Title: Preventive of influenza virus infection
Inventor: SHIMAMURA TADAKATSU
IPC: C07D311/62
Filed: 1989-09-14
Abstract: PURPOSE:To provide the subject preventive of influenza virus infection containing tea as the active component, free from side effects and effective in a low concentration. CONSTITUTION:Tea or polyphenols in tea, i.e., catechins of formula I (R1 is H or OH; R2 is H, formula II) in tea and terflavins of formula III (R3 and R4 are H, formula II) in tea are blended as the active components. The above- mentioned active component compounds can deactivate the activities of hemagglutinin and neuraminidase and can prevent infection of influenza virus to cells. By treating virus or cells with the above-mentioned compounds, the infection-preventive effect is shown. In addition, the effect is not limited as in vaccines because antigenicity is not utilized.

Title: Third rail measuring apparatus
Inventor: YOSHIKAWA KENICHI
IPC: G01B11/14
Filed: 1992-09-04
Abstract: PURPOSE:To enable non-contact measurement of a gap between a third rail and an upper protective plate to be simply and highly accurately carried out by performing a scanning with a laser beam radiated from a laser distance measuring device toward the third rail from the side of a vehicle to be inspected and in the longitudinal direction sequentially. CONSTITUTION:A laser distance measuring device 21 mounted on a vehicle 20 to be inspected radiates a laser beam B to a subject in a pulse manner and a distance to the subject is measured from time spent until the reflected beam is received. A rotary mirror 22a reflects the beam B rotating from the distance measuring device 21 to turn the beam to the third rail 1 from the side of the vehicle 20 to be measured while a scanning is performed vertically by the beams B. An arithmetic device 24 calculates a gap L between the rail 1 and the protective plate 6 based on distances to an upper protective plate 5 and rear side protective plate 6 and the rail 1 from the distance measuring device 21 as measures with the distance measuring device 21 while a gap G between the rail 1 and the protective plate 5 is calculated.

Title: Method for detecting flow rate and gas flowmeter
Inventor: KUMAGAI MINORU
IPC: G01F1/00
Filed: 1998-08-24
Abstract: PROBLEM TO BE SOLVED: To correctly measure a flow rate of a fluid by converting an output value of a sensor to the flow rate by a calibration curve of quadratic or higher degrees formed by the method of least squares. SOLUTION: A calibration curve is formed into quadratic or higher degrees by the method of least squares, whereby an optimum approximate expression is obtained. A sufficient accuracy cannot be obtained in flow rate values in the calibration curve of a linear approximate expression. Although the accuracy is good as a degrees increases in the expression of quadratic or higher degrees, the expression becomes complicate and disadvantageously increases a burden to a calculating means. Therefore, the expression of 3-6 degrees is preferred. In a method whereby each coefficient of the expression is determined with the use of an expression of a preliminarily determined high degree (n) without using the method of least squares, the accuracy is worsened because the coefficients are determined from an (n+1) measurement point.  The calibration curve becomes a curve passing measurement points if the measurement points include a large measurement error for one point. Moreover, what degree is preferred cannot be detected beforehand and the coefficients are determined through comparison and calculation, which is a demerit to make the work complicate and difficult.

Title: Rotary encoder
Inventor: NISHIMURA TETSUJI
IPC: G01D5/38
Filed: 1988-09-22
Abstract: PURPOSE:To miniaturize the size and to reduce the thickness of a rotary encoder by utilizing diffracted rays of light of a specific number of order from a cylindrical diffraction grating coupled with a rotating object to be detected. CONSTITUTION:Luminous fluxes emitted from both end faces of a laser 1 are respectively changed to parallel rays of light 81 and 82 by means of collimator lenses 21 and 22. One luminous flux 81 is changed to clockwise circularly polarized rays of light and made incident on one point M1 of a diffraction grating 4. The other luminous flux 82 is changed to counterclockwise circularly polarized rays of light and made incident on another point M2 of the grating 4. Then the positive and negative m-th order diffracted rays of light of the diffracted rays of light respectively produced at the points M1 and M2 are superimposed upon each other through a non-polarization beam splitter 5. Since the superimposed diffracted rays of light become linearly polarized rays of light with the polarizing direction rotated following the rotation of the grating 4, bright-and-dark changes are produced by polarizing plates 61 and 62. When the grating 4 is turned by one grating pitch, the + or -m-th order diffracted rays of light change in phase by + or -2mpi and the rays of light passed through the plates 61 and 62 produce bright-and-dark changes 2m times and, as a result, 2m pieces of sine signals can be obtained from photodetectors 71 and 72.

Abstract: PURPOSE:To sew beautiful embroidery patterns and to prevent cloth from creasing by providing a sewing means whereby on the basis of both the output from an operation means and the output from a detecting means, a unit pattern for control is sewed with the amount of a feed pitch for the control. CONSTITUTION:In an operation circuit 10, a feed pitch for control is operated by both the output from a feed pitch-detecting circuit 15 and the designated value from a switch 1, and it is stored in a feed pitch-designating circuit 16. A decision circuit 18 for the number of patterns decides a sewing start point of a scallop pattern B1 for the control from the comparison between the number of the input from a sensor 17 and an initial preset value. When its circuit detects the sewing start point of the scallop pattern B1 for the control, it sends a read signal of the feed pitch for the control, to the feed pitch-designating circuit 16. According to the feed pitch for the control, which is read-out, a driving circuit 13 drives a pulse motor 12 and a sewing machine mechanism 11 sets a feed pitch for the feed pitch for the control, and thus the scallop pattern B1 for the control is sewed at the feed pitch for the control. A scallop pattern B2 following the B1 is also sewed at the same feed pitch as the scallop pattern B1.

Consequently, when both addresses coincide with each other, a selection signal SR is outputted and applied to word drivers 3 and 8. The word driver 3 when applied with the selection signal is inhibited to intercept the word line selection signal of a memory cell array 1, and the redundancy word driver 8 inputs a word line selection signal to a redundancy memory cell array 7 by being applied with the selection signal SR. Consequently, the redundancy memory cell array 7 is selected to write and read data in and out of the memory cell array 7.
