Filed: 1998-05-26
Abstract: PROBLEM TO BE SOLVED: To shorten the information gain time for focusing by performing the ranging or the measurement of two-dimensional distribution of a defocus amount for a limited area and performing a follow up operation. SOLUTION: When a moving body photographing mode is set, and if present focus detective operation isn't the first, an area to be made as a detective object is set. For instance, in the whole focus detective area A of all 35 points constituted of vertically five divisions and, horizontally seven divisions, a main objective area B is decided by the last focus detective operation. Then, in the setting state of the present focus detective operation objective area, the area C in the vertical direction, the area D in the horizontal direction are set. As the number of the areas, it is narrowed to the number of 1/3 or below of the whole area. For instance, when the present main objective area becomes the area E, similarly, the next focus detective area operation area is set in the areas F, G.  The distance distribution of a field to be photographed is measured for the set focus detective area. In such a manner, the ranging or the measurement of two-dimensional distribution of the defocus amount is performed only for the prescribed area and the follow-up operation is performed based on obtained information.

Abstract: PURPOSE:To provide a feeder so designed that a shaft suspended, so as to be capable of vertical motion, above the delivery port at the lower part of a hopper is openably fitted with push-feeding pieces of hinge-type to feed in- hopper material to be fed toward said delivery port, thereby enabling said material to be smoothly delivered into a packing machine without incorporation thereof. CONSTITUTION:A material to be fed 2 consisting of an ingredient such as 'shao-mai' charged into hopper 1 is fed toward a delivery port 1a as follows: when a rod 7a in an air cylinder 7 is made to descend, both semilunar plates 3a, 3a of push-feeding pieces 3 closed at the lower end of a shaft 4 are allowed to descend while being opened to both sides with a pin as a support through the resistance of the in-hopper material 2, thereby feeding said material 2. Thence, when the rod 7a is raised, another batch of a material to be fed 2 is allowed to ascend smoothly to a specified position while closing the above semilunar plates 3a, 3a being in an opened state. Next, in this state, the shaft 4 is made to descend again, thus, automatically, continuously repeating operations similar to those mentioned above.

Title: Instruction control system
Inventor: UESUGI TAKAHIKO
IPC: G06F9/38
Filed: 1990-06-19
Abstract: PURPOSE:To make it possible to rapidly execute instructions even at the time of inputting a branching instruction by providing the instruction control system with a register for holding data determining information and a means for replacing the data determining information, and when branching is succeeded by the branching instruction, controlling a branched instruction so as to refer the data determining information obtained before outputting the branching instruction. CONSTITUTION:An instruction register 1 transmits an instruction and an operand supplied from an instruction supplying circuit to an instruction register 2. Respective registers 1, 2 are controlled by control signals outputted from an instruction stage control circuit 4 and a data determination control circuit 5. When branching is succeeded by a branching instruction, an instruction outputted after the branching instruction is delayed until the result preceding the branching instruction is determined by substituting the immediately preceding data determining information for the current data determining information, it is unnecessary to delay the instruction succeeding the branching instruction by the branching instruction until all the data of the instruction preceding the branching instruction are completed. Thereby, instructions can rapidly be executed even at the time of outputting the branching instruction.

Abstract: PURPOSE:To raise automatic correcting function of an electronic typewriter by using a system in which a printing section can be moved in the reverse order of the order of inputting even for back space over plural lines by storing character number for plural lines when the carriage is set back. CONSTITUTION:The address of the tip position of a compilation buffer 40 is stored, the address of the end position of the first line is stored in a pointer AP2, and the address of the end position of the second line is stored in a pointer AP3.

In correcting letters, when a back space key is operated, AP5=AP1 is compared and then it is judged whether AP5=AP3 and AP5=AP2 are satisfied. When one line is exceeded by operating the back space key, the carriage is moved to the end of the previous stage line, and consequently the carriage is orderly moved in the reverse direction of letter inputting.
