Title: Vane for centrifugal compressor
Inventor: TAKASE KENJIROU
IPC: F04D29/30
Filed: 1979-04-06
Abstract: PURPOSE: To raise overall efficiency by uniforming the outflow angle distribution at outlet with the outlet side of blades inclined oppositely to the running direction of a disc.  
     CONSTITUTION: A vane consists of a disc 1a and the blades 1b radially protruded on the front face of the disc 1a. The blades 1b are shaped straight and radial or bent oppositely to running direction. The outlet side of the blades 1b is inclined β (inclination angle) oppoistely to the running direction of the disc 1a. Thereby, the flow angle distribution at the outlet of the vane 1 is uniformed. Consequently the restoration factor of the internal static pressure of a diffuser 4 is made higher by about 0.58W0.60 than the conventional ones in which blades are inclined and  the coefficient of the pressure is increased by about 13% so that overall efficiency is  raised.

Title: Manufacture of ceramic substrate
Inventor: HORIKOSHI MUTSUMI
IPC: H05K3/46
Filed: 1988-02-24
Abstract: PURPOSE:To prevent a metallizing pattern from expansively deforming along the surface of a green sheet during lamination pressing in order to keep a predetermined dimension thereof, by a method wherein a pattern corresponding to the negative of a wiring metallizing pattern which is formed on the green sheet is printed by using ceramic paste, and the thickness of the ceramic paste posterior to printing is made substantially equal to the thickness of the metallizing paste. CONSTITUTION:A metallizing paste 2 is printed on a green sheet 1 to form a metallizing pattern. Next, a pattern corresponding to the negative of the metallizing pattern is printed by using a ceramic paste 3. At this time, the viscosity of the ceramic paste 3 is previously regulated by an organic solvent or the like so that the thickness of the metallizing paste 2 is substantially equal to that of the ceramic paste 3. In such a manner, an inner pattern is formed, and by using a film 4 in which a polyester film is coated with a parting compound, a lamination pressing is performed. At this time, since the ceramic paste serves as a dam, the expansive deformation of the metallizing paste can be limited by the ceramic paste. As a result, during lamination pressing the expansive deformation of the metallizing paste can be effectively reduced.

Title: High mobility semiconductor material
Inventor: YAO TAKAFUMI
IPC: H01L21/20
Filed: 1982-03-16
Abstract: PURPOSE:To obtain a mixed crystal semiconductor material of which mobility is high  by such an arrangement wherein a buffer layer is deposited on a substrate, and layers  of semiconductors, each differs in constitution from other, are alternately and regularly  laid over another by the unit of 1mol layer or 2mol layer on the buffer player. CONSTITUTION:On a substrate 7 made of semiconductor or insulation material, a buffer layer 8 of semiconductor or insulation material is caused to grow, and on the layer, a layer 9 of AX single molecule and a layer 10 of AqB1-qX (0<=q<1) single  molecule are alternately deposited by 1mol layer up to a desired thickness. Since carriers in the direction parallel with the substrate 7 detect regular lattice potential such  as A-X-A-X... in the layer 9, they can realize mobility of high speed without being affected by the influence of alloy dispersion. On the one hand, in the layer 10, alloy dispersion and space charge dispersion exist, except q=0. However, at the time of q=0,  the layer 10 becomes BX, and there exists no alloy dispersion nor space charge dispersion. In any case, the average mobility of the layer 9 and layer 10 in the direction parallel with the substrate 7 becomes larger. On the one hand, the mobility of carriers running in the direction perpendicular to the substrate also becomes larger, as the irregularity of potential is lessened.

Abstract: PURPOSE:To monitor the oscillation wavelength of a laser diode with a simple optical system by arranging a wavelength filter on an optical path, where the emission light of the laser diode is reflected with a beam splitter, and detecting the light transmitting through the wavelength filter. CONSTITUTION:A wavelength filter 14 is arranged on the optical path of the parallel light reflected with a beam splitter 3 from the beam splitter 3. The emission light of a laser diode 1 is shaped to the parallel light with a collimator lens 2, transmitted through the beam splitter 3 and guided to a reflection mirror 4. Then, a part of the light is reflected with the beam splitter 4, passes through the wavelength filter 14 and arrives at the light receiving surface of an optical detector 15. The longer the wavelength of the light is, the more the transmissivity of the wavelength filter 14 is increased. Accordingly, when the oscillation wavelength of the laser diode 1 is changed with a temperature change or degradation with the lapse of time, the received light quantity of the optical detector 15 is changed. Thus, the oscillation wavelength of the laser diode 1 can be monitored.
