Title: Thermal print head
Inventor: SHINTANI SUKEMASA
IPC: B41J2/345
Filed: 1979-10-08
Abstract: PURPOSE:To obtain an explicit picture quality in such a manner as causes dot gaps to be densely colored on a heat-sensitive recording sheet, by a method wherein reed electrodes are arranged in a zigzag at both sides of a common electrode, and they are arranged so that they overlap on their respective extension lines. CONSTITUTION:Given heating resistances 7 are heated by applying voltage to reed electrodes 6 at a side A and a beltlike common electrode 8. When, with this, heating resistances 7 at a side B are positioned at heating dot gaps, voltage is applied to reed electrodes 6 at a side B and the beltlike common electrode 8. The reed electrodes 6 at the side A and the reed electrodes 6 at the side B are located so as to overlap to each other, and thereby coloring dots become dense in a main scanning direction to obtain an explicit picture quality. The reed electrodes 6 are arranged in a zigzag but the heating resistances 7 are formed in a separation, which results in an easy printing process and permits the protection against the occurrence of systematic uneveness due to a current leakage produced in the beltlike heater.

Title: Thin film capacitor
Inventor: ABE KAZUHIDE
IPC: H01B17/62
Filed: 1992-05-22
Abstract: PURPOSE:To reduce a change with time of capacitance and the voltage polarity dependency of a leakage current in a thin film capacitor by a method wherein when a bias voltage is changed from a negative voltage to a positive voltage or from a positive voltage to a negative voltage, respective bias voltages, at which capacitances become largest, are set so as to satisfy specified relations. CONSTITUTION:A thin film capacitor consists of lower and upper electrodes 2 and 4 formed in opposition to each other via a high-dielectric constant thin film 3 of a film thickness of 350nm or thinner. When a bias voltage which is applied between the electrodes 2 and 4 is made to rise from a negative voltage to a positive voltage, a bias voltage, whose capacitance becomes largest, is assumed VCMAX+ and in contrast to this, when the bias voltage is reduced from a positive voltage to a negative voltage, a bias voltage, whose capacitance becomes largest, is assumed VCMAX-. At this time, the bias voltages at which capacitances become largest are set so as to satisfy the conditions of ¦VCMAX+-VCMAX-¦<=0.3 and -0.3<=VCMAX+<=0.3-0.3<=VCMAX-<=0.3 (The unit is V.). Thereby, the thin film capacitor, which has little change with time of capacitance and little voltage polarity dependency of a leakage current, can be obtained.

Abstract: PURPOSE: To provide a probe with a flat frequency response over a wider band by arranging a resistance means, a circuit network having a resistor and a capacitor and a coaxial cable determined by the input impedance and attenuation of a probe whose length is set to maximize a crossing dip. CONSTITUTION: A tip resistor Rt is brought as close as possible to a circuit 104 to be tested and made to stick out being separated as much as possible from a grounded printed circuit of a tip RC sub circuit network thereby minimizing a floating tip capacitance. A resistor Rc accomplishes both an attenuation of a signal and a higher input resistance at a low frequency and a capacitor Cc performs an attenuating function of a capacitive divider at a high frequency. The principal part of a high frequency attenuation is performed by the resistor Rt A terminal circuit network 140 terminates a cable 130 for a high frequency signal and resistors RS1 and RR2 perform another high frequency attenuation. A capacitor CS suppresses a high frequency ringing and the resistor RS3 attenuates a DC signal.  The length of the cable 130 is a function of an input impedance and the attenuation and the length of the cable 130 to minimize a crossing dip is approximated by the function.

Title: Electromagnetic acoustic transducer
Inventor: KAGAWA YUKIO
IPC: B06B1/04
Filed: 1994-06-14
Abstract: PURPOSE:To provide an electromagnetic acoustic transducer which is constituted so as to increase translation efficiency. CONSTITUTION:When large current is allowed to instantaneously flow from a pulse electric power generator 12 to a spiral coil 11, eddy current is generated in an oscillation radiator 11. At the same time, intensive electromagnetic repulsion force acts between coil current and eddy current and thereby the oscillation radiator 11 is vibrated. In this time, since the oscillation radiator 11 is constituted of a hemispherical shelllike conductor thin plate, harmful vibration caused by Poisson coupling is inhibited. Further, since structural rigidity is large, only piston action is excited and large powerful pulse acoustic wave is regularly radiated in the direction shown by an arrow.

IPC: H04N5/335
Filed: 1998-05-14
Abstract: PROBLEM TO BE SOLVED: To correct distortion of obtained data with high quality through a simple processing while utilizing the data effectively at maximum. SOLUTION: For example, in the case of correcting barrel shaped distortion, a circle (fixed circle) 12 whose center is the same as a center 11a of an image area 11 is set so as to be circumscribed with the image area 11. On the other hand, a distortion correction table to instruct which pixel data each pixel of image data obtained by an image pickup element is to use is generated in advance.

Furthermore, with respect to pixels in existence in the inside of the fixed circle 12, pixel data of correction object pixels are rewritten with pixel data of pixels in existence at the outside of the correction object pixels instructed by the distortion correction table.
