Title: Tape unloading device
Inventor: WACHI MASANARI
IPC: G11B15/665
Filed: 1989-05-08
Abstract: PURPOSE:To completely take up a tape by taking-up the tape by prescribed torque in the beginning while a tape guide is backed, judging whether the rotation of a supply side reel exceeds a prescribed area or not until it is completed to back the guide, further taking-up the tape when the rotation is less than the area and taking-up the tape by the prescribed torque even when the rotation is more than the prescribed area. CONSTITUTION:A command is sent from a controller 1 to a guide motor driving circuit 53 and a tape guide motor 52 is rotated. Then, a tape guide 51 is moved downward and a voltage switcher 9 is set to a voltage V1. Afterwards, a switch 8 is turned ON and a supply side reel 5 starts taking-up the tape. Until a tape unloading completion switch 54 is turned ON, the controller 1 counts a reel pulse from a rotation detecting circuit 3 and when the switch 54 is turned ON, the motor 52 is stopped. Next, the number of the pulses from the circuit 3 is compared with a prescribed number N of the pulses and when the number is more than the N, the switcher 9 is changed over to a voltage V2. Then, the tape is taken up for prescribed time. When the number is less than the N, the switcher is changed over to a voltage V3 and the tape is taken up within the prescribed time. Afterwards, the switch 8 is turned OFF and unloading is completed.

Title: Production of coke
Inventor: NOMURA SEIJI
IPC: C10B47/10
Filed: 1999-04-23
Abstract: PROBLEM TO BE SOLVED: To raise the ratio of non- or slightly caking coal used in a chambertype coke oven without detriment to the product quality by compounding non- or slightly caking coal pulverized to a particle size smaller than that of caking coal. SOLUTION: Non- or slightly caking coal is compounded with caking coal to give coal for coke making. Preferably, at least 80% of non- or slightly caking coal has a particle size of 2 mm or lower; and at least 70 % of caking coal has a particle size of 3 mm or lower. The degradation in the coke strength due to non- or slightly caking coal is caused by cracks derived from insufficient adhesion between non- or slightly caking coal and caking coal and by cracks derived from too large air bubbles occurring in non- or slightly caking coal particles. By decreasing the particle size of non- or slightly caking coal, the occurrence of coarse air bubbles is prevented, removing the factor for decreasing coke strength; and the uniformity is increased, increasing the contact area between non- or slightly caking coal and caking coal to increase the adhesive strength.  When the caking property of caking coal is enough, the contact area increases as the particle size of non- or slightly caking coal decreases, increasing the adhesive strength. Thus, the coke production cost is reduced and the range of selecting coal for coke making is widened.
