  • Patent number: 10443746
    Abstract: A main spool (24) has a throttle passage (30) that, when the main spool (24) moves to an axial other side against a first return spring (27) in a main spool insertion hole (13), communicates a pilot pressure chamber (25) with a first tank port (15) and limits a flow amount of hydraulic oil to be discharged to the first tank port (15) from the pilot pressure chamber (25). When the main spool (24) moves to the axial other side along the main spool insertion hole (13), the throttle passage (30) communicates the pilot pressure chamber (25) with the first tank port (15) before a state where a first pump port (17) is communicated with an output port (16) and a state where the output port (16) is blocked from the first tank port (15).

  • Patent number: 9546408
    Abstract: A method for quenching a steel pipe by water cooling from an outer surface thereof, where pipe end portions are not subjected to water cooling, and at least part of a main body other than the pipe end portions is subjected to water cooling. A region(s) that is not subjected to direct water cooling over an entire circumference thereof can be along an axial direction at least in part of the main body other than the pipe end portions. The start and stop of water cooling can be intermittent at least in part of the quenching. During the water cooling of the pipe outer surface, an intensified water cooling can be performed in a temperature range in which the pipe outer surface temperature is higher than Ms point. Thereafter, the cooling can be switched to moderate cooling so that the outer surface is cooled down to Ms point or lower.

  • Patent number: 8447167
    Abstract: A recording/reproduction device is provided wherein service content having interactivity can be restored even when recorded. In recording mode, a transport stream from a receiving device 34 is received and a conversion device 36 converts this to a packet-multiplexed stream in a condition suitable for recording, which is then output as a converted stream. The conversion device 36 selects packets relating to a desired service from the transport stream and, of these packets, selects only packets needed for reproduction and uses these to generate a converted stream. A recording device 38 records this converted stream on a recording medium 44. In reproduction mode, the converted stream from recording medium 44 is read by means of a reading device 42 and supplied to a restoration device 40. Restoration device 40, in accordance with the content of this converted stream, restores and outputs a service content signal (for example a composite signal such as NTSC).
