Abstract: PURPOSE:To secure the actuation of an IC chip even though a semiconductor memory element has several defective pits by using the semiconductor memory element that is not selected by address information and a comparator which decides the coincidence between the contents of plural registers and the address information. CONSTITUTION:An action test of a memory is carried out from the outside of the memory by a control IC for CPU, etc. Thus it is decided that the action of a memory element corresponding to a specific address of a main memory MAIN 7 is defective. Then the MODE is set at L and the operation is switched to a write mode on an ADR.REG 3 and the addresses corresponding to the defective pits are written on the REG 3. Meanwhile it is always checked by comparison at the inside of the memory whether or not the address information decoded by a decoder is coincident with the contents of the REG 3 stored as a defective address through a COMP 4. If the coincidence is obtained, coincidence signals CEphi-CEm are used as the selection signals for the specific memory element of a SUBMEMORY 5. Then a memory circuit is switched to the SUB 5 from the MAIN 7.

Filed: 1999-08-17
Abstract: PROBLEM TO BE SOLVED: To provide a digital watermark system by which information is surely and easily reproduced from an image, in which information is embedded, without using a standard image even when that image is changed. SOLUTION: An element information extracting part 13 extracts the element information of a character from the image data of a document acquired by a main information input part 11.

A main information reconstituting part 18 changes image data on the basis of the changed element information and a main information output part 19 prints the document expressed by the changed image data.  When the element information extracting part 13 extracts the element information from the document in which the copyright code is embedded, a sub-information reading part 20 extracts the sub-information from the extracted element information and the prescribed part of that sub-information is displayed by a sub-information output part 21 as a copyright code.

Abstract: PURPOSE:To improve engine stall resistance by using a power steering mode when power steering is detected to be actuated before hanging to idle drive and an economy mode when the power steering is not actuated, during idling. CONSTITUTION:A control unit 40, which inputs signals output from an idle switch 9, a crank angle sensor 22, a shift range sensor 26, a water temperature sensor 31 and a wheel speed sensor 33, judges wether a vehicle runs over a preset speed (about 30km/h) or not before changing to idle drive under a warm-up condition. When judging YES, it judges a power steering switch 32 is OFF or not before changing to idle drive after exceeding a preset speed, and when it is OFF, if now under an idling condition, an economy mode is set. On the other hand, the vehicle does not run over the preset speed under a cool-off condition and the power steering switch 32 is ON, if now under idling condition, a power steering mode is set.
