Abstract: PROBLEM TO BE SOLVED: To prevent a disk cartridge from colliding against a magnetic head when the disk cartridge is inserted into a disk holder and also to contrive the space saving. SOLUTION: The collision preventing mechanism 81 of the disk cartridge is constituted of a protector 82 extendedly provided in the insetting direction of the disk cartridge, a protector arm 83 attached to the rear end part of the protector 82, and a torsion spring 84 for pressing the protector 82 to be in the erecting state. The protector 82 before the disk cartridge is inserted is held so that sliding contact part 89 for the disk cartridge is in the erecting state by the spring force of the torsion spring 84. By this arrangement, the disk cartridge 96 inserted into the disk holder 12 is slid in contact with the sliding contact part 89 for the disk cartridge of the protector 82, and the height position of insertion is controlled. Thus, the end part of the disk cartridge 96 on the inserting side is prevented from colliding against the lower side magnetic head 16.

IPC: F16J15/02
Filed: 1990-11-30
Abstract: PURPOSE: To prevent lowering of an adhesion degree due to deformation by providing a plurality of conductive wire coils inclined along the center line, applying pre-load to the coils so that adjacent coil spacing is decreased, and limiting the passage of electromagnetic energy with a wavelength greater than a selected value. CONSTITUTION: An electromagnetic shield gasket 30 having elasticity in the axial direction has plural coils 32 which are connected to each other so that the rear ends 34 are along the inside diameter 36 of the gasket 30 and the front ends 38 are along the outside diameter. A back angle 42 determines the arrangement of the rear end 44 of each coil with respect to a line 44 vertical to the center line 46, and determines a front angle 49 presenting the front end 38 of each coil. The back angle 42 determines the operating elastic range, and the gasket shows fixed force to the deformation. Thus, a small change, eccentricities and deformation caused by temperature and environmental conditions between the engagement parts do not exert any influence on loading and sealing force so that the gasket can be used as an electromagnetic shield gasket.

IPC: G06F9/445
Filed: 1996-12-03
Abstract: PROBLEM TO BE SOLVED: To facilitate the change of a software by locking a protection controller output from the reception start of a program module transmitted from a program storing device by means of a protection controll till the execution start. SOLUTION: A control means 27 for locking an external output during the reception of the program module is provided. Since an external output signal 12 and a during software change signal are logical zero at the time of normality, the external output 13 of the controller becomes logical zero. When the external output signal 12 as the result of a software operation becomes logical one, the during software change signal is logical zero and the output of a NOT circuit 271 is logical one so that the output of an AND circuit 272 is logical one and the controller 20 executes the external output. Since the during software change signal becomes logical one during changing the software, the output of the NOT circuit 271 is logical zero, the output of the AND circuit 272 becomes logical zero even when the external output signal is logical one and the external output 13 of the controller is locked.

Title: Electrically erasable nonvolatile memory
Inventor: HAYASHIBARA IZUMI
IPC: G11C17/00
Filed: 1991-12-24
Abstract: PURPOSE:To remarkably increase the number of rewriting times and a life by obtaining a threshold value corresponding to a predetermined current flowing to a sample cell and deciding '0' or '1'. CONSTITUTION:Sample cells 20, 22 are provided. When a predetermined gate voltage is applied to the cells 20, 22 of a writing state, a first current flowing in the cells is obtained. When a predetermined gate current is applied to the cells 20, 22 of an erased state, a second current flowing in the cells is obtained. A threshold value corresponding to an intermediate current value between the first current of the writing state and the second current of the erasing state is obtained, and '0' or '1' is decided by using the threshold value. Thus, a threshold value is varied in the memory cell as a time is elapsed. When this change with time is compensated, the number of rewriting times can be remarkably increased from 10<6> or less to 10<7> times or more.
