IPC: G01N1/28
Filed: 1997-02-20
Abstract: PROBLEM TO BE SOLVED: To provide an X-rays analyzing sample holder capable of accurately X-ray-analyzing by an upper face irradiation type fluorescent X-ray analyzer without pressurizing and molding a power sample. SOLUTION: An opening part 10 at one end of a cylindrical sample cup 3 of an X-rays analyzing sample holder 1 is clogged by a cover sheet 12 made of resin. This sample cup 3 is inserted into a sample holder 2. A porous material 14 is placed in the sample cup 3, and a power sample 13 is pinched between the resinous cover sheet 12 and the porous material 14. This porous material 14 is pushed against the sample 13 by an elastic force of an elastic holding member 4, whereby the sample 13 is abutted against the cover sheet 12 and also this cover sheet 12 presses one end part of the sample cup 3 mounted to a stopping part 8a of the sample holder 2.

Title: Thickness matering method using radioactive rays
Inventor: MASANOBU KAZUNORI
IPC: G01B15/02
Filed: 1978-03-30
Abstract: PURPOSE: To meter the thickness of an article at a high accuracy, while reducing the adjustment,  by interchanging resistors in accordance with the thickness of the article to compare a reference  value, which is given in advance with the use of a reference member, when it is intended to  change the metering range, so that the gain compensation is performed with the difference is  larger than the allowable range.   
     CONSTITUTION: A feedback resistor 36a to be used for metering a thin article is connected in  parallel with an operational amplifier 34 through a change-over device 35 and is adjusted such  that the output of the amplifier 34 becomes the maximum under the condition having no article  to be metered. A reference member 45 having a known thickness is interposed between a radioactive ray source 30 and a detector 32 so that the reference value is stored in a constant presetter 41. A resistor 36b takes the part of the resistor 36a, and the reference member 45 is also interposed between the source 30 and the detector 32 so that the thickness of the plate is detected by  means of an operational amplifier 38. The difference is deduced between the value thus obtained  and the value stored in the presetter 41, and the gain value is compensated, when the difference  is larger than the allowable range, and is stored in the amplifier 38. When the article 35 is carried between the source 30 and the detector 32, the resistors 36a and 36b are selectively connected  by the amplifier 38 in accordance with the thickness so that the resultant thickness is displayed  in a meter 44.

Title: Carrier recovery circuit
Inventor: SAITO MASAKATSU
IPC: H04L27/00
Filed: 1988-02-19
Abstract: PURPOSE:To attain carrier recovery with high accuracy by outputting the pulse signal of a prescribed duty ratio to a loop filter as a control signal when it is detected that a demodulating signal is near a prescribed signal point with using an identified result. CONSTITUTION:The control signal to be prepared by a logic circuit 31 is supplied to a control circuit 32. At such a time, when the demodulating signal is not near the prescribed signal point, this control signal is supplied through a loop filter 33 to a voltage controlled oscillator 34 as it is. On the other hand, when it is detected by the control circuit 32 that the demodulating signal is near the prescribed signal point, the control signal 32 supplies the pulse signal of the prescribed duty ratio (50% preferably) to the loop filter 33 as the control signal. This operation corresponds to fix an oscillating output when the signal is pulled in near the signal point. Thus, since the oscillating output is fixed near the signal point, an unnecessary spectrum can be suppressed to be generated since the signal values of '1' and '0' are repeated for a comparatively long period.

Title: Offset and sensitivity correcting circuit for p-n junction type infrared ray multielement detector
Inventor: MATSUURA YOSHIO
IPC: H04N5/378
Filed: 1989-02-15
Abstract: PURPOSE:To make a circuit scale small by executing an offset correction by means of the subtraction of a line mean level. CONSTITUTION:An IRCCD (infrared ray detector) output to be outputted in serial is A/D-converted and, thereafter, stored in a frame memory 6 once in a wide dynamic range. The stored image data are read as the image data for one horizontal line, and the mean value for one line is calculated by a line mean calculating circuit 10. On the other hand, the mean value calculated by the circuit 10 is subtracted from the image data for one line by means of a subtracter 11. In such a stage, since the mean value of each horizontal line is clamped at zero, a pattern noise in a line shape can be removed. Next, the sensitivity dispersion of each element is corrected by a sensitivity correcting circuit 5. In such a system, since the necessity to acquire correction data for the offset correction is eliminated, an optical mechanism to acquire them is made necessary. The circuit scale is made small.

Filed: 1998-02-19
Abstract: PROBLEM TO BE SOLVED: To accelerate a garbage collection processing which releases a memory area that becomes unnecessary and to enhance the processing efficiency, in a processing which dynamically allocates memorys. SOLUTION: A memory allocation history after a certain point of time is held in a history buffer BF and also a heap mark is attached to a memory cell, which a pointer indicates when the pointer is changed. And a memory is released in the following way. A route pointer RP is scanned and a route mark '#' is attached to all memory cells that are indicated by the pointer RP. The buffer BF is scanned and all of the route marks and heap marks that are indicated by the buffer BF are checked. When neither route marks nor heap marks exist, the memory cell is released. The history buffer is made empty. By this method, it is possible to simply and quickly release a memory area that is no more needed. Furthermore, a reference count system can be used instead of attaching a heap mark.
