Title: Vane pump
Inventor: TSUCHIYA KEIJI
IPC: F04C2/344
Filed: 1982-04-23
Abstract: PURPOSE:To suppress the delivery pressure pulse by lagging the delivery opening position of the delivery stroke due to the cam curve by proper angle while pre- cmpressing the operation chamber prior to opening toward the delivery port. CONSTITUTION:When brought to section (b) of the cam curve due to the rotation of a cylindrical rotor 1, it will perform the inner compression because it is not opened toward the delivery port 8. Consequently the pressure in said operation chamber will increase and when the operation chamber in conducted with the delivery port 8, the pressure in the operation chamber can be brought higher than the oil pressure in the delivery port 8 continuously. As a result, the high pressure oil will not counterflow from the delivery port 8 side thus to suppress the delivery pulse caused by the counterflow of the high pressure oil.

Title: Control device of motor for deep sea use
Inventor: KATSURAGI YOSHIO
IPC: H02P1/26
Filed: 1987-03-23
Abstract: PURPOSE:To reduce resistant torque at the time of starting, by supplying low current to the primary winding of a motor to warm the oil. CONSTITUTION:When a stop signal is outputted, a timer 15 clocks the stop time of a motor and outputs. On the outer hand, when a ship is under water, the pressure of sea water is detected with a pressure detector 14. In case the diving depth is D, the time from stopping the motor to lowering the oil temperature to K is T, so that the pressure of sea water is detected when the ship submerges at the depth of D and at this pressure value an arithmetic unit 16 works out the time T and outputs the signal. Receiving this signal when the stop time clocked by the timer 15 becomes equal to the time T, a signal is outputted from a comparison circuit 17 and a signal discrimination circuit 18 outputs a warming mode signal corresponding to the pressure of sea water detected by the pressure detector 14. A power control circuit 19 outputs an ignition signal to a transistor 23 only during the period corresponding to the size of this signal. As a result, the voltage corresponding to the pressure of sea water lower than the rated voltage heats the primary winding 11 and warms the oil to keep the temperature.

Title: Nb series superconducting tunnel junction element
Inventor: TAKAMI TETSUYA
IPC: H01L39/22
Filed: 1985-04-01
Abstract: PURPOSE:To alleviate the increase in capacity between a wiring layer and a first electrode and to make an insulating layer thin, by forming an Nb anode oxide film as an insulating layer, and forming an insulating film, whose permittivity is lower than that of the Nb anode film, on said film. CONSTITUTION:A tunnel barrier 3 and a second electrode 4 are formed in an island shape on a first electrode 2. Thereafter, an Nb anode oxide film 5 is grown to a thickness of, e.g., about 300Angstrom  by an anode oxidation method. At this time, the anode oxide film 5 is formed on the upper part of the first electrode 2, the side surface part of the tunnel barrier 3 and the side surface part of the second electrode 4. Then an insulating film, e.g., an SiO layer 7, whose permittivity is lower than that of the anode oxide film 5, is deposited to a thickness of about 1,000Angstrom  by resistance heating. Thereafter, a wiring layer 6 is formed. In this constitution, since the anode oxide film 5 is as thin as about 300Angstrom , the undercutting at the time of anode oxidation is small and its junction having a minute area can be found. The thickness of SiO layer 7 is about 1,000Angstrom  and thin. Since the anode oxide film 5 is used together, the insulation property of the insulating layer formed by both the layer 7 and the film 5 is excellent.

IPC: G06F3/05
Filed: 1988-03-25
Abstract: PURPOSE:To reproduce the timing of the change in a AC signal correctly, by detecting the timing of the change in AC signal based on whether the signal in the vicinity of zero continues for the predetermined specified time or not, forming a step shaped signal from the changing state, and plotting the signal. CONSTITUTION:At first, whether a read AC signal 1 is in the vicinity of zero or not is checked based on whether the signal is within + or -delta or not by using the value delta specified beforehand. When the signal is within + or -delta, whether the state within a value + or -delta is continued for a specified time or more is checked. The facts that whether the read data are in the vicinity of zero by change and whether the data are in the vicinity of zero without the AC signal are judged. When the state within + or -delta continues for the specified time or more, the value of the step shaped signal is made to be zero. When this condition is not satisfied, the value of the step shaped signal is made to be 1. The step shaped signal is sent to a plotting part 5 and plotted. Thus, the timing of the change in AC signal 1 is reproduced correctly.

Title: Center hub for information recording disk
Inventor: KIMURA YUKIYASU
IPC: G11B23/00
Filed: 1985-04-02
Abstract: PURPOSE:To facilitate work at fitting and assembling and to improve reliability with respect to fixing force by installing a collar capable of partially elastic deformation at least either one of a pair of vertical metallic hub members and fixing a disk with the aid of the restoring force of the collar. CONSTITUTION:It is assumed that the collars 2a and 3a can be deformed partially and elastically. When a screw 4 tightens the metallic hub members 2 and 3 in one body, a clearance 5 disappears, and the collars 2a and 3a develop elastic deformation. Due to the elastic restoring force arising at this time, the collars 2a and 2a hold and fix the disk 1 at both sides. The holding force at this time can be controlled by changing previously length and thickness in the parabolic direction of the collars and the quantity of the clearance 5. Thus the ring-like disk can be securely fixed without giving any damages such as deformation and cracks, and the hub and the disk will not dislocate in a long time.
