Title: Improvements in or relating to reactance valve circuit arrangements
Inventor: BICKERS ARTHUR
IPC: H03J7/04
Filed: 1953-01-08
Abstract: 744,901. Automatic frequency control systems. MARCONI'S WIRELESS TELE GRAPH CO., Ltd. Nov. 27, 1953 [Jan. 8, 1953], No. 658/53. Class 38 (4). [Also in Group XL (c)] In a reactive valve circuit the control grid is connected to earth or a point of constant high potential, so forming an electrostatic shield between the anode and cathode, a resistance R is connected between the anode and cathode and a reactance X between the cathode and control grid, so forming a quadrature phase drive to the cathode relative to the grid. The capacitive coupling between anode and cathode being thus very small the quadrature phase relation between anode/cathode and cathode/grid voltages is maintained up to very high frequencies. Chokes ARFC and KRFC may load the anode and cathode circuits (Fig. 2). The modulation or control voltage M may be applied to the cathode (Fig. 1) or the control grid (Fig. 2), BPC being a by-pass condenser for other than modulation frequencies. In a modification of Fig. 1 the cathode/grid capacity CGK alone forms the reactance X and the modulation M is applied to the cathode through a transformer and a high-frequency choke.

Title: Cache memory control system
Inventor: YOSHIMUNE KAZUO
IPC: G06F12/08
Filed: 1984-01-05
Abstract: PURPOSE:To exclude a faulty completion of processing and to attain the automatic degeneration processing by providing the error check bits to both a cache memory and a cache directory respectively, and performing the error checks of the memory and the directory when a data read-out request is fed from a CPU. CONSTITUTION:A selection signal SEL is set at 1 when the data bits read out of hit detecting circuits 40 and 41 are coincident with an upper address signal ADH and also when both error detecting circuits 32 and 30 and 33 and 31 detect no error. Thus a selection circuit 6 selects the data bits read out of block groups 10 and 11 and outputs a signal DAO to a CPU. In other words, the data bits read out of the groups 10 and 11 are sent to the CPU in response to hit signals HIT0 and HIT1. The signal SEL of logic 1 is supplied to a control circuit in an error storage/control circuit 7. The circuit 7 sends a reply signal RPY to the CPU in response to the signal SEL.

Title: Brushless dc motor
Inventor: TAKABA YOSUKE
IPC: H02K29/00
Filed: 1987-01-07
Abstract: PURPOSE:To remove torque ripples, by providing multiple magnets on the circumference of a rotor yoke having a required air gap to a stator core and by forming the face flatly which stands opposite the air gap of magnets. CONSTITUTION:Multiple magnets 10 are arranged on the outside circumference 7a of a rotor yoke 7. The opposite surface 10a of the magnet 10 facing an air gap section 12 is formed in plane. Consequently, the near the air gap section 12 gets to the shoulder section 10b of the magnet 10 which lines between the end face 3a A of each tooth section 3a of a stator core 3 and the outside circumference 7b of a rotor 11, the narrower it becomes, while the nearer generating torque approaches to the shoulder section 10b, the higher it becomes. It is, however, set off by the drop portion of torque at the normal shoulder section, so that the drop amount of torque at the shoulder section 10b will increase. The torque generation in a flat characteristic condition can thereby be obtained and the torque ripples reduced.

Title: Diversity receiver after detection
Inventor: NAKAMURA SATOSHI
IPC: H04B7/08
Filed: 1992-01-07
Abstract: PURPOSE:To reduce the power consumption and to prolong the continuous reception by turning off the power supply in the reception series providing the bad reception state if the signal selecting the reception series is not changed for more than the constant time. CONSTITUTION:Reception sections 11 and 12 send the intensity of the reception electric field of the modulation wave and demodulation sections 12 and 22 send the phase margin. A level comparison diversity section 3a comparing the intensity of the reception electric field from the reception sections 11 and 12 and selecting the modulation signals of the modulation sections 12 and 22 corresponding to the reception sections 11 and 12 sending the intensity of the maximum reception electric field is provided. A power saving means 5a turns off the power supply to the unselected reception and demodulation sections when the inputted intensity of the reception electric field is higher than the set threshold value and it is detected that the corresponding modulation signals are selected for more than the set time in succession. When it is detected that the inputted intensity of the reception electric field is lower than the set threshold value, the power is supplied to the reception and demodulation sections turning off the power supply. Thus, the continuous reception is prolonged.

Title: Illuminating device
Inventor: KASHIWAGI KAZUO
IPC: G03B27/14
Filed: 1984-01-06
Abstract: PURPOSE:To reduce the variance of illuminance by constituting a device with a lamp where one half face of a lamp bulb is formed to a diffusing face and the other half face is made transparent, a mirror having a curved surface which converges the light transmitted through the transparent face from a light emitting body to the position of the light emitting body or near it, and a condenser lens. CONSTITUTION:The light emitted from a filament 11 of an illuminating lamp 6 toward a transparent wall surface 9b is reflected on a mirror 7 formed to a spherical surface and passes the transparent wall surface 9b again, and a filament image is formed in a position approximating the position of the filament 11, and the reflected light goes toward a condenser lens 8. The reflected light and the direct light from the filament 11 go to the condenser lens 8, and they are diffused by a diffusing part 9a of the wall surface of the illuminating lamp. As the result, the variance of distribution of the quantity of light generated by the shape of the filament is averaged, and ruggedness of the distribution of the quantity of light is eliminated in the light projected onto the final screen through the condenser lens 8.

Title: Optical scanning device
Inventor: OKURA MASAYOSHI
IPC: G02B7/00
Filed: 1996-01-08
Abstract: PROBLEM TO BE SOLVED: To obtain an optical travel device which can absorb the deflection of an optical box due to temperature variation without lowering the vibration performance of the optical box with a simple structure. SOLUTION: The optical box 12 in which optical components are built is provided with thin leg bodies 36 and 38, and the optical box 12 is fixed to a main body frame 44 through the leg parts 36 and 38. Since those leg bodies 36 and 38 are fixed with a screw 48, the vibration performance does not decrease and deterioration in picture quality can be prevented. Further, the optical box 12 can easily be fixed to the main body frame 44. If the optical box 12 expands or contracts owing to temperature variation, the vertical piece 38A of the leg body 38 elastically deforms by being pressed by the optical box 12 to absorb stress applied by the expansion or contraction of the optical box, and consequently the deflection of a bottom plate as the fitting surface for the optical components is suppressed to prevent the optical axis from shifting.
