Output light beams of the waveguides 13a and 13b are guided to the optical multiplexer 14 and interface with each other. Their interference light is converted by the photoelectric converter 15 into an electric signal. Then the waveguides 13a and 13b are arranged in the same environment, so there is no output variation with temperature and a measurement is taken by utilizing the interference between the light beams, so the high-accuracy pressure transducer is realized.

Title: Control device of throttle valve
Inventor: MURAJI TETSURO
IPC: F02D41/04
Filed: 1997-10-21
Abstract: PROBLEM TO BE SOLVED: To compensate for additional torque by the action of an air flow at valve opening time, and improve responsiveness by impressing it on an actuator by adding an additional electric current value calculated by performing a prescribed operation on a speed to open a throttle valve to an electric current value by a PID control method. SOLUTION: An electric current value periodically supplied to a rotary solenoid 5 is calculated by a sub-ECU 2. That is, the sum of a deviation Ipid(n) of actual valve opening to target valve opening from a main ECU calculating an (n)th time target electric current value IX(n) by an ordinary PID control method and a compensating electric current value If (n) to additional torque generated by an air flow to a speed to open a throttle valve, is found by an expression [IX(n)=Ipid(n)+If (n)]. This target electric current value IX(n) is supplied to the rotary solenoid 5, and valve opening is controlled. Therefore, the responsiveness of the throttle valve can be improved.

Title: Car speed arithmetic device
Inventor: KATSUTA TOSHIHIRO
IPC: G01P3/489
Filed: 1991-10-25
Abstract: PURPOSE:To eliminate the judgement of car speed of zero during the traveling of a vehicle by prohibiting the car speed zero judgement during the time from the sharp variation of car speed to the input of the next car speed signal in cases where the car speed is judged zero when the car speed signal is not inputted for a prescribed period. CONSTITUTION:A car speed arithmetic device calculates car speed on the basis of the car speed pulse signal supplied from a car speed sensor not shown on the figure. In this case, if the car speed pulse signal is not inputted for a prescribed period, a car speed zero judging means judges the car speed of zero. While, a sharp variation car speed judging means judges the sharp variation of the car speed on the basis of the lapse of a prescribed period from the time when the newest car speed pulse signal is inputted. When the sharp variation of car speed is judged, a car speed calculation prohibiting means prohibits the judgement of car speed of zero, during the time up to the input of the next car speed pulse. Accordingly, the judgement of the car speed of zero is eliminated in spite of the traveling of a vehicle, and reliability is improved. Accordingly, the inadvertent generation of down shift is prevented.

Title: Magneto-optical disk
Inventor: TOMIKAWA NAOHIRO
IPC: G11B11/105
Filed: 1986-12-23
Abstract: PURPOSE:To obtain a recovered clock by providing guide pits arranged at a pitch being an integral number of multiple or one over an integral number of the period of a clock frequency of a digital signal to be recorded to a disk base so as to read the guide pits. CONSTITUTION:The ruggedness string 32 for tracking is constituted by the guide pit 321 provided at the period being an integral number of multiple of one over an integral number of the clock frequency of a digital signal to be recorded. The clock is recovered and the data is read by tracking the guide pit 321 constituting the rugged string 32 of the information recording section of the magneto-optical disk. Since the period of the pit 32 is sufficiently shorter than the period of the response frequency of the tracking servo in the magneto- optical disk, the rugged string 32 with respect to the tracking is handled similarly as the continuous guide slot 31. Since the signal of the rugged string 32 appears at all times as to the rotating period, the servo characteristic with excellent response and stability is obtained by controlling the servo so as to make the period constant.

Title: Pavement thickness controlling method for paving machine
Inventor: FUJITA MAKIO
IPC: E01C19/48
Filed: 1990-11-14
Abstract: PURPOSE:To flatly finish the surface of pavement by a method wherein a screed is controlled so that unevenness on the surface to be paved can be offset with the difference between calculated pavement thickness and preset target pavement thickness fed back. CONSTITUTION:Paving material is laid and rolled with a screed 5 as a vehicle 1 travels. A first and a second height sensor 13 and 14 measure the distances from the surface of the subbase and, at the same time, a gradient sensor 15 measures the tilt angle of a measuring arm 12, and a distance sensor 17 measures the distance of travel of the vehicle 1. All the measured results are outputted to a computing unit. One of the computing units calculates the average thickness of pavement out of values measured at a plurality of measuring points provided in succession on an already-paved surface, and obtains the difference between the average value and a target pavement thickness, and the calculated results are sent to the other computing unit. The other computing unit obtains the difference between a value measured by a third height sensor 19 and a target value for control that is obtained beforehand, and also obtains the extent of control for a pivot cylinder 8. The computing unit sends control signals to a solenoid valve, and thereby the cylinder 8 is expanded or contracted to control the screed 5.

Abstract: NEW MATERIAL:A polypeptide having an amino acid sequence expressed by the formula. USE:An antitumor agent. PREPARATION:For example, plaque hybridization is carried out from a rat chromosomic genetic library using a rabbit tumor necrosis factor(TNF)cDNA Pst I fragment as a probe to select a clone having a DNA capable of coding the rat TNF. The resultant phage DNA is cut out with a suitable restriction enzyme to provide a plasmid having a DNA fragment, capable of coding the TNF and integrated thereinto. The obtained recombinant plasmid is then inserted into a host, such as Escherichia coli. After transforming the host, the transformed host microorganism is subsequently cultured to separate the resultant product from the culture. Thereby, the polypeptide expressed by the formula is obtained.
