Abstract: PURPOSE:To make it possible to start image recording immediately after completing the initial operation of a color image recording part by providing the image recording device with a printer for forming a masking original sheet, a color image recording part and a masking original sheet feeder and allowing a control part to drive the masking original sheet feeder simultaneously with turning on a power supply for the color image recording part. CONSTITUTION:The image recording device is provided with a monochromatic laser printer 11 for forming each masking original sheet 10 and the color image recording part 20, and the printer 11 and the recording part 20 are allowed to interlock with each other through the control part. When the power supply of the recording part 20 is turned on, an automatic masking original sheet feeder(ADF) 13 can be driven by the action of the control part and masking original sheet 10 can be outputted from the printer 11 before completing the initial operation of the recording part 20. The printer 11 forms the sheet 10 simultaneously with the completion of the start of the recording part 20 independently of the operation enabled/disabled state of the recording part 20 and the ADF 13 immediately sends the sheet 10 to the recording part 20. Consequently, the recording part 20 can obtain the sheet 10 simultaneously with the completion of its initializing operation and start exposure.

Abstract: PURPOSE:To prevent the strength of a hollow tubular body in which the tapering rate changes abruptly, such as an angling rod or the like, from lowering by a method wherein a prepreg is wound round a tapered mandrel, in which the tapering rate changed abruptly, and, after that, high strength fiber yarns are braided cross-wise throughout before and behind portions, across which the tapering rate changes in order to bring the prepreg into close contact with the mandrel. CONSTITUTION:After a prepreg 2 is wound round a tapered mandrel, in which the tapering rate changes in (a), (b) and (c) in the order named from the tip in such an abrupt manner that the difference between the tapering rates at the boundary portion, across which the tapering rate changes, is 15/1000 or more, high strength fiber yarns 3 are braided cross-wise throughout before the boundary portion, across which the tapering rate changes from (a) to (b) and behind the boundary portion, across which the tapering rate changes from (b) to (c) in order to bring the prepreg 2 over said portions into close contact with the mandrel 1. Next, a tightly binding tape 4 is helically bound from one end of the prepreg 2 by conventional procedure. Further, heat curing treatment, mandrel releasing treatment and tape peeling- off treatment are performed in the order named in order to manufacture a hollow cylinder.

Title: Lead frame
Inventor: OGASA NOBUO
IPC: H01L23/28
Filed: 1982-07-19
Abstract: PURPOSE:To obtain a lead frame which has thermal diffusion property and high reliability and whose cost is lower than that of the lead frame made of Kovar or Fe-Ni alloy and a little higher than that of Cu alloy by a method wherein the entire surface of the Cu alloy frame which is previously processed to a fixed lead frame form by punching or etching processes is coated with Fe-Ni alloy wherein the weight ratio of Ni is controlled. CONSTITUTION:The reason why the weight ratio of Ni in the Fe-Ni alloy is regulated to 30-60% is: 30% or less does not enable to obtain a uniform and stable configuration of face centerred cubic lattice, rust is liable to generate under preservation in the air, the most part of the oxide film structure at the time of heating is occupied by FeO or Fe3O4, and accordingly the sealing property at the time of resin sealing decreases; 60% or more enables Ni oxide to occupy the most part of the oxide film at the time of heating, the Ni oxide layer is difficult to be removed in flux treatment before dipping to a solder bath when the exterior is plated with solder at the time of IC assembly, and then solder wetting becomes worse. The thickness of the Fe-Ni alloy coated layer applied over the surface of a Cu or Cu alloy substrate or of a clad tape substrate with Cu as the surface layer is set to 0.5-5.0mum.

Title: Manufacture of semiconductor device
Inventor: YAMASHITA TSUTOMU
IPC: H01L23/50
Filed: 1982-07-19
Abstract: PURPOSE:To enable to mount smoothly without generating lead bending and poor opening by a method wherein the lead part is cut to the form that it becomes the crest at the center in the lead top end width direction after cutting and then projects, using a wave cutting edge, when it is cut off from the lead integrating frame part to an independent lead. CONSTITUTION:Positioning is so performed that each top on the mountain side of the wave part of a base 6 having the same pitch P2 as the pitch P1 between outer leads agrees with the center in the width direction of each of the outer leads 2 by a method wherein the end side part of the outer lead integrating frame 4 in the state that the top end toward the inner direction of each of the outer leads 2 of the outer lead integrating frame is sealed in the main body 1 of a package is struck and contacted on a stopper 5 which serves as the reference for positioning. After fixing by positioning, the lead can be cut to the form that the top end toward the outside of each lead project in mountaneous manner by pushing down the wave cutting edge (not illustrated) which meshes with the wave part of the base 6. When one side outer lead is cut off, and next the other side one is cut off, both side outer leads can be cut to the form that the center position in the top end width direction accurately becomes at the top of the mountain, even in the case that both side outer leads slip comparatively to slight degree.

Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To judge working propriety before attaching a cup by a simple constitution by performing the centering for attaching the cup while observing the image of a lens to be worked inputted and displayed on a display. SOLUTION: An operator moves the lens LE to be worked on a screen plate 3 so as to match a mark point-marked image of the center of a mark point image with the center of a cross reticule mark while observing the display 22 of a lens working device 20. Also, the lens LE to be worked is rotated and axis accuracy is matched so as to overlap the left and right marked images of the mark point-marked image with the horizontal line of the cross reticule mark. Thus, the centering of the lens LE to be worked is completed. The operator judges the working propriety of whether or not a lens diameter is insufficient by observing the diameter of a lens image and a lens-shaped graphic at the time. Then, when it is judged that the diameter of the lens to be worked is not a problem, the cup C is attached by a cup attachment part 10.
