Title: Self-excited oscillator
Inventor: ABE KIMIHITO
IPC: H02M7/537
Filed: 1984-02-24
Abstract: PURPOSE:To stabilize a conducting period by flowing a reverse base current when a transistor is turned OFF. CONSTITUTION:A series circuit of a diode D3 and a resistor R3 is bridge between one end of a feedback winding NB in which a positive voltage is induced when a transistor Q is turned ON and the base of the transistor Q. When the transistor starts turning OFF and a flyback voltage is induced, a reverse base current is flowed through the emitter and base resistors of the transistor Q and the diode D3, and the transistor Q is completely turned OFF. When the transistor Q is turned ON, the forward base current flowed through a capacitor C1, a resistor R2 and a diode D1 from one end of the winding NB flows depending upon the capacitor C1 and the resistor R2.

Abstract: PURPOSE:To obtain the subject apparatus for pressurization treatment of a fluid having a compact volume as the whole apparatus and capable of improvement of productivity by communicating a pressure vessel to a converter through a communicating hole of a connected rod and making the constitution capable of pressurization treatment of the fluid by a piston in the above-mentioned converter. CONSTITUTION:A fluid as the object to be treated is supplied from a supply path 4b of a connected rid 4 into a pressure vessel 1 and a converter 18 and a piston in the converter 18 is then actuated to pressurize the fluid in the converter 18. As the converter 18 is communicated to the vessel 1, a fluid in the vessel 1 is pressurized at the same time as pressurization of the fluid in the converter 18. After completion of the above-mentioned pressurization treatment of the fluid, a gas is supplied from a gas-supply line at the end part opposite to the connected rid 4 of the vessel 1 in order to rapidly discharge 4c the fluid from the rid 4. Accordingly, the pressurization treatment of the fluid is carried out by actuation of a piston 17 in the converter 18 communicating to the vessel 1 and the post-treatment fluid is discharged 5 by the gas supplied 7 from the end part of the vessel 1. Discharge of the fluid can be carried out rapidly without requiring enlargement of the stroke of the piston therefor.

Filed: 1984-02-24
Abstract: PURPOSE:To perform sharp working at a high speed by oscillating laser light around the prescribed axis while adjusting the focus of the laser light at a material to be worked thereby scanning the laser light. CONSTITUTION:Laser light arrives at a laser head 112 via transmission bodies 132, 134. The laser light passes through a beam expanding means and lens and is reflected by mirrors so as to focus onto a fabric. Respective operation commands are emitted in this stage from a cutting control part 402 to an operation board 406 for driving the head and a servocontroller 408, by which a focus adjusting device 412 is driven. More specifically, the lens is moved in the optical a xis direction in accordance with the scanning of the 1st and 2nd mirror driving devices for the laser light, by which the optical distance between the lens and the fabric is controlled to a constant distance. The fabric is thus cut in the focused state.

Title: Semiconductor device
Inventor: KAWAMOTO HIROSHI
IPC: H01L23/02
Filed: 1979-03-23
Abstract: PURPOSE:To obtain a semiconductor device in which an erroneous operation of an active region due to alpha rays never occurs, by forming a film of non-thermoplastic fluororesin on the inner surface of a package cap. CONSTITUTION:A layer of fluororesin of approximately 100mum in thickness is formed on the inner surface of a cap 16. Since the range of alpha rays in a fluororesin layer in Teflon of fluororesin is approximately 90mum, alpha rays passing through the inner surface of the cap are shielded. Since a semiconductor chip has a thickness of not less than around 150mum, alpha rays from a base 10 are attenuated before they have reached an active region. Those components of the alpha rays which are from sealing glass layers 11, 17 and which has a large angle of incidence with respect to the active region on the chip surface are damped to a sufficiently low level in the fluororesin layer. Alpha rays which enter the active region from a side portion of the chip 14 without passing the fluororesin layer have a small angle  of incidence so that they do not have a large working power. Thus, the amount of  alpha rays entering the active region are reduced sufficiently so that an erroneous  operation of the active region can be prevented.

Title: Noncontact charger
Inventor: UENO KAZUYA
IPC: H04W52/00
Filed: 1996-02-21
Abstract: PROBLEM TO BE SOLVED: To prevent the overcharge of a secondary battery by detecting whether a part to be charged is set or not for the charging part, and the charge condition of the secondary battery. SOLUTION: In the case where a part 2 to be charged is set for a charging part 1, magnetic fluxes are generated intermittently from an oscillating coil 5, and voltage is induced in an electromagnetic coupling coil 9. A current detecting circuit 11 detects this voltage, and an oscillating circuit 13 for control operates by the signal at the time when the CPU 12 judges that a part 2 to be charged is set for the charging part 1, and a signal is induced in the electromagnetic coupling coil 6 for control electromagnetically coupled with an electromagnetic oscillation coil 14 for control, and it gets in an oscillation control circuit 8 via a rectifying circuit 7. The oscillating circuit 8 receives this signal and switches control into the charge mode control where the oscillating circuit 4 operates continuously.  In case that CPU 12 judges that the secondary battery is in full charge condition during the charge mode control, the operation of the oscillating circuit 13 for control is stopped, so the oscillating circuit 4 operates at enough low duty ratio similar to the time when a part 2 to be charged not set for the charging part 1.

Title: Refrigerant vaporizer
Inventor: NAGASAWA TOSHIYA
IPC: F25B39/02
Filed: 1992-02-20
Abstract: PURPOSE:To equalize the temperature distribution of air flow by forming a restriction which reduces a distribution area of refrigerant flowing longitudinally at the central part between an inlet tank and an outlet tank and further reducing the shape of the restriction and the distribution area toward the downstream. CONSTITUTION:Plates 5 forming tubes which pass refrigerant are laid out longitudinally in the lower parts of an inlet tank 3 and an outlet tank 4. There are formed an U-shaped passage formation dented portion 11, a partitioning rib 18 formed in its central part, an embossed rib 17 and tank formation dented portions 12 and 13 deeper than the dented portion 11. When a pair of plates 5 are but-welded, thereby forming a passage, restrictions 15 whose distribution area is reduced toward lower part, such as reverse triangle, are laminated by several stages so that they may be doubled. As a result, gas refrigerant flows on the side of a larger distribution area above the restrictions 15 whereas liquid refrigerant flows on the side of a smaller area below, which speeds up the velocity of the liquid refrigerant and allows the refrigerant at an equalized temperature to be distributed in the row direction of the tubes.

Title: Digital video recording system
Inventor: UMEMOTO MASUO
IPC: G11B20/14
Filed: 1984-02-24
Abstract: PURPOSE:To reduce generating frequency of signal errors due to a pttern peak shift, etc., by converting a pattern into such a pattern that the prescribed number or more of ''1'' or ''0'' will not continue in terms of 8-8 mapping table for decreasing a DC component at the time of magnetic recording. CONSTITUTION:First, a pattern of n max=6 (nr=3; ns=3) is preferentially used as a 8-8 mapping table for a Y signal, and a number of quantized levels 196 are secured. For a pattern of remaining four levels, a pattern having six numbers of ''1'' among n max=7 or 8 bits is selectively used and storedin tables 8, 9 and 10. Since the necessary number of quantized levels is 224 for a mapping table for signals C1 and C2, n max=8 (nr=ns<=4) is adopted and stored in the tables 8, 9 and 10. Thus the Y signal table is satisfied with n max=6 at approximately a quantized level.
