Title: Absolute type encoder
Inventor: MURAKAMI TAKU
IPC: G01D5/18
Filed: 1988-04-28
Abstract: PURPOSE:To obtain an inexpensive encoder which can measure an absolute position by constituting it so that the number of chevron shape patterns of a magnetic flux is varied by the relative movement of a magnetic material and the magnetic flux detector. CONSTITUTION:The title encoder is constituted of a magnetic material 2, and a magnetic flux detector 1 consisting of a magneto-resistance element in which a pattern (shown in the figure) by a combination based on a chevron shape pattern is formed in the same direction as one side of the magnetized surface 3 of this magnetic material 2. When the detector 1 is moved by no-contact at a prescribed interval on the magnetic material 2, the magnetic flux quantity emitted from the magnetic material 2 is varied by following up its pattern 3, and the number of chevron shape patterns of the detector 1 on which both are overlapped is varied. The detector 1 consists of a resistance element whose resistance value is varied by a variation of a magnetic flux, therefore, when the number of chevron shape patterns is varied, its resistance values (6 and 7 in the figure) are varied. Accordingly, by detecting such variation as a voltage or a current, a relative position of the detector 1 and the magnetic material 2 can be detected with high accuracy and surely.

Abstract: PURPOSE:To prevent the generation of contamination and damage on the surface of a substrate by a method wherein, when an insulation isolation region is going to be formed, the surface of an Si substrate is prevented from exposure when an anisotropic etching is performed for formation of the mask of framed nitride film. CONSTITUTION:An SiO2 film 2, to be used for a pad, is formed on an Si substrate 1, the first nitride film 3 is formed thereon by performing a CVD method, and a patterning operation is conducted using a lithographic technigue. Then, an Al film 4 is formed by sputtering under the state wherein a poor covering property is present, and a cut 5 is formed in the vicinity of the lower end of the stepped part of the nitride film 3. After a groove 6 has been formed by removing the SiO2 film located below the cut 5 by etching, the Al film is removed, and the second nitrogen film 7 is formed. All the nitride films, excluding the nitride film 3 and a frame (sidewall) 7a, are removed by performing anisotropic etching. As a framed nitride film mask is formed in the state wherein the oxide film 2 is left on the substrate 1, the generation of contamination and damage on the surface of the substrate 1 can be prevented. Therefore, the field oxide film to be used for insulation isolation is formed by performing the ordinary method using the nitride film as a mask.

Abstract: PURPOSE:To confirm the recording content with stable synchronization by means of a monitor or the like by adding a reference synchronizing signal of a servo to a reproduced Y signal and outputting the resulting signal at reproduction of each track for unrecorded signal except a video signal, an audio signal and a data signal or the like. CONSTITUTION:A microcomputer 13 outputs a VABS signal at reproduction of tracks other than video tracks based on a level of an ID data and an RF envelope obtained by reproducing a recording medium 2. That is, when each track of unrecording signal except a video signal, audio and data signal of the medium 2 is reproduced, no PBSSYNC signal exists, the VABS signal is set, an REFSYNC is selected as a SWSYNC and the REFSYNC is added to a reproduced Y signal and the resulting signal is outputted. Thus, the recording content is confirmed with stable synchronization by a monitor or the like from a reproduced output signal and since the PBSSYNC and the REFSYNC are almost coincident in a range when the vertical synchronization is within jitter of servo, when a track other than a video signal and a video track are switched with each other, shock of the monitor is hardly caused.

Abstract: PURPOSE:To obtain a picture of little blurring in case of picking up its image in a short charge storage time by constituting a system of automatically displaying one frame picture with one field image signals alone. CONSTITUTION:When an image pickup switch 52 is turned on after changing over to a special pickup mode, a quantity of light for illumination increases according to an output from a light quantity control signal generator 73, and an output from a CDS circuit 25 decreases to almost 1/10 and then increases accompanied by an increase of outgoing light quantity corresponding to a withdrawal of dimmer member 14 afterward. An output from a detector 41 also decreases to almost 1/10, but it increases in accordance with the increase of the light quantity and is put into a memory controller 54 through a comparator 75. At that time, write enable pulses are applied to field memories 59a, 59b in a frame memory 28 from the memory controller 54 by an applied signal from a mode control circuit 53. Image signals in both fields for the next one frame are memorized in the field memories 59a, 59b respectively, a read inhibit pulse is further applied to 59b from the memory controller 54 so as to inhibit reading out, and the image signals memorized in one field 59a alone are put out as a frozen picture.
