摘要:
Communication equipment that is provided with an isolating switch, which is operated by placement of a handset, instead of a conventionally used insulating component. The isolating switch constitutes an electrical insulation between a charging, terminal of a base unit and an external electric circuit. This structure eliminates the necessity of providing an insulating component such as a transformer and the like, so as to achieve a cost reduction of the communication equipment, and also improves sound quality of the communication equipment. In addition, the isolating switch is arranged in Such a manner that a direction of tile force applied by the handset to depress the terminal of the base unit and a direction of the force applied by the handset to depress a switch level are separated from each other. The isolating switch has a construction that enables the switch lever to function with a small loading weight, and to keep a contact point of the switch depressed by an intense force. As a result, reliable operation of the switch is attained without increasing, the weight of the handset, since the is available weight of the handset can be utilized efficiently. Further, a mechanical structure for fixing the position of the handset can be eliminated, so as to simplify the overall structure of the communication equipment.

Firstly, the following check chip is set up into a heater: A check chip onto which a sample has been picked up by wiping out the surface of a check target, or a check chip formed by absorbing and collecting the sample into a filter. Here, the filter has been set up in a vibration-type or heating-type portable-type absorption probe in an attachment/detachment-capable manner. Secondly, a sample gas generated from the heated check chip is analyzed using a tandem-type mass spectrometer. This makes it possible to simplify the sample pick-up from various types of check targets, and to shorten the pick-up time and the checking time.

A coming and going personnel control system having a high security level by prohibiting a coming person who has dealt with a dangerous substance from entering a facility through a control area is disclosed. Whether a person coming into the control area carries a dangerous substance such as explosive material with him or has dealt with such dangerous substance can be checked by the steps of: ionizing air which has been contacted with the person coming into a control area by a discharging device; the ionized air is detected by a mass spectrometer as a molecular weight; the molecular weight is input into a control processor; and if the detected molecular weight is matched with a molecular weight of dangerous substance which have been registered previously into the control processor, the door in a direction forward to the coming person is closed.

A hazardous material detection system that can suppress occurrence of contamination due to ionization. When a sensor detects that a test sample has entered an inspection region of an X-ray inspection device as a belt conveyor moves, a corona discharge power supply in a hazardous material detection device is turned on for a constant time, to introduce a gaseous sample containing a substance stuck to the test sample into the hazardous material detection device via a sucking section and gaseous sample introduction piping, in order to ionize the gaseous sample and analyze it at an analyzer, based on a result of which analysis, a data processor decides whether the gaseous sample contains a hazardous material, to display a decision result on a screen. When the test sample is detected by an exit side sensor, the corona discharge power supply is turned off.

Provided are a light source evaluation device, a light source adjustment system, a light source evaluation system, and a light source evaluation method whereby it is possible to evaluate the characteristics of a solar simulator, which is a light source for measuring the characteristics of a solar cell, without creating a reference cell or pseudo cell tailored to the spectral sensitivity of a solar cell to be measured. Said evaluation is performed by calculating an evaluation value of the characteristics of the light emitted by a solar simulator in comparison to natural sunlight on the basis of the spectral irradiance of the light emitted by a solar simulator as measured by a spectroradiometer, the spectral irradiance of natural sunlight, and the pre-measured spectral sensitivity of the solar cell to be measured.
摘要:
Pickup coils which generate vehicle wheel speed signals which include vibration frequency components of tires during vehicle cruising are provided. An electronic control unit extracts resonance frequencies of tires from the vehicle wheel speed signals and estimates tire pneumatic pressure based on the extracted resonance frequencies. When an estimated vehicle wheel pneumatic pressure falls below a predetermined critical pneumatic pressure, pneumatic pressure decline warnings are generated and displayed by a display unit. An update switch is provided and when this update switch is turned on when replacing tires, the electronic control unit adjusts and sets the value of the critical pneumatic pressure described above based on the resonance frequency extracted during this time.
