摘要： PROBLEM TO BE SOLVED: To obtain a detecting apparatus, for the position of a moving body, in which the number of required accelerometers can be reduced and which can detect the position by a simple structure. SOLUTION: A first accelerometer 1, a second accelerometer 2 and a third accelerometer 3 are arranged in such a way that their detecting axes are mutually parallel. The first and second accelerometers 1, 2 are arranged in the up and down direction so as to be separated by r1, and the first and third accelerometers 1, 3 are arranged so as to be separated by r2 in the horizontal direction. Then, the direction of the detecting axes is set as the y-axis, the horizontal direction perpendicular to the y-axis is set as the x-axis, and a direction which is perpendicular to the y-axis and the x-axis is set as the z-axis. Then, an acceleration 1 around the x-axis is found on the basis of the difference between the first and second accelerometers 1, 2, and the angle of inclination θ1 of an automobile is found on the basis of the acceleration ω1. Then, when the detected acceleration of the first accelerometer 1 is designated as a1, an acceleration in the y-direction is found on the basis of a1-g.sinθ1. When an acceleration (a1-g.sinθ1) cosθ1 in the horizontal direction is integrated, the position of the automobile is found.

摘要： PURPOSE:To prevent the penetration of a resin solution into a recessed part at the time of dipping and obviate secondary processing such that a small diameter part is cut off after molding to form an opening by forming the recessed part depressed along the axial direction of a mold to the leading end surface dipped in the resin solution of the mold. CONSTITUTION:A mold 1A is formed into a two-stage columnar shape having a large diameter part 1b and a small diameter part 1a and the whole outer shape thereof corresponds to the inner shape of a molded product 7A having a through-hole 6, a large diameter part 7b and a small diameter part 7a. In this case, the recessed part 2 depressed along the axial direction of the mold 1a is formed on the leading end surface 1c of the small diameter part 1a of the mold 1A. At the time of molding, the mold 1A is heated and supported so that the leading end surface 1c of the small diameter part 1a is turned downwardly to be dipped in the PVC solution 5 stored in a tank 4. Hence, air before dipping is taken in the recessed part 2 to form an air layer and, therefore, no solution 5 penetrates into the recessed part 2. As a result, a molded product 7 has an opening 6c formed to the recessed part 2 to which no resin is bonded.

CONSTITUTION:Leaflike pressing parts 4a and 5a are provided by forming notches in a plate material 1a. The pressing parts 4a and 5a are conformed with their tip parts made protruded and recessed shapes in a plane view respectively. The pressing parts 4a and 5a are mutually overlapped at their tip parts by making the tip part of the pressing part 5a bend in its width direction to be formed, and protruding the precessing parts 4a and 5a in a main body 3a. The pressing parts 4a and 5a are provided by forming notches in the plate material 1a, resulting in the small area of the plate material 1a and the low material cost. A plug is elastically pressed toward an inner surface of the main body 3a with the pressing parts 4a and 5a in a condition where their tip parts are overlapped, with an excellent electrical characteristic and durability as electrical connection pieces.

摘要： PURPOSE:To transmit normal data even when a transmission path is disconnected by connecting a multi-drop bus in ring shape, and deciding the length of the multi-drop bus so as to transmit data being transmitted in right turn and the data being transmitted in left turn within a specified period. CONSTITUTION:The transmission path 7 in a data transmission network connected between electrical equipment to be loaded on a vehicle is comprised by connecting the multi-drop bus in the ring shape. The length of the multi-drop bus is decided so that data on the other side can arrive at a node being set a reception state within the period until a bit is sampled first from the beginning at the time of reading the data bit by bit in the node where each bit of the data is set at the reception state arriving at the node set at the reception state first out of the data being transmitted in the right turn and the data being transmitted in the left turn from the nodes A-H set at transmission states to the nodes A-H set at the reception states. In such a way, it is possible to perform the transmission of the normal data even when the disconnection is generated at a point K on the transmission path.

摘要： PURPOSE:To aim at the promotion of inexpensiveness in constitution and of a small diameter in wire harness, by installing each multiconvertion circuit in the vicinity of a switching element, driving load to come on or off, and a trouble displaying element, and displaying each state of load driving parts via each of these circuits aforesaid. CONSTITUTION:A multiconvertion circuit 25 is housed in the relay box 7 installed in the vicinity of loads 5-1-5-N, and each time the specified time elapses, each output of respective trouble detecting circuits 19-1-19-N is read in at the said circuit 25, putting a master mark or an end mark or the like on converted serial data, and they are outputted to a signal line 26. On the other hand, each of lamp driving circuits 28-1-28-N and a multiconvertion circuit 29 are installed in the vicinity of trouble displaying lamps 14-1-14-N at a driver's seat. And, the said serial data are converted into parallel data by the multiconvertion circuit 29, and these data are outputted to these lamp driving circuits 28-1-28-N. According to this method, it will do that an electric cable 12 alone uses a thick one, and there is unnecessary to be formed into fail-safe constitution.

摘要： PURPOSE:To reduce the effect of noises on other electrical parts by connecting a switching element between power applying terminals for a motor, bringing the switching element to an ON state and applying braking to the motor. CONSTITUTION:When a switch 3 is closed, a motor M is supplied with the DC voltage of a battery 2 through a diode 7, and the motor M is turned. When the switch 3 is turned OFF, a transistor 8 is brought to an ON state by back electromotive force generated in the motor M. Accordingly, both terminals T1, T2 for the motor M are short-circuited, thus applying braking to the motor M.
