摘要:
A method of exposing a peripheral part of the wafer is used for a fine pattern formation process in the processing of ICs, LSIs and other electronic elements, to remove, in a development step, an unnecessary portion of a photoresist coated on a semiconductor substrate, typically a silicon wafer, or a substrate consisting of a dielectric, a metal or an insulator. A peripheral part of the wafer is exposed to light led by an optical fiber light guide. The same area is exposed to light at least twice in a predetermined time interval. The illumination intensity of light in a wavelength range necessary for the first exposure is set to be lower than that for the second and following exposures. In the first exposure, the wafer may be held in a heated state.

A mobile station receives radio waves from all signposts through the positioning channels while making communications using the voice channels. The signal levels of the radio waves thus received are subjected to comparison, so that a zone switching request is made to a signpost with the highest signal level, whereby a mobile station can make communication through that signpost which covers the zone where the mobile station is located, even while traveling. The positioning channels are so set that the frequencies assigned to the signposts are switched every frame in a time series mode, and none of the signposts transmit one and the same frequency at the same time. Therefore, the mobile station can receive radio waves from all the signposts without signal interference (which may be caused when a plurality of stations transmit signals equal in frequency). In the system of the invention, the transmission zones of adjacent signposts overlap each other. When a zone switching request is made, a mobile station can therefore make communications with both of the signposts; that is, the switching of zones can be positively achieved.

Ultraviolet radiation process applied to manufacture semiconductor devices in order to enhance the thermal stability of the photoresist film on semiconductor wafers.A method, in ultraviolet radiation process, enabling effective treatment of the developed positive photoresist image employing ultraviolet irradiation by preventing the deformation of the developed positive photoresist image which is caused by exposing it to high ultraviolet radiation at the beginning of exposure. This method employs ultraviolet irradiation, in which the developed positive photoresist image placed in gas of a lower atmospheric pressure is exposed to ultraviolet radiation of low intensity at the beginning of exposure, and then exposed to ultraviolet radiation, the intensity of which increases little by little or in steps.

The present invention relates to food products containing a novel alpha-glycosyl ginsenoside wherein one or more alpha-glucosyl moieties are bound to ginsenoside residue, and a process for producing the food products. Such alpha-glycosyl ginsenoside is obtainable by subjecting an aqueous solution of ginsenoside and an alpha-glucosyl saccharide to an alpha-glucosyl transferase.

Provided is a nonaqueous electrolyte secondary battery 10 which, in cases where separators 70 each having a heat-resistant layer 74 on only one face thereof are used, has an excellent thermal stability and thus a higher safety and reliability when the battery 10 reaches a high temperature. Such a nonaqueous electrolyte secondary battery 10 includes a positive electrode 30 in which a positive electrode active material layer 34 is provided on both faces of a positive electrode current collector 32, a negative electrode 50 in which a negative electrode active material layer 54 is provided on both faces of a negative electrode current collector 52, at least two separators 70 each having a heat-resistant layer 74 on one face of a base material 72, and an electrolyte. The nonaqueous electrolyte secondary battery has an electrode assembly 20 in which the positive electrode 30 and the negative electrode 50 are stacked on top of one another with the separators 70 interposed therebetween. The at least two separators 70 are disposed in such a way that, for each separator, the heat-resistant layer 74 is positioned on the same side with respect to the base material 72 in the stacking direction.

A disk brake includes a caliper body having a cylinder portion (25) with a cylindrical shape. The cylinder portion (25) has a bore (30) with a bottom (34) formed by integrally joining together an opening peripheral edge (98) at the bottom side of the cylinder portion (25) and a bottom cover member (92) to be fitted to the opening peripheral edge (98) through friction stir welding. The bottom cover member (92) has a disk shape and is friction-stir-welded along the outer periphery thereof. The terminating point of the friction stir welding is within the boundaries of the bottom cover member (92).

A disk brake and a method of making the disk brake capable of improving the efficiency of manufacturing a caliper. A bottom portion (41) of a bore (40) is formed by integrally welding an opening surrounding portion at the bottom portion side of a cylinder portion (35) and a bottom cover member (92) fitted to the opening surrounding portion by friction stir welding. The bottom cover member is formed into a disk shape, and provided with a protrusion (68) at one surface side facing the interior of the bore. An inflow hole (58), for a supply of a fluid pressure into the bore, is formed within the range of the protrusion to establish communication between an interior surface (71) of the protrusion and an outer surface (63) of the bore.

A caliper body of a floating-type disk brake includes a cylinder having a cylinder bore into which piston pressing brake pads are disposed against a disk rotor, a bridge extending from the cylinder part including a through-hole, and a claw part formed on a leading end side of the bridge and disposed opposite to the cylinder part. The caliper body of the floating-type disk brake is made in a mold with sprues provided in at least two places spaced apart from each other in a disk rotor circumferential direction on a region corresponding to the claw part. Molten metal is poured from the sprues in at least two places of the mold, and starts to solidify from a side of the cylinder part.

A shim plate is provided at the rear side of a friction pad to abut annular contact parts of pistons. The shim plate is provided with first and second one-side cut portions and at a position corresponding to the annular contact part of a disk rotational entrance-side piston, for example, so that the area of contact between the shim plate and the annular contact part is larger at the disk rotational exit side than at the disk rotational entrance side. The first and second one-side cut portions and have four contact ends at which the peripheries of the cut portions and the annular contact part intersect each other. At least two of the four contact ends are provided on the disk rotational entrance side with respect to the diametrical center of the piston.

A water-lifting pump apparatus which is free of a discharge valve and a check valve, is low in cost, and is capable of reducing vibration and noise due to a waterfall after the end of water pumping operation. The water-lifting pump apparatus has a suction tank (10), a discharge tank (20), a pump (30) for pumping water in the suction tank (10) into the discharge tank (20), and a discharge piping (50) connected to a discharge side of the pump, an actuator (60) for actuating the pump (50), a reverse flow preventing mechanism (80) for preventing a reverse flow of water pumped into the discharge tank (20) toward the discharge piping (50), and a back flow rate control (90) for controlling the flow rate of a waterfall falling from the discharge piping (50) into the suction tank (10) when pumping operation is finished.
