A technology which is capable of an accurate measurement of the film thickness even if an exfoliation occurs is provided. A difference frequency Δf0 is calculated from a resonance frequency f0 of a film thickness sensor at a current time a0 and a resonance frequency f1 at an immediate past time a1, and whether the exfoliation has occurred or not is detected from its sign and a comparison result relative to a reference value. When the exfoliation has occurred, a corrected film thickness value T′ is obtained by adding the thickness Δt0 of the exfoliation film to an increased film thickness value T which is determined from a resonance frequency fx measured at a future time ax to be converted to the thickness of a film on a film forming object, and whether the formation of the film should be terminated is judged in comparison to an aimed value. Thus, even if the exfoliation occurs in the film thickness sensor, the film thickness value of the thin film on the surface of the film forming object can be accurately obtained.

Disclosed is a cooling apparatus including a heat sink, a blower mechanism, an opening member, and a movement mechanism. The blower mechanism has a blower opening that has a predetermined area and is opposed to the heat sink. The opening member has a first opening that has an area smaller than the area of the blower opening. The movement mechanism moves the opening member so that switching between a first state and a second state is performed. The first state is a state in which the first opening is disposed between the blower opening and the heat sink, and the second state is a state in which the first opening is removed from between the blower opening and the heat sink.

A heat sink includes a heat-transfer container incorporating a flow path through which a cooling fluid flows, for cooling a heating element in contact with the heat-transfer container The flow path includes a first cross-sectional portion that becomes narrower as the distance between a given point in the flow path and a side of the heat-transfer container which makes contact with the heating element becomes longer in a direction perpendicular to the direction in which the cooling fluid flows, and a second cross-sectional portion that is approximately constant in the direction perpendicular to the direction in which the cooling fluid flows. The first cross-sectional portion and the second cross-sectional portion alternately continue in the direction in which the cooling fluid flows causing a three-dimensional flow so the heat-transfer properties are enhanced with a simplified structure.

An optical pickup apparatus includes a diffractive optical element, and an objective lens that focuses a light beam of a first wavelength λ1, a light beam of a second wavelength λ2 and a light beam of a third wavelength λ3 on a first recording medium, a second recording medium, and a third recording medium, respectively, the wavelengths λ1, λ2, and λ3 being different from each other. The diffractive optical element includes a first diffractive surface that neither diffracts the light beam of the first wavelength λ1 nor the light beam of the third wavelength λ3 but diffracts the light beam of the second wavelength λ2, and a second diffractive surface that neither diffracts the light beam of the first wavelength λ1 nor the light beam of the second wavelength λ2 but diffracts the light beam of the third wavelength λ3, and each of the first and second diffractive surfaces satisfies the following condition inequality: Λ/λ≧8 wherein Λ represents the minimum pitch in the case that the width which generates a phase difference of one wavelength when the closest wavefronts resulting from adjacent steps in each of the diffractive surfaces are linked with each other is defined as one pitch, and λ represents the wavelength of the diffracted light.
摘要:
The rotation of axial-flow blades permits air entered through an inlet port to exit directly to outside of a case in the axial direction, and the rotation of centrifugal blades permits air entered through the inlet port to exit through a side surface outlet port to the outside of the case in the centrifugal direction. Accordingly, the amount of flow of air exiting from inside of the case can be increased so that the amount of heat dissipation is increased. It is therefore able to provide a cooling apparatus and electronic equipment mounting the cooling apparatus with improved cooling efficiency while achieving a small thickness.

An outboard engine unit having heat-generating electrical equipment. An intake port of an intake silencer is set at a distance from an engine, and air suctioned from the intake port is unlikely to be affected by heat produced by the engine. Electrical equipment is disposed in a direction of opening of the intake port, and air around the electrical equipment thereby circulates when air is suctioned from the intake port.

Proposed is a height adjusting mechanism for a tiller handle (23) of an outboard motor (1). An adjustment piece (45) is detachably attached to the front end of a handle support bracket (22) which extends rearwards from the outboard motor main body (3). The adjustment piece is configured to be attached to the front end of the handle support member in two or more different positions and provided with a corresponding number of spacer portions (47-50) having different thicknesses so as to interpose a selected one of the spacer portions between corresponding stopper surfaces (41, 42) of the tiller handle and handle support bracket depending on the positions of the adjustment piece. Thereby, the height adjusting mechanism for the tiller handle is avoided from protruding laterally or vertically from the base end of the tiller handle so that the external appearance is not impaired and interferences with the surrounding parts can be effectively prevented. Also, the height of the tiller handle can be selected from two or more possible positions.

A resin composition for forming a top coat which can be formed on a photoresist film without causing intermixing with the photoresist film, can maintain a stable film coating which is not eluted into a medium during immersion lithography, does not impair pattern profiles during dry exposure (which is not immersion lithography), and can be easily dissolved in an alkaline developer. The resin is a copolymer which comprises at least one recurring unit (I) selected from the group consisting of a recurring unit having a group shown by the following formula (1), a recurring unit having a group shown by the following formula (2), and a recurring unit having a carboxyl group, and a recurring unit (II) having a sulfo group, the copolymer having a weight average molecular weight determined by gel permeation chromatography of 2,000 to 100,000, wherein at least one of R1 and R2 is a fluoroalkyl group having 1 to 4 carbon atoms and R3 in the formula (2) represents a fluoroalkyl group having 1 to 20 carbon atoms.
