IPC: G11B5/596
Filed: 1988-07-13
Abstract: PURPOSE:To suppress the influence of erase crosstalks so that the positioning of the magnetic head of a floppy disk can be controlled certainly without error by executing the control based on servo information read out from a magnetic recording medium. CONSTITUTION:A read/write gap 10 and erase gap 11 are provided to an erase leading type magnetic head in such a way that the gap 11 precedes the gap 10 in the running direction A of a magnetic recording medium. Moreover, a floppy disk device produces a control signal for positioning the head 20 to a required position at a servo circuit 21 based on a servo signal read out from the head 20. The magnetic head 20 is moved to the required position by outputting the control signal produced at the circuit 21 to a carriage drive control circuit 22 and controlling the driving of a carriage 23 mounted with the head 20. In addition, the carriage 23 is controlled by previously storing a prefixed interval T between a preceding pattern A and another pattern C immediately following the pattern A in the magnetic recording medium.

Title: Straightness measuring instrument using optical interference
Inventor: KONDO MICHIO
IPC: G01B11/30
Filed: 1989-07-06
Abstract: PURPOSE:To measure straightness with high accuracy by detecting the quantity of variation in optical path length between measurement light and reference light obtained by splitting laser beam. CONSTITUTION:Laser beam emitted from a laser beam source 10 is made incident on a constant polarization optical fiber 20 through a polarization BS(beam splitter) 12, a Faraday rotator 14, a deflection BS 16, and a condenser lens 18. Then the polarized light transmitted through the fiber 20 is converted into a parallel beam through a condenser lens 40 and made incident on an optical sensor head part 120. The light is split by a nonpolarization BS 42 into the reference light which travels straight forwardly and the measurement light which is changed in its course to a right-angled direction. This reference light passes through a lambda/4 plate 44 and condenser lens 46 is reflected by a mirror 48, and passes through a condenser lens 54, so that the light is fed back through the same optical path. Further, if the rest of the measurement light passing through the BS 50 is not split equally by a bisected photosensor 58, the difference is subtracted from a bias voltage and the result is applied to a laminate piezoelectric actuator 70.

Filed: 1983-09-22
Abstract: PURPOSE:To make steel with less electric power consumption and excellent production ratio without lowering yeidl rate of iron by quick melting of steel by arc melting associated with oxygen blowing, followed by SiC blowing. CONSTITUTION:Scrap and other raw materials for steel making is allowed to melt quickly by simultaneous oxygen blowing is conducted upon refining of steel in arc furnace. Blowing of carbon powder, subsequently, is started while successive blowing of oxygen being made, and the arc is enveloped by bubbling of molten slags caused by reducing reaction of FeO in the molten slags resulted from the oxygen blowing, and the resultant development of CO gas for increasing thermal efficiency of arc heating.

Title: Digital signal recording device
Inventor: SASAYA TOMOHIKO
IPC: G11B5/09
Filed: 1988-07-14
Abstract: PURPOSE:To record plural kinds of digital signals having different bit rates without complicating the processing of signal by switching the rotation period of a rotary head according to the kind of input data having different bit rate from each other. CONSTITUTION:The division ratio of a frequency divider 8 corresponds to the number of bits of the input data which is recorded during one rotation of a rotary cylinder 10. Namely, since the number of bits of the data inputted during one rotation of the rotary cylinder 10 gets same if the division ratio is made constant without depending on mode data, the processing of data in a memory 4 can be made quite same. When the bit rates of the input data A-C are pretty different, the rotating speeds of the rotary cylinder are pretty different in this method. In such a case, the division ratio is made to be switched according to the input data. Thus, the plural kinds of digital signals having different bit rates can be recorded without complicating the processing of signal.
