Title: Molding method of unspherical optical element and its device
Inventor: NAGAYAMA NORIMITSU
IPC: B29K105/24
Filed: 1990-05-18
Abstract: PURPOSE:To suppress the deformation due to the shrinkage in curing by a method inwhich light is radiated on the layer of photocurable transparent resin, and then its curing and shrinking are started, and simultaneously a mold is lowered coincidently with the shrinking speed in the direction of optical axis, and then molding is achieved. CONSTITUTION:A mold release layer 15 is formed on a mold 7, and the layer of coupling agent is formed on a lens-blank 10. After the resin of ultraviolet ray-curable type has been ejected on the lens blank 10, it is placed on the stepped part 11 of a through hole 8, and the mold 7 is lowered, and then the distance between the mold 7 and the lens blank 10 is made equal to the central thickness of the desired optical element to be molded X (1 + the shrinkage facture in curing of the resin to be used). Then ultraviolet rays are radiated on the resin 7 of ultraviolet ray-curable type, and simultaneously with the beginning of curing and shrinking, an air cylinder is released, and then after several seconds, the pressing jig 18 of a template is moved, thereby releasing the hold of the template 4. Then since the resin 17 of ultraviolet ray-curable type is closely stuck to the mold 7, the mold 7 is lowered in such a manner that it is pulled coincidently with the shrinkage in curing of the resin 17 of ultraviolet ray-curable type. After curing, it is released from the mold, and a molded composite optical element can be obtained.

Title: Manufacture of semiconductor device
Inventor: HORIUCHI MITSUAKI
IPC: H01L27/10
Filed: 1988-05-27
Abstract: PURPOSE:To prevent the reliability of a semiconductor device from decreasing upon melting of a fuse by locally radiating an energy beam from above an insulating film covering the metal wirings of an integrated circuit to anneal a predetermined position at a high temperature, and then annealing a semiconductor substrate at a low temperature to cut the predetermined position of the metal wiring. CONSTITUTION:The cutting position of aluminum wiring 11a is radiated with an energy beam L such as a laser beam in a spot state from above a passivation film 12 to locally anneal the wiring 11a at a high temperature. Then, when a substrate 1 is annealed at a low temperature, a stress migration occurs by the diffusion of aluminum crystalline grain boundary at the position where is radiated with the beam 1. As a result, the wiring 11a is disconnected, rows and columns including defective bits are replaced with a redundancy circuit. Accordingly, since the wiring of the disconnected position is not melted different from a fuse melting type, there is no apprehension of reducing the reliability of the wiring different from that the flying splash of the melted wiring becomes a foreign matter.

Title: Recording medium
Inventor: SHIMADA FUMIO
IPC: G11B7/24
Filed: 1982-07-23
Abstract: PURPOSE:To obtain a recording medium with high sensitivity which can be consecutively produced, by applying a picture signal to a layer containing an optical hardening agent and a binding agent when necessary in a layer containing a physical phenomenon uncleus, then making the reflecting property of the recording medium to a pattern mode. CONSTITUTION:A supporter 1 is provided, and a photosensitive layer 2 contains a physical phenomenon nucleus and an optical hardening agent. These materials dispersed into a binding agent are usable. A track forming pattern 3 has an extremely small width. An active light beam 4 uses ultraviolet rays, electron beams, etc. and produces a photochemical reaction to the optical hardening agent. Thus the picture exposure is provided on a recording medium. A metallic compound containing layer 5 is removed for the physical phenomenon nucleus by exfoliation, dissolution or peel apart process, etc. The layer 5 can be exfoliated effectively by hardening previously the physical phenomenon nucleus layer 2, i.e., a recording layer with a film hardening agent.

Title: Optical disk stopper
Inventor: HARADA HISAO
IPC: G11B7/24
Filed: 1990-05-19
Abstract: PURPOSE:To prevent an optical disk from being slipped down in the case of carrying it by a hand by allowing the shape of the outer peripheral surface of the disk to be rugged. CONSTITUTION:Since no ruggedness is present on an outer peripheral surface 1 of a conventional disk and it is made flat against a circumference. Therefore, when the part is picked up by fingers to put in/out the disk to a disk storage case, setting/ejecting it to a player or moving it, etc., the disk is easily damaged and cracked by being dropped down. On the other hand, since the outer periph eral surface 1 is easily slipped off and damaged, the user feels uneasiness in the case of carrying the disk. Then, rugged shaped 5 are formed on the outer peripheral surface 1 of the optical disk (compact disk, laser disk) so that it is hardly slipped down in the case of carrying the disk by the hand. Thus, in the case of carrying the disk by the hand, it can be prevented from being slipped down.

Title: Printing apparatus
Inventor: OKAMURA YASUSHI
IPC: B41J11/42
Filed: 1983-07-15
Abstract: PURPOSE:To make it possible to prevent direct printing to a platen, by subtracting a reversal paper feed amount from a positive paper feed totaled amount while comparing the totaled amount and the reversal paper feed amount to control the reversal paper feed amount. CONSTITUTION:When a data discriminating means 2 receives printing data from a host computer 1, said means 2 drives a printing mechanism part 9 to perform printing. When signal is received by said means 2, the platen of a paper feed drive part 8 is rotated through a positive and reversal rotation judge means 3 and positive paper feed is totaled by an operation means 4 to be stored in a memory means 5. When the absence of paper is detected by a paper detecting part 7, a printer is stopped. On the other hand, when a reversal paper feed signal is received, the paper feed totaled amount and the reversal paper feed amount are compared by a comparing means 6 and, if the reversal paper feed amount is small, the paper feed drive part 8 is reversed and a subtracted paper feed amount is stored in a memory means 5. When this memory amount reaches zero, the printer is stopped. By this mechanism, direct printing to the platen can be prevented.

Title: Orientation device for turret hear spindle
Inventor: ABE HARUO
IPC: B23Q15/22
Filed: 1987-05-28
Abstract: PURPOSE:To remove a cutter mark at time of precision boring as well as to make special form backside machining performable by rotatively positioning a spindle to the orientation as a position coder recognizes a turning position of the spindle. CONSTITUTION:A position coder 30 is turned by rotation of a gear 19, whereby a position where a first piece 1 and a second piece 2 are engaged with each other by rotation of a drive motor 11 is made detectable by the position coder 30. When this detected turning position of a spindle 5 differs from the specified turning position, a turning angle signal to be rotationally compensated is emitted out of the position coder 30, and with this signal, a control device rotates the drive motor 11 as far as a portion for the angle, and thereby the spindle 5 can be rotatively positioned to the specified position. Consequently, a cutter mark at time of precision boring is removed, and special-form backside machining can be done.
