Inventor: KAWAKAMI NOBUO
IPC: G11B5/851
Filed: 1985-12-24
Abstract: PURPOSE:To improve the productivity by arranging oppositely plural targets and bases around the coaxial shaft in a vacuum chamber and providing the bases rotatably around the coaxial shaft. CONSTITUTION:In forming film of target material onto bases 3a-3d by using a film forming device, when sputtering is applied while the bases 3a-3d are driven by a proper angular velocity around the coaxial shaft O, the four rotating bases 3a-3d are faced intermittently with the targets 2a-2d arranged while being split into four in the circumferential direction and the film forming is applied while the bases 3a-3d are given to the glow discharge field. Thus, the bases 3a-3d are exposed to the discharge field intermittently and sputter particles are adhered intermittently. The bases are heated during the film forming, but when they are at the outside of the glow discharge field, they are cooled effectively by the water cooling at the back side in addition to the cooling by Ar gas in the chamber 1 and the temperature rise is stopped at a far lower temperature by a conventional device.

Title: Halftone display circuit
Inventor: TACHIBANA TAKASHI
IPC: G09G5/00
Filed: 1988-11-24
Abstract: PURPOSE:To increase the number of expressible gradations of halftone display circuit without lowering the resolution so much by collectively coding digital R, G and B signals by a prescribed number of bits and obtaining intermediate luminance values by decoding the coded digital R, G and B signals. CONSTITUTION:Digital R, G and B signals outputted from a personal computer or VTR, etc., are collectively coded by a prescribed number of bits at serial- parallel conversion circuits 4-7 and the collective information are decoded by means of a decoder so that the information can be converted into data for displaying intermediate luminance values. When, for instance, n-bit parallel data are obtained at the circuits 4-7, half-tone displays of 2<n> gradations become possible to each R, G and B signal. While the resolution drops to 1/n, in this case, the influence of the resolution drop is small as compared with the grada tion number of 2<n>. Therefore, the number of expressible gradations can be increased.

Filed: 1997-10-29
Abstract: PROBLEM TO BE SOLVED: To prevent an electromagnetic wave absorption filter from coming in contact with PDP(Plasma Display Panel) unit due to deformation caused by heat, humidity, etc. SOLUTION: A front side part of a front case is made to be a curved form so as to become convex to the viewer side. And, an electromagnetic wave absorption filter 6 is fixed on a front face (guide part 1v) of a frame surrounding an opening part 1a arranged corresponding to a PDP unit 3 with double coated adhesive tape 7. In this state, the electromagnetic wave absorption filter 6 is also convex to the viewer side. Therefore, when the electromagnetic wave absorption filter 6 is thermally expanded, the electromagnetic wave absorption filter 6 is deformed in the direction in which the curve is increased to the viewer side. Therefore, it does not come in contact with PDP unit 3. Moreover, even when the electromagnetic wave absorption filter 6 is compulsorily deformed to the side of PDP unit 3 by an external force, the electromagnetic wave absorption filter 6 is restored by its repulsion.

Title: Formation of polarizing film of liquid crystal display element
Inventor: OTA KAZUHIDE
IPC: G02F1/1337
Filed: 1987-11-26
Abstract: PURPOSE:To form the polarizing film which is formed in an easy process and durable and functions as an orienting film by forming a high polymer film on a transparent substrate and rubbing it, and then doping iodine. CONSTITUTION:The high polymer film 3 is formed on the transparent substrate 1 and subjected to rubbing to produce a mechanical groove structure and also rearray a polymer nearby the surface. The iodine is doped to remain covered as a chained high polymer in the rubbing direction. Conduction electrons of this iodine are movable in the longitudinal direction of molecules and can not move vertically, so polarization is selected. Consequently, when the polarizing film 3 is formed inside the transparent substrate in contact with the liquid crystal layer 5, it functions as the orienting film and the durability is improved because the film is inside the transparent substrate 1 as compared with a case wherein the polarizing film is stuck outside the transparent substrate 1.

Title: Printing position setting of manual printer
Inventor: MUTO TAKESHI
IPC: B41J2/51
Filed: 1989-11-16
Abstract: PURPOSE:To make it possible to set a printing position based on a positioning line by using the position of a head part when a positioning mark is adjusted to the head of a text as a reference position and a position away from the reference position by an offset value as a printing start position for the head of a character string. CONSTITUTION:An operator controls a panel 90 to enter characters to be used for printing and at the same time, gives a position for a character string 102 to be adjusted to a positioning mark M as a reference position for printing. A controller 96 calculates the length L of a single line of an input character string, then stores the length L in memory. Next the controller calculates an amount of movement D of a head part 23 in a printing direction. This amount D is  x, that is, an offset amount, when the reference position for printing is set to the head of a character string. The amount D is stored in memory 98. A casing 2 is placed on paper 104 and the mask M is adjusted to a character head position 106. After this, a counter is reset and a position pointed to by the mark M is given as a reference position for printing S, and the head part 2 is moved to a printing direction. In this case, the controller interprets the movement of the head part 23 to a position A in a minus direction.

Title: Dielectric filter, dielectric duplexer and communication device
Inventor: OKADA TAKAHIRO
IPC: H01P5/08
Filed: 1998-10-20
Abstract: PROBLEM TO BE SOLVED: To secure the external connection with no degradation of Qo of a resonator and also obtain the inexpensive and satisfactory characteristic of a dielectric filter by deleting at least a part of the ridgeline between the open end face and the mounting face of a dielectric block and forming at least an input/output electrode that is capacitively coupled to a prescribed inner conductor over the deleted part and a mounting part of the dielectric block. SOLUTION: A slope 1a is formed by deleting the crossing ridgeline between one of both open end faces and the mounting face of a dielectrtic block 1. The input/output electrodes 6a and 6b are formed on the surface 1a, and the distance is partly shortened between the inner conductors 3a and 3b to secure the larger external coupling capacity Ce. That is, the necessary external coupling is attained without increasing the areas of the electrodes 6a and 6b even when these electrodes are formed at the positions near the open end faces. Thus, the desired characteristic is obtained with no degradation of Qo of a resonator while maintaining the necessary external coupling. Furthermore, the electrodes 6a and 6b can be easily formed owing to existence of the slope 1a and the dimensional accuracy is improved for both electrodes 6a and 6b.

Title: Image processing method making use of error diffusion and halftone processing
Inventor: JIGAN FUAN
IPC: G06T5/00
Filed: 1995-10-23
Abstract: PROBLEM TO BE SOLVED: To suppress the deterioration of a picture quality to the minimum by combining error distribution with a halftone method by correcting an error resulted from quantization only in a significant block. SOLUTION: A picture is divided into blocks which do not have a common part. Each pixel is leveled according to a proper threshold value decided from a halftone cell which is being used. Next, a threshold value B generating an ON pixel and a threshold value W generating an OFF pixel are decided. When W>B, an output pattern obtained from the result of leveling is judged as a full dot pattern, and the level of the data input to each block is obtained. When it is judged that they have the same quality, the significant local error of each block is calculated. When they are judged as significant blocks, an error resulted from quantization is corrected in those blocks.
