Title: Vane back-pressure imparting device for sliding vane-type compressor
Inventor: HASEGAKI TAKAHIRO
IPC: F04C18/344
Filed: 1987-02-10
Abstract: PURPOSE:To prevent the malfunctioning phenomenon of a vane by providing, at a gas-supply passage connecting a vane back-pressure chamber to the high pressure side, a passage-open/close-means and a gas-supply passage with a non-return valve connecting the back-pressure chamber to the intermediate pressure side. CONSTITUTION:In case of a compressor being started when there is no pressure difference between the high pressure side and low pressure side, a valve-body 37 operates due to the pressure-lowering of a vane back-pressure chamber, and the 2nd gas-supply passages 33, 34 are connected, and high pressure gas is supplied to the vane back-pressure chamber from the 1st gas-supply passage 27. When the pressure of a high-pressure chamber 14 rises, the valve-body 37 is closed due to pressure change inside the 2nd gas-supply passages 34, 33 and at the same time, a valve-body 30 is closed, too, and a passage 31 and the 1st gas-supply passage 27 are cut-off. Accordingly, pressure-lowering inside the vane back-pressure chamber is prevented, and the malfunctioning phenomenon of a vane is prevented.

Title: Encoding circuit and signal processor
Inventor: EZAKI TADASHI
IPC: H04N19/70
Filed: 1999-02-05
Abstract: PROBLEM TO BE SOLVED: To provide an encoding circuit that is effective against falsification. SOLUTION: A digital watermark imbed means 1 imbeds a digital watermark including copy control information(CC information) to original contents S0. An orthogonal transformation circuit 32, a quantization circuit 36, an encoding circuit 38 and a digital watermark decoder 40 are integrated in order to make impossible an external access to a digital watermark decode and a signal compression circuit block 3 acting as the encoding circuit. The orthogonal transformation circuit 32 applies orthogonal transformation to digital watermark imbed information S1 into a sub-band signal, and the digital watermark decoder 40 detects the CC information S40.  The quantization circuit 36 quantizes an orthogonal transformation processing signal S32 only when a copy of the CC information is permitted and the coding circuit 38 encodes a quantized signal S36 only when the copy of the CC information is permitted. The quantization circuit 36 or the encoding circuit 38 outputs invalid data when the copy of the CC information is inhibited so as to output a meaningless copy on the occurrence of falsification.

Title: Reception circuit
Inventor: OOKUBO TSUNEO
IPC: H03G3/30
Filed: 1981-02-27
Abstract: PURPOSE:To reduce a signal distortion at a large input signal reception and to increase the S/N, by performing gain control of an intermediate frequency amplifying circuit before the gain control of an AM frequency converting circuit. CONSTITUTION:At the reception of a small signal, a detected DC voltage obtained at AM detection transistors (TRs) 401 and 402 is small, but at the reception of a large signel, the voltage is greater, a TR411 turns from on to off, and a TR412 goes to the reverse state. Thus, the current of TRs 301 and 302 of an intermediate frequency amplification circuit 3 is reduced, the gain is also reduced and a signal at the collector of TRs 321 and 322 is suppressed to an amplitude which is not so much greater. When an input signal is further increased, a  TR306 completely turns off and the gain of the intermediate frequency amplifying circuit 3 and a frequency converting circuit 1 is suppressed.

Title: Magnetic disk device
Inventor: TAKIZAWA TOSHIMITSU
IPC: G11B19/20
Filed: 1988-02-10
Abstract: PURPOSE:To achieve a prescribed revolving speed of a magnetic disk in a short time with simple constituiton and to attain a large capacity by enlarging torque until the magnetic disk reaches the prescribed revolving speed and keeping constant torque after reaching the prescribed revolving speed. CONSTITUTION:When the title device is started up, a relay 6 is changed over to a terminal 4 side by a control circuit 7. Consequently, a main coil 9 is inserted with a starting coil 10 to enlarge the torque. Afterward, when the circuit 7 detects that a spindle motor 1 reaches its steady revolving speed, the relay 6 is changed over to a terminal 2 side. In this case, since a driving electric current from a driving circuit 8 into the motor 1 flows individual main coils 9 only, a counter-electromotive force is small, and hence a current fluctuation to be supplied from a constant-voltage power source is little. Therefore, the prescribed revolving speed is achieved in a short time and then maintained constantly, thus ensuring a large capacitorization.

Title: Thermal conductivity meter
Inventor: KOKUBO ATSUO

Filed: 1978-03-17
Abstract: PURPOSE: To make it possible to meter the thermal conductivity in a pormpt manner by providing a pair of electronic heat pumps, which are composed of Pelche elements holding a sample  plate inbetween, and a pair of heat reservoirs at a preset temperature such that they are incontact  with the pumps so that the temperatures at the both sides of the plate may be metered with the  use of the temperature metering element.   
     CONSTITUTION: Eelectronic heat pimps 2 and 2' are mounted on the both sides of a sample  plate 1 such that one is for heat liberation whereas the other for heat absorption. A pair of heat  reservoirs 3 and 3' are provided such that they are in contact with the pumps 2 and 2' and that  they are held at a preset temperature. By feeding a preset current to the pumps 2 and 2', heat  flows out of the one pump 2 and is absorbed through the plate 1 by the other pump 2'. As a  result, the whole system promptly assumes a steady state, and the temperature difference ΔT between the bith sides of the plate 1 at that time is metered by means of elements 4 and 4' to determine the calory Q from the pump current and the plate surface temperatures. The thermal conductivity can be easily deduced from Equation -Q/X = λΔT/x (wherein S stands for the surface  area whereas x stands for the thickness.). Thus, the thermal conductivity can be promptly  metered accurately with the use of a small quantity of the sample.

The mean value calculating circuit 21 uses the signal of the circuit 20 as an input to obtain the mean value AVE1 of the video signal as well as the mean value AVE2 of the video signal less than the threshold value. The MAX/MIN value detecting circuit 22 detects both the MIN value VMIN and the MAX value VMAX of the video signal, and the ALU circuit 23 performs these arithmetic operations to obtain the threshold values VTH1 and VTH2. the voltage comparator 24 compares the quantized video signal quantized in the above-mentioned processing region and the value VTH2 obtained at the ALU circuit 23. Thus the target signal can be extracted.
