  • Patent number: 9695332
    Abstract: A release film for producing a green sheet of the present invention includes a base material and a release agent layer provided at a side of a first surface of the base material. The release agent layer includes an ultraviolet curable compound (A) having three or more reactive groups selected from the group consisting of a (meth)acryloyl group, an alkenyl group and a maleimide group in one molecule thereof, a polyorganosiloxane (B) and an ?-aminoalkylphenone based photopolymerization initiator (C). An arithmetic average roughness Ra1 of an outer surface of the release agent layer may be different than an arithmetic average roughness Ra2 of a second surface of the base material. According to the present invention, it is possible to prevent pinholes and variation in partially thickness from occurring to the green sheet.

  • Publication number: 20140349811
    Abstract: A vehicle driving system in which a clutch is disposed between an engine output member and an automatic transmission and the clutch is used as a start clutch that is slip-controlled when a vehicle starts. When a lubricant relay valve is switched to the communicating position, oil from the pressure-regulating oil passage is supplied to the clutch via the input port, the output port, and the clutch lubricant passage. When the lubricant relay valve is switched to the cutoff position, the oil from the pressure-regulating oil passage is supplied to the clutch via the orifice and the clutch lubricant passage, the feedback pressure of the feedback port is increased, the communication rate between the pressure-regulating port and the back-pressure port is increased, and the amount of lubricant supplied from the back-pressure oil passage to the lubrication portion of the automatic transmission is increased.
