Title: Copying device capable of adding comment
Inventor: HONMA YOSHIYASU
IPC: G03B27/62
Filed: 1990-07-10
Abstract: PURPOSE:To easily add a comment in a universal font by providing a light shutter on an optical path which leads to a photosensitive body where light optically scanning an original forms an image and controlling exposure on the photosensitive body by the light shutter. CONSTITUTION:Light emitted from an exposing lamp 3 is reflected on the original 2, passes through the shutter 12 and is made incident on a fixed lens 4. Then, it exposes the photosensitive body 7 which rotates in a direction shown by an arrow 6. When a user inputs a date, etc., by an information input device 14, each unit shutter 12 is actuated by a shutter control circuit 13 connected to the device 14. That means, the light made incident on the lens 4 is controlled by opening and closing the shutter. Namely, when the shutter is perfectly closed, the light does not reach a corresponding part on the photosensitive body 7 at all and the part becomes black as a final output image. Thus, the comment is added to the output image by adjusting the exposure on the photosensitive body 7.

Inventor: YAMAUCHI KENJI
IPC: H03F3/68
Filed: 1993-07-27
Abstract: PURPOSE:To improve high-frequency characteristic and to reduce thermal agitation noise by directly inputting the both ends of the coil of a magnetic head into the non-inversion input terminals of the both of differential amplifiers and performing a differential amplification for the outputs of the both differential amplifiers by other differential amplifier. CONSTITUTION:The both ends of the coil of a magnetic head 1 are directly connected with each non-inversion input terminal of each operational amplifier A2 and A3 and resistances R11 to R13 and an inversion input terminal are connected as negative-feedback resistance of the amplifiers A2 and A3 with the both ends of the resistance R12, respectively. A differential amplification is performed for the outputs of the amplifiers A2 and A3 in a differential amplifier circuit composed by an operational amplifier A1 and resistors R1 to R4, in-phase voltage removal ratio and an S/N are made excellent and the influence of external noise is reduced. The resistance value of the resistor R12 is made smaller than the coil resistance value of the head 1, thermal agitation noise is reduced and the input impedance of a circuit becomes sufficiently high by this constitution. Thus, a high-frequency characteristic is improved, with high amplification faster and a wide band, and noise is also reduced.

Title: Manufacture of anisotropic magnet by dry molding
Inventor: KATO YOSHIO
IPC: H01F41/02
Filed: 1995-07-21
Abstract: PROBLEM TO BE SOLVED: To manufacture a magnet having high magnetic property and uniform thickness with high productivity and at low cost by dry molding. SOLUTION: In a process of manufacturing an anisotropic magnet by molding magnet powder in a magnetic field and then firing the molded magnet powder, the molding includes pressuring the magnet powder without applying the magnetic field to form a pre-molded compact having a theoretical density of 20-30%, and then pressuring the pre-molded compact in the magnetic field to form a compact. At the initial stage of compression molding, the pre-molded compact having a uniform density is obtained without applying the magnetic field. Then, by applying the magnetic field to the pre-molded compact, the relatively low density of the pre-molded compact causes each magnet powder to easily rotate to be oriented in the direction of the magnetic field.  However, the degree of freedom is not so high as to allow the movement of the magnet powder, and there is no possibility of generation of non-uniformity in the density of each part of the pre-molded compact.

Title: End mark forming method for thermal transfer recording medium
Inventor: MATSUNAGA KAZUO
IPC: B41M5/382
Filed: 1988-07-26
Abstract: PURPOSE:To lower the possibility of deformation, such as wrinkling, of a recording medium by a method wherein a sheet material capable of receiving a thermal transfer layer is brought into close contact with the thermal transfer layer, and a heated body having the shape of an end mark is brought into close contact with the sheet material to remove partially the thermal transfer layer at a terminal end part of the recording medium. CONSTITUTION:A sheet material 2 capable of receiving a thermal transfer layer 4 of a thermal transfer recording medium 3 is brought into close contact with the layer 4 st a terminal end part of the medium 3, and a metallic die 1 having the shape of an end mark is brought into close contact with the sheet material 2, thereby removing partially the layer 4 at the terminal end part of the medium 3. With the end mark thus formed on the recording medium 3, a force exerted on the medium 3 at the time of releasing is reduced, and the possibility of deformation such as wrinkling of the medium 3 is lowered. In addition, the quantity of heat given to the medium 3 is so small that a base film 5 of the medium 3 is hardly deformed. Further, the construction is simpler than the conventional constructions, and a long marking can be easily obtained.

IPC: H01L29/739
Filed: 1991-07-25
Abstract: PURPOSE:To uniformly distribute a current which flows from a collector electrode to an emitter electrode at on time without collecting in one part of the teeth by nearly equalizing the longitudinal resistance per unit length of the teeth of the comb-shaped emitter electrode and collector electrode whose teeth engage each other. CONSTITUTION:An emitter electrode 2 and a collector electrode 3 are in the condition that a plurality of teeth 2a and 3a are engaging each other.

Title: Driving circuit of display panel on which light emitting efficiency is improved
Inventor: SAKIDA KOICHI
IPC: G09G3/292
Filed: 1999-06-30
Abstract: PROBLEM TO BE SOLVED: To generate priming pulses having a high crest value by using a low power supply voltage by utilizing an oscillating circuit as a circuit which generates sustain discharging pulses having thin width priming pulses. SOLUTION: At time t0, only a switch SW1 is turned on, i.e., closed to constitute an oscillating circuit that is made up with a power supply SVp, an inductance L and a capacitance C between X-Y electrodes of a sustain electrode. In the oscillating circuit, an oscillating voltage, which has an amplitude Vp centered around the voltage SVp, is generated for the capacitance C. The oscillating signals are slowly attenuated by a parasitic resistance R which exists at either the X electrode or the Y electrode (refer to the dotted lines in the figure). Therefore, when a first peak voltage of the oscillating operation is completed, i.e., at time t1, the switch S1 is opened and a switch S2 is turned on, i.e., closed. Thus, a constant voltage Vs is applied to the capacitance C.  The solid lines indicate a wall electric charge forming pulse 32 which is made up with a thin width priming pulse 30 and a constant voltage Vs that is formed after the pulse 30 occurs.
