Title: Submerged bearing
Inventor: SHIMIZU HITOSHI
IPC: F16C33/76
Filed: 1983-03-25
Abstract: PURPOSE:To have a bearing with long life, which serves in a corrosive liquid, by forming the vessel as having an opening at the bottom of a vertical rotor set in the liquid, supporting the rotor by a bearing installed in the vessel, introducing a gas into the vessel, and thereby allowing the bearing to work without contact with the liquid. CONSTITUTION:A stationary shaft 2 formed at the bottom surface of a liquid sump 1 is provided with a gas inlet 3 and a bearing 4. A vessel 7 is formed at the tip of an impeller shaft 6 to agitate the liquid 5 driven by a driver, and is fitted in said bearing 4. Gas 9 is fed to this bearing part 8 from outside, and when the gas pressure is set over the liquid pressure head at the undersurface of the vessel, no liquid 5 will intrude to the bearing part, so that corrosion of submerged bearing is prevented even in case the liquid 5 is corrosive.

Title: Structure for battery cover
Inventor: NISHIJIMA YASUNORI
IPC: H01M50/271
Filed: 1988-03-03
Abstract: PURPOSE:To prevent a cover from being broken when applied with a pressing force while in the opened state by openably fitting the battery cover to the insertion port of a battery case via the first hinge section and making it foldable in the opening direction of the battery cover via the second hinge section. CONSTITUTION:A battery cover 22 has the first hinge section 24 and the second hinge section 26. The shaft 25 of the first hinge section 24 is located in a long hole 28 formed on the main body side and slid in the long hole 28 during the opening or closing operation. On the other hand, the second hinge section 26 is constituted as a thin section 27 on the battery cover 22 made of plastic, it is not folded in the closing direction of the battery cover 22 because protruded pieces 26A and 26B touch together, but it can be folded in the opposite direction, i.e., in the opening direction of the battery cover 22. When the cover 22 is applied with a pressing force while in the opened state, the cover 22 is folded to the outside via the second hinge section 26, no strong force is applied to the first hinge section 24. The first hinge section is prevented from being broken by a lever action.

Title: Sound decoding device
Inventor: MATSUMOTO ICHIRO
IPC: H04B14/06
Filed: 1995-02-16
Abstract: PURPOSE: To reduce a sense or incompatibility that the tone color of the pseudo background noise in a silent section is unnatural when quick disturbance in one frame occurs just before the stop of transmission due to the change from a sound section to the silent section in the case of reception and decoding of a signal subjected to adaptive difference PCM encoding. CONSTITUTION: A demodulated signal (a) from a reception demodulator 2 is demultiplexed to encoded data (c) and a sound detection flag (b) indicating the presence/absence of sounds by a demultiplexer 3. A prediction coefficient (g) used to decode the encoded data (c) in an ADPCM decoder 5 is extracted by a prediction coefficient holder 6 and is averaged in each frame and is given to an auxiliary prediction coefficient holder 7, and this holder 7 always successively calculates the average value of a prediction coefficient average value g' in plural frames and holds it. When changing to the silent section, the held average value in plural just preceding frames is given to the ADPCM decoder 5 to decode the pseudo background noise.

IPC: H03G1/00
Filed: 1983-03-28
Abstract: PURPOSE:To attain the small power consumption and to improve the frequency characteristics of gain attenuation for a gain varying circuit with a simple constitution, by constituting a power supply switch circuit with a dual FET and a transistor (TR) functioning as a fixed voltage source and controlling the current of a diode set at the drain side of said FET. CONSTITUTION:A dual gate FET26 is added to a gain varying circuit, and the fixed voltage which is divided by resistances 39 and 40 is applied to the base of a TR41. Then resistances 42 and 43 are connected to the emitter of the TR41, and the TR41 is used as a fixed voltage source. A pin diode 44 is connected between the collector of the TR41 and the FET26, and an output 36 is connected to the cathode side of the diode 44. At the same time, the cathode of the FET26 is earthed in terms of a high frequency and then connected to the emitter of the TR41. Thus a switch circuit is formed with the FET26 and the TR41, and therefore the current of the diode 44 is controlled. The power consumption is reduced with this simple circuit constitution, and the frequency characteristics of the gain attenuation can be improved.

Title: Amplifier of pulse duration modulated signal
Inventor: BABA KIYOUJI
IPC: H03F3/217
Filed: 1980-04-17
Abstract: PURPOSE:To reduce the consumption of electric power, by varying the driving power of the amplifying stages preceding the driving stage that drives an output stage in accordance with the amplitude of a modulated signal. CONSTITUTION:The input signal supplied to a terminal 1 receives a modulation of pulse duration through a pulse duration modulating circuit 2 to be supplied to the base of a driving transistor (TR)3. Thus output TRs 4a and 4b are driven. The current of a TR31 varies by a change of the collector current of a TR17a to which the input signal is supplied. In this case, the current also varies for a TR29 that forms a current Miller circuit along with the TR31. Then the current corresponding to the collector current of the TR31 is supplied to the TR29 to be used as a power source of the TR4a. In other words, the voltage that drives an output TR is reduced when the amplitude of the input signal is small.

Abstract: PURPOSE:To obtain a thermal contraction pipe being excellent in a contractivity, by a method wherein a crosslinked plastic tube is heated by an induction heating and is also expanded by an air pressure. CONSTITUTION:After a core 2 is covered with a tube 1 whose one end is closed with a thermoplastic tube such as crosslinked polyethylene, polyvinyl chloride, etc., an open side of the plastic tube 1 is fastened on a core 2 by a fastening means 8.

Simultaneously, compressed air is pressed into the inside of the core 2 through an air feed pipe 7 to expand the plastic tube. Since an expansion of the plastic tube is limited by a molding die 3 thereupon, the tube is formed in an approximately cylindricity on the whole. The heated, expanded plastic tube is then cooled by a cooling water to obtain a desired thermal contraction pipe.
