Title: Optical pickup device
Inventor: MASUNAGA YOSHIFUMI
IPC: G11B7/09
Filed: 1989-06-09
Abstract: PURPOSE:To reduce the number of components by integrally molding a suspension composed of a fitting base part fitted to an actuator base, a pair of suspension parts having two bar shape supporting bodies and a holder fitting part with a synthetic resin. CONSTITUTION:Since a suspension 15 composed of the fitting base part to an actuator base 16, a pair of suspension parts 15c and a holder fitting part 15d is integrally molded with the synthetic resin, the dispersion of products due to the combination of plural parts is eliminated, and the suspension 15 having a stable performance can be obtained. Thus, the management of the dimensional accuracy of each component does not need to be executed, and by the integrated molding of the synthetic resin, the number of components can be reduced, and manufacture can be inexpensively carried out. Further, since the suspension parts 15c are formed as the bar shape supporting bodies with uniform sections, respectively, a creep deformation due to a stress concentration to a specific part can be prevented, and respective characteristics as a pickup device can be maintained.

Title: Superconduction logic circuit element
Inventor: HATANO YUJI
IPC: H03K3/38
Filed: 1989-06-09
Abstract: PURPOSE:To obtain a logic circuit with less occupancy area and power consumption by adopting a constitution such that an output is obtained from a load resistor when an input is given to both of Josephson elements among Josephson elements. CONSTITUTION:The element is constituted of output stage gates 401-403 and input stage gates 411-413 being a Josephson quantization interference type device. A voltage is applied to an AC power supply bus 219 before a control line input is generated to make a gate current flow to gates 401-403 and 411-413. In this case, when an input is given to any of control lines 451-453, the input stage gate receiving the input is switched from the superconduction state into the voltage state and the gate current flowing to the input stage gate transfers to the output stage gate. Then when an input to any of the control lines 451-453 occurs, the output stage gate receiving the input is switched from the superconducting state into the voltage state and an output current is made flow to a load resistor provided in parallel on the switched output stage gate.

Title: Pickup device
Inventor: HATSUTORI OSAMU
IPC: G11B9/06
Filed: 1981-09-18
Abstract: PURPOSE:To eliminate jitter without changing the state of contact of a spot scanning stylus, by making the driving force generated from a magnet and a driving coil parallel with a disk surface, and making the fulcrum of a supporter and the center line of the magnet coincident with the direction of the driving force. CONSTITUTION:A straight line connecting the fulcrum P and the center Q of a magnet 6 is set in parallel to a disk surface 12, and the direction of the driving force generated from a driving coil 10 and the magnet 6 is made coincide with said straight line. As a result, only the force that is parallel to the surface 12 is applied to a scanning stylus 3 to avoid a change of the state of contact. However, an attachment error of a supporter produces the rotary movement in the direction vertical to the surface 12 with the fulcrum P of a cantilever 1 set as an axis. To get rid of the effect of the rotary movement, a bias current is supplied to a driving coil 10. Thus the force F' is generated to attract a permanent magnet 6, and the force F' is also made parallel to the surface 12. A straight line PQ is coincident with a straight line OO' by the function of F'' of the component forces F'' and F'''. As a result, an attachment error is compensated.

Filed: 1980-10-21
Abstract: PURPOSE:To prevent explosion of dilution-purpose H2 in the event of gas leakage by utilizing the gas adding monosilane 1% or more to phosphate or diborane. CONSTITUTION:Monosilane gas easily catches fire naturally when even a very slight amount of the gas makes contact with the air and the monosilane of 1% which is diluted with Ar causes a spark in the dark place. Therefore, when PH3, B2H6 of H base including monosilane may be leaked out, the monosilane instantaneously facilitates burning of H2 as an ignition source. The H2 burns at a leakage port, but causes no explosion. According to the above constitution, it is desirable that an Si film is growed on a substrate through glow discharge by utilizing monosilane, phosphine and diborane diluted with H2 respectively.
