Title: Column filler for high precision liquid chromatography for analyzing amino acid
Inventor: ONO TAKAE
IPC: B01J20/286
Filed: 1992-06-30
Abstract: PURPOSE:To obtain an inexpensive and chemically stable column filler by treating alkyl group-coupl silica gel in an aqueous solution of alkylsulfuric acid alkali metal salt and copper sulfate. CONSTITUTION:The title column filler is obtained by subjecting modified silica gel to solid-liquid separation and washing with water after making an arbitrary alkyl group-coupl silica gel sold on the market as a filler for high precision liquid chromatography (LPLC) to react in an aqueous solution of alkylsulfuric acid alkali metal salt expressed by R1SO2Na (where, R1 represents the alkyl group), such as sodium or potassium salt and copper sulfate. When a column packed with this filler is used, amino acid which is high in polarity and low in UV absorption sensitivity can be directly separated in a stable acidic aqueous solution by prolonging the retention time without changing in advance the amino acid to a derivative of phenyl isothiocyanate, etc. Therefore, highly accurate analysis can be carried out.

Title: Gyrotron oscillating tube
Inventor: HAYASHI KENICHI
IPC: H01J25/00
Filed: 1986-07-24
Abstract: PURPOSE:To prevent positive ions generated in a collector from flowing in a MIG and an output window so that long-pulse and continuous operations can be performed, by interposing insulated metallic cylindrical electrodes between a high-frequency circuit and the collector, and between the collector and the output window part, respectively, and then by impressing the voltage, which is about 500V low against the collector, on the metallic cylindrical electrodes. CONSTITUTION:Metallic cylindrical electrodes 16 insulated by using insulating ceramics 12 and 14 are interposed between a high-frequency circuit 2 and a collector 5. And, metallic cylindrical electrodes 17 insulated by using insulating ceramics 13 and 15 are interposed between the collector 5 and the output window part 6. Voltage which is about 500V low against the collector is impressed on these metallic cylindrical electrodes 16 and 17 by using a d-c source 18. Because positive ions generated in the collector 5 are captured by the metallic cylindrical electrodes 16 and 17 biased in potential lower than the collector in such a gyrotron oscillating tube, the positive ions do not flow in a MIG 1 and the output window part 6, and therefore the MIG 1 and the output window 5 can be prevented from being damaged, and resultantly long-pulse and continuous operations can be performed.

Abstract: PURPOSE:To simplify the operation of a tape recorder, by reversing the direction of a tape on the basis of the center position of an operating element and then starting  the tape recorder when the operating element of a driving device which increases the  tape travelling speed in response to the degree of operation from the center position  exceeds the center position. CONSTITUTION:The voltage +B is applied to the middle point of a variable resistance  VR1, and both ends of the VR1 are grounded. An operating element is connected to the  base of a TR via a resistance R1. Thus the emitter current is controlled and fed 3a to  a driving controller 3. A variable resistor VR2 coupling to the VR1 is connected between the voltage +B and an earth, and the middle point of the VR2 is fed to the plus  terminal of a comparator 4 in the form of the reference voltage. Then the operating  element is connected to a terminal of the comparator 4, and a signal 1 or 0 is delivered in accordance with the position of the operating element to control 3b the driving. At the same time, the change of the signal 1 or 0 is differentiated 5 to perform  the driving control 3c. As a result, the pulses are fed 3c when the operating element  exceeds the center position, and the turning direction is decided by the signal 3b. The signal 3a controls the speed. Thus a desired recording position of audio signals can be  obtained with just a single operation. This operation is suited to the editing work.
