Title: Wet spinning method
Inventor: YAMANE CHIHIRO
IPC: D01D5/06
Filed: 1994-04-06
Abstract: PURPOSE:To enable tension applied to yarn in a spinning process to arbitrarily control, reduce spinning tension, prevent yarn from being taken in solidifying liquid stream and subjecting a high polymer solution to wet spinning at a high speed. CONSTITUTION:In a flow bath spinning method having a flow pipe just after spinning and reducing resistance to liquid by moving a solidified liquid in the same direction to advancing direction of yarn, this wet type spinning method is carried out by carrying yarn on a net formed at the top of the flow pipe, removing the solidified liquid on the net while more rapidly traveling a speed of the net than that of the solidified liquid flow and detaching the yarn on the net at a speed faster than that of the net.

Title: Multilayer capacitor
Inventor: KAZAMA SATOSHI
IPC: H05K3/34
Filed: 1996-03-25
Abstract: PROBLEM TO BE SOLVED: To provide a mutilayer capacitor which can hardly cause a positional offset at the time of soldering for mounting the capacitor on a circuit board. SOLUTION: The multilayer capacitor 30 comprises an element body 33 of a rectangular parallelopiped shape made up of dielectrid layers and internal electrodes alternately stacked and also comprises a pair of external electrodes 34 provided to both ends of the element body 33 as connected alternately in parallel to the internal electrodes. The external electrodes 34 are curved as projected in a direction vertical to upper and lower faces of the element body 33. Accordingly, at the time of mounting the capacitor on a circuit board, the external electrodes 34 formed on the face opposed to the circuit board are bent as projected in a direction vertical to the face. The external electrode 34 formed on the surface opposite to the substrate, has a curved shape vertically extending from the surface. Therefore, when the multilayer capacitor 30 is mounted so that the external electrodes 34 are positioned on solder paste attached to lands of the circuit board and then heated, even generation of surface tension on the melted solder causes the solder to escape into both sides of the external electrodes 34 along its shape, whereby the capacitor 30 can be fixedly mounted at a desired mounting location without causing any displacement.

Title: Noncontact method and instrument for measuring thickness of light transmissive thin film
Inventor: IWASAKI KUNIHIKO
IPC: G01B11/06
Filed: 1992-02-18
Abstract: PURPOSE:To measure the thickness of a thin film in a noncontact state by utilizing that a shift in phase angle occurs in pressure waves generated when a sample is irradiated with a light beam in corresponding to the thickness of a thin film. CONSTITUTION:When a sample TP is irradiated with a light beam LB after the beam LB is modulated in intensity by means of a modulator 12, part of the beam LB is absorbed into the sample TP and converted into heat energy. Since the heat energy is transmitted to the outside of the sample TP as pressure waves, the pressure waves are detected by means of an acoustic detector incorporated in a sample cell 22. The detected acoustic signal SS is sent to a phase difference measuring instrument 23 and compared with a modulated signal MS from the modulator 12. Based on the shift in phase angle of the detected acoustic signal SS, the thickness of a thin film formed on the surface of the sample TP is calculated. The thickness of the thin film changes proportionally to the shift in phase angle. Therefore, when the film thickness is calculated based on the shift in phase angle, the film thickness can be found with high accuracy in a noncontact state.

Title: Sheathing method for free length part of anchor
Inventor: NAKANO SUMIO
IPC: E02D5/80
Filed: 1985-04-03
Abstract: PURPOSE:To prevent a grout material and water from entering a sheath material, by a method wherein the free length part of an anchor is covered with a sheath material, and an expanding cut-off material is poured in the sheath material to be expanded in the sheath material. CONSTITUTION:Stretching materials 11, e.g., PC steel wires, are arranged in parallel in the shape of a cylinder, and a sheath material 2, e.g., polyvinyl pipes, is situated to the outer periphery of a free length part B. Ends across the free length part are secured to the stretching materials 11 by means of a span seal S and a tape T to form an anchor. By pouring an expanding cut-off material M through a pouring hole 21 of the sheath material 2, the expanding cut-off material M is expanded in the sheath material 2 to produce a solid, e.g., urethane foam to fill a space in the sheath material 2 therewith. This, when an anchor is inserted into a hole to fill with grout, prevents grout, water, and the like from entering the sheath 2.

Title: Slit lamina cooling device for hot rolled steel sheet
Inventor: MAKIHARA KATSUMI
IPC: C21D9/52
Filed: 1985-04-03
Abstract: PURPOSE:To make uniform cooling of steel sheet feasible by setting a length of slit lamina nozzle shorter at both ends in a direction of breadth than in a middle part. CONSTITUTION:A header 1 of a slit lamina cooling device is connected to a pump 4 through a flow rate control valve 5. The quantity of water membrane flow rate from a slit nozzle 2' is determined by the difference DELTAH in height of water level at an end of nozzle and that of header 1. By changing the length of the slit nozzle 2', the height DELTAH1 of head in the middle part is made larger than the height DELTAH2 of head at both ends in a direction of breadth. As a result, the cooling flow speed is made larger in the middle part in proportion to the square root of head height DELTAH, and the cooling capacity is increased. By this method, the uniform cooling is performed for hot rolled steel sheet as a whole.

Filed: 1998-03-03
Abstract: PROBLEM TO BE SOLVED: To reduce the influence of the irregular operation of a shutter and to restrain the dispersion of the line width of a resist pattern formed on a wafer by controlling output from a light source in accordance with the state of the progress of the opening/closing operation of the shutter. SOLUTION: Luminous flux from a mercury lamp 2 is made incident on a beam splitter 4, the luminous flux reflected by the beam splitter 4 is condensed on the other focal position of an elliptical mirror 3, and the shutter 9 is arranged at the focal position. The rotating position of a shutter blade is measured by a rotary encoder 8. The dispersion of the operation of the shutter is known about 3 ms after issuing an opening/closing command for the shutter. Based on the shutter position obtained after 3 ms, supply power to the mercury lamp 2 is changed for only 9 ms from 3 ms to 12 ms after starting closing operation. Even when the supply power is changed, the output of the mercury lamp 2 does not follow the change immediately, so that such a change ratio that integrated exposure may be always its standard value is experimentally obtained.
