Title: Self-routing switch network
Inventor: OKAMOTO SATOSHI
IPC: H04Q3/00
Filed: 1989-02-06
Abstract: PURPOSE:To prevent the delay of a cell caused by a network by devising a network such that an input cell can bypass a unit switch in a decentralized network as necessary. CONSTITUTION:A unit switch module(SWM) 10 is provided ports 201, 202, output ports 203, 204 and a bypass ling 205. Then a bypassing collation pattern set to its own unit switch is collated with the bypass tag 22 of an input cell 20a as to the input cell 20a inputted from the input port 201, and when they are coincident with each other, the input cell 20a is sent to a routing network through a bypass link 205 and when they are decorating, the cell is sent to the post-stage of the decentralized network. Thus, even when the number of stages of switches in the switching network is increased, the delay in the switching network is not increased.

Title: Clothing drying machine with shrink preventing function
Inventor: MITO CHIHO
IPC: D06F58/02
Filed: 1999-02-05
Abstract: PROBLEM TO BE SOLVED: To provide a clothing drying machine with shrink preventing function capable of drying clothing while completely fixing it on optimum conditions without shrinking it. SOLUTION: A clothing drying machine 1 with shrink preventing function has a rotary drum 3 for internally housing the clothing to be dried inside a housing 2. Inside the rotary drum 3, a fixing net 20 having gas permeability is equipped for fixing the clothing so as to spread it within a plane crossing the rotation center line of the drum. Since a centrifugal force generated when rotating the rotary drum 3 is not directly applied to the wide surface of the fixing net 20, the vibration and deformation of the fixing net 20 are extremely small so that almost no gap is generated between the fixing net 20 and the clothing. Thereby, the clothing is surely dried while being spread and is hardly shrunk.

Title: Laser welding
Inventor: YANO MASAO
IPC: B23K26/21
Filed: 1978-03-15
Abstract: PURPOSE:A first laser exposing means is used to oxidize the butting portion of welding materials. A second laser exposing means is used to welding. Both laser means are arranged in parallel and relatively moved, thereby to effect an efficient, locally- limited, uniform welding. CONSTITUTION:Laser beam is partly reflected by the half mirror 11 and the revolving reflector 2 to focus into a micro-laser spot which is scanning in a circular trajectory. Such laser spot is impinged on the butting face 6 of the materials to be welded to form oxidized surface in advance. The remainder of the laser beam is passed through the half mirror 1 to concentrate on the preheated, oxidized surface 6 of the materials. Thus, high energy is sufficiently provided to the butting portion 6 of the material 4 to be welded together. Both laser radiating means are moved at the same speed, thereby to effect uniform laser welding efficiently.

Title: Wire exhausting device for wire-cut electric discharge
Inventor: UMETSU MASAHITO
IPC: B23H7/10
Filed: 1988-02-10
Abstract: PURPOSE:To control variation in the torque applied to a wire and prevent wire severance by furnishing a constant-torque speed adjusting mechanism in the drive system for a wire exhausting roller installed behind a transport belt mechanism to carry out the used wire. CONSTITUTION:A constant-torque speed adjusting mechanism 57 such as powder clutch and hysterysis clutch is arranged between the drive roller 55 of a wire exhausting roller 37 and a gear 51 of driving device 47. When therein a wire 27 fed by a transport belt 35 is exhausted by the wire exhausting roller 37, this speed adjusting mechanism 57 installed thereon absorbs slip in an amount corresponding to the speed difference even though a difference is generated between their feed speeds because of wear etc. of the transport belt 35. This enables keeping the wire tension between the rollers 53, 55 constant always to contribute to prevention of the wire from severance.

Abstract: PURPOSE:To automatically execute a previous warning for replacing a battery of a  no-break electric power source by a specified reference, so that the battery can be  replaced suitably, by comparing the battery voltage of the no-break power source with  the reference voltage, when an electric power source of an information processing  system is turned on. CONSTITUTION:A battery circuit 2 being a no-break power source always supplies  electric power to a no-break load circuit 4. When a power source of an information  processing system is turned on, a reference voltage circuit 3 sets reference voltage and  supplies this voltage to a voltage comparing circuit 6 through a connecting line 14. A pulse generating circuit 1 generates a pulse constant time length in accordance with a  power source turn-on signal, and supplies it to a connecting circuit 5. In response to  supply of this pulse, the connecting circuit 5 supplies battery voltage to the voltage comparing circuit 6 through connecting lines 13, 15 for a constant interval of time. The  comparing circuit 6 compares the supplied battery voltage with the reference voltage,  and when the battery voltage is lower than the reference voltage, an abnormal state signal is supplied to the outside through a connecting line 16. In this way, the battery  of the battery circuit 2 can be used until it becomes below the reference voltage.

Title: Weaving method in fluid-jetting weaving machine
Inventor: MURAMATSU MASAYUKI
IPC: D03D47/28
Filed: 1989-02-10
Abstract: PURPOSE:To conduct proper weaving operation without weft missing and yarn breakage by detecting the time when the weft reaches to the opposite side and changing the opening curve on the basis of the detection. CONSTITUTION:A photocell as a weft feeler 7 is set on the opposite side of the weft route to detect the arrival of the weft and output the signal and know the time when the weft reaches on the opposite side. In the case that the timing of the shuttle arrival to the opposite side is delayed, the opening curve is changed to make the opening speed slow so that the weft may not be caught by the cloth. Then, the opening speed is increased up to the normal timing whereby adverse effect on the quality of woven cloth is inhibited.

Abstract: PURPOSE:To reduce the size, the price and simplify the handling and relax the restrictions on the conditions of use by installing a light projection lens which enlarges a light projection spot in the passable width direction of a material to be detected from a direction which perpendicularly intersects the light projection spot. CONSTITUTION:A light projection lens 1 is lengthened in a semicylindrical shape, and a plurality of light emission diodes 2, 2,...
