Title: Method for manufacturing case constituting member
Inventor: HIRAGUCHI KAZUO
IPC: B29L22/00
Filed: 2001-05-15
Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing a case constituting member with such advantages that design properties are not impaired by a gate mark and a weldline is prevented from being formed. SOLUTION: This method for manufacturing a case constituting member is employed for manufacturing the lower face sheet 36 of a disc cartridge having an opening 14 for accessing a disc medium. That is, the tip position of a gate through which a molten resin is injected into a mold is set down to the inside rather than the outside surface of the finished product of the lower face sheet 36 on a line 166 dividing the lower face sheet 36 into halves passing through an opening 14. consequently, the tip faces of the injected molten resin reach the edge of the opening, and at the same time, the tip faces of the molten resin are prevented from running into each other, so that the formation of the weldline can be avoided. In addition, the gate mark to be formed in the lower face sheet 36 is generated in a recessed part to be formed on the outside surface of the lower face sheet 36.  For this reason, the gate mark is inconspicuous and the recessed part can be used as a region having a function to a drive device.

Title: Stage system and its driving method, exposing system and exposing method, and device and its fabricating method
Inventor: TANAKA KEIICHI
IPC: H02P25/06
Filed: 2001-05-18
Abstract: PROBLEM TO BE SOLVED: To enhance positional controllability of a stage without requiring an extra reaction cancel mechanism. SOLUTION: When currents having different phases are supplied while being superposed, linear motors (114', 116') generate a force in the direction of X axis and a force in the direction of Y axis independent from each other. When a stage WST1 is driven integrally with a move in the direction of Y axis by a linear motor (stator 110a), reaction of the driving force acts on the stator 110a, but when current control is performed such that the linear motors (114', 116') generate a force for canceling that reaction in the direction of Y axis, the reaction can be canceled. Reaction cancelation has no relation with the magnitude of the driving of the stage in the direction of Y axis. Consequently, positional controllability of the stage can be enhanced without requiring any extra mechanism for canceling reaction of the driving force of the stage in the direction of Y axis.

Abstract: PROBLEM TO BE SOLVED: To facilitate transmission control for a plurality of traveling modes formed of the combination of an engine and a motor. SOLUTION: When a clutch C2 is faultily fixed while a front drive motor 34 outputs torque to a drive shaft 14 of a front wheel 12 via a clutch C1 by fixing the clutch C1 and releasing clutches C2, B1, a crankshaft 30 of the engine 28 is brought into an independently rotatable state by releasing the normal clutch C1 by commanding to transmit to a neutral mode that releases the clutches C1, C2, and then, the engine 28 is started by commanding to transmit to a traveling mode that is formable in a state of the fault fixing of the clutch C2, to enable an operation under a torque-amplified traveling mode. Thus, since there is no need for a particular process for refuge travel that is necessary in abnormal clutch conditions, the transmission control of the traveling mode is facilitated.
