Title: Manufacture of hot rolled steel sheet free from surface flaw
Inventor: HAMAUZU SHIYUUICHI
IPC: B21B1/02
Filed: 1983-08-05
Abstract: PURPOSE:To prevent the surface in the vicinity of side edges of a rolling material from generating flaws by using, as a starting material, a slab having specific shapes at the corners of its cross section perpendicular to a rolling direction, in obtaining a hot strip by hot rolling a slab. CONSTITUTION:Each corner of the cross section perpendicular to the rolling direction of a slab to be used as a starting material, is champfered so that the dimensions (a), (b) in the directions of thickness and width of the slab satisfy the equations I , II (H: thickness of slab) and the relation of b/a>=1. The rolling of this slab is started by setting the rolling reduction in the width direction in hot rolling to the larger one of either the width spreading quantity in a rolling by horizontal rolling rolls or about 5mm. for each rolling reduction. Thus a hot rolled product is prevented from generating linear flaws in the vicinity of the end parts of its width direction.

Title: Clock margin setting system
Inventor: TANAKA TSUTOMU
IPC: G06F11/22
Filed: 1978-11-21
Abstract: PURPOSE: To make it possible to point out a defective part in the concrete by setting a clock margin to some circuits instead of margining the whole data processor by driving it by a high-speed pulse, etc.  
     CONSTITUTION: For a strict clock margin test, control signals G 1  and G 4  are applied to AND circuits 4-1 and 4-4. Consequently, clock pulse C 1  sent from OR circuit 5-1 to 1st FF circuit 6 is clock pulse CL 1  from phase adjustment circuit 2, and similarly clock pulse C 2  applied to 2nd FF circuit 9 is clock pulse CL 2  from phase adjustment circuit 3. Therefore pulses C 1  and C 2  are shown in Fig. (e). Since pulse C 2  leads C 1  in phase, pulse C 1  is applied to circuit 6 first and after time T 2 , pulse C 2  is applied to circuit 9. Since intervals of clock C 1  are time T 1  and T 1  is greater than T 2 , circuit 9 is limited in a shorter time than when circuits 6 and 9 are controlled at the same timing by pulses C 1  and C 2 .
