  • Patent number: 6558058
    Abstract: A coating tool has a printer head capable of securing a smooth traveling of a transfer tape having a correcting paint or a paste applied thereto by preventing adhesion of the transfer tape to the printer head thereby securely transferring and coating the correcting paint or paste to the surface of a target object.
    Type: Grant

  • Patent number: 6435248
    Abstract: An applicator for transferring a transfer material like a correction paint or paste from a transfer tape to a substate surface comprises an elastic tongue piece 8 having a tip 8′ as part of a transfer head 7. The tip 8′ has a curved discharge or downstream surface 10 whose radius of curvature is between 0.75 and 1.5 mm and a curved transfer or upstream surface 11 whose radius of curvature is between 1.5 and 2.5 mm. Both of these curved surfaces 10 and 11 are connected with each other to provide a large transferring surface 12 which ensures that the transfer material can properly be transferred onto a substrate surface over a wide range and that the transfer tape can pass the tip in a smooth and continuous manner.

  • Patent number: 6379461
    Abstract: A coating tool is provided which is adapted to transfer a paste or a correcting paint from a transfer tape to a target object. The coating tool comprises a main body housing therein a supply reel and a supply reel gear, supported by a first shaft, and a take-up reel and a take-up reel gear, supported by a second shaft. According to one embodiment of the present invention the coating tool includes an annular rib formed on the cylindrical portion of the supply reel gear and an elastic edging strip, for holding and engaging the supply reel gear, formed on the inner wall surface of the engagement hole of the supply reel and positioned between the annular rib and the supply reel gear. Accordingly, the delivery and taking-up of the transfer tape can be performed smoothly and securely without the thermal deformation of the elastic edging strip.

  • Patent number: 5801995
    Abstract: An option setting circuit includes a set circuit with respect to which an option is set, a non-volatile memory for storing an option data for setting the set circuit which memory is provided exclusively for the set circuit, and a latch circuit which latches an option data provided from the non-volatile memory and provides the data to the set circuit.

  • Patent number: 5438279
    Abstract: In a microcomputer, a circuit is provided which performs the option setting of the condition of an I/O port. The option setting is repeatedly performed while the microcomputer is operating. As a result, even if the option setting is changed to an incorrect setting due to noise from external sources, the incorrect option setting is immediately returned to the correct setting. Moreover, the option setting is never reset at the time of resetting other than the resetting performed at the time of the turning on of the power.

  • Patent number: 5396639
    Abstract: A one-chip microcomputer according to the present invention is provided with an initial reset circuit for producing a first initial reset signal having a first reset period and a second initial reset signal having a second reset period which is longer than the first reset period, an access circuit for gaining access to an address in a nonvolatile memory such as a built-in ROM to read data therefrom, and I/O buffer circuits. A storage circuit and an I/O buffer connected to a programmable I/O terminal are provided in the I/O buffer circuit and a function of the I/O terminal with options is selected in conformity with the data set in the storage circuit. The data stored at a predetermined address in the nonvolatile memory is transferred to the storage circuit by operating the access circuit until the termination of the reset period of the second initial reset signal after the termination of the first reset period of the first initial reset signal.

  • Patent number: 5208492
    Abstract: The improved CMOS output circuit has an enhancement-type PMOS and an enhancement-type NMOS connected in order between a power supply line and a reference potential line and that has the junction between the PMOS and the NMOS connected to an output terminal. The PMOS is such that a P-type region is provided in the back gate region to form a diode, with the back gate region being connected to the power supply line via the diode. A switch circuit is inserted between the gate of this PMOS and said junction or the output terminal. When a voltage higher than the voltage on the power supply line is applied to the output terminal, the applied voltage will turn on the switch circuit.
