摘要： In an electronic flash device, wherein electrical energy stored by a main capacitor and an electronic flash tube is fired by the stored energy, a relaxation oscillator is adapted to oscillate when the main capacitor is charged to a given voltage level, which is a condition for completion of preparation for flash tube operation. The relaxation oscillator includes a capacitor, a glow discharge tube, and a resistor and the oscillation thereof causes intermittent glow discharge through the glow discharge tube for indicating the completion of preparation for flash tube operation. The electronic flash tube is triggered to emit a light flash by the stored energy of the relaxation oscillator capacitor. Excitation of the flash device, even with a power supply switch open, is prevented by isolating the main capacitor from the trigger capacitor and also from the glow discharge tube to also prevent an indication of flash preparation. The trigger capacitor is also discharged through the resistor to prevent actuation of the flash device should the flash synchro switch be closed with the power supply switch open.

摘要： An object of one embodiment of the present invention is to provide a polishing slurry which can reduce dishing and erosion of a to-be-polished semiconductor wafer. The polishing slurry contains an oxidizing agent and two or more kinds of abrasive grains for polishing, i.e., fumed silica and colloidal silica. A ratio (selectivity ratio) between a polishing rate of a metal film such as a tungsten film and a polishing rate of an insulating film (oxide film) such as a SiO2 film can be adjusted by changing a mixing ratio between fumed silica and colloidal silica, and dishing and erosion of the semiconductor wafer can be thus reduced.

摘要： In a camera provided with a data or auxiliary information recording device and an electronic flash device for illuminating an object scene to be photographed, another electronic flash device is provided for the illumination of data to be recorded. A single power source is used for both the above two electronic flash devices and an automatic exposure control circuit. To avoid a voltage drop of the power source during the operation of the exposure control circuit due to charging of the main capacitor for the electronic flash for the scene illumination, a power supply switch for the main capacitor charging circuit is manually closed independently of the camera exposure operation. A capacitor for energizing the electronic flash for the data illumination is charged in conjunction with the camera release operation before the camera exposure is commenced.

摘要： In a telescope, the adjustment order is limited so that dioptric power adjustment is made after adjustment of a distance between a pair of optical systems is completed. A pupil distance and a dioptric power correction amount are stored in a memory for every user. When a user uses the telescope, his or her pupil distance and dioptric power correction amount are read out from the memory to automatically make adjustment.

摘要： In a telescope according to the present invention, defocus amount of an optical system constituting the telescope is calculated; whether or not the defocus amount is within a predetermined in-focus range obtained from a focal point adjusting ability of human eye is discriminated; and when the defocus amount exceeds the in-focus range as a result of the above discrimination, the optical system is driven. The optical system is driven in a shorter time than a time required for removing a defocus by human eye.

摘要： A semiconductor switching element is connected in series with a flash tube to stop emission of flash light therefrom during operation of the flash tube. A first and a second integrating circuit are parallelly arranged to be connected either alternatively, or both together, with the switching element. The first integrating circuit integrates photo-current generated by a photocell receiving light from an object illuminated by the flash light, and the second integrating circuit integrates current that is manually adjustable. When both integrating circuits are connected with the switching element, the switching element is turned off by that integrating circuit which first reaches a predetermined trigger level.

摘要： Periodical sterilization is usually needed in the ultrapure water line provided in an ultrapure water-producing system or plant to kill some occasionally occurring viable cells of microorganisms in the ultrapure water as produced or being produced and thereby keep the ultrapure water under germ-free conditions. Now, it is discovered that an aqueous solution containing 1 to 100 ppm of hydrofluoric acid is effective to sterilize the ultrapure water line and is advantageous over the conventional sterilization agents such as aqueous hydrogen peroxide and sodium hypochlorite which were employed normally for the sterilization of the ultrapure water line.

摘要： A new process step for purifying water from a small amount, particularly a last trace amount, of organic impurities included in total organic carbon (TOC) content is incorporated into known processes for the preparation of ultra pure water comprising one or more previous filtration steps and a series of purification steps known per se. The new step comprises irradiating the water to be treated with a light in the presence of a photocatalyst comprising an inorganic semiconductor selected from TiO.sub.2, SrTiO.sub.3 and CdS in fine particulate form and a noble metal and/or an oxide thereof selected from Pt, Pd, Ru, RuO.sub.2 and Rh deposited on said semiconductor particles for a period of time sufficient to oxidatively decompose the organic impurities, resulting in a decrease in TOC content of the water to a level lower than the minimum detection level of TOC detectors, typically

摘要： An automatic electronic flash device for use with a camera includes a flash tube carried by a housing. A battery is carried by the housing as a source of electric supply. A capacitor is connected to the flash tube to fire it when discharged. A circuit is used to automatically adjust the amount of light emitted from said flash tube upon the firing of the tube. The circuit includes a light receiving element arranged to receive light reflected from a photographic object upon the firing of the tube. The information of distance from the camera to an object to be photographed is fed to the circuit as a function of the amount of light received. A switch is connected to the circuit to cause it to vary the amount of light emitted from the flash tube. A calculator enables calculation of a plurality of combinations of aperture settings and distance setting in response to a film speed setting, so that selection of a desired film speed will result in indication of a desired aperture setting and distance setting. Light emitting diodes are disposed adjacent to the calculator for indication of one of the combinations calculated by the calculator. Another switch connects one of the light emitting diodes to the battery for selective energization thereof in association with the switching of the above switch connected to the circuit.
