Provided are an information distribution device, system, program, and method that can increase the effectiveness of advertisements. The information distribution device selects advertisements to distribute based on viewer attributes collected while distributing content to a display unit.

Information distribution device, information reception device, system, program, and method

An apparatus including an ultrasonic motor having an electrostrictive element of a stator for driving a rotor thereof; and a microcontroller having a central processing unit (CPU), a built-in memory (ROM) and a pulse generating circuit which generates an pulse output signal which is applied to the electrostrictive element of the ultrasonic motor, wherein the pulse generating circuit comprising a rise setting register, a fall setting register, a phase adjustment data register, a cycle data register, a phase arithmetic circuit, a counter, a 1st comparator, a 2nd comparator, and a pulse generator, wherein the counter starts to count up, incrementing its count value from a count initial value, wherein the cycle data register stores, as cycle data, a count maximum value for the counter to count up to it.

Semiconductor integrated circuit and operation method thereof

It is intended to reduce the amount of computation to be performed by CPU or the required amount of storage space in a built-in memory for timing adjustment of a pulse output signal. A digital multiplying circuit in the phase arithmetic circuit of the pulse generating circuit generates a multiplication output signal by multiplying a phase angle change value in the phase adjustment data register and a count maximum value Nmax in the cycle data register. A digital dividing circuit generates a division output signal by dividing the multiplication output signal by 360 degrees of phase angle for one cycle. A digital adding circuit adds the division output signal and rise setting/fall setting count values and a subtracting circuit subtracts the division output signal from these values. The addition and subtraction generate new rise setting/fall setting count values required to delay/advance the phase by the phase angle change value.

An electronic apparatus includes at least a receiver having a synthesizer section for selecting a receiving frequency and providing an information signal corresponding to the selected receiving frequency, a microcomputer operating on a clock signal for controlling the synthesizer section, and a circuit responsive to the information signal for shifting the clock frequency when the selected receiving frequency is a frequency disturbed by a higher harmonic of the clock frequency, thereby to avoid disturbance of reception of the broadcast signal without requiring undue reduction of the clock frequency.

Microcomputer controlled synthesizer-type radio receiver

Apparatus is provided wherein signals which are reproduced from a record medium and which are supplied to head-phones are selectively attenuated and, concurrently, audio electrical signals produced by a microphone are superimposed onto these attenuated signals. An attenuator is coupled between a record/playback transducer and an amplifier; and a switch exhibits a first condition to short-circuit the attenuator, and a second condition to enable the attenuator to attenuate the signals reproduced by the record/playback transducer and also to superimpose the audio electrical signals produced by the microphone onto the attenuated signals. In one embodiment, a record/reproduce selector selectively establishes either a recording mode, whereby the audio electrical signals produced by the microphone are amplified and supplied to the record/playback transducer, or a reproducing mode, whereby the signals reproduced from the record medium by the record/playback transducer are supplied to the amplifier.

Recording/reproducing apparatus with selective attenuation of reproduced

An operating mode change-over apparatus in a tape recorder includes: a plunger-solenoid having a stationary iron core and a movable iron core movable from a first position in contact with, and a second position spaced from, the stationary iron core; an electric motor; a pinion driven by the electric motor; a rack engageable with and disengageable from the pinion; an operating mode change-over member driven by the rack; a locking lever driven by the movable iron core and holding the engaged condition of the rack and pinion; and a spring for pressing the movable iron core to the stationary iron core, wherein, while the movable iron core is pressed to the stationary iron core, the plunger-solenoid is energized, and the electric motor is driven.

Operating mode change-over apparatus in tape recording and/or

A multi-cavity klystron device having a plurality of resonance cavities, comprising a plurality of movable elements, each of which is mounted on each of said resonance cavities and which is adapted to change the resonance frequency in each cavity, a plurality of tuning means for giving a reciprocal movement to each movable element against a resilient member provided therefor, a plurality of pulse motors coupled to the tuning means, and a preset means for controlling pulse supply to each pulse motor, wherein a predetermined number of pulses stored in the memory units of the preset means are selectively applied to the pulse motors to rotate each pulse motor in correspondence with the number of pulses, thereby changing each resonance frequency of each cavity.
