Title: Manufacture of no defect heat rolled coil
Inventor: ARAKI SHOICHI
IPC: B21B15/00
Filed: 1992-10-21
Abstract: PURPOSE:To provide a means for removing a surface flaw efficiently and going a flaw removing process on line in a rolling line for a steel material. CONSTITUTION:An abrasive material is sprayed by a high pressure fluid jet current, that is, an abrasive water jet is applied to cutting the end of a hot roughing down material before a finish rolling process. The width 300mm or less of the end of the hot roughing down material is removed by 10-500mum by grinding under the conditions that the high pressure water pressure is 200-8000kgf/cm<2>, and the weight proportion of the supply amount of an abrasive material to the supply quantity of water is 0.05-2.2. Thus, the need of a rolling process after roughing-down and trimming for a defect part after acid cleaning can be eliminated so as to improve article forming yield rate. Furthermore, a line for removing a flaw such as a slitter line or a recoil line can be omitted so as to increase the efficiency of a line process.

Title: Pos terminal
Inventor: DEGUCHI MINORU
IPC: G07G1/12
Filed: 1987-11-10
Abstract: PURPOSE: To simplify registration work by presetting information for distinguishing whether delivery article or take-out article and adding that preset distinguishment information to transaction data usually, but performing the designating operation for the change only when it is desired to change that distinguishment information. CONSTITUTION: Sometimes, there is a customer taking out merchandise at a counter for mainly selling gifts and in such a case, a domestic use/gift key 22f is previously operated before the merchandise is registered. When setting the transaction data into an item buffer m2 , the contents of delivery section are inverted and a code '0' showing take-out is set to the delivery section. Thus, since the take-out code is set by operating the domestic use/gift key 22f even after a delivery code is temporarily set to the delivery section, any merchandise is registered and its switching is easily performed as well.

Title: Spinning device for optical fiber
Inventor: SHIRAKO YUKINARI
IPC: B65H57/14
Filed: 1991-10-04
Abstract: PURPOSE:To eliminate twisting of optical fiber by forming the cross section of the guide groove of a turn pulley in a spinning device of optical fiber into a V-shape. CONSTITUTION:The lower end part of the base material 1A of optical fiber is melted in a heating furnace 2. Optical fiber 1 is pulled out to the vertical low part from a molten part M and cooled by a cooler 3 and thereafter coated in a coating part 4. Cross-linking reaction of coating resin is completed in a cross-linking part 5. Then, optical fiber is wound on a turn pulley 6 and the traveling direction is converted in the lateral direction. Optical fiber is wound on a winder 8 from a take-off device 7. Herein, the width of the upper opening part of the V-shaped groove 61 of the turn pulley 6 is larger than the outside diameter of optical fiber 1. The apex angle of V-shape is regulated to about 70-90 degrees. Optical fiber 1 is brought into contact with the inclines of both sides of V-shape in two points P, Q in the inside of the V-shaped groove 61. Rotation around the axial line of itself is inhibited by friction between optical fiber and the inclines and thereby optical fiber is not twisted. In a tape core-wire made of this optical fiber, inconvenience such as twisting, rounding and inversion is eliminated.

Title: Fault point locating device
Inventor: TAKASHIMA TOSHIHIRO
IPC: G01R31/08
Filed: 1996-10-25
Abstract: PROBLEM TO BE SOLVED: To locate a fault point reliably by detecting the occurrence of the fault of a transmission line based on the detection value of a current, stopping the updating of a current waveform in a certain amount of time, and locating a fault point from the current waveform of a plurality of points. SOLUTION: When a grounding fault occurs at a transmission line between two iron towers, the polarity of a surge current is inverted between the detection values of the current sensor of both iron towers and the phases of the grounding current deviate by 180 deg. each other. A computer 10 judges that a fault occurred when the current value exceeds a predetermined threshold and the phases of the grounding current of adjacent local stations deviate by 180 deg. and enable local stations LS1-LS4 to stop updating the current waveform in a predetermined amount of time. After that, the computer 10 reads the current waveforms of the local stations LS1-LS4 from a ring buffer 11, compare and discuss them, and totally locate a fault point, thus achieving a reliable measurement with less influence, for example, by noise.

Filed: 1989-10-31
Abstract: PURPOSE:To improve conductive paste in affinity for the wall of through-hole so as to improve the through-hole in reliability of conduction by a method wherein the wall face of the through-hole is treated with a silane coupling agent before the conductive paste is filled into the through-hole. CONSTITUTION:A double side copper plated laminated board is prepared, where an inner sheet base material formed of glass non-woven fabric and surface sheet base material formed of glass woven fabric are impregnated with epoxy resin to constitute an insulating layer. A through-hole is drilled in the laminated board at a prescribed position, and the copper foil plated on both the sides of the laminated board are subjected to an etching process to form the prescribed printed wirings. The wiring board is dipped into an amino silane coupling agent to treat the wall face of the through-hole, and silver paste is filled into the through-hole through a printing method and cured by drying.

Title: Production of piezoelectric oscillator
Inventor: YUHARA KENSUKE
IPC: H03H3/02
Filed: 1989-10-31
Abstract: PURPOSE:To prevent the occurrence of cracks at the time of high power driving by completely uniformizing the electric field direction to the thickness direction of a plate-shaped oscillator throughout the surface of the oscillator at the time of polarizing a piezoelectric oscillator by electrodes on both faces of the plate- shaped oscillator. CONSTITUTION:After an electrode 10 is extended by about 1mm in the thickness direction to form an electrode 14, a silver paste containing glass frit is baked to form electrodes. A conductive paste silver electrode 16 made of a conductive paste which can be washed away with a solvent is applied to insulating parts of electrodes 11 and 12 formed by baking. Consequently, electrodes 11 and 12 are formed into one electrode by the conductive paste silver electrode 16, and polarization is performed in this state to uniformize the electric field direction to the thickness direction of a disk-shaped oscillator. Thus, a conventional problem of distortion between electrodes due to ununiform polarization is resolved, and the occurrence of cracks is prevented even in the case of a high power input.

Title: Steel pipe pile construction method and steel pipe pile pressing-in device
Inventor: AKIBA MASAKI
IPC: E02D7/20
Filed: 1995-11-01
Abstract: PROBLEM TO BE SOLVED: To perform the steel pipe pile driving for a light building at no vibration and noise by pressing steel pipe piles into a support ground by a downward pressing force while a frictional force with the ground is being decreased by the application of a rotational force to the steel pipe piles. SOLUTION: A chuck 7 of a pressing part 4 lowers a first pile 10 while rotating it horizontally so as to provide a rotating force and downward pressing force to the first pile 10 for pressing-in. Also the chuck 7 alters the installation position properly according to the pressing in depth of the first pile 10. By this, no vibration and noise by hammering will be generated. Because a steel pipe pile can be buried unless a hole is excavated beforehand, any large driving machine is not needed, any residual soil is not discharged, and the work becomes very small. Thus a steel pipe pile driving can be perfomed at no vibration and noise, and also a subsidence of a light building due to compactness can be prevented by supporting piles.
