Title: Lighting device of discharge lamp
Inventor: YAMADA KOJI
IPC: H05B41/24
Filed: 1991-06-25
Abstract: PURPOSE:To secure the operation of a starting circuit in a replacing time, by connecting a circuit to oscillate and maintain an inverter device in an abnormal condition of a discharge lamp to both ends of a capacitor, and resetting the maintaining circuit in the replacing time. CONSTITUTION:When a discharge lamp is removed, a DC circuit is cut off, the partial potential voltages of resistances R13, R15, R14, and R16 are reduced, a current flows to a transistor Q8 through diodes D5 and D6, and the transistor Q8 is turned on. In this case, the maintaining current of a thyristor Q4 is cut off to turn off the thyristor Q4, and the oscillation of an inverter device is stopped. However, since the discharge lamp has been removed, the transistor Q8 is left being ON, and the voltage of a capacitor C1 for starting is not raised. And only when the discharge lamp is inserted, the voltage of the capacitor C1 reaches to the breakover potential of a trigger element Q3, a starting pulse signal to turn on a transistor Q2 is given, and the oscillation of the inverter device is started.

Title: Nitrided cast iron parts subjected to sealing treatment and its production
Inventor: MORISHITA TSUYOSHI
IPC: F02F1/00
Filed: 1982-09-03
Abstract: PURPOSE:To obtain nitrided cast iron parts having improved corrosion resistance and sliding characteristics by polishing the surface of a nitrided cast iron base material and sealing the clearances between the exposed graphite and the base material by using a resin contg. a solid lubricant. CONSTITUTION:When a cast iron blank material is subjected to a soft nitriding treatment, a compd. layer 10 is formed on the surface thereof and build-ups are produced in the parts 12 of graphite simultaneously with hardening, thus forming clearances between said parts and a base material part 14. After the build-ups on the surface are polished away, a resin such as epoxy resin which contains 30-80vol% a solid lubricant and does not decompose at <=250 deg.C is coated thereon and is rubbed. The material is then subjected to a heat treatment to form a resin layer 15 on the surface of the material 14 and to seal the clearances. Even if the layer 15 is collapsed by sliding with a piston or the like, the layer remains as a resin part 16 in the exposed part of the graphite 12 and provides a sealing effect.

As to this region, the video data is coded by using the primary dimension level plane coding method as a multi- value data. On the other hand, as to the non-intermediate tone region B, the video data is coded by using the modified read coding method as the binary data. Thus, as a whole the transmission efficiency can be increased.

Title: Contact type image reader
Inventor: OTSUKI SHINICHIRO
IPC: H04N1/04
Filed: 1986-07-02
Abstract: PURPOSE:To process paper or the like through one procedure by rotating a background conveyance roller with the rotary shaft of a gear as a center. CONSTITUTION:A background roller 2 pressed against a reader 1 is engaged with a drive gear 3 through the gear 2a and rotates the rotational center of the drive gear 3 as a center. When the paper or the like 5a is pulled in the direction of an arrow 9a, the background roller 2 moves upward together with the pulling and lies in a position 2'. For conveying the paper or the like 5b, the driving gear 3 rotates in the direction of an arrow 9c, and consequently the background roller 2 rotates as an arrow 9b. Therefore the background roller 2 is contained in its original position due to the frictional force between itself and the reader 1, the rotational force of the driving gear 3 and gravitation, and a pressing part 6 is secured. When a teared or jammed paper is handled, it is pulled out of the outlet of the reader, and therefore one procedure is sufficient for processing.

Title: External force measuring device of shield excavator
Inventor: OISHI YOSHIHIRO
IPC: G01B7/16
Filed: 1991-06-26
Abstract: PURPOSE:To measure external force acted on an excavator body accurately, to promote durability of a measuring section and to detect slope directional resultant force, axial resultant force and circumferential resultant force without requiring any special sensor. CONSTITUTION:External force such as slope directional resultant force (earth pressure, water pressure), axial resultant force (frictional force or shearing force), circumferential resultant force (rolling reaction force), etc., acted on an excavator body (skinplate) 2 are received by a pressure receiving plate 3a of each of external force measuring sections 3 and are transferred to strain gauges 3e and 3f of a load detection section 3b to measure.

Title: Echo canceller circuit for full duplex modem
Inventor: MIYAMOTO RYOICHI
IPC: H04B3/23
Filed: 1989-06-19
Abstract: PURPOSE:To simplify the structure of an echo canceller circuit and to effectively cancel near end and far end echoes without being influenced by a time-varying element by individually forming the pseudo signals of the near end and far end echoes through different filters. CONSTITUTION:Application filters are divided into near end and far end echo canceller adaptive filters 21, 22. A bulk delay 20 is connected to the input stage of the filter 22 to hold a time difference required for the return of a far end echo F from a transmission point of time. Thereby, a sending signal S for forming a far end pseudo echo component is effectively inputted to the filter 22. Thereby, the number of taps of the filter 22 can be reduced. The output of the filter 22 is inputted to a phase follow-up circuit 23 to allow the input signal to follow up the frequency of an error signal E. Thereby a pseudo signal, i.e., a far end echo canceling signal SE, formed from the circuit 23 is allowed to further approximate to a practical far end echo. Consequently, a time-varying element such as a frequency offset and a phase jitter to be applied to the far end echo on a transmission line can be effectively canceled.

Title: Reactor recirculation pump
Inventor: CHIBA YOSHIAKI
IPC: G21C15/243
Filed: 1992-06-15
Abstract: PURPOSE:To suppress thermal stress generation and thermal expansion by providing vibration prevention part placed on a sleeve with an air path hole and promoting circulation and natural convection of heated air. CONSTITUTION:In the pump nozzle 6 provided on a head plate at the bottom of a reactor pressure vessel, a sleeve 7a of a pump casing 7 is coupled. A vibration prevention part 12 is provided around the sleeve 7a, which contacts the inner surface of bottom end of the pump nozzle 6. The pump nozzle 6 is heated up by reactor water during operation. The heated air in the gap 8 circulates by thermal convection due to the temperature difference between both wall surfaces of the pump nozzle 6 inner surface and sleeve 7a outer surface. It passes through air paths 13a, 13b, 13c and 13d provided in the vibration prevention part 12 and therefore, the heated air in the gap 8 and the exterior air are replaced and thermal convection is promoted. As the both wall surfaces of pump nozzle 6 inner surface and sleeve 7a outer surface are evenly cooled by the circulation of the exterior cool air, ununiformity of temperature distribution is moderated.

Abstract: PURPOSE:To sharpen a charge distribution and to decrease sticking of the toner to the non-image part of a photosensitive body and staining of the inside of an electrophotographic copying device by subjecting toner particles to a heating treatment at the temp. below the glass transition temp. of a binder resin. CONSTITUTION:The toner particles are formed by kneading the binder resin and coloring agent and grinding the mixture and an external additive is added thereto so as to be stuck to the toner particles.
