Title: Current source cell device
Inventor: DAE BON BIIKU
IPC: H03K17/687
Filed: 1997-11-06
Abstract: PROBLEM TO BE SOLVED: To offset noise generated from a current source in a high frequency operation by alternately arranging a first current source cell for supplying the current of a current source by the signals of a high level and a second current source cell for supplying the current of the current source by the signals of a low level. SOLUTION: When a second bias voltage D is at the high level, in the first current source cells Ca1-Can, PMOS transistors Q2' and Q3' are respectively turned OFF and turned ON and the current is supplied to a common node Vy. At the time, the inverted voltage DB of the second bias voltage D is at the low level, and in the second current source cells Cb1-Cbn, NMOS transistors Q2" and Q3" are respectively turned OFF and turned ON and the current is supplied to the common node Vy. In the first current source cells Ca1-Can and the second current source cells Cb1-Cbn, since enabling is performed by the voltages of the mutually opposite levels, the noise is offset.

Title: Bus abnormality detecting circuit
Inventor: SUZUKI TOSHIO
IPC: G06F13/00
Filed: 1988-12-01
Abstract: PURPOSE:To accurately detect the abnormal state of a bus by using a means which detects the bus abnormality when the measured time needed for acquisition of a bus reaches a prescribed level. CONSTITUTION:A bus request signal 2 that acquired the bus using right starts the execution of an I/O access instruction 12. In this case, however, an answer signal 35 is not received to the instruction 12 from a control package set on a bus serving as an instruction executing object. Then the measured time when the output of a 4-input NAND gate 20 of an instruction executing timer counter 25, i.e. The instruction 12 is kept valid exceeds the time TBTO which is previously set at the counter 25. Thus the BT1, i.e. the output T1 of an instruction executing time abnormality FF 26 becomes valid to show that no instruction answer signal is not received even after the instruction 12 started by the signal 2 exceeds the time BTO. At the same time, the signal 35 which completes the instruction 12 is sent to a 3-state driver 28 via an enable signal received from an FF 27 as soon as the BT1 becomes valid.

Title: Opening/closing mechanism of upper frame in image forming device
Inventor: EGI MAKOTO
IPC: B41J29/13
Filed: 1996-11-15
Abstract: PROBLEM TO BE SOLVED: To precisely control the speed of closing an upper frame by providing the variable braking force imparting mechanism capable of increasing the braking force corresponding to the progress of the closing operation. SOLUTION: In this device, on starting the closing operation of the upper frame 12 by applying the lock releasing force to the upper frame 12, the top end 301 of a lever 302 slides on a stepped part 122b of a turning transmission gear 122 in company with the turning work of the turning transmission gear 122. When the closing operation of the upper frame 12 is progressed and the top end 301 of the lever 302 is allowed to pass a position AP2, the braking force applied corresponding to the closing operation of the upper frame 12 is increased, in company with the closing operation. Moreover, when the operation of closing the upper frame 12 progresses and becomes to just before the completion of closing, the range from a rotary shaft 121 to the stepped part 122b rapidly becomes longer, therefore the braking force by a coil spring 305 rapidly becomes weaker.  In such a manner, by making the braking force by the coil spring 305 weakened in the finally closing stage, an operator can close the upper unit without applying the force stronger than needed.
