Title: Digital filter
Inventor: TANAKA YOSHIAKI
IPC: H03H17/06
Filed: 1985-09-27
Abstract: PURPOSE:To reduce ripples at a flat region by switching polarity of the coefficient of a digital main filter inversely or non-inversely to changeover the main filter to an HPF or LPF. CONSTITUTION:One-sample delay sections 161-16l, multiplication sections 141-14l, and adder sections 131-13l constitute an HPF or an LPF. One-sample delay sections 121-12m and a multiplication section 3 constitute a full band filter 2. Coefficients a1-al fed from the multiplication sections 141-14l are fed to a terminal 9 of a code inverter 10, and the polarity of the coefficients a1-al is switched by a switching signal d2. The coefficients a1-al are set to function windows. In obtaining a high frequency emphasis characteristic, the inverter 10 makes the filter coefficients, except the coefficient am, negative to constitute a high frequency filter 11a and a switch 5 sets a coefficient at1.

Title: Detection method of chemical composition and property derived from it by means of near infrared rays
Inventor: TAMURA KOICHI
IPC: G01N21/35
Filed: 1994-09-08
Abstract: PURPOSE: To provide a detection method in which a detection can be performed with high accuracy by a method wherein, when the chemical composition of a certain substance is detected by irradiation with near infrared rays, a closely related wavelength region is detected and a working expression is created. CONSTITUTION: Many samples whose chemical composition values are known are irradiated with near infrared rays at required wavelength intervals within a wavelength region which issues promissing information, and their absorbance is received. Regarding various received wavelengths, the sum of squares of a deviation and a correlation coefficient are found in the relationship between the chemical composition values of the samples and their absorbance. Whenever the absolute value of a loading weight value (an Lw value) as the function of a product of both becomes minimal, it is sorted, and a regression line is found on the basis of the chemical composition values of the respective samples and the absorbance of the respective wavelengths in a wavelength section including a maximal Lw value.  It is expressed in a numerical formula, and a working expression is obtained while the absorbance with reference to the respective wavelengths is used as a variable and the detection value of a chemical composition is used as a function. An object whose chemical composition value is unknown is irradiated with the near infrared rays at the respective wavelengths in their wavelength section, its absorbance is applied to the working expression, and its chemical composition value is detected.

Abstract: PURPOSE:To enable the formation of a focused image in any position of an original at free magnification rates and to make possible the superposed projection of the original by providing a spot light source, means for controlling the distribution of the reflected luminous flux and means for shaping the luminous flux which determines the direction of the reflected luminous flux so as to focus the reflected luminous flux approximately at the specified point. CONSTITUTION:The 1st reflection mirror M1 constitutes the control means for the luminous flux reflected therefrom. The reflected luminous flux is the uniformly distributed luminous flux and the distribution thereof can be changed as desired by designing the shape of the reflection mirror M1. On the other hand, the 2nd reflection mirror M2 is so designed that the luminous flux reflected thereby focuses at one point 13 on the axial line O-O. Said mirror constitutes the means for shaping the luminous flux. The luminous flux reflected from the 2nd reflection mirror M2 is the uniformly distributed luminous flux which is emitted from one point 13 and has specified directivity. If the original 11 is placed in the mid-way of such luminous flux, the focused image is formed on a screen S at any distance at which the original 11 exists with respect to the focusing point 13.

Filed: 1999-07-29
Abstract: PROBLEM TO BE SOLVED: To reduce the current consumption of an input output circuit for a semiconductor device. SOLUTION: An input output circuit 11 has a control signal generator 116 that controls a selective operation of a selector 113 and an output operation of a tristate output buffer 115 with two different control signals OE, SEL respectively. In an input state, where the tristate output buffer 115 reaches the high impedance state by one (OE) of the different control signals, when the selector 113 selects consecutive data streams D1-D4 given to an input output common use terminal 10a of an input buffer 111 and the output buffer 115 as external input data and an output side latch 114 latches the data stream, a selector control signal SEL of the selector 113 is generated in only the same clock timing as a data output timing of the final order, in consecutive data streams to allow the output side latch 114 to latch only the final data D4.  Thus, number of times of operations of the output side latch at an input operation can be suppressed, to reduce the current consumption.

IPC: G11B33/10
Filed: 1984-10-15
Abstract: PURPOSE:To prevent completely the attachment of the wear powder to a magnetic head by defining the minimum distance C between the center of the head in its thickness direction and the edge of a window for attachment of the head in its height direction and dividing the C by a half H of the thickness of the magnetic head to obtain epsilon to satisfy epsilon>=10. CONSTITUTION:The dimensional form of a magnetic head attachment window 7 is limited to secure an ideal contact between a magnetic head 5 and a magnetic tape 1. Thus an element is detected from the dimension itself of the window 7 to improve greatly the characteristics of the head 5. In case the actions of the tape 1 are logically analyzed at a place near the head 5, a partial differential equation showing a tape deformation is defined as shown here when the tape deformation amount is referred to as w (x, y) is the normal line direction of the tape surface. In this case, (h), E, mu, (r), TO, F and delta mean the thickness of the tape 1, a Young's modulus, a Poisson ratio, the radius of a rotary member, the tape tension, the concentrated power affecting the tape and a Dirac's delta-function, respectively. Then the answer of said differential equation is obtained as a Green function. Thus the tape deformation is simulated.

Filed: 1987-08-28
Abstract: PURPOSE:To speed up spectral analysis by moving a slit which extends in a spectrum spread direction in front of a spectrum image as a shutter for exposure at a monotonously varying speed at right angles to the wavelength spread direction. CONSTITUTION:The shutter S is lifted before exposure to cover the front surface of a film.

Filed: 1996-07-29
Abstract: PROBLEM TO BE SOLVED: To effectively avert the occurrence of unequal luminance and to surely prevent a light guiding plate moving to the light source side by forming a stopper on the exit surface side on the front is side facing the end face of a plate member and positioning the plate member so as not to move to the primary light source side. SOLUTION: The light scattering light-guiding plate 12 which receives the illumination light emitted from a fluorescent lamp 6 from an incident surface T and emits the light from an exit surface, has the stopper 12A which projects from the incident surface side at a wedge-shaped front end and meshes with a recessed part formed on the inner side of a frame 11, thereby, the displacement to the fluorescent lamp 6 side is effectively averted. The occurrence of the unequal luminance is effectively averaged by forming the stopper 12A of this time at the edge-shaped front end. The sufficient area and strength are assured at the wedge-shaped front end, by which the failure of the fluorescent lamp 6 is effectively averaged. Since the front end is formed think, the accurate production of the light scattering light-guiding plate 12 is made possible.
