Title: Antenna measuring method and measuring instrument
Inventor: NISHIMURA TOSHIO
IPC: H01Q3/26
Filed: 1996-10-31
Abstract: PROBLEM TO BE SOLVED: To calculate a non-measured excitation amplitude phase by fixing either a beam scanning angle or a frequency and measuring the excitation amplitude phase of each element antenna for each of a plurality of beam scanning angles that are not fixed or for each frequency. SOLUTION: A frequency is fixed, and the excitation amplitude phase of each element antenna is measured by an amplitude phase measurement means 11 at each beam scanning angle (θ=θ-n ,..., θ-1 , 0 deg., θ1 ,..., θn ) when receiving a signal. The excitation amplitude phase of each element antenna is measured by an amplitude phase measurement means 12 only when the beam scanning angle faces the front (θ=0 deg.) when transmitting a signal. The excitation amplitude phase of each element antenna in cases other than when the non-measured beam scanning angle faces the front is obtained, for example, by linear approximation, a second-order curve approximation, and a spline function using an amplitude phase calculation means 13, thus reducing the number of measurement parameters of the beam scanning angle when transmitting a signal and reducing a measurement time.

Title: Spectroscope
Inventor: NARA YASUO
IPC: G01J3/06
Filed: 1989-11-08
Abstract: PURPOSE:To facilitate driving, to reduce a slippage of an optical axis and to improve a wavelength resolution by disposing on the optical axis a pair of reflectors formed of a multilayer metal film and by rotating and moving straight them so that incident angles of light thereto be equal. CONSTITUTION:A multilayer film reflector 4 is supported rotatably around an axis vertical to an optical axis, i.e. the direction of advance of an incident light L1 and an incident angle theta is varied by the rotation of the mirror itself. It reflects a light of a wavelength component lambda satisfying the Bragg condition in the direction of the incident angle theta. With the rotation of the multilayer film reflector 4, a multilayer film reflector 5 is moved straight in parallel to the direction of advance of the incident light L1 so that the light reflected by the multilayer film reflector 4 may always fall thereon. At the same time, the multilayer film reflector 5 is rotated around an axis vertical to the optical axis so that the reflected light of the wavelength lambda from the multilayer film reflector 4 may fall thereon with the incident angle theta. According to this constitution, the light of the wavelength lambda is kept under the Bragg reflection condition also on the multilayer film reflector 5 and a monochromatic light of smaller wavelength dispersion is emitted. Accordingly, a wavelength resolution can be improved.

Filed: 1990-10-29
Abstract: PURPOSE:To widen the operating voltage range by selecting a gain of a crystal oscillation circuit depending on the oscillating state so as to reduce the oscillation start time thereby causing stable oscillation up to a low voltage.

Moreover, when the crystal oscillation circuit 1 is oscillated at a frequency higher than the set frequency, the gain switching signal 6 goes to a low level, the gain switching inverter 8 is inactivated, the gain of the crystal oscillation circuit l is decreased to bring abnormal oscillation to the normal oscillation. Thus, the gain of the crystal oscillation circuit 1 is kept high and the oscillation is attained at a low voltage.
