摘要:
A laminated structure composed of a substrate web and a thermoplastic resin web extrusion-coated thereon, which is substantially free from an offensive odor, is produced by extrusion-coating the thermoplastic resin web in the molten state through a T-die on the substrate while applying an oxidizing gas to one surface of the as-extruded molten web of the thermoplastic resin and an inert gas to its other surface in a specified space.

In a switch unit, abutting portions are provided on a movable contact in such a manner as to be brought into contact with stepped portion of a switching control element, respectively, so that when the switching control element is operated to rock, the abutting portion elastically ride on the stepped portions, so as to impart a click to the rocking operation of the switching control element, whereby the click can be imparted to the rocking operation of the switching control element without requiring a clicking piece and a spring which are required in a conventional switch unit.

A master device and a slave device are each constituted of a transmitting section; a receiving section; and a control section including a three-dimensional position calculation section for calculating a three-dimensional position of the transmitting section of the counterpart master device or that of the counterpart slave device and an element drive section for driving an MEMS element. First, the master device outputs transmission light having comparatively narrow directivity, and the transmission light is two-dimensionally scanned. Next, the receiving section of the slave device receives that transmission light, calculates the transmission direction of the master device from the position of a spot of transmitted light on a light-detecting element array, and transmits the transmission light in that direction. At this point in time, scanning of the transmission light from the master device is stopped, and subsequently communication is initiated.

An optical disk apparatus includes a carriage, a plurality of objective lens support portions, and a plurality of magnetic field generating means. The carriage is placed to oppose an optical disk and held to be reciprocally movable between an outer peripheral portion of the optical disk and its central portion. Each of the objective lens support portions has an objective lens elastically supported by an elastic member. The magnetic field generating means move each of the objective lenses in a direction perpendicular to the surface of the optical disk and a radial direction of the optical disk. Some of the magnetic field generating means which are used, in pairs, for the objective lens support portions are shared by the plurality of objective lens support portions.

An excitation wavelength sweeping type Raman spectroscopic apparatus including a wavelength variable laser source, a laser beam converging unit for irradiating a laser beam from the laser source onto a specimen, a bandpass filter for selecting a beam of a predetermined wavelength out of Raman scattered light beams emitted from the specimen, and a photodetecting unit for detecting the beam selected by the bandpass filter. In the apparatus, a Raman spectrum of the specimen is measured by sweeping the wavelength of the laser beam.

Melt bags of the invention are molten uniformly at temperatures lower than melting operation temperatures in the product manufacturing and do not remain unmolten in the final products. The melt bags have high storage stability and excellent mechanical properties. Resin compositions of the invention are suited to give such melt bags.A resin composition of the invention includes a propylene/C2-20 α-olefin (except propylene) copolymer (A) having (1) a melting point (Tm) of not more than 90° C. as measured by differential scanning calorimetry (DSC) or not showing a melting point peak in DSC, and an ethylene/C3-20 α-olefin copolymer (B) having (1) a melting point (Tm) of not more than 90° C. as measured by differential scanning calorimetry (DSC) or not showing a melting point peak in DSC, the weight ratio of these copolymers (A)/(B) being in the range of 99/1 to 1/99.

A switch device in a steering wheel includes a front switch assembly and a back switch. The front switch assembly is provided on a front side of the steering wheel that faces the driver, and rotates integrally with the steering wheel. The back switch is provided on a back side of the steering wheel. The front switch assembly includes at least one front switch. The front switch assembly also includes a circuit board. A front switch light source is provided on the circuit board. The front switch light source illuminates a switch marking provided on the front switch. On the circuit board is also provided a back switch light source for illuminating a switch marking provided on the back switch. Accordingly, a manipulation switch on the steering wheel is reliably illuminated regardless of the rotation angle of the steering wheel.
