摘要： A liquid level indicator for detecting a liquid level by utilizing the variation inductance of a coil having a core made of an electrical insulating magnetic material and provided inside a winding of the coil. The core may be made by piling a plurality of thin, plate-shaped conductive materials one on another in the cross-sectional direction of the coil so that they are insulated from each other or by winding a conductive magnetic material at least one turn in the form of a roll so that a closed loop current is not formed in the cross-sectional direction of the coil. An eddy current loss of the core so arranged is so small that it can be disregarded. Furthermore, the winding component of the core itself is substantially released in the equivalent circuit of the coil.

摘要： In a surface inspection method in which parallel rays passing through a thin slit are projected onto a surface of a specimen and a luminous line formed on the specimen surface by the parallel rays is viewed by a television camera so as to inspect the specimen surface, a photo-electric signal showing the luminous line is picked up from an output video signal of the television camera. The time from rising state of the horizontal synchronizing signal contained in the video signal to occurrence of a pulse of the photo-electric signal is measured in each period of the horizontal synchronizing signal. The time data in each period is compared with a previously set reference value, and whether or not the specimen passes the inspection is discriminated based on variation of the comparison result.

摘要： A horn switch for a steering wheel having an air bag device. The steering wheel includes a multilayer membrane switch as the horn switch in which spacers in one layer are not aligned with the spacers in the other layers. Accordingly, even when the membrane switch is depressed just over one of the spacers in one layer, the electrode plates in the other layers can make contact with each other. Thus the operable area of the membrane switch is enlarged. Further, the membrane switch is supported on its lower surface by a number of ribs which define a number of spaces between the pad lower surface and air bag device. As a result of this space, the operation on the membrane switch can be made resilient in spite of the provision of the air bag device directly under the steering wheel pad. Further, because each part of the pad separated by the air bag device upon impact, each part must be provided with a membrane switch. For this reason, a wiring structure for the two membrane switches is provided such that the manufacture of the pad and the assembly of the steering wheel is more easily facilitated.
摘要翻译： 用于具有气囊装置的方向盘的喇叭开关。 方向盘包括作为喇叭开关的多层膜开关，其中一层中的间隔物不与其它层中的间隔物对准。 因此，即使当膜层开关在一层中的一个间隔物上被压下时，其他层中的电极板也可以彼此接触。 因此，膜开关的可操作区域被扩大。 此外，膜开关在其下表面上被多个肋支撑，这些肋在垫下表面和气囊装置之间限定了许多间隔。 作为这种空间的结果，尽管将气囊装置直接设置在方向盘垫下方，膜开关上的操作可以变得有弹性。 此外，由于垫片在撞击时由气囊装置分隔开，所以每个部分必须设置有薄膜开关。 为此，提供了两个薄膜开关的布线结构，从而更容易地促进了垫的制造和方向盘的组装。

摘要： A microprocessor-based telephone set includes a telephone number memory, a number indicator, an abbreviated number selecting switch, an abbreviated number controller, and a selecting signal controller. The call is made when a selecting signal is sent to a base station. The selecting signal is issued when selecting signal controller retrieves a certain telephone number of a called party according to a displayed abbreviated number on the indicator on receiving a signal controlling the transmission start of the selecting signal. The signal which controls the transmission start of the selecting signal can be generated by means of the same switch that hook-signals. The telephone equipment can be installed on a steering wheel of an automobile.
