Title: Ice making device for refrigerator or the like
Inventor: ONISHI KENJI
IPC: F25C1/18
Filed: 1988-07-15
Abstract: PURPOSE:To obtain an ice making plant which is capable of generating transparent water efficiently by comprising a first cooling period which actuates a cooling means consecutively, a second cooling period which actuates a heating means, and a third cooling period which stops said heating means in succession to the second cooling period, and actuates said cooling means consecutively. CONSTITUTION:A first cooling period during which water reaches 0 deg.C is subject to a cooling action from a cooling plate 13 so that water is cooled rapidly. Similarly, water is rapidly cooled and turned into hard ice during a third cooling period during which freezing has completed. With regards to a second cooling period during which freezing has advanced, a heater 11 is actuated, synchronizing with the action of the cooling plate 13, thereby producing the equilibrium between cooling and heating and advancing ice making from the bottom to the top at a specified freezing speed. When the cooling means has not operated for a long time, the heater 11 fails to operate as well. When the temperature of a water temperature sensor 35 drops below a specified value, the heater 11 operates so that water may not be frozen starting with the water surface without actuating the heating means for a long time.

Title: Composite type magnetic head and its production
Inventor: YAMAMOTO HIROSHI
IPC: G11B5/187
Filed: 1988-07-14
Abstract: PURPOSE:To prevent contour effect from occurring at the time of reproducing a recorded signal and to prevent the stripping-off of a metallic magnetic film and fine crack on a boundary between the magnetic film and the block of magnetic material from occurring by making a surface which is contact with a part equal to the track width of the half of a core consisting of the magnetic film non-parallel with the surface of a gap. CONSTITUTION:The part equal to the track width Tw of a magnetic head which abuts on a recording medium is processed to be oblique to the gap G with the same wheel that is used in processing a groove for regulating said width Tw. After such a process, by applying the metallic magnetic film 3 and grinding the surface of the gap, a specified gap material 4 is formed. Thereafter the halves 1a and 1b of the core block are melted and firmly fixed with glass. Thus, the boundary between the block of magnetic material 2 and the metallic magnetic film 3 is made non-parallel with the magnetic gap G. Thus, the contour effect caused by the loss of deviation in the angle of a gap can be prevented. The stripping-off of the magnetic film 3 of a narrow track part and the occurrence of the fine crack on the boundary between the metallic magnetic film 3 and a substrate can be prevented.

Filed: 1994-07-29
Abstract: PURPOSE:To provide a combination mat which can be assembled and disassembled and is convenient for carrying in the mat to be laid on the projecting- recessed ground surface or mud. CONSTITUTION:Holes 6 and claws 5 of mutually adjacent respective mat boards 1 are fitted to each other in a vertically overlapping shape.
