Abstract: PURPOSE:To facilitate the correction of the electron beam locus, by providing a pair of projected bead glass chips for holding the mutual interval of each electrode to surround the electron beam locus while magnetizing by the projected chip. CONSTITUTION:The electron gun 3 is comprised of a cathode 10, G1 electrode 11, G2 electrode 12, G3 electrode 13, G4 electrode 14 and a pair of bead glasses 15, 15 facing each other, where the cathode 10 and the electrodes 11-14 are planted in the glasses 15, 15 to hold the mutual interval. The glass 15 has the magnetizable performance while provided with a plurality of integrally projected chips 15a which are provided between the electrodes 13, 14 to surround the locus of the electron beams 4B, 4G, 4R.

Title: Solid electrolytic capacitor
Inventor: NIWA SHINICHI
IPC: H01G9/028
Filed: 1993-03-11
Abstract: PURPOSE:To provide a solid electrolytic capacitor which excels in the characteristics of high frequency and leakage current in which short-circuiting defects can be prevented from being brought about at a constanttemperature loading test by improving the electrolyte of a solid electrolytic capacitor. CONSTITUTION:A TCNQ complex salt of 3,5-lutidine of two molecules coupled by substituting 1,8-n-octyl for N-position is melted by heating and used as the electrolyte of a capacitor element for impregnation and then is cooled for solidification. Thereby, since the melting points of OS-BQ and OS-OL respectively are 210 to 215 deg.C and 225 to 230 deg.C, the OS-BQ is changed to the OS-OL, thereby increasing the melting point to stabilize the leakage current characteristic and improving the breakdown strength. Therefore, it can have the rated voltage of higher than 25 volts. The electric conductivity of the OS-OL after melted and solidified is inferior as compared with the OS-BQ, but the high-frequency characteristic which is the feature of a TCNQ type capacitor is not remarkably damaged.

Filed: 1998-03-03
Abstract: PROBLEM TO BE SOLVED: To purify the crude product of the subject compound into a high-purity product useful as a functional monomer or an intermediate for a medicine and an agrochemical in a high recovery ratio and simply, by bringing the crude product into contact with an acid catalyst so as to decompose impurities and to convert the crude product into the subject compound. SOLUTION: (A) A crude α-hydroxymethylacrylic acid ester (e.g. one obtained by reacting an acrylic acid ester with formalin in the presence of a basic catalyst) containing α-methoxymethoxyacrylic acid ester is brought into contact with an acid catalyst (e.g. a mineral acid, a solid acid, an organic acid or an acidic ion exchange resin). Preferably the purification is carried out by filling and fixing the acidic ion exchange resin to a column or the like, passing the component A into the column at 30-50 deg.C or bringing it into contact with the column by a circulation method. Consequently since the decomposition rate of impurities can be increased and the separation operation such as filtration or the like of the component B is not followed, the a hydroxymethylacrylic acid ester can be simply purified in high productivity.

Title: Memory
Inventor: KANEKO REIZO
IPC: G11B9/06
Filed: 1988-03-04
Abstract: PURPOSE:To stably contact and slide a head on the surface of a storage medium with a minute load and minute frictional force by detecting the frictional force when the head is contacted and slid, adjusting the pressing force of the head to the storage medium according to the detected frictional force, and controlling the frictional force within a constant range. CONSTITUTION:When a head 1 is contacted and traveled on a storage medium 3, a parallel spring 5 is bent by the frictional force generated by the contact and the slide of both of them. The displacement is detected by a displacement detecting mechanism 6 and adjusted by a frictional displacement control circuit 8 and a deflection adjusting electromagnet 7 so that the deflection can be zero all the time. A frictional force control circuit 9 makes the suction force of the electromagnet 7 into its input and controls the pressing force of the head 1 to the storage medium 3 so that constant frictional force can be generated all the time by decreasing the current of a load adjusting electromagnet 4 when the frictional force is excessive and increasing the current when the frictional force is too small. Thus, the head 1 can be stably contacted and slid on the surface of the storage medium 3 with the minute load and the minute frictional force.

Abstract: PURPOSE:To improve the activity of the subject magnetite by keeping a magnetite raw material at a specific temperature, applying high voltage to supply electron and expelling O2 molecule by the electron to effect the activation of magnetite. CONSTITUTION:A chamber 2 is evacuated by closing shut-off valves 5, 6 and is maintained at about 250-350 deg.C by heating the outer circumference of the chamber 2 with a heater 1.

Title: Device for checking circuit substrate
Inventor: OOAMI TAKESHI
IPC: G01R31/316
Filed: 1980-04-18
Abstract: PURPOSE:To judge the quality of the substrate to be checked, by selecting two arbitrary check points in a reference substrate and the substrate to be checked, connecting the chekpoints of the reference substrate and the substrate to be checked, applying voltages to the remaining checkpoints of both substrates, and measuring the potential at the connecting point. CONSTITUTION:In the case quality of a circuit between the first and second check terminals TP0 and TP1 of the substrate to be checked is judged, the terminal TP1 and a terminal TP0' of the reference circuit are connected, a voltage +V is applied to the terminal TP0, and another terminal TP1' is grounded. Then, a potential V0 at the connecting point becomes V/2 under normal conditions. If there are short circuts, pattern breakages, and the like, the potential V0 is deviated from V/2, and the quality of the circut can be identified. The judgement of the quality is performed in consideration of dispersion delta among elements. Switches S1-S6 are controlled by a microcomputer and the like. The switches S5 and S6 establish the dispersion delta. If the voltage exceeding a standard limit is imputted to a comparators 1 and 2, an output OUT-1 or OUT-2 varies accordingly, and abnormal state is identified.
