Abstract: A signal transmitter for a filling level sensor has two sliding contacts which are manufactured integrally with a holder and with spring elements. This leads to the manufacturing costs of the signal transmitter being particularly low. The sliding contacts are arranged on spring tongues and are connected to one another via a link. The spring tongues and the spring elements are therefore arranged in a row and allow the sliding contacts to be prestressed particularly uniformly against sliding tracks of the signal transmitter.

Abstract: An object is to provide a lighting apparatus the cost of which is low, which is excellent in terms of heat dissipation capacity, and which does not make a human get burned even in the case where the human directly touches the lighting apparatus. An LED substrate unit (1) is mounted on a metal heat conduction plate (3) with high heat conductivity. Resin heat radiation plates (4, 5) with high thermal emittance and low heat conductivity are adhered to the entire exposure surface of both surfaces of the heat conduction plate (3) except for a portion on which the LED substrate unit (1) is mounted. Thus, a three layer structure is formed of the heat conduction plate and the heat radiation plates provided on both surfaces of the heat conduction plate. Heat discharged from the LED substrate unit (1) is diffused in the heat conduction plate (3) and transmitted to the resin heat radiation plates (4, 5), and the transmitted heat is discharged from the resin heat radiation plates (4, 5) to outer air.

Abstract: In a mobile phone (1) that is changeable to a plurality of styles, when connecting a call in response to an originating call or an incoming call by a wireless communication section (14), a central control section (11) controls a style detecting section (24) to detect a current style, and judges whether or not the call should be restricted by referring to an operation mode information storage section (M5). The central control section (11) then restricts the call based on this restriction judgment result and the detection result from the style detecting section (24). Also, the central control section 11 drives a notifying section (20) to give a notification indicating that a call in a certain style is restricted.
