Abstract: Provided is a novel compound having BTK inhibitory action and a cell proliferation suppressing effect. Also provided is a medicine useful for the prevention and/or treatment of a disease associated with BTK, particularly cancer, based on BTK inhibitory action. A compound represented by formula (I) [wherein R1 to R3, W, A, Y and Z respectively have the meanings as defined in the specification], or a salt thereof is disclosed.

Abstract: The living body information sensor according to the present invention can be attached to a living body. A light emitting unit emits light to the living body. The light receiving unit receives reflected light from the living body that is included in the light emitted by the light emitting unit to the living body, and outputs a signal according to intensity of the reflected light. A control device generates information about the living body based on the signal from the light receiving unit. The control device controls the light emitting unit to turn on and off in an alternate manner. The control device sets a total of a turn-on time of the light emitting unit in a prescribed time interval to be smaller when the living body information sensor is attached to the living body than when the living body information sensor is not attached to the living body.

Abstract: An input signal is input via a first resistor to an inverting input terminal of an operational amplifier. A second resistor is provided on a feedback path between an output terminal and the inverting input terminal of the operational amplifier. A control voltage Vcnt output from the operational amplifier is input to a VCO. A frequency divider frequency-divides an output signal Sout of the VCO. A phase comparator compares an output signal from the frequency divider with a reference clock signal and outputs a voltage according to a phase difference. A loop filter removes a high-frequency component of an output voltage Vcp of the phase comparator and outputs the voltage to a non-inverting input terminal of the operational amplifier.
