Title: Method of image contraction
Inventor: ICHIKAWA TADATSUGU
IPC: G06T3/40
Filed: 1989-01-30
Abstract: PURPOSE:To attain the rapid processing of contraction by using a process for obtaining an added value of reference picture element values determined in accordance with contraction ratios and a process for converting a picture element having digits smaller than the number M of digits required when the added value of the reference picture elements is expressed by a decimal number into the data of N planes expressed by a bit for the contraction. CONSTITUTION:Added values, e.g. a11 to a28, to be inputted to a reference picture element added value memory 4 for calculating the added value of reference picture elements and the data in the 1st line and the 1st byte are inputted to a reference picture element adding means 1. Since the initial reference picture element interval data is '0', the value is shifted to the right by one bit by a shift register 1A, a picture element P112 is moved to the 1st bit position, the P112 is similarly extracted by a mask circuit 1B and added to Q11 by an adder 1C. Similarly, a P113 is extracted and added to a Q11 to end the processing of three reference picture elements. Thus, each three picture elements are processed, the maximum value of the added value is set up to '9' and the necessary number of digits is set up to a value less than M4 only by one.

Abstract: PURPOSE:To perform skip stitching by a method wherein a sliding part is provided with a fixed side holder and a driving side holder to hold a spindle of a needle bar connecting bracket, the driving side holder is rotated by projecting an action pin of a solenoid so that the spindle of the needle bar connecting bracket comes off. CONSTITUTION:When jump stitching is performed, a solenoid 50 is put in action to project an action pin 50a so that a tip 35e of a swing arm 35d of a needle bar connecting bracket lever is connected to the action pin 50a. The tip 35e of the swing arm 35d descends, and a holder on the lower face of a protrusion 35b of the needle bar connecting bracket lever rotates counterclockwise and diagonally moves upward from a spindle 45a of a needle bar connecting bracket so that the connection between a sliding part and a needle bar is released. The action pin 50a of the solenoid 50 is connected to the swing arm 35d of the needle bar connecting bracket lever every time the swing arm 35d of the needle bar connecting bracket lever approaches near the upper dead point while the action pin 50a of the solenoid 50 is projected. Therefore, the spindle 45a of the needle bar connecting bracket is disconnected from the other holder and the needle bar is kept stopped at the upper dead point, so that skip stitching is carried out as stitching action does not takes place.

IPC: H03F3/343
Filed: 1978-02-20
Abstract: PURPOSE:To perform level shift well by giving not only a level shift operation but also a prescribed gain or attenuation quantity as required in a simple constitution. CONSTITUTION:In this circuit, the DC level of the emitter of outputting emitter follower transistor Q4 is 0, and the AC level is (R1+R2)ei/R1 when input signal components are ei. Consequently, the DC and AC level of the potential at output end OUT is -R3VEE/(R3+R3);(R1+R2)/R1xR3ei/(R3+R4); and when R2/ R1=R4/R3 is set, the AC level of the output potential is equal to ei, and a simple DC level shift is performed. When R2/R1not equal to R4/R3 is set, a level shift operation having a prescribed gain or attenuation degree can be performed by making the output AC level larger or smaller than ei.
