Title: Optical recording medium
Inventor: TACHIBANA SHINICHI
IPC: G11B7/254
Filed: 1988-11-01
Abstract: PURPOSE:To prevent scratching or contamination from outside and to maintain reliability of the medium for a long time without suffering from pitting corrosion by using an UV-curing resion compound of cation photopolymerization type as a protective layer. CONSTITUTION:The UV-curing resin compound of cation photopolymerization type is used for the protective layer 5. This resin contains no acrylic acid, acrylate or aclyrate group and generates no organic acid in a high-humidity atmosphere compared to conventional UV-curing acrylate resin. The components of epoxy resin compound are preferably 0.1 - 10pts.wt. organic metal compounds and 0.1 - 10pts.wt. photolytic organic silicon compounds to 100pts.wt. epoxy resin. If each component is less than 0.1pts.wt., the resin can not be sufficiently hardened. On the other hand, if it exceeds 10pts.wt., troubles occur due to decomposition products of the catalyst remaining in the resin. By this method, the medium can be protected from scratching or contamination from outside and can be maintained reliable for a long time free from pitting corrosion of the magneto-optical recording layer 3.

Title: Hot water supplying equipment operating plural apparatus in parallel
Inventor: TATSUMURA TOSHIYA
IPC: F24H1/10
Filed: 1987-10-30
Abstract: PURPOSE:To omit a solenoid valve, and to miniaturize an equipment as a whole, by connecting an overflow preventing circuit and a water ON/OFF control circuit to the surbo motor of a water rate controller in one at least of hot water supplying apparatus. CONSTITUTION:An overflow preventive circuit 9 and a water ON/OFF control circuit 10 are connected to the surbo motor 8 of a water rate controller 3 in a secondary hot water supplying apparatus 2. An input terminal for combustion signal 11 remains on low level when the apparatus 2 is not ignited. When a high level water flow signal is output from a microcomputer 12, the potential of a point 'A' is raised on high level by the intermediary of four inverters 13-16 and a diode 17, while a point 'B' becomes low level by the intermediary of three inverters 13, 14, 18 and a diode 19. Those signals are input in an IC20 for driver of surbo motor 8, and the motor 8 is actuated to drive to the direction of opening, letting water start running through the hot water supplying apparatus 2. Both points 'A' and 'B' are opened when the apparatus 2 is ignited and the input terminal for combustion signal 11 becomes high level. The surbo motor 8 is prevented from rotating by a water rate controlling signal which is input in the IC20 for driver. In such a manner the surbo motor 8 can serve as an overflow preventive device.
