Title: D/a converter
Inventor: MUROTA TOSHIO
IPC: H03M3/02
Filed: 1999-07-23
Abstract: PROBLEM TO BE SOLVED: To output analog data of high quality less affected by a clock jitter even if D/A conversion is executed by installing a digital filter attenuating delta/sigma modulation data. SOLUTION: A digital filter is installed behind a delta/sigma modulator 1 and the high-pass component of digital data is attenuated. Since the edge of a pulse waveform after digital/sigma modulation fluctuates, a pulse area changes at random and noise occurs. Thus, the occurrences of the edge of the pulse waveform is reduced and therefore the affect of a clock jitter can be suppressed. The reduction of the occurrences of the edge in the pulse waveform is equal to the attenuation of the high-pass noise of noise shaping. Consequently, the delta/sigma modulator 1 executes digital modulation and the digital filter 2 suppresses high pass noise. Then, a sampling rate can be reduced by sufficiently attenuating high pass noise.

Title: Discrimination of acceptable and defective products of ceramic heaters
Inventor: ROPPONGI TOSHIAKI
IPC: F23Q7/22
Filed: 1988-08-25
Abstract: PURPOSE:To discriminate the acceptability of a ceramic heater and prevent corrosion of a heater part from occurring after measurement by immersing an electrode and a ceramic coating part of the heater part in an aqueous solution of a carboxylic acid having a high dissociation constant, and impressing a predetermined voltage between the electrode and the heater part to measure the electric resistance therebetween. CONSTITUTION:A ceramic heater 1 comprises a cylindrical heater part 1a made of tungsten, an alumina-made columnar core part 1b with a circular cross section, and an alumina coating part 1c. A 1% aqueous acetic acid solution F is contained in a vessel 3 comprising a highly insulating material, and the coating part 1c of the heater 1 is immersed therein. The vessel 3 is provided with an electrode 2a comprising a platinum-plated titanium wire. A voltage supplied from a DC power supply 4 is impressed between the heater part 1a and the electrode 2a, and the electric resistance therebetween is measured by a resistance meter 6. The presence or absence of pores in the coating part 1c can be discriminated based on the magnitude of the resistance measured, whereby the acceptability of the ceramic heater can be discriminated. Even when acetic acid in the solution F is dissociated, the resultant ions do not react with the coating part 1c or the heater part 1a, so that corrosion of the heater part 1a after the measurement can be obviated.

Filed: 1989-08-16
Abstract: PURPOSE:To facilitate layout by displaying a rectangular pattern in superposition together with layout images on a display device and providing an automatic correction function for the layout position along the rectangular pattern. CONSTITUTION:Two kinds of the images are displayed in superposition on the same screen on a layout screen 12. The rectangular patterns are displayed by a 1st color and the layout images by a 2nd color, respectively. Since the rectangular patterns are displayed by the display type different from the display type of the layout images, for example, by the different color and, therefore, the generation of confusion in the layout operation is obviated. Since the contour rectangle to enclose the circumference of the merchandise information to be laid out by an operator are defined, the operator eventually makes the layout operation while displaying this contour rectangle. The position is so corrected that at least one vertex of this contour rectangle overlaps on the vertex of the rectangle constituting the rectangular pattern when the operator assigns the layout position at this time. The merchandise information is easily laid out in this way along the rectangular pattern.
