Title: Manufacture of zirconium oxide powder
Inventor: KIUCHI NORIHIRO
IPC: C01G25/02
Filed: 1983-11-04
Abstract: PURPOSE:To manufacture fine zirconium oxide powder having a narrow particle size distribution, high activity and favorable sinterability by treating zirconium hydroxide hydrate in vacuum to freeze it, raising the temp., and carrying out freezing again by treatment in vacuum and drying by the sublimation of ice. CONSTITUTION:An alkali soln. is added to zirconium oxychloride to form zirconium hydroxide, and this zirconium hydroxide is dried in vacuum. When filtration is carried out in a pretretment stage, porous porcelain is put on the bottom of a vacuum chamber, to remove water before and after drying, and the zirconium hydroxide is allowed to stand in vacuum. It is decomposed into H2O and ZrO2, H2O is vaporized, and cooling proceeds by the latent heat of vaporization, so freeze-drying is carried out. The freezed matter is allowed to stand at 10-25 deg.C so that it is held at about 0 deg.C, and an excess of water is removed. Treatment in vacuum is then carried out again, and ice is sublimed. The resulting dried powder has 0.05-0.003mum small particle size, 120-150m<2>/g large surface area, high activity and favorable sinterability. Conventional powder has 40-70m<2>/g surface area.

Title: Rotary magnetic head device
Inventor: KATO KENICHI
IPC: G11B5/53
Filed: 1988-08-19
Abstract: PURPOSE:To prevent a tape shape body from being damaged by performing the chamfering of an edge part so that the edge part corresponding to the rotating direction of a rotary drum on a sliding contact plane with the tape shape body of a video head is prevented from being protruded over the outer peripheral plane of the rotary drum. CONSTITUTION:The chamfering of the edge part P on the sliding contact plane 11a separated by an interval f3 in a direction corresponding to the direction of rotation thetaof the rotary drum from a gap forming plane 11d is performed on the video head 11 with an angle beta along a straight line 11b. When the video head 11 is mounted on the rotary drum 1 via a mounting base, the quantity h3 of protrusion of the head 11 over the outer peripheral plane 1a of the rotary drum 1 is set at around 27mum. Therefore, spacing loss between a magnetic tape being brought into contact slidably with the slidable contact plane 11a of the head 11 can be suppressed at minimum. In such a case, the edge part S in the head 11 of the magnetic tape with the slidable contact plane 11a corresponding to the direction theta is positioned at a side inner than the outer peripheral plane 1a of the rotary drum 1, therefore, the head output of the head 11 can be improved remarkably, and the spacing loss can be maintained at minimum, and the edge part of the tape can be prevented from being rolled in the edge part S of the head 11.

Abstract: PURPOSE:To perform automatic speedy focusing operation with high percision by detecting the deviation of an actual subject image formation surface from a prescribed image formation surface and then generating an image plane movement extent signal and a focal length signal, and controlling the extent of driving of a focusing lens. CONSTITUTION:Generating means 27, 28, and 29 for image plane movement extent signals convert the driving extent of a focusing lens L1 into an image plane movement extent signal showing the extent of movement of an image plane accompanying the driving in prescribed relation irrelevant to variation in focal length, and generating means 36 and 37 for focal length signals generate the focal length signal relating to the set focal length of an influencing lens with variable focal length to control the driving extent of the focusing lens L1 on the basis of the image plane movement extent signal and the image plane shift signal of a focuse detector 6. Consequently, even when the focal length is varied, the focusing lens L1 is driven to move the image plane by the image plane shift detected by the focus detector 6 all the time.
