项目摘要

Function achieved by this research and development and obtained finding(1) The case of the device became 90 × 135 × 34mm made of a reinforced resin. A first target was judged that the miniaturization more than this was impossible as long as parts which were able to be obtained in general were used though assumed 80 × 120 × 20mm or less. Moreover, the possibility of accomplishment of a goal was abandoned by molding a special case though was because became great cost amount.(2) Continuous operation for 2.5 hours or more was achieved with two AA alkali dry batteries.Operation for five hours or more can be expected by measures of making to the power saving in the future.(3) A temperature, humidity, an illuminance, ultraviolet rays strength, ph, Nox, simple colorimeter, and doses of radiation, the timer, and the counter were achieved as a measurement function. The temperature, ultraviolet rays strength, the illuminance, the timer, the counter, and the stop watch were assumed with built-in the main body among these.(4) The display adopts reflection type LCD of 16 × 2 lines. became an important factor when shape and the size of the display miniaturized the device.(5) The figure key was omitted for the operativeness improvement, and tried for the simplification by the menu selection method and the Japanese guidance function. As a result, the operation key became seven.(6) The cooperation of the personal computer and the printer was achieved by the infrared rays communication. As a result, portability and operativeness have improved.(7) The brightness of the exhaust gas of the car, air pollution, the radiation, food, and the room, health, and ultraviolet rays, the living thing, and acid rain, etc. were developed as a related teaching material.(8) Effective to the collection of basic data for the teaching material this device as the evaluation which had been obtained because of the class which used these teaching materials was clarified.

通过本研究和开发实现的功能和获得的发现（1）器械的外壳变为90 × 135 × 34 mm，由增强树脂制成。第一个目标被判定为，即使假定为80 × 120 × 20mm以下，只要使用通常能够获得的部件，就不可能实现比这更小的小型化。此外，尽管成本很大，但通过成型特殊外壳来实现目标的可能性被放弃。(2)使用2节AA碱性干电池可连续工作2.5小时以上，今后通过采取节电措施，预计可连续工作5小时以上。(3)温度、湿度、照度、紫外线强度、ph、Nox、简易色度计、辐射剂量、计时器和计数器作为测量功能。温度、紫外线强度、照度、计时器、计数器和秒表都是内置在主体中的。(4)显示器采用16 × 2线反射式LCD。当显示器的形状和尺寸使装置小型化时，(5)为了提高操作性，省略了数字键，并尝试通过菜单选择方法和日语引导功能来简化。于是，操作键变成了七。(6)通过红外线通信实现了个人计算机和打印机的协同工作。因此，可移植性和可操作性得到了改善。(7)开发了汽车尾气亮度、空气污染、辐射、食物、房间、健康、紫外线、生物、酸雨等相关教材。(8)该装置有效地收集了教材的基本数据，作为对使用这些教材的班级的评价。
