Abstract: The apparatus of the present invention is provided with flashing means (11) for effecting preliminary flashing and main flashing, split photometry means (13) for metering reflected light from the area of the object field divided into a plurality of areas and putting out a photometric output for each of these areas, preliminary flashing control means, calculation means and main flashing control means. The preliminary flashing control means causes the flashing means to effect preliminary flashing prior to main flashing, and when in that case, at least one of the photometric outputs from the split photometry means reaches a predetermined value, causes the flashing means to repeat the preliminary flashing while decreasing the quantity of emitted light thereof, and when the photometric outputs become null before the predetermined value is reached, causes the flashing means to stop the preliminary flashing. The calculation means determines the divided areas which are not used for the flash limiting during the main flashing by the use of the photometric outputs and the quantity of emitted light during preliminary flashing at the last stage. The main flashing control means controls the main flashing of the flashing means on the basis of the output of the calculation means.

Abstract: A portable scanning head emits and receives light from a light-emitting diode to read symbols, such as bar-code symbols. The optics within the scanner are operative for focusing a light beam and the view of a light sensor in different planes exteriorly of a scanner housing. Imaging means are provided in the unit for imaging a viewing window. The viewing window has an area smaller than that of the scan spot. The system can employ an LED as a light source and tolerate the relatively large-sized (on the order of millimeters) scan spot without sacrificing reading performance since the photodiode "sees" only that portion of the scan spot visible through the viewing window.

Abstract: The invention relates to a flying body which can be used as a toy. This flying body consists essentially of an approximately circular disc and a wing adjoining it on one side with a cross-section which is approximately symmetrical relative to its centre plane and with a thickening on one side or in the centre. The centre of gravity of the flying body lies on one side of the axis relative to its longitudinal mid-axis and on the side of the disc relative to its transverse mid-axis. It is achieved, in particular, by this distribution of the centre of gravity that the flying body assumes a hovering position after being thrown or slung in the air and, whilst rotating around the disc, slowly drops to the ground. The flying body can thus also be used in confined spaces. The disc can be constructed as an annular part or as a closed body. To avoid injuries, the flying body consists of a light, resilient material.

Abstract: An apparatus and a method for creating a database wherein the data entry, such as a journal entry in accounting, is the canonical record can be implemented utilizing a microcomputer. A plurality of data entries to be classified are separate records each comprised of one or more items having associated quantities and an entry number serving as a pointer to the record. Each item contains information including at least an item number or label and a quantity. At least two item indicators are then generated for each of the item numbers. A mapping function is applied to each data entry to assign the item indicators for the item numbers based upon the associated quantities. The item indicators for the data entry are sorted into ascending numerical sequence and an n-dimension sparse matrix is selected where "n" is the number of items in the data entry. If the present combination of item indicators is new, a design record is created for the database based upon the sparse matrix and including the item indicators, the associated quantity sums, the total number of data entries summarized in the design record and a pointer (a chain of entry numbers) to the records of the data entry detail. The quantities for the present data entry are added to the quantity sums and the entry number is stored in the pointer chain. After all the data entries have been processed, a search routine can be utilized to review the various design records as desired.

Abstract: A first image signal for a screen wider than that obtained by a TV signal of an existing television system is converted to a multiplexed signal that can be reproduced with a receiver of the existing television system, and input to a selector (203). The selector (203) divides the input signal into a center portion signal and upper and lower black bar portions signals of the screen. The multiplexed signal has a center portion signal as an image display portion and upper and lower black bar portion signals as non-image portions. A difference signal (first LD signal) is multiplexed on the upper and lower black bar portion signals. A rearranging unit (22), a 5-time expander (223), a double speed converter (224), a delay unit (225), and a selector (226) reproduce the first LD signal from the upper and lower black bar portion signals. A delay unit (204) and a double speed converter (205) double-speed convert the center portion signal. A line interpolator (206) and a selector (208) generate a progressive scanning signal. A 5 → 6 converter (219) expands the progressive scanning signal in the vertical direction. The first LD signal is added to the interpolated scanning line of the first field by an adder (207). An LD generator (209) generates a second LD signal from the compensated progressive scanning signal in the same manner as on the transmission side. A line interpolator (212) and a selector (241) also generate a progressive scanning signal. The second LD signal is added to the interpolated scanning line of the second field by an adder (213).

Abstract: A method for recording information data in a recording region of an optical disc includes subdividing the recording region of the optical disc into plural recording zones each having 2 n  tracks,  n  being a natural number, and recording the information data so that the recording capacity per track is equal in one and the same recording zone and the recording capacity per track is different while the line recording density in each recording zone is approximately equal in different recording zones and the line recording density in the tracks of the inner most recording zone is rendered substantially equal to the line recording density in the tracks of the outer most recording zone. High-speed accessing may be achieved easily and the recording capacity per side may be increased significantly. The number of recording zones may be increased optionally for increasing the degree of freedom. By changing over the recording zones by a number equal to a power of 2 of the number of tracks, the recording zones may be changed over easily by using only several upper order bits of a digital discriminating signal if such discriminating signal is used. 
     By recording information data on the optical disc in accordance with a magnetic field modulating system, a mark length recording and an edge recording system, a larger quantity of data may be recorded and/or reproduced stably and accurately without producing jitter.
