摘要:
16-membered macrolide compounds wherein both of hydroxyl groups at the 3"- and 4"-positions form ether bonds together with two alkyl groups which are either the same or different from each other is useful as an antibacterial agent. The macrolide compounds represented by formula (I) are prepared by chemically modifying midecamycin A.sub.3 to obtain a synthesis intermediate of the formula (II), which is further chemically modified. ##STR1##
摘要:
A display panel driver has two driver circuits that drive separate halves of a display panel. Each driver circuit occupies a separate integrated circuit chip. The driver has a screen saving mode in which each driver circuit displays an independent screen saving image that moves in synchronization with a timing signal. The timing signal is generated in one driver circuit and transmitted by a chip-to-chip interface to the other driver circuit. The two screen saving images are thereby coordinated to create what appears to be a single screen saving display.

The present invention provides a method of transporting parts constituting a product in a product assembly plant, the method including placing the parts in a returnable container, the returnable container being carried by a worker within the plant, wherein the returnable container is formed by expansion molding of expanded particles of a polyolefin-based resin, the relationship between the weight and volume of the returnable container satisfies Formula (1) below, and the relationship between the flexural modulus and density of the returnable container satisfies Formula (2) below: 650≦(a−W)/W×V≦4,000 (1) (where W is the weight (kg) of the returnable container, V is the volume (L) of the returnable container, and a represents 23 kg, i.e., the maximum weight that can be carried by a worker within the plant, which is recommended by the National Institute for Occupational Safety & Health (NIOSH)); 0.10≦F/D≦0.60 (2) (where D is the density (g/L) of the returnable container, and F is the flexural modulus (MPa) measured according to ISO 1209).
摘要:
A color balancing circuit for a flat panel display such as an electroluminescent display generates a primary current that can be varied to adjust the overall brightness of the display. Three currents related to the primary current by selectable ratios are generated, by current mirror circuits, for example; the ratios can be individually varied to adjust the color balance. Driving currents are generated from the three adjusted currents, by mirroring the adjusted currents, for example, and are used to drive display elements that emit light in the three primary colors. Image brightness and color balance can accordingly be adjusted separately, even though both are adjusted by adjusting the driving current. Circuit size is reduced in that the same primary current is used for all three primary colors.
摘要:
A driving circuit drives a display panel having a matrix of picture elements and electrodes. The driving circuit includes a memory storing compensation data for compensating for position-dependent brightness differences between the picture elements. The brightness differences are due to the stray resistance and capacitance of the picture elements and electrodes. A correction circuit modifies image data according to the compensation data to generate control signals, which are used to control drivers that drive the picture elements via the electrodes. The modified image data produce a display with an even average brightness over the entire display panel.

Disclosed is a drive circuit for a panel display device for driving light-emitting devices arranged at respective intersections between a plurality of data lines and a plurality of scan lines. This drive circuit includes a voltage control circuit for charging the light-emitting devices to a voltage necessary for light emission by connecting the data lines to a predetermined power supply potential in a rising period prior to a period for selectively causing the light-emitting devices to emit light; and a drive control circuit for selectively connecting the data lines to a constant current source after the rising period.

The object of the invention is elimination of an occurrence of instantaneous light in the center part of a display, a border between the upper half and the lower half of the display. An scanning method of the display, dividing the display panel to a first filed and a second filed, starts a counter therein, synchronized with the timing of driving a first row electrode of the first filed thereof, and drives a first row electrode of the second filed thereof, every time the counter value changes.

摘要:
A method of manufacturing an incandescent lamp which has a tube extending through the pinch seal of the glass envelope both for evacuating the same and for subsequently introducing a halogen gas therein. An envelope blank has its open end portion heated prior to pinch sealing, with a filament mount assembly inserted therein but with the gas exhaust/supply tube not inserted to preclude the possibility of its clogging. Only after the open end portion of the envelope blank has been heated to a viscid state is the gas exhaust/supply tube inserted therein. The envelope blank is pinch sealed immediately thereafter.
