Abstract: In a cylinder discrimination device in an engine, a crank angle signal is output for each unit crank angle in synchronization with the rotation of a crankshaft in the engine, different numbers of cylinder discrimination signals are output corresponding to cylinders to be discriminated during a predetermined crank angle period, and a count value of the crank angle signals to be output after a cranking start is held each time the cylinder discrimination signal is output. By comparing the count value of the number of the crank angle signal outputs at a first cylinder discrimination timing with the past count values, to detect the number of the cylinder discrimination signals output during the predetermined crank angle period, and first cylinder discrimination after the cranking start is performed based on the number of the detected cylinder discrimination signals.

Abstract: In a variable valve mechanism that changes an opening characteristic of an engine valve by a rotation force of a direct current motor, an electric current to be supplied to the direct current motor is forcibly lowered by providing restriction to a control signal of a power transistor that supplies the electric current to the direct current motor, or providing restriction to a change speed of target value of the opening characteristic, when an engine temperature is high.

Abstract: In the portable telephone of the present invention, a transmission power upper limit value (STEPLIM in accordance with temperature (T) is found (S1, S2), whether the transmission power set value (STEPn) of the next slot exceeds the upper limit (STEPLIM) or not is determined (S3, S4), and when it does not exceed, a control signal value (Vc) in accordance with the transmission power set value (STEPn) is applied to a variable gain block (11, 13) (S5, S7). When it exceeds the upper limit, a control signal value (Vc) in accordance with the transmission power upper limit value (STEPLIM) is applied to the variable gain block (11, 13) (S6, S7).

Abstract: During the time when a radio mobile station is in communication with a base station at a certain frequency, when the frequency is being switched to another frequency and the reception level is being measured, AD data applied to a despreading/demodulating circuit (6) is set to “0” by an A/D output mask control portion (16). Thus, a noise component irrelevant to demodulation is prevented from being input to the despreading/demodulating circuit (6) after a local oscillation signal is output from a PLL synthesizer (4) until a stable baseband signal is output from a mixer circuit (3), so that stable demodulation is ensured.
