IPC: B41J2/055
Filed: 1986-03-11
Abstract: PURPOSE:To prevent the generation of a pressure wave in an ink feeding system disturbing normal printing operation, by respectively opening an ink feeding port to each ink pressurizing chamber. CONSTITUTION:An ink jet head is provided with plural ink pressuring chambers 2, 2..., plural nozzle ports, 3, 3... interconnecting respective ink pressurizing chambers 2, and the piezo vibrators 6 pressurizing the ink contained respective ink pressurizing chambers 2 in accordance with printing data, and an ink feeding port 5 is respectively opened to each ink pressurizing chamber. The ink feeding port 5 is respectively positioned just after the throttle 7 of each ink pressurizing chamber 2 and ink is directly fed to the ink pressurizing chamber 2 from an outer ink tank. Therefore, even though the vibration of a reciprocating motion is transmitted to the ink jet head 1, because any hollow part to amplify said vibration does not exist, any pressure wave due to vibration is not generated in the ink feeding system and only the pressure force caused by the piezo vibrator acts on the ink pressurizing chamber.

Abstract: PURPOSE:To prevent the decrease in cutting ability and the damaging of an arc nozzle in the case of cutting a metallic material by the arc using a non-consumable electrode by controlling the start voltage in the stage of transferring from the pilot arc to the main arc at the specific low voltage. CONSTITUTION:In a plasma arc cutter or TIG welding device which generates arcs by using a non-consumable electrode, a castable 10 is mounted via an insulator 8 to the anode 7 of an arc torch to insulate a nozzle 9 electrically. At the start of the work, a working gas is ejected through the nozzle 9 toward the work 5, after which a pilot arc is generated between an electrode 3 and the nozzle 9 with the low voltage from an electric power source 11. Next, the high voltage from an electric power source 13 is applied to generate a plasma main arc (a) between the electrode 3 and the work 5 with the aid of the pilot arc, whereby the work 5 is cut.

Title: Self-oscillation type semiconductor laser and manufacture thereof
Inventor: MIYAZAKI KOICHI
IPC: H01S5/065
Filed: 1996-02-16
Abstract: PROBLEM TO BE SOLVED: To make the margin for self-oscillation larger and make the self- oscillation level per pellet approximately constant by providing crystal damage regions in at least part of second clad layer in the parts on both sides of a stripe part. SOLUTION: Linear crystal damage regions 10 are provided in a p-type clad layer 4 about symmetrically with respect to the center line of a stripe part 4a thereof. These crystal damage regions 10 are provided so that tips thereof reach to a predetermined depth in the thickness direction of the p-type clad layer 4. A current injected into the p-type clad layer 4 upon operation of a self-oscillation type semiconductor laser is blocked by these crystal damage regions 10 so that it hardly extends further in the lateral direction. On the contrary, the light extends all over the p-type clad layer 4 almost independently of the crystal damage regions 10. Thus, the self-oscillation type semiconductor laser performs self-oscillation. Therefore, the margin for the self-oscillation can be made larger and the self-oscillation level per pellet can be made approximately constant.

Abstract: PROBLEM TO BE SOLVED: To provide a contact key switch conformable to a low resistance value and reduced in cost by using a conductive fabric or conductive nonwoven fabric as the surface of a contact part provided in a part of a key pad of rubber-like elastic body. SOLUTION: For a contact key switch 1 consisting of a non-operation part 1a, an operation part 1b, a thin skirt part 1c, and a downward protruding part 1d which are integrally formed, silicone rubber is preferably used to enhance cold resistance, heat resistance, chemical resistance, precise moldability, and repulsive resilience. As the conductive fabric or nonwoven fabric of a laminate contact part, carbon fiber or metal fiber is preferably used to reduce the resistance. For example, the laminate contact part is formed by laminating a carbon fiber woven fabric on both sides of a conductive unvulcanized silicone rubber sheet followed by compression molding and punching it to a prescribed form after vulcanization, and it is charged in a metal mold, and integrally molded with a key switch body. A jig for specifying both conductive sides of the laminated contact part is not required.  Further, it may be formed by applying or printing unvulcanized rubber to a conductive woven fabric or the like followed by hardening. No adhesion process is required.

Title: Thermal head module
Inventor: TOTSUTA YOSHIHISA
IPC: B41J2/345
Filed: 1989-03-06
Abstract: PURPOSE:To reduce the area of a thin film conductive layer by providing a lead frame of metal having smaller sheet resistance instead of a conventional metal paste thick film on the thin film conductive layer connected to all heat generators in which a large current flows. CONSTITUTION:A pulse current which has passed heat generating resistors 32 flows to a common resistance electrode film 24. The film 24 is connected to a lead frame 108 through a gold thin film layer 102 and a solder 106. The resistance of the frame 108 is much lower than that of the film 24. Thus, a current flows to the frame 108, and flows from a common resistance electrode ground electrode 72 to an external ground. The sheet resistance of the frame is approx. 0.0016OMEGA. On the other hand, the sheet resistance of silver paste heretofore used is approx. 0.050. Accordingly, in simple comparison, the width of the frame may be approximately 1/3 of the width of the silver paste.

Filed: 1997-03-10
Abstract: PROBLEM TO BE SOLVED: To control the movement of clamps so that the clothes are placed at intervals in proportion to the width of each piece of clothes without lapping one another in order to achieve higher throughput. SOLUTION: A piece of clothes caught by a first clamp 14 and a second clamp 14' is kept stretched by the first clamp 14, and which is conveyed by belts 15a, 15b as far as a second clamp 14' is detected by position sensors 19a, 19b. When the second clamp 14' comes upon the piece of clothes, it is connected to belts 15a, 15b after a front part of the piece is released from the stretch. The width of the piece of clothes is determined by the interval between clamps when the second clamp 14' reaches synchronized sensors 20a, 20b. Thus, the clothes are placed at the center of the conveyer throughout all or the half of the conveyer track in proportion to the determined width and the placement observed by a conveyer sensor put adjacently to a stretch device 12.
