Title: Direct current constant voltage source circuit
Inventor: OOKI TOSHIMI
IPC: G05F1/56
Filed: 1978-09-26
Abstract: PURPOSE: To always obtain a constant output regardless of the fluctuation of the load or the power voltage by providing the emitter follower circuit, the constant current circuit and the negative feedback circuit between the diode and the output terminal.  
     CONSTITUTION: When the voltage of output terminal 6 increases by some reason, the overlap voltage of resistance 7 increases and is then inverted by the inverter consisting of transistor Tr9 and resistance 10 to be turned to the gate input voltage of Tr11. Thus the channel resistance of Tr11 increases, and the current flowing through resistance 12 and Tr11 decreases. As a result, both the voltage across resistance 12 and the voltage applied between the gate and the source of Tr13 decrease. Accordingly, the current flowing into diode 2 from Tr13 decreases and its forward voltage also decreases. This decreases the emitter current of Tr4 and then reduces the voltage increment of terminal 6. The lowering of the output voltage, if occurs, can be prevented by giving the opposite action to that mentioned above.

Abstract: PURPOSE:To improve an encoding efficiency by reducing a visual redundancy. CONSTITUTION:An orthogonal converter 11 divides picture data into plural blocks constituted N pieces of picture elements in both horizontal and vertical directions at every frame, and discrete cosine-converts the picture data at every block. As for a conversion factor transmitted from the converter 11, the conversion factor corresponding to a low spatial frequency is multiplied by a large numeric value, and the conversion factor corresponding to a high spatial frequency is multiplied by a small numeric value by a weighting equipment 12. The absolute value of each conversion factor weighted like this is squared by an absolute value squaring equipment 13, and they are added to each other by an adder 14 in order to calculate the total sum (sum of squares of absolute value) of each block. The sum of squares of absolute value are stored in a memory 15 at every frame. The large number of bits are assigned to the block whose sum of squares are large, and the small number of bits are assigned to the block whose sum of squares are small by a bit distributor 16, based on the value of the sum of squares of absolute value stored in the memory 15.

IPC: B62M25/06
Filed: 1996-05-14
Abstract: PROBLEM TO BE SOLVED: To continuously change the traveling speed with a simple structure by providing such a constitution as to extend and contract the driving radius (rotating radius) of a chain 12 in the axial part of a pedal crank every time when the pedal crank is reversely rotated when a bicycle is traveled by the normal rotation of the pedal crank.
