Patent JP-H09182427-A (JP)
Title: Self-oscillation-type dc-dc converter
Inventor: YAMASHITA NOBUHIKO
IPC: H02M3/338
Filed: 1995-12-20
Abstract: PROBLEM TO BE SOLVED: To obtain the stable operation in a broad operating range and to suppress the loss caused by useless feedback by connecting a variable capacity element between the drain and the gate of a MOSFET. SOLUTION: In a self-oscillation-type DC-DC converter 200, when the control voltage by a control voltage source 3 becomes high, the applied voltage to a variable capacity diode 11 becomes high. Then, the applied voltage of a variable capacity diode 72 becomes low conversely when the applied voltage to the variable capacity diode 11 becomes high since the voltage across the drain and the source of a MOSFET 1 is constant. In this way, the control is performed so that the feedback capacity is decreased with the increase in gate capacity. That is to a say, since the feedback capacity is made variable by connecting the variable capacity element 72 between the drain and the gate of the MOSFET 1, the value of the feedback capacity can be changed with the change in capacity of the gate capacity. Thus, the stable operation can be obtained in the operating region in the broad range.

Inventor: REIMANN CHRISTIAN
IPC: G05G1/44
Filed: 1998-12-15
Abstract: PROBLEM TO BE SOLVED: To provide a pedal which has an extremely simple constitution and also requires a very small space. SOLUTION: This pedal 14 consists of a pedal arm 3 which is previously loaded at its basic position by a return spring element 12 that is rotatively supported as a leg-spring 11 and a friction body 15.

Abstract: PURPOSE:To detect a peak point accurately and to perform calibration accurately by using the line obtained from the detected peak. CONSTITUTION:When dark density is changed into bright density on the scanning line of an image or when bright density is changed into dark density, the density difference (¦fxi+1-fxi-1¦) between neighboring picture elements with respect to noted picture element is obtained. The point, where the density difference becomes the maximum value, is made to be the peak point. The calibration data are formed by using the peak point, which is detected as described above. When the density is changed on the scanning line as bright, dark and bright or dark, bright and dark, the height of the density is set so that a point 113 or 114, where the density becomes maximum or minimum, is made to be the peak point. The calibration data are prepared based on the peak point.

Filed: 1992-11-05
Abstract: PURPOSE:To irradiate the entire area to be measured of a sample with light at the same illuminance with a simple mechanism by rotating a prism inserted into the middle of an irradiating luminous flux. CONSTITUTION:A prism 4, the rotation axis of which is made coincident with the optical axis K of an optical system, is held in a rotatable state by means of the rollers 5A-5C of a driving section 5 and rotated when the roller 5C is rotated by means of a motor 5D. An encoder 5D detects the rotational position of the prism 4 and sends the detected position to a CPU 8. A luminous flux condensed through a lens 3 so that the luminous flux can irradiate a required area around the optical axis K on the surface of a sample S irradiates a point deviated from the center of the optical axis K after passing through the prism 4. When the prism is rotated around the optical axis K, the irradiating spot P rotates around the center of the optical axis K and randomly reflected light rays from the surface of the sample S are detected by means of detectors 6 and sent to the CPU 8 after amplification 7. The CPU 8 integrates and averages the outputs of the detectors 6 at every rotation based on the signal from the encoder 5E and a displaying section 9 displays the processed results of the CPU 8.
