  • Patent number: 6556275
    Abstract: An optical printer including a fluorescent light-emitting tube equipped with an anode in a form of dot and a rotatable rotating filter part equipped with filters R, G, B. A film is moved relative to the optical printer set at a given position. A controlling means rotates the rotating filter part, and, in synchronization with that, the fluorescent light-emitting tube is made to emit light by the image signal of every color of red, green and blue. The image can be formed by moving the film one time relative to irradiation with the light in a state of a dot transmitted selectively through each filter of red, green and blue. Since the head is fixed and the film is moved, room for the movement of the head which has been conventionally required is not required. Spatial room for the slide of the filter is not required differently from the slide-switching type-filter of the conventional art.

  • Patent number: 5943872
    Abstract: In an air conditioner, a supporting base having a plurality of bearing cylinder portions is attached to an outlet of a housing of the air conditioner. Each shaft of wind horizontally direction plates is located in the outlet of the housing and is disposed in the bearing cylinder portion through first and second bearing bushes. The first bearing bushes hold the wind horizontally direction plates in a cantilever manner. A heat insulation material is adhered onto the supporting base. The wind horizontally direction plates can be easily attached to the air outlet after the heat insulation material is installed, and the moisture condensation is prevented.

  • Patent number: 5589738
    Abstract: A field emission type display device capable of providing display with gradation and permitting the whole display device to be integrated with a display drive circuit section. Memory sections are arranged in correspondence to image cell sections, resulting in static display being accomplished. Also, Light emission of an anode is carried out depending on data held in the memory section, so that a luminous period is increased and adequate luminance is provided at a drive voltage substantially lower than that required for dynamic display. An FEC element is incorporated in each of the memory sections in correspondence to incorporation of an FEC element in each of the image cell sections, so that the image cell sections and memory sections may be concurrently manufactured during manufacturing of the FEC elements, to thereby significantly simplify manufacturing of display device.

  • Patent number: 4096559
    Abstract: A power supply circuit for a high voltage driven device, particularly a magnetron, is described. The power supply circuit comprises first and second switching elements, an inverter circuit including a commutating reactor connected in series with the first and second switching elements and a capacitor connected to a center tap of the commutating reactor, a transformer connected to an output of the inverter circuit, and a third switching element connected in parallel with a series circuit comprising the capacitor, the primary winding of the transformer and a portion of the commutating reactor. When the magnitude of a current flowing in the transformer exceeds a predetermined level, the third switching element is fired to establish a discharge loop for the capacitor through the series circuit whereby the amplitude of the current supplied to the transformer is limited below the predetermined level.

  • Patent number: 4039183
    Abstract: A device is provided for exercising and strengthening the human wrist, which comprises a concave trough with two parallel spaced members projecting from one end thereof and a grip rotatably mounted on the elongated member. Springs provide a force which rotates the grip away from the longitudinal axis of the concave trough. The device fits on the human forearm directly above the wrist and provides wrist strengthening exercises for the user by means of the grip being biased by the force of the springs against the flexing of the wrist.
