摘要:
A panel for an airbag of an automobile is formed by integrally molding a cover body, which is made of a synthetic resin, with a main body, made of another synthetic resin. The panel includes a joint portion, joined with the cover body, and provided around an opening portion formed in the main body. The joint portion constitutes an overlapping portion in which an outer peripheral edge of the cover body is overlapped as being arranged on the inner side of an opening edge of the main body.

Incident light 19 emitted from a laser light source 18 is reflected on an upper surface of a cantilever 13, so that reflected light 19a enters light detection means 20. Since the incident light 19 and the reflected light 19a are in a plane not including a long axis of the cantilever 13, movements of the reflected light 19a due to change in a deflection amount θ of the cantilever 13 and due to change in a fine vertical movement amount z thereof are different in direction on the light detection means 20. This enables the change in the deflection amount θ of the cantilever 13 and the change in the fine vertical movement amount z thereof to be separated from output of the light detection means 20.

An electron beam irradiation device of the present invention includes: a projector 8 for generating a two-dimensional light pattern 13; a microchannel plate 11 for (i) generating an electron beam array based on the light pattern 13 having entered, (ii) amplifying the electron beam array, and (iii) emitting the electron beam array as an amplified electron beam array 14; and an electron beam lens section 12 for converging the amplified electron beam array 14. This electron beam irradiation device is capable of manufacturing a semiconductor device whose performance is improved through a finer processing by means of irradiation using an electron beam. Further, the electron beam irradiation device allows cost reduction, because the device allows collective irradiation using a two dimensional pattern.

A combined atomic force and near field microscope assembly for atomic level inspection of a target object. The assembly includes a scanning probe with a sharp tip and a photosensitive region on its lower surface. A sample is disposed on a glass substrate and exposed to an evanescent wave generated on the glass substrate by total internal reflection. An optical probe comprising a microfabricated cantilever having an apex in close proximity to a photosensitive region is disposed in close proximity to a sample. The photosensitive region collects light generated by FTR at the apex of the optical probe due to local disruptions of the evanescent field caused by the probe tip. A cantilever displacement mechanism is included so as to allow for operation in a second mode as a conventional atomic force microscope.

A cantilever stylus suited for use in an atomic force microscope is made in the following processes: forming a first film on a substrate; forming a second film of metallic material on an external surface of the first film; forming a photoresist film on an external surface of the second film by making use of a photolithography technique; performing etching with respect to the second film with only a portion thereof covered with the photoresist film left on the first film; and further performing etching with respect to the first film with the second film being used as a resist film so that the first film may be configured into a cantilever stylus.

A surge absorbing element has a first electrode, a second electrode, and a ceramic layer. The second electrode is opposed to the first electrode. The ceramic layer has a polycrystal structure including a plurality of crystal grains showing voltage nonlinearity, and is at least partially brought into contact with the first electrode and the second electrode. The ceramic layer has a void inside therein, and surface discharge is generated on surfaces, exposed to the void, of the crystal grains, whereby electric conduction is attained between the first and second electrodes.

Above the sample (9) having magnetic domains, a distribution of magnetic force in a measurement plane (91) is obtained as a magnetic force image with use of a MFM, an auxiliary magnetic force image is obtained by performing measurement in a measurement plane (92) away from the measurement plane (91) by a minute distance d, and a difference between them is divided by the minute distance d to obtain a magnetic force gradient image. The magnetic force image and the auxiliary magnetic force image are Fourier transformed and substituted into a three-dimensional field obtaining equation derived from a general solution of the Laplace equation, and the three-dimensional field indicating the magnetic force is obtained with high accuracy. A state of the magnetic domains at the surface (93) of the sample (9) can be obtained with high accuracy by obtaining the three-dimensional field. The three-dimensional field obtaining method using the three-dimensional field obtaining equation can be used for various fields of magnetic, electric, temperature and gravity potential and so on satisfying the Laplace equation. The obtaining of the three-dimensional field can be extended to obtaining of an n-dimensional field having high-dimension.

An object is to provide a gate valve capable of preventing operational deficiencies caused by particulate materials accumulating in a valve box, thus providing superior sealing properties and high durability, having a simple structure, and allowing inspection and maintenance to be performed easily. A gate valve installed in a transport line for transporting fluid containing particulate material at a coal gasification plant includes a valve box having an inlet portion and an outlet portion in which a channel constituting a part of the transport line is formed; a valve unit, provided between the inlet portion and the outlet portion, which extends in an opening-and-closing direction orthogonal to an axial direction of the channel, and which is movable in the opening-and-closing direction; a wedge plate provided between the valve unit and the inlet portion so as to extend in the opening-and-closing direction; and a guide plate provided between the valve unit and the outlet portion so as to extend in the opening-and-closing direction. Areas between the valve unit and the wedge plate and between and the valve unit and guide plate are sealed by means of surface contact.

Blow-molding molds 10 and 20 having parison shutters 31 and 32 for preventing an inflation of the parison 3 toward the outside of the molds 10 and 20 are used in a blow-molding method of the present invention. In other words, a closed space for preventing the parison 3 from inflating out of the molds 10 and 20 are formed by the parison shutters 31 and 32 and a predetermined air is secured in the parison 3 in a frame clamping step (B). In the subsequent mold clamping step (C), the pressure inside the parison 3 starts to be increased when the molds 10 and 20 press the parison 3, so that the parison 3 can be continuously in contact with the die design surface 11. Accordingly, since the parison 3 can be uniformly contracted by cooling, molding failure such as streaks and uneven pattern transfer can be avoided, thus obtaining a blow-molded product having good appearance.
