摘要:
A combinational weighing system with a plurality of article batch handling means has an article feeding means for feeding articles to be weighed into the individual article batch handling means, and after a desired combination or weights within a preselected range is determined by a computer, the article batches from the selected article batch handling means are discharged together to be made into a package. The system also includes a means for measuring the weight of the article accumulated on the article feeding means and the output signal from such a weight-measuring means is transmitted to control the operation of a conveyor for supplying the articles to the article feeding means.
摘要:
An auto-focus camera including an automatic rangefinder device for generating a distance signal indicative of the distance between the camera and a target object to be photographed, a timer circuit for generating an output signal a predetermined time after a power switch is closed, to place a lens drive mechanism in an operative condition for repositioning an objective lens assembly of the camera in search of the true focus setting, and a lens arresting circuit including electromagnetic units. Either of the electromagnetic units is operable to arrest the objective lens assembly at a corresponding focal position when energized by the distance signal. The automatic rangefinder device can measure the distance from the camera to the target object independent of the release of the lens drive mechanism.

Information setting apparatus for a camera comprises pulse generating circuitry, pulse counting circuitry and apparatus for visually displaying variable digital information represented by the pulse count in the pulse counting circuitry. The digital information displayed is changed by altering the pulse count stored in the counting circuitry. A manually operable switch stops the pulse input to the counting circuitry to fix the digital information displayed by the display apparatus in accordance with the desired setting. Apparatus is provided for projecting an image of the displayed information onto the camera film. In cameras provided with a viewfinder, the image of the displayed information is projected into the viewfinder field of view.
摘要:
An exposure control device for a photographic camera uses a conventional exchangeable lens and achieves a highly accurate exposure control commensurate with a pre-selected shutter speed by a light measuring device measuring scene light transmitted through the objective lens, diaphragm, and exchangeable lens. The device also permits exposure control commensurate with a pre-adjusted diaphragm aperture by storing the output from the light measuring device determined with the adjusted diaphragm aperture to control the shutter speed. However, when the device controls the exposure with a pre-selected shutter speed, the output from the light measuring device produced with a fully open diaphragm aperture is compared with the output produced commensurate with the pre-selected shutter speed to thereby control the diaphragm aperture in shifting from its open position to its closed position, and then stores the output from the light measuring device with the adjusted diaphragm aperture to thereby control the shutter speed.
摘要:
In an exposure control device for a photographic camera a shutter speed control signal generating circuit measures scene light transmitted through an objective lens and a diaphragm for automatically controlling the shutter speed commensurate to the measured light output. A control output signal is generated in response to a manually selectable shutter speed. A diaphragm control device controls the diaphragm aperture according to the difference in the light measuring output and shutter speed output signal. The light measuring and shutter speed output signals are selectively connectable to a shutter speed control device for exposure control. A portion of the automatic shutter speed control signal is added to the manually selected shutter speed control signal so that diaphragm aperture control is effected according to the difference between the combined signal and the automatic shutter speed control signal. Control of the diaphragm and shutter speed as well as programmed exposure control of the shutter speed and diaphragm aperture commensurate with the brightness of an object are effected.

A method for designing a heat-resistant mutant enzyme, the method including the step of reducing a distance between the α4 helix and the α6 helix in a protein three-dimensional structure to become smaller than that of a wild type enzyme through deletion, replacement, addition, or insertion of one or several amino acids in the amino acid sequence of the wild type enzyme with respect to tyrosine-dependent short-chain dehydrogenase/reductase.

Provided is a thin three-dimensional interactive display which enables multi-touch sensing and three-dimensional gesture recognition. The three-dimensional interactive display includes a light source for irradiating an object to be detected with a light, a light modulation layer, into which a scattered light generated by irradiating the object with the light from the light source enters, at least for modulating an intensity of the scattered light, a transparent light-receiving layer for receiving the light transmitted through the light modulation layer, and a display panel or a back light panel disposed on the opposite side of the transparent light-receiving layer from the light modulation layer. The transparent light-receiving layer has a two-dimensional array of light-receiving elements.

摘要:
A non-wetted all solid protein photoelectric conversion device that is able to be operated without existence of a liquid such as water inside and outside of the device and a method of manufacturing the same are provided. The non-wetted all solid protein photoelectric conversion device has a structure in which a solid protein layer composed of an electron transfer protein is sandwiched between an electrode and an electrode. The solid protein layer is immobilized onto the electrodes and. The solid protein layer does not contain a liquid such as water. The solid protein layer is composed of a monomolecular film or a multimolecular film of the electron transfer protein.
