Title: Overcurrent detecting circuit for switching regulator
Inventor: FUJIKAWA KATSUMI
IPC: H02M3/28
Filed: 1982-09-03
Abstract: PURPOSE:To stabilize a switching regulator by providing a timing pulse delay time generator and a time deciding circuit at the rear stage of an identifying circuit which identifies the variation in the collector current of the primary side main switching power transistor. CONSTITUTION:An overcurrent detecting circuit of a switching regulator identifies the variation in the collector current of the primary side main switching power transistor 6, thereby detecting the overcurrent. A time deciding circuit 48 is provided so as not to identify the overcurrent to a noise current which has a narrow width and a large amplitude, thereby extracting only the pulse current higher than the prescribed pulse width. Further, a timing pulse delay time generator 45 is provided to delay the collector current of the transistor 6 even if the duty cycle of the collector current of the transistor 6 is small to produce a pulse width near the pulse period of the transistor 6 by delaying the collector current, thereby effectively identifying the overcurrent.

Title: Image processor, imae processing method and storage medium
Inventor: YOSHITANI AKIHIRO
IPC: H04N1/46
Filed: 1997-06-11
Abstract: PROBLEM TO BE SOLVED: To embed additional information color image data in a way that the additional information is hardly identified by human eyes while suppressing deterioration in image quality of a received image in the case of forming a color through the use of pluralities of kinds of ink having different density by using a 2nd density recording agent so as to generate a pattern denoting prescribed additional information. SOLUTION: A scanner reads a color image generated by a printer 3 and extracts only a Y component of the color image. Furthermore, pixels formed by using dense ink and pixels formed by using light ink are classified based on the density of the image of the Y component to extract the image of the classified Y component. Thus, the additional information is added only to the Y image data and the additional information utilizes it that the Y image is hardly identified by human eyes. Moreover, a pattern denoting the additional information for the Y image data is forcibly formed by an image in light ink to form the image with high image quality more than the case with configuring the pattern by Y ink only.

Abstract: PURPOSE:To measure a local withstand voltage characteristic by executing a withstand voltage test to plural cylindrical slice pieces taken out of a cylindrical insulator. CONSTITUTION:By cutting an insulation reinforced body 1 into round slices, a cylindrical insulator piece 10 is obtained. Subsequently, by cutting successively the piece 10 from the outer peripheral side, thin cylindrical slice pieces 11 are obtained.

Next, by allowing flat disk electrodes 4, 4 to abut on one point in the thickness direction of this slide piece 12, dielectric strength is measured. Also, by moving the electrodes 4, 4 to other point, yield strength is measured. In such a manner, in accordance with a thickness stage in the diameter direction of a cylindrical insulator, a withstand voltage characteristic can be measured locally. Accordingly, the analysis of the insulation performance at the time when an insulator is used actually is facilitated, and also, which part in the insulator is weak against an electrical stress can be known exactly, therefore, in the case of forming the insulator by mold molding, etc., an optimum manufacturing condition can be easily found.
