IPC: B60J1/17
Filed: 2002-11-26
Abstract: <P>PROBLEM TO BE SOLVED: To provide a security system of a power window device capable of ensuring further reliability.  <P>SOLUTION: In this security system 10, when an abnormality of glass is detected by a sensor 16, confirmation and determination are further performed in an operation switch part 14 on the basis of a pulse signal (glass position detection signal) from a motor part 12. The confirmation and determination comprise confirming that the glass is located in a prescribed range (e.g., closed position) and then driving the motor part 12 to raise the glass. Since the glass never exceeds the prescribed range when the abnormality signal from the sensor 16 is a false report, the false report can be determined. When the glass is raised over the prescribed range, the glass is laid in, for example, a cracked state, and the true abnormality is determined. When the true abnormality is determined in the confirmation and determination, a determination signal is transmitted to an ECU 18, and the ECU 18 performs a prescribed alarm operation.  <P>COPYRIGHT: (C)2004,JPO

Title: METHOD FOR FORMING ELECTRODE WITH LOW CONTACT RESISTANCE ONTO n-TYPE CONDUCTIVE ZINC OXIDE
Inventor: OHASHI NAOKI
IPC: C23C14/24
Filed: 2002-12-03
Abstract: <P>PROBLEM TO BE SOLVED: To form an electrode with low contact resistance onto zinc oxide which is useful as an electronic material including an electric resistor and a sensor material.  <P>SOLUTION: The method for forming the electrode comprises heating/vaporizing indium metal and fixing the vapor on the surface of the zinc oxide. In the above step, direct current plasma is used in particular for the purpose of avoiding increase of contact resistance by oxidation of indium metal, to improve adhesiveness of vapor deposited indium. The method further comprises stopping generation of the direct-current plasma after the vapor deposition of the indium metal, and without breaking the vacuum, preferably vapor depositing a noble metal on the indium metal electrode so as to form a film for preventing the oxidation. Because the film acquires higher adhesiveness of the indium metal than that by pressure bonding or normal vapor deposition, the film realizes a more stable ohmic property and lower resistance.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
