Title: Power amplifier
Inventor: IWAI HIROSHI
IPC: H03F1/32
Filed: 1998-08-31
Abstract: PROBLEM TO BE SOLVED: To compensate nonlinear distortion to output power in a wide range by switching at least two nonlinear distortion compensation circuits in accordance with an output. SOLUTION: When the level of input power is high, a 1st nonlinear distortion compensation circuit 3 is made to conduct by 1st and 2nd switching circuits 2 and 4, and a signal having no distortion is outputted to an output terminal 7 because the change of gain and phase of the 1st nonlinear distortion compensation circuit 3 is of inverse characteristics to the change of gain and phase of an amplifier circuit 6. Also, when the level of the input power is low, a 2nd nonlinear distortion compensation circuit 5 is made to conduct by the circuits 2 and 4, and a signal having no distortion is outputted to the terminal 7 because the change of gain and phase of the circuit 5 is of inverse characteristics to the change of gain and phase of the amplifier circuit 6.

Title: Combustion device
Inventor: ISHIGURO TOSHIYUKI
IPC: F23D11/40
Filed: 1983-12-23
Abstract: PURPOSE:To prevent back fire and expand the range of the ratio of fuel and air so as to get a sufficient amount of radiation by a method wherein a top plate having a cooling top of convex form arranged at the ceiling part to be communicated with a flow regulating cylinder in a combustion cylinder is arranged so as to for an air flow. CONSTITUTION:A top plate 17 having a convex cooling top 20 to be communicated with a flow regulating cylinder 9 within a combustion cylinder 11 arranged at the top part of the gasification cylinder 1 is installed at an outer cylinder 14 and closed and a blower fan 19 is arranged at the rear part of the unit. The top part of the cooling top 20 is provided with a cooling fan 21. The premixing gas metered at the mixing plate 7 is initially pushed up as shown by an arrow toward the cooling top 20 and dispersed downwardly, resulting in that the gas is more regulated, exits from the premixing gas injection hole 8 into the regulating space 10 and thus a surface combustion flame having no irregular red heat is formed by an ignition unit within the combustion cylinder 11. The premixing gas introduced into the cooling top 20 is cooled by cooled air from the blower fan 19 at the rear part of the unit and a thermal dispersion is promoted by the cooling fan 21. The temperature of premixing gas within the flow regulating cylinder 9 is decreased by 80-90 deg.C as compared with that having no cooling top 20, resulting in that the temperature is less than 400 deg.C in all areas in respect to a variation in air fuel ratio, and it is possible to prevent a back fire and a decreasing of range of air fuel ratio.

Title: Manufacture of semiconductor device
Inventor: USUKI KIICHI
IPC: H01L21/28
Filed: 1987-09-30
Abstract: PURPOSE:To form an electrode in an excellent configuration having a specified size and to improve the characteristics and the reliability of an element, by using an etching liquid, whose HNO3 concentration in the etching liquid is a specified value or more, when the electrode is etched with the etching liquid using H3PO4, HNO3 and CH3COOH. CONSTITUTION:A hole is provided selectively by a PEP method in a semiconductor element on an Al film 3c as a third layer. When the element is immersed into a CH3COOH-H3PO4-HNO3 based etching liquid, the third-layer Al film 3c is etched. When a V film 3b as a second layer is exposed, a potential is generated between the second-layer V film and the third-layer Al film. When HNO3 concentration in the etching liquid is less than 1wt.% at this time, two kinds of the etching mechanisms are provided. Namely, when the HNO3 concentration is less than 0.5-1wt.%, the etching of the Al layer is accelerated. The difference in etching rates of Al and V is yielded. Thus, the V layer 3b becomes an overhang shape. When the liquid, whose HNO3 concentration is 1wt.% or more is used, defective phenomena can be prevented. Thus the excellent etched configuration can be obtained.

Title: Descrambling device
Inventor: OI SHINICHI
IPC: G06F21/10
Filed: 1987-09-30
Abstract: PURPOSE:To improve the security of the title device by performing a reception avoiding operation for itself, and disturbing a video signal in a scrambling condition with a terminal, which cannot receive information to permit a reception, when a signal not to permit the reception is supplied from a reception orthorizing information holding means. CONSTITUTION:When a reception orthorizing information holding circuit 18 is not permitted to be received as a piece of reception orthorizing information (a), a reception control signal (b) operates an automatic reception avoiding circuit 20, and avoides the reception. When the reception can be avoided, since a normal randam line address 17a cannot be reproduced, the signal read out from picture memories 13 and 14 is scrambled. To the scrambled signal, an interfering signal from the automatic reception avoiding circuit 20 is added. Consequently, even when the original picture can be easily guessed from the picture, which cannot be normally descrambled, signal contents are completely disturbed due to passing through the automatic reception avoiding circuit 20, and the original picture cannot be guessed completely.

The part 9 sends the received angle data to a panhead manipulator 11. Meanwhile the north error angle of the panhead 7 is stored in a storage part 5 as the north correction angle data with manipulation of a storage manipulating part 6. An operation arithmetic part 4 receives the north correction angle data from the panhead 7 when the panhead control is started and subtracts the received correction data from the present angle data to obtain the azimuth data. This azimuth data is shown at an angle display part 2 so that the coincidence is secured between the azimuth of the panhead 7 and that of the part 2.

Abstract: PURPOSE:To miniaturize a polarizing prism and to keep the characteristic by forming the exit face of the polarizing prism into a convex and widening angles of incidence of ordinary rays and extraordinary rays to the exit face. CONSTITUTION:Slopes of first and second triangular prisms 1 and 2 made of crystal are joined to constitute the rectangular parallelepiped-shaped polarizing prism.

That is, the angle approx.=2 of incidence of ordinary rays and extraordinary rays is widened by constituting the exit face B of slopes b1 and b2, and as the result, an angle theta of separation is widened.

Title: Vibration dissipation device
Inventor: YOSHIOKA SHIGEKI
IPC: F16M7/00
Filed: 1994-09-14
Abstract: PURPOSE: To always obtain sufficient reduction effect of engine vibration by decreasing change of adsorption force due to variation of size of a clearance. CONSTITUTION: In a control type engine mount, an actuator 7 is arranged with a proper clearance from a movable plate 6. A magnetic leakage portion 11 having a section composed of a triangular projection is formed on a circumference on an upper surface of a yoke 8b of an electromagnet 8 of the actuator, oppositely to an outer periphery of the movable plate 6. A spacer 12 is formed on an upper surface of the yoke 8b for preventing adsorption of the movable plate 6 to the actuator 7. When length of the clearance between the movable plate 6 and the yoke 8b is reduced, a part of magnetic flux leaks from the magnetic leakage portion 11. Attraction increase of the actuator 7 is deteriorated. Amplitude of the movable plate is substantially equalized in respect to current carrying of positive and negative currents to the electromagnet 8.  It is thus possible to always obtain sufficient vibration reduction effect, and prevent scattering of a control system.

When 25ms has elapsed, the voltage Vs across both electrodes of the cell 24 is detected (S40) and the voltage is adjusted to Vs1 (S45) and the resistance value Rs1 of the cell 24 is calculated from the voltages Vs0 and Vs1 and current Icp (S50).  After the resistance value Rs1 is calculated, the value Rs1 is compared with a preset value Rss (S55) and, when the Rs1 is smaller than Rss, it is discriminated that the cell 24 reaches an active state.
