IPC: G11B5/738
Filed: 1993-03-19
Abstract: PURPOSE:To smoothen the surfaces of the projecting parts of a magnetic layer formed on a nonmagnetic thin film, to reduce the extent of levitation of a magnetic head and to increase recording density by forming pits in the nonmagnetic thin film in the form of concentric circles or a spiral. CONSTITUTION:Pits 32 are formed in a nonmagnetic thin film 14 on a nonmagnetic substrate 15 by etching in the form of concentric circles or a spiral. When a magnetic layer 16 is formed on the thin film 14 by sputtering or other method, a rugged magnetic layer 16 is formed in accordance with ruggedness by the pits 32 formed in the thin film 14. Since the surfaces 19 of the projecting parts of the thin film 14 are smooth, the extent of levitation of a magnetic head can be reduced and recording density can be increased.

Abstract: PROBLEM TO BE SOLVED: To judge the state of a device on a line at a glance with neither characters nor a graph by reading drawing data corresponding to state data out of a storage means when the state data is inputted through an input means. SOLUTION: Based on set mathematical expression data, constant data, and various state data inputted from the component mounting device through an I/F 19 and a communication line, a CPU calculates the operation rate of a component mounting device, reads the drawing data corresponding to the calculated operation rate out of a RAM 13, and displays it on a display 16 when the component mounting device is in operation. Further, when the component mounting device is not in operation, on the other hand, previously stored drawing data corresponding to the state data is read out of the RAM 13 and displayed on the display 16. Thus, the state of the device is represented with drawings, so the momentary actual operation state of the monitored device currently in operation and other states can be grasped almost instantaneously.

Title: Static type shift register and its controlling method
Inventor: MARUYAMA TADASHI
IPC: G11C19/28
Filed: 1985-03-26
Abstract: PURPOSE:To prevent the generation of output variation at the time of resetting while high speed action is executing, by making respective stages on master/ slave-sides one stage and by independently determining the output level by a switching means that acts in accordance with a reset signal. CONSTITUTION:The master-side consists of a clocked inverter 1 of a latch circuit and a positive feedback circuit 20, while the slave-side consists of a clocked inverter 8 of the P and Q channel gates 4 and 11 of a latch circuit and a positive feedback circuit 21. And, of both sides, the number of stages between the I/O terminals are made one. Accordingly, the data from a terminal D on the master-side is read in a terminal M accordance with a clock phi and inverse phi, and is accurately outputted to a terminal Q on the slave-side. Because the gate is of one stage, the shifting is of a high speed. On the contrary, when the reset signal R becomes H, a switching transistor TN 3 between the inverter 4 and the grounding is turned on, and the terminal Q is forcively maintained in '0', hence is not influenced by the impulse in the raising of the potential due to the shifting of the clock. Consequently, even if the action is made fast the generation of the output variation at the time of resetting is prevented.
