Patent JP-H0847748-A (JP)
Title: Mold for continuous casting
Inventor: SHIRAI YOSHIHISA
IPC: C23C4/18
Filed: 1994-08-08
Abstract: PURPOSE:To stably provide slab with excellent surface by forming the sprayed coating made of hard metal, cermet or ceramics which is sealing treated with the refractory material on the molten metal. CONSTITUTION:Because pores and cracks present on the surface of the sprayed layer are covered with the sealing agent, the atmospheric gas is prevented from being thermally expanded and inflated out of the surface of a mold even when the sprayed layer is brought into contact with the molten metal and reaches the high temperature, and the solidification delay of the molten metal is not generated in the part where pores or cracks are present, and the slab with excellent surface condition is obtained. In addition, even if the sealing is executed on the sprayed layer, only a part of pores or cracks on the surface are covered by the sealing material, and the reduction of the heat reduction speed of the mold and the improvement of the wear resistance which are the original purpose of the sprayed layer are not damaged. The slab with excellent surface condition is obtained while the defects such as cracks, recesses or porosities of the slab are prevented by uniformly forming the solidified shell through the reduced heat removal speed of the mold.

IPC: C01G49/08
Filed: 1991-08-16
Abstract: PURPOSE:To produce a polyhedral magnetite granular powder of specified shape having a narrow particle size distribution and excellent in dispersibility. CONSTITUTION:The average particle diameter of this polyhedral magnetite granular powder is controlled to 0.1-1.5mum, the number of faces on the surface to almost 10 and the specific surface to 3-40m<2>g. An aq. ferrous salt soln. is mixed with an aq. soln. contg. alkali metal hydroxide and carbonate to obtain a slurry, and an oxygen-contg. gas is blown into the slurry which is oxidized to produce the powder. In this case, the molar ratio of the ferrous salt to alkali metal hydroxide and carbonate is controlled to 1:0.4-1.2:0.8-1.6, and the oxidation reaction is conducted at 75-100 deg.C.

Title: Moving handrail of passenger conveyer
Inventor: HARUTA YASUMASA
IPC: B66B23/24
Filed: 1989-08-09
Abstract: PURPOSE:To strengthen the restoring force of a sectional form and to prevent loss of flexibility by burying a reinforcing core material for a moving handrail in the whole of the cross section of the handrail or along both sides thereof, and intermittently disposing the same at spaces in the longitudinal direction of the handrail. CONSTITUTION:A reinforcing core material 5 is constructed by a steel plate formed to be C-shaped in its cross section. The core material is buried in a rubber layer 2 along the substantial whole including both approximately semi-circular side portions of the C-shaped cross section of the moving handrail 1. A lot of core materials are intermittently disposed at fixed spaces in the longitudinal direction of the moving handrail 1. As reinforcing material, hard plastics or rubber is used in addition to a steel plate. The restoring force of the cross sectional form of both side portions of the moving handrail can be strengthened, and furthermore, as the core material is hard to deform permanently, even if the handrail is used for a long time, the opening width of the handrail will not be expanded, and the grasping power to the handrail guide will not be lowered due to unfolding of a lug portion. Furthermore, the loss of flexibility of the moving handrail can be prevented by the intermittent arrangement of the core materials.

Filed: 1990-08-02
Abstract: PURPOSE:To surely allow a developer to pass a through-hole by pressing the developer on a porous thin plate by a developer pressing member and simultaneously, forming an electric field between a thin plate and a developer carrier. CONSTITUTION:In this developing device 10, the developer housed in a housing 13 is pressed toward a mesh member 14 by the developer pressing member 15. On the other hand, a bias voltage is applied between the member 14 and a developing roller 11, the developer passes the member 14 and enters a gap between the periphery of the roller 11 and the member 14. The outer periphery of an urethane rubber 11b on the developing roller 11 has surface roughness about 2 - 20mum, so that the developer is carried while sliding on the mesh member 14. Since the mesh member 14 is brought into pressurized contact on the periphery of the developing roller 11 over its proper length in a circumferential direction, the developer is surely triboelectrified by sliding on the member 14, an uniform thin layer is formed on the periphery of the roller 11, and carried to a region abutted on a photosensitive drum 20.

Title: Matching system
Inventor: ISHIGAMI MASAYUKI
IPC: G06K9/68
Filed: 1988-08-20
Abstract: PURPOSE:To execute matching processing at a high speed by reading a character code either simultaneously or in parallel with either the reading of the standard feature pattern of a recognition dictionary or a distance operation. CONSTITUTION:A control part 12 controls an address generating part 2, outputs the feature pattern of a recognition object character from a memory 1, controls address generating parts 6 and 7, and successively outputs the character code corresponding to the standard feature pattern from memories 4 and 5. Further, a distance operation part 8 performs an operation for obtaining the distance between the feature pattern of the recognition object character outputted from the memory 1 and the standard feature pattern successively outputted from the memory 4. The character code in the recognition dictionary is read while the standard feature pattern is read (or while the distance operation is executed) in the above-mentioned manner, and matching processing time can be shortened for time approximately the same as character code reading time.

Title: Image forming device
Inventor: TAMIYA TAKAHIRO
IPC: G03G15/01
Filed: 1995-07-19
Abstract: PROBLEM TO BE SOLVED: To attain a formed image of high quality by providing an optical sensor immediately in front of or behind a place where a photoreceptor belt is wound on a supporting roller energized with a spring and executing an excellent detection with the sensor and further, control corresponding to the output of the sensor. SOLUTION: A focal position P1 on the photoreceptor belt by the optical sensor 55 is set in a position nearer to one belt supporting roller than a position where a tension roller shaft center Omin when a tension roller 3 is displaced most to the side of one belt supporting roller by the vibration of the spring is projected on the photoreceptor belt by a parallel projection line perpendicular to a vibrating direction. Thus, even if the tension roller 3 is displaced by the vibration of the spring, in the focal position, the distance between the optical sensor and the photoreceptor belt is never fluctuated and an angle of reflection is never wandering, in a state where the surface of the photoreceptor belt is roughly parallel with the vibrating direction of the spring.

Filed: 1994-08-31
Abstract: PURPOSE: To prevent vibration and noise when an elastic member contracts by allowing a vibration preventing member to contact with the elastic member, so as to prevent the vibration generated by means of the elastic member, from just before its contracting operation is completed. CONSTITUTION: The coil part of a coil spring 11 comes into contact with a vibration preventing part 1c'' in the head of a fixed shaft 1c from before a lever 10 collides with a stopper 1h and when the lever 10 collides with the stopper 1h, the vibration preventing part 1c in the head of the fixed shaft 1c slightly deforms the coil part of the coil spring 11, to prevent the vibration of the coil spring 11 and absorb the chatter of a spring. Moreover, the coil part, of the coil spring 11 is started to contact with the vibration preventing part 1c from a little before the lever 10 collides with the stopper 1h, so that even if the lever 10 bounds at the time of colliding, the contact of the coil part with the vibration preventing part 1c' is never released. Thus, the vibration of the coil spring 11 is surely prevented and the chatter of the spring can be prevented as well.
