Title: Copying machine
Inventor: YOSHIURA SHOICHIRO
IPC: G03G15/043
Filed: 1987-07-25
Abstract: PURPOSE:To prevent mistaken copying by resetting an exposure mode at an automatic exposure mode or a standard manual exposure mode when operation is switched to a 2nd copying action from a 1st one. CONSTITUTION:A ROM 2 storing control programs, etc., and a RAM 3 storing transfer, exposure modes are connected to a CPU 1, while a copying process part 8 handling both original exposure and copying process and a sheet conveying part 9 controlling the convey of sheets are connected to an interface 5. When in a synthetic copying mode, for instance a developing tank is selected and set to the photosensitive drum, 'good or not' of the setting is judged. If it is normal, the exposure mode is set at the automatic exposure mode so that exposure errors will not occur in the next copying work. When an original is judged to be replaced, the mode is set at the automatic exposure mode so that exposure errors caused by a density difference between the current and previous originals can be eliminated. Thus copying errors can be eliminated.

IPC: H03K4/06
Filed: 1996-07-16
Abstract: PROBLEM TO BE SOLVED: To set output voltage to be constant and to always maintain change width to be constant even if deflection frequency changes by changing rise voltage per sample pulse in accordance with the period of a sawtooth wave signal. SOLUTION: Constant voltage is supplied to the input terminal 13 of a sample/hold circuit 1 from a constant voltage input circuit 3 and the sample pulse SP is supplied to a logic input terminal 15. When it comes to a sample period, the holding capacitor 20 of an integrated circuit for sample/hold 6 is charged by input voltage. When it becomes a holding period, SP is phase-inverted by an invertor 31, output voltage is supplied to an integrated circuit for operation circuit 23 and the voltage of an output terminal 26 rises. When a switching element 21 is turned on by a reset pulse RP from outside, the charge of the capacitor 20 is discharged and the voltage of the integrated circuit 23 becomes zero. Thus, the sawtooth wave signal of a prescribed period is outputted whenever RP is supplied.

IPC: H02J7/14
Filed: 1999-07-01
Abstract: PROBLEM TO BE SOLVED: To operate a charger always in the state of its high battery-charging efficiency, by performing on/off control of a FET in the vicinity of the zero- phase of its AC input voltage through the output voltage of a comparison circuit. SOLUTION: A three-phase AC generator generates three-phase AC outputs, and an single phase voltage Va of the generated three-phase AC outputs is inputted to a comparator COMP1 to send out an output determining signal JS of its determining result. The determining signal JS is inputted to a comparator COMP2, and it is compared with a reference signal Vc to send out the determining signal JS in its low output term as the gate signal of a FET. Further, at the instant when the determining signal JS is changed from a high level to a low level at a predetermined time, a transistor Q1 is brought into an on-state in the vicinity of the zero-phase of an AC input voltage to turn on a thyristor T1 by giving to it a gate signal. Thereby, a charger can be always operated in the state of its high battery-charging efficiency.

Title: Hydraulic controlling method for belt-type non-stage transmission
Inventor: SAWADA DAISAKU
IPC: F16H61/06
Filed: 1984-09-06
Abstract: PURPOSE:To moderate force by which a pulley keeps a transmission belt by varying oil pressure compensation value which corresponds to a thrust produced at a hydraulic cylinder from a value used when revolutional speed of the hydraulic cylinder is not varied yet to another value used when revolutional speed thereof is varied, in accordance with the specified delay characteristics. CONSTITUTION:Reference oil pressure is determined on the basis of both factors of transmission torque and speed ratio and oil pressure compensation value corresponding to a thrust which is produced at a hydraulic cylinder 22 by the effect of a centrifugal force is also determined in accordance with an actual revolutional speed. A control oil pressure is then derived by subtracting the compensated oil pressure is then fed to said hydraulic cylinder 22, whereby adjusting a holding pressure of variable pullies 24 and 26 to a demanded and sufficient value with respect to a transmission belt 36. For such adjustment, said oil pressure compensation value is varied from a value used when said hydraulic cyulinder 22 is not changed yet in revolutional speed to another used after revolutional speed thereof is varied in accordance with the specified delay characteristics. By the operation, excessively tight or loose holding of the variable pullies 24 and 26 with respect to the transmission belt 36 may then be dissipated even if the hydraulic cylinder 22 is in such transient state that revolutional speed thereof is changed.

Filed: 1983-10-06
Abstract: PURPOSE:To receive one command and plural frames by allowing a communication program on a CPU to discriminate a section of each frame based on a data address issued together with one command and added information. CONSTITUTION:When a start I/O is issued from the CPU4 to the communication controller 1, the controller 1 fetches a command from an address of a main storage device 5 and stores it to a memory area 6.

Each data length in a frame received continuously is counted by the controller 1 and the data length is stored in a memory area 8. The data is stored in the device 5 as the additional information representing the section of the frame from the head address stored in the area 7 and the data length stored in the area 8. Thus, the controller 1 receives plural consecutive frames from a terminal device 2 by using one command.
