    摘要: A light responsive semiconductor device includes a p-i-n structure incorporating a multiple quantum well structure buried within the intrinsic layer and an external resistance and voltage source serially connected across the device for adjusting a critical wavelength at which the light absorption characteristic of the device dramatically changes. By properly choosing the resistance and/or voltage, the photocurrent changes discontinuously at the critical wavelength and the photocurrent exhibits a hysteresis characteristic. A light responsive structure may include individual, serially aligned p-i-n devices or an integrated, unitary semiconductor body inculding a plurality of p-i-n devices.

    摘要: The foam sheet of the present invention is biodegradable, can be recycled, has good processability, is lightweight, exhibits excellent appearance, has practically satisfactory heat resistance and is more acceptable to the environment. There is provided a crosslinked biodegradable resin continuous foam sheet comprising biodegradable resin, and has an expansion rate of about 1.5 to about 50 and a gel fraction of about 3% or more. There is further provided a method for producing the foam sheet comprising the steps of: (1) preparing a sheet from a resin composition comprising a biodegradable resin, a thermal decomposable blowing agent, and a crosslinking promoter; (2) irradiating the resulting sheet with an ionizing radiation to crosslink the resin composition; and (3) subjecting the crosslinked sheet to heat treatment to continuously prepare a crosslinked foam sheet. Thus, the foam sheet of the present invention can be used in a wide range of practical applications such as, for example, interior materials for an automobile, thermal insulators such as a pipe covering, cushioning materials such as a tape core and the like.

    摘要: It is to provide a high-frequency component using a small coupling line, capable of easily adjusting an electrical characteristic. A first transmission line including three line sections constructs a ¼-wavelength strip line. A second transmission line including three line sections also constructs a ¼-wavelength strip line. The line section on one-end side in the first transmission line is faced to the line section on one-end side in the second transmission line, while a dielectric sheet is disposed between both of the line sections, thereby mutually coupling both transmission lines electro-magnetically. The line section on another-end side in the first transmission line is also faced to the line section on another-end side in the second transmission line. While the dielectric sheet is disposed between both of the line sections, thereby mutually coupling both transmission lines electro-magnetically.
