Abstract: PURPOSE:To produce a compact wound endless wire used for a paper machine and facilitating the mounting work of the endless wire on the paper machine, and to provide a method for winding the endless wire. CONSTITUTION:The wound endless wire 5 is prepared by inserting a steel pipe 2 into the end of an endless wire 1 in the width direction, inserting a core 3 having a smaller diameter than that of the steel pipe 2 into the other end of the endless wire 1, bringing a core 4 having the same diameter as that of the core 3 into contact with the core 3 from the upper side of the wire 1, rotating the core 3 round the core 4, while winding the endless wire 1 on the core 3, then winding the core 4 round the core 3, successively and alternately rotating the core 3 and the core 4 on each other and simultaneously winding up the endless wire 1 on the peripheral surface common to the core 3 and the core 4. When the wound endless wire is packaged, the cores 3 and 4 are pulled out. When the wound endless wire is mounted on a paper machine, the wire is simply developed only by suspending the steel pipe 2 with a crane.

Title: Optical disk recording and reproducing device
Inventor: TAKEDA KATSUMI
IPC: G11B7/004
Filed: 1987-04-08
Abstract: PURPOSE:To reduce cross-talks from adjacent tracks so as to realize high recording density, by changing the rate of birefringence so that the quantity of light from a desired track can be made almost maximum among the reflecting rays of light from an optical disk made incident on a photodetector means. CONSTITUTION:Each track 15a-15c of an optical disk 1 is formed in such a way in advance that the rate of birefringence of the adjacent tracks, for example, 15a and 15b can be made relatively different from each other. Then birefringent properties are given and the rate of birefringence of the tracks is changeable, and components vibrating in a special direction are extracted from the reflecting light from the tracks. The extracted components are made incident on a photodetecting means. Since the angle of the plane of polarization of the reflecting light from a desired track is different from that of its adjacent track, the reflecting light can be separated from that from the adjacent track. Therefore, when the rate of birefringence is changed so that the quantity of the reflecting light can be made almost maximum, most of the reflecting light can be led to the photodetecting means, but the reflecting light from the adjacent track is not led to the photodetecting means. Accordingly, the recording density can be increased, since cross-talks from the adjacent track can be reduced.

Title: Electronic balance
Inventor: YANO SHIYOUZOU
IPC: G01G23/10
Filed: 1978-07-10
Abstract: PURPOSE: To increase the accuracy of weighing by giving the average calculation as soon as the vibration of the balance becomes within the limit of steadiness and the dispersion of the data becomes within the allowable range.  
     CONSTITUTION: When the sample is put onto the balance, data input control part starts immediately sampling of the data. Thus the weighing value is sampled with a fixed time interval shorter than the half cycle of the balance vibration and then memorized in sequence into memory mechanism 8. Comparator 9 compares the sampling value with the memory value groups of mechanism 8 in sequence. And in case more than one of the memory groups feature the fluctuation difference which is over the fixed fluctuation allowable range, signal S is transmitted to part 6 from comparator 9 to erase the entire memory groups. This sampling the comparing action are repeated. And when it is decided that no memory value having the fluctuation difference of over the fixed level exists among the memory groups, the each memory value of the memory groups is averaged through operator 12 to be displayed.
