Abstract: PURPOSE:To prevent the contamination of optical operating parts caused by a flux and the misalignment of an optical fiber and to improve the workability by fitting a leg part of a preforming body into a second recessed part and melting it, pouring a molten brazing filler metal into a first recessed part and fixing the optical fiber to a fixing base. CONSTITUTION:A fixing base 5 is plated in advance by a brazing filler metal, and brought to die bonding onto a hybrid IC board 6. As for the tip part of an optical fiber 1, metallic plating is performed in advance so as to be suitable for brazing, and its tip part is placed in a recessed part 5a. In the fixing base 5, another recessed part 5b is formed in advance, and in this recessed part 5b, a leg part of a preforming body 7 consisting of a brazing filler metal containing no flux is fitted in a shape of stepping over the optical fiber 1. In this state, the preforming body 7 and the fixing base 5 are heated, and the molten preforming body 7 is allowed to fill a gap between the surface of the recessed part 5a and the optical fiber 1. Thereafter, by discontinuing the heating, and cooling and solidifying the preforming body 7, the optical fiber 1 is fixed to the fixing base 5.

IPC: C07H15/04
Filed: 1990-05-02
Abstract: PURPOSE:To obtain the subject alkylglycoside of remarkably high quality in relation to hue and odor by giving a specified treatment to a crude alkylglycoside and efficiently separating and removing unreacted higher alcohols and impurities without requirement of heating at a high temperature. CONSTITUTION:Water and a lower alcohol (preferably ethanol or methanol) are initially added to a crude alkylglycoside containing <=15wt.% unreacted higher alcohols and impurities to obtain a homogeneous solution.

Title: Fluorescence analyzer
Inventor: AKI TOSHINOBU
IPC: G01J3/443
Filed: 1994-05-30
Abstract: PURPOSE:To reduce an error at fluorescence detecting time, and prevent the degradation of S/N by reducing stray light received by a fluorescence detector by being reflected directly or inside of a fluorescent chamber among excitation light, by a shielding body. CONSTITUTION:In a fluorescence detecting process, first of all, sample gas is sealed in a fluorescent chamber 4 from a sample introducing part 5. Among white light nondirectionally emitted by a Xe lamp 1, only light having a wave length in an extremely narrow band of a half value width of about 6nm with 214nm particularly as its center is selected by a band-pass filter for exciting light, and is applied to the fluorescent chamber 4. SO2 in the fluorescent chamber 4 is excited by this light, and emits fluorescence in a wave length area of 230 to 400nm. Among this fluorescence, only a wave length of 300 to 400nm is transmitted by a band-pass filter for fluorescence, and is detected by a photomultiplier 8. Here, since a light shielding body 11 is arranged, among exciting light, stray light received by the photomultiplier 8 by being reflected directly or inside of the fluorescent chamber 4 is attenuated. Thereby, an error at fluorescence detecting time can be reduced.

Title: Driving system for stepping motor
Inventor: ARAKI SHIGEYUKI
IPC: H02P8/28
Filed: 1979-09-11
Abstract: PURPOSE:To rotate the motor in the forward direction without fail at the next driving time in the case the stepping motor is driven from the stationary condition; by exciting the stationary phase, which is excited by a retaining current, by the driving current; and then driving the next phase by the driving current. CONSTITUTION:In the ribbon feed control, input pulses A are directly supplied to a set-reset flipflop circuit 17, and a ribbon feed driving signal L is instantly generated. Therefore, the stationary phase of a ribbon feed motor, which has been excited by a retaining current so far, is instantly excited by the driving current; and the motor returns to the normal position from the stationary position in the reverse direction caused by the reverse rotating torque of the driven load. After the delayed time M caused by a delay circuit 25, an AND gate 27 is opened, and a signal N actuates a clock generating circuit 18. Clocks O from the clock generating circuit 18 are counted by a counter 19 at every 4 counts. The motor rotates until the next stationary position depending on said 4 pulses.

Title: Field effect transistor
Inventor: MORI MUTSUHIRO
IPC: H01L29/772
Filed: 1984-06-08
Abstract: PURPOSE:To obtain a field effect transistor, whose switching speed is very high, by forming a so-called heterojunction, wherein the width of the forbidden band of an n-layer is broader than the width of the forbidden band of a p-layer, in a p-n junction. CONSTITUTION:n-layers 200, 210 and 220 of an electrostatic induction transistor 10 are formed by Si. A p<+> layer 300 is formed by a mixed crystal of SixGe1-x (0<=x<1). The n<-> Si layer 210 and the p<+> SixGe1-x layer 300 form a heterojunction. In this constitution, electrons 40 are injected to the p<+> layer 300. The injection of holes 50 is blocked by an energy barrier, which is caused by the difference in widths of the forbidden bands of the Si and the SixGe1-x. Therefore, stored carriers in the n<-> layer 210 becomes extremely less. Thus the switching speed of BSIT is improved to a large extent.
