Title: Cushion pin of cushion draw die
Inventor: YOKOTA FUMIKI
IPC: B21D45/04
Filed: 1980-06-24
Abstract: PURPOSE: To eliminate noise and vibrations efficiently by constituting cushion pin bodies extensibly and energizing the same in an extension direction by spring means having spring force smaller than the force that they receive from a cushion pad.  
     CONSTITUTION: After a work 20 is put on blank holders 18 having drawing beads, a male die 15 is lowered based on the operation of a press slide. As the male die 15 descends, cushion pins 1 of spring force smaller than that of a cushion pad 19 provide cushioning effect first. Thence, when the pad 1 shrinks to a certain degree  pusher heads 4 cylinder tubes 2 abut, thereby directly coupling the blank holders 18  and the pad 19. The male die 15 descends together with the blank holders 18 by  overcoming the force of the pad 19 and formes the work 20 cooperatively with a  female die 16.

CONSTITUTION:Based on tape length information of a cassette tape (CT) 56 and TOC information of the CD 31, reproducing order of the CD 31 is decided without reaching the finishing end of the A-side in the midst of recording the CT 56 by calculating processing in a CT control circuit 61, and is stored in a memory of a CD control circuit 40. According to this reproducing order, the MD 13 is recorded out of the CT 56, and upon completion of the recording, based on the reproducing order information of the CD 31 recorded in the CD control circuit 40, an MD control circuit 19 is operated to record TOC of the MD 13 so as to identify the track number of the MD 13 with that of the CD 31. By this method, even when the CD and the MD are simultaneously recorded, the recording is performed without breaking a track of the CT in the midst of the recording, and also the track numbers of the CD and the MD can be identified with each other.

Filed: 1989-04-05
Abstract: PURPOSE: To monitor the charging state of a storage battery by measuring voltage of a storage battery or voltage to be impressed on the battery by a very different operating state during a measuring phase, storing voltage and subsequently evaluating voltage from a charging current intensity point of view. CONSTITUTION: Voltage just before a rectangular charging current pulse is terminated is measured and this voltage is stored. Next, a storage battery is charged by current intensity 2 Ic for a preliminarily selected period T2 . After current to the storage battery is interrupted for a period T3 , the storage battery is made into a load state by load current of a size - Ic for a period T4 . Subsequently, current to the storage battery is interrupted for a period T5 and each voltage is measured after about 0.2 seconds from the starting of each operation and at a termination point of time. Next, a charging operation is resumed by the next charging current pulse, each internal resistance of the storage battery is determined from the measured voltage value and current intensity at the time and internal resistances determined in a series of measuring phases are correlated one another.  Thus, data of the charging state, etc., of the storage battery can be obtained during the charging operation.

IPC: B41J2/485
Filed: 1985-04-20
Abstract: PURPOSE:To enable both longitudinal and lateral characters to be easily printed, using a driving mechanism of almost the same type as a conventional one, by arranging plural dot recording heads obliquely against the movement direction of a head device a printing paper. CONSTITUTION:The arrangement direction of heads 1a-1g is set at almost 45 deg. degrees to an arrow A direction. When printing longitudinal characters 3, a head device 1 is allowed to move in an arrow A direction. When printing lateral characters 4, a printing paper 2 is allowed to move in an arrow C direction. This movement in either A direction or C direction is performed at a pitch of every single dot. When printing of either longitudinal 3 or lateral 4 characters, the same character information is read from a common memory and this character information thus read is delayed by individually different time to heads 1a-1g and added to each head 1a-1g. Consequently, it is possible to print longitudinal and lateral characters easily and selectively using a driving mechanism of almost the same type as a conventional one.

Title: Method and device for phase controlling of welding machine
Inventor: YOSHIMURA KATSUO
IPC: B23K9/06
Filed: 1981-06-04
Abstract: PURPOSE:To make the controlling of the secondary voltage waveform effective for welding in a short time electricity conduction possible by applying a reverse voltage to one of control rectifying elements coupled respectively to the voltage changing taps on the primary side of a welding transformer to extinguish its arc and commutating the same to the other. CONSTITUTION:If in an electric power sourceI-II (a) firing signal is applied  to a thyristor (THY)A from a firing circuit, the secondary voltage waveform 6  8 appears from a welding transformer 12. Here, a THYB is fired by the firing  signal of the firing circuit. Then, the primary voltage of the transformer is  higher with the other tap T1 than one tap T2 by the effect of the transformer  12. Since the anode voltage to be applied upon the cathode of the THYA is the differential voltage of the taps T1 and T2 as a negative voltage, the THYA is  extinguished and the THYB fires. The commutation of the THYB continues to  fire until the current conduction period determined by the reactance of the welding machine. In the period (a), the voltage waveform 6 8 9 appears accordingly. The same procedure is held in the period (b) where the power source inverts.

Abstract: PURPOSE:To ensure the proper and unmanned removal of bead chips projected from the end of a seam welded pipe of predetermined sizes by automatically clipping, bending, fracturing and sliding said chips down on a chute at the side of a roller, with a lever provided in parallel with the roller, during the transfer of the pipe on the roller. CONSTITUTION:A detecting mechanism detects a seam welded pipe 1 of predetermined sizes moving on a roller 2 with a drive mechanism, thereby enabling the clipping face 6a of a lever 6 and the clipping face 7a of another lever 7 to catch an internal surface bead chip 4 projected from the trailing end of the seam welded pipe 1. At this time, the bead chip 4 is bent and fractured by a cutting knife 7b at the lateral angular part of the clipping face 6a. A process of clipping and fracturing takes place one after another in a plurality of bead chip removal devices 5 and the bead chip 4 comes out of the seam welded pipe 1, finally moving to the side of the pipe 1. Then, a lever 6b turns and the bead chip 4 moves to a chute 8, finally sliding down. In this way, the bead chip 4 is properly removed from the inside of the seam welded pipe 1 and manpower can be saved.
