Title: Cleaning method for treating gas supplying system
Inventor: JINNAI SHINPEI
IPC: C23C16/448
Filed: 1995-11-22
Abstract: PROBLEM TO BE SOLVED: To provide a cleaning method for a treating gas supplying system capable of effectively removing a high-viscosity liquid org. metallic material. SOLUTION: This method comprises supplying the high-viscosity liquid org. metallic material 16 to an vaporizing means 28 via a supplying passage 24 to vaporizing the material and to form a treating gas and supplies this treating gas to a treating device 42 to wholly or partially clean the entire part of the treating gas supplying system 14. The supplying passage part to be cleaned is heated in a temp. range where the viscosity of the org. metallic material is lowered and the thermal decomposition of the material does not arise. A purging gas is then passed to the supplying position part to expel the org. metallic material 16 lowered in the viscosity.  An org. solvent which does not react with the org. metallic material is then introduced into the supplying passage part in the lowered viscosity state of the org. metallic material, by which the remaining org. metallic material is dissolved and the supplying passage part is cleaned. As a result, the gas purging is executed in the lowered viscosity state and, thereafter, the residual material is dissolved by the org. solvent, by which the approximately sure expulsion of the org. metallic material is made possible.

Title: Pickup controller
Inventor: SHIMODA YASUHISA
IPC: G11B7/1398
Filed: 1995-11-22
Abstract: PROBLEM TO BE SOLVED: To obtain a high performance pickup controller reading out a signal with a better condition while selectively changing over the shape of plural beam spots by changing a readout condition according to a signal to be read out. SOLUTION: The focusing error signal from a pickup 3 is amplified by a focusing error amplifier 5. When a first off-set signal generator 8 is selected by a switch and the signal is inputted to the focusing amplifier 5, jitters of main signals such as picture, voice and so forth are made smaller by making the shape of a beam spot to be an elliptic shape having a minor axis in a track direction. When a second off-set signal generator 9 is selected, the shape of the beam spot becomes shorter in a direction orthogonal to the track to make the signal to noise ratio of the wobble signal of a pre-groove or the like best. Thus, a satisfactory signal readout is performed corresponding to a disk.

Filed: 1993-12-24
Abstract: PURPOSE:To apply a power supply voltage equal to or higher than the breakdown strength of a transistor TR by setting a voltage applied between the emitter and the collector to a level lower than the power supply voltage when the transistor TR is off. CONSTITUTION:When a first power supply setting circuit 11 is provided and the values of resistors R5 and R6 are equalized, only the voltage which is the half of the power supply voltage is applied between the emitter and the collector of the TRQ1 when an NPNTRQ1 is off. Also when a second power supply setting circuit 12 is provided and the resistors R8 and R9 are equalized, the voltage between the emitter and the collector also becomes the half the power supply voltage when an PNPTRQ2 is off. Thus, the size of the power supply voltage inputted to a power supply terminal 4 can be equal to or high than the breakdown strength value of the TR. Also, the amplification factor of pulse signals from an input terminal 2 can be made large. Further, since this pulse output circuit is constituted of only the TRs and the resistors, it is easily integrated.

Title: Method for producing enclosing convex of digital picture
Inventor: KUBO FUMIO
IPC: G06T7/60
Filed: 1987-12-28
Abstract: PURPOSE:To omit need to obtain centroid coordinates, to perform a real number arithmetic operation and to rearrange the coordinate series and to shorten the processing time by scanning previously a subject picture and obtaining a compressed gathering out of the coordinate series of the subject picture. CONSTITUTION:A binarized picture is scanned in the (x) and (y) axis directions orthogonal to each other on a plane for acquisition of the coordinates where the value changes for each scan line. The same coordinate points are deleted out of the obtained coordinate series for compression of the binarized picture and the continuous three points are chosen out of the compressed picture. In other words, the coordinates (Pxy1, Pxy2) which are set at '1' first and finally respectively are obtained. Then a pair of (Px11, Py11) and (Px12, Py12) and a pair of (Pxm1, Pym1) and (Pxm2, Pym2) extracted from the coordinate series are compared with each other. Then the latter pair is deleted if both coordinates are equal to each other. Thus an arithmetic operation is carried out to a compressed picture for acquisition of enclosing convex and therefore the number of arithmetic points are decreased. Thus it is not required to calculate the coordinates and the real number of the centroid and to rearrange the coordinate series. As a result, the processing time is extremely shortened.
