Abstract: PURPOSE:To shorten a rise time in the case of switching a transfer current without causing cost inclease of a power source and making the power source larger even when contact electrostatic charging is used for transfer process in an image forming device such as an electrophotographic color copying machine or printer. CONSTITUTION:The output sides of positive and negative high voltage power sources E1 and E2 being output variable DC-DC converter are connected in series, and power is supplied to the load L of a transfer brush from one end of the power source. In such a case, output voltage and output current(load current) from the power sources E1 and E2 are detected and compared with a reference value from a microcomputer 21 by error amplifiers 13 and 14. Then, output from the amplifiers 13 and 14 is selected by analog switches Q1 and Q2. The output voltage and output current in specified timing are detected and stored in a memory in the microcomputer 21, then the stored value is switched to a reference value. By setting the intermediate value of the output level of the selected amplifier 13 or 14 as a threshold, the power sources E1 and E2 are selectively actuated to switch constant-voltage control and constant- current control of both polarities.

Title: Magnet speed change gear
Inventor: TOKUNO TOMOTOSHI
IPC: F16H49/00
Filed: 1990-11-20
Abstract: PURPOSE:To see that there is no fear of current leakage even if the line of magnetic force changes at high speed and that power conduction loss is zero by making large and small each roll a plastic electric insulator. CONSTITUTION:Since the large roll 3 with a large axis and the small roll 4 with a small axis are supported a small gap P apart, both rolls are each free in rotation. N and S poles of magnets 5 and 6 are buried outward at regular intervals in both roll faces. Since the magnets 5 and 6 puts out the lines of magnetic force in nonmagnetic plastic, the magnetic poles N and S of both rolls attract each other strongly, so if one roll rotates, the magnetic pole of the other roll conducts the rotation by the magnetic force so that the teeth of the gears may engage each other. For the conduction of the rotation, since the interval between both rolls is extremely small at approximately 1-2mm, the magnetic force working between them is strong, and the conductive torque is extraordinary great.

Inventor: NAKAMURA KATSUSHIGE
IPC: G02B21/24
Filed: 1987-12-16
Abstract: PURPOSE:To eliminate the contact replacement of operating tools by removing at least the forward end of an assistant scope and covering it with a free sterilization cover. CONSTITUTION:The sterilization cover 15 to cover the bottom 14 is slidably fitted to the top part of the assistant scope 12 through a slide rail 16.

Water flows into a water chamber 33 from an inflow port 34, and is introduced into a secondary water pressure chamber 19 from a primary water pressure chamber 18 and a water passing port 46 of a tubular valve body 40 through a gap part 17. Since, at this time, a disc 50 supported onto a diaphragm 60 is pressed to the downstream side (upwardly), the gap part 17 is contracted, and a constant quantity of water flows into the secondary water pressure chamber 19. At the same time, the water in the primary water pressure chamber 18 is introduced into an opening degree adjusting part 80 from an introducing passage 22. The opening degree of an opening degree adjusting port 88 is varied according to the extension force of a coil spring (temperature sensing member) 95, and the pressure difference between the water pressure chambers 18 and 19 is adjusted, and the water quantity corresponding to the temperature flows out. Therefore, the supply quantity characteristic for the water temperature can be set freely only by changing the opening degree characteristic of an opening degree adjusting valve 90. Further, the necessary quantity of parts can be reduced, and reliability is improved.

IPC: G06F3/041
Filed: 1995-12-06
Abstract: PROBLEM TO BE SOLVED: To accurately detect a pressed (touched) position with no influence of the temperature. SOLUTION: The touch panel controller consists of a horizontal resistance film 1 and a vertical resistance film 2 and detects the voltage at each end part of both films 1 and 2 in a non-touch state to store these detected voltage in a RAM 12.
