Patent number: 8384450Abstract: A frequency synthesizer device that includes two modulation paths and suitably adjusts the amplitude of a control voltage that is outputted from a digital-to-analog converter (DAC) to a voltage-controlled oscillator. The frequency synthesizer device is provided with a voltage-controlled oscillator, a programmable frequency divider, a frequency phase comparator, a DAC, a switch and a modulation frequency displacement correction circuit. The voltage-controlled oscillator oscillates at an oscillation frequency depending on an input voltage. The programmable frequency divider frequency-divides a signal from the voltage-controlled oscillator. The frequency phase comparator outputs a phase difference between the frequency-divided signal and a reference clock. The DAC outputs an adjustment voltage. The switch connects the voltage-controlled oscillator to a reference voltage power source at a time of correction of the adjustment voltage.Type: GrantFiled: July 11, 2011Date of Patent: February 26, 2013Assignee: Oki Semiconductor Co., Ltd.Inventor: Takashi Kuramochi

Patent number: 7328272Abstract: A server receives an acquisition request for visual content, such as desired text or image content, from a client terminal via a communication network, and retrieves, from a database, data of the visual content requested by the client terminal. Then, by analyzing the visual content, by referring to an appropriate table or otherwise, the server determines music content or effect tone content to be imparted to the requested visual content in associated relation to specific substance of the requested visual content. Then, the server retrieves data of the determined music content or effect tone content from a database, and transmits the data of the visual content, along with the data of the music content or effect tone content, to the client terminal. On the basis of the data transmitted by the server, the client terminal can not only visually display the requested visual content but also audibly reproduce the music content or effect tone content.Type: GrantFiled: March 28, 2002Date of Patent: February 5, 2008Assignee: Yamaha CorporationInventors: Takashi Kuramochi, Shigeki Akahori
