Title: Molding device for disk form recording medium
Inventor: NAKAMURA TOKIYA
IPC: B29L17/00
Filed: 1981-10-07
Abstract: PURPOSE:To fix in a predetermined position a disk form recording medium molded by a pair of metallic molds capable of making contact with and being separated from each other, by providing an overflow-pressing piece which engages with an overflow part of the medium projected between the molds and prevents the medium from being separated from the surface of one of the molds. CONSTITUTION:When a lower metallic mold 7 and an upper metallic mold 8 are clamped to each other and the disk form recording medium 20 is molded, an excess of material is ejected as an overflow 21 between the molds 7, 8. The overflow 21 is inserted between an upper pawl 13 and lower pawls 14, 14' of the overflow-pressing piece 12. When the mold is opened, the overflow-pressing piece 12 is held in an overflow-pressing position by the force of air supplied into a rotary actuator 15. Since the overflow 21 is inserted between the upper pawl 13 and the lower pawl 14 of the overflow-pressing piece 12, the recording medium 20 is maintained in the lower mold 7.

Filed: 1991-07-01
Abstract: PURPOSE:To obtain high strength by shaping positioning members for a secondary image forming lens and a holding member so that an adhesive is easy to flow and making the positioning parts serve as adhesion parts. CONSTITUTION:A holder 15 and the secondary image forming lens 12 are positioned by adhering positioning pins 12A and 12B projecting from the secondary image forming lens in positioning holes 15a and 15b of the holder.

Title: Gettering method for crystal defect
Inventor: TAKANO HIROZOU
IPC: H01L21/322
Filed: 1981-10-06
Abstract: PURPOSE:To getter effectively defects induced by processes and the pollution by heavy metals by a method wherein a single crystal silicon film formed on an  insulation film is made to have an effect of gettering. CONSTITUTION:Oxygen ions 4 of high dose are implanted uniformly into the whole of a polycrystalline silicon film 3 on an insulation film 2 formed on a single crystal silicon substrate 1, and then laser beams 5 of high output are applied on the whole thereof. The polycrystalline silicon film 3 is thereby transformed structurally into a single crystal silicon film 6, while the oxygen ions are diffused uniformly into the single crystal silicon film 6. When laser beams 5' of different output from that conditioning the monocrystallization are applied additionally to the single crystal silicon film 6, the oxygen existing on the uppermost surface of the film is diffused externally and a region 7 free from oxygen is formed on the surface thereof. Lastly it is annealed in a non-oxidizing ambience at the temperature of 600-800 deg.C and thereby  a region 8 wherein minute defects having oxygen educt as nucleus, and a region 9 wherein no defect is generated, are foumed. Thus, only an active region wherein a device is formed is made free from defects, and the crystal defect and the pollution by heavy metal can be gettered by the minute defects generated in high density.

Title: Method for dehydrating water containing suspended solid
Inventor: HASHIMOTO SUSUMU
IPC: C02F11/12
Filed: 1988-06-28
Abstract: PURPOSE:To continuously and repeatedly dehydrate only water from water contg. suspended solid by bringing water contg. suspended solid into contact with a dehydrating agent made of reversible thermal responsive resin via a water permeable layer and then heating the dehydrating agent. CONSTITUTION:Water contg. suspended solid is absorbed by bringing water contg. suspended solid into contact with a dehydrating agent made of reversible thermal responsive resin which is obtained by polymerizing vinyl monomer having oxyalkylene ether group and a cross-linking agent and the other vinyl monomer in accordance with necessity via a water permeable layer which permeates water but does not permeate suspended solid. The dehydrating agent is reutilized by heating it to discharge the water absorbed to this dehydrating agent. By the above method, the water contg. suspended solid can be easily solid-liquid separated. Further since water discharge treatment is enabled by heating the dehydrating agent, operation is made simple and the need for a specific installation is eliminated. Furthermore water absorption capacity close to the early stage is restored at a time of reutilization of the dehydrating agent subjected to water discharge treatment.

IPC: H01L21/027
Filed: 1989-06-23
Abstract: PURPOSE:To prevent the abnormality of a drawing pattern due to the positional change of a sample during drawing by installing a leaf spring, to which a strain gage pushed by a sample is mounted, to a sample holder. CONSTITUTION:Leaf springs 3 are set up onto the side face of a groove, into which a mask is inserted, in a sample holder 1, a strain gage 5 is fitted on the rear side of a surface brought into contact with the mask, and the state of bending can be detected as the change of resistance.

When the mask is displaced and separated largely from the side face of the groove, inversely, the bending of the leaf springs 3 is reduced. Accordingly, when the state of bending is measured by the strain gage, nondefective or defective positional relationship and a change thereof can be measured.
