Abstract: PROBLEM TO BE SOLVED: To provide a powder developer spraying image forming apparatus having means for recovering developer stripped off from a developing roller during cleaning. SOLUTION: In a powder developer spraying image forming apparatus where a spacer 64 touching a developer roller 26 is arranged on the developer roller side surface of a barrier wall 46 in order to keep a constant distance between a through hole 54 in the barrier wall 46 and the developer roller 26, when the barrier wall 46 is vibrated for the purpose of cleaning, the vibration is transmitted through the spacer 64 to the developer roller 26. Consequently, a part of a developer 18 carried on the developer roller 26 is possibly stripped therefrom. A conductive member 70 is disposed while facing the developer carrying face of the developer roller 26 at least partially in order to generate a field for urging the developer 18' from the conductive member 70 toward the developer roller 26 during nonprinting time.

Title: Method and equipment for processing image signal
Inventor: MORRIS OCTAVIUS JOHN
IPC: H04N7/26
Filed: 1990-03-20
Abstract: PURPOSE: To detect an outline and an edge part in different styles by sectioning a luminance signal into an edge part and a closed area, determining their mean value, generating and, comparing their difference signal with a difference signal of an image signal that is similarly determined. CONSTITUTION: A luminance signal Y is inputted from a terminal 1 to a section device 2 and chromaticity signals U and V are inputted from terminals 2 and 3 to the device 2 through up-sampling converters 5 and 6 and LPFs 7 and 8. A signal Y which is sectioned into an edge part and a closed area and the up-sampled signals U and V are inputted to a modal filter 9 to trace a border of the signal Y and select a part of it and an adaptive outline smoothing circuit 10 determines the mean values of the area signals either side on the border or on a small area to generate the difference between the mean values. Similarly the difference of the image signal is generated and the differences of the both are compared to determine whether or not the border is a real edged part.  The signals Y, U, and V from the circuit 10 are subtracted from the source signal 12 to 14 and encoded to 17, 18, and 19 to obtain a Y luminance constitution signal and a U and a V chrominance constitution signal.

Abstract: PURPOSE:To cheaply manufacture on optical fiber suitable for use in a long wavelength region by feeding a halogen-contg. gas between a glass rod and a pipelike glass body prior to heat uniting them to prevent OH groups from mixing into the interface and lower the OH group content. CONSTITUTION:Valves 14, 17 are opened, valves 15, 16 are closed, and O2 is fed into liq. reservoir 9 to generate vapor of halogen-contg. compound 10. The vapor is introduced into support quartz tube 3 through valve 14, duct 11 and connector 6 together with O2, and it is led to exhaust gas treating unit 19 through the gap between low OH quartz tube 1 and dopant-contg. quartz glass rod 2, support quartz tube 4, etc. At the same time, tube 1 and rod 2 are vertically moved in ringlike heater 20 while being heated with heater 20. As a result, OH groups, H2O molecules, etc. present on the inner wall of tube 1 and the surface of rod 2 are removed by the dehydration action of compound 10. Tube 1 is then evacuated to about 0.3 atm, and by heating 20 tube 1 to about 1,600 deg.C from the lower end, tube 1 and rod 2 are fusion-bonded to obtain a fiber base material.

Filed: 1982-04-26
Abstract: PURPOSE:To secure transmitted data of high quality without decreasing an operation rate by connecting a master station and plural slave stations in a loop, and providing each station with a controller and a dual communication control part for processing. CONSTITUTION:The master station and plural slave stations 2 are connected in a loop by transmission lines 3 and the master station 1 is provided with a controller CT4 and a dual communication control part 6 to monitor and control plant processes. Each slave station 2 is provided with a CT5 for monitoring and controlling a specific part of plant processes and a dual communication control part 7 for transmitting and receiving signals to and from the control part 6. One of the transmission line 3 is laid for clockwise transmission and the other is for counterclockwise transmission. Data transmission is performed by dual operation normally and the communication control part of each station confirms the coincidence of check bits to output data to the transmission lines 3. If one side of the dual control part becomes faulty, the operation is carried on by only the other system and when both systems of some slave station are broken down, slave stations before and after the slave station return data to continue the operation while the faulty station is disconnected, evading a decrease in operation rate.

Title: Magneto-optical disk and magneto-optical recording method using the same
Inventor: MIZUNO MASAAKI
IPC: G11B11/105
Filed: 1994-04-06
Abstract: PURPOSE:To prevent damage and wear by a magnetic head by composing the sliding protective film of a magneto-optical disk which executes recording while sliding the magnetic head of a mixture composed of a UV curing resin and a lubricity imparting agent. CONSTITUTION:A magnetic thin film having perpendicular magnetic anisotropy is used as a magneto-optical recording layer. For example, amorphous alloy thin films of rare-earth transition metals, such as DyFeCo, TbFeCo, GdFeCo and NaFeCo, and artificial laminated films of noble metals/transition metals such as Pt/Co are used. Dielectric layers consisting of oxides and nitrides, such as SiO2, Al2O3, Ta2O3 and Si3N4, and mixtures composed thereof, and composite compds. such as Al-Ta-0 are usually preferably formed above and below the magneto-optical recording layer. In such a case, the recording is executed while the magnetic head is slid relative to the disk surface and, therefore, the durability and lubricity are assured by providing the surface of the magneto-optical recording layer with the sliding protective film directly or via the dielectric layer and reflection layer.
