Title: Optical reproducing device
Inventor: ARATAKI YUUJI
IPC: G11B21/10
Filed: 1989-01-20
Abstract: PURPOSE:To evade the occurrence of malfunction by using a signal made by extracting a high band component of an acceleration detector as a gain control signal for a tracking servo. CONSTITUTION:An output of the acceleration detector 7 to be moved in synchronization with an optical pickup 1 is inputted to an integration circuit 8 and converted into a signal in proportion to the above speed and then inputted to a linear motor driving circuit 6 so as to perform a moving speed control on the pickup 1. The output of the detector 7 is extracted in its high band component only and inputted to a gain control circuit 10, and its decay amt. is diminished in response to an output increase of a waveform shaping circuit 9 while a signal level to be inputted to a phase correction driving circuit 4 is increased so as to enlarge a loop gain. By this method, the loop gain is raised only when disturbance is impressed so as to achieve an accurate operation, and when it is not impressed, malfunction due to a defect, etc., can be evaded because of the loop gain set to be small.

Title: Cassette carry-out device
Inventor: MIYAHARA AKIRA
IPC: G11B15/675
Filed: 1989-01-24
Abstract: PURPOSE:To improve the operability of a cassette carry-out device by using a means which detects the movement of a shutter caused by a prescribed operation and outputs a detection signal and another means which carries a cassette out of a cassette store part based on the signal received from the detecting means. CONSTITUTION:When a shutter 6 is pushed, the shutter 6 turns round a rotary shaft 23 and therefore a detecting parts 27 turns while drawing an arc-shaped locus 28. In this case, the parts 27 touches successively the mechanical switches 29a and 29b to turn them on. Then the detecting signal for the turn of the parts 27 is sent to a drive control circuit 32. Thus the circuit 32 drives a drive motor 20 of a carry-out mechanism, and a cassette 30 is taken out. In such a way, the coincidence is secured between an ejecting operation area and the carry-out port of the cassette 30. Thus it is possible to obtain a cassette carry- out device that can easily be operated even by a user who is unfamiliar with the VTR operation with the excellent operability and no misoperation.

IPC: G06Q50/00
Filed: 1985-01-29
Abstract: PURPOSE:To prevent the same data from being accidentally re-totalized by outputting article processing result data with the attachment of arrangement data and discriminating whether the data is correct or not on the basis of the regulating data. CONSTITUTION:When the processing data attached 1 with the arrangement data are outputted from segmenting machines 11a, 11b and coding devices 12a to 121, these data are stored in a RAM16 while they are checked by a CPU14 whether the arrangement information outputted together while these data are specified values or not. Thus it judges the data to be correct when the equation L+1=M holds by comparing a set value L stored in the RAM16 with the arrangement information M. This information M is stored as a new set value L in the RAM16. In such a manner the data are judged to be correct by the information M, the processing is continued so that the past data are read from a disk driving device 17 to make a totalization with new data.

Filed: 1983-01-28
Abstract: PURPOSE:To eliminate danger of an electric shock by using the detecting part of a leakage detector as a heat sensitive resistor element and insulating electrically the detecting part and a leaking body. CONSTITUTION:A series circuit of a resistor R1 and a heat sensitive resistor element Th1 and a series circuit of a resistor R2 and a heat sensitive resistor element Th2 are provided in parallel. Electricity is preliminarily conducted to the elements Th1, Th2 to increase beforehand the temp. of the elements. The element Th2 is provided in the position where a leaking body is easily detected, and the element Th1 is provided in the position where the element does not contact with the leaking body. The temp. of the element Th2 decreases by contact with the leaking body and the divided voltage of a voltage dividing point B changes. The voltages at the voltage dividing points A and B are compared with a voltage comparator C. When a difference arises in the voltages between the points A and B, a relay RY is operated by the output of the comparator C, by which leakage is detected. Since the leakage is detected by detecting the temp. of the leaking body, there is no danger for an electric shock.

Title: Method for growing crystal
Inventor: ISHIKAWA TAKEMASA
IPC: C30B19/08
Filed: 1985-01-29
Abstract: PURPOSE:To obtain a good-quality crystal without any cracks and deformation by forming a temp. distribution wherein cracks and deformation of a substrate are not generated in a vertical furnace in the growth of a crystal by a liq.-phase epitaxial method. CONSTITUTION:When a crystal is grown by a liq.-phase epitaxial method, the temp. in a vertical furnace from the lowermost part of a crucible to a height of 100mm immediately above the melt surface is kept substantially constant at 870+ or -0.5 deg.C, for example, and gradually lowered as the height is increased. A substrate is gradually lowered from the upper part until the one surface of the substrate comes into contact with the melt to grow a single crystal film. Accordingly, the temp. does not change until the substrate reaches the melt, no cracks are formed in the substrate, and hence a good-quality crystal without any cracks and deformation can be obtained.
