Title: Method for forming both sides of forming material
Inventor: KAWADE YASUO
IPC: B29K105/04
Filed: 1987-08-20
Abstract: PURPOSE:To form uneven patterns on both sides of a foaming material only with a single mold and consequently shorten the processing time by a method wherein the foaming material, one side of which abuts against the mold and the other side of which abuts against a hot plate, is hot-pressed under the state that the heating temperature on the mold side is set lower than that on the side opposite to the mold side and the hot-pressed foaming material is released before the completion of forming. CONSTITUTION:An aperture plate (mold) 7 is mounted onto a lower side hot plate 6 and a foaming material 4 is placed on the aperture plate 7 so as to hot-press the material with hot plates 5 and 6. As the temperature conditions in this case, the temperature of the hot plate 5 is set to be higher than that of the hot plate 6. The foaming material 4 is released before the forming completes. The material in the neighborhood of the squeezed part 3 tends to yield to the back side of the projected part 1, in which internal activity is left, resulting in generating the swollen part 2 with the shape corresponding to that of the projected part 1 on the rear side of the projected part 1.

Title: Thermal writing device
Inventor: KAKINUMA TAKEO
IPC: B43K8/00
Filed: 1996-08-06
Abstract: PROBLEM TO BE SOLVED: To carry out writing capable of being distinctly discriminated from a printer printed part. SOLUTION: When writing is carried out on a thermal recording medium 32 by using a hot pen 10, a heating part 16 of the hot pen 10 is heated according to a temperature changing pattern turning on and off in a timewise specific pattern, for example, at 5msec intervals. Therefore, a dotlike line obtained as a result of regularly heating is written in a written part (a writing part 36) on the thermal recording medium 32. Besides, in the case of printer printing, in order to print on the thermal recording medium by continuing a heated state with a heating part for printer printing, a continuous line of a specific line width is written on a part printer-printed on the thermal recording medium (a printer printing part 34).  Therefore, though the printer printing part 34 and the write part 36 exist on the same thermal recording medium, both can be definitely discriminated based on a kind of the line.

Title: Offset correction method of arm position in x-y type circuit board inspection equipment
Inventor: ISHIKAWA HIROTAKA
IPC: G01R31/28
Filed: 1993-07-29
Abstract: PURPOSE:To minimize fluctuation in the positioning of arm regardless of the distance from the original point by determining the central value of maximum shifts and correcting the coordinate data of one arm such that the target point, viewed from that arm, comes in the center. CONSTITUTION:After each arm L, M, R is positioned with respect to an original point by means of a digitizer D, each arm L, M, R is provided with same probing data so that the arm circulates the working area starting from the original point. A CPU obtains the coordinates at the probing point of one arm as a target point data and that of the other arm as a comparing point data from the digitizer D. Subsequently, the CPU detects maximum shifts in + and -directions, for both X and Y axes, among the shifts of the comparing point data from the target point data. The central values of maximum shifts in the direction of X and Y directions are then employed as correction values for each coordinate data.

Abstract: PURPOSE:To reduce variation in display value without imparing the contents of a data having a pulse train by setting a threshold for shift from a pointer to a pointer higher or lower by one than in and a threshold from a pointer higher (or lower) by one than the pointer involved so as to be positioned in zones adjacent to each other. CONSTITUTION:When the contents SIGMANi of a total counter 42 are updated to be SIGMA2<21>Ni, the SIGMA2<21>Ni is compared with the preceding total counts SIGMA1<20>Ni memorized in a buffer memory 45 by a comparator 46 to discriminate difference in the magnitude between SIGMA2<21>Ni and SIGMA1<20>Ni. Thereafter, the memory contents of the buffer memory 45 are updated to SIGMA2<21>Ni. Then, according to SIGMA2<21>Ni>=SIGMA1<20>Ni or SIGMA2<21>Ni<SIGMA1<20>Ni, a comparator 47 compares SIGMA2<21>Ni with the upper threshold or lower threshold of a pointer currently outputted from a D/A converter 5 via a table 44. When the SIGMA2<21>Ni is above the upper threshold, a pointer shifted by -1, that shifted by +1 when it is therebelow or that the same as before when it is between the upper and lower thresholds is outputted to the D/A converter 5.
