摘要： PURPOSE:To measure contact position coordinates of a pointing material without hardware reset by updating a non-contact impedance at the time when the non-contact state is discriminated continuously a set number of times and a measured impedance is lower than the non-contact impedance by a set value or more. CONSTITUTION:When something other than the pointing material approaches or comes into contact with a touch panel 1 for a long time, (normally, several tens seconds), the contact state is discriminated continuously a set number M3 of times and the non-contact impedance is updated by a first non-contact impedance updating means 6. The non-contact impedance in this case is gener ally lower than that for contact of the pointing material (normally, a finger). Consequently, contact position coordinates of the pointing material on the touch panel 1 can be obtained. If the non-contact state is discriminated continuously a set number M1 of times by a second non-contact impedance updating means 7, the non-contact impedance is updated. Thus, contact of the pointing material is detected to measure the position coordinates without hardware reset.

摘要： PURPOSE:To prevent the erroneous detection of contact position coordinates due to the influence of a flaw, etc., on a resistance film by connecting a first power source terminal through a resistor to one terminal, connecting a second power source terminal to the other terminal and providing a voltage measuring circuit to measure the terminal voltage of the resistor. CONSTITUTION:For example, the flaw, etc., is attached in a position shown by X on a resistance film 3. The resistance value of the resistance film 3 is made high by DELTARx by the flaw, etc., and goes to be (Rx+R1-x+DELTARx). On the other hand, since the resistance value of a resistor 1 is R0 and fixed, the terminal voltage of the resistor 1 goes to be R0.Vcc/(R0+Rx+R1-x+DELTARX) and it is a reference voltage. Thus, an alarm signal is generated by a voltage measuring circuit 4 and supplied to an MPU and it is informed of the MPU that the resistance value of the resistance film 3 is changed. Thus, before next impedance measurement is started, the MPU can know that the resistance value of the resistance film 3 is changed.

摘要： PURPOSE:To prevent erroneous detection of contact position coordinates due to noise by increasing the time constant of an integrator in a variable oscillator and stopping counting for impedance measurement for a time longer than the time when the output voltage of the integrator is unstable. CONSTITUTION:A timing generator 35 generates a trigger pulse (b) synchonously with a switch element driving pulse (a), and this pulse (b) is inputted to a monostable multivibrator MM 44 to output a pulse (c) in the high level for a certain time Tw, and an oscillation pulse (d) from a variable oscillator 20 is inputted to a counter 46 through an AND circuit 45 for the time TW and is counted. Consequently, a terminal L1 of a touch panel 21 and a terminal R1 are connected to the input terminal and the output terminal of a voltage follower 43 respectively by the first pulse (a), and in this state, the counted value of pulses (d) obtained by the counter 46 is taken into a microcomputer by the rise of the pulse (b). Terminal L2 to Ln are successively connected to terminals of the voltage follower 43 in the same manner to obtain the counted value and an impedance calculated value based on the counted value. The counter 46 stops counting when the pulse (c) is in the low level.

摘要： PURPOSE:To reduce the noise made from a discharge panel to the outside without losing the visibility of the discharge panel, by installing a transparent and low resistance conductive membrane on almost all the surface of a substrate at the outer side of an electrode device of the discharge panel, and grounding the conductive membrane. CONSTITUTION:To a substrate 11 of the first electrode device 10, a transparent conductive membrane 40 is spread and furnished. As the transparent conductive membrane 40, an indium tin oxide InSnOx, that is so-called ITO, is used. The ITO membrane 40 is grounded. Thereby, the noise to the upper side U is grounded and not released or little released to the outside Zx. On the other hand, since the ITO membrane 40 is transparent, it gives no influence to the visibility of the generation of the gas discharge. The substrate 21 side of the second electrode device 20 may also be coated with the ITO membrane. When it is coated, the noise to the down side D is grounded in the same manner and not released to the outside. However, it is generally allowable that the discharge panel can be visible only from one direction. Therefore, the second electrode device 20 side may be covered with a metallic shield plate usually.

摘要： PURPOSE:To prevent the deterioration in S/N characteristics, by making the width of ionizer of an atomic beam detector widest at its center part where the temperature most easily rise making the width narrower at the nearer parts to both ends where the temperature is not easy to rise, and making the resistivity change locally. CONSTITUTION:The width of an ionizer 31 in the form of a ribbon is made widest at the center part where the temperature most easily rise, and made narrower at the near parts to both ends where the temperature is not easy to rise because of thermal diffusion to the both sides of connection terminals 32a and 32b. In such a structure, a resistivity changes locally. Consequently, a heat generation at the time of heating increases in accordance with approach to the both ends, so that the lack of uniformity of heating temperature distribution due to thermal diffusion is compensated. This makes it possible to make the heating temperature distribution of the ionizer 31 uniform, and the heating temperature of the ionizer 31 can be suitably set to a specified value. The temperature distribution of the ionizer 31 is made uniform, the deposition or revaporization of Cs atom is prevented, the deterioration of S/N characteristics is dissolved, and accuracy and stability of resonance frequency are improved.

摘要： PURPOSE:To prevent the flowing of liquidified Cs to the outside of an atom beam radiation part through a collimator by providing penetratingly a thin tube flowing a beam source vapor to the minute pierced part of a barrier plate between a beam source storage part and an atom beam radiation part in a form that both ends are projected respectively from the face of the barrier. CONSTITUTION:A barrier plate 25 is provided between the beam source storage pat 24 and the atom beam radiation part 29 and the thin tube 41 through which the beam source vapor flows is provided penetratingly to the minute hole pierced part of the barrier plate 25 in a form that both ends are projected respectively from the said barrier wall face. In flowing the Cs in the said Cs ample 21 liquidified by the heat conduction from the atom beam radiation section 29 into the beam source storage part 24, the liquidified Cs is vaporized by the barrier plate 25 heated by the heater 27 of the heat part 29. The Cs vapor passes in the flowing thin tube 41 provided penetrated in a form to be projected to the said barrier plate 25 and is radiated through the collimator 28 as the Cs atom beam 33 to the cavity resonator. Thus, it is prevented that the liquidified Cs 22 flows into the tube 41 due to vibration or shock.
