Title: Magnetic bubble memory device
Inventor: KASAHARA SHINICHI
IPC: G11C11/14
Filed: 1989-03-20
Abstract: PURPOSE:To correct the warp of a mold frame, and to prevent the characteristic deterioration of a chip when a chip assembly is inserted to a coil assembly by providing a projection, which corrects the warp of the mold frame of the chip assembly, at the center of a mold frame beforehand. CONSTITUTION:A projection 8 is provided at the center of a mold frame 3 of a chip assembly 4, and the warp generated at the time of molding the mold frame 3 with the use of a resin is corrected when it is inserted to a through hole 7 of a coil assembly 6. For the height of the projection 8, the height of the mold frame including the projection is made equal to the height of the through hole 7 of the coil assembly 6, and the shape of the projection is made into a gentle slope in the inserting direction so that the coil assembly 6 may be easily inserted to the through hole 7. Thus when the chip assembly 4, whose projection 8 is molded to the mold frame 3, is inserted to the through hole 7 of the coil assembly 6, even when the mold frame 3 is warped, since the projection 8 is pressured by the wall of the through hole 7, the warp is corrected. Thus the characteristic deterioration of the chip can be prevented.

Title: Transmission torque control device of four-wheel drive vehicle
Inventor: WATANABE KENICHI
IPC: B60K17/348
Filed: 1994-04-04
Abstract: PURPOSE:To improve braking performance by carrying out torque allocation control precisely at braking time. CONSTITUTION:A control unit controls an electric current (i) according to a control line 1b1 by the third control manual M3 when it receives a brake signal from a brake switch. Since the electric current (i) is controlled in the control line 1b1 of the map M3 so as to become fairly larger than that when ordinary control is carried out, operating oil pressure generated by an oil pressure control valve becomes also large. Thereby, at braking time, since transmission torque to the small side of a transmission torque quantity is controlled so as to be increased in proprortion to a difference in rotating speed between front and rear wheels, control is approached to a four-wheel drive condition in a condition where driving forces to four wheels are equallized to each other as the difference in the rotating speed becomes large. That is, a clutch is almost put in a complete fastening condition, and a torque allocation quantity to rear wheels is increased, so as to improve braking time stability.

Abstract: PURPOSE:To ensure that jamming with the form is prevented if the tip of the form is located between a form discharge roller and a printing head by transporting the tip of the printing form to a position between the form discharge roller in a transport path and a printing head, parking a form transport roller from the transport path, and printing the form starting with its tip. CONSTITUTION:When the form 1 is printed on the area within one inch from the tip, it is transported to a position between a form discharge roller 5 in a transport path and a printing head. Then the form transport roller 5 is parked from the transport path to start printing. Consequently, the tip of the form is prevented from running into the form discharge roller 5 and it is ensured that the form is printed on the area within one inch from the tip 1. In addition, the time required for parking the form transport roller 5 in the transport path depends on the specified amount of the form 1 is passable through the form transport roller 5. If the line is fed by the specified amount, the form transport roller 5 returns to its home position, holding the form with a platen 4. Thus the form is prevented from swaying between the printing head 3 and the platen 4, and the printing action of the printing head 3 is not obstructed.
