Title: Sheet distribution case
Inventor: AIBA TAMOTSU
IPC: B65D5/54
Filed: 1998-03-18
Abstract: PROBLEM TO BE SOLVED: To provide a sheet distribution case which keeps strength to withstand sheet cutting at the time of use and which can be easily expanded to be folded or crushed at the time of disposal. SOLUTION: A first joint piece 12a folded from a front side plate 12 of the sheet distribution case and a second joint piece 13a folded from a rear plate 13 are fixed to the inside of an end plate 14 folded from a bottom plate 11. A cut line 21 extending toward the vicinity of a corner 12c is formed on the first joint piece 12a, while a cut line 22 extending toward the vicinity of a corner 13c is formed on the second joint piece 13a, respectively. Therefore, by falling down the end plate 14, the joint pieces 12a, 13a are separated from parts of the cut lines 21, 22, so that the end plate 14 can easily fall down. Since there remains no joint piece at the corners 12c, 13c, the case can be easily expanded to a plane for easy disposal.

Title: Magnetic disk driver
Inventor: OOBA HARUTAROU
IPC: G11B17/032
Filed: 1979-06-01
Abstract: PURPOSE:To secure clamp release while making it possible to close a cover body lightly by a rotation driving body which comes into contact with a magnetic disk, a positioning projection part which can be fit in the magnetic disk, a clamp body, a clamp operating member, etc. CONSTITUTION:While hook member 35 is hooked by stopper 39, clamp operating member 33 of a magnetic disk holds clamp body 32 at a press position opposing to a rotation driving body, but when hook part 35 is separated from stopper 39, clamp body 32 is lifted by spring 38 via hook member 35 to separate clamp body 32 from rotation driving body 7. Further, cover body 4 pushes against clamp operating member 33 to hold clamp body 32 over the rotation driving body. Therefore, in the abovementioned constitution, adjusting the tension of spring 38 makes it possible to close the cover body softly and also to secure clamp release.

Abstract: PROBLEM TO BE SOLVED: To decrease the defective steps such as carrier error, etc., and the slippage in formation patterns by a method wherein an interlayer insulating film is heat-treated at a specific temperature before laminating it on a polycrystalline thin film transistor to be cooled down at a specific coooling rate. SOLUTION: An alkali glass, etc., is used as for an insulating substrate material of an insulating unit of a liquid crystal desplay device. At this time, a 500-1000 Å thick amorphous silicon film is formed on this glass substrate 1 using a plasma CVD device. Successively, the film is annealed at 450 deg.C for 60 minutes for desorbing the hydrogen in the amorphous silicon. Next. the silicon film is crystalized by laser iradiation so as to form a polycrystalline silicon film 2 to be separated into element in a specific shape later and then an oxide films are deposited by plasma CVD process to form a gate insulating film 3. Next, the polycrystalline silicon film 2 is heat-treated in self-aligned fashion for ion-implanting activation of a source 6 and a drain 7 into the polycrystalline silicon layer 2.  Finally, the insulating glass substrate in non- shrinkage surface is stabilized at a cooling rate of about -4 deg.C/min by this heat treatment.

Title: Photodiode array
Inventor: SONOBE SHIGERU
IPC: G01J3/36
Filed: 1984-04-09
Abstract: PURPOSE:To make it possible to perform highly accurate spectrum measurement, by correcting the returning direction of reflected light from the surface of a light receiving element in a photodiode array package PDA, thereby reducing stray light. CONSTITUTION:When incident light I, which is made to be monochromatic light by a dispersing element, reaches a PDA1, the light is converged by a cylindrical lens 4, and the image is formed on a light receiving element 2. At this time, the element 2 cannot absorb the light completely, and part of the light is reflected at an angle corresponding to the incident angle and returned to the lens 4 again. The lens 4 acts as an apparent convex mirror and diverges the light to the peripheral surface of the element 2 as I0. Therefore, stray light is not yielded.
