Title: Developing device
Inventor: TANAKA TOYOKI
IPC: G03G15/09
Filed: 1981-12-01
Abstract: PURPOSE:To easily execute development even in case of a one component toner whose electric resistance is comparatively high, by providing a projecting part for taking large width contacting with the toner by making it oppose a photosensitive body, on the surface of a sleeve of a non-magnetic material. CONSTITUTION:On a sleeve 11, a projecting part 12 is provided so as to be opposed at a distance of an interval A to the surface of the photosensitive body in the longitudinal direction at a position opposed to a photosensitive drum 4. In this state, a toner 3 passes through the projecting part 12 and is carried to a developing area. Since the projecting part 12 of the sleeve 11 is formed as one body with the sleeve 11, contact width of the toner 3 and the photosensitive drum 4 is increased by the projecting part 12 and becomes like width D. As a result, a contact area of the toner 3 and the photosensitive drum 4 becomes large, and also a contact time is extended, therefore, the development is executed comparatively easily even if a conventional reservoir of the toner 3 is not provided.

Filed: 1988-08-03
Abstract: PURPOSE: To make a device compact and light-weight and to improve the image transmission rate by providing a half-reflection concave mirror or its holography analog and a cholestric liquid crystal element. CONSTITUTION: An optical collimation device 30 is provided with a half- reflection concave mirror or its holography analog 42 and a cholestric liquid crystal element 44 which is formed so as to reflect an RHCP(Right-Hand Circularly Polarization) image in a band B having the center at an approximately primary frequency (f). An external image 32 is transmitted to the half-reflection concave mirror 42 by a transmitter/combiner 40 and is transmitted to the cholestric liquid crystal element 44 by the half-reflection concave mirror 42. Thus, an excellent image transmission efficiency is obtained because the frequency in reflection transmission is low and the cholestric liquid crystal element 44 can transmit and/or reflect incident light in a high ratio.

Title: Position detecting device for moving body
Inventor: NUREDA KATSUHIKO
IPC: G01B21/00
Filed: 1984-09-19
Abstract: PURPOSE:To detect a position error by setting a speed pattern for moving a target position and judging whether the deviation between the contents of a counter and a logical position is within a permissible range or not at constant intervals of time. CONSTITUTION:Pulses generated by a pulse encoder 3 are inputted to a microcomputer 5 through the counter 4 to recognize the position of the moving body at the point of time. Then when an input part 8 supplies the target movement position of the moving body to a computer 5, the computer computes the speed pattern. The computer 5 stores logical positions at constant intervals of time when the moving body moves according to the pattern and also stores permissible errors at the logical positions. The computer 5 compares the current logical position with the contents of the counter 4 a specific time later to judge whether the deviation is within the permissible range or not. When not, the computer 5 outputs a stop instruction to a motor controller 6. Consequently, high-safety movement control is performed.

Title: Light fastness and weathering tester
Inventor: YURUGEN BUITSUTO
IPC: G01N17/00
Filed: 1988-08-05
Abstract: PURPOSE: To appropriately irradiate a test piece with radiation by providing a tubular radiation source and an infrared-ray absorbing surface passing through the axis of the source in a tubular filter which transmits ultraviolet rays and visible light, but reflects infrared rays. CONSTITUTION: A tubular cylindrical filter 1 surrounds a tubular radiation source 2 with the axis 4 of the filter 3 in parallel with that 3 of the source 2 and an infrared ray absorbing surface 5 is provided through the axes 3 and 4. A filter layer 6 which transmits ultraviolet rays and visible light, but reflects infrared rays, is formed on the internal surface of the filter l and infrared rays radiated from the source 2 are discharged as heat, because the rays are reflected by the layer 6 and absorbed by the surface 5. Since the source 2 is exccentrically arranged from the axis 4 of the filter 4, all infrared rays reflected by the internal surface of the filter 1 reach the surface 5. Therefore, a test piece can be irradiated with radiation by absorbing most of the infrared rays without reducing the infrared rays and visible light radiated to the outside.

Title: Magnetic artificial lattice film
Inventor: NAGAI YASUHIRO
IPC: H01F10/08
Filed: 1987-08-04
Abstract: PURPOSE:To make it possible to manufacture highly reliable magnetic components such as thin film heads with high yield by forming a periodic structure on a substrate, wherein an Fe layer and an Ni layer are alternately stacked and such stacking is repeated. CONSTITUTION:This is a magnetic artificial lattice film wherein an Ni layer 6 and an Fe layer 7 are alternately stacked. In an artificial lattice film formed by the Ni layer 6 and the Fe layer 7, the crystallinity of the Fe layer 7 is disrupted and transformed into an excellent soft magnetic properties, or magnetostrictive effects, which may change a magnetic domain structure at the time of processing a magnetic component and reproducing a magnetized signal, can be controlled by the thickness of either the Ni layer 6 or Fe layer 7 and the lattice period. The cycle of the stacking is preferably 50nm or less. The period which is more than 50nm causes the coercive force to be 4 oersted or more and therefore make it unsuitable for use as magnetic poles for magnetic heads. According to this constitution, a magnetic artificial lattice film with high Bs (high saturation magnetic flux density), thermal stability, oxidation resistance, and good soft magnetic properties, can be obtained.

Title: Manufacture of metal thin film magnetic recording medium
Inventor: HOSAKA TOMIJI
IPC: G11B5/66
Filed: 1992-07-22
Abstract: PURPOSE:To check the generation of damage and rust by a method wherein the surface of a magnetic layer undergoes a burnishing with a polishing tape using abrasive grains with an average particle diameter of below 0.5mum and the surface of a protective film layer provided thereon does so with a buffing polishing member. CONSTITUTION:A magnetic layer 10 is formed on a non-magnetic support 9 and then, the surface thereof undergoes a burnishing with a polishing tape with an average particle diameter of below 0.5mum using Cr2O3 and Fe2O3 as grinding substance for a polished layer. As the particle diameter of the abrasive grains reduces, the polishing power decreases a little. But when a protrusion exists on the surface of the tape, a contact pressure of the part with the polishing tape becomes higher than other parts, which allows the protruding part to be polished in preference and hence, the height of the protrusion can be lowered to an such an extent as not to affect a drop out DC. After the burnishing, a diamond-like carbon protective film layer 11 is formed and the surface thereof is subjected to a burnishing with an unwoven cloth. Thus, matters adhering to the layer 11 can be removed without damaging the layer 11. Thereafter, a lubrication layer 12 is formed on the layer 11.

Abstract: PURPOSE: To shorten a time required for rough grinding work by speeding up the rotating speed of a work when the rough grinding work is applied and to eliminate an adverse effect on working accuracy. CONSTITUTION: The work Wa is ground in nonreal circular shape in accordance with lift data by moving a grinding wheel base 8 based on profile data found corresponding to the lift data representing the finishing shape of the work Wa and a grinding wheel diameter as rotating the work Wa. Smoothing by a prescribed filter degree is applied to the work Wa by a filter circuit 22 so that acceleration in the movement of the grinding wheel base 8 when the work Wa is rotated at the same speed can be reduced. The rough grinding work is applied to the work Wa based on the profile data after smoothing, and also, after that, finishing grinding work is applied to the work Wa based on original profile data. When the rough grinding work is applied, main axis rotating speed is increased by the share that the acceleration of the grinding wheel base 8 is reduced.
