Patent JP-H0226776-A (JP)
Title: Serial printer
Inventor: UENO SHIGETO
IPC: B41J29/02
Filed: 1988-07-18
Abstract: PURPOSE:To miniaturize the title printer by fixing a flexible printed circuit board to the upper end part of the side surface of a carriage so that the end of said circuit board is turned in a horizontal direction. CONSTITUTION:The FPC 11 fixed to the center of the bottom surface of a chasis 7 at the terminal thereof is fixed to the left side surface of a carriage 3 by a clamp roll 12 and goes along the under surface of the carriage 3 to issue to the upper surface of said carriage 3 from the central part thereof to be connected to a printing head 1. The printing head 1 having the FPC 11 connected thereto is fixed to the leading end of a head arm 13, which is also used as a heating plate, pivotally supported in a freely revolvable manner by the carriage 3. The pinion 14 meshed with the rack fixed to the chasis 7 and the gear train transmitting the rotation thereof to a reel stand 15 are received in the carriage 3. By this method, the radius R of curvature of the bending part fixed to the upper end of the side surface of the carriage in a horizontal direction of the FPC can be made sufficiently large. Therefore, the trouble of the flexible printed board sending a printing signal to the printing head is reduced and a serial printer can be miniaturized.

Title: Method for welding hollow cylindrical members
Inventor: SANPEI KAZUHISA
IPC: B23K26/21
Filed: 1987-07-17
Abstract: PURPOSE:To prevent a weld crack taking place on a weld bead by fitting members to be welded one of which at least is hollow cylindrical on the fitting surface and forming the abutting surface on the tapered surfaces each other and sticking these fast to each other to weld the tapered surfaces together with the high energy heat source. CONSTITUTION:One member 1 to be welded at least of two members 1 and 2 to be welded is formed to the hollow cylindrical member and both the members 1 and 2 formed to the hollow cylindrical member and both the members 1 and 2 to be welded are fitted on the fitting surface 12 and butted on the abutting surface 13. At this time, the abutting surface 13 is formed to a taper in the direction to approach the outside surface as it proceeds to the edge 14 of the member 1 to be welded. Both the tapered surfaces 13 of both the members 1 and 2 to be welded are butted so as to be stuck to each other. Next, a laser beam 3 from the high energy density heat source such as the laser beam, etc., is projected on a welding surface zone made of the tapered surfaces 13 and the members 1 and 2 to be welded close to the welding surface are molten and solidified and both the members to be welded are joined at the tapered surface 13 part. The weld bead 15 with the depth of penetration and bead width of relatively small sizes is formed and the thermal contraction stress to act on the bead at the time of solidifying is relaxes and averaged and the occurrence of the weld crack can be reduced by forming the welding surface to the tapered surfaces 13.

Title: Internal combustion engine and performance improving method thereof
Inventor: HARING JOHN MCMASTER
IPC: F02D41/40
Filed: 1991-06-21
Abstract: PURPOSE: To substantially reduce or eliminate pollutants by providing a combustion process having a combustion passage of time substantially at a constant pressure over the period of a minimum crank angle of 45 deg. after a top dead point so as to improve performance of an internal combustion engine. CONSTITUTION: Compressed cooling air from a cooler 26 is introduced to the compression cylinder 28 of an engine 20, here the air is cooled again and then introduced to a combustion chamber, i.e., a cylinder 32. Then, products from combustion are introduced through an exhaust manifold 34 to expansion cylinders 36 and 38, then sent to a serge chamber 40, and then exhausted through the inside of a compressor 24. Thus, since a combustion process having a combustion passage of time substantially at a constant pressure for over the period of a minimum crank angle 45 deg. after a top dead point is provided, a compression ratio is reduced, and a combustion temperature is set substantially equal to an NOx forming temperature. Also, since energy release is controlled, pollution, both chemical and heat to the atmosphere is greatly reduced.

Title: Method of cleaning piping
Inventor: ESUMI ASAO
IPC: B08B9/02
Filed: 1987-07-17
Abstract: PURPOSE: To facilitate operation and to improve working efficiency by passing ice grains or liquid contg. the ice grains into a pipe and cleaning the pipe by utilizing a vacuum suction system or pressurization system or the like. CONSTITUTION: In the case of cleaning by using the vacuum suction system, a suction device 2 is connected to the end of a suction hose 4 connected to the large-diameter side of the piping 1 to be washed within a building to maintain the inside of the pipe at a vacuum. Next, the ice grains or the liquid 3 contg. the ice grains is sucked through a flexible hose 5 from the one small- diameter side into the pipe where the liquid is passed. At this time, the water contg. the ice grains is first sucked and thereafter, the ice grains are mainly sucked and the inside of the pipe is successively washed from the small-diameter side toward the large-diameter side. Even the intricate piping systems and even the piping of any diameters are thus efficiently washed without clogging.

Title: Switching regulator
Inventor: SATOU TERUYUKI
IPC: H02M3/28
Filed: 1983-09-28
Abstract: PURPOSE:To reduce a voltage applied to the collector-emitter voltage of a transistor to high input voltage by controlling a current of a semiconductor element in response to an exciting energy, thereby regulating a reset time. CONSTITUTION:Exciting energy stored in the primary winding of a transformer during ON period of a transistor Q1 is absorbed to a capacitor C1 through a diode D1 when the Q1 is turned OFF, a current is flowed to R2 by the collector current in response to the base current of a transistor Q2, and the exciting energy is absorbed. When the exciting energy is large, a collector current is increased and flowed, a flyback voltage is reduced, and a reset time is increased. When the exciting energy is small, the collector current is reduced, the flyback voltage is raised, and the reset time is shortened. Thus, the reset time is controlled in response to the amplitude of the input voltage.

Title: Mounting and removing device for live printed wire board
Inventor: OKAJIMA YOSHINORI
IPC: H05K7/14
Filed: 1991-06-25
Abstract: PURPOSE:To see that there is no fear of its breaking data even if one performs the live extraction of a desired card by making it indicate that the printed board can be mounted on or removed from a connector circuit only in the case that the printed board is not performing the data transfer with the specified circuit via the connector circuit. CONSTITUTION:This is provided with a switch means 13 which changes it over between the condition that the transfer of the data between the circuit of a specified printed board 11 and that of a printed board other than this printed board 11 is possible and the condition that it is inhibited. Furthermore, this is provided with a means 14 which indicates that the specified printed board 11 can be mounted on or removed from a connector circuit only when this switch means 13 is set to inhibition and that this is not performing data transfer between the circuit of the specified printed board 11 and the circuit of this printed board. Hereby, one does not get into the extraction work, looking at the lighting condition of a lamp, while the printed board is accessing an external circuit, so one never performs the operation as breaking the data.
