Title: Developer recovery method for developing device
Inventor: WAGI SUSUMU
IPC: G03G15/09
Filed: 1987-12-28
Abstract: PURPOSE:To easily and efficiently recover a developer by rotating a developing sleeve in the reverse direction at the time of recovering the developer. CONSTITUTION:An agitating paddle 9 is projected forward from a front plate 12 of a developing unit, and a developer outflow aperture part 13 is provided under the projecting part, and a recovery cover 14 is closed unless the developer is recovered, and the recovery cover 14 is opened at the time of recovering the developer. When the developer is recovered, a developing sleeve 4 is reversed and is set to the crest cutting state and the agitating paddle 9 is rotated and the recovery cover 14 is opened to drop the developer carried forward from back by an outside screw 6 from the aperture part 13, thereby recovering the developer. Consequently, the developer is not scattered out of the developing unit and even the developer whose recovery is conventionally difficult can be recovered even when the developer whose life expires is automatically recovered in a copying machine or the like. Thus, most of the developer is recovered and the recovery time is shortened.

The raw material crucible 5 and the recovering casting mold 6 are sealed double by a quartz outside cylinder and inside cylinder 4. A vacuum degree of 1×10<-2> Torr is maintained in the inside cylinder by an evacuation system 2. When the furnace tap. is kept at 600 deg.C, the magnesium in the raw material evaporates and condenses to the inside surface of the inside cylinder. The condensed magnesium falls in the form of grains into the recovering casting mold. These grains are recovered and >=6N magnesium is obtd.  The grains lower in vapor pressure than the magnesium remain in the raw material crucible but the grains of the higher vapor pressure are discharged in the form of gases and are sucked into a cooling trap 8. These gases are cooled by a cooling flange 7 and are solidified.

IPC: H03K4/02
Filed: 1989-12-20
Abstract: PURPOSE: To make quick phase-coherent frequency switching executable by providing a control logic circuit and a time measuring unit. CONSTITUTION: A time measuring unit ZME periodically outputs a time mark ZM to a control logic circuit SL. The circuit SL stops an increment process through a line ss when a time mark ZM3 arrives (count time tA) and a calculator R calculates count time tN (tN=tA+T), a future phase increment Δϕn , the value of the phase ϕA at the count time TA, and the value of the phase ϕN at the count time tN. The calculator R also calculates a phase difference Δϕ and adds or increments the phase difference Δϕ to the content of a phase register stage PR. After a prescribed delay time T has elapsed, the increment process is restarted at the count time tN matching a time mark ZM7 and a new frequency is generated in the initial phase ϕN. Therefore, quick phase-coherent frequency switching can be performed.

Title: Shading correcting method for picture input device
Inventor: NAKAJO HIDEKI
IPC: G06T1/00
Filed: 1989-12-21
Abstract: PURPOSE:To attain the shading correction with high accuracy by decreasing the number of picture elements of the shading data for acquisition of the mean value in an area where the difference of shading data is large between the picture elements in comparison with an area where the difference of shading data is small. CONSTITUTION:The reflected light sent from a picture reading surface 2 is turned into the signals via a CCD sensor 3 and sent to a RAM 5 and a multiplier 6 after A/D conversion 4. A CPU 7 discriminate an area where the difference of shading data is large between picture elements contiguous to each other from an area having a small difference of shading data based on the shading data obtained for each picture element in a production mode for shading correction value. In the area having a large difference of shading data, the mean value of data on the number of picture elements smaller than an area having a small difference of shading data. The obtained mans value is stored in an EEPROM 8 as the shading correction value common to both areas. In a normal picture reading mode, the CPU 7 reads the shading correction value out of the PROM 8 and sends it to the multiplier 6 via the RAM 5. Then the picture signals undergone the shading correction are outputted to a processor.

Title: Method of stopping plasma etching of insulation film at base conductor
Inventor: MIYATA KOJI
IPC: H01L21/768
Filed: 1996-11-09
Abstract: PROBLEM TO BE SOLVED: To obtain an etching selectivity of an insulation film to a base being a conductor by etching the film with a plasma. SOLUTION: The plasma etching pulls positive ions to a substrate surface by applying a high frequency bias to the substrate. Running of the etching always needs ions entrance into the substrate. Adding a positive d-c bias component to the conventional high frequency bias suppresses the base from being etched. As the insulation frequency surface is charged negative owing to the high frequency bias, positive ions enter. On the base conductor surface, the positive ions are repelled by the effect of the positive d-c bias. In application e.g. to a contact hold forming step, after forming the contact holes, no positive ion enters the base to result in suppression of the etching. This solves the problems in the conventional method using a carbon fluoride plasma, such as poor selectivity, unstable process, influence on environment, etc.
