    摘要: A field effect transistor (FET) with high withstand voltage and high performance is realized by designing a buffer layer structure appropriately to reduce a leakage current to 1×10−9 A or less when a low voltage is applied. An epitaxial wafer for a field effect transistor comprising a buffer layer 2, an active layer, and a contact layer on a semi-insulating substrate 1 from the bottom, and the buffer layer 2 includes a plurality of layers, and a p-type buffer layer composed of p-type AlxGa1−xAs (0.3≦x ≦1) is provided as a bottom layer (undermost layer) 2a. A Nd product of a film thickness of the p-type buffer layer and a p-type carrier concentration of the p-type buffer layer is within a range from 1×1010 to 1×1012/cm2.

    摘要: An ultrasonic probe includes ultrasonic piezoelectric elements that are arranged in a first direction at predetermined intervals and transmit and receive ultrasonic waves in a second direction substantially orthogonal to the first direction. The respective ultrasonic piezoelectric elements have plural grooves, which are parallel to the first direction and do not pierce through an end face, on at least one end face of two end faces substantially orthogonal to the second direction of the respective ultrasonic piezoelectric elements. The ultrasonic waves are weighted in a third direction orthogonal to the first direction and the second direction according to shapes and arrangement of the respective plural grooves and transmitted and received. In addition, a conductive member is joined to the end face having the grooves of the respective ultrasonic piezoelectric elements along the third direction.

    摘要: A sound reproduction system has pairs of sound emitters that subtend different angles Θ, the span angle, at the listener position. The pairs of sound emitters are arranged to be excited by different frequency bands of the signal output from an inverse filter means (Hh, Hl). The operational span-frequency range of the pairs of sound emitters is determined by an equation (I) where the transducer span Θ is the angle subtended at the listener by a pair of transducers, where O

    摘要: The object of this invention is to provide a novel pharmaceutical composition for getting rid of pains and anxiety in patients. This invention relates to a pharmaceutical composition containing lactoferrin as an active ingredient. The composition of this invention is useful for treatment of at least one disease or condition selected from the group consisting of pains, including the phase 1 pain and the phase 2 pain, anxiety and stress. The composition is particularly beneficial to alleviating or getting rid of the pain and anxiety which significantly lower quality of life of patients with end-stage cancer. The composition of this invention is also useful for treatment of pains, including the phase 1 pain and the phase 2 pain, and inflammation which accompany arthritis or diseases in the junctions of bones (e.g. rheumatoid arthritis, osteoarthritis, frozen shoulder, sports injuries such as tennis elbow and baseball shoulder, and low back pain).

    摘要: A television signal receiving apparatus which can read program information relevant to a television program from an optical disk medium, interlocked with the television program and can reproduce and display the read program information. Program information (broadcasting information including program names, broadcasting channel names and broadcasting dates and times and appendant information relevant to the contents of the programs) relevant to the television programs to be displayed by the television receiver/display is recorded in the optical disk medium. When a user instructs a display of the program information by the selection and decision input unit, the television control unit transmits the display request and time information from the clock apparatus to the control unit of the optical disk unit. The control unit makes the appendant information to be reproduced from the optical disk medium, by using the broadcasting channel name and the time information as retrieval information. The appendant information is sent to the television receiver/display through the interface and is displayed in a picture and sound.

    摘要: Digitally-compressed audio and image data of a plurality of programs (logical channels) are distributed and superimposed for every horizontal synchronizing signal period together with identification information of each of the programs in place of a luminance signal of an analog video signal of each of physical channels. Each of the physical channels is superimposed in its frequency and distributed from a signal transmission facility of a broadcasting station. At the receiving side, a desired physical analog channel is tuned and the compressed digital audio and image data superimposed on the tuned video signal are selected and taken as desired logical channel data in reference to program identification information, and the compressed digital audio and image data are decoded to obtain their original audio and moving images. With such an arrangement as above, in an existing CATV system, a mere insertion of an encoder unit into a transmission side and a decoder unit into a receiving side, without improving a characteristic of an analog video signal distribution system such as a cable or the like, respectively, enables a greater number of programs to be supplied correspondingly by the amount of digital compression.
