Title: Production of magnetic iron powder
Inventor: ISHIBASHI TOSHINORI
IPC: B22F9/22
Filed: 1981-09-08
Abstract: PURPOSE:To obtain magnetic iron powder for magnetic recording materials having excellent dispersibility, orientability and magnetic characteristics by adding Ca ions to an aq. suspension of goethite deposited with water glass and subjecting the suspension to filtering, heating and reducing. CONSTITUTION:Water glass is added to an aq. suspension of goethite (needle hydrated ferric oxide) under agitation to deposit the water glass on the goethite. Nitric acid, etc. are added to the soln. to control pH to about 6-8. Ca ions of an aq. calcium chloride, etc. are added under agitation to allow the slurry to flocculate. The flocculated slurry is filtered and the resultant cake is rinsed and dried. After the dried cake is calcined and reduced, oxidized films are formed on the surfaces of the reduced iron powder, whereby magnetic iron powder is obtained. In this method, Na ions in the water glass are substituted with Ca ions by the addition of the Ca salt, whereby the residual content of Na is reduced.  Filtering and rinsing are made easy by the coagulation of the slurry.

CONSTITUTION:The titled device is provided with the 1st pulling-out post 61 which pulls out a magnetic tape 37 from the opening at the winding side of a cassette 34 and, at the same time, moves the tape 37 in the direction of height, a tape guides installed to a rotating ring 50 including posts 56 and 57 respectively inclined to the directions shown by th arrows (h) and (i), and the 2nd pulling-out post 51 which pulls out the tape 34 with a little time lag after the post 61 does. When the tape 37 is pulled out, the tape 37 is pulled out from a feeding side reel 35 and, at the same time, the tape height is moved by means of the 1st pulling-out post 61 so that the tape height at points where the tape 37 is contacted with or separated from posts 54 and 55 implanted in the turning ring 50 can be made coincident with the height of each post. Therefore, the tape loading device of a VTR having a large winding angle can be constituted with the small-aperture turning ring 50 and the device can be reduced in size and weight. Moreover, occurrence of tape damage can be reduced, because the tape height completely coincides with post heights when the tape is contacted with or separated from the posts.

Title: Method and circuit device for recoverying bit clock form received digital communication signal
Inventor: DEIITAA PAUAA
IPC: H03L7/099
Filed: 1989-06-02
Abstract: PURPOSE: To restore a bit clock even though a pulse that has a different period is received by sending a phase correction signal to a counter independently of the period of a receiving pulse only when the pulse edge of a bit clock that is supplied by a counter does not exist in the center of the receiving pulse. CONSTITUTION: A phase evaluation logic circuit PAL decides the count at which the leading and trailing edges of each receiving pulse of a communication signal are generated from the combination of three outputs A, B and C of a counter Z and two outputs Q1 and Q2 of a shift register SR. In such cases, the circuit PAL sends a correction signal to the counter Z through the 1st or 2nd control line SLU and SLD, only when the pulse edge of a local bit clock is not positioned in the center of the receiving pulse of a communication signal independently of the period of a receiving pulse. Thereby, real phase shift can be discriminated from just a momentary edge drift for a pulse period that is shorter or longer than a desired period.

Title: Measuring method for pattern area rate
Inventor: MASUDA TOSHIAKI
IPC: G01B11/28
Filed: 1986-06-17
Abstract: PURPOSE:To improve the effect of ink presetting on printed matter where a pattern is extremely small by correcting differently the area rate of patterns measured on a 'SUMI' (Japanese ink) plate and other color plates. CONSTITUTION:A laser beam from a light source 3 is scanned by a scanner 4 on the 'SUMI' plate 1 and its reflected light is converted by a photoelectric converting element 6 into an electric signal, which is A/D-converted 7 and inputted to a CPU 8 to calculate the pattern area rate of each beam spot 5. When the 'SUMI' board 1 is the 'SUMI' plate, the pattern area rates of respective spots 5 are totalized to calculate the pattern area ratio of each ink zone 2. When this rate is about <=10%, the corrected pattern area rate of the zone 2 is set forcibly to 10%. Then when the pattern area rate of each spot is about <=10% as to a color plate, the corrected pattern area rate of each spot is set to 0%. When not, the value obtained by multiplying the measured value by about 120% is employed as the corrected pattern area rate. Thus, 'SUMI' characters are printed sharply and sufficient is supplied to a pattern part, thereby obtaining a print of good quality.
