Self-regulating electrical heating systems which comprise a constant voltage or constant current power supply and at least one heating unit which comprises a reactive component, a resistive heating component, and a temperatureresponsive component. Preferably the reactive component and the temperature-responsive component are combined in the form of a capacitor comprising a dielectric whose dielect...

A device for transferring a substance from a vessel (17) by means of a transfer member provided with an axial passage, e.g. a tube (14) or a cannula (26), one end of which is connected or connectable to an opening of the vessel. The device comprises that it comprises two sealable plastic bags (10,22), one of which (10) is intended to enclose the vessel (17) and said one end of the transfer member ...

A distance measuring apparatus of the present invention converges the reflected light on objects through a converging lens and detects the light by a multi-divisional photodiode. The multi-divisional photodiode comprises a plural number of light receiving elements so that each of the light receiving elements detects the reflected light from the corresponding object to provide an electric signal ac...

PURPOSE:To obtain an electronic device in which applied quantity of gold can be reduced while bondability and the like are maintained by a method wherein a barrier coating film made of chrome or its alloy or cobalt alloy is applied to a copper system lead frame and a surface coating film made of material which has excellent bondability is applied to the barrier coating film. CONSTITUTION:A lead fr...

PURPOSE:To improve moisture resistant properties by a method wherein after a metal coating film is applied to a lead frame, the parts of the coating film at least corresponding to outer edge parts of a package are compressed. CONSTITUTION:A lead frame 2 is formed solidly from a thin plate by a punch- press work and a 42-alloy thin plate is employed as its base material 6. A plated copper film 7 as...

In a system having an electronic controller for internal combustion engines, particularly injection engines in which the controller is functionally connected to a plurality of sensors and at least one actuator, the controller is part of an assembly which furthermore comprises a throttle-valve arrangement, an air-mass sensor and a throttle-valve position sensor. In systems with central injection, t...
