Title: Manufacture of thick steel plate
Inventor: FUJIBAYASHI TERUO
IPC: B21B1/38
Filed: 1998-03-18
Abstract: PROBLEM TO BE SOLVED: To provide a method capable of stably manufacturing online a steel plate whose bar cutting distortion is small and moreover which has homogeneous quality over the whole steel plate. SOLUTION: Cooling having a temperature distribution in the width direction of a plate is executed so as to compensate the quantity of temperature drop in the vicinity of a plate end part which generates from a heating furnace to the finish of rough rolling and temperature drop in the vicinity of the plate end part which is estimated to generate at the time of finish rolling with a cooling device 2 which is provided between a roughing mill 1 and a finishing mill 3. Thus, a temperature in the width direction of the steel plate becomes uniform after finish rolling is completed. In such a state, accelerated cooling is executed with an accelerated cooling device 5 under a cooling condition uniform in the width direction.  Since a temperature in the width direction of the steel plate at the inlet side of the accelerated cooling device 5 is uniform, the steel plate is uniformly cooled in the width direction with an accelerated cooling device 5, and an internal stress is not generated. Therefore, the steel plate whose bar cutting distortion is small and which has homogeneous quality is manufactured.

Title: Detector of local electric discharge on electric apparatus
Inventor: UMEMURA TOKIHIRO
IPC: G01R31/12
Filed: 1990-04-04
Abstract: PURPOSE:To surely detect a local discharge by simultaneously detecting signal components corresponding to interlinked magnetic field components arranged near the winding and a decomposed gas produced by the local discharge. CONSTITUTION:When an outcoming radio wave or noise are generated, they come to a local discharge sensor 5, which most possibly responds thereto. But, a signal is not outputted from a decomposed gas sensor 7 in this case by the reason that no decomposed gas is produced, therefore, the signal is not outputted to a display device 11 for abnormal signal through a signal processing device 10. On the other hand, the sensor 7 responds when the decomposed gas is produced in the sensor 7 by a primary factor other than the local discharge and is responded. In this case, however, an abnormality is not displayed the same as before, since the sensor 5 is not responded. Thus, the local discharge only can be surely detected by the combination of the sensor 5 and sensor 7.

Title: Exposure scanning device
Inventor: ARAKI KEISUKE
IPC: G03G15/04
Filed: 1988-04-13
Abstract: PURPOSE:To prevent or reduce the deterioration of an exposed picture by forming the guide surface of a transparent original carrying guide for slit exposure to a curved surface corresponding to the curvature of a recording medium. CONSTITUTION:An original 3 is transferred by means of a carrying roller system 4 while the original 3 is press-contacted with the concave surface 2 of a body on the upper surface of an original supporting plate 1. The surface of the original 3 on the original supporting plate 1 is illuminated with a lighting lamp 7 and the light of the picture of the original forms an image on a photosensitive drum 5 through a lens array 6. Since the concave surface 2 of the body on the plate 1 is made optically symmetrical against the drum surface of the drum 5, the picture of the original 3 formed on the drum surface of a recording medium becomes picture light from the curved surface corresponding to the curvature of the drum surface the image-formed picture plane is matched up to the drum surface of the recording medium. Therefore, the image forming and superposing characteristics can be prevented from being deteriorated even if the curvature of the drum surface becomes larger.

Abstract: PURPOSE:To further increase the luminance of an electron gun, which contains a monocrystal LaB6 cathode, by enabling a single beam to be obtained constantly even when the bias between the monocrystal LaB6 cathode and a Wehnelt electrode is made shallow. CONSTITUTION:A monocrystal LaB6 cathode 1 is set to have its given axial direction corresponding to the direction of electron discharge, and is formed by working the end of a square prism 2 into a circular cylinder having a small diameter. Here, the axial direction[100],[210]or[310]of the cathode 1 is adjusted to correspond to the direction of electron discharge. The extreme end of the cathode 1, that is to say, the end of a circular cylindrical part 3 is  worked into a flat to say, the end of a circular cylindrical part 3 is worked  into a flat surface, and is made to have an acute angle.
