Title: Paper carrier mechanism in thermal printer
Inventor: SHIMIZU MASAHIKO
IPC: B41J15/16
Filed: 1999-12-03
Abstract: PROBLEM TO BE SOLVED: To solve such a problem of a conventional thermal printer, which prints out information on a sheet of paper supplied by a grip roller and held between a thermal head and a platen roller in an upstream area from the grip roller in the sheet carrier direction, that when the thermal head and the platen are separated away to put a sheet of paper back during multicolor printing, the sheet bends between the grip roller and the thermal head and cannot return to the original position between the thermal head and the platen roller, causing discordance in colors. SOLUTION: A pair of tension rollers are provided upstream of a thermal head. Contact points between a grip roller and a pinch roller, between the thermal head and a platen roller, and between the two tension rollers are not located in a straight line. The holding force of the tension rollers is weaker than that of the grip roller. When a sheet of paper is held at the thermal head, the grip roller and the tension rollers separately hold the sheet.

Title: Direct melting furnace
Inventor: ABE KAZUHIKO
IPC: F23G5/24
Filed: 1997-11-28
Abstract: PROBLEM TO BE SOLVED: To obtain a direct melting furnace which can stably perform gasifying melting treatment on rubbish by always forming a dome of a firm compact layer in the lower section of a thermally decomposing zone. SOLUTION: A direct melting furnace is constituted in a vertical shaft furnace in which a drying zone, a thermally decomposing zone 21, and a burning and melting zone 23 are successively formed toward the bottom of the furnace from a rubbish throwing-in port by providing the charge port through the top or side wall section of the furnace and connecting an oxygen-containing gas introducing pipe 25 to the bottom section of the furnace. In the furnace, the bottom section 22 where the burning and melting zone 23 is formed has a cross- sectional area smaller than that of the overlying thermally decomposing zone 21 and, a large shelf section 27 which is inclined from the plumb line at a large angle is formed between the bottom section 22 and the lower section of the thermally decomposing zone 21.

Title: Connector
Inventor: MACHIDA YUKIFUMI
IPC: H01R13/629
Filed: 1995-12-08
Abstract: PROBLEM TO BE SOLVED: To connect a first housing to a second housing from a shifted position. SOLUTION: A reinforcing plate 28 having rigidity is buried in a first housing 21, first connecting terminals 25 are housed in terminal housing grooves 29 formed on the upper and lower surfaces of the first housing 21 so as to expose contact parts 25b. A second housing 22 has a housing receiving chamber 42 for receiving the first housing 21 with a space, second connecting terminals 27 are housed in the terminal housing chambers 41 of the second housing 22 in such a manner that movable contact pieces 35 are swollen into the housing receiving chamber 42. Since the reinforcing plate 28 is buried in the first housing 21, the first housing 21 prevents the deformation of the first connecting terminals 25.  Thus, when the first housing 21 is connected to the housing receiving chamber 42 from a shifted position, the first housing 21 deflects one movable contact piece 35 by the rigidity, and the elastic force of the movable contact piece 35 corrects the direction of the housing 21.

Title: Wire bonder
Inventor: OZAWA ATSUSHI
IPC: H01L21/60
Filed: 1993-12-20
Abstract: PURPOSE:To form a ball so as not to have the center of the ball eccentric to a capillary. CONSTITUTION:A protrusion 3b made of highly conducting material is provided on the upper plane of a torch electrode 3' and, further, a transfer mechanism 8 which positions the tip of the protrusion directly below the wire guide hole 9 of a capillary 2 which holds a bonding wire 1 is provided. As the protrusion 3b is provided on the discharge plane of the torch electrode 3' and the discharge position is always the tip of the protrusion 3b, if the bonding wire 1 protruding from the tip of the capillary 2 is bent so much as to be the cause of producing a club ball, the distance between the tip of the bonding wire 1 and the discharge position becomes large and the discharge is not induced or the discharge current is reduced (or a voltage is elevated). By monitoring the status of the current, the defective ball formation is detected and the bonding operation is discontinued, so that the formation of the club ball can be avoided.

Title: Semiconductor device and its manufacture
Inventor: ODA NORIAKI
IPC: H01L23/52
Filed: 1991-12-27
Abstract: PURPOSE:To prevent increase of contact hole resistance of an upper layer wiring connected with a lower layer wiring via an aperture part of an interlayer insulating film, and short circuit between adjacent wirings. CONSTITUTION:By forming a silicon oxide film 9 on the side wall of an aperture part formed in a polyimide based resin insulating film 7 on a lower layer wiring, it is avoided that a TiW film 10 arranged under the upper layer wiring connected with the lower wiring comes directly into contact, in the aperture part 8, with the polyimide based resin insulating film 7 being an organic interlayer insulating film. Thereby it is prevented that the TiW film 10 is oxidized by moisture from the polyimide based resin insulating film 7, volume expansion is generated, and imperfect contact and short circuit between adjacent wirings are caused.

SOLUTION: A plate-like deformation preventive metal plate 30 sealed at mold molding time is arranged inside a bottom plate part of a component- holding part 11 of an insulator 10. A dimension of the deformation preventive plate 30 is set so as to withstand deforming force of the insulator 10 in a reflow soldering process, to thereby prevent deformation even on a warp and a twist of the insulator 10 at normal temperature time to prevent the occurrence of connecting failure between a contact 20 and a pad 202 of a mounting base board 200 and also the occurrence of contact failure by keeping smoothness between the contact 20 and a contact of an electronic component held in the component holding part 11.

Abstract: PURPOSE:To improve the reliability of optical parallel transmission by sending information while avoiding a transmission line having a fault when the fault takes place in the optional transmission line so as to minimize a delay in data transmission due to the fault. CONSTITUTION:A monitor means 4monitors an optical transmission line 9 outputted from an electrooptic conversion means 2 and detects the occurrence of a fault of an n-th channel, then informs it to a control means 5. The means 5 controls a 1st line changeover means 1 to output channel data outputted to an n-th channel electric transmission line 8 to a transmission line 8 of a redundant channel in an idle state among (n+m) channels. Then the control means 5 controls a 2nd line changeover means 3 to output channel data to be sent through a transmission line 9 of the redundant channel to an optical output data series 7 of the n-th channel. Thus, the data of the n-th channel having a fault are outputted via the redundant channel and the delay in data transmission due to the occurrence of the fault is minimized.

CONSTITUTION:A valve mechanism 2 provided for intake and exhaust ports of an engine 1, is operated for opening and closing by a hydraulic drive part which may be changed over between an all engine cylinder mode in which valves of all engine cylinders are opened or closed, and a partial engine cylinder mode in which valves of only a part of the engine cylinder are opened and closed (valves of the remainder engine cylinder are rested), since the operating configuration of the mechanism 2 is set by a control part 3. The control part 3 sets the all cylinder mode or the partial cylinder mode in accordance with outputs from an engine rotational speed sensor 4 and a boost cylinder pressure sensor 5, being based upon a map. In this case, when the all engine cylinder mode is changed over into the partial engine cylinder mode, the replenishment of air volume is carried out by an idle speed control(ISC) mechanism 7, and the degree of retardation of the ignition timing is set, thereby it is possible to restrain the output torque caused by variation in intake-air volume.
