Patent JP-H10146994-A (JP)
Title: Printing method
Inventor: GIBSON BRUCE D
IPC: B41J2/21
Filed: 1997-09-03
Abstract: PROBLEM TO BE SOLVED: To eliminate printing remains such as a color band-shaped part, etc., which generate accompanying the pause of a printer during a normal printing, by a method wherein right after a pause of the printer, an ink jet cartridge assembly is made to scan by going across a medium without making it advance, and a printing is performed on the medium with a magenta ink only. SOLUTION: After a pause of a printer, or a delay period of time, an ink jet cartridge assembly is scanned by going across a paper without making it advance in the advancing direction of the paper, and only a magenta ink is jetted to a scanning line 54 of the paper. Right after the scanning, a cyan ink, the magenta ink and a yellow ink are jetted on the paper respectively, and after that, by scannings 70, 72 and 74, a normal printing is returned. Since the magenta ink is not jetted on the paper during the scanning right before the pause of the printer or a delay period of time, an additional time such as a drying of the magenta ink, and the imparting of an interaction with the paper, does not generate before the cyan is imparted to the scanning line 54.

Title: Electrostatic charge developing toner and image forming method
Inventor: YAMADA HATSUMI
IPC: G03G9/097
Filed: 1996-09-26
Abstract: PROBLEM TO BE SOLVED: To obtain uniform electrification which prevents fog, to improve environmental dependence of picture quality, to improve durability of a developer and to prevent deposition on a photoreceptor or production of image defects by incorporating at least color particles and fine particles containing titanium oxide of specified pH and positive electrification hydrophobic silica. SOLUTION: This electrostatic charge image developing toner contains at least color particles and fine particles containing titanium oxide of pH=6 to 8 and positive electrification hydrophobic silica. When the pH of titanium oxide is higher than 8, alkali is excessive and positive electrification property increases, which makes as a result, uniform dispersion on the toner surface difficult. Thus, no effect is obtd. If the pH of titanium oxide is lower than 6, deposition on a positive electrification part which is present on the toner surface is largely caused, and as a result, uniform dispersion on the toner surface is decreased and no effect is obtd. The titanium oxide is preferably surface treated with an alkyltrialkoxy silane coupling agent.

Title: Laminating device for producing id card
Inventor: MOTOYACHI FUJIO
IPC: G11B5/84
Filed: 1989-09-29
Abstract: PURPOSE:To obtain a uniform pressurizing force over a long period by interposing a pressure equalizing heat-resistant resin sheet between a pressurizing plate and a metallic belt. CONSTITUTION:The pressure equalizing heat-resistant resin sheets 67 and 68 are interposed between the pressurizing plate 28 and the metallic belts 25 and 26. Accordingly, when a pressure is exerted on a card material, the errors in the thicknesses of the belts 25 and 26 and the flatness and parallelism of the plates 28 are absorbed by the sheets 67 and 68, and uniform pressurization is caused without enhancing the precision in working the belts 25 and 26 and plate 28 and the assembling precision. Furthermore, since only the resin sheet is worn, the exchange is relatively easily carried out, and the operation suspending time is reduced.

Title: Throttle valve device for internal combustion engine
Inventor: TANAKA KUNIO
IPC: F16K47/00
Filed: 1999-09-09
Abstract: PROBLEM TO BE SOLVED: To remove material with high viscosity in which soot, lubricating oil and unburnt fuel are mixed by providing a spitting flow restrain part for restraining the direction of spitting flow on the downstream surface of a valve element of a throttle valve. SOLUTION: When a throttle valve 11 is substantially in the state, a spitting flow reaches the throttle valve 11 and then flows toward the outer periphery of a valve element along the downstream surface 13a of the valve element 13 of the throttle valve 11 to collide with the inner surface 2a of the circular-arc barrier 2. By the barrier 2, the flow directing toward the outer periphery of the valve element 13 is bent toward the downstream of an intake passage 10 to be remote from the throttle valve 11. Simultaneously, deposit carried by spitting flow collides with the inner surface 2a (deposite storing part) of the barrier 2, adheres thereto and deposits thereon to be captured. Thus, the deposit carried by spitting flow is kept apart from the throttle valve 11 by the barrier 2, or captured on the inner surface 2a to thereby prevent adhesion and deposition to the outer peripheral part 13b and the portions opposite to the outer peripheral surface.

Title: Pal system video camera apparatus
Inventor: TATSUMI SHINGO
IPC: H04N9/04
Filed: 1992-08-31
Abstract: PURPOSE:To simplify the constitution of a band limiting filter and the constitution of a printed board, to reduce cost and to provide improved picture quality without noise by making a driving frequency for a 1H delay circuit for signal processing the same frequency as the frequency of horizontal transfer pulses for a solid-state image pickup element. CONSTITUTION:The clock of fck obtained from a driving circuit is used as the driving pulse of a 1H driving circuit used inside a 2H enhancer 9 and the 1H delay circuit 6 for the signal processing. That is, since the sampling clock of the solid-state image pickup element and the sampling clock of the 1H delay circuit 6 for the signal processing are made coincident as fck, no clock component is present in a frequency area lower than the sampling clock of the 1H delay circuit 6 and only signal components are present. In such a manner, since no source signal to be folded is present, foldover noise is not generated. Thus, the constitution of the band limiting filter in a front stage is simplified and also the constitution of the printed board is simplified.

Abstract: PURPOSE:To allow an optical sum of products operation to be executed in parallel and to obtain a large-scale neural network by disposing a light emitting element which allows optical writing and photodetector which allows electrical writing in orthogonally intersecting directions. CONSTITUTION:This device consists of a pair of Schottky electrodes 11, 12 formed on a semiconductor 2. A voltage of a negative polarity for writing is impressed to the control electrode 11 and a photoirradiation region is irradiated with writing light 4 at the time of a writing operation. A current of a positive polarity flows to the output electrode 12 at this time. The photoirradiation region is irradiated with reading out light 5 without impressing the voltage to the control electrode 11 at the time of a reading out operation. The current of the polarity reverse from the polarity at the time of the writing flows to the output electrode 12 at this time. The number of the carriers generated at the time of the writing depends on the bias voltage and the intensity of the writing light 4 and the space charges by the trapped carriers depend on the number of the carriers generated at the time of the writing and, therefore, the intensity of the writing light 4 is stored as the analog data in the form of the space charge into an MSM photodetector.
