IPC: F02D41/20
Filed: 1981-08-14
Abstract: PURPOSE:To obviate operation errors in a starting control, by storing the step value of a step motor driving a throttle valve, while transferring this value to another memory at the time of power failure in an electron device. CONSTITUTION:Signals from each sensor are inputted into a CPU46 for electronic circuits for engine control use via an A/D converter 47, an input/output interface RAM48 and an ROM input/output interface 49. In time of idling, it controls the pulse motor step value of a solenoid control valve 26 which drives a throttle bypass valve and regulates the number of idling revolution. The step value is stored in a second RAM50 powered by a sub-power source 54 connected to a battery 40 at all times, in a separate system other than an electric control circuit power source 54 connected to the battery 40 via an ignition switch 38 and then this stored value is transferred to a first RAM48 when the main power source is out of order.

Title: Path searching device
Inventor: YAMAMOTO JUNICHI
IPC: G08G1/0969
Filed: 1995-05-25
Abstract: PURPOSE: To search a path not making a U-turn around a relay point. CONSTITUTION: On the basis of a start point, a relay point and an objective point inputted from an input means 3, a path searching means 4 searches a path following these points in regular succession. The attribute of the relay point can be set to either one of a stopover point and a passing point. When the relay point is set to the stopover point, the path searching means 4 computes an angle formed by a road part connected to the relay point of a second path reaching the objective point from the searched relay point and a road part connected to the relay point of a first path reaching the relay point from the start point. Large weight is added to road part having a small angle and turning back after a U-turn around the relay point. The road part with small weight out of a plurarity of searched road parts is determined as a road part forming the recommended path of the second path.  According to the determined recommended path of the second path, a path guide means 9 displays the recommended path and the position of an own vehicle on the display image plane of an output means to perform path guidance.

Filed: 1987-05-26
Abstract: PURPOSE:To facilitate judgment the front focus, the rear focus, or the in-focus state to move a photographing optical system, display the degree of focusing, etc., by detecting the degree of focusing in accordance with the interval between two images on an optical sensor array of respective luminous fluxes passing different parts of the photographing optical system. CONSTITUTION:When the photographing system is in the in focus state, the interval between a pair of images A and B is equal to intervals D between lens systems 9 and 10 and lens systems 9' and 10' if the luminous flux emitted from a variable power lens group 2 is parallel rays. When the photographing system is in the front focus state, a pair of images A nd B are shifted inward from those for the in-focus state and blur because the luminous flux emitter from the variable power lens group 2 is a converging luminous flux. When the photographing system is in the rear focus, a pair of images A and B are shifted outward from those for the in-focus state and blur because the luminous flux emitted from the variable power lens group 2 is a diverging luminous flux. Photoelectrically converted outputs of a pair of images A and B are operated to obtain a deviation (x) from positions of images for the in-focus state, thereby judging the front focus, the rear focus, and the in-focus state.

Abstract: PURPOSE:To prevent the access of a third person to data information by providing the 1st and 2nd recording media which respectively record address information and data information so as to separate the two kinds of information from each other. CONSTITUTION:Upon inputting an instruction outputted from a CPU 2, a control section first reads out address information from the 1st recording medium 4 and tentatively stores the information in a storing section 7 in the case of reading out data information. Then the section 6 reads out the data information from the 2nd recording medium 5 in accordance with the address information stored in the storing section 7 and sends the read-out data information to the CPU 2 through an input-output interface section 3. At the time of recording data information, on the other hand, the section 6 first stores received address information and the data information in the storing section 7. Then the section 6 reads out the address information stored in the section 7 and registers the address information in the medium 4. Thereafter, the section 6 reads out the data information stored in the section 7 and writes the data information in the medium 5 in accordance with the simultaneously read-out address information. Thus the access of a third person to the data information can be prevented.
