Title: Facsimile signal processing system
Inventor: MIYAHARA YOSHIRO
IPC: H04N1/419
Filed: 1986-05-08
Abstract: PURPOSE:To improve repeatability with respect to a scan line error caused by noise on a line by replacing information on a scan line, which becomes a pair if a scan line including errors is detected at the time of decoding and processing runlength, with information delayed by one picture element. CONSTITUTION:If and input picture is scanned in a fixed direction and showned with a black picture element 1 and a white picture element 2, it attains a state as (A) shows. If picture elements included in the picture information composed of two scan lines, as (A) shows, is replaced at every two picture elements is (B) shows, said information attains a state as (C) shows. The scan lines 5 and 6 are runlength-encoded, a line synchronizing signal is added to the two lines, thereby forming a picture signal. A transmission side does the process, whereas the reception side does the process reversely. Then an original picture is restored. Thus even if line noise destructs information, scan line information becoming a pair is replaced with information delayed by one picture element. Therefore repeatablilty against noise can be improved.

Title: Ultraviolet-ray emitting device for wire rod
Inventor: KANEDA SHIGEYOSHI
IPC: G02B6/44
Filed: 1986-05-09
Abstract: PURPOSE:To obtain a high yield and a high productivity, and also, to cope with a variation of an emitting condition caused by a kind and a size of a wire rod, by executing hardening/drying of a covered ultraviolet-ray hardenable resin (UV resin) being stable extending from a low speed to a high speed. CONSTITUTION:Attention must be paid to a temperature rise of a wire rod caused by a radiation, because an ultraviolet-ray lamp 62 emits a light beam of wavelength of an infrared area, as well. Accordingly, as for a material of a moving shutter 11, it is appropriate to use a heat-resisting material for making no ultraviolet rays pass through, such as ceramics, an opaque quartz pipe or an Al vapor-deposited quartz pipe, etc. The moving shutter 11 is positioned at a leading-out port side of the wire rod, and the wire rod is placed so as to run in order of a leading-in port of the wire rod-light shielding for imitting- the leading-out port of the wire rod. In this way, the covered UV resin lowers its viscosity before hardening due to radiation heat from the moving shutter of a high temperature, and a phenomenon which causes ununiformity of cover thickness such as a sag of the UV resin, by a manufacturing speed, namely, a running speed of the wire rod.
