IPC: B21B13/14
Filed: 1981-11-24
Abstract: PURPOSE:To simplify the construction of the thrust receiving mechanism of rolling mills extremely by changing the crossing angle of the shafts of upper and lower bear roll groups in the idling stage when a plate material is not rolled and after the preceding end of the plate material is gnawed. CONSTITUTION:The shafts of upper backup and upper wrk rolls 3, 1 are maintained approximately parallel to provide an upper bear roll group, and likewise a lower bear roll group is formed with lower backup and lower work rolls 4, 2.

Large thrust forces are generated in the kiss roll state during idling. In the stage of idling, the crossing angle of the upper and lower roll groups is set at a sufficiently small angle including 0 deg. at which the thrust force are sufficiently small, and after the preceding end of the plate material is gnawed, the above-described crossing angle is changed down to the angle suited for rolling.

Title: Japanese language input system
Inventor: AZUMA KENJI
IPC: G06F17/22
Filed: 1988-07-26
Abstract: PURPOSE:To make the keying of plural times unnecessary by keying a shift key and 'N' at the same time as 'n' of HIRAKANA (cursive Japanese syllabary) is inputted. CONSTITUTION:At the time 'n' of HIRAKANA is inputted, the shift key and 'N' are keyed simultaneously. Since the shift key becomes the key of state inverting function from a 'capital letter' to a 'small letter', which of a capital letter state/small letter state the present state is watched and stored by a state storing means 3. When a character determining means 4 acquires one character after sending a one-character acquisition request to a one-character acquiring means 2, it inquires of the state storing means 3 about the present state, and if an English letter is 'n' and the state is the 'capital letter state', it decides that the input of 'n' is completed, and if the English letter is 'N' and the state is the 'small letter state', it decides that the input of 'n' is completed. Thus, the input of 'n' of HIRAKANA is completed through the keying of one time.
