Abstract: PURPOSE:To manufacture a metallic tube having different kinds of metal layers in high dimensional accuracy and good joining condition by sticking molten metal to the inner peripheral surface of a metal layer by centrifugal force of the poured molten metal and forming the different kind of metal layer on the inner surface of the metal layer. CONSTITUTION:A mold 10 is supported so as to be possible to rotate around the horizontal axis. While rotating the mold 10, the molten metal is poured into the mold 10. The poured molten metal is formed into the metal layer 20 along the inner peripheral surface of the mold 10 by the centrifugal force according to the rotation. Further, while rotating the mold 10, the different kind of molten metal is poured into the metal layer 20 in the mold 10, and this molten metal is stuck to the inner peripheral surface of the metal layer 20 by the centrifugal force according to the rotation of the poured molten metal to form the different kind of the metal layer on the inner surface of the metal layer 20. By this method, the thicknesses of the metal layers can uniformly be cast.

IPC: G03G21/00
Filed: 1999-04-09
Abstract: PROBLEM TO BE SOLVED: To make it possible to surely remove the objects to be drawn and to permit stable regeneration of films by taking up a long-sized cleaning material having liquid absorbability into pressurized contact with the film surfaces. SOLUTION: The cleaning liquid stored at ordinary temperature in a cleaning liquid tank 5 is dropped in a specified amount to the central parts in the transverse direction of the films in the central parts and rear parts of the films after the front parts of the film pass a nozzle 4 on the toner image recording surfaces of the films by the nozzle 4. The cleaning liquid made hemispherical on the films is applied and spread over the entire part in the transverse direction of the films by capillarity simultaneously when the cleaning liquid comes into contact with a coating application roller. The films are wiped by roll paper 7 which is a cleaning material.  The pressure contact rollers 9A and 9B of the roll paper 7 come into pressurized contact with the films after the passage of the front parts of the films not coated with cleaning liquid and wipe away the cleaning liquid in the central and rear parts of the films. The films subjected to the cleaning in the central and rear parts are gathered in an outlet tray 11. The front and rear are reversed and the films are retransferred into a feed tray 1 and the similar procedures are repeated in order to regenerate the entire part of the films.

Abstract: PURPOSE:To prevent scattering of toner from a transfer material at the time of separation, and to enable destaticization of the surface of a holder of the transfer material, by corona-discharging from a pair of corona dischargers arranged near a separating claw. CONSTITUTION:Corona discharge is applied with the pair of corona chargers 5, 6 sandwiching the support 2 of a transfer material 3 arranged near the separating claw 7 to the transfer material 3 to be separated from the support 2. As a result, the tone is separated from the transfer material 3 without scattering, and at the same time the surface of the support 2 is destaticized to carry out good multiple transfer or the like without offset. An exclusive destaticizer for the support 2 can be dispensed with, thus permitting simplification of the structure of the transfer device and reduction of its size.

Filed: 1981-07-02
Abstract: PURPOSE:To reduce final error, by recording a data from digital information with error detection and encoding together with a synchronizing signal added with a start and a stop bit at each block and performing a specified reproduction and error recorrection. CONSTITUTION:A start-bit 1 in 3-bit and a stop-bit 3 in 2-bit are added before and after an encoded data 2 in 32-bit obtained from digital information through error coding and recorded on a video disc 10 together with a synchronizing signal.

Title: Absolute value circuit
Inventor: ISHIGAKI YUKINOBU
IPC: H02M7/21
Filed: 1981-07-02
Abstract: PURPOSE:To simplify the constitution of an absolute value circuit with a reduction of cost, by combining the positive and negative polarity half-wave linear detecting circuits together. CONSTITUTION:The input signal fed to an input terminal 11 has the positive polarity and is accordingly amplified by an inverting amplifier 12 after passing through the resistances R7 and R8 to be turned into the negative polar at the output terminal of the amplifier 12. As a result, the diodes D4 and D3 are turned off and on respectively, and an end of the resistor R8 at the side connected to the amplifier 12 is equivalently earthed. In case the input signal is negative polar, this signal is amplified by the amplifier 12 after passing through the resistances R7 and R8 and turned into a signal of positive polarity at the output terminal of the amplifier 12. Accordingly the diodes D3 and D4 are turned off and on respectively, and no voltage is generated across the resistance R8. Thus no output signal is obtained at the output terminal 13.

Title: Radiator
Inventor: HONDA ICHIROU
IPC: F28F1/00
Filed: 1979-08-14
Abstract: PURPOSE: To enhance the cooling efficiency by a method wherein an inner pipe for a high-temperature liquid is provided at the bottom portion of a finned outer pipe in such a manner as to be immersed in working liquid, and the space between the inner and outer pipes is decompressed and filled with the working liquid, in a radiator for cooling a high-temperature gas or the like.  
     CONSTITUTION: When a high temperature gas is flowed into an inner pipe 4, a working fluid 7 present in the proximity of the inner pipe 4 or the working fluid 7 fed to the upper portion of the inner pipe 4 by the capillary action of a wick 5 is heated. Since the interior of an outer pipe 6 is reduced in pressure, the working fluid 7 boils and evaporates at a low temperature, and the resulting vapor condenses into liquid on the inside surface of the outer pipe 6 and returns to the bottom portion of the outer pipe 6. The heat released at the time of condensation is radiated into the air through fins 8. Accordingly, with a simple structure, it is possible to prevent carbon and the like from depositing on the parts of path and to enhance the cooling efficiency.

Filed: 1997-04-08
Abstract: PROBLEM TO BE SOLVED: To improve the overall data transfer throughput by performing the switching of antennas even when the signal and noise levels of other stations exceed the field intensity level near the center frequency. SOLUTION: The output side of an AGC amplifier 119 is connected to a narrow band pass filter 124 which extracts only the one that is near the center frequency in particular among those received signals and then connected to a 2nd detector 125, and the field intensity S1 of output level of the filter 124 is detected.

Title: Japanese sentence processor
Inventor: YAMADA HIROSHI
IPC: G06F17/22
Filed: 1990-04-19
Abstract: PURPOSE:To shorten the KANA (Japanese syllabary)/KANJI (Chinese character) conversion processing time and to produce the sentences with no limitation of expressions by providing a conversion part to convert the reading information into the KANA-KANJI sentences and a flag updating part to update the flags for each word group of the same group No. CONSTITUTION:A conversion part 3 converts the character strings into the KANJI-KANA sentences and outputs the conversion result to an output part 2. When an input part 1 produces an instruction for correction of the present output result, the correction is given to the selection of homonyms based on the instruction. Then the corrected conversion result is given to a flag updating part 6. The part 6 searches the words having the same group No 10 as 'combination' out of a word dictionary 4 and sets the using flags of these words at 0. Therefore only 'combination' is retrieved when the word having the Japanese reading 'KUMIAWASE' is retrieved next. Thus the word storage capacity is reduced and the sentence processing time is shortened. As a result, the sentences of various expressions can be produced with no increase in the storage capacity nor deterioration of the processing speed.
