Title: Amplitude phase measurement system and amplitude phase measurement method
Inventor: KAKIHARA SHIYOUJI
IPC: H04L27/18
Filed: 1998-10-21
Abstract: PROBLEM TO BE SOLVED: To easily measure and adjust quadrature modulation waves and to reduce excessive circuits mounted on a substrate as much as possible. SOLUTION: In the quadrature modulation circuit board 5 of a double conversion system, the monitor output of respective synthesizers 10 and 11 as local signal generators is frequency-converted in a mixer 6-1 on a jig substrate 6. In a network analyzer 7 which is an amplitude phase measurement device, the output of the mixer 6-1 is turned to a reference signal and the modulation amplitude and modulation phase of modulation output from an output terminal 9 are measured. Also, a band-path filter 6-2 for eliminating unrequired waves is provided. Thus, since local signals led out from a monitor terminal are used, the need of providing a changeover switch for leading out the output of a modulator 5-1 is eliminated, and the phase and amplitude value of quadrature modulation output are measured/adjusted by using the final output of the modulator.

Title: Viscous coupling
Inventor: TERAOKA MASAO
IPC: F16D35/00
Filed: 1988-11-29
Abstract: PURPOSE:To enable an escape to be promptly attained from a slip condition by providing the second resistance plate to be arranged adjacent to a pair of first resistance plates and several blocks to be arranged in an operating chamber with these first and second resistance plates serving as a single block, in the case of a viscous coupling built in a power transmission system for a vehicle or the like. CONSTITUTION:Silicone oil, interposing between a pair of first resistance plates 7 and rotating with the first resistance plate 7, generates a static pressure, and silicone oil, interposing between the first and second resistance plates 7, 8, generates a dynamic pressure, with the dynamic pressure between the first and second resistance plates 7, 8 relatively lower than the static pressure between the pair of first resistance plates 7. While the larger is a difference between relative rotary speeds of the first and second rotary members 1, 5 the larger difference is generated between these static and dynamic pressures. Accordingly, the first resistance plate 7 is moved toward the second resistance plate 8 against urging force of a spring 13 by this differential pressure, reducing a clearance between the first and second resistance plates 7, 8. Thus increasing shearing force of the silicone oil, this shearing force is transmitted to a rear wheel as torque.

Title: Evaluating method of ultraviolet light resistant performance of same kind of resin laminated material
Inventor: MIYAZAKI YOSHIJI
IPC: G01N21/896
Filed: 1996-11-12
Abstract: PROBLEM TO BE SOLVED: To enable the evaluation of ultraviolet light-resistant performance without the need for the measurement of thickness by obtaining a transmission attenuation index by irradiating a laminated material which comprises a resin base material and a protective layer formed by adding an ultraviolet absorbing agent to the same kind of resin with ultraviolet light with a predetermined wavelength. SOLUTION: An object to be measured 2 comprises a resin base material 2a and a protective layer 2b formed by adding an ultraviolet absorbing agent to the same kind of a resin and is made up of a resin transparent to ultraviolet light. At the time of evaluation, the resin making up a laminated material is irradiated with harmful ultraviolet rays of a predetermined wavelength from the side of the protective layer 2b, the amount of transmission is measured by a sensor 3 to obtain its transmission attenuation index and the amount of ultraviolet light is quantified by a processing device 4. Here the resin without containing an ultraviolet absorbing agent hardly absorbs ultraviolet light, and the attenuation of ultraviolet light occur almost all over the protective layer 2b.  Therefore, by the transmission attenuation index over the whole laminated material, the performance of the protective layer 2b on which performance in use is dependent is evaluated. By this, it is possible to evaluate the performance of the protective layer of the same kind of resin laminated material which is usually fused to be integrated and difficult to separate without the need for the measurement of thickness.

Title: Audio equipment containing battery and audio signal amplifier circuit
Inventor: FUNABASHI HIROYUKI
IPC: H03F1/30
Filed: 1992-10-13
Abstract: PURPOSE:To provide an audio equipment containing a battery and an audio signal amplifier circuit so as to amplify the audio signals with no distortion even at a low power voltage level. CONSTITUTION:A control current generating circuit 3 generates a control current Im of a level accordant with the power voltage Vcc and the reference voltage VB. The current Im is applied to the feedback input terminal (-) of an amplifier 1. Thus the base potential of the transistor of the first stage is held at a prescribed level as a precondition for operation of the amplifier 1. Furthermore the base current is controlled. Then the operating point voltage of an output signal B is set at the middle level (Vcc/2) of the voltage Vcc. Thus it is possible to amplify an audio signal A with no distortion even at a low power voltage as well as at a high power voltage level.

Filed: 1988-11-30
Abstract: PURPOSE:To obtain high C/N by providing a recording film comprising an Au-Te alloy, carbon, nitrogen, fluorine and hydrogen to record information therein by irradiation with a laser light, on a substrate. CONSTITUTION:A substrate 13 is formed from a material which is transparent to a laser light with which an information recording medium is irradiated for recording and reproduction of information.

For formation of pits at a melting temperature approximate to or lower than the melting point of Te, uniformity of pit size, formation of less rim parts and an increase in recording density, the Au content is set in the range of 2-47atom%. This construction makes aperture diameters of pits smaller and uniform, so that a high C/N can be obtained.

Filed: 1988-11-30
Abstract: PURPOSE:To simplify circuit constitution, and to miniaturize a circuit by constituting the circuit by providing two binary counters, a sine wave waveform data generating ROM and a low-pass filter, and performing both FSK modulation and AM modulation at a time by one set of a sine wave generation circuit.

Title: Method for reduction of dielectric contamination in integrated circuit
Inventor: FUERISHIA GARETSUTO HAARINGU
IPC: H01L21/302
Filed: 1992-11-12
Abstract: PURPOSE: To lessen the contamination of a dielectric layer in an integrated circuit due to heavy metal impurities by depositing the dielectric layer on a pattern, exposing it in a source of contaminant, and then eliminating a surface layer of the dielectric layer by a chemical reaction with the generation of a vapor-phase neutral atomic substance. CONSTITUTION: On a silicon wafer substrate 1, a pattern made of such material 3 as aluminum is formed. A dielectric layer 5, such as an oxide layer, is deposited on the pattern. A certain treatment is given to the dielectric layer 5, and thereby the dielectric layer 5 is exposed to a source of contaminant, including moving ions such as Na or heavy metal. Next, a surface layer of the dielectric layer 5 is eliminated by a chemical reaction with the generation of vapor-phase neutral atoms. For example, an etching gas, including NF3 , CF4 , SF6 and other materials, is put into a plasma source. The process proceeds at a low temperature and with low energy, so that any material under the patterned dielectric layer is not affected by the process. By this method, contamination of the dielectric layer by heavy metal can be lessened.
