Title: Picture processing system using charge storage medium
Inventor: MATSUO MAKOTO
IPC: H04N1/21
Filed: 1988-05-26
Abstract: PURPOSE:To reduce the time for reading and recording of an original by adopting a charge storage medium for an external storage device of a computer storing a picture data. CONSTITUTION:A prescribed original is recorded on a charge storage medium 3, a read head 101 scans the surface of the charge storage medium 3 to read the potential, and the result is subject to A/D conversion and read in a computer 103. In this case, the volume of the picture data is huge and lots of sets of picture information are recorded on a magnetic disk 105 or a magnetic tape (MT) 106. Analog information is recorded on the charge storage medium 3 by the exposure of the surface and if the medium 3 is used in place of the MT, the time required for recording and readout from/to the MT is saved. Thus, the total time from the original reading till the exposure recording is reduced.

Title: Equal pressurizing construction of shaft seal
Inventor: SERA YOSHIO
IPC: F16J15/447
Filed: 1978-10-19
Abstract: PURPOSE: To reduce the axial length of a shaft seal, by providing an equal pressurizing groove of reduced axial width on an annular equal pressurizing passage block between and end wall and a shaft seal ring so that the depth of the groove extends in the radial direction of the block.  
     CONSTITUTION: A groove D is provided on a passage block 7 mounted on an end lid 2 by bolts 8. A drilled hole E extends from the groove D in the axial direction and coincides with a drilled hole of the end lid 2 so that these drilled holes communicate with each other. The groove D communicates with chambers a, b, c between fins through holes of a shaft seal ring 4. As a result, the axial length of a hole G of the end lid 2 does not need to be larger than the width S of the groove D, as against a conventional olique hole. Therefore, the axial length of a shaft seal and the length of a rotor between bearings are reduced.

Title: Two-color developing method
Inventor: KOYAMA HAJIME
IPC: G03G13/01
Filed: 1977-10-28
Abstract: PURPOSE: To perform two-color development processing simultaneously with one processing by development-processing the two-color latent images having been charged to opposite polarities by the use of the carrier having been friction charged to opposite polarities and two-color toners respectively corresponding thereto.

Title: Semiconductor device
Inventor: ONISHI TATSURO
IPC: H01L21/3205
Filed: 1987-05-26
Abstract: PURPOSE:To prevent power supplying and grounding lines from being broken by thermal expansion and to decrease the area of a semiconductor chip, by composing power supplying and grounding lines of two conductor layers, while isolating the power supplying and grounding lines from each other. CONSTITUTION:A power supplying line 12 of aluminium divided into two sublines is formed on an insulating film 14 on a semiconductor chip 11. An insulating film 15 is deposited thereon and an aluminium grounding line 13 divided into two sublines is formed on the insulating film 15. Though stress is generated by thermal expansion concentrically at the corners of the power supplying and grounding lines 12 and 13, such stress is decreased because the width of the aluminium lines is decreased. In this manner, the power supplying and grounding lines 12 and 13 can be prevented from being broken by thermal expansion, and the area of a chip 11 can be decreased.

Title: Sheet processing device and image forming device
Inventor: HONMOCHI HIROKI
IPC: B65H37/06
Filed: 1998-05-13
Abstract: PROBLEM TO BE SOLVED: To stably stack double folded sheets without enlarging an ejection tray by supporting a stacking means binding a plurality of sheets and discharging the bound sheets in the double folded form with the sheet folded side set lower than the opened side. SOLUTION: In a stacking tray 106, a part (projection part 106a) close to an ejection roller 104 is lifted above a stacking face 106b, and a bundle P of sheets are discharged so that its folded side is arranged on the stacking face 106b on the stacking tray 106 front edge side (ejecting direction downstream side) while its opened side is placed on the projection part 106a. In this way, the folded side is lowered below the opened side, so that a height difference between both sides can be reduced even when the folded side is swelled more greatly than the opened side. When the bundle P of sheets is thick, that is, when the folded side is greatly swelled especially, a sheet ejection speed by the ejection roller 104 is reduced so that the opened side of the bundle P of sheets is placed on the projection part 106a in the discharging process.  When the bundle P of sheet is thin, a sheet bundle ejection speed by the ejection roller 104 is increased, arid the bundle P of sheets is discharged onto the stacking face 106b with the opened side prevented from being placed on the projection part 106a.

Title: Flexible disk device
Inventor: KATOU SHIYOUNOSUKE
IPC: G11B17/03
Filed: 1984-06-25
Abstract: PURPOSE:To avoid locking a diskette at a wrong position by providing a lifter cam which allows a collet hub to be locked by a spindle and keeping the position control of the diskette until the collet hub is connected to a spindle. CONSTITUTION:A clamp lever 4 is attached rotatably to a lifter hub 6 and at the same time a lifter cam 3 is held rotatably to the hub 6 and allows a collet hub 1 to be connected to a spindle 2 when the lever 4 is actuated. Therefore the hub 1 is not connected quickly to the spindle 2 by the lever 4 owing to the presence of the cam 3. Thus the position of a diskette is controlled to the spindle 2 immediately before the hub 1 is connected to the spindle 2. Then the lever 4 is actuated to lock the diskette 5 to the spindle 2. This device prevents locking of the diskette 5 to the spindle 2 at a wrong position and then improves the quality of a flexible disk device.

Inventor: MATSUGAKI ISAO
IPC: H04N7/167
Filed: 1991-05-02
Abstract: PURPOSE:To provide a video scrambling circuit which can reduce a memory capacity and can use and constitute an easy control circuit. CONSTITUTION:A PN generating part 6 generates a random signal S5 of 1 bit for 1 horizontal scanning period of an analog video signal based on a PN initial value and a sample number counting counter 5 counts the number of the sample of 1 horizontal scanning period. A memory control part 7 discriminates the starting point and the termination of the effective screen from the output of the sample number counting counter 5 and controls the reading sequence of an image memory 4 based on the random signal S5. Since the scrambling processing and the de-scrambling processing can be performed by the same circuit, the necessary memory capacity can be reduced. Since it is not necessary to add the additional sample to the cut part of the effective screen as conventional, the video scrambling circuit can be constituted by using the easy control circuit.
