摘要:
Address information generated and output by an address converter for each pixel of input image data in accordance with the phase based on the position of the pixel to be coded is stored in an address storage divided into address groups which are periodically referred to. Information indicative of the occurrence probability of the pixel to be coded and phase information of the pixel are selectively output from the address storage, and an arithmetic coding is performed for the output. During the processing, update data is written in to one group while a read-out is being performed for the other group. A template is constituted by excluding a pixel which predeses one pixel, and a prediction state in each phase is divided into two parts. The template output is applied to both of the divided storage devices, and read actions are independently performed.

In a crankshaft 200, one hole 213L formed in a crankpin 213 has a bottom surface having a larger area and a depth from a surface of the crankpin less than those of another hole 213M. In forming the hole 213L and the hole 213M, a preformed product 200 of the crankshaft having a shape smaller than that of a cavity is disposed in a die set and punches are simultaneously inserted into the crankpin 213. By this operation, the hole 213L and the hole 213M are simultaneously formed in each crankpin 213 of the preformed product 200.

摘要:
A charge control circuit which prevents charging of a battery when a charger is connected to the battery when the voltage of the battery is not above a threshold voltage of a MOS inverter circuit. Under such a condition, a charge control switch is turned off and charging current is cut off so that charging of the abnormal battery is inhibited and destruction or explosion of the battery is prevented. First and second circuits monitor the battery voltage, the second circuit having for comparing the battery voltage to a threshold voltage of a MOS transistor, and a logic circuit performs a logic operation on the outputs of the two circuits so that charging of the battery is prevented when the battery voltage is not higher than the threshold voltage of the MOS transistor.
摘要:
An image coding device for coding image data by means of an arithmetic code detects bit positions of value "1" in a register which stores a plurality of bits of interval data representing a current coding interval used for coding image data. Subsequently, the image coding device shifts the interval data in the register according to the bit position.

A layered body (1) is provided in which a first layer (3) is deposited at one side on at least one surface of a resin substrate (2), a second layer (4) is deposited on the other side of the first layer (3) opposite to the one side thereof at which the first layer (3) is deposited on the resin substrate (2), the first layer (3) is a first organic-inorganic hybrid layer containing a (meth)acrylic resin and a silane compound, and the second layer (4) is a second organic-inorganic hybrid layer obtained by curing a composition made of a solution obtained by hydrolysis and condensation using a composition which contains a silane compound (A) containing at least one epoxy group and represented by the following Formula (1), an aluminum alkoxide (B) represented by the following Formula (2) and a tetrafunctional silane compound (C) represented by the following Formula (3): Si(R1)p(OR2)4-p Formula (1); Al(OR3)3 Formula (2); and Si(OR4)4 Formula (3).
摘要:
A data management method which causes equipment such as a camera integral-type recording and reproducing apparatus to manage an external reference type container file and an audiovisual stream file by setting an attribution of all the external reference type container files recorded in a disk to an invisible state. Therefore, reproduction of the container file can be performed in the main body of the equipment, and only the audiovisual stream file can be reproduced when the disk is reproduced in, e.g. a personal computer.

There is provided a method by which a member having an undercut in the inner peripheral portion thereof can be formed readily. To form a material (1) formed with a recess (2) and the undercut (3) by using a swaging device, while the material (1) is first gripped by a damper (11), and a mandrel (12) is inserted into the recess (2) of the material (1). The mandrel (12) used has an outside diameter equal to the inside diameter of a blind hole of an aimed product (fuel injection nozzle). Then, the material (1) is pushed in by the mandrel (12) to a position at which the material (1) abuts on a stopper (13), and the outside surface of the material (1) is struck by swaging dies (8) to perform a swaging operation. This swaging operation reduces the inside diameter of the recess (2) to the outside diameter of the mandrel (12), with the undercut (3) left.
