Title: Semiconductor integrated circuit for communication and radio communication system
Inventor: HAYASHI NORIO
IPC: H04B1/40
Filed: 2002-11-21
Abstract: <P>PROBLEM TO BE SOLVED: To provide a semiconductor integrated circuit for communication with a built-in oscillation circuit, which allows a user to choose an external component for the reference oscillation circuit freely between a piezoelectric transducer or an oscillation module without increasing the number of external components or terminals.  <P>SOLUTION: In the semiconductor integrated circuit, two external terminals (P1, P2) are arranged to correspond to the oscillation circuit. One external terminal (P1) is connected to the control terminal (base terminal) of a transistor (Q1) composing the oscillation circuit to make a passage for feeding part of the output of the transistor (Q1) back to the control terminal (P1), thereby making a composition for oscillation. The other external terminal (P2) is connected to a power source voltage terminal via a resistance element (R2) having a high resistance value. Capacitance elements (C1, C2) are connected between the external terminals (P1, P2). When a piezoelectric transducer is connected to the external terminal (P1), the external terminal (P2) is kept at a constant electric potential. When an electronic component for oscillation (oscillation module) is connected to the terminal (P1), the terminal (P2) is kept open.  <P>COPYRIGHT: (C)2004,JPO

Title: Power unit
Inventor: ASANUMA KAZUO
IPC: G05F1/46
Filed: 2002-11-26
Abstract: <P>PROBLEM TO BE SOLVED: To provide a power unit which is stable and is possible of high-speed response.  <P>SOLUTION: To perform PID feedback control in a power unit, there was hitherto necessity to provide a gain margin and a phase margin, in the Bode diagram of a loop transfer function. The controller of this power unit is a circuit which realizes such a transfer function as to provide a section 81 where the decrease of gain is heavy and a section 82 where the phase delays greatly, securing only a phase margin without securing a gain margin, with the value of each coefficient being different though the form of the transfer function is the same as before. This is realized by applying the integration element of PID as far as a frequency region higher than the resonance frequency of an LC filter. Hereby, high-speed response becomes possible without marring the stability. Moreover, the difficulty never increases as regards the setting of a circuit constant.  <P>COPYRIGHT: (C)2004,JPO
