Abstract: PURPOSE:To prevent the operation of a developer layer thickness regulating member caused by the sticking of toner from being obstructed by positioning the contact with a feed roller and the developer layer thickness regulating member at a region higher than the shaft center of a developing roller and inside housing. CONSTITUTION:The developing roller 13 arranged to face oppositely a photosensitive body is rotatively attached to opening formed on the housing 12, the developer layer thickness regulating member 15 arranged on the edge part of the opening is pressed and held on the periphery of the developing roller 13, and the feed roller 16 rotatively and pivotally supported inside the housing is abutted on the developing roller 13. The contact of the feed roller 16 and the developer layer thickness regulating member 15 with respect to the periphery of the developing roller 13 is positioned at the region higher than the shaft center of the developing roller 13 and inside the housing, so that a place where the periphery of the developing roller 13 rubs on the feed roller and is primarily electrified and a place where the periphery of the developing roller 13 rubs on the developer layer thickness regulating member 15 and is secondary electrified are closed. Thus, the operation of the developer layer thickness regulating member caused by the sticking of the unelectrified toner on the toner stuck by the primary electrification is prevented from being obstructed.

Abstract: PURPOSE:To detect back light correctly by metering light and finding range on time-division basis from the output of a photodetecting element, detecting a short-distance, an intermediate-distance, and a long-distance subject from the range finding information and comparing photometric information, and judging back light when the brightness difference is larger than a specific value. CONSTITUTION:Respective subjects are scanned successively and three signals indicating that the subjects are at long distance, intermediate distance, and short distance are outputted from lines 12-1-12-3 on the basis of input range finding information. Pieces of photometric information on the subject within respective distance ranges are obtained from three amplifiers 21, 23, and 25. A comparator 33 compares the largest photometric value of the subject at the long distance from a back light setting circuit 84 with the photometric value of the intermediate-distance subject and a comparator 36, on the other hand, compares the largest photometric value of the long-distance subject passed through the back light level setting circuit 84 with the photometric value of the short-distance subject. When the intermediate distance and short distance are less than the photometric value, namely, when the subjects are darker, it is judged that the camera is on back light condition.

Title: Timer device
Inventor: UGA KOUZOU
IPC: G04F3/00
Filed: 1978-07-21
Abstract: PURPOSE: To obtain accurate timer operation time by simple circuit constitution, by utilizing signals with comparatively high frequency extracted from a clock circuit of an electronic clock in frequency-dividing shapes.  
     CONSTITUTION: When a switch SW is in ON, signals a set a FF3, and the -Q output is changed into a L level. Output C releases a reset condition of a frequency dividing circuit 2 while being applied to a base of a transistor Tr through a resistance R 1 , and the base is in ON. Thus, currents flow through a relay coil 4 to make a contact piece 4-2, and positive direct current source voltage is applied to load 5. Meanwhile, the circuit 2 starts frequency dividing operation, frequency dividing pulses b in a H level are put out when a fixed time elapses, the FF3 is reset, and the output C is turned into the H level, thus resetting the circuit 2 while bringing the Tr to an OFF condition, then breaking the supply of voltage to the load 5. In this case, accurate timer operation time can be obtained because clock signals in 50Hz are approximate 41 second if the signals are frequency divided by a frequency dividing ratio 1/2 12 .

Title: Composite yarn
Inventor: OKUNO TOKIO
IPC: A41B11/00
Filed: 1998-03-19
Abstract: PROBLEM TO BE SOLVED: To obtain a composite yarn hardly generating the slippage of non- elastic fibers even when squeezed, giving a knitted fabric having a good grade appearance and useful for socks, stockings, etc., by twisting a polytrimethylene terephthalate yarn with an elastic yarn. SOLUTION: This composite yarn is obtained by doubling (twisting) a polytrimethylene terephthalate yarn with an elastic yarn (polyurethane yarn). The obtained composite yarn hardly generates the slippage of the fibers in the longitudinal direction of the yarn and has small irregularity in the yarn. Even when subjected to a tension of about 0.15-0.5 g on the double treatment and to an elongation of about 0.5-3%, the polytrimethylene terephthalate yarn exhibits an elastic recovery of approximately 100%. The composite yarn wherein the polytrimethylene terephthalate yarn is firmly twisted with the elastic yarn is thus produced.
