A portable device for noninvasively treating Meniere's disease and similar conditions by introducing pressure pulses into an ear canal to vibrate auditory ossicles through a tympanic membrane. The device includes a pump unit for generating the pressure pulses, wherein the pump unit includes a Voice Coil Motor and a diaphragm pump that is driven by the Voice Coil Motor; an earpiece for transmitting the pressure pulses to a tympanic membrane; a controller for controlling the pump unit; and an alarm lamp. When the device detects no pressure pulses being generated even when the pump unit is operated, the alarm lamp is lit and an error message is displayed on the indicator, and when the device detects the earpiece being disconnected from the ear of the user, the microcomputer stops counting the time elapsed and the alarm lamp is lit and an error message is displayed on the indicator.

A receptacle connector prevents a plug from being obliquely inserted with a simple configuration. Receptacle connectorhas: a hollow rectangular shape shield case () which is made by machining a metal plate and which includes fitting slot; and a housing () which is covered by the shield case () and in which contacts () to be connected with terminal parts () of an inserted plug () are disposed. In the shield case (), a projecting part () is formed extending along one side of the fitting slot () by denting an upper plate part (), which defines the accommodating part () accommodating the plug (), to project toward an accommodating region (). An end surface () of this projecting part () on the fitting slot () side is closer to the fitting slot () side than the contacts () and forms a plane orthogonal to the upper plate part ().

Connector for data conversion

A cooling system for a motor is prevented from exhibiting a thermal fatigue failure due to a temperature cycle. The operation or stopping of the cooling motor fanof the forced cooling system is controlled using the difference between the temperature thereof and the operation start temperature Tis of the power converter. Thus expansion of the temperature range is suppressed.

A rotary electric machine having improved coil connection reliability, simplified coil end processing steps and improved workability based on an improved components mounting method is to be provided. Flat type conductors are inserted in a stacked state into each of slots formed in a stator core, and a side face of a preceding-stage winding terminal end and a side face of a succeeding-stage winding start end in the flat type conductors are lapped and connected to constitute an assembly of stator coils. The stator coil assembly comprises plural coil groups, and one electrode is connected to one conductor end in the coil groups, while another electrode is moved in a successive manner to connect preceding- and succeeding-stage winding terminal and start ends of the conductors. Further, an insulating ring with crossover conductors laid thereon is combined with such stator coil assembly to connect winding terminal and start ends of the stator coil assembly, thereby constituting a predetermined winding circuit.
