Title: Schmitt circuit
Inventor: KUNITOKI TADAYOSHI
IPC: H03K3/353
Filed: 1986-06-12
Abstract: PURPOSE:To stabilize a threshold value, and to vary a hysteresis width, by providing a reference voltage generation circuit which generates a prescribed threshold value voltage, a comparator between each threshold value voltage, and an input voltage, and a latch circuit which outputs a hysteresis characteristics. CONSTITUTION:A reference voltage generation circuit I voltage divides a power source voltage Vcc, and generates a threshold value voltage Vth1 at a point P1, and a threshold voltage Vth2(<Vth1), at a point P2. A comparator II compares an input voltage Vin with the voltage Vth2at transistors TR P1, P2, N1, and N2, and compares the input voltage Vin with the voltage Vth1 at TRP3, P4, N3, and N4, and inputs voltages VN2 and VN4 which are results decided by nodes N2, and N4 respectively, to an output latch circuit III. The voltages VN2 and VN4. change to '0' or '1' by the input voltage VIN, and the outputs VOUT1 and VOUT2 of the circuit III change corresponding to the '1' or '0' of the VN2 or the VN4, and the output having the hysteresis width of a difference between the threshold values Vth1 and Vth2is generated, Therefore, it is possible to obtain the Schmitt circuit capable of varying an input threshold value by coupling the circuits I-III.

Title: Device for stopping rotation of head of drop seal mechanism
Inventor: KANEKO HIROSHI
IPC: H01J9/26
Filed: 1984-07-02
Abstract: PURPOSE:To prevent any crack generation by suspending the rotation of the head immediately before it is moved to the molding position. CONSTITUTION:When a head 7 comes to position (A') while rotating a stopper 6 does not touch a stopper 5 and the rotation of the head 7 is not suspended because the stopper 5 is in a position drawn by the broken line. When an air cylinder 12 is actuated right before the head 7 moves to position (A), a lever 13 which has been pushing the stopper 5 detaches from the stopper 5 and the stopper 5 is rotated by a spring 8. As the result, the stopper 5 moves forward as indicated by the solid line to cause the stopper 5 to touch the stopper 6 thereby stopping the rotation of the head 7. The bound of the head 7 accompanying the suspension of its rotation is completely attenuated during the time when the head 7 moves from position (A') to position (A). Therefore, the time required between suspension of the rotation of the head 7 and initiation of molding can be minimized. Consequently, it is possible to prevent any crack generation.

Title: Carrying system
Inventor: KOYANO SHINJI
IPC: B60L13/06
Filed: 1994-06-17
Abstract: PURPOSE:To reduce power consumption and carrying weight while preventing generation of heat and gas by adjusting the gap between a levitation body and a sensor part (i.e., the gap between an electromagnet and a target opposing each other) within a range controllable with small quantity of exciting current. CONSTITUTION:A set of electromagnets 6, 16 are disposed, respectively, on the V-axis and W-axis at the rear end of a carrier body 4 while opposing the inner peripheral surface of a bulkhead 1. A set of sensor parts 8, 18 are disposed closely to the V-axis and W-axis on the outer peripheral surface side of the carrier body 4 in order to detect the levitating position of a levitation body 3 on each axis.

Title: Image forming device
Inventor: YOSHIYAMA TSUGIHITO
IPC: G03G15/04
Filed: 1996-05-30
Abstract: PROBLEM TO BE SOLVED: To obtain a proper image without a toner fog and reduction in the density of an image by correcting image forming conditions with a correction value different in the polarity of the charge of a photoreceptor. SOLUTION: A photoreceptive layer is shaved because of consumption and the thickness of a film is reduced. The decrease of the film thickness is proportional to the number of the revolutions of a photoreceptor, so that a cumulative number of revolutions or a cumulative rotational time is counted to calculate the nearly exact decrease of the film thickness from the rate of the shaving of the film experimentally obtained in advance. In other words, the sensitivity of the photoreceptor can be corrected in such a manner that a voltage applied to an exposure lamp can be increased by 1V, whenever the thickness of the film is reduced by 0.7μm, when electrification to a positive polarity is attained. Therefore, the number of the revolutions of the photoreceptor required for shaving by 0.7μm/time is previously set and stored in the ROM of a CPU 51. Whenever the number of the revolutions/the time counts its set value by a counter 53, a lamp voltage is increased by 1V. The CPU 51 decides whether the polarity of the charge is positive or negative with an image forming mode signal and corrects the lamp voltage, according to the counter value of the counter 53.

IPC: G03G15/08
Filed: 1993-06-07
Abstract: PURPOSE:To prevent the unwanted peeling of a sealing member and the scattering of toner surely by interrupting a driving force transmitting path, when a toner cartridge is not set. CONSTITUTION:When the toner cartridge TC is inserted into the housing recessed part 100 of an image forming a device, a pushing rod 100 bends a shutter member S at the time of completing setting, so that the free side end part FE of the shutter member S is slid to open a driving member inserting hole 1c. Thus, a driver 7 can be connected to the fitting groove 5A4 of a disk part 5A1 through a driving member inserting hole 1c. In other words, when the toner cartridge TC is not completely set in the housing recessed part 100, the sealing member 3 is not peeled so that the scattering of the toner caused by the unwanted opening of the toner cartridge TC can be surely prevented.

IPC: G11B5/84
Filed: 1998-05-19
Abstract: PROBLEM TO BE SOLVED: To provide a manufacturing method, for a magnetic recording medium, which comprises a laser texture machining method suitable for forming a small- diameter single-ridged bump. SOLUTION: A Gausssian beam from a pulse laser oscillator 1 is converted, by a beam converter 6, into a ring-shaped beam 7 in which a light intensity distribution in the section of the beam in its nearly ring-shaped part is strong as compared with the central part. The ring-shaped beam is deflected by a mirror 3, and it is passed through a condensing lens 4 so as to be condensed on the surface of a ring-belt region on the inner circumferential side of a substrate 5 which is turned and advanced side by side. Since a light intensity distribution becomes a ring shape in a section irradiated with a condensed spot, the temperature of the substrate 5 becomes high in a nearly ring-shaped part in the periphery as compared with the central part out of molten parts, and the surface tension of the substrate 5 is small.  As a result, a molten material is gathered in the central part, and a single-ridged bump in a small diameter (3 to 6 μm) is formed surely.
