PROBLEM TO BE SOLVED: To realize an epitaxial rare earth oxide (110)/silicon (001) structure by well epitaxially growing a rare earth oxide such as cerium oxide of the (110) face orientation on a silicon substrate of the (001) face orientation at a lower growth temperature than that of a conventional method. SOLUTION: The surface of an Si substrate 1 of the (001) face orientation is converted into a dimer structure by surface reconstruction of 2×1 and 1×2 and a raw material comprising at least one or more kinds of rare earth elements is used in an atmosphere containing an oxidizing gas to epitaxially grow a cubic or a tetragonal rare earth oxide, e.g. a CeO2 membrane 2 of the (110) face orientation. At the time of the growth, the feed of the oxidizing gas to the surface of the Si substrate 1 is started and the feed of the raw material comprising at least the one or more kinds of the rate earth elements is then carried out.

PROBLEM TO BE SOLVED: To produce a lithium triborate (LiB3 O5 ) single crystal free from crystal defect and having high quality at a low cost. SOLUTION: A single-zone furnace 1 is used as a growth furnace, a seed crystal 16 is brought into contact with a molten liquid 14 containing a flux in the growth furnace 1 and the seed crystal 16 is pulled up from the molten liquid 14 to effect the deposition and growth of a lithium triborate (LiB3 O5 ) single crystal on the seed crystal 16. The growth azimuth in the above process is selected to be a-axis or b-axis.

PURPOSE:To make equal the coeffs. of thermal expansion of a nonmagnetic base and thin magnetic film and to obviate the exfoliation of the thin magnetic film and the deterioration of the magnetic characteristic in a magnetic head combined and united with the nonmagnetic base and thin magnetic film by consisting the nonmagnetic base of a specific ceramic compsn. CONSTITUTION:The Na2O-Ta2O5 ceramic compsn. is used as the nonmagnetic substrate. The Na2O-Ta2O5 ceramic compsn. has the compsn. expressed by the generation formula xNa2O.yTa2O5 and the compsn. range thereof is set at 0.85 / deg.C which is too small as compared to the thin magnetic film is x/y is / deg.C when x/y is set at 0.85

PROBLEM TO BE SOLVED: To provide a switch, an operating button, an input device, a key input device, an electronic apparatus and an apparatus having low power consumption and very simple structures, wherein a feeling of operation or a feeling of touch is clear, a feel about whether a switch or an operating button is pushed or not is clearly transmitted. SOLUTION: In a thin switch provided with a lower electrode 101 and an upper electrode 102 facing each other, a stress emitter film 105 is closely fixed to the surface of an outer cover 104. Once the thin switch is pushed with a finger, the lower electrode 101 is brought into contact with the upper electrode 102 to make them conduct each other. At the same time, light is emitted from the stress emitter film 105 to cause a color change. A piezoelectric element is provided on the rear surface of the thin switch, and when the lower electrode 101 is brought into contact with the upper electrode 102 to make them conduct each other, vibration produced by driving this piezoelectric element may be transmitted to the finger.

PROBLEM TO BE SOLVED: To obtain an artificial luminous hair structure which is readily luminous even only by contact with the human hand and yet is luminous only when the human hand is brought into contact with the structure, artificial luminous skin, an artificial luminous cloth, etc. SOLUTION: The artificial luminous hair structure is made by forming an artificial luminous hairs 12 from a composite material of an inorganic compound particle composed of a stress luminous material and an elastic body and standing the artificial luminous hairs 12 on a substrate 11 in a regular location. SrAl 2 O 4 :Eu, etc., are used as the inorganic compound particle. An epoxy resin, a polyester resin, etc., are used as the elastic body. The artificial luminous hair structure is used as artificial luminous skin. An artificial luminous yarn is formed from the composite material and the artificial luminous cloth is woven using the artificial luminous yarn. COPYRIGHT: (C)2004,JPO

PROBLEM TO BE SOLVED: To easily obtain a luminescent oxide single crystal having a target composition and sufficiently large crystal sizes. SOLUTION: The luminescent oxide single crystal having the composition expressed by general formula A x B y O z is grown by a flux process. In this case, the single crystal is grown by feeding raw materials under feeding composition conditions satisfying a/b>x/y when the molar number of A produced from the first raw material containing A is defined as (a) and the molar number of B produced from the second raw materials containing B as (b).

PROBLEM TO BE SOLVED: To provide an actuator using an intercalation substance that becomes a new mechanochemical system, and a driving method and system therefor. SOLUTION: This actuator is structured by using the intercalation substance, and the driving system is structured by the actuator and the solution supply system. A host substance of the intercalation substance includes at least one kind of an inorganic or organic layer substance, and a guest substance is ions or molecules existing in a solvent. The guest substance accompanied with the molecules of the solvent is put in/taken out between layers of the host substance, thereby generating displacement.
