IPC: G01R31/02
Filed: 2000-03-24
Abstract: PROBLEM TO BE SOLVED: To provide a device and a method for inspecting substrates in a short inspection time capable of being applied to a high-density substrate. SOLUTION: A computer 44 transmits instructions to a switch part SW1 to turn only a switch SW1a on and to turn other switches off. By this, only a probe 40a is connected to a signal source 46, and other probes are not connected to the signal source 46. By this, the printed pattern 34a of a substrate 32 is selected to be an object of inspection. When the switch SW1a is turned on, an equivalent circuit is closed to pass a current (i). After a voltage Vx is amplified by an amplifier, a maximum value is detected and held by a peak hold circuit. The peak hold circuit is provided with a D/A converter, and the digitized maximum value is transmitted to the computer 44 to determine the state of continuity of the printed pattern 34a of the substrate 32 on the basis of the maximum value.  An input voltage Vx to the amplifier displays the maximum voltage approximately simultaneously with the turning-on of the switch SW1a.

Title: Device and method for radio communication
Inventor: NAKANO KIICHI
IPC: H04L27/20
Filed: 2000-03-27
Abstract: PROBLEM TO BE SOLVED: To provide radio communication equipment capable of transmitting a wave to be modulated having relatively a small number of frequency errors in the case of receiving a signal from the opposite party. SOLUTION: A correction quantity extracting part RE2 detects a deviation angle from a phase of a reference signal point of phase information included in a received signal and decides correction quantity corresponding to the deviation angle. Because a transmitting side converts transmission data to be a transmission object to the opposite party into a set of amplitude data corresponding to a signal point, the transmitting side adds the decided correction quantity to the phase of the signal point shown by the set of amplitude data and performs correction. A carrier for transmission is modulated by using a set of the corrected amplitude data and transmitted to the opposite party. Thus, the wave to be modulated whose frequency changes in accordance with the frequency accuracy of the opposite communication party can be transmitted.
