摘要:
In a circumstance in which light is emitted from many electronic flashes, e.g., a press conference hall or a wedding hall, light emission from other electronic flashes overlaps preliminary light emission performed before main light emission. This decreases the photometry accuracy with respect to preliminary light emission and makes it difficult to perform proper flash exposure. In a camera system designed to perform preliminary light emission before main light emission, photometry is performed a plurality of number of times upon preliminary light emission, and flash exposure is performed by suppressing photometric values which may have been influenced by light emission as disturbance other than the preliminary light emission.

Provided is a process for preparing an immobilized enzyme, which comprises the steps of immobilizing an enzyme used for decomposing oil & fat on a carrier, by adsorption, without drying, bringing the immobilized enzyme into contact with a fatty acid triglyceride or fatty acid partial glyceride, or mixtures thereof, and adjusting the moisture content of the enzyme to 5% to 50% by weight based on the weight of the carrier, wherein the enzyme is used for esterification.

A process for producing diglycerides is provided by which high-purity diglycerides can be produced at a lower cost and more efficiently than conventional esterification and glycerolysis processes, and which inhibits the deterioration of oil quality, such as discoloration, and the loss of trace active ingredients derived from a feedstock of fats and oils, which involves partially hydrolyzing a fat or oil, followed by esterifying the resultant product with glycerol.

A small-sized electric mechanical transducer wherein plates are disposed to surround a bobbin in association with yokes. Magnetic passages are formed among the plates. Each of a pair of magnets drives the bobbin in accordance with the electric signals input into the driving coil. Also, an optical type pickup apparatus positively capable of the signal reading operation in which the lens holder is not out of shape even if the lens holder is driven in the focusing direction and the tracking direction, because the gravity center of the lens holder is conformed to the action point of the resultant force of the forces to be produced by the control signals to be input into the driving coil, and by the magnetic field of the magnetic circuit.

A rotary table unit having a stationary base element and a table element rotatably mounted on the stationary base element is provided with hydrostatic and hydrodynamic bearing guides forming a composite bearing guide mechanism for enabling smooth and stable rotation of the table element under application of local load to the table element. The rotary table unit is also provided with a main drive motor for rotating the table element and an auxiliary drive motor for supplementing a drive force of the main drive motor in response to a change in load applied to the table element.

A display device in the finder of a camera has a plurality of digits of light-emitting elements for displaying exposure information on the side of a frame of field of view of the finder. The light-emitting element of the nearest one of the digits to the frame of field of view is made brightest, and, as the distance from the frame increases, the brightness of the light-emitting element of each digit is made lower. Therefore, the apparent brightnesses of all the light-emitting elements become almost equal to one another, permitting the observer to read the displayed information with ease and clearness.

One end of a casing in which a rotating shaft is supported by a floating metal bush is extended to surround the outer periphery of an oil thrower formed adjacent to an end of the shaft so that an oil-thrower space is defined by the shaft, the oil thrower, the casing and the floating metal bush, and an arcuate opening is formed through the wall of the casing so that the lubricating oil trapped in the oil-thrower space is discharged through this opening to an oil outlet.

A motor drive camera incorporates a motor drive device and a power source for the device and is adapted to mount a detachable auxiliary power source device to supply additional electric power to the motor drive device so as to raise the film winding up speed. The motor drive device includes a timer device whose operation is initiated at the same time as the initiation of power to the motor drive device and which effects the stop of power to the motor after the passage of a predetermined time. The operating time of the timer device is adapted to be changed in order to prevent the film from being damaged when mounting the auxiliary power source device to the camera.
摘要:
An electromagnetic device adapted to operate with a battery of small capacity and having an armature arranged to move upon energization and de-energization of a coil, to and away from a yoke respectively. In order to insure that, after having been attracted, the armature is in intimate contact with the yoke over the entire prescribed area of interface therebetween, there is provided an annular elastic spacer which may be of round cross-section secured in an annular recess around a pivot pin for the armature at the center of length thereof and fitted in a vertical hole of the armature to permit not only absorption of the shock on the armature, thus protecting the attraction face, but also tilting movement of the armature about the spacer ring with respect to the yoke.
