Title: Magnetic head stepping servo system for a tape drive unit
Inventor: GUTTORM RUDI
IPC: G11B5/588
Filed: 1992-12-30
Abstract: 5 n7 A device for positioning a magnetic head to an operative position relative to a selected track of a multi-track magnetic tape in a magnetic tape write/read device. A magnetic head is disposed at one end of a magnetic head carrier while the opposite end of the head carrier is axially movable along a shaft fixed to the tape recorder housing frame. An inchworm-type servo system is provided which has two clamping devices arranged stacked axially along the shaft and a positioning device connected between the two clamping devices which can be altered in length to move the clamping devices toward or away from each other. By alternatingly clamping the two clamping devices to the shaft and altering the distance between the two clamping devices in coordination, the servo system can crawl up and down the shaft to position the magnetic head. In another mode of operation, the clamp which mounts the head carrier is left unclamped with respect to the shaft, the opposite clamping device is clamped with respect to the shaft, and the extending device is allowed to expand or contract over its operable range to minutely position the head with respect to the tape. In the preferred embodiment, the clamping devices and the extending devices are piezoelectric elements which receive a voltage potential to correspondingly expand or contract. By contracting the clamping devices are actuated to clamp tightly to the shaft to prevent axial movement.

Abstract: A semiconductor memory device with a redundancy configuration with a higher corrective efficiency is disclosed. Primary memory cell arrays 3a, 3b, and 3c are arranged in memory cell blocks a, b, and c. Spare memory cell arrays 2b and 2c are arranged in the memory cell blocks b and c. When the address of an address signal supplied agrees with the address of a defective primary memory cell in one memory cell block, a spare memory cell in the other memory cell block is selected for such a defective memory cell. Even if a word line of the primary and a word line of the spare memory cells are selected at the same time, it is possible to access read data in a nondestructive manner. This achieves a high-speed word line activation as well as an improved corrective efficiency. The provision of a row decoder that connects a primary word line to a spare word line with a shared decode line prevents the increase of the area of memory chips due to the arrangement of a spare memory cell.

Abstract: A system for determining the optimal circuit design simulator schedule for debugging a digital electronic circuit design. The system characterizes all available circuit design simulators in terms of several parameters reflecting simulator speed and the time required to discover, isolate and fix a design error (bug). A cutover point is established for any pair of available simulators on the basis of these parameters. One simulator is progressively more efficient than the other beyond this cutover point, which is the desired time for scheduling substitution of the more efficient simulator during the debugging process. The system also permits "what-if" evaluation of alternative debugging strategies in advance by creating alternative schedules in response to various characteristic parameters.

Abstract: An image display apparatus reduces the possibility of occurrence of minor discomforts such as headaches, eyestrain, fatigue and the like in users. A symbol indicating distance such as 1m, 3m, or ∞ is displayed on an outer periphery of a virtual image adjusting knob. When the user aligns a mark on the virtual image position adjusting knob (18) with a position corresponding to one of the predetermined symbols, the virtual image is set so as to be displayed at a position corresponding to the symbol. Consequently, the user can more easily recognize the displayed position of the virtual image so that the generation of a minor discomfort due to long term use which is more than necessary of the image display apparatus is substantially reduced.
