Title: Apparatus and method for measurement of at least one kind ofvolatile component in gas sample or liquid sample
Inventor: UIRIHERUMU SHIMON
IPC: C05F17/02
Filed: 1991-04-05
Abstract: PURPOSE: To measure a volatile component in a gas or liquid sample in a short time with a simple and long-life device by directly forming a gas-permeable film, and supporting it mechanically with the sensor. CONSTITUTION: When a sample gas or liquid is injected from a hole 11 into a chamber 5 of a device main body, 4, it comes into contact with a gas- permeable film 3 having a large surface, and a volatile component in the sample permeates the film 3 and then comes into contact with an optical sensor film 1. Then, the light from a light source 7 is maid to enter the chamber 5 through a capacitor 8 and a light-transmissive plate 6, and after the film 3 and the sensor film 1 is irradiated with it, it is emitted from a light-transmissive plate 2, and then reflected on a concave diffraction optical grating 9 and introduced to a detector 10, for detecting optical characteristics of volatile component.  With this configuration, since there is no protective element between a sample and the film 3 surface, the effective surface of film 3 is not covered, and since a solid/semi-solid sensor mechanically supports the film 3, the film 3 can be thinner. Thus, after contact between the sample and the film 3, a volatile component passes through the film 3 without delay, so response time is shortened.

Title: Non-turning universal direction wheel
Inventor: TERATANI KIYOSHI
IPC: B60B19/00
Filed: 1998-02-17
Abstract: PROBLEM TO BE SOLVED: To set two rotary shafts to make a right angle with each other by making the part of a wheel outer circumferential part originally to be mounted with a tire to be a circular shaft, and alternately continuously arranging rollers and cushioning materials rotating in the direction perpendicular to the rotating direction of the wheel on this shaft. SOLUTION: For giving steering ability to a fixed type wheel, in addition to the ordinary moving direction, wheels capable of moving in the quite different direction are required. Then, rollers 3 are arranged setting the edge end part of an ordinary fixed type turning wheel to be the shaft. In short, the shaft 2 of the turning wheel and the shaft of the rollers 3 are made a right angle with each other. When the turning wheel is operated in the fixed advance direction, rotating operation is not generated in the rollers 3, but when force perpendicular to the fixed advance direction is given to the turning wheel, the turning wheel can not be operated and the rotary motion of the rollers becomes maximum.  In short, force generated in the area in the square direction constituted by the shaft 2 of the turning wheel and the shaft 5 of the rollers, namely, vector is divided into force to the turning wheel and the rollers.

Title: Second converter for receiving satellite broadcast
Inventor: UNNO TORU
IPC: H04N5/46
Filed: 1995-03-30
Abstract: PURPOSE: To receive an excellent BS broadcast program by making both a high speed response operation and a weak electric field operation of a PLL/ demodulation circuit proper. CONSTITUTION: An IF filter 12 extracts a broad band IF signal S2 and a narrow band IF signal S3 from an IF signal Sl amplified by an IF amplifier 11. Either of the signals is selected by an IF band width changeover circuit 13 and the selected signal is given through an IF amplifier 14 to a PLL/FM demodulation circuit 15, in which the signal is demodulated. A lock range width changeover circuit 16 applies a voltage to set a wide lock range width to a variable amplifier of a pre-stage of a phase comparator being an internal circuit to the PLL /FM demodulation circuit 15 in the normal operation and applies a voltage to set a narrow lock range width when a weak electric field switching control signal S19 is received.  Furthermore, a time constant corresponding to a high speed response is set to an externally mounted resistor and capacitor (loop filter time constant changeover circuit 17) of a loop filter of the PLL/FM demodulation circuit 15 in the usual operation and when the weak electric field switching control signal S19 is received, a time constant for the weak electric field operation is set (switched).

Title: Electric terminal in jet generator by electric field
Inventor: YABE AKIRA
IPC: F28F13/16
Filed: 1986-03-31
Abstract: PURPOSE:To improve the heat transfer performance by providing a meshed electric terminal with differently sized meshes. CONSTITUTION:When a high voltage is applied between a meshed terminal 4 and an area terminal 1 to form an electric field, lines of electric force act between the terminals 4, 1 to form an uneven electric field in which the electric field is strong near the meshed terminal 4 and weak near the area terminal 1. The electric field in small-sized mesh zones B, C becomes stronger than that in a large-sized mesh zone A. As a result, jets to liquid 3 are generated from the small-sized mesh zones B, C to the large-sized mesh zone A. Because the electric terminal materials 5 are close to each other in the small-sized mesh zones B, C, the electric field there becomes stronger compared with a case where the same voltage is applied to a large-sized mesh. The pressure of the liquid 3 becomes higher all the more to make the pressure gradient greater and the jet speed greater as well. Because the jet speed increases, the heat transfer performance of a heat exchanger can be improved.

Abstract: PURPOSE:To obtain desired driving speed quickly even when slip is generated on a sliding surface by mounting the change-level detecting means of driving speed and resetting the integrating means of a speed deviation when the rate of change of speed exceeds a set level. CONSTITUTION:A differential computing element 21 arithmetically operates a speed deviation by a speed command value and the detecting speed value of a speed detecting means 26, an integrating computing element 22 having a reset function conducts the time integration of the speed deviation, and a proportional computing element 23 multiplies a value as the result of the time integration by an arbitrary constant and arithmetically operates the value.

Abstract: PURPOSE: To enhance the reliability of the composite calculation system by giving the periodical checking to the data transfer between the arithmetic devices connected to the common bus in order to monitor whether the transfer is normal or not.  
     CONSTITUTION: Unit check codes 21W23 are sent to common bus 11 periodically from arithmetic unit 12A and then received at arithmetic unit 12B. And immediately unit answer data 31W34 are sent to bus 11. When receiving the answer data by the next sending period after sending the unit check code, data transfer check function 15A checks the agreement between code 33 and 32. And when the agreement is obtained, the normal transfer is decided for the transfer of unit 12B decided by number 34 to then memorize the fact of reception. The preceding reception fact is checked in the next sending period, and the next check data is sent only when the reception is detected. And the next check data is sent after the warning is given to the fact of nonreception. In such way, the arithmetic unit is monitored, thus ensuring dealing of a large amount of the data with a high speed as well as high reliability.
