摘要： PURPOSE:To enlarge the turning torque of a movable magnet by applying an inverting output of a sine wave (cosine wave) voltage applied to one terminal of a cross coil to the other terminal and making the potential difference between both terminals of the coil large. CONSTITUTION:Using a sine wave and a cosine wave as a signal source in this gauge, the outputs of amplifiers 7, 8 are applied to one terminals 2b, 3b of two cross coils 2, 3 when A times amplifiers 7, 8 are used. Each signal source is inverted around a predetermined voltage, and applied to the other terminals 2a, 2a of the coils 2, 3 by inverting -A times amplifiers 5, 6. Therefore, the potential difference between two terminals of the coil becomes large, so that the turning torque of the movable magnet can be enlarged.

摘要： PROBLEM TO BE SOLVED: To provide a pressure detector for ensuring linearity in temperature characteristic of the detector without obstructing displacement of a diaphragm even in the case of low temperature of the ambient temperature of a service environment. SOLUTION: A pressure sensor chip 5 detects pressure of fluid such as gas, liquid or the like. The chip 5 is arranged on a metal base plate 13. A case (containing case) 12 has first and second openings 12a, 12b, which have an extended part 12c protruding in an inside direction and formed between the openings 12a and 12b. And, the plate 13 is fixed to the opening 12a side of the part 12c to form a bottom, and constituted by a containing part for containing the chip 5. A metal diaphragm 9 is arranged in the opening 12b of the case 12. Silicone oil 11 is poured in the containing part of the case 12. A space 15 is formed so that the diaphragm 3 is displaceable in a downward direction between the diaphragm 9 and the part 12c.

摘要： PURPOSE:To eliminate delay in the informing timing, and inform the fact in the proper timing by judging an acceleration condition where travel speed reaches informing speed and approach to the informing speed, and outputting an informing signal almost simultaneously when the travel speed reaches the informing speed. CONSTITUTION:Automobile travel speed detected by a vehicle speed sensor 1 is outputted as pulse signals having a frequency in proportion to these, and is inputted to an operation part 2 after waveform shaping. The operation part 2 counts the inputted pulse signals in a prescribed gate period, or measures an inputted pulse signal period by a reference clock signal, and calculates travel speed periodically, and outputs acceleration to a control part 3 by carrying out operation. The control part 3 finds out how many seconds later preset information speed is attained if an increase in present acceleration is continued at present speed according to travel speed data and acceleration data from the operation part 2, and judges to inform the fact when this is the preset time, and outputs an informing signal to a voice synthesizing part 5.

摘要： PURPOSE:To reduce amount of transmission data as well as to prevent the delay of transmission rate and data transmitting time and an increase of mistransmitting probability from occurring by installing a nonvolatile memory, renewing an integrating travel distance according to distance information at each fixed travel distance from a transmission unit, in a receiving unit. CONSTITUTION:A receiving unit 3 consists of a second communication part 31 receiving a multiple signal out of a transmission unit 1 and getting distant information, a processing part 33 changing an integrating travel distance in the storage contents of a nonvolatile memory 32, to the latest value by the distance information, while delivering a display signal at each unit travel distance running, and a display 34. In succession, the processing part 33 renews the integrating travel distance of the memory 32 by the distance information being delivered via a transmission passage 2 from the unit 1 each time a car travels the unit travel distance, thus display contents are renewed to the latest value at the specified time. With this constitution, the integrating travel distance itself becomes unnecessary to be transmitted from the unit 1, an amount of transmission data is sharply reduced in this way.
