Title: Electrostatic multiple-needle recording head and manufacture thereof
Inventor: GOMYO MASATO
IPC: B41J2/395
Filed: 1989-10-03
Abstract: PURPOSE:To reduce the amount of resin required for fixing electrode wires, and improve the accuracy of dimensions by a method wherein the electrodes are composed of wire material, spacers are put between two rows of wires, and the two rows of wires are brought into contact with the spacers to keep the distance between them. CONSTITUTION:Two plastic blocks 4 and wires 3 are so positioned that the cross sections of the blocks 4 and the wire 3 are located on a common plane. The wires 3 in a wire block 12 are positioned between the wires 3 in the other wire block 11. The thickness of spacers 8 is equal to L2 minus the diameter of the wires 3, where L2 is the distance between the centers of two rows of electrostatic multiple-needle electrodes. Thus, spacers 8 are placed between the two rows of the wires, and the wires 3 are brought into contact with the spacers 8 so as to keep the distance between the two rows of wires. Thereby, the amount of resin required for fixing the two rows of wires 3 can be reduced, and a high dimensional accuracy can be maintained.

Filed: 1988-10-14
Abstract: PURPOSE:To improve the crystallinity of an active layer and improve the efficiency of a semiconductor laser by a method wherein an InP layer having a thickness about the same as or larger than the height of the peak of a deflection lattice is provided and the surface is levelled. CONSTITUTION:In order to obtain a selected single vertical mode oscillation, a corrugated deflection lattice 2 is provided on an InP substrate 1 and an InGaAsP crystal layer 6 is formed on the lattice 2 by liquid crystal growth so as to have a thickness about a half of the depth of the valley of the deflection lattice 2. Then, in order to reduce the influence of crystal defects existing in the deflection lattice 2 part, an InP crystal layer 7 is built up so as to have a thickness about the same as or larger than the height of the peak of the deflection lattice 2 to level the top surface of the InP crystal layer and an active layer 4 is formed on the InP crystal layer 7. By levelling the surface as described above, the influence from the deflection lattice 2 at the time of forming the active layer 4 can be suppressed and the crystallinity of the active layer can be improved and, by making the thickness of the InGaAsP crystal layer 6 which functions as a light absorber to be thin, the oscillation efficiency can be improved.

Filed: 1999-09-13
Abstract: PROBLEM TO BE SOLVED: To obtain a smooth ink film by transferring an ink to a plate cylinder by an ink transfer roller, and smoothing the ink on the roller by a smoothing unit.

Title: Light control film and production thereof
Inventor: SHIMIZU SHIGERU
IPC: G02F1/13
Filed: 1990-09-28
Abstract: PURPOSE:To obtain a light shielding effect by dispersing a liquid crystal into a high- polymer medium and forming the high-polymer medium by a polymn. reaction, thereby developing a transparent when an electric field is not impressed and a cloudy state when the electric field is impressed. CONSTITUTION:The liquid crystal is dispersed in the high-polymer medium 14. The liquid crystal which has spontaneous polarization and exhibits a chiral nematic phase or chiral smectic phase is dispersed into a polymerizable prepolymer when the liquid crystal exhibits the transparent state at the time of the electric field non-impression and the cloudy state at the time of the impression of the electric field. The polymerizable prepolymer is brought into polymn. reaction in the impressed state of the electric field or magnetic field at which the liquid crystal exhibits the transparent state. The AC electric field of a high frequency is impressed in order to orient the liquid crystal molecules in droplets 16 dispersed in the prepolymer along the electric field (perpendicular to the electrode plane). The liquid crystal molecules remain oriented perpendicular to the electrode plane after the impression of the electric field is stopped when the prepolymer polymerized in this state. The AC electric field of the low frequency at which the spontaneous polarization of the liquid crystal molecules exhibit response is impressed in order to put the film into the cloudy state.

Inventor: FUJITA TAKESHI
IPC: G06F13/00
Filed: 1988-10-14
Abstract: PURPOSE:To reduce the load on a center system without increasing the load on decentralized processors by inhibiting transaction data input to the decentralized processors for a prescribed time when the number of input transaction data per unit time is larger than a prescribed value. CONSTITUTION:A decentralized processor 12 calculates a time value for the suppression of input from an input-only terminal 13 based on input control information sent from the center system 11 and sets the time value as a timer interruption timer value. Further, when a timer interruption is generated, the decentralized processor 12 sends a requires to read one block of data to the input-only terminal 13 and sends inputted data to the center system 11. This processing is repeated until input control information is changed or input control is reset. Consequently, the amount of input data from the input-only terminal 13 can be controlled with input control information from the center system 11 and the load on the center system 11 can be reduced without increasing the load on the decentralized processor 12.

Title: Speed change controller for continuously variable transmission
Inventor: SUZUKI YUTAKA
IPC: F16H61/04
Filed: 1989-10-04
Abstract: PURPOSE:To reduce response delay of a hydraulic device for transmission by providing a correcting means for commanding a preset excessive target value which is excessive in the transmission direction in place of a target value for a predetermined time after transmission is started. CONSTITUTION:For a predetermined time after transmission is started, a target value which is excessive in the transmission direction than a target value acquired from a driving condition is commanded to a transmission actuator by a correcting means. Thus, a hydraulic device for transmission can make a quick response, and in the state that the predetermined time has passed, a deviation between the original target value and an actual value can be made small. Thus, overshoot is not generated in the subsequent transmission control. The same action can be obtained when the above control is carried out for the period till revolution speed of a driving pulley reaches a predetermined value.

Title: Method of heating cooking and heating cooker
Inventor: OZAWA KAORU
IPC: F24C7/02
Filed: 1994-09-30
Abstract: PURPOSE: To prevent the generation of variety in temperature upon heating cooking by a method wherein the output of microwaves from a magnetron is controlled so as to be synchronized with the rotation of a turn table, on which a food to be cooked is put, in a heating cooker, cooking by heating through microwaves. CONSTITUTION: Microwaves, generated from a magnetron 5 provided on the external side wall 3 of a heating chamber 1, are passed through a wave guide 7 and are projected from a projecting port 9 at the upper part of the side wall 3 into the heating chamber 1. When a hood is put on a turn table 11 and inputting operation of a cooking menu is finished, a heating cooker obtains the total amount of heating necessary for the heating cooking from the weight of the food and the content of the cooking. Then, the output of the microwaves is determined properly by a specified formula based on the total amount of heating so that the outputting time of the microwaves from the starting of heating till the finishing time of heating becomes the integral multiple of one turning time of the turn table 11 based on the total amount of heating and, thereafter, the heating cooking is effected.  Accordingly, the microwaves are projected evenly on the concentrical circles of the turn table 11.
