Title: Method for reproducing disk player
Inventor: NEGISHI TADASHI
IPC: G11B7/00
Filed: 1993-09-30
Abstract: PURPOSE:To prevent the repeated missing sound caused by the damage of the disk by searching the damaged position where the missing of sound occurs at the time of reproduction and changing the searching position when the number of searchings to the same position reaches to the prescribed number. CONSTITUTION:A signal read out from an optical pickup PU 1 is demodulated by a digital signal processing circuit 4 and outputted from an amplifier 6 through a D/A converter 5. When something causes a missing of sound during the reproduction, the absolute time stored in the memory circuit in a system control circuit 7 just before the PU 1 is moved is taken as B and the absolute time of the present location is taken as A and the searching of B is performed when A< B or A-B> the prescribed time. When the reproduction is not available at the location of B, the number of searching is counted by a counter in the circuit 7. When it reaches the prescribed number, the counter is set to the position adding the prescribed time to the B.

Title: Pressure limiter for syringe pump
Inventor: YAMAGATA HIDETO
IPC: A61M5/00
Filed: 1993-09-07
Abstract: PURPOSE:To automatically close a liquid chemical flow passage so as to protect a patient when the liquid pressure of transfusion rises to a specified pressure or above. CONSTITUTION:A valve 25 having a valve disk 25a and a valve seat 25b is disposed in mid-way of the liquid chemical flow passage from an inlet pipe 22 to an outlet pipe 23 of the pressure limiter 4. This valve 25 is operated to be closed by a diaphragm 26 which receives the liquid pressure on the upstream side thereof. This diaphragm 26 is lifted by overcoming the force of a back spring 29 to press the valve disk 25a to the valve seat 25b and to close the flow passage 24 when the downstream side is clogged during transfusion and the liquid pressure rises to the specified pressure or above. As a result, the supply of the liquid chemical to the downstream side is shut off and the danger that the liquid pressure higher than the specified pressure acts on the patient is prevented. The liquid pressure on the upstream side increases more when the flow passage 24 is closed. This liquid pressure acts to more close the valve 25.

Title: Semiconductor device
Inventor: KATO KOICHI
IPC: H01L29/786
Filed: 1984-11-22
Abstract: PURPOSE:To reduce an intrusion to a gate oxide film of carrier pairs generated through impact ionization by forming a channel region to a curved surface shape along the gate oxide film. CONSTITUTION:A circular opening section is formed to an Si layer 12 shaped onto an insulating substrate 11. The surface of the Si layer 12 is oxidized to form a gate oxide film 14 on the side wall of the opening section, and a poly Si film 15 for a gate electrode is buried and shaped into the opening section. Impurity ions are implanted to form source-drain regions 16a, 16b. An inter-layer insulating film 18 is shaped onto the whole surface, contact holes 19 for electrodes are bored to the film 18, and Al wiring layers 20 are formed. Consequently, electrons from the source 16a flow while drawing arcs along the gate oxide film 14, but electrons separate from the film 14 and flow in bulk Si because they are accelerated in the vicinity of the drain 16b. Accordingly, electrons are difficult to intrude to the gate oxide film.

Title: Process identifying device
Inventor: AZEGAMI TADASHI
IPC: G05B13/02
Filed: 1990-09-17
Abstract: PURPOSE:To save the time and the electric power for identification of a process by putting a process identifying process into the process starting process. CONSTITUTION:A control output changing means 3 receives an identifying instruction and orders a PID control arithmetic means 1 to output the control output MV to a process 2. Then a changing rate detection means 4 holds the changing rate DPV set when the process value PV has a satisfactory rise as a reference changing rate RefDVP. The means 3 reduces temporarily the output MV. A changing rate comparison means 5 compares both rates DPV and RefDPV with each other. A time measuring means 6 measures the time suring which the modulation of the rate DPV is detected by the means 5 as an equivalent dead time TL and sends this time to an arithmetic parameter setting means 7. The means 7 carries out each arithmetic operation based on the time TL and the rate RefDPV and set an arithmetic constant to the means 1. Thereafter the output of the means 1 is added to the process 2 and the value PV follows the target set value SP.

Abstract: PURPOSE:To enable high-precise control of the position of a rotary shaft, by a method wherein a control magnetic field is exerted on a magnetic bearing in relation to the displacement of the rotary shaft, detected by means of a displacement detector to correct displacement. CONSTITUTION:An NC device 30 controls running of a motor to rotate a workpiece at the arbitrary number of revolutions.

Thus, control is effected so that the gap (e) between the disc 14 and each of the cores 17a-17d is uniformized. This constitution enables highprecise control of a position in relation with the rotation center of a rotary shaft.
