Title: Detection of average number of revolution of motor
Inventor: FUJINO MASAHARU
IPC: G01P3/481
Filed: 1988-01-21
Abstract: PURPOSE:To accurately detect the average number of revolutions of a motor regardless of the number of revolutions of the motor and the interval length of the detection timing by making the frequency of a reference clock higher enough. CONSTITUTION:An encoder pulse 9 proportional to the number of revolutions is generated 2 with the rotation of a servomotor 1 and a rising edge of the encoder pulse 9 is counted 3. The rising edge of the reference clock 11 generated by a crystal oscillation circuit 4 is counted by a 2nd counter 5. At this stage, a value 12 of the counter 5 is latched 6 with a timing which is coincident with an input to a 1st counter 3, and this latch timing 18 is delayed until the time when the value 12 of the counter 5 is put in order after the internal operation in the counter 5 is finished by a D flip-flop circuit 15 and a delay circuit 16. A value 10 of the counter 3 and a value 13 latched by the value 12 of the counter 5 are read into a CPU7 every time when a detection timing 14 generated from a timing generating circuit 8 is inputted, and wherein computed according to a program 20, thus the average number of revolutions is obtained.

IPC: G11B5/72
Filed: 1995-01-27
Abstract: PURPOSE:To obtain a magnetic recording medium excellent in chemical durability of the magnetic layer by forming two protective layers having mutually different compsns. CONSTITUTION:An underlayer 2, a magnetic layer 3, a 1st protective layer 4a, a 2nd protective layer 4b and a lubricative layer 5 are successively formed on a nonmagnetic substrate 1 to obtain the objective magnetic recording medium. The 1st protective layer 4a is made of a Cr film having 50Angstrom  thickness and the 2nd protective layer 4b consists of a metal oxide film 6 using silicon oxide as the metal oxide, fine silica particles 7 having 300Angstrom  average particle diameter and fine silica particles 8 having 3,000Angstrom average particle diameter dispersed in the film 6. In the 2nd protective layer 4b, the thickness of the metal oxide film 6 in the region where the fine silica particles 7 and 8 do not exist is 150Angstrom , the existence density of the particles 7 is 20 per 1mum<2> and that of the particles 8 is 0.1 per 1um<2>. Since the 1st protective layer 4a prevents moisture contained in the open air from entering the magnetic layer 3 through the 2nd protective layer 4b, the chemical durability of the magnetic layer 3 is maintained and spacing loss can be prevented.
