Patent JP-H0324963-A (JP)
Title: Ink jet head
Inventor: MATSUMOTO KAZUAKI
IPC: B41J2/055
Filed: 1989-06-22
Abstract: PURPOSE:To make it possible to stably deliver ink from a nozzle by providing an ink passage to feed ink to a means for delivering ink droplets from an ink storing section near the boundary between an ink holding body and the ink storing section. CONSTITUTION:The pressure of ink at a nozzle 8 is determined by the difference in vertical height between the nozzle 8 and the upper end of a vertical groove 14, while said pressure has no relation to the level of ink surface in an ink storing section 10, so that said pressure is always kept constant regardless of the consumption of ink. Consequently, stable delivery of ink from the nozzle 8 can be achieved. And even when air flows from the nozzle 8 into a head and bubbles are produced, the bubbles go through an ink passage 9 into the ink storing section 10, whereby delivery of ink from the nozzle 8 is not disturbed. Further, even when the ink in the ink storing section 10 is forced out due to the expansion of the air therein caused by the temperature rise therein, said ink having been forced out is absorbed into an ink holding body 11. As a result, unexpected delivery of ink from the nozzle 8 can be avoided.

Abstract: PURPOSE:To prevent the generation of course stripes and improve the quality of woven fabric by placing a yarn-pushing reed opposite to a yarn-holding member fixed to the outside of a selvage at the weft-insertion side of a frame and pushing an end of the weft into a weft end channel immediately after the weft insertion. CONSTITUTION:An inserted weft 5 is beaten to a cloth fell 2 by beating motion and, simultaneous to or slightly before the beating motion, the yarn end 6 is pushed into a weft end channel 27 of a yarn-holding member 15 with a yarn- pushing reed 16 and bent in a zigzag state. the excess length necessary for the bending is tucked in from the cloth fell 2 to apply a tension to the weft 5 from the side opposite to the weft-insertion side. The zigzag state of the weft end 6 and the tension applied to the weft 5 are maintained after the return of said reed 16. The weft is pushed with the next yarn end 6 pushed in by the next beating motion, shifted toward the side opposite to the reed and cut with a selvage cutter 14 between the yarn end and the selvage 3. the cut yarn end 6 is further pushed in with the successively introduced other yarn ends and pushed out from the opening at the side opposite to the reed.

Filed: 1992-05-06
Abstract: PURPOSE:To facilitate the formation of a second joint by forming a joint made of soft plastics including a cross section-projected foaming substance and installing an adhesive layer to the lower part of the joint tape. CONSTITUTION:A cross section-projected expanded polyethylene joint tape 2 is formed. An adhesive layer 3 comprising an adhesive a parting paper is pasted to the lower part of the joint tape 2. A curing sheet 1 comprising a polyethylene film or the like is pasted to the upper part of the joint tape 2. The sheet 1 is designed to be as wide as the joint tape 2.

Filed: 1983-08-30
Abstract: PURPOSE:To lower the rate of exclusive occupancy of a multi-bus line when reproducing picture data by a printer through the bus line by storing the picture data from the bus line in a memory and thereby decoding by an RP adapter. CONSTITUTION:A main CPU4, a memory 5, a disk controller 6, an RP adapter 3 and a circuit controlling circuit 9 are connected to multi-data bus line 1-11 of a picture processing system.

Abstract: PURPOSE:To make it possible to continue the drive of a motor without stopping lines, by controlling the switchover from a feedback control to a V/F control, and viceversa based on the output of a part for sensing drive states. CONSTITUTION:A part 33 for sensing drive states monitors the drive states of a device 4 for controlling an induction motor. The part 33 judges the switchover from a computation part 9 for a feedback control to a computation part 8 for a V/F control, and viceversa based on the signals relative to the region of an output frequency and relative to the abnormality of a feedback control signal, etc. Thereby, the part 33 outputs a switchover command signal to a switchover control means 102. The switchover control means 102 can switch over drive modes by the signals from the part 33 for sensing drive states. Thus, the drive modes can be so switched over automatically according to the drive states, that the drive can be continued stably. Still, in order to set data so that the output of an electric power converter comes continuous when switching over, the signal of the computation part 8 for a V/F control is exchanged with the signal of the computation part 9 for a feedback control via the switchover control means 102.

Title: Sector opening/closing device
Inventor: OISHI SEIICHI
IPC: G03B9/10
Filed: 1999-06-07
Abstract: PROBLEM TO BE SOLVED: To obtain a good-quality image by making the speed at the time of starting operation of a sector opening/closing device high. SOLUTION: An acceleration lever 13 is coaxially provided on an opening/ closing lever 5 opening/closing sectors 7 and 8. By previously rotating a rotor before closing the sectors 7 and 8, the sectors are opened by little (to a line (a)) so as to charge a spring 14 provided in the lever 13 with energy. When the sectors 7 and 8 are closed, the rotor 1 is rotated from the line (a) to a line (c). At such a time, the lever 5 receives force obtained by adding energizing force by the spring 14 to driving force by the rotor 1. Since the rocking angle of the lever 13 is regulated, the energizing force acts only at the beginning. After the lever 5 is accelerated, a driving pin 5a is separated from an abutting part 13a, so that closing motion is performed only by the driving force of the rotor 1.
