Title: Manufacture of stepped roll
Inventor: DEWA AKIO
IPC: B23P9/00
Filed: 1986-02-17
Abstract: PURPOSE:To prevent a stepped roll from being deformed without the hardness of a hard layer being lowered, by setting the annealing temperature of a stepped roll to be plated with Ni-P composite platings to a value in a range from 250 to 500deg. C after high-frequency hardening, and by setting the hardening heat treatment temperature of the stepped roll after the plating to a value which is lower than the above- mentioned temperature by about 150deg. CONSTITUTION:A stepped roll to be plated with composite platings using an Ni-P matrix, is produced by a process comprising an angle-roughening step 11 for a roll material 10, a high frequency hardening step 12, an annealing step 23, an angle finish- polishing step 14, an Ni-P composite plating step 17 for the angle surface of the material, a hardening heat treatment step 28 and inspection and the like steps 16. In this arrangement, the annealing temperature is set to 250 to 500deg. C during the annealing step, and the hardening heat treatment temperature is set to a temperature equal to the annealing temperature or higher than that by about 150deg. C. As a result, the effect of the hardening heat treatment is not altered so that the hardness of the roll does not lower while the generation of run-out may be restrained below 20mu, and therefore, no polishing step for correction may be required, thereby it is possible to reduce the number of steps and to prolong the life of the stepped roll due to avoiding reducing the thickness of the Ni-P composite plating layer.

Title: Crushing apparatus
Inventor: ITO MAKOTO
IPC: H02P5/00
Filed: 1990-02-15
Abstract: PURPOSE:To manufacture a product of high quality without stopping an operation by providing a stall detector for inputting a rotating speed detection signal of a second motor or a crusher, comparing it with a preset reference value, and outputting its difference to a first inverter as a speed control signal. CONSTITUTION:When predetermined time is elapsed, a stall detector 8 which is turned ON simultaneously upon operation of an inverter 5A sets its function valid. If this speed signal is compared with a reference value set by a setter 9 to become smaller than a reference value, its difference is input as an inverter 5B. Thus, the inverter 5B reduces its output voltage and frequency, and the rotating speed of a motor 3B is reduced correspondingly to decelerate the speed of a conveyor 4. Then, the quantity of a rock to be supplied to a crusher 1 is reduced to decrease the load of the crusher 1 to provide a crushing apparatus which can prevent an irregularity in a crushed product due to stalling, stopping, stop of operation of the crusher 1.
