Title: Magnetic head
Inventor: KUDO ICHIRO
IPC: G11B5/187
Filed: 1989-06-27
Abstract: PURPOSE:To increase a linear recording density even if a high magnetic permea bility material is not used by setting a writing head in such a manner that the longitudinal direction of a head gap is in the transverse direction of tracks and forming the shape of the tape sliding surface to the shape having the curved surface smooth to the tape. CONSTITUTION:A ferromagnetic substrate 2 is worked to constitute a closed magnetic circuit and a coil 1 is wound around a part thereof to generate a writing magnetic field. The magnetic gap 3 for leaking the writing magnetic field is formed near a tape sliding surface 11 by using a nonmagnetic material. A magnetic tape 4 which is a medium slides in the tape traveling direction of an arrow dt with respect to the magnetic head. The sliding surface 11 is worked to the shape having a suitable curve in the tape sliding direction dt for this purpose. The longitudinal direction of the magnetic gap 3 constituted of the magnetic head and the magnetic yoke of the yoke type head for reproduc tion is set in the track direction in such manner, by which the high-density magnetic recording and reproducing at the relatively large gap length are ena bled even with the head material having a low saturation magnetic flux density and a low coercive force medium material.

Title: Optical arithmetic element
Inventor: MIFUNE HIROYASU
IPC: G02B27/46
Filed: 1988-07-01
Abstract: PURPOSE:To optically execute all processings by executing an optical information processing in a Fourier-transformation optical system by using a non-linear element having an electro-optical effect and a threshold characteristic and a filter together with a deflector and an analyzer. CONSTITUTION:A deflector 3, a non-linear element 5 provided with a filter 4, a half mirror 6 and an analyzer 7 are provided in order between lenses 1, 2. In this state, a Fourier spectrum of total projection data is written in the non-linear element 5 having an electro-optical effect and a threshold characteristic to an exposure value. When a light source of a linearly polarized light is used, readout is modulated by the electro-optical effect of the non-linear element 5, and a light beam reflected from this non-linear element 5 becomes an elliptically polarized light. Since the non-linear element 5 is provided with a half mirror 6 for allowing a write light to transmit through and for reflecting a read-out light, the elliptically polarized light which has been obtained transmits through the analyzer 7, and by bringing this light to two-dimensional Fourier- transformation by a reverse Fourier-transformation lens 2, a reproducing image is obtained. In such a way, all processings can be executed optically.

An air compressor 32 with a temp. elevation regulating mechanism 31 is actuated to suck and compress the air contg. the microorganisms and to heat the air to 30 to 40 deg.C. This air is discharged and is ejected from the air ejection holes of an air feed pipe part 34 so as to be blown out of the bottom of a housing tank 21 via an air bent and water permeating bed layer 36. The excess moisture in the controlled waste 10 evaporates or flows down by gravity. The moisture is replenished by lading up the eliminated liquid and spraying this liquid from a spraying section 62 in case of deficiency of the moisture. The waste is thus maintained in the state of easily activating the fermentation state, by which the fermentation period is shortened and the compost is obtd. with good efficiency.
