Abstract: A console unit includes a substrate extending along a virtual plane. A support extends rearward from the front end. The substrate is received on the support. A console is connected to the front end of the support for relative rotation around a rotation axis intersecting the virtual plane. The console is allowed to occupy a larger space even if the substrate is reduced in size. The visibility of the console cannot be degraded irrespective of a reduced size of the substrate. Other components may be positioned adjacent the console unit. Replacement of the component is often required without detaching the console. The console is allowed to retreat from the path of movement of the component based on the rotational movement. Interference can reliably be prevented between the console unit and the other component during replacement of the other component.

Abstract: There is provided a low oil cream composition which does not require a large amount of any particular emulsifying agent but has good physical properties after the whipping as well as good flavor and melting property in the mouth, even a low oily ingredient content such as not greater than 40%, and also provides is an oil-and-fat feedstock for production of the cream composition. The oil-and-fat feedstock for production of the cream composition is obtained by formulating not less than 30% of SUS-type triglycerides and 5 to 60% of a lauric-type oil-and-fat ingredient. A low-oil cream composition can be produced by the feedstock alone or, by further adding a cream containing milk fat to the cream. Then, it is possible to provide a low-oil cream composition having flavor and body comparable with fresh cream and to provide a process for production thereof.

Abstract: In a method of manufacturing a polarization-maintaining optical fiber coupler by heating lengthwise portions of two polarization-maintaining optical fibers extending side by side, and elongating the heated portions to thereby form a fused-elongated section, elongation is terminated when the cyclic changes in a coupling ratio of two polarized waves according to an elongation length at a wavelength in use are both within first two cycles, so that the coupling ratio of one of the polarized waves is equal to or less than 10% and the coupling ratio of the other one of the polarized waves is equal to or greater than 90%. This method can provide a polarization-maintaining optical fiber coupler whose coupling ratio has a large dependency on polarization with a short elongation length.

Abstract: A method of producing an optical waveguide grating by exposure to light. An optical waveguide having a core composed of a material wherein the refractive index changes due to exposure to UV light is formed into an optical waveguide grating by applying a grating portion formation step wherein a grating portion is formed by irradiation with UV light at a predetermined spacing, and an overall exposure step after formation of the grating portion wherein the entire grating portion is irradiated with UV light. As a result, the effective refractive index of the grating portion is changed so as to allow the central wavelength to be adjusted without changing the rejection. Consequently, the grating properties can be precisely and easily controlled.

Abstract: An optical waveguide grating with radiative mode-coupling properties, with exceptional stability and reliability as an optical component, wherein the central wavelength of the rejection band has a low temperature dependence, due to the use of silica glass doped with germanium and boron for the core. The rejection bandwidth can be narrowed without increasing the grating length by forming the radiative mode-coupled optical waveguide grating in an optical waveguide wherein the mean relative refractive index difference of the core is greater than that of optical communication waveguides.

Abstract: Core comprises a main stem which is formed on a substrate, linearly extending in the beam propagating direction and short branches with a certain length which extend perpendicularly to the beam propagating direction toward both sides along the plane of the substrate and are arranged at regular intervals in the beam propagating direction. Thus, the branches are arranged in a ladder geometry when it is viewed from the top, forming a rectangular waveform arrangement. The core constitutes a grating structure in which the width of the core is made to vary periodically with the branches in the beam propagating direction.

The bottle comprises a plurality of fracturing walls, each formed in a longitudinal band shape extending substantially in a direction of a central axis of the bottle, and main walls each disposed between the fracturing walls. The fracturing walls are made of a first material and a second material, the first material being a synthetic resin that is the same as a synthetic resin forming the main walls and/or has good compatibility with the synthetic resin of the main walls, the second material being a synthetic resin that has poor compatibility with the synthetic resin of the main walls. The bonding strength between the fracturing walls and the main walls is controlled so as to make the bottle easily fractured. If necessary, an inner covering member can be assembled within the bottle.
