Title: Gas-leakage detecting apparatus
Inventor: NANBA MITSUO
IPC: G01M3/00
Filed: 1990-06-07
Abstract: PURPOSE:To make it possible to detect leakage at the upstream side of a flow rate sensor during the use of of a pilot flame and the like by providing a pressure sensor a the upstream of a cutoff valve and a memory means for a pressure fluctuation signal during the use of the pilot flame, and performing the electrical connections and the like of the means and flow-rate and pressure-signal transmitters. CONSTITUTION:When a gas meter 12 of a flow rate sensor detects the flow of gas, a flow-rate-signal transmitter 15 transmits a flow rate signal. When a pressure sensor 11 which is provided at the upstream side of a cutoff valve 10 detects the fluctuation in gas pressure, a pressure-fluctuation transmitter 14 transmits a pressure-fluctuation signal.A pressure-fluctuation-pattern memory part 16 stores the pressure-fluctuation signal when a pilot flame is used. Then, in a microcomputer 13, the flow rate signal is compared with the pressure fluctuation signal, and the pressure fluctuation memory of the memory part 16 is compared with the measured pressure fluctuation signal when the pilot flame is used. The patterns when the pilot flame is continuously used are compared. When the patterns disagree and when the flow rate signal is not inputted in the case of the input of the pressure fluctuation signal, a leakage signal is transmitted as the occurrence of the gas leakage at the upstream side of the meter 12.

Title: Array antenna receiver and phase rotation amount correction method for reception signal
Inventor: HIRAMATSU KATSUHIKO
IPC: H01Q3/36
Filed: 1998-05-28
Abstract: PROBLEM TO BE SOLVED: To correct a phase rotation amount so that an input signal to an adaptive array antenna reception circuit keeps a phase difference at antenna terminals. SOLUTION: A phase control variable table 119 (120) uses a gain denoting a received gain control signal Sg1 (Sg2) as an argument to provide a phase control signal Sc denoting a corresponding phase rotation amount to a vector multiplication circuit 117 (118). The vector multiplication circuit 117 (118) rotates a phase of an in-phase component S13 (S23) and a quadrature component S14 (S24) of an antenna 2 in the opposite directions. Thus, a phase rotation amount by a reception amplifier is corrected so as to keep an input signal for each antenna a phase difference at antenna terminals.

Title: Optical measuring instrument
Inventor: YOSHIZUMI KEIICHI
IPC: G01B9/02
Filed: 1985-07-05
Abstract: PURPOSE:To prevent the length of an optical path from varying and an error in measurement from occurring by moving measurement light incident on an objective at right angles to the optical axis. CONSTITUTION:The measurement light and reference light which have frequencies F1 and F2 are separated by a polarizing prism 12. The measurement light F1 is converged on a mirror 5 and reflected, and reflected totally by a polarizing prism 3 to enter the objective 2, so that the light is converged on the surface 1 of a body to be measured. The reflected light from the object body surface 1 is reflected totally by the polarizing prism 12 to reach a photodetector 18. The optical path of the reflected light tends to shift according to the inclination of the object body surface 1, but that is detected by a four-division detector 14 and a condenser lens 4 is moved in a direction Y-Z to shift the position of incidence on the objective 2, thereby controlling the reflected light so that the light travels backward through the same optical path at any time. This inclination correcting means allows the measurement light which is reflected invariably without reference to the inclination of the object surface and the reference light to be superposed on the photodetector 18 and interfere with each other, generating a beat signal. Consequently, neither the optical path length of the measurement light nor the measurement position varies, and there is therefore no error in measurement generated.
