  • Publication number: 20120314420
    Abstract: A lighting apparatus includes a light source module, a heat sink holding the light source module and a light-permeable cover mounted to the heat sink and covering the light source module. The cover is adhered to the heat sink by an adhesive agent applied with a gap formed on at least one part between the cover and the heat sink. The inside and outside of the lighting apparatus can be communicated to each other due to the gap. Since the inside and outside of the lighting apparatus are communicated to each other, the problems of temperature difference and pressure difference between inside and outside of the lighting apparatus can be suppressed so that the occurrence of defects because of condensation and the like can be prevented.

  • Publication number: 20120293961
    Abstract: A lighting apparatus includes a light source, a power supply circuit supplying power to the light source, a heat radiating section made of electrical insulating material and radiating heat from the power supply circuit to outside air, and a heat conducting section conducting heat from the power supply circuit to the heat radiating section, and the heat radiating section and the heat conducting section are thermally connected. A weight reduction of the lighting apparatus is realized and a heat conduction from the heat conducting section to the heat radiating section is improved.

  • Publication number: 20120293057
    Abstract: The lighting apparatus according to the present invention includes a thermal source such as a light source or a power supply unit and a heat releasing portion for releasing heat from the thermal source, and further includes the first heat radiation film formed by applying a coating material containing a heat radiating material on the surface of the heat releasing portion and curing the material. Since the first heat radiation film is formed by curing the material containing a heat radiating material, heat emittance by infrared is improved compared to the case with a heat radiation film formed by anode oxide coating (alumite treatment), thereby enhancing the heat releasing performance while maintaining the heat releasing performance by heat radiation for a long period of time because of the high resistance to damages.

  • Publication number: 20120236573
    Abstract: A lighting apparatus includes LEDs and a light-permeable cover passing the light emitted from the LEDs and an anti-scattering film is arranged on the cover for preventing the scattering of fragments when the cover fractures. The anti-scattering film contains a dispersing agent for dispersing light. Since the anti-scattering film containing a dispersing agent is arranged on the cover, when the lighting apparatus is damaged by falling, the scattering of fragments of the cover is preventable, and the glare can be reduced because the light emitted from the LEDs are dispersed through the dispersing agent contained in the anti-scattering film. Since the anti-scattering film containing the dispersing agent is arranged on the cover, the deterioration of luminance flux is preventable as compared to a case of arranging on the cover a member for anti-scattering and a member for reducing glare separately.

  • Patent number: 4621178
    Abstract: There is disclosed an electrical signal input device suitable for use in a microwave oven or other household appliance for introducing a setting into those appliances through a simple one-touch actuation. The input device is of the membrane type which includes an actuator member composed of a generally flat plate having a plurality of elongated actuator sections on a surface thereof and carrying a plurality of first electrodes disposed wholly through an opposite surface thereof and facing against the plurality of the actuator sections, a substrate disposed in conjunction with the actuator member and having a plurality of second electrodes each corresponding to one of the first electrodes. The first and second electrodes are brought into electrical contact when the corresponding one of the actuator sections is depressed and becomes bent. It is sensed as to where the first and second electrodes are in electric contact along the length of the actuator sections.

  • Patent number: 4591681
    Abstract: A fluorescent display tube power supply device of a microwave oven provides a stable power source for the microcomputer by rectifying the output of the first secondary coil of the commercial AC power transformer, followed by rectifying a half wave of the second secondary coil of the same AC power transformer before feeding one-half cycle of the commercial AC current to the heater of the fluorescent display tube. The power supply uses a rectifying circuit for generating the double voltage for the second secondary coil, the double voltage being mixed in the direction in which it becomes lower than the stable voltage of the microcomputer, thus generating the display erase potential VP. As a result, luminance can be held constant respective display positions without causing the voltage of the display tube to vary throughout the ON-OFF operations of the heating power source, thus eventually achieving a highly satisfactory display effect.

  • Patent number: 4567575
    Abstract: An interface circuit is disposed between an NMOS random access memory and a PMOS central processor unit in order to ensure accurate data transfer therebetween. The interface circuit includes a pull-up system for pulling up a signal transmission line to a desired voltage level. The pull-up system is energized when the data signal is transferred from the NMOS random access memory into the PMOS central processor unit. The pull-up operation is not conducted when the data signal is transferred from the PMOS central processor unit into the NMOS random access memory.

  • Patent number: 4399524
    Abstract: A memory protection system includes an auxiliary power supply source for maintaining information stored in a random access memory when the main power supply is terminated. When the main power supply voltage level becomes lower than a preselected level, a detection unit develops a control signal for applying a disabling signal to a chip selection terminal included in the random access memory, whereby a load such as a central processor unit connected to the random access memory is electrically disconnected from the random access memory to minimize the power dissipation.
