Title: Yoke of high magnetic permeability and flux density
Inventor: MOMOSE KENICHIROU
IPC: H01F3/02
Filed: 1978-08-28
Abstract: PURPOSE: To provide a yoke of high magnetic permeability and saturated flux density, by stratifying nickel-iron alloy plates with metal plates whose initial permeability and saturated flux density are not less than prescribed values.  
     CONSTITUTION: Appropriate quantity of nickel-iron alloy plates of 70 to 90% in nickel content are stratified with appropriate quantity of plates of metal such as pure iron, iron alloy, iron-nickel alloy or iron-cobalt alloy whose initial magnetic permeability is not less than 10000 and whose saturated flux density is not less than 10000 G, thereby manufacturing the yoke. Since the saturated flux density B s  of the metal plates such as the pure iron and the permeability μ o  of the nickel- iron alloy plates of 70 to 90% in nickel content are high, the yoke having high saturated flux density and high permeability is obtained. The thickness of the stratified plates is appropriately selected to obtain desired characteristics for the yoke.

Filed: 1996-04-02
Abstract: PROBLEM TO BE SOLVED: To decrease a beam spot on a glass substrate and to realize high- density recording by forming a transparent dielectric film on an optical glass plate to change the phase of a laser beam which transmits the optical glass plate. SOLUTION: A phase compensating plate 20 is produced by forming a transparent dielectric film 22 having uniform film thickness by vapor deposition on an optical glass plate 21. The transparent dielectric film 22 is formed to have 2ρ diameter concentric to the iris of an objective lens 19 having the iris diameter (α) so as to change the whole phase of the laser beam which transmits the transparent dielectric film 22. Thereby, the transparent dielectric film 22 shifts the phase of the transmitted light to produce the area where the phase difference is changed.

Abstract: PURPOSE:To improve the processing efficiency of a memory protection system for tasks by producing the memory protection data only when a task is executed at first, storing this produced data into a load module for tasks and then reading out the protection data to use it when the control is shifted to a current task. CONSTITUTION:A memory protection data saving area 2 is provided in a load module 10 at every task. Then the memory protection data is produced and a set initial routine is carried out only when the control is shifted to a due task at first. The memory protection data is taken out of the area 2 when the control is shifted to a current task. Then the protection data is set to a memory protection register which is controlled by an operation system. Thus it is not required to produce the memory protection data nor to set it to the memory protection register at every execution of a task. Consequently, the overhead can be eliminated for such processes where the memory protection data is produced and set to the memory protection register, and the overall system processing efficiency is improved.
