Title: Bit image data compressing method
Inventor: NISHIKAWA HIDETO
IPC: H04N1/415
Filed: 1989-01-30
Abstract: PURPOSE:To efficiently compress the bit image data displayed in halftone by performing the encoding of a block having the same information encoded on neighboring two matrices after attaching the information representing the number of repeat of the block on a first block in the case of repeating the above block. CONSTITUTION:A scanner 1 compresses data with an MR system in the case of being set at a binarization processing, and outputs compressed data to a CPU 4. Meanwhile, when it is set at a halftone processing, the bit image data is divided into matrices of (4X4) bits, and the data in which the (4X4) bits are compressed to four bits is outputted to the CPU 4. At such a case, the number of bits in the matrix is encoded, and the same information encoded on the neighboring two matrices is encoded as one block, and also, in the case of repeating the black having the same encoded information, the information representing the number of repeat of the block is attached on the first block, then, encoding is performed. In such a manner, it is possible to efficiently compress the bit image data displayed in the halftone.

Title: Joining method for martensitic stainless steel
Inventor: HIYAMIZU TAKAO
IPC: B23K20/02
Filed: 1998-01-16
Abstract: PROBLEM TO BE SOLVED: To provide a joining method for a martensitic stainless steel which is excellent in joining strength and toughness, moreover whose working time is short. SOLUTION: Between the martensitic stainless steels, an insert material consisting of Ni-based alloy foil 20 μm to 100 μm in thickness and whose melting point is 1250 deg.C or below, is inverted. Under the conditions of 1290 deg.C-1400 deg.C joining temperature, 3 Mpa-9 MPa pressuring force and 30 sec-180 sec holding time, joining is performed under a nonoxidation atmosphere. After cooling the joined part almost to the room temperature, it is reheard to from 600 deg.C to a temperature below the A1 transformation point of a material to be joined. For the surface roughness Rmax of a joined boundary, 50 μm or below is preferable, and for heating, high-frequency induction heating or high-frequency direct energizing heating applies to.

Title: Control of automatic circulation document carrier
Inventor: NONAKA MITSUHIRO
IPC: G03B27/62
Filed: 1989-01-30
Abstract: PURPOSE:To prevent giving damage to a document by performing ejection of a sheet in a semi-automatic carrier mode preceding the starting of an automatic circulation carrier mode. CONSTITUTION:When a document deposited on a document tray 4 is to be copied choosing an automatic circulation carrier mode, preceding the starting of the actuation, ejection in a semi-automatic carrier mode is carried out. That is, in supplying the document, a forked claw solenoid is turned 'ON', so as to switch a forked claw 36 on a continuous line, while a carrier motor and an ejection motor are turned 'ON' so as to drive a carrier belt 12 and an ejection roller 23. The process is normally wound up in no-load running, however, if there is a paper sheet left behind on a contact glass 2, the document is directly carried to a document discharge port 34, and is directly discharged onto a paper discharge tray 35 from the document discharge port 34. Even if the document is thick, it is hard to give damage thereto due to linear carrier ejection. After the process, actuation is started in the automatic circulation carrier mode.

Title: Cathode-ray tube
Inventor: IWASAKI YASUO
IPC: H01J29/20
Filed: 1981-02-12
Abstract: PURPOSE:To increase the image contrast of a fluorescent screen by using as a front-side glass plate attached to a cathode-ray tube, a plate glass containing neodymium oxide. CONSTITUTION:When a belt-like emission spectral green G color phosphor is applied to a cathode-ray tube to which a front-side glass plate made of neodymium glass is attached, the peak wavelength of the energy strength of the emission of the above phosphor is preferred to be located between 545nm, at which the luminance of the emission is maximized, and 530nm, at which the color reproducing range of the emission is maximized. If the above peak wavelength is located ouside this range, one of the luminance characteristic and the color reproducing characteristic is deteriorated to a large extent. Thus, a fluorescent surface with an enough luminance and a sufficient chromaticity can be obtained by using a relatively cheap belt-like emission spectral green G color phosphor without using a rare-earth-group green G color phosphor, which is expensive and has some problem in its luminance characteristic.
