventor: SONE MASAZUMI
IPC: F02P7/02
Filed: 1981-02-23
Abstract: PURPOSE:To effectively prevent generation of a radio noise, by constituting a rotor electrode with a metallic electrode of low heat conductivity and a ceramic resistor arranged to a center carbon side. CONSTITUTION:A rotor 21 is mounted with a rotor electrode 22 to the upper side of an insulating member 4, and the electrode 22 is formed by using a rivet 25 to secure a metallic electrode 23, consisting of metallic material, for instance, stainless of low heat conductivity in thickness of 0.1-1.0mm., to a ceramic resistor 24. In this constitution, large thermal resistance of the metallic electrode 23 causes temperature of the rotor electrode 22 to rise higher than that as in the past arising from the electric discharge with a side electrode 8. Accordingly, an electron is actively emitted to both lower discharge voltage by this thermion effect and decrease a capacity discharge current, and generation of a harmful high frequency component can be reduced.

Title: Document transport apparatus
Inventor: WATANABE KOUICHI
IPC: B65H9/00
Filed: 1984-02-14
Abstract: PURPOSE:To replace the contaminated guide surface by rotation and keep constant a gap between a guide member and a platen glass by regulating the position of the guide surface to the glass in such a manner that the guide surface of a rotatable polygonal guide member is opposite to the platen glass. CONSTITUTION:When the guide surface of a guide member 34 that is opposite to a platen glass is contaminated, an arm is turned clockwise and a supported portion 36 of the guide member 34 is positioned at a circular hole 32 to turn the guide member 34 in 45 deg. arc in either direction. After that, the supported portion 36 is advanced into a square hole 33, and the arm is turned counter-clockwise to be engaged with an engaging member, so that the uncontaminated guide surface of the guide member 34 is opposite to a platen glass 3. If all of the eight guide surfaces are contaminated, the guide member 34 can be replaced while the arm is not detached. The position of the guide surface opposite to the platen glass depends upon the thickness of a position regulating member 38. If the thickness is set about 1.0mm., the gap between both members is always kept about 1.0mm..

Filed: 1991-02-19
Abstract: PURPOSE:To improve forging prevention effect by varying the film thickness of a photosensitive material partially in proportion to reproduction wavelength so that, for example, a specific pattern is obtained. CONSTITUTION:When plate 1 whose surface is coated with the photosensitive material is irradiated with laser light having specific wavelength and exposed to photograph a Lippmann hologram image 2 on the dry plate 1, the thickness of the photosensitive material is varied partially in proportion to the reproduction wavelength so that, for example, the specific pattern 3 is obtained. Namely, the part where the film thickness is varied and other parts are reproduced in different colors by varying the film thickness of the photosensitive material partially in proportion to the reproduction wavelength. Thus, the reproduced image is not obtained (can not be copied) with laser light of one color and multiple exposure using plural lasers is required.

Title: Pressure adjusting valve
Inventor: TSUJIMURA KENJI
IPC: G05D16/16
Filed: 1985-02-13
Abstract: PURPOSE:To supply quickly the pressure fluid corresponding to the dropped pressure by shifting a piston, a supply valve and an adjusting valve in the opening or closing direction in accordance with the strength of the pressure of a channel side and that of a secondary side passage. CONSTITUTION:When the air pressure of the secondary side channel 44 drops rapidly from a set pressure, a membrane plate 19 rises from its set position, and a pressure adjusting valve 16 opens the channel 15a. Then an air flow C passes through the channel 15a to be come an air flow D, and the air of a primary side passage 45 flows rapidly into the secondary side passage 44 to raise the air pressure of the channel 44. However the piston 34 descends by a stop 35, receiving force downward. Then the supply valve 38 descends to open the channel 32, and an air flow E is generated and applied to the air flow D, whereby air is quickly replenished to the aisle 44 from the aisle 45. Next, when the air pressure of the aisle 44 approximates to the set pressure, the pressure downward caused by the stop 35 is decreased, and the channel 32 gradually closes, whereby the air flow E disappears. When the air pressure of the passage 44 comes to the set one, the pressure adjusting valve 16 closes the channel 15a, and the air flows C and D disappear.

IPC: G11B5/85
Filed: 1985-02-12
Abstract: PURPOSE:To obtain a gamma-Fe2O3 layer magnetic recording medium having small crystal grains and excellent noise characteristic of small SNR at a high film forming speed with good productivity by forming an Fe3O4 layer on a heated substrate by a magnetron sputtering method in which a magnetic field is generated on the surface of a target to capture electrons. CONSTITUTION:The substrate 2 in a magnetron sputtering device is kept heated to 200-250 deg.C by a heater 13 for heating the substrate before the start the sputtering. Sputtering is then executed at a film forming speed of 100Angstrom /min by the magnetron sputtering method to form the Fe3O4 layer on the substrate 2 and the Fe3O4 layer is oxidized to form the gamma-Fe2O3 layer. The magnetic fiels is generated on the target surface by a permanent magnet 12 and the electrons are captured by such magnetic field so that high-density plasma is generated near the target in this magnetron sputtering method. As a result, the collision of the electrons against the substrate 2 is decreased and the temp. rise of the substrate 2 is suppressed even if the film forming speed increases. The substrate temp. is therefore required to be made 200-250 deg.C in order to obtain the Fe3O4 layer having good quality.
