Title: Laser diode system for raman spectroscopy
Inventor: BURAIAN JIYON EDOWAADO SUMISU
IPC: G01J3/10
Filed: 1995-12-21
Abstract: PROBLEM TO BE SOLVED: To prevent a mode hopping and also suppress a side mode of a semiconductor laser. SOLUTION: A diffraction grating 18 receives laser beams from a semiconductor laser diode 12. The beams are diffracted by way of a first-order diffraction of the grating 18, passing through an aperture 26 selecting a required wavelength. As a result, a side mode of the laser diode is eliminated. A small part of the light is reflected at a glass window 26 and, returned and fed back to the laser diode, thereby to stabilize the laser diode. Accordingly, a mode hopping is prevented. A large part of the light of the required wavelength passed out to an output port 20 through the window 28. The output light has no side mode and is not subject to mode hopping, and therefor is fit for use as an exciting light at the spectroscopy including the Raman spectrometry.

Title: Guide rail device for suspended door
Inventor: MINAMI KANJI
IPC: E05D13/00
Filed: 1989-12-22
Abstract: PURPOSE:To reliably guide an overhang door by embedding a guide rail piece with which a magnet is retractably engaged, repeating protruding and retracting action by adsorption and repulsion operation between the guide rail piece and a long groove rail piece made of excitation of the lower end surface of the overhang door, and engaging a protrusion body with the interior in a position except two end parts. CONSTITUTION:A guide rail piece 1 where magnets 1C are engaged with a cylindrical outer cylinder 1A of a non-exciting substance and the top part of a protrusion body 1B retractably inserted in an engaging manner with the outer cylinder is embedded in a floor surface. The whole or a part of a long groove rail piece 2 made of non-excitation is engaged with the lower end surface of an overhang door. When the tip of the overhang door is moved to a position above the guide rail piece 1, a magnet 25 on the outside of the overhang door is repelled to the magnet 1C of the protrusion body and the protrusion body is retracted. When it is further moved to a deep groove part 22, the protrusion body holds a rise state, and when the rear end of the overhang door is moved to a position above the projection body, the protrusion body is retracted through repulsion of the two magnets to each other. As noted above, the protrusion body repeats protrusion and retraction through adsorption and repulsion action of the magnets 25 and 26 and the 1C at each overhang door, but when the protrusion body is in a position except the two end parts of the long groove rail piece, it is engaged with the interior to guide the overhang door. This constitution ensures reliable running of the overhang door and performs operation to prevent the occurrence of vibration.

IPC: B29C45/72
Filed: 1993-12-28
Abstract: PURPOSE:To make optical and mechanical characteristics sufficient by a method wherein an index of double refraction compensating the amount of change in the double refraction of a base occurring in each process is given to the base beforehand at the time of molding. CONSTITUTION:The double refraction of a base of a magneto-optical disk made of a synthetic resin changes in manufacturing processes. Most of this change is caused by processes of drying and fitting a hub which are conducted after molding of the base. In order to maintain the double refraction within the range of 0+ or -20nm, a phase delay in the circumferential direction in relation to the radial direction is made minus and a double refraction value Xnm at gammanm from the center of the base is made -5X10<-6>gamma+185<=X<=-5X10<-6>gamma+215 in double pass, a mold temperature Tm 110 to 125 deg.C, a cooling time of (t) seconds 0.13Tm-8.5<=t<=0.13Tm-4.5 and a compression pressure after injection 250 to 400kg/cm<2>, at the time of measurement of the double refraction of the base, in a base molding process wherein molten synthetic resin is injected into a cavity of a molding equipped with a cavity-side part, a movable-side part and a stamper provided between these parts. Thereby, the double refraction of the base can be made 0 finally.

Title: Abnormality-detecting device in spinning machine
Inventor: UEMATSU TATSUYA
IPC: D01H13/14
Filed: 1998-11-27
Abstract: PROBLEM TO BE SOLVED: To determine the yarn break and the abnormality of a power-supplying part to a motor in a spinning machine having each spindle independently driven by the motor installed for each of the spindles. SOLUTION: An electric current value at the input side of an inverter installed for each spindle is measured by a currant sensor to control the drive of a spindle motor. A judging circuit judges the presence or absence of yarn break and abnormality of a power-supplying part by comparing the measured current value with threshold Iα. The measured value of the current by the current sensor when the spindle motor is normally rotated in the state in which an empty bobbin is attached to the spindle is used as the threshold Iα.  The judging circuit judges that the state is the yarn break state when the measured current shows a constant value not less than the threshold Iα and the value continues for a prescribed time, and that the state is the abnormality of the power-supplying part when the value is a prescribed constant value less than the threshold Iα and continues for a prescribed time. The judging circuit distinguishes the abnormality of the power-supplying part into the partial abnormality of a phase wiring in the inverter, and the abnormality without the phase wiring in the inverter.
