Title: Image processor
Inventor: NAKAYAMA TADAYOSHI
IPC: H04N5/278
Filed: 1989-02-16
Abstract: PURPOSE:To execute diverse image processing with a simple constitution by composing the processor of an image memory, a line delaying means, an image data enlarging means, a binarizing means, the outline detecting means of a binarized image, and an image data replacing means. CONSTITUTION:One picture is fetched into an image memory 302. Next, the reading speed of the memory 302 is made half, and the image data are transferred to a line delaying circuit 304. Next, the image data of the circuit 304 are rotated once. Thus, the data in the first line of still image data are enlarged two-fold in an X direction. Next, by the above-mentioned circuit, the still image data are made two-fold also in a Y direction. A binarizing circuit 307 binarizes the enlarge-processed image data and supplies them to a line delaying circuit 308, an outline detecting circuit 309 and an AND gate 316. A data selector 312 replaces the image data in the part, in which the binarized image data are logic 1, with superimpose level data. The data selector 313 replaces the above-mentioned image data with outline level data. Thus, the outline part is made into the image to be contrasted.

IPC: G01B7/00
Filed: 1986-02-20
Abstract: PURPOSE:To improve the measurement accuracy of an encoder by arranging respective magneto-resistance effect (MR) elements in a block at specific intervals when intervals of N and S poles magnetized on a scale are denoted as lambda. CONSTITUTION:When the intervals of the N and S poles magnetized on the scale are denoted as lambda, 2n (n: positive integer) MR elements in the block are arranged at the specific intervals d0=(2u-1)lambda.

Then, a conductive material is vapor-deposited over the entire surface of a nonmagnetic substrate to about 0.2-5mum and then patterned in a specific pattern to form a wiring pattern for a bridge. Then, an MR element material is vapor- deposited entirely thereupon to about 0.01-1mum thickness and patterned to form eight MR elements M1-M8, and an amplifying circuit and a rectangular wave converting circuit are fitted to a terminal where an original signal is obtained, thus completing a magnetic head.

IPC: F23N5/24
Filed: 1998-02-18
Abstract: PROBLEM TO BE SOLVED: To prevent unwatered heating of a gas water heater, by monitoring the consumption states of gas and water. SOLUTION: A gas hot water heater is assumed to be in use by means of a tool-in-use assuming portion 23 on the basis of gas flow rate signals detected by a gas flow rate detecting means 22. When a hot water heater-in-use signal is outputted, communication is made between an external communication means 21 for a gas cutoff device and an external communication means 12 for a water meter. In the case where a water supply is undetected by a water supply detecting means 11, a shut-off valve drive portion 24 outputs a cutoff signal for preventing unwatered heating of the gas hot water heater according to the hot water heater-in-use signal and the communication resulted in non-use of the water supply, thereby cutting off a gas supply path with a gas shut-off valve 25 being driven.
