Title: Method and apparatus for inspecting airtightness of container especially automobile tank ventilating device, and diagnostic unit
Inventor: STEGMANN VOLKER
IPC: G01M3/32
Filed: 2002-06-24
Abstract: PROBLEM TO BE SOLVED: To improve a method and an apparatus for inspecting the airtightness of a container especially an automobile tank ventilating device so that diagnostic mistakes in airtightness levels are avoided. SOLUTION: Airtightness measurement is executed by giving positive pressure or negative pressure to the container (10) and measuring the change with time of the positive pressure or the negative pressure, and an reference measurement is similarly executed by a reference leakage part (36). By comparing the results of the airtightness measurement and the reference measurement with each other, the presence of non-airtightness in the container (10) is estimated in the method and the apparatus for inspecting the airtightness of the container (10) especially the automobile tank ventilating device. For avoiding diagnostic mistakes, it is proposed that the positive pressure or the negative pressure is measured by only one pressure sensor (40) in the airtightness measurement and the reference measurement.

Title: Hydrogen amount detector
Inventor: SHIMADA TAKEAKI
IPC: G01B7/16
Filed: 2002-06-25
Abstract: <P>PROBLEM TO BE SOLVED: To provide a hydrogen amount detector capable of accurately detecting a hydrogen amount even when the storage/release of hydrogen is repeated.  <P>SOLUTION: A resin layer 3b as a layer retaining a particle 2 of a hydrogen storage alloy is provided. The particle 2 causes a part of a surface of the resin layer 3b to be exposed so as to store hydrogen or emit hydrogen to the outside. A distortion sensor (distortion gauge) is provided on the resin layer 3b so as to detect a volume expansion when the particle 2a of the hydrogen storage alloy stores hydrogen. Since the layer retaining the particle 2a of the hydrogen storage alloy is a single layer, and the resin layer 3b stretches as the expansion is caused when the particle 2a of the hydrogen storage alloy stores hydrogen, sliding between the particles 2a is prevented. The same applies to the particle 2a when the hydrogen is emitted. Therefore, even after repeating the storage/release, the particle 2a of the hydrogen storage alloy is prevented from abrasion, pulverization and omission, thereby keeping capacity of the hydrogen amount detector uniform.  <P>COPYRIGHT: (C)2004,JPO

Simultaneously, the hole sections 15 are filled up. Then the insulating layers 21 and 22 are flattened by removing the surfaces of the layers 21 and 22 until the thicknesses of the layers 21 and 22 become the required ones.  <P>COPYRIGHT: (C)2004,JPO

Abstract: <P>PROBLEM TO BE SOLVED: To improve output efficiency and increase an operation speed without lowering the dielectric strength of a high-frequency MOSFET.  <P>SOLUTION: A P<SP>--</SP>-type impurity layer 12 is provided under N<SP>-</SP>-type impurity layers 2 and 3 which become a drain of the MOSFET. The P<SP>--</SP>-type impurity layer 12 is of the same P-type with a semiconductor substrate 1, but lower in impurity concentration than the semiconductor substrate 1. Further, the P<SP>--</SP>-type impurity layer 12 is so formed as to be joined with an N<SP>-</SP>-type impurity layer 2 and has a concentration profile such that the density of P-type impurities (the amount of included impurities) becomes larger with the distance from the junction part. Further, a depletion layer becomes easy to spread when drain voltage is impressed by setting the impurity concentration low nearby the junction part and thus the capacitance Cds between the drain and substrate is decreased to make the operation speed fast. In this structure, variation in capacitance Cds with the drain voltage is reducible, so a leak of electric power can be suppressed and the output efficiency is improved.  <P>COPYRIGHT: (C)2004,JPO
