Title: Ink jet head cleaning liquid
Inventor: ODA HAJIME
IPC: B41J2/175
Filed: 1990-09-05
Abstract: PURPOSE:To improve a recording reliability by a method wherein a cleaning liquid is composed of a mixture liquid of at least an organic solvent, a surfactant, and water. CONSTITUTION:As an organic solvent, alcohol or glycol ether is used, and especially ethanol, isopropyl alcohol, and the like are effectively used. As a surfactant, a nonionic surfactant having a high specific resistance is used by taking an electric safety into consideration because it is to be sprayed on the surface of an ink jet head. As water, pure water is used. The kind and mixing ratio of these three liquids depend on the kind of ink in use and the structure and action of a cleaning device. However, it is desirable that the ratio of the organic solvent is as low as possible in view of a safety to human bodies and a prevention of a firing hazard. In addition, because the main ingredients of the surfactant remain on the surface of the ink jet head after cleaning and drying, it is also required that the water should be contained as large as possible to prevent the ink jet head from being adversely affected.

Title: Display element
Inventor: YOSHINAGA KAZUO
IPC: G02F1/137
Filed: 1990-09-10
Abstract: PURPOSE:To obtain a sufficient transmitted light quantity and a good contrast by providing a display layer contg. a uniaxially oriented high-polymer liquid crystal compd. between a polarizer and a circular polarization splitter. CONSTITUTION:This display element is constituted by providing a display layer 3 contg. the uniaxially oriented high-polmer liquid crystal compd. between the polarizer 7 and the circular polarization splitter 8. Particularly one sheet of the polarizer 7 is merely necessitated as the retardation of the display layer 3 is lambda(m+ or -1/4) (m is an integer contg. 0, only +1/4 when m=0, lambda denotes a visible light wavelength) with respect to visible light. In addition, the light passes just once and, therefore, the transmitted light quantity is sufficient and the film thickness of the display layer is decreased. The degradation in the contrast is thereby prevented. The angle between the plane of polarization of the polarizer and the orientation axis of the display player is preferably 35 deg. to 55 deg.. The incident linearly polarized light is not polarized to the perfect circularly polarized light and the leak light is generated if the angle is off the 35 deg. to 55% range. The contrast is then degraded and such degradation is undesirable. The display element is more preferably used at 45 deg..

Title: Print member driver
Inventor: HIROTA YOSHIHISA
IPC: B41J9/42
Filed: 1986-10-06
Abstract: PURPOSE:To improve the print quality, by providing a driver for producing a second drive pulse which slows down with resetting speed of a print member after the print member collides against a recording medium and before resetting to an initial position and for applying said pulse onto a solenoid. CONSTITUTION:At a time point when a print wire collided against a recording medium through an ink ribbon and finished recording and being reset to an initial position through the reaction of collision and a spring force, a delay circuit DL1 outputs a H-level signal to a transistor Tr1. Consequently, the transistor Tr1 is turned ON and current having a waveform shown on the drawing flows to a drive coil S1 so as to apply brake against the reset motion of the print wire. At a time point when a predetermined time elapses, the delay circuit DL1 is brought to L-level. In other word, force is applied in reverse direction onto the print wire which is reset with high speed upon finish of recording to slow down the speed so as to reduce bound at the initial position, thus achieving high print quality.

Title: Method and device for logical simulation
Inventor: SHIMIZU HIROOMI
IPC: G06F11/25
Filed: 1990-09-07
Abstract: PURPOSE:To prevent a logical simulation from getting into an infinite loop by carrying out the simulation of such a circuit model that has a feedback and also ending forcibly a repetitive execution loop when the feedback has oscillations. CONSTITUTION:When a feedback FB has oscillations, the input of a level A changes and a level return request 31 is produced. A simulation control part 1 receives the request 31 an updating a present loop recognizing part 13. Then a loop comparing part 15 compares the part 13 with a precedent loop recognizing part 14 and decides the same loop. Thus the value of a loop executing frequency counter 16 is increased. The value of the counter 16 is compared with the loop executing frequency limit value 17 at a loop execution granting part 18. When the value of the counter 16 reaches a prescribed limit level, the request 31 is not granted and the loop execution is forcibly ended. Thus it is possible to prevent the infinite execution of a repetitive execution loop.

Title: Semiconductor element having quantum structure and manufacture thereof
Inventor: WESTWATER JONATHAN
IPC: H01L29/06
Filed: 1998-08-24
Abstract: PROBLEM TO BE SOLVED: To surely manufacture a semiconductor element and uniformly manufacture a quantum structure with high reproducibility by forming a protrusion on the side of a semiconductor island in a semiconductor part and by constituting the side of the protrusion of a face, whose oxidation speed is faster than that of the side of a semiconductor island. SOLUTION: A semiconductor layer 12 is etched to oxidize a periphery of a pillar-like semiconductor at the center, and a protrusion 4 of the pillar-like semiconductor is isolated by an oxide film insulator 15, to form a semiconductor island 16 isolated from a semiconductor part of the protrusion 4 at a part of the center of the pillar-like semiconductor. At this time, due to the oxidation rate from the side of the protrusion 4 being fast, the oxidation on a small diameter part on the upper part of the protrusion 4 is caused to advance so as to go across the pillar-like semiconductor. The upper end of the protrusion 4 of the pillar-like semiconductor is pinched off by the oxide film insulator 15 to form a pinched-off part 15p. Thus a quantum structure can be manufactured with high reproducibly and uniformity.

Filed: 1996-09-09
Abstract: PROBLEM TO BE SOLVED: To suitably control thermal crown of hearth roll and to prevent the development of meandering of a strip at the heating zone by securing the strip temp. at the center in a heating zone to the strip temp., in which the temp. difference along the hearth roll axis is not always developed. SOLUTION: At the time of calculating the setting furnace temp. in the heating zone so that the temp. of the strip charged into the continuous annealing furnace at the outlet side of the heating zone reaches a target strip temp., the heating zone is divided into the first half zone and the latter half zone. In the first half zone, the setting furnace temp. is calculated so that the strip temp. at the center of the heating zone is not developed to the temp. difference along the axial direction of the hearth roll and also, the strip temp. reaches a prescribed value according to the width and the thickness of the strip. The temp. of the strip is raised to the prescribed value or higher and the temp. of the part of the hearth contacting with the strip is raised.  By this method, it is prevented that the thermal crown of the hearth roll forms the recessed shape and the meandering of the strip is developed, to improve the working rate and the yield of the equipment.
