Filed: 1982-07-12
Abstract: PURPOSE:To attain the tracking even at a region forming signal information pits and to make the processing of information stable, by linking a part of signal information pits and a tracking guide. CONSTITUTION:Several tens of thousands of tracking guides 3 in spiral or in concentrical shape and signal information pits 4- representing ''picture signal'', ''track number'', ''sector number'', ''synchronizing signal'' and ''acoustic signal'' and the like are formed on an information recording section 2 in advance formed on an information storage medium 1 in ring shape, and the signal information pits 4- are formed on the tracking guides 3. The width l1 of the tracking guide 3 in this case is larger than the width l2 of the signal information pits 4(l1>l2) in this case. Further, the depth h1 of the tracking guides 3 is set to the size of lambda/8 to the wavelength lambda of the reading laser light so as to obtain the optimum tracking shift detection signal and the depth h2 of the signal information pits 4 is set to the size of lambda/4 so as to have the largest modulation. Since the signal information pits 4- and the tracking guides 3 are linked together, the stable tracking is attained even at the region forming the signal information pits 4-.

Title: Method of cooling rail
Inventor: TERAMOTO TOYOKAZU
IPC: C21D9/04
Filed: 1988-05-18
Abstract: PURPOSE:To forcibly cool the body and bottom part of a rail and to easily control the cooling power of the respective parts of the rails without overcooling the leg ends by injecting cooling water to the upper part and fillet part of the body part of the rail and injecting compressed air toward the leg instep part and the rear surface of the leg ends. CONSTITUTION:The rail 1 moving in an arrow direction is cooled by the cooling water supplied to the upper part of the body part 1a from laminar nozzles 3 of circular tubes. The cooling water flows downward to cool the fillet part 1b. The fillet part 1b is further cooled by the cooling water supplied from nozzles 5. The cooling water flows down to the leg part 1c but is moved in the moving direction of the rail 1 or the direction opposite thereto by the flow of the compressed air supplied from compressed air injection nozzles 10. The cooling water is, therefore, prevented from being desorbed from the leg ends 1d of the rail 1 over the entire length of the rail 1. The cooling water is temporarily stagnated on the surface of the fillet part 1b and is stirred by the flow of the compressed air, by which the cooling effect of the fillet part 1b is enhanced.

Title: Method for preventing spalling of rolling roll
Inventor: KOIZUMI AKIHIRO
IPC: B21B37/42
Filed: 1983-07-04
Abstract: PURPOSE:To prevent the generation of roll spalling by displacing the reference positions of intermediate rolls in the roll-axis directions within a range where the flatness of a rolling material is not deteriorated, in case of continuously rolling the material by the intermediate rolls located at the same reference positions. CONSTITUTION:In rolling a sheetlike rolling material 5 by a multiroll mill having intermediate rolls 3 movable in the roll-axis directions, the reference positions of the rolls 3 are previously set in accordance with the sheet thickness and sheet width of the material 5. In case of continuously rolling the material 5 while maintaining the reference postions of the rolls 3 at the same positions for a long time, the reference positions are slightly displaced by shifting the rolls 3 with the aids of shifting devices 4 within a range where the flatness of material 5 is not deteriorated. In this way, the generation of roll spalling is prevented, and the service life of roll is remarkably improved.

Title: Servo controller
Inventor: NAKAHARA KAZUHIRO
IPC: G05D3/12
Filed: 1988-05-20
Abstract: PURPOSE:To ensure the simple and safe analysis for the factor of abnormality by using a nonvolatile memory which updates and records cyclically the target position command, the target speed command and the position/speed feedback signals of a servo controller at a fixed time interval at and after the start of the servo control. CONSTITUTION:A memory 10a of a nonvolatile memory 10 records the servo control state 11 for the target position command 2 and the target speed command 3 as well as the position feedback signal 8 and the speed feedback signa l9. The memory 10a also can update and record cyclically the data within a range of its memory capacity and also the sate 11 at a fixed time interval for a period covering the start of the servo control through the end of this control or the break of a main power supply caused by occurrence of the abnormality. The final record position is grasped by a pointer 10b and backed up by a battery 10c. Thus the record contents and the position pointed by the pointer 10b can be held at the break of the main power supply. The changes of the state 11 up to the break of the main power supply can be recoded. Thus it is possible to avoid the danger involved in the regenerating job for occurrence of the abnormality and also to analyze safely and easily the factor such abnormality that has no retreatability.

Title: Base disc type grinding wheel
Inventor: FUJII TSUYOSHI
IPC: B24D5/06
Filed: 1998-05-01
Abstract: PROBLEM TO BE SOLVED: To improve the strength of a grinding wheel and to implement rotation grinding work at high circumferential speed by specifying the rate of the thickness of a binding layer to the elasticity of the binding layer to a prescribed range. SOLUTION: A grinding wheel layer is formed of being divided into a plurality of segments and the plurality of segments are bonded to the outer circumferential face of a base disk. The binding layer fixes the plurality of segments to the base disk. The adjoining segments each other are so constituted that parts opposed to the rotation direction of the grinding wheel are not bound to each other. The ratio (elasticity [GPa]/thickness [mm]) of the thickness of the binding layer to the modulus of elasticity of the binding layer is set to 9 GPa/mm or less. The modulus of elasticity of the binding layer is set to 2 GPa or less and the circumferential length of the segment is set to 40 mm or less.  This constitution distributes the stress applying to the grinding layer and the binding layer well balancedly so as to hardly cause the fracture in the both layers and drastically improve the comprehensive strength (binding safety rate) of the whole grinding wheel.

Abstract: PURPOSE:To obtain a highly reliable ultrasonic probe by a method wherein a plurality of high polymer piezo-electric bodies are laminated with polarization axes as opposed to one another in the direction and strips-shaped metal film are interposed on the opposed surfaces thereof as driving electrode to eliminate complication positioning of the strips-shaped electrodes at the lamination thereof. CONSTITUTION:A silver layer is evaporated on one side of a film produced by uniaxially stretching fluorine-containing high polymer such as polyvinylidene fluoride and the work is subjected to polarization under a high temperature and a high voltage to make a piezo-electric element 14. The silver layer provides a common electrode 15 by patterning. The piezo-electric body 14 thus obtained is bent with the electrode 15 outward to make the polarization axes as opposed to one another in the direction. Electrode material 18 such as Ag in the form of strips is inserted between the piezo-electric body 14 thus bent and pressed under pressure through an epoxy resin based adhesive 17 to obtain a laminated piezo-electricbody 13 as electrode 16 by adhesive lamination thereof. The long axis of the electrode 16 is made parallel with the direction of uniaxially stretching the piezo-electric body 14. This eliminates the complication in the position of the electrode 16 of the laminated piezo-electric body 14 while enabling a thickner film of the electrode 16 to obtain a highly reliable ultrasonic probe preventing disconnection or the like with a reduction in the loss.
