摘要： PROBLEM TO BE SOLVED: To provide a draw forming device which restrains deflection at the center of a blank material set in a mold and minimizes dimensional variations in a formed product.
SOLUTION: In the draw forming device 11, a blank holder 16 comprises a first retaining means 32 which binds the outermost circumference 31 of the blank material 15, and a second retaining means 33 which is placed inward of the first retaining means 32. Due to the descent of a double-acting press 17 the retaining position B1 of the first retaining means 32 is made a position where the first retaining means 32 holds the blank material 15 ahead of the second retaining means 33, and a position where the double-acting press 17 descends further is made the retaining position B2 of the second retaining means 33. A mold (cope) 27 is supported slidably by the second retaining means 33 and is placed away from an inner slider 21. The first and second retaining means 32 and 33 are fixed in an integrated manner to an outer slider 22 which is placed outward of the inner slider 21.

摘要： PROBLEM TO BE SOLVED: To eliminate backlash between divided cores, in a stator core assembled by fitting to a recessed groove at the other end of a yoke portion of each divided core with projections at one end of the york portion of each divided core arranged adjacently in a peripheral direction. SOLUTION: At an intermediate portion of a projection 6 and a recessed groove 7, straight portions 6a, 7a extending with a constant width in a normal line direction of each end face of the york portion 2, and constricted portions 6c, 7c which are slightly narrow in width than the straight portion, are formed in adjacent to a portion close to the end portion of the yoke of the straight portion. When pressing in the projection 6 to the recessed groove 7 from the normal line direction, groove walls 2a, 2b at the outer radius side and inner radius side of the recessed groove 7 are deflected in an elastic region, and a straight portion 6a and a constricted portion 6c of the projection 6 are elastically just tightened at the straight portion 7a and constricted portion 7c of the recessed groove 7. Also, the recessed groove 7 is formed in such a manner that the width W1 of the groove wall 2a at the outer radius side becomes equal to the width W2 of the groove wall 2b at the inner radius side on the boundary line d perpendicular to the normal line direction between the straight portion 7a and the semicircular portion 7b.

摘要： PROBLEM TO BE SOLVED: To decide whether or not an oxygen concentration sensor is abnormal during driving by confirming that an output signal of the oxygen concentration output sensor does not show rich and lean reversals for air-fuel ratio in an air-fuel ratio feedback control drive state. SOLUTION: A CPU 6 determines a fuel injection time with the use of a drive parameter and the number of revolution of an engine. Fuel is injected into an engine 2 during only the fuel injection time. Oxygen concentration is detected by an oxygen concentration sensor 16 from a combustion exhaust gas. By repeating the process, an air-fuel ratio of a supplied mixed gas is fed back to control a theoretical air-fuel ratio. In a fail-safe process, the CPU 6 first decide whether or not a drive state of the engine 2 is in an air-fuel ratio feedback control area and then decides whether or not the drive state is in a rich drive area. When an output level of the oxygen concentration sensor 16 indicates a lean air-fuel ratio, it is decided whether or not a counted value of an anomaly decision counter is larger than a predetermined value, thereby deciding the oxygen concentration sensor 16 as abnormal.

摘要： PROBLEM TO BE SOLVED: To comparatively quickly fix a rotation angle position from the starting of revolution by deciding a rotation angle position except a specified one after either one specified rotation angle position of a plurality of specified rotation angle positions of a first rotation body is decided. SOLUTION: A first rotation body 2 interlocking with revolution of a crankshaft 6 generates crank pulses from an electromagnetic pickup 4 for every revolution by 30 deg. and a second rotary body 3 mounted on a camshaft 7 interlocking and revolving at the half speed of revolution of the crankshaft 6 generates cylinder pulses from an electromagnetic pickup 5 at intervals of rotation angles 60 deg., 300 deg. and 360 deg.. The cylinder pulses are stored in a storage element 18a by synchronizing with crank pulses and are further shifted to the side of a storage element 18C. After a plurality of specified rotation angle positions of the rotation body 2 are decided by detection results from this time of the presence or absence of cylinder pulses up to plural number of times before for every generation of crank pulses, the number of generation of crank pulses is counted, and a rotation angle position of the rotation body 2 except a specified rotation angle position is decided.

摘要： PURPOSE:To execute forming to an inner plate without detaching a die metallic mold for forming an outer plate from a hydraulic forming device. CONSTITUTION:A blank for an outer plate is pressed against a die metallic mold 2 for forming an outer plate by fluid pressure and the outer plate of a hull is formed, and thereafter, in the die metallic mold 2, a core die 7 is set, or the core die 7 is set on the outer plate leaving the outer plate in the die metallic mold 2 as it is, and a blank for an inner plate is pressed against the core die 7 by fluid pressure and an inner plate 1b of the hull is formed. In the core die 7 for forming the inner plate, an air vent hole 7b is formed, and air enclosed between the inner plate 1b and the core die 7, at the time of forming the inner plate, is exhausted. The core die can be handled easily since it is small in size and light in weight, and also, the cost of the core die is inexpensive and the production efficiency is improved. Moreover, in a state that the core die is housed in the die metallic mold for forming the outer plate, the die not used can be stocked, therefore, the stock space of the die can be curtailed.
