Title: Method and apparatus for forming image
Inventor: MIYAMOTO AKIO
IPC: B41M5/26
Filed: 1999-11-04
Abstract: PROBLEM TO BE SOLVED: To form an image of superior light-fast and water resisting properties without bleeding with a high resolution inexpensively and uniformly by eliminating the problems of limitations on an image-forming material and clogging of nozzles which are demerits of an ink-jet system, and improving the damage by heat to a support and the image unevenness which are demerits of a thermal transfer system. SOLUTION: A solution for lowering a transfer temperature or an adhesive solution is applied imagewise to either a surface of a transfer recording layer 7 of a transfer body 9 or a surface of an image-receiving body 15 to transfer the transfer recording layer 7 to the surface of the image-receiving body 15, whereby a latent image is formed. At least one of the transfer body 9 and the image-receiving body 15 with the latent image is heated by a drying heating means 11, thereby evaporating at least part of a solvent included in the latent image. The surface of the transfer recording layer 7 of the transfer body 9 and the surface of the image-receiving body 15 are heated in close adhesion. The transfer recording layer 7 corresponding to the part where the latent image is formed is thus transferred onto the image-receiving body 15, and an image is formed.

IPC: G11B21/21
Filed: 1990-11-21
Abstract: PURPOSE:To obtain an efficient slider by forming a flat surface inclined laterally of rails at least at parts of the rails provided at a magnetic head slider in such a manner that the inclined surface is directed rightward or leftward with respect to a center line along the rail. CONSTITUTION:Rails 2a, 2b are provided on a magnetic head slider 1, and composed of air bearing surfaces 3a, 3b inclined longitudinally of the rails, air bearing surfaces 4a, 4b inclined laterally of the rails, and flat surfaces 5a, 6a, 5b, 6b to become air bearing surfaces. Accordingly, a spacing can be microscopically reduced without increasing a pressing load and without reducing the width of the slider. Since a recording density can be enhanced and a contact area with the surface of a magnetic recording medium can be reduced, adherence can be prevented.

Filed: 1987-12-14
Abstract: PURPOSE:To obtain the grain feeling of an image, in an image processor for applying noise to image data to perform image conversion, by correcting the image data larger when the image data of a detected pixel is small and correcting the same smaller when said data is large. CONSTITUTION:The image of a CCD sensor is read by an image reading part 1 to be stored in an image memory 2 in a digital form.

Title: Thermal printer
Inventor: OGUSHI AKIRA
IPC: B41J29/50
Filed: 1988-12-13
Abstract: PURPOSE:To prevent the vacant heating of heating elements by a method wherein the electric conduction to heating elements within a predetermined range on the both sides of a line thermal head is inhibited according to the size of specified sheet paper, and the electric conduction to all the heating elements is inhibited for a fixed time by a paper detection means. CONSTITUTION:All nip rolls 10 and 11, 14 are rotated together, and payed-out heat-sensitive paper is fed forward until being discharged by the nip rolls 14. During this time, when the heat-sensitive paper passes below a light receiving element 16, the light receiving element 16 outputs a paper detection signal by the interruption of an incident light. A controller 2 detects the rising of this signal. After a delay time which is determined to be slightly longer than a time required for the leading end of the heat-sensitive paper to reach between a thermal head 12 and a platen roll 13, the controller 2 moves down the thermal head 12 and transmits a signal to a computer to permit the transmission of an image signal of a printing pattern. Then, the thermal head is energized to start printing. When the tailing end of the heat-sensitive paper passes below the light-receiving element 16, the paper detection signal falls. With the detection of this falling, the controller 2 stops energizing the thermal head 12.

Title: Objective lens unit
Inventor: EGURO KOUICHI
IPC: G11B7/09
Filed: 1986-12-26
Abstract: PURPOSE:To simplify the whole of a movable part, to miniaturize in size and lighten in weight, and to perform an accurate following operation on a track, by winding a driving coil directly on an objective lens. CONSTITUTION:A focusing coil 11 is wound closely on the outer peripheral plane of the objective lens 10, and tracking coils 12a and 12b at the symmetric positions of the outer peripheral plane by coupling them. When the focusing coil 11 is energized, the objective lens 10 is displaced in a direction of an optical axis by magnetic flux generated in a magnetic circuit so as to coincide a light spot on the track of an optical disk accurately, meanwhile, when the tracking coils 12a and 12b are energized, the objective lens 10 displaces the light spot in the vertical direction of the optical axis. In this case, since the movable part is miniaturized and made light sufficiently by winding the coil directly on the objective lens 10, it is possible to support the objective lens 10 with a holding member with very weak elasticity. In such a way, a driving force by the magnetic circuit can be affected effectively, and the follow up of the objective lens 10 can be performed accurately.

Filed: 1987-12-10
Abstract: PURPOSE:To attain efficient information exchange between plural highways by using two kinds of time switches at the pre-stage and the post-stage and increasing the channel multiple degree while fixing the connection during that time more than that of an input/output highway. CONSTITUTION:The multiplex factor of the information inputted from each input highway IHW is increased more than that of the information by the input highway IHW by a 1st time switch 21 and the result is outputted to a highway CHW. The information of the channel decided fixedly at every output highway OHW is selected by a selector 22 receiving the information and the information extracted from each highway CHW is multiplexed. Thus, even when the packets are overlapped timewise on the input highway IHW, the multiplexing is attained. The information multiplexed in this way is outputted to the output highway OHW via a 2nd time switch 23.

Title: Ink sheet for electrothermal transfer recording
Inventor: MIYAWAKI KATSUAKI
IPC: B41J31/00
Filed: 1988-12-15
Abstract: PURPOSE:To make constant an electric current which runs regardless of the number of drive electrodes for recording electrodes and thereby make possible uniform printing with pixels by forming unvaporized streaks in a paper feed direction during printing of a conductive layer at an interval of l1 where the relationship of l1<l2 is established when the interval of the recording electrodes is l2. CONSTITUTION:A conductive layer 3 and an ink layer 2 are laminated with a resistance layer 4 in contact with a recording electrode 7 placed under the latter. The resistance layer 4 is formed by dispersing conductive carbon in a heat-resistant polymer, then aluminum is vaporized and deposited on the resistance layer 4. For instance, the resistance layer is about 5 to 8mum thick, while the conductive layer 3 is about 0.1mum thick. Ink is applied on the conductive layer 3. After this, unvaporized streaks 3a are formed at an interval of l2 in parallel with a sheet feed direction on the conductive layer 3. The width of the unvaporized streak 3a is a few micron meters. If the interval between the recording electrodes 7 is l2, l1 becomes a value of l1<l2. A return electrode 8 is so designed as to come in contact with an ink sheet 1 with a wider area than the recording electrode 8.

Likewise, a stop command current of the motor being previously operated is set as an initial value, an increment unit command current value and a decrement unit command current value to the remaining pump motor are set on the basis of the reference current value Ik in advance. As for a first pump 4-1, a starting command is generated by turning the switch 8 to ON, and when this switch 8 is in a state of being turned on, a current of a motor M3-1 is measured, and the detected value and the reference value at that time is taken up, and each setting value of the increment unit command current and decrement unit command current value is compensated by this deviation.
