  • Publication number: 20130074719
    Abstract: The present invention is a method for producing a sleeve printing plate which is attached to a cylinder of a printing apparatus, including a notch forming step in which, a laser beam is irradiated to the sleeve element assembly while rotating a sleeve element assembly attached to a rotating drum together with the rotating drum, thereby forming a positioning notch which is engaged with a guide pin erected on the cylinder and an image pattern forming step in which the laser beam is irradiated to the sleeve element assembly while rotating the sleeve element assembly attached to the same rotating drum as that of the notch forming step together with the rotating drum, thereby forming an image pattern to be printed on a work piece.

  • Patent number: 5421025
    Abstract: Supplied with first and second signals from first and second control units (19, 29), first and second reading units (17, 27).read first and second readout ATM signals from first and second primary memory units (15, 25) which memorize an ATM signal (11). The second control unit produces the second-reading signal when a predetermined interval lapses after supplied with a first reading start signal from the first control unit. A first processing unit (21) processes the first readout ATM signal into a first STM signal and a first processed content signal. A second processing unit (31) processes, in response to the first processed content signal, the second readout ATM signal into a second STM signal. An output reading unit (35) read first and second output STM signals at the same time from first and second secondary memory units (23, 33) which memorize the first and the second readout STM signals.

  • Patent number: 4606050
    Abstract: What is disclosed is a system for recovering encoded data from a transmitted signal. A clock regenerating circuit regenerates a clock signal from the data bits encoded in the signal. The regenerated clock signal is used to synchronize an up/down with each individual data bit. When a data bit is at a logic "H", the counter counts from a predetermined value in an upward direction and when the data bit is at a logic "L", the counter counts in a downward direction from a predetermined value. The count after each bit-time is used to provide a signal representative of the logic state of that data bit. Accordingly, a reproduced data signal can be accurately obtained.

  • Patent number: 4509201
    Abstract: Two limit voltages are established for a wireless telephone apparatus. If the power supply voltage exceeds the first limit voltage, the transmitter of the wireless telephone apparatus is prevented from radiating signals. At the same time, the central processing unit of the wireless telephone apparatus shelters, in a dedicated shelter register, the control data necessary to carry on communication once power is restored, and an inhibit circuit prevents the central processing unit from writing into the read-write memory. If the power supply voltage exceeds the second limit voltage, the central processing unit is disabled from exercising control of the apparatus. When the power supply voltage returns within the second limit voltage, the central processing unit is enabled to exercise control over the apparatus. When the power supply voltage returns within the first limit voltage, the transmitter is enabled to radiate signals and the central processing unit reestablishes communication using the sheltered data.
