Title: Power supply voltage fluctuation correcting method in pulse width modulation amplifier
Inventor: ISHIKAWA TSUTOMU
IPC: H03F3/217
Filed: 1984-07-31
Abstract: PURPOSE:To eliminate output fluctuation due to power supply voltage fluctuation by detecting the fluctuation of a power supply voltage fed to a power amplifier circuit, converting the detected signal into a digital signal and using the digital signal so as to correct an input signal. CONSTITUTION:When an input signal Sin is an analog signal, a level adjusting circuit 5 adjusts a level of a power supply voltage + or -V fed to a power amplifier circuit 2 from a power supply 4 and detects the fluctuation. That is, the level of a power supply voltage +V is decreased by a DELTAV, the power voltage is set to a level (a) when it is a specified voltage to a sawtooth reference pulse CP so that the upper limit of the expected fluctuation is a level (b) and the lower limit is within a level (c), and the fluctuated voltage DELTAV is inputted to a pulse width modulation (PWM) circuit 6. The PWM circuit 6 applies the pulse width modulation to the fluctuated voltage DELTAV to convert it into a digital signal. That is, the fluctuated voltage DELTAV is compared with the reference pulse Cp to output a signal A of pulse width modulation waveform going to ''H'' only at DELTAV>Cp. The duty of the signal A is selected to 10% at, e.g., the specified voltage so as to attain level adjustment by the level adjusting circuit.

Title: Automatic control circuit for clock phase
Inventor: GOTO HARUHIKO
IPC: H04L7/00
Filed: 1985-07-18
Abstract: PURPOSE:To obtain reproduced data having no deterioration in error rate even when waveform distortion and a phase shift with temperature, etc., are caused by allowing a clock to rise or fall at the optimum point of input data at any time. CONSTITUTION:When a clock rising point is moved from (5) to (4), the level of a BB signal is lower than S1 or higher than S2 in the beginning (namely, between reference levels S1 and S2), so outputs of FFs 67 and 68 are L and H, the output of a OR circuit 9-6 is H, and a variable phase shifter 8 makes a phase shift to, for example, left. When, however, the clock shifts in phase from (2) to (1), the outputs of the FFs 67 and 68 are L and L (namely, outside the reference levels S1 and S2), the output of a OR circuit 69 becomes L and a change in state is caused. The phase shifting direction is inverted to the original direction, but the output state of the OR circuit changes again from (3) to (4), so the phase shifting direction is inverted. Namely, the phase sift of the clock is controlled so that the rising or falling point comes closer to the maximum value of the BB signal.

Inventor: HIGUCHI YASUO
IPC: F16H21/16
Filed: 1999-04-28
Abstract: PROBLEM TO BE SOLVED: To reduce the cost of a coil roller by machining a wire rod of the outside diameter slightly smaller than the coil inside diameter of a cylindrical coil spring into a spiral state, letting the coil spring to pass through the spiral wire rod, and rolling a cylinder outer face and the cylinder inner face concentric with each other. SOLUTION: When a cylindrical coil spring 1 is elastically deformed and allowed to pass through a spiral wire rod 2 of the wire diameter slightly larger than the coil inside diameter and stoppers 7 are attached to both sides, the central axis of the spring 1 can be held in a spiral state so as to be formed into the spiral cylinder coil spring 1. When this is press fitted between a rod 3 and a pipe 4 accompanied with the relative rotation of the both, the spring 1 is assembled in its spirally and elastically deformed state. When the rod 3 and the pipe 4 are rotated relatively in this state, the spring 1 is rolled in the press contact state, and the rod 3 and the pipe 4 are moved relatively and linearly. Conversely, when the rod 3 and the pipe 4 are moved relatively and linearly the both are relatively rotated.  The spring 1 can be thus rolled in a prescribed inclined angle and a roller can be provided at low cost.
