Title: Semiconductor device and fabrication thereof
Inventor: OKAYAMA YASUNORI
IPC: H01L21/762
Filed: 1997-09-08
Abstract: PROBLEM TO BE SOLVED: To suppress occurrence of punch-through between a well layer and the source-drain diffusion layer of an element region where skirting is induced even upon occurrence of misalignment of well region by suppressing skirting of the trench side wall at the bottom of an isolation trench structurally. SOLUTION: When trenches 2a, 2b are made using RIE method by making oblique the intersection of an isolation region 2b, intersection angle of the trenches 2a, 2b is set such that the gap is intercepted by element regions 7, 8 spaced apart by the trench 2b when the oblique trench 2b is viewed from the direction perpendicular to the well boundary 5 while traversing the trench 2a from on element region 6 extended straightly in the longitudinal direction, thus minimizing the effect on the shape of the side wall of the trench 2a. According to the structure, skirting can be suppressed structurally on the other side of trench in the isolation region 2a even if the isolation trench 2b is present in one side wall of the isolation trench in the isolation region 2a adjacent to the well boundary.

Title: Device controller
Inventor: KAIDA MASAKAZU
IPC: G05B23/02
Filed: 1996-09-13
Abstract: PROBLEM TO BE SOLVED: To prevent the lapse of unnecessary protecting time when an objective controller is started by deciding a halt protecting time proper for the return of the controller based on the duration of halt time of the objective controller and the state change of a control object device. SOLUTION: An input processing part 2 inputs the state of a control object device, and a time processing part 4 calculates the current time. A power interruption holding storage part 5 stores the state of the control object device and the current time even in a power interruption mode. An output processing part 6 controls the control object device by the output request of an arithmetic processing part 3. A decision processing part 31 of the part 3 compares the halt time and the state information on the control object device which are stored at the part 5 with the starting time and the state information on an objective controller 1 to calculates the halt time of the control object device and then decides the halt protecting time that is proper for the return of the objective controller 1 based on the calculated halt time and the state change of the control object device.  Thus, the lapse of unnecessary protecting time can be prevented even when the objective controller 1 is started.

Title: Toothbrush
Inventor: SUZUKI AKIRA
IPC: A46B9/04
Filed: 1997-09-08
Abstract: PROBLEM TO BE SOLVED: To clean interdental spaces to the back by planting long and short tapered bristles on a bristle base by tufts alternately. SOLUTION: Long bristles 4 and short bristles 5 exhibit their goodness without damaging the goodness by interference because the long bristles 4 and the short bristles 5 coexist on a bristle base 1. Therefore, as both cleaning of interdental spaces to the back and cleaning without damaging the surfaces of teeth and gums can be practiced well, it is possible to clean interdental spaces to the back even if gums have degenerated due to periodontosis such as paradentitis. Tufts 14 where long bristles are planted and tufts 15 where short bristles are planted are arranged in rows. Therefor, cleaning of interdental spaces to the back requires only a small force by adjusting the direction of the rows of tufts and the direction of interdental clearances properly.

IPC: B41J2/05
Filed: 1991-09-24
Abstract: PURPOSE:To make adhesion between a base plate and structural member favorable and prevent influence by a vibration at the time of cutting from exerting on them. CONSTITUTION:An electric and thermal conversion body 8 is provided on one surface of a base plate 1 and a polyimide resin layer 2 is provided on a part with the exception of a discharge port 4, liquid flow path 5 and liquid chamber 6. A structural member 3 is fused to the polyimide resin layer 2 and the base plate 1 and structural member 3 are stuck close to each other through the polyimide resin layer 2. In the polyimide resin layer 2, since fusion properties between the structural member 3 and the same are favorable, the base plate 1 and structural member 3 adhere close to each other. Since the polyimide resin layer 2 possesses elasticity, in the case where after a plurity of amounts of the recording heads are molded in a body, the same is made into the respective recording heads by cutting, a vibration by the cutting is absorbed into the polyimide layer 2.

Title: Filament coil cutting device and cutting edge and fusing electrode edge for filament coil
Inventor: MURATA YOSHIAKI
IPC: H01J9/04
Filed: 1988-09-27
Abstract: PURPOSE:To enable a single cutter to cut various filaments having different wire diameters by causing coil cutting heads and coil fusing heads to be exchangeable for a pair of benches. CONSTITUTION:A pair of coil cutting heads 9, 10 and coil fusing heads to be mounted on a pair of benches 6, 7 are caused to be exchangeable. Accordingly, if a filament coil has a relatively large wire diameter and firmness, it can be cut automatically by mounting the pair of the coil cutting heads on the coil cutter benches. On the other hand, if the filament coil is replaced by a filament having a small wire diameter and no firmness, it can be fused automatically by exchanging the heads for the coil fusing heads. Therefore, various kinds of filament coil can be cut by a single arrangement so that the manufacturing arrangement can be reduced.

Title: Batch type high-frequency drying device and electrode plate to be employed therefor
Inventor: KATAOKA KATSUAKI
IPC: H05B6/54
Filed: 1988-09-27
Abstract: PURPOSE:To uniformize the distribution of electric power and realize uniform drying by a method wherein articles to be dried are put on a fixed electrode plate, acting also as the placing table of the articles to be dried, while a space between electrode plates, opposed at the upper part of the placing table, is regulated by the movement of only a light movable electrode plate. CONSTITUTION:Movable electrode plates 5 are permitted to be moved into up-and-down direction by a driving source provided at the outside of a drying oven 1 through connecting bars 6. On the other hand, fixed electrode plates 4 acting also as a placing table, opposing to the movable electrode plate, are fixed to a frame body 3. The movable electrode plates 5 are supported by connecting bars 6 through pins or the like, however, the movable electrode plates 5 may be supported in slanted or stepped state excluding horizontal condition when the supporting parts are provided with long holes. Accordingly, articles to be dried such as cheese and the like may be put on the placing table used also for the fixed electrode plates 4 while the space of the movable electrode plates 5, positioned at the upper parts of the articles 9 to be dried, may be regulated freely. When the spaces between the electrodes near the power supplying unit of a high-frequency power source especially are narrowed, more improved uniform property of the distribution of voltages may be obtained.

Title: Liquid feeding device equipped with liquid sag preventive device
Inventor: TAKAYA SHIGEAKI
IPC: B65B3/04
Filed: 1991-09-25
Abstract: PURPOSE:To provide a liquid feeding device which prevents liquid sag by cavitation due to the characteristic of a liquid or the thinness of pipelines from generating, and feed a liquid from a nozzle while keeping the initial discharge quantity at the time of re-discharge stable. CONSTITUTION:A discharge control valve 4 is provided between a nozzle 2 which discharges a liquid, and a liquid feeding source 3. Then, a by-pass pipe 11 which goes vertically downward is connected between the discharge control valve 4 and the nozzle 2, and a by-pass valve 12 is connected to the by-pass pipe 11. When the discharge control valve 4 is closed to stop the discharge of a liquid, if the by-pass valve 12 is opened for a desired period of time, which is optionally set while adjusting the timing to the motion, the liquid in the nozzle 2 is dragged in by the weight of the liquid in the by-pass pipe 11, and the liquid is prevented from sagging. The liquid in the nozzle 2 stops right before the tip of the nozzle. Since the action is based on the weight of the liquid, there is no cavitation, and an appropriate drag-in speed can be obtained. Also, at the time to resume the discharge, there is no abnormality in the initial discharge quantity due to air bubbles of cavitation or discharge of a liquid reservoir.
