Title: Capacitance measuring method for capacitor
Inventor: TATE KUNIO
IPC: G01R27/26
Filed: 1990-02-03
Abstract: PURPOSE:To prevent a contact resistance from being contained in a measuring system by impressing a DC bias voltage on the measuring terminals and breaking down an oxidized film formed on the surface of outside electrodes of the capacitor. CONSTITUTION:The capacitance measuring instrument is kept in the state that an AC measuring voltage V and the DC bias voltage VB breaking down the oxidized film are superimposed beforehand. On the other hand, the measuring terminals 1, 2 are set (so as to be in) contact with the outer electrodes 4a, 4b of capacitor 3. When a switch S is put to the ON state, the AC measuring voltage V and the voltage VB are impressed on the terminals 1, 2. In a moment the switch S is put ON, a large current flows between the electrodes 4a, 4b of the capacitor 3 and the terminals 1, 2 and the oxidized film in the part being in contact with the terminals 1, 2 among the electrodes 4a, 4b is broken down to make the contact resistance almost negligible. Next, when the capaci tance of capacitor 3 is measured, the obtained value is expressed as a real capacitance value since the capacitance measurement is performed in the condi tion that the oxidized film is broken down.

Title: Pulse signal detector
Inventor: NISHIMURA TOMONORI
IPC: H03K5/19
Filed: 1994-02-24
Abstract: PURPOSE:To reduce a reception error rate when a transmitted signal subjected to pulse modulation transmitted at a prescribed period is received and detected. CONSTITUTION:A timer 1 provides an output of a gate trigger signal b1 after a transmission period T1 from the reception of a received signal a1, and a gate pulse generator outputs a gate pulse c1 with a gate pulse width T2 when receiving the gate trigger signal b1. An AND gate 3 receives the gate pulse c1 and a received signal a3 and provides an output of a detected signal d1. In this case, since a timing of a received signal a2 received with a period other than the transmission period T1 is deviated from an output timing of the gate pulse c1, the AND gate 3 provides no output of the detected signal. Furthermore, the received signal a2 is an invalid received signal because it is received on the way that the timer 1 receives the received signal a1 and counts the transmission period T1 and not counted by the timer 1. Then the AND gate 3 provides an output of detected signals d2, d3 by received signals a4, a5 detected with a period equal to the transmission period T1.
