Title: Production of hermetically-coated optical fiber
Inventor: KOMURA YUKIO
IPC: C03C25/42
Filed: 1990-03-22
Abstract: PURPOSE:To improve the quality, to reduce the height of the production device and to increase the line speed by passing the produced film through the oxygen atmosphere and hydrocarbon atmosphere in the second and third chambers to cool the film before being coated with a resin. CONSTITUTION:The optical fiber 3 obtained by spinning an optical fiber preform 1 is immediately introduced into the first chamber 4A of a reactor 4 to provide a hermetic coating layer (L) of amorphous carbon, and the coated optical fiber 3B is obtained. The fiber is introduced into the second chamber 9A of a reactor 9 contg. a gaseous O2 atmosphere diluted with Ar to oxidize and remove the residue of a hot CVD reaction and unreacted product such as C and H deposited on the coating layer L. The fiber 3B is then introduced into the third chamber 13A of a reactor 13 to allow the H2O molecule deposited on the coating layer L to react with the supplied gaseous hydrocarbons such as CH4 in the chamber 9A into CO and H2. Since the reaction is endothermal, the fiber 3B is rapidly cooled. The cooled fiber is introduced into a resin coating device 16, and the resin layer is cured in a curing oven 17.

Title: Geared motor
Inventor: IKEKITA YONEJI
IPC: H02K7/116
Filed: 1999-03-18
Abstract: PROBLEM TO BE SOLVED: To use the same output shaft of a reduction gear by forming the last stage gear attachably, even if the output direction of the output shaft is disposed on either the right or the left side of a reduction gear case. SOLUTION: A final stage gear 9 is formed attachably, even if the output direction of an output shaft 21 is disposed on either of right or left side of a reduction case. The relative position of the final stage gear 9 to a bearing 12 is positioned by a spacer 15, and the relative position of the output 21 to a bearing 13 is positioned by a spacer 22, so that a portion in the reduction gear case can be assembled in the same condition, regardless of the direction of the output side of the output shaft 21. As a result, the same rotating shaft 21 can be used, even if the direction of the output shaft is disposed on either the right or the left side. A bearing-mounting part on a sealing side is reduced in sized so that its diameter is reduced, so that it is possible to eliminate the use of the spacer 22, thereby reducing the number of parts.

Filed: 1998-03-06
Abstract: PROBLEM TO BE SOLVED: To suppress consumption of printing material at the time of printing without sacrifice of image quality by modifying the pattern for decimating a pixel data depending on the direction of a sheet when printing is performed using a save print function. SOLUTION: If a mask pattern is fixed although the same image data is thinned out by using the same mask pattern, the assigning direction of the mask pattern is varied by 90 deg.. Consequently, a mask pattern must be selected such that no change appears even if the mask pattern is turned by 90 deg.. Two types of mask patterns A, B are prepared such that they match with each other upon turning by 90 deg. and one mask pattern A or B is chosen dependently on the carrying direction so that the direction of mask pattern is matched with that of a sheet in any carrying direction thus eliminating difference of image quality.

Title: Optical disk
Inventor: KYODA TAKESHI
IPC: G11B7/24
Filed: 1993-03-31
Abstract: PURPOSE:To provide the optical disk which is hardly electrified and has high scratching resistance and extremely high reliability. CONSTITUTION:This optical disk is constituted by successively forming at least an optical recording layer 2 and a protective layer 3 on one main surface side of a substrate 1. The lower part of this protective layer 3 consists of a resin having <=10% curing shrinkage rate and the upper part of the protective layer 3 consists of a resin having >=2H pencil hardness. As a result, direct application of a stress on the optical recording layer 2 does not arise even if the resin formed on the optical recording layer 2 shrinks. The corrosion of the optical recording layer 2 caused by this stress is prevented as far as possible. The surface of the optical recording layer 2 of the optical disk is the resin layer consisting of hard resin having >=2H pencil hardness and, therefore, the surface has the high scratching resistance. The generation of pinholes on the surface of the protective layer 3 is prevented even if an arc discharge is generated by contact of an electrifying body with a cartridge.

Filed: 1981-05-19
Abstract: PURPOSE:To remove torque ripplet from a DC motor by controlling an armature current in response to the produce of the armature current and a counterelectromotive force. CONSTITUTION:A bridge circuit is composed of resistors 2, 3, 4 and a DC motor 1, and a transistor 8 is connected between output terminals of the bridge circuit. A multiplier 7 multiplies the counterelectromotive force detected by the collector resistor 3a of the transistor 8 by the armature current detected by the resistor 2. When the output voltage of the multiplier 7 exceeds the shifting voltage by diodes 6a, 6b, the collector current of the transistor 6 is abruptly increased so that the voltage drop due to the resistor 5b is abruptly increased. Accordingly, the base voltage of the transistor 5 is lowered, and the voltage applied to the bridge circuit is decreased. In this manner, torque ripple can be removed from the motor.
