  • Patent number: 8346061
    Abstract: The digital signal recording/reproducing apparatus inputs a digital signal having a control flag as to a temporary copy permission, and records the digital signal temporarily into a recording medium in accordance with conditions in the control flag, then reproducing the digital signal temporarily from the recording medium in accordance with the conditions in the control flag. The recording/reproducing of the temporary copy is permitted, depending on the following conditions: The recording medium's type, the reproducing point-in-time, the reproducing time-period, and the reproducing frequency. With this method employed, even in a program permitting no recording, the temporary recording/reproducing is permitted under a condition of being limited to the time-shift recording on the receiving side.

  • Patent number: 5249906
    Abstract: Pin head mounting members are rotatably mounted on a horizontal spindle above a table which horizontally supports a holding, plate holding chip type electronic components. The spindle is vertically movable by a vertical cylinder. Each pin head mounting member is shaped as a rectangular sleeve. A mounting surface is formed on each side portion of the pin head mounting member. A pin head each having a number of press pin is detachably mounted on each of the mounting surfaces A locking pin is provided on an upper end portion of the spindle for locking the pin head mounting members every 90.degree.. Thus, it is possible to efficiently replace press pins in response to a type change of chip type electronic components, as well as to quickly exchange a broken press pin.

  • Patent number: 5244073
    Abstract: A press machine comprises a holding plate provided with a number of receiving holes at constant arrangement pitches and a pin head having a number of press pins at the same arrangement pitches as the receiving holes. A portion provided with the receiving holes is in the form of a square, while a portion provided with the press pins is also in the form of a square, which has a width identical to that of the portion provided with the receiving holes and a depth half that of the portion provided with the receiving holes. The holding plate is placed on a movable table, which in turn is moved to a first working position to insert a first group of chip type electronic components into the receiving holes provided in a first half region of the holding plate by the press pins, and then moved to a second working position to press a second group of chip type electronic components into the receiving holes provided in a second half region of the holding plate by the press pins.
