Title: Multiplier
Inventor: DOSONO HIROAKI
IPC: G06F7/527
Filed: 1998-09-25
Abstract: PROBLEM TO BE SOLVED: To provide a repetitive multiplier which can increase its operation speed with a small-scale configuration. SOLUTION: When an 8-bit multiplicand X is multiplied by an 8-bit multiplier Y with addition of a code, the 2-bit code expansion is carried out. Meanwhile, the 2-bit 0 expansion is carried out with addition of no code. Thus, this multiplier M1 performs alternatively the multiplication with a code and the multiplication with no code. In such a constitution, a partial product generation circuit 22 generates a 1st partial product B0 corresponding to the least significant bit of the multiplier Y in a 1st cycle of operation. A partial product generation circuit 20 successively generates the partial products B1, B2... excluding the product B0 in each cycle and in the order of lower ranks.  Then the partial product that is generated by the circuit 20 in the current cycle is added to the intermediate sum that is held in the preceding cycle, so that the partial products are cumulatively added together at the circuit parts (24 to 30). An augend selection circuit 32 supplies the product B0 received from the circuit 22 to each of said circuit parts in the 1st cycle only. As a result, the cumulative addition of partial products is possible in and after the 1st cycle and the number of cycles is decreased by one.

Title: Method and equipment for pressure casting
Inventor: KURIYAMA MINORU
IPC: B22D17/22
Filed: 1999-09-27
Abstract: PROBLEM TO BE SOLVED: To solve a problem that a great deal of effort is needed to find reasonable condition by trial and error, because of no indicating for setting operational condition of the pressure plunger suitable for each metal mold. SOLUTION: In this pressure casting method wherein the cavity of a metal mold is filled with molten metal and a pressure plunger advancing in the cavity pressurizes the molten metal, the operation starting time of the pressure plunger is made to be a time standard, the mold opening amounts changing with time are previously set as a target trajectory, and the pressurizing force of the plunger is feedback controlled so as to fall an actual mold opening amount in the set one. Since the mold opening amount of the target trajectory can uniquely be set as a pattern wherein it gradually increases after starting the advance of the plunger while changing linearly to reach a maximum amount and after that, keeps the maximum, no complicated trial and error is needed to set he operational condition of the pressure plunger.

Title: Color television
Inventor: MOROHASHI KATSUE
IPC: H01J29/07
Filed: 1988-10-27
Abstract: PURPOSE:To improve color reproducibility by providing a magnetic layer magnetized in the direction parallel to a face orthogonal to a tube-axis in the vicinity of an open-end portion of a shadow mask to restrict color dispersion or decrease of color purity. CONSTITUTION:A shadow mask 11 is set as facing a fluorescent screen 9. A magnetic layer 14 is provided in a main face of the shadow mask 11 except an open-end portion 10. The magnetic layer 14 is so magnetized in the direction parallel to a longitudinal direction of a fluorescent layer 7 that an electron beam 15 passing through the open-end portion 10 collides with a correct fluorescent layer 7. Thus, a magnetic field 16 heading for a rear face from a front face of the figure is generated. Accordingly, the electron beam 15 passed through the open-end portion 10 is slightly bent to collide only with a correct fluorescent layer 7b. Therefore, there is no color dispersion and color reproducibility is improved.

Title: Continuous casting method
Inventor: MATSUKAWA TOSHITANE
IPC: B22D11/128
Filed: 1985-12-02
Abstract: PURPOSE:To prevent the cracking at the solidification boundary and to permit high speed casting by using hourglass-shaped rolls for upper pinch rolls at the leveling point of a curved type continuous casting machine and cooling rolls on the inner side of the arc more strongly than the rolls on the outer side thereby casting an ingot. CONSTITUTION:The rolls of the hourglass shape as a whole which are recessed in the surface so as to be made smaller in the diameter in the central part than the diameter of both side parts are used for the pinch rolls 5 positioned on the inner side of the arc of the ingot. The pinch rolls 5 have the hourglass shape and therefore, the bulging part generated in the non-supporting zone of the ingot is given drawing power as both right and left sides of the ingot are rolled down but the central part is not rolled down. The rolling down strain is thus made zero or suppressed to the small value approximate to zero. The leveling strain is further decreased by making combination use of the differential cooling on the top and bottom surfaces therewith, by which the total strain is decreased and the casting speed is increased.

Filed: 1989-10-20
Abstract: PURPOSE: To reduce a noise even if rotating speed is raised, by having a belt touching a roller at both ends thereof and preventing the belt from touching the roller in a middle part thereof. CONSTITUTION: A buffering roller 1 with teeth has a flange 3 at an edge thereof and a pair of teeth 4, 5, which are parallel to each other and have same diameters, formed on the periphery thereof. A groove 2 is formed on the peripheral of the buffering roller 1 so as to separate a pair of teeth 4, 5 from each other, and the diameter of the groove 2 is smaller than the inner diameter of the teeth 4 or 5. Teeth 7 engaged with the pair of teeth 4, 5 on the buffering roller 1 are formed on the inner surface of a belt 9. A slat 8 horizontally extending is fixed on the outer surface of the belt 9.  The buffering roller 1 is not completely engaged with the inner surface of the belt 9 in the cross direction, but the only parts which teeth 4, 5 are formed on are engaged. therefore, the contact surface of the buffering roller 1 and the belt 9 becomes narrower, the axial interval of the corresponding pair of rollers remains constant, and no affect is given to supporting the slat 8. When the buffering roller 1 rotates around the axis 6, the belt 9 is driven, so that the traveling noise is reduced.

During this period, the output of a comparator IC 2 becomes a high level with repeating this blocking oscillation and a capacitor C5 is continuously charged so that the transistor Q5 is kept on and the oscillation halt is maintained.  After detecting the unloaded state, the desired number of blocking oscillation is performed and the oscillation halt is maintained so that stress placed on a constituent elements of a lighting circuit can be suppressed, this device can be easily actuated when the electrodeless discharge lamp is at low temperature or the first starting, and the generation of harmonic noise when starting can also be suppressed.

Abstract: PURPOSE:To measure the concn. of a low-concn. radioactive gas right after a high-concn. gas by providing a means for preventing adsorption of the radioactive gas by a narrow air flow gap or gas impermeable membrane to the light shielding film side of a plastic scintillator. CONSTITUTION:The air flow gap 27 is provided as the means for preventing the adsorption of the radioactive gas to a detector. A gas to be measured is introduced by an outside pump into a gas sampler 22 and the plastic scintillator 33 is made to emit light by the beta rays transmitting the vapor deposited Al 'Mylar(R)' 26 of a window 25. The light thereof is converted to an electric signal by a photocell 34. Said signal is applied as an electric signal of the magnitude proportional to the quantity of the beta rays to a wide range electronic circuit 36. A flow rate regulating valve 29 is held open during the measurement so that a room gas is passed through a filter 28 into the gap 27. The rare gas past the 'Mylar(R)' 26 from a sampler 22 is removed together with the flow gas passing in the gap 27, by which the adsorption of the rare radioactive gas on the surface of the scintillator 33 is prevented.
