Title: Production of blazed grating
Inventor: ONO YUUZOU
IPC: H04W12/00
Filed: 1979-05-29
Abstract: PURPOSE: To make the manufacture of the brazed grating of arbitrary blaze angles by letting a photoreceptor which has been removed of unexposed portions by development make close contact with an original opaque relief grating plate and exposing the same from an oblique direction and developing the same after peeling.  
     CONSTITUTION: The photoreceptor 2 coated on a transparent substrate 1 is compression-bonded by a hot press to an original grating plate 3 having a relief grating. It is exposed from the direction 4 of which angle 5 corresponds nearly to a blaze angle, thence the photoreceptor 2 is peeled from the original grating 3. When the unexposed portions shown by oblique lines are removed by development, the blazed grating is obtained. The original grating plate is made opaque by contact-exposing the grating recorded in black and white on a dry plate onto a photoresist film or manufacturing a holography and forming a silver film through electroless plating or silver mirror reaction. Hence, the blazed grating of arbitrary blaze angles may be readily obtained.

Title: Simple manometer
Inventor: TAKANO FUMIO
IPC: G01L7/18
Filed: 1997-03-19
Abstract: PROBLEM TO BE SOLVED: To obtain a simple manometer in which the tolerance of a pressure difference can be set easily by a method wherein a flexible and transparent tube is held in a state that it is bent to be U-shaped, a liquid in a proper amount is poured into the tube and a thrusted object as a mark expressing the tolerance of the pressure difference is installed in the tube in such a way that its position can be adjusted. SOLUTION: When a simplified manometer is applied to, e.g. a dust collector, the end P1 , on one side, of a tube 11 is connected to a dust side (a primary side) while a filter is used as a boundary, and the end P2 , on the other side, of the tube 11 is connected to a clean side (a secondary side). While the dust collector is operated, a pressure difference according to a state that the filter is clogged is generated between the dust side and the clean side. Due to the pressure difference, a level on the side of the end P1 on one side is lowered, and a level difference is generated between the end P1 on one side and the end P2 on the other side. As long as the level difference is smaller than the head between both ends of a string 13, the state that the filter is clogged is judged to be a normal range. When the level difference becomes large and when the level on the side of the end P1 on one side or the end P2 on the other side comes into contact with the end of the string 13, the operation is judged to be abnormal in such a way that the filter must be replaced.

Title: Circuit breaker tester
Inventor: KURISUTOFUAA JIERARUDO UOOKAA
IPC: H03K17/00
Filed: 1989-03-18
Abstract: PURPOSE: To eliminate a separate power source by constituting this test device of a first switch, a light emitting diode, a current limiting resistor, a first resistor, a potentiometer, a second switch and a second resistor and internally feeding the test device by the power source of a trip unit. CONSTITUTION: This test device 10 is fed from the internal power source of an electronic trip unit 12 under test. As a result, it becomes unnecessary to connect a separate power source to the test device 10. When the first switch 40 of the test device 10 is closed, an LED 42 emits light to make a current flow through a current limiting resistor 44. Also, a voltage is applied between the movable arm of a potentiometer 48 and a grounding terminal Gnd. When a second switch 50 is closed, a voltage is applied as an input test signal through a terminal Vin to the electronic trip unit 12 to which a conductor for an input test signal is connected. The set point of the potentiometer 48 is adjusted to be able to increase and decrease the magnitude of the input signal of the terminal Vin.

Title: Printed wiring board and supporting board for thermal head
Inventor: OOYANE KOUJI
IPC: B41J2/345
Filed: 1999-03-12
Abstract: PROBLEM TO BE SOLVED: To provide a printed wiring board for thermal head in which the surface and rear can be discriminated easily. SOLUTION: In a thermal head comprising an insulating board formed with heating elements and a printed wiring board abutting fixedly against a supporting board, a cut 51a for discriminating between the surface and the rear is made from a central part in the longitudinal direction of the printed wiring board to a part of the outer circumference of the printed wiring board on one side thereof thus shaping the printed wiring board asymmetrically with respect to the longitudinal direction. Since directional confirmation of each sheet can be eliminated by loading the printed wiring board, while matching the shape, to a magazine being used for automatic carrying line during manufacture of the thermal head, the printed wiring board can be prevented from being secured upside down to the supporting plate.

Title: Inspecting method of arranging accuracy of exposure shot
IPC: H01L21/30
Filed: 1992-03-26
Abstract: PURPOSE:To prevent production of dust due to exfoliation of arranging accuracy inspecting pattern by opening a light shielding blade only when an outermost part is subjected to shot exposure and forming a pattern for inspecting the arranging accuracy of shot in a region where a product pattern is not formed. CONSTITUTION:Arrangement accuracy inspection patterns A are formed at right and left positions rate from a product pattern 1 by opening the light shielding blade B1 of an aligner only when an outermost part is subjected to shot exposure. Only a shot pattern is released through the light shielding blade at the time of normal shot (shot for a part other than outermost part). Arrangement accuracy inspection is described for only lateral direction, but it is also true for vertical direction. Since the arrangement accuracy inspection pattern A for shot can be formed in the vicinity of wafer edge remote from the product pattern 1 or in a region at the outside of wafer on a mask, production of dust due to exfoliation of the arrangement accuracy inspection pattern A can be prevented.

Abstract: PURPOSE: To prevent shocking brake force operated at a valve mechanism when an engine rotates at high speed by so forming the hydraulic pressure in a brake chamber of a valve lift device as to control the pressure less than set value by a relief valve.  
     CONSTITUTION: Before a cam shaft 1 rotated by an engine pushes up a lifter body 5, oil flown from an oil inlet 11 is flown through a supply groove 12 and oil feed hole 13 of a plunger 6 into an oil feed chamber 14 and through a variable throttle hole formed by a slit 15 and a flange 9 into a brake chamber 10. The oil also pushes down a ball 18 to thereby flow into the hydraulic oil chamber 26 through throttle hole 27, escape groove 28 and drain oil hole 29 out. When the plunger 6 is then lowered upon closure of the valve 25 after opening the valve 25 upon rotation of the cam shaft 1, the opening area of the slit 15 becomes small to thereby increase the reaction against the droppage of the plunger 6 so as to thereby reduce the impact upon closing of the valve 25.

Title: Method for controlling quantity of electrostatic charge of toner in recorder
Inventor: IZUMI HIROKI
IPC: G03G15/08
Filed: 1982-04-23
Abstract: PURPOSE:To prevent the decrease in the quantity of uniform electrostatic charge and to eliminate ground contamination by bringing a conductive member into contact with the toner layer after uniform electrostatic charging, detecting the electric current leaking from the toner layer through said member, and controlling the voltage to be impressed so that the leak current attains a prescribed reference value. CONSTITUTION:A donor 1 is turned, and while a toner layer is formed with a doctor 3, the toner layer is electrostatically charged uniformly. The electric current leaking from said toner layer is detected through a roll 21. The leak current flows through a resistor R to a grounding part and the leak current value is detected as a potential value at the point M. The potential is amplified with an amplifier 10 and is inputted as a control signal for quantity of electrostatic charge to a voltage control circuit 11. The circuit 11 controls a variable power source E1' in accordance with the signal inputted thereto. Then, the voltage to be impressed on the doctor 3 as an implanting electrode is changed and the quantity of electrostatic charge in the toner layer is changed. If the leak current coincides with the reference value, the circuit 11 fixes and stores the magnitude of the power source E1' till the control of the next time.
