Title: Detecting circuit of phase difference between ac voltage and current
Inventor: SAITOU HIDE
IPC: G01R25/00
Filed: 1982-12-10
Abstract: PURPOSE:To detect the quantity of advance and lag in phase, by detecting a phase difference between AC voltage and current on a basis of a DC voltage level obtained by averaging and synthesizing the added value of advancing phase-side and lagging phase-side sample holding means in DC. CONSTITUTION:Respective zero crossing times of a voltage and a current are detected by a detected data operating circuit 10, polarity inverters NOTi, and NAND gates NANDi to generate prescribed logical conditions, and information concerning the time difference of zero crossing are sampled on a basis of the logical condition output by advancing phase-side sample holding circuits 20I and 20II, and output states are shifted periodically from each other by the phase difference of a half cycle, and lagging phase data are sampled similarly by lagging phase-side sample holding circuits 20III and 20IV. These outputs are added and are averaged in DC and are synthesized to attain the DC voltage level, and the phase difference between AC voltage and current is detected on a basis of this DC voltage level.

Title: Data transfer speed control system
Inventor: MATSUNAMI HIROYUKI
IPC: G06F13/42
Filed: 1990-08-17
Abstract: PURPOSE:To assure the coincidence of data transfer speeds between an input/ output processor and a peripheral processor by setting the information on the data transfer speed stored previously in a service processor as the data transfer speeds of the input/output processor and the peripheral processor themselves. CONSTITUTION:A data transfer speed control part 32 reads the data transfer speed set value (alphaMB/S) out of a data transfer speed control table 33 and transmits it to the interface control parts 12 and 22 of an input/output processor 11 and a peripheral processor 21 respectively. Both parts 12 and 22 receive the value (alphaMB/S) and set the information of this value to the data transfer speed tables 14 and 24 to control the data transmission/reception parts 13 and 23 respectively at a data transfer speed defined as alphaMB/S. Thus the data are transferred at the speed alphaMB/S in regard of the interface set between both processors 11 and 21.

Title: Method for controlling copying device
Inventor: SAKATA TOMOSHI
IPC: G03G15/00
Filed: 1988-09-02
Abstract: PURPOSE:To surely prevent collision between a lens system and mirror by a simple method by starting copying operations of an optical scanning exposure system after returning the lens system to the unmagnified position when the copying operations of the optical scanning exposure system is instructed while the lens system is at a variable power position. CONSTITUTION:When a copying device is started by turning on the power switch and copying operations are instructed by means of ten keys, whether or not a synchronous exposure system is selected is discriminated. In the case the system is selected, the copying operations of the system are carried out under the same condition. When the system is not selected, namely, an optical scanning exposure system is selected, the storing data of a memory 44 indicating the position of a lens system are confirmed whether or not the lens system is at an unmagnified position. When it is discriminated that the lens system is at the unmagnified position, the copying operations of the optical scanning exposure system are carried out under the same condition. However, when it is discriminated that the lens system is not at the unmagnified position, the copying operations are carried out after the lens system is moved to the unmagnified position by means of a lens drive motor 48. Therefore, collision between a mirror and the lens system can be surely prevented by a simple method.
