摘要:
A watertight connector includes male and female housings (10, 20). The male housing (10) has an engaging end surface (10A) with a mounting recess (15) in which a seal (40) is mountable. The seal (40) has sealing portions (45) to be fitted around outer surfaces of pillars (16) that surround male terminal fittings (13). A lattice-shaped array of press-in grooves (46) is provided between the sealing portions (45), and a peripheral press-in groove (47) is formed between the sealing portions (45) and the mounting recess (15). A peripheral rib (32) and a lattice-shaped array of ribs (33) project from an engaging end surface (20A) of the female housing (20). The ribs (32, 33) enter the press-in grooves (46, 47) as the housings (10, 20) are connected and come into sealing contact with the outer circumferential surfaces of the sealing portions (45).
摘要:
An exposure apparatus having an illumination light source and a stage for an exposed object to be mounted thereon, in which at least one of an illumination optical system and a projection optical system includes a plurality of optical articles in each of which a first optically transparent thin layer and a second optically transparent thin layer having a higher refractive index than that of the first optically transparent thin layer are laminated on a surface of a substrate. At least one of the first and second optically transparent thin layers includes a layer of oxides or fluorides and atoms of at least one selected from the group consisting of krypton, xenon and radon, in which the content of the atoms is within a range of from 0.5 atomic ppm to 1 atomic %, inclusive.
摘要:
A connector is provided for production by a mold having a simple configuration. Inner surfaces of opposite side walls of a cavity (11) of the connector housing (10) are formed with guiding grooves (16) for permitting the passage of restricting projections (24) when a properly oriented female terminal fitting (20) is inserted. In the outer surfaces of the opposite side walls of the connector housing (10) are formed guide grooves (18) for permitting the passage of engaging projections (42) of a retainer (40). Through holes (17) are so formed in the side walls of the connector housing (10) as to provide partial communication between the guiding grooves (16) and the guide grooves (18).
摘要:
Four sets of shower heads 100, 200, 300, 400 are located in a surface modifying chamber of a surface modifying apparatus, and each shower head 100, 200, 300, 400 has surface modifier piping including a plurality of spray nozzles. The nozzles are arranged such that showers of an aqueous ozone solution injected from every adjacent two nozzles will contact the resin molded product and partly overlap one another. The phases in position of the nozzles can be offset a half-pitch or staggered with the staggered arrangement of the nozzles serving to compensate for any insufficient oxidation reaction to achieve uniform surface modification over the entire surface of the resin molded product 2. Further, the time required for the surface modification treatment can be reduced.
摘要:
Disclosed is an image pick-up device which uses a charge transfer type solid state image pick-up device, and further is provided with a shutter so as to form a high quality picture signal in such a manner that the smear is prevented by prohibiting the incidence of the light on the device while the charge is transferred in the device. Further, the device is driven by a clock signal for still photographing in order to obtain a high quality picture information for one frame surely. Further, the photographing parameter is automatically changed over or the monitor is changed over between the motion picture photographing mode and the still photographing mode.
摘要:
In a photoelectric converting apparatus having a plurality of photosensors divided into an opening portion and a light shielding portion, a carrier eliminating structure to block the inflow of photosignals from the opening portion is provided between the photosensor in the light shielding portion and the photosensors in the opening portion. The photosensor comprises of a photoelectric converting transistor having a control electrode region to accumulate the carriers generated by the light excitation. The carrier eliminating structure has the same constitution as that of the photosensor. The potential of the control electrode region is fixed to a constant potential so as to attract the carriers from the opening portion.
摘要:
In an optical operation apparatus, a light source emits a light intensity-modulated on the basis of a first electrical signal. A modulating device receives the light from the light source and intensity-modulates the light on the basis of the first signal, and a photoelectric converting device converts the light modulated by the modulating device into a second electrical signal. These functions are carried out by any of a number of different arrangements of filter elements, and electro-optical or acoustico-optical devices can be used for intensity modulation.

A radiation sensing device includes radiation sensor for generating an electrical indication indicative of the distribution pattern of received radiation, a storing device for storing the electrical indication generated by the sensor, and a read-out device for reading out the stored electrical indication from the storing device. The sensor includes a first plurality of sensing elements, while the storing device includes a second plurality of storage elements. The second plurality is fewer than the first plurality.
摘要:
There is disclosed a solid-state color imaging apparatus which comprises an imaging device composed of a solid-state charge-coupled device having a plurality of cells each of which has at least two potential wells and color filter having a combination of color filter elements which are positioned corresponding to the two potential wells in such a manner as to provide different spectral sensitivities to the two potential wells.
