Title: Magnetic tape transcriber
Inventor: WATANABE HIROSHI
IPC: G11B5/86
Filed: 1978-08-25
Abstract: PURPOSE: To attain efficient transcript with the mounting of a transcribed slave tape simplified by providing a detachable traveling piece to the outer circumference of a take-up reel and by making an insertion part larger by projecting the traveling piece from the reel in tape mounting.  
     CONSTITUTION: Master tape reel 2 is mounted and master tape 1 is pulled out. As soon as mounting-demounting switch 15 is depressed and locked, solenoid 13 operates to separate traveling piece 9 from take-up reel 5 and project it. After the tip of tape 1 is fixed to fixture pedestal 10 by a spring, switch 15 is unlocked by depressing again, so that traveling piece 9 will return into the reel and fixed. Next, mounting cassette 8 with incorporated slave tape 3 turns ON detection switch 16 and solenoid 13 is driven to project traveling piece 9. As a result, the tip of tape 3 can be fixed to the fixture pedestal easily and efficient transcription can be carried out.

Title: Recording and reproducing device
Inventor: TAKEKADO SHIGERU
IPC: H02K33/18
Filed: 1988-04-28
Abstract: PURPOSE:To attain rapid access appropriate for a miniaturized device by means of a simple constitution and to obtain a recording and reproducing device appropriate for high density recording by inserting and fixing a driving coil into/on a coil supporting frame fixed on an actuator without using a winding frame. CONSTITUTION:Yorks 10a-10c and permanent magnets 11a, 11b constituting a magnetic circuit constitute a driving motor together with a driving coil 9 and the driving coil 9 is inserted and fixed into/on the coil supporting frame 12. In said constitution, a position error signal is obtained by a transducer 5 and fed back to the driving motor to move and position an actuator 7 to/on an optional position. Since the length of a magnetic gap is determined by the thickness of the coil and clearance, the device can be constituted of minimum units. Consequently, inertia at the time of accessing can be reduced, the resistance and inductance of the coil can be also reduced and rapid access can be attained by means of a miniaturized device.

Title: Pattern recognition for wire bonder
Inventor: YAMAZAKI NOBUHITO
IPC: G06T1/00
Filed: 1982-06-17
Abstract: PURPOSE:To improve yield, by a method wherein a sample pattern is detected by employing a sample reference pattern and a pattern formed by rotating the reference pattern by a predetermined angle. CONSTITUTION:When a reference pattern 1 is stored i a memory, patterns 2, 3 are stored which are formed by rotating the reference pattern 1 by + or -10 deg., which is twice as large as an undetectable range + or -5 deg.. In recognition of a sample pattern, if it is detected on the basis of the patterns 1-3, even the patterns 2, 3 can be detected within a range of + or -5 deg.; hence, the inclination of a pellet with respect to a lead frame can be detected over a range of + or -15 deg.. It is to be noted that the rotation of the reference pattern 1 is effective if it is not exceeding the angle twice as large as the undetectable range. This method makes it possible to widen the detectable range, so that the yield is improved.

The means 3 delivers a corresponding failure indication number E1 and the means 6 delivers a similar failure indication number Ea. Consequently, the failure indication number E1 indicative of failure of the temperature sensor S flickers on a failure indicating means 5 and the failure indication number Ea indicative of disconnection of the temperature sensor S flickers on an individual failure indicating means 7.

Title: Optical axis scanning mechanism
Inventor: OMATA SATOSHI
IPC: G02B26/10
Filed: 1989-04-26
Abstract: PURPOSE:To position the light with which an object is irradiated at a high speed with high accuracy by oscillating one reflecting mirror vertically and oscillating the other reflecting mirror horizontally so as to reflect the light by two pieces of the reflecting mirrors, thereby executing two-dimensional scanning. CONSTITUTION:The light 5 emitted from an exit port 6 on the right side of the rear surface of the reflecting mirror 3 is projected and reflected from the right side at the right end of a stay 2 to the reflecting mirror 7 and is then reflected right forward by the reflecting mirror 3 so as to irradiate the object with the reflected light. The vertical direction of this position is adjusted by oscillating the reflecting mirror 3 in an arrow gamma1 direction by an actuator 4 and the lateral direction is adjusted by oscillating the reflecting mirror 7 in an arrow gamma1 direction by an actuator 1b. The load when the reflecting mirror 7 is oscillated at this time is only the reflecting mirror 7. One piece of the short transmission shaft is necessitated in this way and since the power transmission system has high rigidity, the system does not vibrate. The exact positioning at the high speed is thus possible.

Title: Production of hot rolled steel plate excellent in fatigue characteristic
Inventor: ASO TOSHIMITSU
IPC: C22C38/12
Filed: 1990-04-20
Abstract: PURPOSE:To stably produce a hot rolled steel plate excellent in fatigue characteristics by subjecting a steel having a specific composition consisting of C, Si, Mn, Nb, Al, and Fe to hot finish rolling at specific temp., carrying out specific forced cooling and air cooling, and then coiling the resulting steel plate at specific temp. CONSTITUTION:A steel having a composition consisting of, by weight, 0.02-0.15% C, 0.02-0.40% Si, 0.2-1.5% Mn, 0.010-0.05% Nb, 0.01-0.10% Al, and the balance Fe with inevitable impurities is subjected to hot finish rolling at a temp. between Ar3 and (Ar3 + 80 deg.C). The resulting hot rolled plate is subjected, immediately after rolling, to cooling down to (Ar3 - 200 deg.C)-(Ar3 - 50 deg.C) at 20-200 deg.C/sec cooling rate. Owing to this rapid cooling, fine ferrite nuclei are formed in great numbers in the austenite grain boundaries. Then, this hot rolled plate is air- cooled and coiled at 550-750 deg.C. By this method, the hot rolled steel plate having fine crystalline grains and excellent in fatigue characteristics can be obtained.

Abstract: PURPOSE:To improve the disk exchanging speed and to ensure the assured actuation of an automatic disk changing device by providing a control means which transfers the 2nd disk to a reproduction mechanism while the 1st disk is kept waiting temporarily after the 1st disk is transferred to the reproduction mechanism and reproduced. CONSTITUTION:A disk 101 extracted out of a tray 100 is reproduced by a disk reproduction mechanism 580 via 1st and 2nd loading mechanisms 300 and 400. The 2nd disk is extracted out of the tray 100 and shifted to the mechanism 580 for reproduction via mechanisms 300 and 400 while the 1st disk with which the reproduction is through is kept waiting temporarily at a disk temporary waiting mechanism 600. In such a way, the disks 101 are successively stored again to the tray 100. A series of these actions are commaned from an operation part 900. As a result, the priority is given to the loading action to shorten the total time required for operation. In such a way, the disk changing speed is improved and the assured actuation of an automatic disk changing device with a simple constitution is attained.
