Abstract: NEW MATERIAL:(3,3,3-Trifluoropropyl)biphenyl of formulasI-III. USE:Useful as an insulating material and an intermediate for organic syntheses. PROCESS:The titled compound can be prepared by reacting biphenyl with 3,3,3- trifluoropropene in the presence of an acid catalyst. The o-, m- and p-isomers can be obtained selectively according to the reaction conditions. For obtaining  the o-isomer of formulaI, it is preferable to use BE3 as the acid catalyst in an amount of >=0.5 equivalent per 1 equivalent of biphenyl when the amount of 3,3,3-trifluoropropene is equimolar to biphenyl, and to set the reaction temperature to 0-150 deg.C. In the case of obtaining the m-isomer of formula II, it is preferable to use HF-BF3 as the catalyst wherein the amounts of HF and BF3 are >=0.5 and >=0.02 equivalent per 1 equivalent of biphenyl, respectively. The reaction temperature is preferably 30-100 deg.C. For the preparation of p-isomer of formula III, the catalyst and its amount are same as those of the preparation of m-isomer, and the reaction temperature is preferably -20-+30 deg.C.

Title: Moire scale
Inventor: INABA TAKAO
IPC: G01D5/38
Filed: 1987-05-25
Abstract: PURPOSE:To improves S/N and a resolution by using a laser for a light source and by setting a grid space of a scale to be a prescribed pitch or less. CONSTITUTION:A semiconductor laser is used for a light source 20, and grid pitches of an index scale 22 and a main scale 24 are set to be 10mum or less, for instance. By this constitution, a laser beam emitted from the light source 20 is turned into parallel beams by a collimate lens 16 and then reaches the scale 22. Although moire fringes are formed by the respective grids by the scales 22 and 24, diffraction angles of primary and secondary diffracted beams are large since the grid pitches are small, and therefore these beams do not appear on the photodetector 18 side. Accordingly, only the moire fringes due to a zero-order diffracted beam is detected by the photodetector 18, and length and detection of displacement are measured by a signal processing means by using an output signal of the element 18. By making the grid pitches of the scales small so that only the zero-order diffracted beam be transmitted, in this way, a resolution can be improved, and thus an excellent contrast can be obtained.

Filed: 1982-07-22
Abstract: PURPOSE:To form a semiconductor laser device, which is also excellent in heat radiating characteristics, with superior reproducibility by forming a P-N junction to a mesa section and forming a constriction with width smaller than the width of the mesa. CONSTITUTION:The mesa section with an active region is formed through mesa etching up to a GaAs substrate 1 by an etching process. When HF is used as an etching liquid and the surface is etched slightly for several sec while the liquid is agitated, only a P type Al0.6Ga0.4As layer 12 is etched, and the constriction 13, width thereof is made narrower than the width of the mesa, is formed. Layers 6, 7, 14 are formed in succession so as to surround the mesa section by a second crystal growth process. Since there is the constriction 13 in the mesa section, the layer 6 does not grow to a section upper than the constriction 13, and the growth of the layer 6 can be stopped positively in a constriction 13 section. The layer 7 stops in the upper section of the constriction 13, and a crystal growth is not caused up to a section upper than the constriction.

Title: Surface acoustic wave device
Inventor: KIMURA NORITOSHI
IPC: H03H9/145
Filed: 1996-05-23
Abstract: PROBLEM TO BE SOLVED: To obtain a surface acoustic wave device with high reliability without electrode corrosion caused during the manufacturing process by forming an aluminum alloy film to which tungsten is added onto a piezoelectric substrate and using it as a reflector. SOLUTION: Excellent breakdown voltage is confirmed by using an Al-W alloy thin film for a reflector of the high frequency surface acoustic wave device. The tungsten W solid-solved in the aluminum Al in the Al alloy thin film to which W is added gives direstortion to Al lattice to suppress the Al from being diffused, resulting that production of voids or blocks is suppressed. Concretely over all contents in a plotting whose X axis indicates a content of a added metal and whose Y axis depicts element service life (TF), the service life of the Al-W electrode film is longer than the service life of the Al-Ti electrode film. That, is excellent breakdown voltage is obtained. Moreover, the service life of the Al-Ti electrode film with respect to the content of 0.5at% or over is not increased but saturated.  The service life of the Al-W electrode film is about 5 times the service life of the Al-Ti electrode film at this content of 0.5at%.

Abstract: PURPOSE:To simplify the constitution of a mis-operation prevention circuit and to lower the cost of a digital radio system, by constituting a circuit so that the output of the gate circuit of a line in which forced switching is performed first is distributed to the gate circuit of another line, and the output of the manual switch in another line operated by a mis- operation can be negated afterwards. CONSTITUTION:The gates 2A and 2B of a transmission terminal switching board A and a transmission terminal board 2B consist of AND gates 21A and 21B, respectively, and to the input terminal on one side of each of the AND gates 21A and 21B, the inverted output H of each output L of bipolar switches 1A and 1B is inputted, and to the input terminal on the other side, the inverted output L of the gate output H of another switching board is inputted, then, an AND processing is performed. And each processed output of the AND gates 21A and 21B is outputted to the outside via each of distributors 3A and 3B as the switching instruction CA of the transmission terminal switching board A of a current in use line switched forcibly first and as the switching instruction CB of the transmission terminal switching board B of the current in use line mis-operated successively. Therefore, the output of the AND gate 21B of the gate 2B goes to an L even when the switch 1B of the transmission terminal switching board B is turned ON accidentally and the H of the inverted output of the switch 1B is inputted to the input terminal on the other side of the AND gate 21B, then, no switching instruction CB is outputted.
