  • Patent number: 11914871
    Abstract: An electronic control device includes a nonvolatile memory having allocated two storage areas that are exclusively switchable between an active state and an inactive state, the two storage areas being set such that in a state in which a program is written in the storage area in the active state, a program is written for updating to the storage area in the inactive state in response to an instruction from an external device, followed by switching the storage area in the active state to the inactive state and switching the storage area in the inactive state to the active state. In the electronic control device, when the program written in the storage area in the active state differs from the program written in the storage area in the inactive state, the program written in the storage area switched to the active state is copied to the storage area in the inactive state.

  • Patent number: 10508214
    Abstract: The present invention relates to a polyester coating composition used for forming a coating film of a coated metal plate, a metal container, a metal closure, etc. The coating composition has a crosslinking agent and a curing catalyst incorporated into a mixed polyester resin comprising a mixture of a polyester resin (A) having an acid value of 2 to 50 mg KOH/g and a glass transition temperature (Tg) of 35 to 100° C. and a polyester resin (B) having an acid value of 0 to 50 mg KOH/g and a glass transition temperature (Tg) of ?20 to 25° C. Thus, a coating composition excellent in resistance to embrittlement over time, corrosion resistance, scrape resistance, retort resistance, and blocking resistance can be provided.

  • Patent number: 6715507
    Abstract: A vaporizer comprises disks each including an aperture at a central portion thereof. A hollow pipe having apertures for permitting radial outflow of a liquid extends through the aperture of each of the discs so as to form a stack of the discs. A resilient member applies a biasing force to the discs, and structure applies a force, via fluid control, against the biasing force to thereby remove the biasing force from the discs. Liquid in the hollow pipe is adapted to be delivered from the apertures to spaces between the discs and vaporized in the spaces between the discs.

  • Patent number: 6581625
    Abstract: The liquid supply system comprises a pump for delivering a liquid under high pressure and a vaporizer for vaporizing the liquid delivered from the pump. The liquid vaporized in the vaporizer is supplied to a reaction chamber. A pressure gage is provided in a passage extending from the pump to the vaporizer. A monitor device is provided so as to indicate a pressure, based on an output of the pressure gage.

  • Publication number: 20010017420
    Abstract: In an electronic component including: a sintered body with an internal electrode embedded; and an external electrode formed on the outer surface of this sintered body that is connected to the above internal electrode, a porous external electrode having numbers of pores is formed in the sintered body and thereafter the resin is impregnated through the pores. Thereby the pores of the external electrode are impregnated with a substance of the same sort as that of the buffer material as well as the buffer material interposes between the sintered body and the internal electrode.

  • Patent number: 6252481
    Abstract: Delamination in the conventional chip-type electronic part may create voids thereinside, allowing an internal electrode therein to vibrate in presence of external impacts or large electromagnetic forces caused by a high frequency current flowing inside the electrode, in such a way that fatigue may accumulate in the internal electrode, which eventually will results in the internal electrode being electrically disconnected. To solve this problem, a chip-type electronic part of the present invention includes synthetic resins impregnated into the voids to secure the internal electrode, wherein external electrodes of the chip-type electronic part are made of a conductive synthetic resin or a porous conductive material formed by sintering a conductive paste.

  • Patent number: 5741968
    Abstract: Elastic members are retained in respective recesses of open boxes. Heating (cooling) temperature sensing elements are held on the elastic member. A pipe which has already been laid is sandwiched between the open boxes such that the heating (cooling) temperature sensing elements join to desired positions, respectively, of the existing pipe. The pipe is subjected to a temperature change by the heating (cooling) temperature sensing elements, and hence the fluid therein is subjected to a temperature change, causing a temperature gradient to occur between the upper and lower streams of the fluid flow. The temperature gradient is detected by the heating (cooling) temperature sensing elements, and a flow rate of the fluid flowing through the pipe is obtained on the basis of the outputs of the sensing elements.
