Abstract: In the endoscope, in which a protective tube and a linear transmission member are arranged from a tip end portion to an operating unit, for transmitting rotation of a motor to the tip end portion through the linear transmission member to thereby drive a movable lens for making the observation distance variable, the protective tube is divided into a front-side tube and a rear-side tube having a larger inner diameter than the front-side tube, and these are connected together within the operating unit. Also, the linear transmission member is also divided into a front-side transmission member and a rear-side transmission member having a larger outside diameter, and as regards this rear-side transmission member, there is used a multiple coiled spring formed by winding strands of a predetermined number of threads brought into tight contact in a state, in which space for predetermined intervals is left.

Abstract: A surface roughness distribution in the surface of a silicon epitaxial wafer is made uniform by optimizing a temperature distribution in the surface of a susceptor used in a vapor phase thin film growth apparatus. The susceptor is not supported by its center of the rear surface thereof, but only the peripheral portion thereof is supported using vertical pins respectively provided at the far ends of spokes radially branched from a rotary shaft. The susceptor is constituted so that a difference in temperature between the maximum and minimum in the surface of a silicon wafer is suppressed to a value equal to or less than 7° C. Hence, a surface roughness distribution in the surface of the silicon epitaxial wafer can be suppressed to a value equal to or less than 0.02 ppm.

Abstract: An ultraviolet light permeable filter for an ultraviolet detection light is equipped on a filter glass surface with a dielectric multi-film layer which allows a visible radiation of wave length from 694 nm to 780 nm to reflect on the layer. The 694 nm to 780 nm wave length does not penetrate through the multi-film layer. When placed in an ultraviolet detection system, this filter prevents the occurrence of a reddish halation during inspection and display of a flaw detection light.

Abstract: The present invention provides a system for endoscopes which can supply air and water according to each application by regulating air and water flow rates independently. Although air and water may be supplied with one pump, the present invention controls air and water flow rates separately by using an air supply pump and water supply pump and by controlling a plurality of open-close valves installed, for example, on atmospheric escape pipes. The air channel and water channel are connected, for draining, by a first connecting pipe. If the air supply pump is used also for water supply and the water supply pump is used also for air supply, it is possible to supply air and water at a high flow rate fast enough even for high-speed water injection. If a fixed flow rate is used for a specified time at the start, specific operations can be simplified.

Abstract: An under voltage lockout {overscore (RESET)} circuit is connected to the {overscore (RESET)} terminal of a EEPROM. The EEPROM is used in a system which may include a computer or processor and which may be used in space. The under voltage lockout {overscore (RESET)} circuit maybe an under voltage lockout circuit used on a LinFinity SG1526/B or a Unitrode UC1526 regulating pulse width modulator which maintain the {overscore (RESET)} voltage low at all values of power supply voltage source voltage less than a predetermined level. In one embodiment the under voltage lockout {overscore (RESET)} circuit output voltage does not have a “floating voltage” which rises to a level higher than its value when a comparator initially senses that a power supply voltage source voltage is less than the predetermined amount. This is a flat {overscore (RESET)} characteristic under voltage lockout.

Abstract: A double-wavelength aperture restricting filter has a zonal part adapted to act such that one wavelength &lgr;1 of light keeps the quantity of light in an outer peripheral part of the luminous flux thereof whereas the other wavelength &lgr;2 of light apparently extinguishes this quantity of light by an interference effect. The zonal part has such a step that light supposed to pass a position corresponding to the zonal part if the zonal part does not exist and light passing a position at which the zonal part is formed if the zonal part exists generate therebetween a phase difference satisfying predetermined conditional expressions, whereas the circle formed by a step boundary has a diameter residing between two luminous flux diameters desired in two systems used for the wavelengths &lgr;1 and &lgr;2, respectively.

Abstract: One surface of the substrate constituting a diffraction type lens is formed with a zone plate exhibiting a smaller converging action with respect to a first wavelength &lgr;1 of light and a greater converging action with respect to a second wavelength &lgr;2 of light, whereas the other surface is formed with a zone plate exhibiting a smaller converging action with respect to the second wavelength &lgr;2 of light and a greater converging action with respect to the first wavelength &lgr;1 of light.

Abstract: One surface of an objective lens is provided with a zonal part which acts such that the quantity of light having a wavelength of &lgr;1 is apparently canceled in the outer peripheral portion of the luminous flux due to an interference effect, whereas the quantity of light having a wavelength of &lgr;2 in the outer peripheral part is kept as it is. The zonal part has such a step that light supposed to pass a position corresponding to the zonal part if the zonal part does not exist and light passing a position at which the zonal part is formed if the zonal part exists generate therebetween a phase difference satisfying a predetermined conditional expression. The numerical aperture at a boundary position of the step has a value between two numerical apertures for the respective wavelengths &lgr;1 and &lgr;2.

Abstract: There is provided a light shielding plate to shield light from a light source lamp, and this light shielding plate is rotated and driven by a light shielding plate drive circuit, and a charge stored in a CCD for a period of, for example, 20H at a start of an effective period J of a vertical scanning period, is discharged and this is set as a non-operating period and a drive control over the light shielding plate for a period of 40.5H which is a sum of this non-operating period and a blanking period B (20.5H) is performed. This provides an adequate margin of time for controlling the light shielding plate at starting and stopping times and makes the drive control easier.

Abstract: In a TV camera main body, a still-image-luminous-flux-decomposing prism is disposed adjacent to a color-decomposing prism of a TV-image-capturing system, whereby still images whose aberration is favorably corrected as with TV images are obtained in a simple and compact configuration. A mechanical shutter is disposed in an optical path of the still-image-capturing system, so as to prevent image blurring and smear from occurring due to temporal shifts between field images. A four-block color-decomposing prism 11A, in which each glass prism has a form identical to a color-decomposing prism of a dual green type, is constituted by a still-image-capturing prism 2d, and a TV-image-capturing three-color-decomposing prism system comprising a prism for blue 2a, a prism for red 2b, and a prism for green 2c. A mechanical shutter 34 is disposed between the light exit end face 7d of the still-image-capturing prism 2d and its cover glass 6d.
