Filed: 1997-03-17
Abstract: PROBLEM TO BE SOLVED: To reduce an overhead due to a motion vector or the like without deteriorating image quality. SOLUTION: Prediction errors Eg1 (i=1, 2,...N) are calculated by plural mounted prediction methods (step 11). A minimum prediction error Egmin is calculated from the prediction error Eg1 (step 12). A quantization step Q of a coding object small block is calculated (step 13). A permissible range T is calculated from the quantization step Q (step 14). A prediction method that satisfies a relation of Eg1 <=Egmin +T is detected by the prediction errors Eg1 of each prediction method (step 15). A prediction method in which a overhead is smallest among the detected prediction methods is decided as the prediction method for a coding object small block.

Title: Blockage preventive device for selector
Inventor: YAMAMOTO KATSUHIKO
IPC: B07B13/18
Filed: 1997-03-18
Abstract: PROBLEM TO BE SOLVED: To automatically prevent a dust intake port from becoming blocked with dust. SOLUTION: When dust A is not totally sucked through a dust suction aperture 3 with some of it sticking to the aperture 3, an internal pressure above a sucked dust A in the dust suction aperture 3 drops and this pressure drop is detected by a pressure detector 14a, and further, a control device opens an air suction valve 15a and a nozzle ON/OFF valve 18a based on the detection readings. Consequently, an air is sucked into the interior of the dust suction aperture 3 from the outside, resulting in an increase in the internal pressure of the dust suction aperture 3. In turn, a suction force to be brought to the dust A sticking to the dust suction aperture 3 becomes low and under this state, the air is jetted toward the dust suction aperture 3 from a jet nozzle 17a. This jet stream hits the dust A sticking to the dust suction aperture 3 and the dust A is thrust forward.  Thus the dust A sticking to the dust suction aperture 3 is automatically removed from the aperture 3.

Title: Semiconductor memory
Inventor: TOYODA KAZUHIRO
IPC: G11C11/414
Filed: 1981-04-28
Abstract: PURPOSE:To avoid write error, by tentatively lowering a clamp level of non- selecting bit lines through a clamp circuit of a bipolar semiconductor memory at the switching of word lines. CONSTITUTION:Word driver transistors Q1, Q2...Qm are of multi-emitter construction, and one emitter is connected to each word line and other emitters are commonly connected to a wire l via a resistor R. Thus, the potential of the wire l is determined by logical sum of each word line potential as shown in dotted lines in Figure. Since the level of the wire l is a clamp level of non-selection bit lines through transistors Q13, Q14...Qn3 and Qn4, the level is tentatively lowered when the word lines are switched and returns to H level. Even when write is made through the changeover from non-selection to selection, since the rise in the collector potential of transistors at the ON side of semiselection cells is  slight and temporary, no mis-write is caused.

CONSTITUTION:When a key which is not shown is inserted into a lock body N and is turned by 180 deg. in its unlocking direction, an intermediate lever 37 is rotated counterclockwise by rotated cams 33, 34 through a mandrel 47 so that a pawl piece 35 is released from the ratchet teeth 18 of an internal gear ring 17, and therefore, a cap nut N becomes rotatable, thereby a wheel may be removed. When the key is turned by 180 deg. in its locking direction after the cap nut N is tightened, the small diameter section of the cam 33 faces the intermediate lever 37 so that a pressing spring 38 urges the pawl piece 35 to engage with the ratchet teeth 18, and therefore, the cap nut N is inhibited from rotating thereby the wheel is prevented from loosening. With this arrangement, the loosening of the wheel and the theft thereof may be surely prevented.
