Title: Optical fiber abutting device
Inventor: SUZUKI ISAO
IPC: G02B6/40
Filed: 1999-01-28
Abstract: PROBLEM TO BE SOLVED: To improve the operation efficiency without increasing the cost when end surfaces of optical fibers are made to abut against each other and optically coupled with each other with low loss. SOLUTION: A couple of optical fibers 21 and 22 are set in a V groove 11 formed on a V-groove block 10 and aligned with each other. A matching plate 12 which has excellent light transmissivity and a specific refractive index is arranged halfway along the length of the V groove 11 and the end surfaces of the optical fibers 21 and 22 are made to abut against each other across the matching plate 12. The matching plate 12 is arranged in a groove 13, which is filled with matching liquid 14, then the matching liquid 14 is present between the end surfaces of the optical fibers 21 and 22 and matching plate 12, so that no air layer is formed between them. Consequently, no Fresnel reflection is caused on the end surfaces of the optical fibers 12 and 22 and low-loss coupling is actualized.

Title: Arithmetic circuit
Inventor: MUKOGASA YUKIO
IPC: G05B11/36
Filed: 1989-02-01
Abstract: PURPOSE:To reduce occurrence of offsetting by providing a 2nd arithmetic circuit equivalent to a 1st arithmetic circuit causing offsetting and feeding back the output signal of the 2nd arithmetic circuit to the input side of the 1st arithmetic circuit. CONSTITUTION:While the output signal of an operational amplifier 2B is not fed back to the point D on the input side of another operational amplifier 1A, a voltage equal to the offset voltage produced at the point A on the output side of the amplifier 1A is produced at the point B on the output side of the amplifier 2A. The voltage produced at the point B is fed back to the point D on the output side of the amplifier 1A after it is amplified by the amplifier 2B. Therefore, occurrence of offsets at the point A can be reduced, since operations similar to those performed when a command value 11 is made larger by the voltage value at the point C are executed.

Title: Device for cooling rolled wire rod through adjustment from rolling temperature
Inventor: YOHAN GUROOTEPASU
IPC: C21D9/573
Filed: 1982-02-15
Abstract: Apparatus for cooling rolled wire rod consists of a first part which guides the wire rectilinearly and cools it with water, a turn-laying unit which forms the wire into turns and lays the turns in staggerred disposition on a continuously running conveyor, and a second part comprising the conveyor which allows passage of an approximately vertically directed stream of air to the turns and conveys the wire turns to a coil forming station which collects them. In order to provide substantial adaptability to various cooling requirements by means of simple and inexpensive conversion, the two parts are composed of a plurality of modules of the same modular length or an integral multiple of the modular length. A base frame carries the modules and the turn-laying unit is fixed on the base frame in a longitudinally displaceable manner. Thus, the lengths of the first and second parts can be changed, and individual modules or groups can be replaced.

Title: Oceanographic acoustic tomographic data analyzer
Inventor: ARAYA TOMIO
IPC: G01S7/526
Filed: 1997-02-04
Abstract: PROBLEM TO BE SOLVED: To easily and accurately track the peak of received signal data by finding the propagating time of the maximum signal peak of received signal data obtained at every receiving time as the representative propagating time at each receiving time. SOLUTION: Received signal data measured at regular time intervals (of, for example, three-hour intervals) are successively inputted to a received signal data memory 1 at every observation from a data input-output section 11. Of the received signal groups which necessarily exist in the received signal data and are most slowly propagated in the shortest distance, the propagating time of the peak having the highest signal level is found as the representative propagating time of the signal data at every receiving time. The variation between the received signal data at reference receiving time and those at another receiving time is generated by using the representative propagating time and the reception starting time is shifted so that the variation may become zero.  Therefore, the correspondence between the received signal data of a transmitted wave at reference time and those of a transmitted wave at another time becomes clear.

Title: Electromagnetic flowmeter
Inventor: KURITA YOSHIO
IPC: G01F1/60
Filed: 1978-02-28
Abstract: PURPOSE: To eliminate the need for remedy against evolution of heat such as of mounting a large heat sink or the like by selecting the period when exciting current is flowing shorter than the period when no exciting curent flows.  
     CONSTITUTION: First, a semiconductor switch 3 is controlled by a driving pulse P 1  and when P 1  is ON, the current 1 from a constant current source 2 is flowed to an exciting coil 5. When P 1  is OFF, no current is flowed to the exciting coil 5. Hence, the exciting current I w  having the ON period τON and the OFF period τOFF is supplied to the exciting coil 5. Here, if the ON period τON when the exciting current is flowed is selected shorter than the OFF period τOFF when it is not, then the mean value of the exciting current becomes 1/4 that of conventional cases of τON =τOFF, thus the power consumption as the flowmeter decreases and in addition, the joule heat produced in the switching element and exciting coil 5 decreases accordingly.
