Abstract: PROBLEM TO BE SOLVED: To enable the control of a single electron level, including the thin line region and microbox region by forming microbox regions formed on a length part of the thin line region on an insulation film formed on a length part of the thin line region. SOLUTION: By using as a mask a resist pattern 9 extending perpendicularly to the length of a thin linear pattern 8, a SiO2 film 6a is patterned into a thin linear pattern and etched. A polysilicon film 5a formed into a thin linear pattern is etched. A silicon film 3a formed into a thin linear pattern and a polysilicon film 5b formed into a thin linear pattern are etched in the side direction from the side faces to thereby reduce the width of this film 3a, thus forming a quantum thin line 3b of about 30nm wide and reducing the plan shape of the polysilicon film 5b to obtain a quantum box 5c of about 30nm in side length. The position of a microbox region about the length direction of the quantum thin line is determined by the positioning at the time of forming of the resist pattern 9.

Title: Material for multiple optical recording medium
Inventor: NAKANO ATSUSHI
IPC: G11B7/2472
Filed: 1988-12-23
Abstract: PURPOSE:To reduce an S/N ratio and increase multiplicity by using an organic color H-associate with a peak of an absorption zone which has a narrower linear width at a short wavelength side and higher absorption intensity than a peak of the absorption zone of an organic color monomer. CONSTITUTION:Cyanine color shown by structural formula is dissolved with extremely purified water, and NaO is dissolved with this aqueous solution so that the pH value reaches 10 or more. Next, stearic acid is dissolved with chloroform to prepare a chloroform solution and this solution is developed on the water phase of the cyanine color solution to obtain a composite monomolecular film of stearic acid and cyanine color. In this case, if the surface pressure of the composite monomolecular film is 50mN/m or more, the film breaks down. In addition, the film is subjected to a continued compression, the composite film of stearic acid and cyanine color can be obtained which constitutes a H-associate. This material has a peak of about 460nm of an absorption zone at the short wavelength side, so that it absorbs a short wavelength laser beam efficiently and high-density recording is ensured.

Title: Polarized electromagnet
Inventor: YOKOYAMA YOICHI
IPC: H01H51/22
Filed: 1987-12-23
Abstract: PURPOSE:To improve magnetic efficiency at the time of energizing and to obtain a sufficient attraction force of a polarized electromagnet for moving a core longitudinally of a pole piece by the energization of a coil by disposing the pole faces of any pole piece and the core for forming one or two main air gaps in a nonfacing manner at the time of nonenergizing, and extending the end of the piece to the core, or the end of the core to the pole piece. CONSTITUTION:The end of a yoke 6 at the opposite side to an L-shaped piece 6a is extended to an armature piece 5, the length of the piece 5 is shortened as compared with the size between both the yokes 6 and 6 to be inserted between the two yokes 6 and 6, thereby providing an air gap of a leakage type. A magnetic flux phi1 flows in a nonenergizing state. When a coil 1 is energized, a magnetic flux phi2 tends to flow. In this case, in a main air gap (3), the distance between the pole face of the end face of the yoke 6 and the pole face of the end face of the armature piece 5 is approached, thereby reducing its magnetic resistance. Accordingly, the magnetic resistance of the whole loop of magnetic flux phi2 is reduced at the time of energizing, thereby improving its energizing efficiency.

Title: Thermostat for mixing valve for water combination faucet
Inventor: MATSUMOTO DAIJI
IPC: F16K31/68
Filed: 1995-11-10
Abstract: PROBLEM TO BE SOLVED: To smoothen a water flow and prevent the occurrence of pulsation even when a pressure difference between water and hot water is high by a method wherein a sheet metal fitting to close one end side of the cylindrical body of a thermostat forms a taper surface the diameter of which is decreased along the direction of a flow passage. SOLUTION: At a mixing valve for water combination faucet, water and hot water flowing in a housing 10 through a water inflow port 11 and a hot water inflow port 12 are mixed in a mixing chamber. A temperature-sensitive expansion contraction substance 15 retracts a protrusion 15a at a tip according to the sensing temperature of mixture water in the mixing chamber. By effecting fine adjustment of the position in an axial direction of a spool valve 16, automatic regulation to a set temperature is effected. In a thermostat 22, the shape of a sheet metal fitting 13 forms a taper surface 23 having diameter which is decreased along the direction of a flow passage. This constitution forms a flow passage for water formed by using the taper surface 23 and the inner peripheral surface of the spool valve 16 in such a manner to gradually spread.  Thereby, even when a pressure difference between a feed pressure of water and a feed pressure of hot water is high, water smoothly flows and the feed pressure thereof exercises no adverse influence on the spool valve 16.
