摘要:
A polyvinyl chloride resin having an average particle diameter of not less than 150 &mgr;m and porosity at 31-1,011 psi of not less than 0.15 cc/g is suspended in an aqueous medium and chlorinated by blowing gaseous chlorine into the aqueous suspension. In this way, the floating resin formation during chlorination can be prevented and a chlorinated polyvinyl chloride resin excellent in free flow property and showing good resistance to initial discoloration and good thermal stability in heating and molding processes can be produced.

A contact probe having a plunger; a top contacting member which is provided at a tip end of the plunger and is brought into contact with an electrode of a semiconductor device; a bottom contacting member which is brought into contact with an electrode of a testing board; and an elastic member for urging the top contacting member and the bottom contacting member in opposite directions away from each other. The plunger is formed into a cylindrical shape and includes a through-hole which penetrates through the plunger in an axial direction thereof. The top contacting member includes a plurality of mountain-shaped sharp portions at a tip end thereof, and each of the sharp portions is asymmetrical with respect to a straight line that passes through a peak of the sharp portion and extends along an axial direction of the plunger, and is bent toward a center line of the plunger.
摘要:
It is an object of the present invention to provide a fuel cell electrolyte membrane reinforced with a porous substrate which has excellent durability and in which the amount of cross leakage as a result of chemical deterioration of electrolyte membrane components due to the presence of peroxide and/or radicals is particularly reduced. The present invention relates to an electrolyte membrane for a fuel cell comprising a polyelectrolyte, which contains a porous substrate and a radical scavenger dispersed in the polyelectrolyte.

摘要:
An input apparatus includes a display device and an input device. The display device displays a first hierarchy icon, a second hierarchy icon, which is in a state where setting options corresponding to characteristics of the first hierarchy icon are displayed to be arranged in an annular shape, and a pointer. The input device integrally includes a rotation device, a joystick device, and a determination device. The display device moves the pointer in a direction corresponding to an operation direction and changes the first hierarchy icon to the second hierarchy icon,wherein the display device shifts the options in the annular shape in a rotation direction. The determination device determines setting of the option, which is positioned at a predetermined position by a predetermined operation of the operator among the options, as the setting corresponding to the characteristics of the current first hierarchy icon.

Provided is an electric connecting apparatus configured to dissipate heat generated from a contact itself via an insulating plate, a metallic enclosure, and a printed wiring board. The electric connecting apparatus includes at least a housing configured to accommodate multiple contacts. At least part of the housing is made of a material having high heat conductivity. The multiple contacts are arranged linearly in at least one row. The multiple contacts are in abutting contact with the at least part of the housing via at least an insulating member made of an electrically insulative material having high heat conductivity.
摘要:
One aspect of the present invention provides a semiconductor light-emitting device improved in luminance, and also provides a process for production thereof. The process comprises a procedure of forming a relief structure on the light-extraction surface of the device by use of a self-assembled film. In that procedure, the light-extraction surface is partly covered with a protective film so as to protect an area for an electrode to be formed therein. The electrode is then finally formed there after the procedure. The process thus reduces the area incapable, due to thickness of the electrode, of being provided with the relief structure. Between the electrode and the light-extraction surface, a contact layer is formed so as to establish ohmic contact between them.
