Title: Soft x-ray transfer mask for step and repeat and manufacture thereof
Inventor: IIDA YASUO
IPC: G03F1/00
Filed: 1985-05-17
Abstract: PURPOSE:To eliminate problems such as film thickness distribution, a stress between materials, degassing and deformation of an Si frame by composing of a structure that the periphery of a transmitting film formed with a soft X-ray absorber pattern is supported by the frame and a fixing jig provided with a penetrating part corresponding to the pattern, and securing the opposite side of the film of the structure to the side having a film through an alloy layer of Si and metal. CONSTITUTION:A silicon nitride film 3 is accumulated on the opposite side accumulated with a soft X-ray transmitting film 2, and selectively worked to form a window shape 4 to become a soft X-ray passing part. The Si of the window is removed, and an X-ray transmitting film 5 pulled to the Si frame is formed. Then, a soft X-ray absorber pattern 6 of Au or the like is formed. Subsequently, a jig for securing the frame is set in a range of approx. + or -50mum of the thickness of the frame on an Si plate of rectangular profile and polished on both sides with high flatness with a penetrating part 8 wider than the soft X-ray passing window for an error of matching therebetween and a dug part 10 wider than the frame in the shape of the frame.

Title: Facsimile storage converter
Inventor: HANABE KENICHI
IPC: G06T1/60
Filed: 1979-08-20
Abstract: PURPOSE:To reduce the deterioration of picture quality by storing the position and quantity of a rejected picture information and by substituting a signal component rejected in transmission with a picture signal of the adjacent scanning line. CONSTITUTION:Line memories A2 and B3 are stored with 1-line facsimile signals passed through A/D converter 1, but when the following signal arrives while two surfaces of the memory are full up, line memory control circuit 4 actuates counter 14 for the number of rejected scanning lines, which is stopped on arrival of the transfer command from storage part 9 to inform storage part 9 of its count value, transferring a picture signal for one line successively. Storage part 9 remembers the count value and the start position of a rejected scanning line and when the scan reaches the position of the rejected scanning line in transfer to transmission part 10, preceding-line substraction of a frequency equivalent to the number of rejected scanning lines is commanded to transmission part 10. Thus, a scanning line lost due to an overflow in reception is substituted with the preceding line to eliminate its absence, thereby reducing the deterioration of picture quality.

IPC: G02B6/44
Filed: 1984-05-25
Abstract: PURPOSE:To form a low-loss optical fiber of which the transmission loss owing to diffusion of hydrogen molecules and OH group changes extremely less with lapse of time by enclosing a core in the position apart by at least >=2 times the core diameter from the core so that a hydrogen diffusion preventive layer exists internally in the clad part. CONSTITUTION:The optical fiber consists of the core part 4 (10mum diameter) in which light is propagated, the inside clad layer 3 (60mum diameter) on the inside in which the light is confined, the layer 1 (about 0.1mum layer thickness) for preventing hydrogen diffusion and the clad layer 2 on the outside consisting of a support tube or jacket tube. The clad part consists of the clad layer 3 on the inside and the clad layer 2 on the outside. The hydrogen diffusion preventive layer is about 0.1mum and is satisfactory as far as said layer is formed to the thickness at which the diffusion or hydrogen is prevented or above. The manufacture of the optical fiber contg. internally the hydrogen diffusion preventive layer is also made possible by using a quartz tube deposited preliminarily with silicon oxynitride by chemical evaporation on the inside surface in the stage of coating the quartz tube on a glass rod manufactured by a vapor phase axial deposition method.

Filed: 1987-04-30
Abstract: PURPOSE:To stop circuit operation before a big accident such as a fire takes place by detecting it from a change in the resistance of a thermosensing element if a fault such as a short-circuit takes place in a flyback transformer and the transformer is locally heated abnormally so as to stop the high voltage generation permanently. CONSTITUTION:The inside of the flyback transformer 1 is divided equally into three axially and thermosensing elements 21, 22, 23 are arranged respectively in 1st, 3rd and 5th sections of a low voltage bobbin 3. If a short-circuit or the like takes place in the flyback transformer 1, the inside of the flyback transformer 1 causes abnormal heating locally. The resistance of a thermosensing element near abnormal heat source of the faulty point is remarkably increased among the thermosensing elements 21, 22, 23. As a result, a bridge circuit 24 is unbalanced. Thus, a thyristor 36 is conductive and a current from a flyback power supply 15 flows to ground through a fuse 38 and the thyristor 36 to blow the fuse 38.

Abstract: PURPOSE:To improve the throughput of a file system by removing a defective track when the defective track is present and redistributing data. CONSTITUTION:A track decision part 160 detects a defective track among plural tracks to which data divided in parallel are assigned. When there is the defective track present among the tracks to which the data are assigned, a buffer memory 110 is stored with digital data assigned to the defective track.
