Title: Method and device for eliminating noise of binary picture
Inventor: MARUYAMA TSUGUHITO
IPC: G06T5/00
Filed: 1989-03-20
Abstract: PURPOSE:To efficiently and rapidly eliminate a noise by successively eliminating the noise of an unprocessed picture element while updating binary picture information with the use of a noise elimination processing result by means of a window. CONSTITUTION:When the whisker-like noise, etc., are eliminated, the binary picture information is set in a register group 21, based on the binary picture information. A logical condition is decided by a logical processing circuit 22, and the tip point of a barb is noise-eliminated by a window processing. Further the noise elimination processing result is fed back to the register group 21, and set to a register group 21b corresponding to the processed picture element. Consequently, when the noise of the next attention picture element is eliminated, the picture element information obtained as the result of the noise elimination processing as the binary picture information of the peripheral picture element can be reflected. Thus the whisker-like noise, etc., can be rapidly and efficiently eliminated.

IPC: B41J11/00
Filed: 1990-03-20
Abstract: PURPOSE:To prevent a jam of paper from occurring by a method wherein a clearance equivalent to not less than a reverse line feed quantity which is allowable at one time is provided to rotation of a pinch roller. CONSTITUTION:When paper is drawn out, a gear 22 is driven with a line feed motor via a connection gear 26 to be rotated clockwise, and a shaft 21 is driven with the gear 22 via a pin 23 to be rotated in the same direction. By rotation of the shaft 21, a pick roller 5 is also rotated in the same direction, and the paper is drawn out. The drawn out paper is carried to a printing start position and thereafter, printing is started. When reverse line feed is required in process of printing, reverse line feed is performed by rotating the line feed motor by a specific quantity. For a position of a boss 24 when this reverse line feed is ended, a rotary angle theta1 of the gear 22 is less than a clearance theta. When normal line feed is performed thereafter, rotation of the pick roller is delayed by the reversely line fed angle theta1. Then, through reverse line feed is repeated in a sheet of paper, sagging of the paper is not accumulated, and a jam of the paper can be prevented from occurring.

Title: Circuit adapter device
Inventor: KATOU HIDEO
IPC: H04L29/06
Filed: 1981-05-07
Abstract: PURPOSE:To reduce loads on the software of an electronic computer itself and a work station by connecting a local/remote interface between a high-speed and a low-speed communication circuit. CONSTITUTION:After a power source is turned on, a main controller 57 starts a low-speed communication controlling circuit 53 to hold reception in readiness. In this state, when the controlling circuit 53 receives information transferred from the side of an electronic computer body 21, the information is written in a storage device 53. Once this writing ends, the main controller 57 drives a high- speed communication controlling circuit 54 to transmit a request for transmission. The high-speed communication controlling circuit 54 reads the information out of said storage part 55 and sends it to the side of a local interface 52. Since this interface 52 performs high-speed serial transfer, the transfer ends immediately and the completion of the transmission is reported to the main controller 57. Then, the main controller 57 places the high-speed communication controlling circuit 54 in a reception-enabled state and waits for answers from work stations 251-25n.

Title: Assembling method for suspension
Inventor: AKIYAMA OKITOMO
IPC: B23K26/21
Filed: 1989-03-23
Abstract: PURPOSE:To save waste by reducing a part where no flexure is formed on a metallic plate and to be eliminated by etching or press by effectively forming and using the flexure smaller than a load beam. CONSTITUTION:A large number of flexures 2 are provided by coupling their one ends with the metallic plate. When the tip of the load beam 1 is abutted with the flexure 2 to perform laser spot welding, they are held fixedly. Namely, the utilization of the metallic plate with saving the waste can be attained by abutting a remaining flexure 2 with the tip of the next load beam 1 by moving the metallic plate coupled with the flexure 2 rightward and leftward after the tip of the load beam 1 is abutted with the flexure 2 and applying the laser spot welding. At such a case, it is advantageous to the abutting of them to also set the flexure 2 with the equal intervals since the load beam 1 is provided with equal intervals. In such a way, it is possible to reduce the part where no flexure 2 is formed on the metallic plate and is to be eliminated by the etching or the press.

Abstract: The production of food grade quality white mineral oils from predominantly naphthenic or cycloparaffinic crude distillates heretofore have required acid treating using sulfuric acid followed by neutralization, water wash and possibly finishing step. Herein, however, three stages of hydroprocessing without any solvent extraction or acid treatment prior step are employed to produce the desired food grade quality white mineral oil having a trace of aromatic constituents therewithin. Specific steps are defined in the application in terms of the severity of the hydrogenation in the hydrotreating operation at each respective step; as well as the steps of separating gaseous constituents of the hydroprocessing product.

IPC: H01B5/08
Filed: 1989-03-22
Abstract: PURPOSE:To avoid fusion of a wire material at the time of ground discharge so as to reduce the damage by coating, with a ceramic layer, at least one region of the outer periphery of a strand used for an overhead power transmission system such as a transmission wire, an overhead earth-wire and an optical fiber ground wire. CONSTITUTION:For a transmission wire, there is used a wire composed of a strand of 7 Zn plating steel wires 1 in the center and 12 ceramic coated aluminum wires 2 are twisted on the outer periphery thereof. That is, the peripheral surface of the aluminum wire 2 is coated with a ceramic layer 3 having a composition of 50wt.% Al2O3 -50wt.% ZnO. Thus, at the time of ground discharge, the heat thereof is shielded with the layer 3 so that the wires 2 or 1 are unsusceptible to the heat, thus preventing fusion of the wires. For an optical fiber ground wire, an aluminum made pipe 4, storing an optical cable 5 with a space between the same and the inner periphery, is surrounded with an aluminum coated steel wire 6 and on the surface thereof ZrO2 is applied by thermal spraying, to thus obtain the ceramic layer 7.
