Title: Preparative chromatography and device thereof
Inventor: EIKI YOSHIHIRO
IPC: G01N30/80
Filed: 1989-03-27
Abstract: PURPOSE:To exactly decide a peak refining degree by subjecting a sample to liquid chromatography and passing an eluate through a photodiode array detector. CONSTITUTION:The preparative liquid chromatography device 1 is set under the same chromatograph conditions as the conditions at the time of fraction collection and the standard sample of the component desired to be fraction- collected is injected into a sample injecting part 4 in the case of executing the recycling fraction collection of X times with the preparative liquid chromatograph device 1. The holding time A and spectra of the standard sample are stored. The operating conditions of a photodiode array detector 6 are set in accordance with the holding time after the recycle X times calculated from the time A and the time when the sample is transferred in a recycle flow passage (b). A sample is injected after the setting and the recycle dispersion is started. A flow passage selector valve 7 is set in the recycle position at the prescribed time and the taking of monitor data is started by the photodiode array detector 6. The peak including the desired component is checked by a detection parameter and the peak rise, vertex and falling time are measured. The peak refining degree is exactly decided in this way.

Filed: 1992-02-28
Abstract: PURPOSE:To provide a method for correctly and quickly analyzing the composition of components before and after a reaction accompanying the change of isotopic ratio of <13>C, and isotopic ratio of <13>C, CONSTITUTION:According to the gas chromatography/mass spectrometry, a specific molecule and a specific fragment ion of each of the total components to be measured are selected. The strength of all the isotopic ions related to <12>C and <13>C of the selected ion is measured. The amount of components is obtained from the sum of the ionic strength, and the ratio of isotopes of <13>C is calculated from the ratio of the ionic strength of isotopes. This method thus analyzes a product. Accordingly, both the minute generating amount of a product and the ratio of isotopes of <13>C resulting from a laser reaction can be concurrently and accurately measured, and also the material balance related to <13>C in the reaction system can be calculated.

Title: Field effect transistor
Inventor: SHIOZAKI OSAMU
IPC: H01L21/338
Filed: 1988-03-31
Abstract: PURPOSE:To reduce the capacitance between gate and source, and the capacitance between gate and drain, without fining gate length, and enable the title transistor to be applied in a high frequency region, by forming a low carrier concentration region with a shallow depth from a surface, in a region of an active layer just under the gate, and in the vicinity thereof. CONSTITUTION:In an active layer 2 just under a gate, a low concentration region 5, where carrier concentration of the active layer 2 is decreased, is formed. The depth of the low concentration region 5 is desirable to be nearly equal to the thickness of a surface depletion layer at the time of gate zero bias. Since the low concentration region 5 of carrier is formed only in the active layer 2 just under the gate electrode 6, and in its vicinity, capacitance between gate and source, and capacitance between gate and drain can be reduced without fining the gate length. Further, since the depth of the low concentration region 5 is made equal to the depth of the depletion layer at the time of gate zero bias, the region is made as a complete depleted state at an operating point when the gate bias is applied, so that mutual conductance is never sacrificed.

Abstract: PROBLEM TO BE SOLVED: To provide a game machine in which the rate of ball discharge per unit time can be easily estimated and the discharge of balls in a Pachinko game hall (for Japanese pinball game) can be controlled with ease. SOLUTION: In a Pachinko machine 1, when Pachinko balls enter an ordinary variation character 4, the change of three picture patterns displayed on a picture pattern display part 3 starts.

When a 'li-zhi (reach) picture pattern' is displayed, the picture pattern changes in accordance with a change pattern with a long base change time irrespective of a game state. When the 'reach picture pattern' is not displayed, the picture pattern under a 'high probability state' changes in accordance with the change pattern of a long base change time more probably than that under a 'low probability state'.

Title: Magnetic head
Inventor: SENDA MASAKATSU
IPC: G11B5/33
Filed: 1994-03-22
Abstract: PURPOSE:To enhance reproduced output, SN and sensitivity by providing a part of magnetic materials with a gap. CONSTITUTION:This magnetic head is provided with two pairs of electrodes 1a, 1a', 1b, 1b' from both ends of a detecting conductor 2, is provided with the magnetic materials 3a, 3b so as to turn around the detecting conductor 2 and is provided with a nonmagnetic insulator 4 and the gap 5. The gap 5 is formed of the detecting conductor 2b. Signal currents are passed to the detecting conductor 2 to magnetize the magnetic materials 3 and a magnetic medium is magnetized for recording by the magnetic fields leaking from the gap 5 at the time of executing recording. The change in the magnetic fields of the medium is converted to an impedance change by the change in the specific magnetic permeability of the magnetic materials 3 and this impedance change is converted to voltage by a four terminal method, by which reproducing is executed. The high-frequency magnetic fields are reflected and absorbed by the magnetic materials 3. The thickness of the magnetic materials is thereby made settable at a large thickness and the high dependency of the impedance of high frequencies on the external magnetic fields is more effectively utilized. The leakage of magnetic fluxes is lessened and the higher reproduced output, SN and sensitivity than those of the conventional magnetic heads are obtd.

Title: Recording system for gradation image
Inventor: KUBOTA KAZUNARI
IPC: G06K15/10
Filed: 1980-06-06
Abstract: PURPOSE:To accomplish a simple and stable thermal recording of gradatin images by a method wherein the area of printing by color development is changed by making a plurality of heating element correspond to each picture element of an original picture, and the combination of the heating elements which are energized with current is changed for the same density. CONSTITUTION:The gradation information fed from a line buffer 6 and corresponding to the picture elemnt is converted into driving signals for a printing unit 3 by a signal converting circuit 4. In this case, the printing area within each picture element is changed according to the gradation of the picture element, whereby a gradation recording is accomplished. In addition, by selecting at random or cyclically the heating elements 1' in the unit 3 which are driven, it is possible to prevent the generation of grain direction streaks. Furthermore, when the heating elements of different sizes are provided in one printing unit and the number of the heating elements energized with current is controlled in the combination with the printing areas of different sizes, the fidelity of the reproduction can be further enhanced. Accordingly, it is possible to obtain a high-quality gradation image which is stable against the changes in color-developing characteristics of the heat-sensitive paper and changes in environmental conditions.
