Title: Electrical capacitance type displacement transducer
Inventor: NIRUSU AI ANDERUMU
IPC: G01B7/00
Filed: 1994-09-13
Abstract: PURPOSE:To provide an electrical capacitance displacement transducer on which a bad influence of granular and liquid contaminants is hardly exerted. CONSTITUTION:Opposite faces of two electrode groups 12, 14 relatively moved are covered with dielectric material coats 92, 94. When a contaminant enters between the coats 92, 94, the capacitance impedance between the coats fluctuates, but the dielectric constant and the thickness of the dielectric material coats 92, 94 are selected in such a manner that the capacity impedances in the dielectric material coats 92, 94 are larger than the maximum value of the above fluctuation. Thus, the value of the electrical capacitance between the electrode groups 12, 14 showing the relative position of two electrode groups 12, 14 is hardly influenced by contaminant.

Title: Metallic thin film forming equipment
Inventor: KITAORI NORIYUKI
IPC: C23C14/24
Filed: 1993-09-30
Abstract: PURPOSE:To solve the problem of dust sticking on the back coat layer at the time of forming the layer by providing the metallic thin film forming equipment with a device for allowing the material to be subjected to vapor deposition treatment to wavily travel in a vacuum vessel, a device for irradiating a metallic material in a crucible with the electron beam and a device for supplying an oxidizing gas to the vapor of the metallic material. CONSTITUTION:The Al metal 10 is irradiated with the electron beam from e.g. the electron gun 21 to melt and evaporate the Al metal 10. The tape 5 which is delivered to the evaporation region by the delivery roll 6 is guided by the guide roll 13 movable perpendicularly to allow the tape 5 to wavily travel while vapor-depositing the Al vapor on the tape 5 and to form the metallic film on the tape 5 during its traveling. Thus particularly the surface roughness of the back coat layer of the magnetic recording medium can be adjusted to a value within the desirable range. Also oxygen is supplied to the tape 5 through the oxygen supply pipes 19 from different two directions to form the metallic layer which consists of crystal grains contg. oxygen atoms on the surface of the tape 5. Since these oxygen atoms control the friction coefficient of the metallic layer, the traveling stability of the tape 5 can be improved.

Title: Infrared-ray element
Inventor: BABA HIROYUKI
IPC: G01J1/02
Filed: 1984-11-20
Abstract: PURPOSE:To improve reliability by making the thickness of a vapor-deposited film larger at the sticking surface side of a metallic ring than at its reverse surface side, and making infrared rays incident on the reverse vapor-deposited surface. CONSTITUTION:The film thickness of the vapor-deposited surface 12 at the sticking surface side of the metallic ring 25 is made larger than that of the vapor-deposited surface at the reverse surface side, and the infrared rays are made incident on the vapor-deposited surface 123 in a direction 11. Thus, the conduction resistance of the metallic ring 2 by fixation such as adhesion is decreased and the metallic ring 2 never falls. The vapor-deposited surface 13 at the side of the infrared-ray incidence direction 11 is made thin, so transmitted infrared rays 11c are reduced and reflected infrared rays 11d are increased, so the infrared energy adsorption of a high polymer pyroelectric film 3 is increased. Namely, a high-sensitivity infrared-ray element is obtained.

Title: Engine ignition device and method
Inventor: WAKAMOTO KOTARO
IPC: F02P23/04
Filed: 1998-08-31
Abstract: PROBLEM TO BE SOLVED: To efficiently ignite premixed gas wholly to reach a demanded lean limit, and to prevent increase of power consumption or consumption of an electrode in a short period. SOLUTION: An AC field 12 is applied to an ion generation range in mixed gas in a combustion chamber 4. Ions in mixed gas are thus vibrated to accelerate translation of the ions. Rotation and vibration motion of the ions are also excited. Air (oxygen atoms and molecules) and fuel (hydrocarbon compounds) are thus easy to collide with each other to increase reaction frequency. Activation energy is reduced in addition. Mixed gas is thus efficiently ignited not locally but wholly.
