Title: Power system stabilizing equipment
Inventor: KANBARA ICHIRO
IPC: H02P9/14
Filed: 1993-04-27
Abstract: PURPOSE:To improve the stability of a power system, by deriving the q-axis current of a synchronous machine from its terminal voltage and its output current, and by making the q-axis current a stablized signal. CONSTITUTION:The terminal voltage and output current of a synchronous machine 1 obtained respectively from a voltage transformer 2 and a current transformer 3 are converted by a transducer 41 for a power into the effective power, reactive power and terminal voltage of the synchronous machine 1, and these are inputted to a q-axis current transducer 42. In the q-axis current transducer 42, first, effective and reactive currents are calculated, and then, the q-axis current of the synchronous machine 1 is calculated. In a stabilizing circuit 43, the output signals of the transducer 42 are converted from their stationary values into their deviation signals, and after their delaying, leading, and gain compensations, an automatic voltage regulator 5 is controlled by their stabilized signals. Thereby, the stability of a power system is improved.

Title: Fuel injection valve
Inventor: ISHIKAWA TORU
IPC: F02M61/18
Filed: 1991-05-28
Abstract: PURPOSE:To improve the fuel distributing performance of a multi-way spray fuel injection valve for injecting fuel into a multiple intake engine so as to heighten engine performance such as the decrease of HC and low temperature startability. CONSTITUTION:The hole (orifice) 11 of a nozzle provided at a fuel injection valve is formed into polygonal or elliptic shape suitable for desired spray split. The distribution performed by a nozzle adapter 13 is improved by optimizing the shape of the nozzle hole 11 so as to heighten engine performance. In the fuel injection valve for a multiple intake engine, the fuel is thereby approximately regulated in the divided number and directions by the nozzle hole positioned on the upstream side of the fuel dividing member, so that a fuel distributing characteristic is improved to heighten engine performance such as the decrease of HC and the improvement of low-temperature startability.

Title: Optical measuring method
Inventor: SAITO KENJI
IPC: G01B11/00
Filed: 1985-06-08
Abstract: PURPOSE:To eliminate influences of movement of a light source by reflecting two optical beams on an object to be measured and a reference object and condensing them with an optical element to generate optical beams inverted in two directions orthogonal to each other. CONSTITUTION:An optical beam 2 emitted from a light source 1 is divided by a beam splitter 6, and one optical beam 2b passes an image rotator 7 and is reflected on an object 3 to be examined. The other optical beam 2a is reflected on a reference face 8, and they are condensed by a lens 4 and are irradiated to the light receiving face of a PSD 5. Though variation components of the light source in the division direction of the splitter 6 are eliminated, those in the direction orthogonal to this division direction are not affected by the splitter 6. The fact that the passing position of the optical beam is inverted by the rotator 7 is used to invert the variation direction of a varied optical beam 2b'. Thus, influences of direction deviation of the optical beam due to the variation of the light source are eliminated.

Title: Transmission rate converter
Inventor: ABE SHUJI
IPC: H03M7/00
Filed: 1996-05-17
Abstract: PROBLEM TO BE SOLVED: To prevent overflow or underflow of a reception buffer even in the case of transmission of a constant bit rata(CBR) stream converted from a variable bit rate(VBR) stream. SOLUTION: Input data are syntax-decoded by a syntax decode section 2 and a measurement result relating to a code amount is obtained. A control section 4 calculates the code amount to be deleted or added based on the measurement result. Fox example, in the case of conversion into a CBR stream, if a reception buffer underflows, the control section 4 provides an output of information to reduce an AC component (AC) coefficient. Thus, the AC coefficient is deleted from a VBR stream. A transmission buffer 7 converts the VBR stream into a CBR stream and provides an output of the CBR stream. Since the AC coefficient is reduced, even in the case of receiving the CBR stream, no underflow takes place in the reception buffer.

Title: Vibration type transducer
Inventor: IKEDA KYOICHI
IPC: H01L29/84
Filed: 1990-05-14
Abstract: PURPOSE:To easily adjust the tension or temperature coefficient of a vibration beam part by covering the surface of the vibration beam with the 1st layer of an oxide film and its surface with the 2nd layer of polysilicon, and adjusting the film thicknesses of both layers and adjusting the tension generated by the vibration beam and both layers. CONSTITUTION:When the vibration beam 3 is made of high-density boron silicon, about 100 - 300mu tension is obtained depending upon the boron density and when the 1st layer of the oxide film is formed, the compressive force is generated to vary the tension with the film thickness of the 1st layer, thereby adjusting the tension of the whole part of the vibration beam 3. Further, the 2nd layer of polysilicon whose tension is almost 0 provided on the external surface of the 1st layer to approximate the tension of the whole part of the vibration beam 3 to 0, so the tension can easily be adjusted on the whole. Consequently, the vibration transducer which can easily adjust the tension or temperature coefficient of the part of the vibration beam 3 is realized.
