Abstract: <P>PROBLEM TO BE SOLVED: To stably generate ozone and stably conduct the inverter control.  <P>SOLUTION: A pulse width of an AC output voltage V1 of an inverter 1 is subjected to the PWM control in order to make an injection current I injected into an ozone generating tube 3 agree with a current command value I* prescribed according to a power command value Q* and the control is conducted to generate a plurality of pulses in one cycle of a frequency of a load voltage V2. With such a constitution, as a ripple corresponding to an ON/OFF frequency following the pulse width control appears in the injection current I, if a gap voltage VG is close to a discharge voltage average value Vz, a period while the gap voltage VG is sufficiently higher than the discharge voltage average value Vz and a period while the gap voltage VG is sufficiently lower than the discharge voltage average value Vz are produced by the ripple component included in the gap voltage VG. As these periods are a period while the discharge is surely conducted and a period while the discharge is never conducted respectively, the discharge state does not stay in a period while the existence of the discharge is uncertain, so that the stable discharge can be conducted.  <P>COPYRIGHT: (C)2003,JPO

Title: Sound pressure detection method and microphone thereof
Inventor: NAKAMURA KENTARO
IPC: G01H9/00
Filed: 2002-02-04
Abstract: <P>PROBLEM TO BE SOLVED: To provide a microphone which can improve a directivity without making a construct large-scale.  <P>SOLUTION: Either of a measurement optical path of an interferometer and a reference optical path is formed on at least a part of a surface which a wave front of a detected sound wave enters in phase.

Firstly, when the detected sound wave enters either of the optical path, a refractive index of the optical path changes, thereby resulting an interference signal at the interferometer. If no change occurs in the geometric optical path difference between the measurement optical path and the reference optical path at this time, the interference signal indicates the change of the refractive index in either of the optical path, i.e., the detected sound wave.  <P>COPYRIGHT: (C)2003,JPO

IPC: H01B11/02
Filed: 2002-02-06
Abstract: <P>PROBLEM TO BE SOLVED: To provide a transmission cable of improved productivity, where propagation delay speed difference within a pair and between pairs is reduced even if a plurality of pairs of signal line pair is bundled.  <P>SOLUTION: A pair of signal wires 5 constitutes a signal wire pair 7, and two signal wire pairs 7 are unit-twisted to constitute a signal wire pair unit 3 having almost a circular shape in the cross section, thus a collective cable is constituted. Since the signal wire pair unit 3 has almost a circular shape in the cross section, the tension is almost evenly applied to each of the signal wires 5 when twisted. So it is easily worked into a signal cable 1 with equal- length of signal wire pairs 7, resulting in stable and improved electric characteristics of the transmission cable 1. Since each signal wire pair 7 has an equal length, the skew characteristics within a pair and between pairs decreases.  <P>COPYRIGHT: (C)2003,JPO
