摘要:
An eye refractive power measurement apparatus for objectively measuring eye refractive power of a patient's eye, includes: a light-projecting optical system that includes a light source and projects measurement light onto a fundus of the patient's eye; a light-receiving optical system that includes an imager device serving as a two-dimensional light-receiving element and receives the measurement light reflected from the fundus; and an operating section that determines the eye refractive power of the eye based on a two-dimensional pattern image by the measurement light imaged by the imager device. The light source is a super-luminescent diode or a laser diode that emits light having a center wavelength in a range of approximately 850 nm to 940 nm.

Disclosed is an aperture variable inspection optical system including a variable aperture unit 13 having a polygonal light transparent section and light collecting systems 12a, 12b for forming an irradiation spot U of light passing through the variable aperture unit 13 at the position of a sample S. The variable aperture unit 13 is capable of changing the shape/size of the polygon. The size of the irradiation spot U can be changed without rearranging the aperture unit.

A method for manufacturing a polishing pad prevents slurry leaks and provides a pad that can be used to provide high optical detection accuracy. The method for manufacturing a polishing pad includes forming a groove for injecting a light-transmitting region forming material on the back surface of a polishing layer; injecting the light-transmitting region forming material into the groove and curing the material to form a light-transmitting region; and buffing the front surface of the polishing layer to expose the light-transmitting region on the front surface.

This invention constructs within the LAN a private area network (PAN) which is configured by terminal devices (personal computers and the like) of a specific group, is hardly influenced by the LAN traffic, and has high security. For this purpose, a PAN server which manages the communication route between specific terminals is installed within the LAN. The PAN server sets the communication route of each terminal device as label information, and causes switches and terminals to set pieces of label information generated for them. When the frame of data from a given port of each connection switch contains information representing PAN communication, the connection switch outputs the data to only a port specified by routing label information described in the frame.
摘要:
In a video signal processing apparatus for generating a video signal in a prescribed format by capturing output of a solid-state imaging element that is driven by corresponding to each timing of horizontal scanning and vertical scanning, a first signal processing circuit generates a first video signal by performing the first signal processing on an analog video signal that is continuously outputted from the solid-state imaging element by a horizontal-line unit. An A/D converter circuit generates the first video data by converting the first video signal to digital information. A memory circuit stores the first video data at least by one horizontal-line unit, and reads out the first video data with a delay of a prescribed delay period. A second signal processing circuit generates the second video data by performing the second signal processing on the first video data that is read out from the memory circuit.

摘要:
A vehicular seat device assumes, as seat arrangements, a seating state and in which an occupant can sit, an entry/exit state in which the seat cushion (12) is in a standing state, and a retracted state in which a seatback (14) is superimposed on an upper side of the seat cushion (12). The vehicular seat device has a first linking member (21), a second linking member (22) and a drive mechanism (16) that are capable of changing the posture of the seat cushion (12) synchronously with the tilting of the seatback (14). Since the seat arrangement is changed synchronously with the tilting of the seatback (14), it is possible to reduce the burden of operation on an occupant in changing the seat arrangement, while allowing various seat arrangements.

A method of producing a liquid crystal emulsion composition which has a viscosity of 30,000 mPa·sec or more at a 2-hold dilution and an improved stability, includes admixing a hydrophilic surfactant which is a polyoxyethylene polyoxypropylene alkyl ether having an HLB of 10 to 20 with a hydrophilic surfactant having an HLB of 13 or more which is comprised of a polyoxyethylene fatty acid derivative; admixing the resulting admixture with a mixture of 5 to 10 parts by weight of the thus combined surfactants with 5 to 30 parts by weight of an oil component; admixing the resulting admixture with a mixture of 40 to 80 parts by weight of a water-soluble polyvalent alcohol and 8 to 40 parts by weight of water; and heating, homogeneously mixing and then cooling the thus obtained admixture.
摘要:
A method for manufacturing a polishing pad, which may be laminated, with a small number of manufacturing steps, high productivity and no peeling between a polishing layer and a cushion layer includes preparing a cell-dispersed urethane composition by a mechanical foaming method; continuously discharging the cell-dispersed urethane composition onto a face material, while feeding the face material; laminating another face material on the cell-dispersed urethane composition; curing the cell-dispersed urethane composition, while controlling its thickness to be uniform, so that a polishing layer including a polyurethane foam is formed; cutting the polishing layer parallel to the face into two pieces so that two long polishing layers each including the polishing layer and the face material are simultaneously formed; and cutting the long polishing layers to produce the polishing pad.
摘要:
The main surface of a quartz component is divided by an offset into a first region having a larger height around an inner perimeter and a second region adjacent to the outer perimeter of the first region. Repeated restoration of a damaged component by forming a bulge on the first region and machining the bulge to make a flat surface while maintaining the offset enables long term use of the component.

An organic semiconductor device includes a organic semiconductor layer with carrier mobility formed between a pair of opposing electrodes. The device also includes a buffer layer that is inserted between at least one of the pair of electrodes and the organic semiconductor layer in contact therewith. The buffer layer has a value of a work function or an ionization potential between a value of a work function of the electrode in contact and a value of an ionization potential of the organic semiconductor layer.
