Title: Support mechanism of thermal printing head
Inventor: MAEKAWA NOBUKI
IPC: B41J25/312
Filed: 1988-03-08
Abstract: PURPOSE:To facilitate the mounting and detachment of a thermal printing head with respect to a main body and to rapidly perform cleaning or replacement, by providing a protruding part to a printing head holding plate, which fixes a thermal printing head to integrally hold the same, to set the same to the center of revolution of said holding plate. CONSTITUTION:The power point 8b of a head pressing spring 8 is raised by a fingertip and the protruding part 2a of a holding plate 2 is moved in a C- direction while the engagement of the holding plate 2 with the power point 8b is released to be separated from the groove part 5a of a main body 5 and the holding plate 2 is taken out of the main body 5 to make it possible to easily clean or replace a thermal printing head 1. The replacement of the thermal printing head 1 can be simply performed by loosening a screw 3 to detach the thermal printing head 1 from the holding plate 2 to mount a new thermal printing head to said holding plate 2. Next, when the thermal printing head is mounted to a printer after predetermined inspection or replacement work is finished, the procedure entirely reverse to the detachment procedure is repeated. At this time, by rotating a platen 7 in an A-direction, the thermal printing head 1 becomes the original position.

IPC: H01L21/027
Filed: 1998-03-06
Abstract: PROBLEM TO BE SOLVED: To expect mutually conflicting advantages of high throughput and an accurate alignment by correcting the error in the degree of orthogonal crossing of an array based on three positions that are not on a straight line of a first original picture pattern and exposing a second original picture pattern so that it overlaps with the first original picture pattern. SOLUTION: For example, when a chip is in an array of five rows and five columns and is extended in X direction, five chips where a center chip is placed and each one chip is arranged in the directions of X and Y axes from the center chip are used as chips for detection. Assuming that the coordinates of the center chip are detected as (x0 , y0 ), the coordinates of two chips in X-axis direction are detected as (xa, ya) and (xb, yb), and the coordinates of two chips in Y direction are detected as (xc, yc) and (xd, yd), (x1 , y1 ) and (x2 , y2 ) are obtained from the three detected coordinates by the least square method to determine the array of a chip with five rows and five columns. Even if the transferred original picture pattern contains a distortion, an overlapped transfer can be made accurately.

Title: Driving device for cloth holding body for sewing machine
Inventor: TAJIMA IKUO
IPC: D05B29/00
Filed: 1991-02-26
Abstract: PURPOSE:To adjust the stroke itself of a vertical operation of a cloth holding body by a simple operation by setting a coupling point for transmitting turning force to a second driving lever for operating vertically the cloth holding body to an arbitrary distance against a turning fulcrum of the second driving lever. CONSTITUTION:At the time of reducing a stroke S from a state set to the maximum of a nipple (cloth holding body) stroke S, an adjusting lever 96 is turned by rotating clockwise a nipple raising shaft 22. In connection therewith, a pin 89 moves along a circular arc 92 of a second driving lever 90 through a second joint lever 97, a point of application (pin 89) of turning force to a second driving lever 90 is separated from an axis center point of the nipple raising shaft 22 being a turning fulcrum of a second driving lever 90. As a result, the turning amount of a second driving lever 90 becomes small without exerting any influence on a full line position (a bottom dead center position of the nipple) of a second driving lever 90. Accordingly, the bottom dead center position of the nipple is as it is and the nipple stroke S becomes small.
