Title: Method for detecting underground gas leaking position
Inventor: SAITO TAKESHI
IPC: G01M3/04
Filed: 1993-07-08
Abstract: PURPOSE:To provide a method for detecting underground leaked gas. CONSTITUTION:A specific amount of gas is sent from a point A in a center part into the ground and then gas concentration is measured at points B and C located at both sides to confirm that gas leakage points are located between the points A and B and then a specific amount of air is sent from the point B into the ground and then the gas concentration at the point A is measured to measure and record the rising time of gas concentration, namely T1, and then a specific amount of air is similarly sent from the point A to measure and record a rising time T2 of gas concentration, thus obtaining a leakage point from an equation LX(T1)/(T1+T2) from the point A with the distance between the points A and B being equal to L. The leakage position of gas can be determined by repeatedly sending air. measuring gas concentration, measuring the rising time of gas concentration, etc., at the point A at the center part and at the points B and C located at both sides. When it is found that leakage occurs at two inspection regions, namely between the points A and B and between the points A and C, the same can be repeated for each inspection region, thus determining a leakage position.

IPC: H04B10/572
Filed: 1992-06-26
Abstract: PURPOSE:To obtain a circuit wit a wide dynamic range without deterioration in the band distortion characteristic by allowing an APD to keep a constant output level, changing a multiplication factor only for a specific range and varying a gain of a variable gain amplifier circuit for another range. CONSTITUTION:A voltage control circuit 3 controls a multification factor of an avalanche photodiode(APD) 1 by varying a voltage applied to the APD 1 to vary the multification factor for range in which an output level of the APD 1 used to convert an optical signal into an electric signal is kept constant and its band distortion characteristic is not deteriorated. In this case, the gain of the variable gain amplifier circuit 7 is kept constant. The multification factor is kept constant by the voltage control circuit 3 for a range of a maximum light receiving level from an upper limit of compensating the band distortion characteristic by the APD 1 and a constant output level without distortion is obtained by the variable gain amplifier circuit 7. With an optical input larger than the maximum light receiving level, a protection circuit 6 is operated to reduce the multification factor and for a range below the lower limit for compensating the band distortion characteristics, the multification factor is kept constant.

IPC: H02H9/06
Filed: 1981-10-23
Abstract: A filtering and protection circuit (10), for use in a power distribution system including live, neutral and ground conductors (L, N, G) and having a circuit-breaking device (12) in one of the conductors, includes transient protection devices (16) connected from a common circuit point (18) to the respective conductors (L, N, G) of the system. Failure (shorting) of any one of these transient protection devices can bring about actuation of the circuit-breaking device (12). The protection devices may comprise silicon diode transient voltage suppressors suitable for high voltage applications, clamping at a rated voltage in one direction and having a forward diode characteristic in the other direction. Each such suppressor may be paired with a parallel capacitor (22) protected by its diode from surges or transient voltages. Such pairing of suppressors and parallel capacitors can enable polarized capacitors to be used in AC circuitry.

Title: Heat radiation construction of coil
Inventor: ITOU RIYOUICHI
IPC: H01F5/00
Filed: 1983-09-14
Abstract: PURPOSE:To enable preventing damage of an adhesive layer even in rapid change of temperature by integrating a coil and a radiation member with the adhesive layer which contains addition polymer type silicone rubber and inorganic bulking agent. CONSTITUTION:An adhesive layer which integrates a coil 1 and a radiation member 2 is formed with a heat conductive composition which includes addition polymer type silicone rubber and inorganic bulking agent. The composition has great bonding strength against metal and ceramics and elasticity even after hardening so it can follow expansion and contraction due to rapid change of temperature. The inorganic bulking agent has also smaller coefficient of thermal expansion than that of silicone rubber and it enables the coefficient of thermal expansion of the adhesive layer to become nearer to that of metal or ceramics than the case without the bulking agent whereby the following ability against thermal impact can be made greater. Consequently, it is possible to prevent damage of the adhesive layer which integrates the coil and the radiation member under the condition of rapid change of temperature.

Filed: 1999-06-17
Abstract: PROBLEM TO BE SOLVED: To make a seal obtained by machine engraving more easily discriminable and eliminate the possibilities that an identical impression might be used by another person and thereby allow the user to use the seal without anxiety. SOLUTION: In the seal whose printing face is machine-engraved, a check section 1 is provided which permits a part of its printing face R to be optionally machined by the upper. This check section 1 is formed along the contour of the printing face P and in such a manner that the section 1 is aligned in parallel with characters of the printing face P. In addition, the check section 1 is formed of a plurality of protuberances 1A provided on the printing face P and these protuberances 1A are partially removed by the user to change the impression. A plurality of the protuberances 1A spaced from each other thus form the check section 1 and the impression is changed by partially enlarging the space between the protuberances 1A upon the option of the user.
