Title: Disc record reproducer
Inventor: NOGUCHI YUTAKA
IPC: G02B7/28
Filed: 1984-12-19
Abstract: PURPOSE:To eliminate the working sounds of a pickup by using a means which controls the servo gain of a high range of a focus servo means in response to the voltage detected by a means which detects the voltage (focus residual noise) applied to a focus actuator. CONSTITUTION:The AC component of the focus residual noise is supplied to a comparator 22 via a capacitor 18, diode 19 and a time constant circuit 20. If the level of the focus residual noise is higher than the reference voltage of a constant voltage power supply 21, the signal at an H level is outputted and supplied to the gate of a gain control FET14a via a diode 23 and a resis tance 24. Then the internal resistance of the FET14a is reduced and the voltage dividing ratio produced by a gain control resistance 14b is increased. Thus the gain of a focus servo circuit 11 is reduced. While the output of the compara tor 22 is set at an L level when the level of the focus residual noise is lower than the reference voltage of the power supply 21. Then no output is applied to the FET14a owing to the presence of the diode 23.

Title: Mass-spectrograph for laser ionized neutral particle
Inventor: AZUMA YASUHIRO
IPC: H01J37/252
Filed: 1992-10-07
Abstract: PURPOSE:To reduce the sensing limit concentration by using all produced photo- excited ions through utilization of all laser pulses. CONSTITUTION:In synchronization with light emission of ultraviolet pulse laser, voltage is swept on a scanning electrode in the X-axis and Y-axis direction. Thereby the time required for an ion beam to make one run of scanning over a region to be analyzed is made equal to the light emitting interval of the pulse laser, and it is so arranged that the ultraviolet pulse laser is cast onto neutral particles produced from the central part of the ion beam irradiation region. Concretely, if the repetitive frequency of ultraviolet pulse laser is represented by (f) and the number of scanning lines by (n), sawteeth voltages of f-Hz and nxf-Hz are swept on the scanning electrode in the X-and Y- direction. Thereby the ultraviolet pulse laser makes light emission only when the ion beam comes to a certain position in the region to be analyzed, and the phase of the laser light emission is adjusted so that light emission takes place (t) sec, after sputtering. Thereby only the neutral particles from the central part which is flat can be ionized and sensed as photo-excited ions, which allows enhancing the resolution in the depth direction and improving the sensitivity.

Title: Image processor
Inventor: ONEDA SHOGO
IPC: G06T9/00
Filed: 1998-09-22
Abstract: PROBLEM TO BE SOLVED: To decrease a capacity of a prepared memory and to enhance the processing time and the image quality or the like within the prepared memory capacity. SOLUTION: A companding section 107 selects a variable length compression system to compress an output image at a high compression rate in the case of compressing the output image whose size is larger than the size A4, selects a fixed length compression system because rotation of the image should be considered when the size of the output image is smaller than the size A4, and applies no compression to the image when the output image is not compressed and its size is so smaller that it can be stored in a memory 108. An area separation result companding section 103 and an edit information companding section 110 select the variable length compression system in the case of compressing an output image whose size is larger than the size A4 and do not entirely compress the area separation result and edit information when the size of the output image is less than the size A4.
