Patent number: 6836269Abstract: A precharge control circuit constituted by (1) a latch circuit mounted in a precharge circuit and (2) a level shifter circuit of a current drive type controlled through an output of the latch circuit is included. The precharge control circuit changes the latch circuit to an active state to cause the level shifter circuit of a current drive type to operate only during a precharge period and also during immediately preceding and succeeding periods, and outside these periods, changes the latch circuit in a non-active state and the level shifter circuit of a current drive type in an operating state to save power consumption in the level shifter circuit. This enables a low-power-consuming precharge circuit, as well as a low-power-consuming image display device with a high quality display capability, to be offered.Type: GrantFiled: February 28, 2001Date of Patent: December 28, 2004Assignee: Sharp Kabushiki KaishaInventors: Kazuhiro Maeda, Hajime Washio, Yasushi Kubota, Yasuyoshi Kaise, Michael James Brownlow, Graham Andrew Cairns

Patent number: 6698950Abstract: A printer implements printing(printer jobs) of the data received from personal computers and printing(copier jobs) of the data scanned through a copier functional device. When a user approaches the printer, a user identifying portion identifies the ID number(user name) of this user. If a printer job of this user name has been registered in the management memory of the printer, it is determined whether the printer job of this user name is ‘allowed’ to make an interrupt and whether the priority of this printer job is higher than that of the copier job. After confirmation of these facts, the printer job of this user name is started by making an interrupt.Type: GrantFiled: June 20, 2001Date of Patent: March 2, 2004Assignee: Sharp Kabushiki KaishaInventor: Wataru Nishii

Patent number: 6697038Abstract: A plurality of signal input-output sections are connected with each other in a cascade manner. In each signal input-output section, an input latch circuit divides a data signal into 2 channels in accordance with the first clock signal, and an output latch circuit returns the data signal that has been divided into 2 channels to 1 channel in accordance with the second clock signal so as to be outputted to the signal input-output section of the next stage. The inputted first basic clock is outputted to the signal input-output section of the next stage as the second basic clock, and the inputted second basic clock is outputted to the signal input-output section of the next stage as the first basic clock. This allows to ensure the data sampling margin even when the data signal should be transferred at a faster speed, and also allows to suppress the problem of the EMI.Type: GrantFiled: June 1, 2001Date of Patent: February 24, 2004Assignee: Sharp Kabushiki KaishaInventor: Hideki Morii
