Abstract: PURPOSE:To prevent clogging of a header by providing a liquid supply port and a discharge port in a manner as to produce liquid flow in parallel to header faces and partly circulating supply liquid in a method of supplying colloidal raw liquid to the inside surfaces of hollow yarn membranes and filtering and concentrating the same. CONSTITUTION:Colloidal raw liquid such as paints, soy source, liquor, emulsion, latex, and suspension of pigments etc. is supplied to the membrane inside surfaces of the hollow yarn 4, 4' of a module bundled with hollow yarn, whereby it is filtered and concentrated. The raw liquid is sent by a liquid feed pump 9 from a raw liquid tank 8 into a raw liquid supply header, in which it produces the liquid flow parallel to header faces 3, thence it enters through a raw liquid supply port 2, which is so formed as to wash the header faces 3, and comes out from a raw liquid discharge port 5, thereby returning to the raw liquid supply side through a circulating circuit 10. Part of the raw liquid flows into hollow yarn 4, 4', and is thereby treated. This liquid returns to the raw liquid supply side by flowing through a raw liquid discharge header 6. The penetrated liquid goes out from a filtrate outlet 7. Thus, the header faces which are most likely to be clogged are washed and will no longer clog.

Title: Fluorescent-x-ray analyzing apparatus
Inventor: KOMATSU SHIGEMI
IPC: G01N23/223
Filed: 1983-09-20
Abstract: PURPOSE:To broaden the measuring range of elements in a sample and to improve detecting sensitivity and analyzing accuracy, by using an alloy target for an X ray tube, obtaining a specified wavelength by a spectroscopic crystal plate, and thereafter projecting X rays on the sample. CONSTITUTION:An alloy of heavy metal is used as an anode target of an X ray tube 1. The generated primary X rays X1 are inputted to a spectroscopic crystal 3 at an angle theta through a solar slit 2, and only the specified wavelength is reflected. Then the spectroscopic X rays X2 can be set at an arbitrary wavelength by the angle theta. Thus a monochromatic color is formed. Then, the spectroscopic X rays X2, which are made to be the monochromatic color, are projected on a sample 6 through a solar slit 5. Elements in the sample are excited, and the characteristic X rays for each element is generated. Fluorescent X rays X3 are detected by a detector 8. Energy is divided by a system 9, and the qualities and quantities of many elements are determined. In this way, sensitivity is improved, background of the fluorescent X rays X3 become less at the same time, and the detecting limit is improved. Analyzing accuracy is also improved.

Title: Charge coupled device and driving method thereof
Inventor: ODA HIDETSUGU
IPC: H01L29/76
Filed: 1985-08-06
Abstract: PURPOSE:To provide a charge coupled device having high signal detecting sensitivity and good S/N ratio, by forming a second semiconductor region with at least a portion just below the semiconductor diffusion layer cut away, and by making its impurity concentration lower than that of the main section of the device. CONSTITUTION:A first P well region 15 just below the floating diffusion layer 5 has a lower impurity concentration as a whole than the P well region of the device main section. A backward bias voltage VSUB is applied between the P well 15 and the N-type substrate 1 sufficiently so that the region 15 just below the floating diffusion layer 5 can be perfectly made a depletion layer. Since the region 15 is lower in concentration than the device main section, it can be easily made a depletion layer. This depletion layer consists of a depletion layer extending toward the P well from the floating diffusion layer 5 and a depletion layer extending toward the P well from the N-type substrate 1 connected in series, to make the width of the depletion layer just below the floating diffusion layer extremely large. Thus the capacitance of the depletion layer just below the floating diffusion layer of this device can be made extremely small, so that improvement of the signal detecting sensitivity and of the S/N ratio can be attained.

Title: Phase-locked circuit
Inventor: ISHIGURO TETSUO
IPC: G09G5/12
Filed: 1994-07-26
Abstract: PURPOSE:To generate a stable reference clock by measuring the time difference between the rise of a high speed clock and that of a horizontal synchronizing signal at the stage of delay elements and outputting the clock which has passed through delay elements whose number of stages corresponds to it. CONSTITUTION:An inputted reference clock 16 successively passes delay elements 11 to generate the clock delayed by a certain time. The logical level of the reference clock 16 at the instant of the rise of a trigger signal 17 is stored in a storage element 12. An edge detection element 13 makes the output active when output patterns of two adjacent storage elements 12 are in the high level in the preceding stage and in the low level in the succeeding stage. A 3-state buffer 14 leads the output or the delay element 11 to an output circuit 15 by the output of the edge detection element 13. The output circuit 15 operates wired-OR among outputs of plural 3-state buffers 14 and leads the result to an output 18. Thus, the output 18 is obtained which rises approximately synchronously with the trigger signal 17 and has the same frequency as the reference clock 16.
