Filed: 1985-01-17
Abstract: PURPOSE:To obtain good printing quality by smoothing speed change during printing, by performing the next acceleration after the elapse of the time corresponding to the same current supply time as that during printing and a current non-supply time in such a state that no current is supplied to a printing head. CONSTITUTION:After the phase of a pulse motor 24 is changed over even during acceleration, a counter circuit B10 performs counting operation and a reset signal C14 is issued from a central control circuit 1 immediately after the output signal 11 of the counter circuit B10 came to an H-level and, this time, a counter circuit C12 starts counting operation.

Title: Magnetic memory processing apparatus
Inventor: WATANABE YASUHISA
IPC: G11B20/12
Filed: 1978-01-23
Abstract: PURPOSE: To make processing in such a manner that when the end mark is detected it becomes a record non-detection error at the time when a magnetic head detects the next record by providing the end point mark to the record.  
     CONSTITUTION: When there is a magnetic head between the start point mark of the previous record, the rocord processing display signal is inputted from terminal 8 and the end point mark is detected before the start point mark of the record is detected. When it is detected that the reading of the start point mark has been skipped, the output of an AND circuit 32 is made "1" by the outputs of a record end point mark detecting circuit 2, record processing display signal 801, inverter circuit 31, whereby an error processing circuit 5 is started as a record non-detection error. At the same time the output 331 of an inverter circuit 33 is made "0" to stop operation of a data read-in circuit 4 so that even if the start point mark of the record to be read in subsequently is detected by mistake, that data will not be judged as the data of the intended record.

IPC: B23P19/04
Filed: 1996-01-18
Abstract: PROBLEM TO BE SOLVED: To automatically disassemble a die assembly for an extruder by providing an extruding cylinder pressing the die of the die assembly placed on a die assembly placing part of a disassembly device table provided with a U shaped gate and a holding cylinder in the position opposite to the extruding cylinder. SOLUTION: The die assembly after usage is transferred between the U shaped gate 2 and the extruding cylinder 3, and thrust onto the front surface of the die of the die assembly with the holding cylinder 4 advanced. The die is held with the holding cylinder 4 and the extruding cylinder 3, and pushed out the holder of the die assembly. As the diameter of the holder is larger than the gap of the U shaped gate, when the die 12 is pressed with the extruding cylinder 3, the holder is subjected not to pass through the U shaped gate 2, and then only the die is pushed out. The die is grasped with the die clamp of a picking device, pressing the die by the extruding cylinder 3 and the holding cylinder 4 is released to take out the die. By this way, the die assembly is automatically disassembled.

Abstract: PURPOSE:To reduce the amount of heat permeation and thus enable to lighten and form compactly the structure by adopting a supporting structure of the combination of a sliding structure with a pin structure. CONSTITUTION:A bobbin 2 around which a superconductive coil 1 is wound is fixed to a pipe 6 by the supporting structure 7, and further supported by an inner bath 4 through the supporting structure consisting of the pipe 6 and a supporting part 5.

Abstract: PURPOSE:To contrive not to be misconceived that even though a beam reflected by a disc is transmitted a half mirror and reaches a submount, a tracking error has been generated by a method wherein a laser chip is contrived so as to be mounted on the submount slanting its exit end face to oscillate laser light at a prescribed angel with the front end face of the submount. CONSTITUTION:A semiconductor laser is constituted in a structure, wherein a front end face 21 of a submount 20 is formed at a prescribed angle with an exit end face 11 of a laser chip 10 in such a way that the front end face 21 of the submount 20, whereon the laser chip 10 is mounted, and laser light to be oscillated from the laser chip 10 do not intersect orthogonally each other. Accordingly, even though a beam, which is reflected by the surface of a disc and is transmitted a half mirror, is irradiated on the front end face 21 of the submount, this beam is never reflected again in the direction of the disc. Thereby, an erroneous operation to be judged that a tracking error has been generated by the beam reflected by the front end face 21 of the submount 20 is never generated.

The means 8 designates an address decided by a remote control data or a key data in the storage means 6 and writes the said data to a storage part in the said address. Then the data read from the said address is compared with the data transmitted to the storage means 6 by the means 8 are compared by the discriminating means 5 and when they are coincident, the means 5 displays it to the element 1 that the storage processing is finished correctly, and the element 1 displays a data before the display is erased. When dissident, the same data is written and when the write operation is executed for a prescribed number of times or over, it is displayed that the storage processing is not correct. In case of the erasure processing, the procedure is similar as above.
