IPC: G11B5/31
Filed: 1986-05-23
Abstract: PURPOSE:To eliminate the adverse influence of the wear, crush, etc., and to remarkably increase the lifetime of a magnetic head, by covering the head with a BN film at the side of its rubbing face to a recording medium to reduce the frictional coefficient between the head and the recording medium. CONSTITUTION:A BN film is covered over a magnetic head consisting of a ferrite magnetic substance or a magnetic substance and a nonmagnetic substrate at the side of a rubbing face to a recording medium. The 100-1000Angstrom  thickness suffices with the BN film and both hexagonal and amorphous states are available with the BN film. Then a vacuum deposition process, a sputtering process, an ion plating process, etc., and available with this coating. In such a way, the frictional coefficient is remarkably reduced between the magnetic head and the recording medium. Then the mechanical reliability of the magnetic head is improved and at the same time the corrosion resistance of the magnetic substance is extremely improved against the water environment, etc., in particular with a thin film magnetic head. Thus the lifetime of the magnetic head is increased.

Abstract: PURPOSE:To reduce a discharge probability between electrodes by dividing a line memory for holding the data corresponding to one horizontal scanning into multiple numbers, and connecting horizontal control electrodes in common with the division number, and dividing an electron fetch electrode into the same number in response to the division. CONSTITUTION:A line memory M for holding the data corresponding to one horizontal scanning is divided into multiple numbers, and electrodes 16 in the horizontal direction for amplifying and modulating the output from this line memory M are connected in common with the division number, and an electron beam fetch electrode 18 in the longitudinal direction of a linear cathode 12 is divided into the number as same as the division number. Consequently, the number of terminals of the electron beam fetch electrode 18 can be reduced to one-several of a conventional one. The number of driving LSI is thereby reduced, and a space between electrodes adjacent to each other is widened to reduce a discharge probability.

IPC: H03H17/02
Filed: 1992-05-12
Abstract: PURPOSE:To improve the computing accuracy, the rounding error, etc., while maintaining the arithmetic linearity by performing the arithmetic of a digital filter with repetition of the product sum operation and limiting a numerical expression range based on the maximum value that can be secured by the output of the arithmetic of the digital filter. CONSTITUTION:The internal numerical expression range of an arithmetic processor is limited to the numerical expression L (numerical expression that can show + or -L) which can show the maximum value Ymax that can secured by the arithmetic result Y (n) of a secondary IIR type digital filter in a computing method where the arithmetic of the digital filter is carried out with the repetitive addition of the multiplication results with use of the optimization method of the internal numerical expression of the arithmetic processor. The digital filter uses an arithmetic processor of a 16-bit fixed decimal point in expression of a complement of 2. Therefore, the filter signal input 1 and the filter coefficients B1-B3, A2 and A3 are expressed in the 16-bit fixed decimal points. Even if an overflow or an underflow occurs during an operation, the operation is never saturated to the maximum or minimum value and carried on as it is.

Abstract: PROBLEM TO BE SOLVED: To uniformly form images even in the case of high-speed printing without increasing a circuit scale at low cost by controlling to reduce or increase a heat generation amount of a printing part when printing in accordance with a history of image data. SOLUTION: An image data memory means 3a stores data of five pixels from the past to future from input image data. A pattern memory means 3b stores combinations of strobes of different terms obtained by dividing one scan line to three. A combination operation means 3 supplies to a thermal head 4a the strobe of an appropriate pattern from the pattern memory means 3b on the basis of a history of image data stored in the image data memory means 3a. For instance, the combination operation means supplies a third strobe to a pixel element which does not print this time and prints next time, thereby controlling to preheat the element. At the same time, the combination operation means supplies only a first, a second strobes to a pixel element which prints previously and prints also this time, thereby controlling to decrease heat of the element.

Title: Vacuum microswitch
Inventor: ENDO FUMIHIKO
IPC: H01J21/06
Filed: 1995-05-18
Abstract: PURPOSE: To enhance reliability by enclosing an overvoltage protective part in the same element by dividing a gate, and bypassing overvoltage by automatically turning it on when the overvoltage is detected. CONSTITUTION: A gate is divided into two parts of G0 and G1, and a main switch part 10 and an overvoltage protective part 11 are arranged in the same element. When voltage between A and K is not more than an overvoltage protective level, the protective part 11 does not operate, and the switch part 10 operates by an ON signal of a driving device 12. When it is not less than the overvoltage protective level, an overvoltage detecting circuit 13 detects this, and operates a gate pulse generator 14, and turns the protective part 11 on, and bypasses the voltage between A and K. When it reduces to the overvoltage protective level or less, the generator 14 is stopped, and the protective part 11 is turned off. In this way, the protective part 11 is automatically turned on, and since overvoltage is bypassed and restrained, reliability can be improved.

Title: Dielectric resonator device
Inventor: NISHIKAWA TOSHIO
IPC: H01P1/20
Filed: 1985-05-31
Abstract: PURPOSE:To make a device small-sized and low-cost by allowing the direction of lines of magnetic force generated in a loop to coincide with the direction of lines of magnetic force of a resonance mode to be coupled in an input coupling means and allowing that to interlink to the direction of lines of magnetic force of the resonance mode to be coupled in an output coupling means. CONSTITUTION:Three prismatic dielectrics joined orthogonally to one another into one body are arranged in a rectangular parallelepiped-shaped cavity shield case to use resonances of TM110 modes existing in respective axial directions of prismatic dielectrics or their deformation modes, and the dielectric resonator constituted in this manner and an external circuit are coupled. In the odd mode, the magnetic energy is stronger than the electric energy near a coupling control member 4a, and the electric energy is stronger near a coupling control member 5a. In the even mode, the electric energy is stronger near the coupling control member 4a, and the magnetic energy is stronger near the coupling control member 5a. Consequently, coupling is zero practically if coupling control members 4a and 5a are taken in and out to equalize resonance frequencies in the odd mode and the even mode. Thus, the device is made small-sized and low-cost.
