Title: Gear with built-in one-way clutch and color image forming device using it
Inventor: OMURA KINYA
IPC: F16D41/06
Filed: 1998-08-31
Abstract: PROBLEM TO BE SOLVED: To provide a gear with a built-in one-way clutch by which the occurrences of a defective image due to defective meshing and abnormal wear and abnormal slip due to the intrusion of a foreign matter are prevented. SOLUTION: The gear with the built-in one-way clutch 141 is supported by a driving shaft 142 so as to be normally and reversely rotatable, and incorporates a one-way clutch 141B transmitting rotation in one direction to the driving shaft 142, and a bearing part 141b is formed at a part of a gear main body 141A forming a tooth surface 141a, and the gear main body 141A is freely rotatably supported by the driving shaft 142 through the bearing part 141b. Since the meshing of the gear 141 is highly accurately held at the clutch free time of the gear 141 (namely, when the gear 141 functions as an idler gear), the occurrence of the detective image such as pitch irregularity due to the defective meshing is prevented.  Also, the intrusion of the foreign matter of toner or the like from an interstice between the bearing part 141b of the gear main body 141A and the driving shaft 142 is prevented, so that abnormal wear and abnormal slip caused by the foreign matter are prevented.

Title: Patterning method for chromium film
Inventor: TSUTSUMI MICHINARI
IPC: H01L21/308
Filed: 1987-09-28
Abstract: PURPOSE:To form an etching edge face of a chromium film into a tapered shape by forming a pattern by using a polymer employing phenolic novolak as a main chain as a resist shaped onto the chromium film and an etchant containing a specific quantity or more of nitric acid as an etchant. CONSTITUTION:A chromium film 2 is formed onto an silicon substrate 1 in thickness of 500-5000Angstrom  through a method such as a plating method. A pattern 3 is shaped onto the chromium film 2 through a technique such as a normal photo engraving technique. The substrate 1 is dipped into an etchant. The substrate is etched by the etchant containing 2mol/litre or more of nitric acid at that time. The pattern 3 begins to be peeled by nitric acid in the etchant from an end section while the chromium film 2 is oxidized by an oxidizing agent in the etchant, and peeled and oxidized substances are eluted as ions into the etchant and etching progresses. The reaction simultaneously progresses continuously, thus forming an etching end face in the chromium film 2 to a tapered shape.

The snowfall meter 9 positions the focus of transmitted and received light on a point about 3 meters apart from the snowfall meter 9 and counts the number of snow flakes on the point per unit time, obtaining a snowfall. The thermometer 11 measures the temperature of the measuring surface of the snowfall meter 7 by a pyroelectric type infrared ray detecting element and the thermometer 13 measures an outside air temperature. By executing a calculating and discriminating processing on data thus obtained, information on a variety of road surfaces can be automatically and instantaneously obtained.

Abstract: PURPOSE:To reduce the electrical shock when a discharge lamp is replaced by providing a direct-coupled transformer connected with the other output terminal of a DC power source on one end side of the winding and energizing the discharge lamp with the output across both ends of the winding. CONSTITUTION:The voltage across both ends of the secondary winding, i.e., the high-frequency voltage component generated across both ends (c) and (d) of a direct-coupled transformer 4, is nearly a half of the high-frequency voltage component generated at (d) of the direct-coupled transformer 4, and they are in opposite phases to each other. When the voltage on both ends of the secondary side is added, the high-frequency voltage component equal to that in the past is obtained. A lamp 3 can be high-frequency-lit as before, even if a current flows through a human body when the lamp is replaced, this current becomes nearly a half of the current in the past, thus the electrical shock can be reduced.
