Abstract: PURPOSE:To eliminate the need for a space between an uncoiler and coil skid in which a coil material passes and the need for the instrument to be exclusively used for measurement by detecting the coil width by a coil detector provided in a coil car. CONSTITUTION:The distance Y from a reference line 7 to the end face of the coil is measured when the coil detector 6 detects one end face of the coil material 3 on a skid 4 after the coil car 5 starts moving in an un-coiler 2 direction. The measurement of the coil width W is started simultaneously therewith. The coil width W and the distance B from the coil end face to the center of the coil car 56 are calculated at the point of the time when the coil detector 6 detects the other end face of the coil material 3. The moving quantity Z of the coil car 5 is calculated from the resulted values W, B. The coil car 5 is run backward until the distance from the reference line 7 to the center of the coil car 5 attains Z. The coil material 3 is lifted in this position and is transferred onto the coil car 5 by a lifter.

Filed: 1993-12-06
Abstract: PURPOSE:To raise a heat efficiency by providing a first exhaust gas convergence means for collecting a combustion exhaust gas on a surface of the upstream side of a flow of the exhaust gas with respect to a water passing tube, and a second exhaust gas convergence means for exhausting the combustion exhaust gas from the first exhaust gas convergence means after collecting it at the downstream side surface of the exhaust gas flow with respect to the water passing tube. CONSTITUTION:As guide plates 5, 5 are each other made to be in a closely contact state, a combustion exhaust gas sent into a heat exchanging section 1b executes an inflow from an open section 51, contacts the upper face of a water passing tube 11 and executes an inflow among a guide plate 5, a water passing tube 11 and a fin 12. This combustion exhaust gas is exhausted from an open section 52 at the underside direction of the water passing tube 11, and contacts the underface of the water passing tube 11 at this time. Accordingly, a combustion gas is condensed, in a heat exchanging section 1b, by a contact action of the combustion exhaust gas over all circumferential periphery of the water passing tube 11 and the fin 12 and a heat efficiency is raised. A drain adhering to the upper section of an outside wall of the guide plate 5 enters the inside through a pierced hole 55 and flows downwards from the open section 52.

Title: Nitriding method for pressure control valve
Inventor: HORIMOTO TATSUO
IPC: F02M55/02
Filed: 1998-10-27
Abstract: PROBLEM TO BE SOLVED: To reduce the thermal distortion of a contact face of a valve or a valve seat of a pressure control valve and manufacture it with high precision by nitriding either of mutual contact faces of the valve and the valve seat at a specific nitriding temperature. SOLUTION: In a high pressure regulator 6 connected to a pipe connecting a high pressure pump with a delivery pipe in a gasoline engine of cylinder direct injection type, the hardness of a seat part which is a contact part of a valve seat 63 is set to Vickers hardness Hv 650, and the hardness of a seat part of a valve 64 capable of coming into contact with the seat part of the valve seat 63 is set to Vickers hardness Hv 900 by nitriding. When the valve seat of this valve 64 is nitrided, nitriding is done at a low temperature of 530 deg.C by salt bath nitriding to suppress the thermal distortion of the valve 64. Consequently, since the hardness of the seat part of the valve 64 is kept at Hv 900 which is above Hv 800, the wear of the valve 64 is reduced, and the sealing property can be improved even if the valve 64 turns.
