摘要:
In a lead frame board, while a heat radiation wall member formed by a resin having a relatively high thermal conductivity is provided in a low heat-resistance heat generating component mounting region where a low heat-resistance heat generating component is mounted, heat block wall members formed by resins having relatively low thermal conductivities are provided in a high heat-resistance heat generating component mounting region where a high heat-resistance heat generating component is mounted and in a non-heat generating component mounting region where a non-heat generating component is mounted. Thus, heat block is performed between the low heat-resistance heat generating component mounting region and the high heat-resistance heat generating component mounting region and non-heat generating component mounting region, and a heat radiation function is enhanced in the low heat-resistance heat generating component.

A depth of interaction detector with uniform pulse-height comprises a multi-layer scintillator obtained by coupling at least two scintillator cells on a plane and then stacking the planar coupled scintillator cells, in layers, up to at least two stages and a light-receiving element connected to the bottom face of each scintillator cell of this multi-layer scintillator, wherein the detector is provided with a means for discriminating the position of a scintillator cell, which receives radiant rays and emits light rays and a means for making, uniform, the quantity of the light emitted from each scintillator cell and received by the light-receiving element. The detector can provide precise detection information even when radiation is absorbed by and emitted from a scintillator layer positioned above the scintillator layer optically coupled to the light-receiving element, permits the production of a depth of interaction detector having a three-dimensional depth of interaction-detecting function and can provide the same total output signal, which is independent of the position or a specific scintillator cell practically emitting light if the radiation energy is identical.

摘要:
In an engine idling speed control system for an internal combustion engine, by feedback controlling increasingly or decreasingly, the amount of intake air fed to the engine with a controlling value variable in accordance with a difference between an actual engine speed and a desired idling speed so as to control the engine to drop speed to the desired idling speed, decreasing variations of the controlling value are restricted to a limit value which is higher when the vehicle is running at a speed higher than a predetermined vehicle creeping speed than when at a running speed lower than the predetermined vehicle creeping speed.

A radio transmitter includes a signal processing circuit splitting a basic modulating signal into first and second modulating signals and outputting the first and second modulating signals. A PLL decides a fundamental wave. A VCO forms a portion of the PLL and modulates the fundamental wave decided by the PLL in accordance with a voltage of the first modulating signal outputted from the signal processing circuit. A PLL circuit forms a portion of the PLL and varies a frequency division ratio to modulate the fundamental wave decided by the PLL in accordance with the second modulating signal outputted from the signal processing circuit.
