Title: Transmission panel
Inventor: MATSUOKA RYOJI
IPC: H04B1/04
Filed: 1987-08-18
Abstract: PURPOSE:To reduce the local leak at the lower level of an input signal by using 1st and 2nd attenuation means in combinations provided among an amplifier system of the input signal, a local oscillation means and a frequency converting means so as to control the leakage of a local oscillation frequency from the local oscillation means generated at the input level reduction of the microwave. CONSTITUTION:The 1st and 2nd attenuation means 30, 80 comprising an element whose impedance is changed by a bias current and varying its attenuation in response to the output level of a transmission panel 300a are provided respectively among the amplifier system of the input signal, the local oscillation means 70 and the frequency modulation means 20. If a gain reduction in each function block of the amplifier system arranged before the 1st attenuation means 30 and the input signal are reduced, the output of the local oscillation means 70 and the attenuation of the amplifier system of the input signal 1 are controlled by the same condition by means of the voltage obtained through the detection of the output. Thus, the local leak caused by the gain reduction of each function block of the amplifier system arranged before the 1st attenuation means 30 and the input signal is reduced.

Title: Sliding type ship hull
Inventor: PIITAA JIEI BAN DEIIPEN
IPC: B63B1/04
Filed: 1994-08-03
Abstract: PURPOSE: To reduce the amount of wash generated when a ship is traveling at high speed by positioning chines so that in a lateral projection the chine 2 is located below the chine 1 at the bow, intersects the chine 1 at the center of the hull, and is located above the chine 1 at the stern. CONSTITUTION: This hull characterized by the intersection of an upper chine 1 and a lower chine 2 in a side view. As a result, an outer bottom plate 4 is twisted from a deep V-shape forward to a shallow inverted V-shape aft. The effect of the twisted outer plate 4 is a combination of very deep V-sections forward, resulting in an excellent seakeeping characteristic in waves at high speed, with a highly effective lifting surface aft. The outer bottom plate 4, together with an inner bottom plate 5, forms bottom channels in the aft portion of the bottom of the hull, in which an air/water spray is limited to reduce the spray and waves outside the ship. Friction resistance below the hull is reduced at the same time.

Title: Bonding thin wire with insulating coat for semiconductor and manufacture thereof
Inventor: TATSUMI KOHEI
IPC: H01L21/60
Filed: 1989-08-09
Abstract: PURPOSE:To contrive improvement in the insulating property, the heat resistance and the wear resistance of an insulating layer, as well as in the bonding property by coating the surface of a thin wire made of a metal with an inorganic substance uniformly. CONSTITUTION:A synchronous rotation transmission device 13 rotates a shaft 14 by an external power and transmits this rotating force to gears 5, 9 and 17 through fixed gears 15, 16, and 19. The gears 5 and 9 rotate synchronously to rotate supporting tables 6 and 7 as well as reels 2 and 3 attached to said supporting tables regarding stopper shafts 5' and 9' as a center respectively at an equal speed. At the same time, the reel 3 rotates regarding a shaft 10 as a center through transmission gears 8, 11, and 12 and accordingly a thin wire wound and stored around the reel 2 rotating freely is drawn and the thin wire is moved to the reel 3 while being rotated continuously and is wound on the reel 3. The above described device is set in a vacuum tank for dry coating and the thin wire passes through a vapor deposition region of an inorganic substance and thereby the thickness of the deposited film does not become different. The thicker the film thickness of the insulating inorganic substance is, the surer its insulating property is. However, for account of an even balance of the insulating property and the bonding property, a range of a proper thickness exists for each coating substance.

Filed: 1983-10-31
Abstract: PURPOSE:To obtain an automatic cassette loading device simple in constitution of a vertical moving mechanism by obtaining the relation of a cassette supporting body to the vertical moving mechanism from the engagement of an ascending/descending arm engaged with a specifically shaped cam providing vertical movement with a pin of the cassette supporting body. CONSTITUTION:A cam pin 106 is planted on the ascending/descending arm 88 so as to be turned to the side of a worm wheel part 46. The cam pin 106 is engaged with a scroll cam 108 formed on the turning surface of a gear part 52. The spiral cam 108 is constituted of two stages, i.e. a circular groove 108a and a spiral groove 108b generated from a part of the circular groove to the turning center, and even if a cam gear 42 is rotated, the cam pin 107 slides only on the outermost peripheral circular groove 108a and does not generate force pressing the arm 88 downwards. When the guide pin 82 is unlocked from a lock arm 96 and the guide pin 82 slightly presses the arm 88 downwards, the cam pin 106 is engaged with the spiral groove 108b and the spiral cam 108 depresses the arm 88. Thus, the cassette supporting body 6 is vertically moved.

Title: Solid-state image pickup element
Inventor: WATANABE TORU
IPC: H04N5/353
Filed: 1989-08-09
Abstract: PURPOSE:To prevent malfunction of a signal processing circuit by supplying a 1st sampling clock to a 2nd sample-and-hold circuit while a charge is transferred in a vertical register at a high speed and supplying a 2nd sampling clock to a 2nd sample-and-hold circuit for the remaining period. CONSTITUTION:Sampling clocks SC1, SC2 are fed selectively to a sample-and- hold circuit 3. That is, the sampling clock selected by a selection circuit 10 is fed to the sample-and-hold circuit 3b and the selecting operation of the selection circuit 10 is controlled by a selection pulse CP generated from a selection control circuit 11. Thus, the timing of the sample-and-hold of each sample-and- hold circuit is made coincident for a period when noise is easily superimposed on a video signal, that is, for a period when the charge is transferred in the vertical direction at a high speed to make outputs of 1st and 3rd sample-and- hold circuits the same in the waveform. Thus, both outputs of a differential amplifier are cancelled and noise is suppressed.

CONSTITUTION:For a mushroom valve for an internal combustion engine, a hollow valve in which a filler made of metal (metallic sodium, for example) which is liquefied at least at a working temperature is sealed in order to exclude heat from a high temperature part is used. In this case, in order to produce the hollow valve, body 10 consisting of a valve stem 1 and a valve head 2 and a valve head part 1a are finished by machining and metallic sodium and so on 3 is sealed in a hole 1b of the valve body 10. Then, electron beam welding is executed in a vacuum for fixing the valve body 10 and the valve head part 1a to each other so as to form a vacuum part in the through hole 1b, and the outer surface is finally finished for completion. Accordingly, transfer of a filler of the metallic sodium and so on 3 with temperature change of the valve is facilitated, and a function as a heat pipe is increased.

Abstract: PURPOSE:To allow the control of a film thickness without generating noises with a hot dip metal coating device for approximately vertically pulling up a sheet material to be coated by specifically providing 1st to 3rd high-frequency coils to the sheet material to be coated. CONSTITUTION:The sheet material 1 to be coated is pulled up with the sheet surface positioned vertically from the inside of a molten metal 3 and is cooled to solidify the molten metal, by which the material is coated. The 1st coil 4 which horizontally encloses the plate material 1 above the liquid level of the molten metal 3 and the 2nd and 3rd coils 5a, 5b which are disposed approximately symmetrically on both sides of the sheet surface of the sheet material 1 and the coil 4 and have the axis approximately perpendicular to the sheet surface mentioned above are provided in this device. The high-frequency current of the same phase is supplied to the 1st to 3rd coils to generate eddy currents in the liquid films sticking to the surface of the sheet material. Magnetic fluxes are passed in the eddy currents to generate downward force and to reduce the thickness of the liquid film. Since the magnitude of the above-mentioned force is determined by the high-frequency current flowing in the coils, the film thickness is controllable by adjusting the high-frequency current.
