Title: Recording medium and recording and reproducing method
Inventor: OMICHI TAKAHIRO
IPC: G11B11/12
Filed: 1988-09-08
Abstract: PURPOSE:To obtain the optical recording medium which allows erasing with high sensitivity by using a metal complex of a cyano group-contg. electron receptor of which the electrical conductivity is reversibly changed by irradiation of laser light as a medium and detecting the recording signal as a change in electrostatic capacity value. CONSTITUTION:The medium is formed by providing a transparent conductive film 2 contg. indium oxide or tin oxide on a transparent substrate 1 and further providing the recording layer 3 consisting of the metal complex of the cyano group-contg. electron receptor thereon. The medium is irradiated with the laser light stopped down by a lens 4 from the substrate 1 side to change the part irradiated with the laser to an electrical conductor in order to make recording and reproducing by using this medium. The change in the electric resistance is detected as the change in the electrostatic capacity value. The change in the electrical conductivity is read with good sensitivity by using a reproducing stylus 54. The irradiated part returns to an original insulator when the medium is irradiated with defocused laser light. The optical recording medium which allows erasing with the high sensitivity is obtd. in this way.

Filed: 1998-08-06
Abstract: PROBLEM TO BE SOLVED: To provide high shape precision and outer appearance quality in a short period of time by magnetically polishing a work while supplying slurry type abrasive liquid with Al2O3, CeO2, etc., as its abrasive materials in a clearance between the work and ferromagnetic particulates. SOLUTION: A magnetic field is made on a yoke 3 by filling ferromagnetic material particulates 8 in a clearance between a magnetic pole 24 and a work at first. Continuously, relative movement of the magnetic pole 24 and the work 1 is made by a rectilinear positioning means 6 and a work rotating means 10, and a spindle 2 is rotated. Simultaneously, previously prepared slurry type abrasive liquid 9 mixed with abrasive materials suitable for polishing of the work 1, water, an interfacial active agent, an antifoamer, etc., is supplied between the work 1 and the ferromagnetic material particulates 8.  Consequently, it is possible not only to constantly supply the abrasive materials in the abrasive liquid between a surface of the work 1 and the ferromagnetic material particulates 8 in the middle of working and the abrasive liquid absorbes frictional heat due to working, and accordingly, it is possible to provide required surface roughness or outer appearance precision in a short period of time.

Inventor: YATSUDA HIROMI
IPC: H03H3/08
Filed: 1988-09-07
Abstract: PURPOSE:To realize a surface acoustic wave filter with a desired frequency characteristic by cutting the expansion electrode finger of the surface acoustic wave filter consisting of a comb shape electrode which expands gradually along a direction almost intersecting orthogonally to the propagating direction of a surface acoustic wave at an arbitrary position by a method such as laser irradiation, etc. CONSTITUTION:After the surface acoustic wave filter is manufactured by transferring the electrode pattern of the surface acoustic wave filter already designed and whose frequency characteristic is known from a photomask on a piezoelectric substrate, parts 6a and 6b of the electrode fingers 26a, 26b, 30a, and 30b are cut. Thereby, the electrode pattern with only a different passing band can be manufactured without designing it from an existing electrode pattern. Thus, it is possible to manufacture the masks of the filters with different frequency characteristics inexpensively from a sheet of expensive mask.

Filed: 1998-08-07
Abstract: PROBLEM TO BE SOLVED: To stop the discharge of acidic water to the outside by fitting a filter which allows gas generated by electrolysis to pass and checks water to the drain port formed to communicate with anode chambers. SOLUTION: Filters 13 which allow gas generated by electrolysis to pass and check water are fitted to drain ports 12 which are formed in the upper parts of anode chambers 9 and 9 and communicate with the anode chambers 9 and 9. During the alkaline water making, after pure water being sent to the anode chambers and cathode chambers 10 and 10, direct current voltage is applied between an anode and cathodes 7 and 7. The pure water in the anode chambers is electrolyzed into acidic water, and gas is generated. In this process, the generated gas is discharged from the filters 13 into the air. By the installation of the filters 13, alkaline water can be taken out continuously only by releasing gas in acidic water to the outside, and the drain of acidic water can be eliminated.

Title: Manufacture of highly porous thermoplastic resin body and mold therefor
Inventor: HAYATA SHIGENARI
IPC: B29K105/04
Filed: 1985-10-09
Abstract: PURPOSE:To obtain a low-density, highly expanded porous body by a method in which inner parts set in molds are allowed to jump out through parting lines from the outer frame at the same time as the molds are opened and a resin is expanded without limitation of the molds. CONSTITUTION:Inner parts 3 and 6 to be jumped out are housed in an outer frame 2 to build up a bottom form B. A thermoplastic resin containing a blowing agent is cast into the cavity 11 of the form B, a cover mold A is put on the form B, and the forms A and B are closed by applying a push pressure to the form B and heated. When the expansion force of the resin increases, the push pressure is removed out of the form B, whereupon the mold are separated into the bottom form B and the cover form A by the expansion force and the resin is jumped out of the cavity 11 by the expansion force. The inner parts 3 and 6 in the form B are then jumped out from the outer frame 2 and decomposed. Since the surface of the resin D is relieved of limitation of the molds at all, the resin D is freely expanded in every direction and a desired highly porous body can be obtained.
