摘要:
A seat device for use in a vehicle that can move through an opening of a vehicle between a loading and unloading position positioned outside the vehicle, where a passenger can load and unload as well as be seated, and a seating position positioned in the cabin of the vehicle, where the passenger can maintain a seated disposition. A securing member of the seat device can secure a wheelchair in a folded state to a side surface or a back surface of the seat. The wheelchair together with the seat can move from the loading and unloading position to inside the cabin of the vehicle, with the passenger in a seated position.

摘要:
An atomizing method for producing metal powder, including splitting molten metal in the vicinity of an exit of a nozzle by introducing the molten metal into a center of the nozzle, wherein gas is flowing through the nozzle. The split molten metal is then further split into fine particles by liquid ejected in an inverse cone shaped flow from a slit surrounding a lower side of the nozzle. The resulting powder is of fine size and spherical or granular shape, and is suitable for metal injection shaping.

The invention provides a nonmagnetic ceramic comprising 5% to 40% by weight of .alpha.-quartz and 5% to 60% by weigth of zinc silicate dispersed in 35% to 75% by weight of borosilicate glass as a matrix, the borosilicate glass having SiO.sub.2 and B.sub.2 O.sub.3 contents: SiO.sub.2 =70 to 90% by weight and B.sub.2 O.sub.3 =10 to 30% by weight. Using the nonmagnetic ceramic, multilayer ceramic inductors are obtained. When the ceramic is used as ceramic multilayer parts having an inductor section, it has a low dielectric constant and good characteristics in the high-frequency region, allows for low-temperature firing enabling the use of silver electrodes, prevents chip deformation and crack occurrence upon sintering, and provides a higher mechanical strength.

A method for producing a flexible metal laminate includes continuously thermocompression-bonding laminate metal foils to a resin film. The thermocompression-bonding step is conducted by placing a protection metal foil between a pressure surface of a heat and pressure forming apparatus and the laminate metal foils. When the protection metal foil is subjected to an abrasion resistance test, in which the protection metal foil is placed such that a matte surface of the protection metal foil contacts a plate material having a surface equivalent to the pressure surface and in which the matte surface is rubbed against the surface of the plate material by applying a load to a shiny surface of the protection metal foil and pulling the protection metal foil, a streak is found on the matte surface only in a case where the load is over 500 g per area of 76 mm×26 mm.

This invention has an object of providing a method for producing a multilayer substrate or an electronic part wherein decrease in the thickness has been enabled without causing the problem of insufficient strength or the like in the handling, as well as the electronic part. Such object has been attained by a method for producing a multilayer substrate or an electronic part comprising the steps of adhering a conductor layer to a transfer film, patterning the conductor layer to form a predetermined pattern, placing the transfer film overlaid with the patterned conductor layer on a prepreg so that the side of the conductor layer faces the prepreg, and then adhering the transfer film to the prepreg by applying heat and pressure and peeling the transfer film to produce the prepreg having the conductor layer formed thereon; and the multilayer electronic part produced by such method.

An electrostatic chuck for electrostatically clamping a semiconductor wafer while minimizing any plane temperature difference thereof has a dielectric layer joined to a metal plate and an inner electrode disposed in the di-electric layer. The dielectric layer has a raised outer rim disposed on an upper surface thereof along an outer peripheral edge thereof, and a plurality of protrusions disposed on the upper surface radially inwardly of the outer rim, the protrusions having upper surfaces for clamping the semiconductor wafer in direct contact therewith. The volume resistivity of the dielectric layer is 10.sup.9 .OMEGA.m or less, and Rmax (maximum height) of the clamping surfaces of the protrusions 5 is 2.0 .mu.m or less and or Ra (center-line average roughness) thereof is 0.25 .mu.m or less. The ratio of the total area of the clamping surfaces of the protrusions to the entire area of the upper surface of the dielectric layer is equal to or greater than 1% and less than 10%.
