Abstract: PROBLEM TO BE SOLVED: To measure a radar cross-sectional area of a measurement target with high accuracy by measuring only radar reflection characteristics of a reference target having a known radar cross-sectional area, which is to be compared with the measurement target, and executing calibration using a radiation signal from a signal source being a reference of calibration, when executing radar cross-sectional area measurement.SOLUTION: The reference target is suspended from a balloon in a position which is equally distant from transmission and reception antennas and is distant from the transmission and reception antennas differently from the balloon so that unnecessary things other than the reference target do not exist in the position, and the radar cross-sectional area of the reference target is measured. A reference signal transmission unit is attached to the balloon, and a signal from the reference signal transmission unit is used to calibrate a measurement value of the radar cross-sectional area.

Title: Spectral characteristic measuring apparatus and calibration method thereof
Inventor: ISHIMARU ICHIRO
IPC: G01J3/45
Filed: 2011-02-28
Abstract: PROBLEM TO BE SOLVED: To provide a spectral characteristic measuring apparatus which allows spectral characteristics to be precisely measured even in wide-field spectroscopic imaging, and a calibration method thereof.SOLUTION: In a measurement mode, light beams emitted from each bright spot of an object to be measured enter a first and a second reflection parts through a splitting optical system. An imaging optical system allows the light beams reflected therefrom to form an interference image. The movement of the first reflection part elongates or contracts the relative difference in optical path length between the first and the second reflected light beams proceeding from the splitting optical system through the first and the second reflection parts toward the imaging optical system. An interferogram of each bright spot of the object to be measured is obtained based on the light intensity change of the interference image on this occasion. In a calibration mode, the light beams emitted from the bright spot with a prescribed wavelength λ enter the splitting optical system so as to form a plurality of interference images corresponding to the bright spot. The movement distance of the fist reflection part corresponding to one cycle of the light intensity change is obtained based on the light intensity change on this occasion. The installation angle of the first reflection part is obtained from the wavelength λ of the bright spot, the movement distance of the first reflection part, and the field angle θ of the interference image.

Title: Game machine
Inventor: TSUGE KEN
IPC: A63F7/02
Filed: 2011-03-11
Abstract: PROBLEM TO BE SOLVED: To provide a game machine having a reduced load of control board processing, when a fraud is committed using a radio wave.SOLUTION: Even when an unauthorized radio wave having repeated H and L signals with a short cycle length of 4ms, is applied, once a CPU of a main controller sends a fraud signal to a sub unified controller (fraud flag on), a fraudulence clear signal (fraud flag off) is not sent during a time T1, so that the load of processing the CPU of the main controller is reduced. The sub unified controller having received the fraud signal notifies of fraudulence once every time receiving one fraud signal, so that the load of processing a CPU of the sub unified controller is also reduced. Even when the fraudulence clear signal is received from the main controller, notification operation is extended until a time T2 elapses, and thus even when the unauthorized radio wave is applied for a short time (e.g. one second), the notification operation is executed longer than the length of the time T1 and the time T2, and notification effect is increased.
