Title: Motor
Inventor: OKUMA SHIGERU
IPC: H02K21/16
Filed: 1997-04-11
Abstract: PROBLEM TO BE SOLVED: To make gentle the variation of reluctance torque incident to rotation of a rotor by constructing the core part interposed between adjacent magnets of each pole of the rotor wider than the opening of slot. SOLUTION: At each pole of a rotor of four pole structure, a core part 12a forming the passage of q-axis flux is interposed between a shaft side magnet 3a and a counter-shaft side magnet 3b. The width W1 at the core part 12a between magnets in same pole is set wider than the width N2 of a slot opening 9a interposed between the tip parts at the tooth part 7 of a stator core 6a. Since the core part 12a between magnets is shifted to the rotational direction with respect to the tooth part, the rotor generates reluctance torque reversely to the rotational direction through action of magnetic attraction caused by the flux. But since the core part 12a is wide, the reluctance torque in the reverse direction is reduced and eventually canceled by the reluctance torque in the rotational direction.

Abstract: PURPOSE:To improve the resolution of an image by controlling electron beams of an in-line type electron gun with a dynamic converging means arranged at the upper and the lower sides of the electron beams of both sides respectively against the misconvergence resulting from the use of a static converging means only. CONSTITUTION:Electron beams 25-B, 25-G, 25-R from an in-line type electron gun can be converged on a picture screen with a static converging means, e.g. displacement of attaching central axis to each other, but it is difficult to converge the beams on the side portion and the central portion of the screen simultaneously. By correcting the misconvergence resulting from the use of the static converging means only with a dynamic converging means the resolution of the image can be improved. The dynamic converging means is provided in a pair on the outside of the neck portion of the picture tube where the electron gun is arranged, and constructed with magnetic elements 26 arranged horizontally at the upper and the lower sides of the both outside electron guns and magnetic field correcting elements 28 arranged close to the said elements 26 so as to couple magnetically. By a current synchronized to the current in the deflection coil, correction magnetic fields 27 of opposite direction to each other are generated between the said elements 26 respectively, so that the misconvergence can be corrected.

IPC: H04N5/335
Filed: 1983-07-15
Abstract: PURPOSE:To improve the transfer efficiency by providing the 2nd gate storing only a bias charge in a solid-state image pickup element. CONSTITUTION:The transfer until t=t0, t1 and t2 is the same as a conventional example. A channel potential 58 of a TG1 gate 50 is increased a little at t=t3 (d), and a channel potential 59 of a TC gate 51 is decreased at t=t4 and a bias electric charge Qp 28 is injected to a vertical transmission line 5 (e). A voltage is applied again to the TC gate 51 at t=t5 as it is so as to form a potential well (f), and a voltage is impressed to a TG2 gate 52 at t=t6 (g). Thus, a signal charge Qs and the bias charge Qp fill up the potential well formed by the TC gate 51 at first and then the overflowed charge is transferred to a potential 26 formed by a transfer gate 7 of a charge coupling type horizontal shift register 7 (h). The overflowed charge is the signal electric charge.

Title: Feeder structure of antenna
Inventor: HACHITSUKA HIROYUKI
IPC: H01Q19/13
Filed: 1982-07-26
Abstract: PURPOSE:To facilitate an easy mass production for the feeder structure of an antenna, by forming a bent rectangular waveguide by covering the groove part of a metallic plate formed with press working with its both open ends by another flat metal. CONSTITUTION:A metallic plate 1 is formed from a sheet of metallic plate with press working. The plate 1 forms three faces excepting a face formed with a metallic plate 3 among four faces forming the contour of a feeder, i.e. the three faces of a feeder including a primary radiator 5. Then a flange part 2 is fixed to the plate 3 with spot welding, a conductive adhesive, soldering, etc. The sectional form of the radiator 5 must be enlarged toward the radiating port of radio waves since the radiator 5 has a horn shape. Therefore it is required to fold the plate 3. Furthermore it is possible to form the plate 3 with a wire net having meshes suficiently smaller than 1/4 wavelength of a using radio wave. Thus, a feeder structure which facilitate an easy mass production is obtained.

Title: Drive circuit for light emitting diode
Inventor: KUROBA MASAYUKI
IPC: H01L33/00
Filed: 1982-07-26
Abstract: PURPOSE:To enable to obtain constant visual recognizability regardless of brightness of the surroundings by a method wherein a photo transistor and a visible light emitting diode are connected in series. CONSTITUTION:The circuit is formed in a structure wherein a power source 1, a protection resistor 2, the photo transistor 3, and the visible light emitting diode 4 are connected in series. When the voltage of the power source 1 is kept adjusted so that an appropriate fixed current flows in case of surroundings in normal brightness, the photocurrent flowing to the photo transistor 3 increases in proportion to the brightness in case of surroundings brighter than normal brightness, and thereby the current flowing to the visible light emitting diode 4 increases, then it shines brightly. In case of surroundings darker than normal brightness, since the photo current in proportion to the decrease of surrounding light flows to the photo transistor 3, the current flowing to the visible light emitting diode 4 decreases, and accordingly it shines darkly. The use of a light emitting diode which increases brightness in proportion to current enables the brightness of the visible light emitting diode 4 to vary in proportion to the brightness of the surroundings, resulting in constant visual recognizability to the surrounding brightness.

Abstract: PURPOSE: To prevent flour plugs from shown through by high pressure air and assure positive and perfect maintenance of plug formation during the plug-conveyance of flour material with low speed and high density, by installing a special nozzle to the plug forming pipe.  
     CONSTITUTION: A nozzle 15 attached to a plug forming pipe 6 has a fan h shaped opening 17 with an anticipated angle α at the lower position of a circular component 16. This opening 17 formed at the lower semicircle of the plug forming pipe 6 or the conveyor pipe 7 and has an angle of opening α, 90W180°. From this opening 17 high pressure air is injected intermittently with a fixed interval and for a fixed time period and to a diagonal direction as indicated by an arrow 23 with respect to the direction of flow of the flour material 22. Thus, the high pressure air interrupts the flow of flour material, alternatively forming a plug 24 and an air cushion 25.
