IPC: B24C9/00
Filed: 1989-06-19
Abstract: PURPOSE:To shorten the necessary time of a shot blasting stage and to improve the productivity by providing a driving source driving a screw conveyor with its rotation in the same direction. CONSTITUTION:The transfer speed of a work is decided by the rotations number control of screws 20, 21 by a driving source 3 and the inclinations of the screws 20, 21 set by the adjustment of an inclination adjusting member 8A. Namely, the work is continuously transferred at the transfer speed synchronized with the cycle time of a fore stage. Moreover, the work is forcibly reversed by the projecting part 2B for reversing the work in plural pieces provided with its projection on the outer periphery of the barrel part of a screw conveyor 2 and this reversal is repeated and so the projection of a shot becomes to be made easy and uniform for the whole area of the surface of the work. Consequently a proper blast having no projection unevenness can be executed in a short time, the transfer speed of the work is accelerated by synchronizing with the cycle time of a fore stage and the shot blast necessary time can be shortened.

IPC: H04L13/08
Filed: 1994-06-15
Abstract: PURPOSE:To shorten the delay time till a pertinent word is transmitted when a priority transmission word is generated in a CDT circuit. CONSTITUTION:At a normal time, a computer circuit 2 writes CDT transmission data in an FIFO memory 3 and a CDT serial signal S is transmitted in a latch 5 and a shift register 6.
