Abstract: A touch sensor device comprises: a touch sensor 1 for sending out an output voltage signal S1 representing the presence or absence of an operation; an operation presence/absence determination unit 2 which, when the output voltage signal S1 has a value equal to or more than a predetermined threshold value, determines that the operation has occurred; a stability determination unit 5 for detecting whether a differential signal S3 representing a differential value obtained by differentiating the output voltage signal S1 is limited within a predetermined range or not; and a count-up timer 4 which, when a period during which the differential signal S3 is limited within the predetermined range becomes a predetermined time period or longer on the premise that the output voltage signal S1 has the value equal to or more than the predetermined threshold value, sends out an ON determination signal S5 and allows an external device 7 to operate.

Abstract: A detection circuit 1 includes: an input unit 2; two contact electrodes A and B which are connected to the input unit; phase invention means 3 connected to the contact electrode A; one amplification means 41 arranged in each contact means; and detection means 5A and 5B which detect as an electric change amount, an amplitude change of an input signal caused by a capacitance change in each of the contact electrodes A and B. The detection circuit 1 causes the two electrodes to input signals having phases shifted by a half period from each other by using the phase invention means 3. In the presence of contact, the amplitude of the input pulses is amplified by the one amplification means 41. The respective detection means 5A and 5B detect signals of respective electrodes from the one amplified signal and output them to output units 6A and 6B, respectively.

Abstract: A touch switch structure is provided that can be preferably used for an automotive instrument panel and can securely prevent misjudgments and incorrect detections with respect to operations on the switch. For that purpose, the touch switch structure comprises a base material 2 made of a nonconductive material; a shield electrode layer 4 made of a conductive material and formed on one surface of the base material 2; a touch detection electrode 3 formed on one surface of the base material 2 at the portion where the shield electrode layer 4 is not formed; and an insulation layer 5 made of a nonconductive material and formed at least between the shield electrode layer 4 and a connection pattern 6 of the touch detection electrode 3.

Abstract: An EL emitting touch switch includes first electrodes, a single second electrode facing the first electrodes, and EL layers each sandwiched between a corresponding one of the first electrodes and the second electrode. A light emission driver applies a driving voltage between the first and second electrodes to cause the EL layers to emit light. A timing signal generator generates a timing signal to control the light emission driver such that the application of the driving voltage is stopped at predetermined intervals. Touch decision units are provided for each first electrode. Each touch decision unit includes a feedback circuit for supplying current to the corresponding first electrode such that the potentials of the first and second electrodes become equal to each other, and detects contact of a human body with the corresponding first electrode based on operation of the feedback circuit while the application of the driving voltage is stopped.

Abstract: The present invention relates to a structured touch switch, which is of an electrostatic capacity type. The structured touch switch comprises a substrate made of a material having a non-conductive characteristic, a conductive member made of a material having a conductive characteristic and formed integrally with the substrate so that a portion of the conductive characteristic member appears at a surface of the substrate and a detection electrode positioned at a backside of the substrate and in opposed relation to the conductive member in a state where a space is defined with respect to the conductive member.

Abstract: A touch switch is composed of an EL light emitting layer configured by stacking a fluorescent layer and an insulation layer between first electrodes and a second electrode, a judgment means for making a judgment on touch manipulation with the first electrode by an operator and an EL driving unit for driving the EL light emitting layer for light emitting, with each of a plurality of first electrodes, each of plurality of fluorescent layers and each of plurality of insulation layers being provided as a set and the second electrode being provided as a single electrode with respect to the plurality of first electrodes, wherein the judgment means makes a judgment on which of the plurality of first electrodes has been touched by an operator on the basis of a high-frequency component inputted from the second electrode through the first electrode each time the touch switch is touched by an operator.

Abstract: An acceleration sensor, which can always maintain a supporting body at a predetermined angle even when an inclining member is inclined and in which, moreover, a tilt lock angle is small. A substantially U-shaped limiting protrusion 136 is provided standing at a face wheel 130, and predetermined clearances are formed between the limiting protrusion 136 and a limiting shaft 138 of a bracket 40. When a seatback is inclined, the face wheel 130 rotates around an axis line J at the same angle as an angle of inclination of the seatback, and the bracket 40 is rotated with respect to the seatback by the load of a weight 118. Thus, a center line C of the bracket 40 is kept in a vertical direction. Even if a difference occurs between the angle of inclination of the seatback and the angle of rotation of the face wheel 130, the center line C of the bracket 40 is always in the vertical direction, within the clearances, due to the weight 118's own weight.

Abstract: An object of the present invention is to obtain an acceleration sensor that can reliably detect acceleration when inclination of an inclining member is within a fixed range, and that can reduce unnecessary movement of relevant members when inclination of the inclining member is outside of the range, so that space efficiency in an inner portion is high. In the present invention, a gear of a fixed gear fixed at a seat cushion is formed in only a portion in the circumferential direction, and a portion at which the gear is not formed is a sliding surface. One of teeth among a plurality of teeth of a pinion of a revolving gear is short, to form a notched tooth portion. In a state in which the forward-collapsed angle of a seatback exceeds a predetermined angle, the notched tooth portion faces the sliding surface and the revolving gear body no longer rotates. At this time, since a bracket at which a sensor ball is mounted also does not rotate, the bracket is held at a fixed position relative to a frame plate.
