摘要： PURPOSE: To improve reliability of the defrosting operation of a heat pump type air conditioner, by using as a frost detecting element a humidity sensing element that causes negative change of resistance to the change of relative humidity or a dew sensor that causes change in resistance in response to the dewing.
CONSTITUTION: When dew deposits on an element 1 during operation of an air conditioner, the value of resistance of a dew sensor is increased, and output voltage V of a resistance-voltage converting circuit 2 becomes higher than a first reference value V
1 . At the same time, a defrosting operation starting signal is produced from a first comparison circuit 13 and maintained in a holding circuit 7. Subsequently, when defrosting of the element 1 is completed by defrosting operation, the value of resistance of the element 1 is lowered and output voltage V of the resistance-voltage converting circuit 2 becomes lower than a second reference value V
2 . Resultantly, a defrosting operation stopping signal is produced from another comparison circuit 5 and the holding circuit 7 is reset. With such an arrangement, it is enabled to enhance the reliability of defrosting operation.

摘要翻译：目的：为了提高热泵式空调的除霜运转的可靠性，通过使用作为结霜检测元件的湿度感测元件，其导致相对湿度变化的阻力变化的阻力变化或导致电阻变化的露点传感器回应呕吐。构成：在空调机运转时，当元件1露出时，露点传感器的电阻值增大，电压 - 电压转换电路2的输出电压V变得高于第一基准值V1。同时，从第一比较电路13产生除霜运转启动信号并保持在保持电路7中。随后，当通过除霜操作完成元件1的除霜时，元件1的电阻值降低并且电阻 - 电压转换电路2的输出电压V变得低于第二参考值V2。结果，从另一比较电路5产生除霜运转停止信号，复位保持电路7。通过这样的配置，能够提高除霜运转的可靠性。

摘要： PURPOSE:To enable the change-over of a flow path and the control of flow quantity by current controlling, by means of setting up a movable iron core receivable concaved part at top end part of a fixed iron core, and of forming the outer end circumference of the top end of the fixed iron core into a taper part of a tapering- shape. CONSTITUTION:A movable iron core receivable concaved part 9 is set up at the top end part of a fixed iron core 8, and the outer circumference of the top end of the fixed iron core 8 is formed into a taper part 18 of a tapering-shape. By such means, when the movable iron core 5 is absorbed to the side of the fixed iron core 8 by means of energyzing the electromagnet 7, the absorbing power becomes constant corresponding to the current value after the movable iron core being proceeded into the concaved part 9 of the fixed iron core 5. Accordingly, the spool 2 can be positioned at a prescribed position corresponded to the current value, and the change- over of a flow path and flow quantity control can optionally be performed by current controlling.

摘要： PURPOSE:To improve the workability and enable accurate and easy tracing control by eliminating the phase deviation between the aiming positon of welding torch and detecting position of tracing sensor, by providing a tracing sensor in a position spaced from the target weld line. CONSTITUTION:A welding torch 6 is pivoted on the tip of a turning shaft F which is revolved by a motor 13 in a manner swingable in the vertical plane. By the electrical displacement of a potentiometer 8 for Z, the height and aiming angle of the welding torch 6 are judged. By the composition of three electrical displacements of potentiometers 10, 12, 14 for X, Y and F, the relative position of the welding torch 6 with respect to a work 1 is judged. Correction commands to Z-axis, X-axis and Y- axis are issued from both tracing sensors 5 and 17, and the welding torch 6 is directed at a specified aiming angle with respect to the weld line l which composes a three-dimensional curve.
