  • Patent number: 6518958
    Abstract: In an electronic apparatus having a membrane switch and a touch panel switch at its entirety section, the touch panel switch is elastic and is laid over the membrane switch. The two-layered structure provides users with two operations: a “finger-sliding” operation and a “finger-depressing operation.” When a user slides a finger on the surface of the touch panel switch, the sliding force activates the touch panel switch. The “finger-sliding” is used for selecting a desired item. On the other hand, when the user presses down on the surface of the touch panel switch, the depression force through the touch panel switch activates the underlying membrane switch. The “finger-depressing” is used for numeric or symbolic information entry. It is thus possible to realize an electronic apparatus offering an excellent compromise between ease of operation and a wide display section.

  • Publication number: 20030027518
    Abstract: A simply structured remote control transceiver that stores various data supplied is disclosed. A data communication system employing the same transceiver is also disclosed. The remote control transceiver includes a signal transceiver, a controller, an operating section, a memory and a display. The signal transceiver transmits/receives radio wave or an infrared signal to/from a television receiving apparatus (TVRA). The controller is coupled with a signal transceiver, an operating section, a memory and a display. The memory stores data sent from the TVRA via the signal transceiver. Responsive to an operation through the operating section, the display displays data read out from the memory. The data communication system includes this remote control transceiver, the TVRA and a base station that handles data.

  • Patent number: 6504269
    Abstract: A touch type input device is used for various forms of control. A primary side line is connected to a power source, and a secondary side circuit ground through a power transformer are connected by an impedance element. Flat electrodes to be touched by a finger are formed on one side of an insulating base material, and are connected to a ground current detection circuit through a high resistor and a low pass filter. A control circuit for converting the output of the ground current detection circuit into a control signal for an electronic appliance, and a display unit are provided. Therefore, an input device having plural touch switches disposed on a base material in a free shape and layout can be obtained.

  • Patent number: 5539477
    Abstract: A signal transmitter and receiver (or a combination thereof) incorporated for example in audio and video apparatus such as a TV and a video-deck, comprises a synchronizing signal separator separating a synchronizing signal from video-signal, a monostable circuit of which period recovering its stable state, or unstable period, after an input of triggering signal, is longer than the period of synchronizing signal separated by the synchronizing signal separator, and a dc-power supply on-off controller controlling the on-off of dc-power supply according to the output of the monostable circuit. The dc-power supply on-off controller limits the supply of dc-power to a minimal number of circuits except during signal processing.

  • Patent number: 5273914
    Abstract: An ion implantation stopper is formed on a gate electrode extending on a substrate. When ions are implanted into the substrate to form an LDD layer or source and drain regions in the substrate, the stopper functions to prevent the gate electrode from being exposed to ion implantation. The prevention of the exposure of the gate electrode to the ion implantation ensures the prevention of channeling in the gate electrode. The invention includes forming a first protective film on the gate of an NMOS, implanting to form LDD region for the NMOS, implanting to form source and drain regions of a PMOS, forming a second protective film on the gate of the NMOS, implanting to form source and drain regions of the NMOS, the first and second protective films prevent the gate electrode of the NMOS from being exposed to ion implantation during the respective implanting steps so that channeling is prevented from occurring in the gate electrode of the NMOS.
