  • Patent number: 10309528
    Abstract: The present invention is configured such that: in a stopped state of an electric oil pump (M/O/P), control of the electric oil pump (M/O/P) is started such that, when a driver has the intention of demanding drive force, a discharge pressure takes on a target hydraulic pressure (PTh) determined in accordance with the demanded drive force from the driver; and a pressure regulation target value of a line pressure regulation valve (101) is set to a value that is higher than or equal to the target hydraulic pressure (PTh). Thus, it is possible to provide a vehicular hydraulic control device capable of suppressing hunting in line pressure (PL) when the line pressure (PL) is regulated so as to take on the target hydraulic pressure (PTh).

  • Patent number: 7397340
    Abstract: A load sensor includes a substrate, a glass layer provided on the substrate, a wiring provided on the glass layer, an adjusting layer provided on the glass layer, and a strain-sensitive resistor element provided on the adjusting layer and connected to the wiring. A thermal expansion coefficient of the adjusting layer is closer to that of the strain-sensitive resistor element than that of the glass layer. In this load sensor, a stress remaining inside the resistor element is reduced, and the change over time of the resistance of the element is accordingly suppressed. Therefore, a single kind of the resistor element can be formed on substrates having respective thermal expansion coefficients, shapes, and thicknesses, thereby providing various load sensors having respective specifications.

  • Patent number: 7097287
    Abstract: Here disclosed is an ink jet apparatus having an ink-circulating/dispersing function. The apparatus provides ink with dispersion as required, and circulates the ink through a tube to an ink-collecting tank. During this circulation, a required amount of the ink is fed to a printer head to form a predetermined pattern on a surface of a substrate. By virtue of the circulating/dispersing function, the apparatus can cope well with easy-to-aggregate ink having poor stability in terms of printing, thereby protecting a printer head or an ink-spouting section from clogging during ink jet printing. Such stabilized ink jet printing contributes to manufacturing highly reliable electronic components with an increased yield of products.

  • Patent number: 7043996
    Abstract: A strain sensor includes a metal plate, a first glass layer on the metal plate, a second glass layer provided on the first glass layer and having a color different from that of the first glass layer, an electrode on the second glass layer, a strain-sensitive resistor on the second glass layer, a circuit pattern on the second glass layer for connecting the electrode to the strain-sensitive resistor, and an overcoat glass layer for covering the strain-sensitive resistor and the circuit pattern. The strain sensor allows the layers to be identified while being manufactured, hence being controlled easily in its manufacturing processes.
