Title: Roll for rolling mill
Inventor: ISHIKAWA TOSHINORI
IPC: B21B13/14
Filed: 1990-01-24
Abstract: PURPOSE:To enable using under the conditions of high contact pressure at a prescribed position to the breadthwise direction of plate by providing a higher surface hardness in the corresponding position where is worked under the conditions of higher contact pressure to the longitudinal direction of the body part of roll by means of heat treatment technology. CONSTITUTION:In a roll which contact pressure always is higher in the vicinity of the same position to the longitudinal direction of roll, it is dissolved that wear and surface roughening are generated at an early stage at that position, the frequency of roll change that requires time and manual aid can be reduced and also the working effect of production facilities can be raised due to them. And, since the higher the hardness is, the higher the contact rolling fatigue strength is, the grinding quantity of each incorporated use that is conventionally based on the position of higher contact pressure to prevent fracture due to accumulative fatigue can be reduced and the consumption unit of roll is improved. Furthermore, since a partial wear in the longitudinal direction of the roll is small, the lowering of control ability for thickness accuracy in the breathwise direction can be prevented.

Title: Superconductor transistor
Inventor: SUZUKI HIROSHI
IPC: H01L29/68
Filed: 1989-01-20
Abstract: PURPOSE:To improve operation characteristics by arranging an insulator between a base region and a collector region, making tunnel current flow in an insulating layer, and eliminating a Schottky junction. CONSTITUTION:An insulator 4 is arranged between an emitter region 1 and a collector region 2 composed of superconductor. A collector region 3 composed of degenerated semiconductor of P-type or N-type is arranged, and an insulating layer 5 is interposed between the base region 2 and the collector region 3. The insulating layer is made so thin that tunnel current flows between the regions 2, 3. Since the superconductor 2 and the insulator 4 form a ohmic contact, a Schottky barrier is not generated. As a result, quasi-particle in the base region is injected into the collector region 3 without hindrance, via the insulating layer 5. By eliminating the Schottky junction in this manner, superconducting transistor excellent in operation characteristics can be obtained.

Abstract: PURPOSE:To send plural originals including a large original whose one page cannot be stored in a memory continuously while using the memory use mode. CONSTITUTION:Picture data from a scanner section 2 are read by a G3 control section 1 and the transmission is started while the picture data are being written in a memory 4 by a scanner control section 3. When the memory 4 is fully occupied before the end of read of a page, the scanner control section 3 writes succeeding picture data to an area of the memory 4 whose read is finished and an event of disabling re-transmission is set with respect to the relevant page. When a re-transmission request comes from an opposite terminal equipment at the end of transmission of one page, the G3 control section 1 sets the transmission of next page when the re-transmission is disable in response to the re-transmission of the page only when the re-transmission is allowed. In the case of sending a large original, the memory 4 acts like a single FIFO memory to send plural originals continuously while keeping the re-transmission function other than the large original.

Abstract: PURPOSE:To reduce noise due to the resonance of recording paper at the time of recording, by rotating paper press roller for holding recording paper between a platen and the paper press roller and feeding the same so as to obtain a paper feed amount more than that of the platen. CONSTITUTION:Recording paper is fed by a platen 11 and a paper press roller 16 but, by making the diameter of the pitch circle of a gear 13 slightly larger than that of the platen 11, the paper feed amount by the paper press roller 16 is made larger than that of the platen 11. Because recording paper is wound around the platen 11 is a wide area, the feed force of the recording paper of the platen 11 becomes larger and the paper feed amount is controlled by the rotation of the platen 11. The paper press roller 16 is rotated while increased in its speed to generate force for tensioning the recording paper upwardly. As a result, the gap between a recording position and the paper press roller 16 is reduced and the roller 16 rotates while slips on the recording paper. Because the recording paper is closely contacted with the platen 11, no resonance is generated and noise is reduced.
