Title: Compound type magnetic head
Inventor: YOSHIDA MAKOTO
IPC: G11B5/265
Filed: 1995-03-09
Abstract: PURPOSE: To improve overwrite-characteristics and to reduce the number of parts and assembly man-hour by increasing the width of an erasure head as compared with before and adopting the erase-and-write system. CONSTITUTION: A single recording/reproducing head coil and a single erasure head oil are used and the erasure head consists of cores 11A and 11B and a coil assembly 11C, thus forming an erasure gap 11D. A recording/reproducing head consists of cores 12A and 12B and a coil assembly 12C, thus forming a recording/reproducing gap 12D. Then, the head width (not gap width) of the erasure head is wider than the head width of the recording/reproducing head and the erasure head is arranged so that it precedes the recording/reproducing head when a floppy disk rotates, thus enabling the erasure head to precede the recording/reproducing head, perform erasure operation over the entire width of a track, and to completely erasure past recording.

Title: Method and apparatus for maintaining given potential ratio when electrostatically charged photosensitive layer is exposed to light
Inventor: KURAUSU ROITAA
IPC: G03G15/00
Filed: 1985-03-14
Abstract: The light-sensitive layer of a printing plate is charged to a given surface potential which is measured by means of a stationary or moving potential detector. The potential ratio, which changes during the exposure, is continuously compared with a given set value, and the exposure is terminated when the changing potential ratio is in agreement with the given set value. The measurement of the surface potential and of the potential ratio is carried out in a bright area of the light-sensitive layer, which area is located outside the area of the latent electrostatic image. The potential detector may be connected via a signal converter and an amplifier to a microprocessor control which actuates a shutter via a digital output. In the microprocessor, a program for controlling a corona electrode and a developing electrode is stored, which program actuates the corona control and the developing electrode control via a digital/analog output and high-voltage amplifiers.

Title: Variable pressure control method for ink refilling
Inventor: MARK E YANG
IPC: B41J2/175
Filed: 1998-03-02
Abstract: PROBLEM TO BE SOLVED: To reduce a refilling time of ink to a printing cartridge mounted on a carriage, to ensure certainty of a volume of ink refilling, and to set a vacuum-pressure of the printing cartridge. SOLUTION: A height of each of ink storage tanks 80-86 for an ink cartridge outside a carriage is varied so that a quantity of refilled ink to each of inner storage tanks in printing cartridges 70-76 is controlled. When the quantity of the ink in each of the inner storage tanks is little, the ink in the respective ink storage tank 80-86 outside the carriage is sucked into the inner storage tank in the respective printing cartridge 70-76 by the vacuum-pressure in the inner storage tank connected to the respective ink storage tank 80-86 outside the carriage. At that time, the height of each of the ink storage tanks 80-86 outside the carriage is varied, then the vacuum-pressure is adjusted, thereby the quantity of the ink sucked into the inner storage tank is controlled.

Title: Semiconductor ac switch damage detection device
IPC: H02H7/20
Filed: 1992-03-10
Abstract: PURPOSE:To eliminate the need for a high breakdown voltage detection device and reduce cost by detecting current which flows a semiconductor switch element connected in inverse parallel with a DC current transformer and judging damage of each semiconductor switch element according to logical relationship of presence or absence of the DC current and presence or absence of a gate signal to each semiconductor switch element. CONSTITUTION:A DC current which flows to semiconductor switch elements 2 and 2' is detected by hole current transformers 3 and 3' and is supplied to an abnormality detection circuit 7 through an adder 4. At this time, a polarity of output current of the current transformer 3' is inverted and added. Therefore, presence or absence of current which flow the elements 2 and 2' is equivalent to presence or absence of output signal of the adder 4 and an abnormal state of the damage of the elements 2 and 2' is detected by controlling the logical relationship of the presence or absence of output signal of the adder 4 and the presence or absence of a control signal 6 by the abnormality detection circuit 7. For example, when there is no output signal of the adder 4 while there is the control signal 6, at least either of the elements 2 and 2' loses an inverse rejection capacity and a bi-directional AC current flows.
