Title: Length measuring device used at extremely low temperature
Inventor: KURAOKA YASUO
IPC: G01B21/00
Filed: 1979-04-09
Abstract: PURPOSE: To measure the length of an object at a high accuracy even at an extremely low temperature by using a measuring rod and a reference rod wherein the expansion and contraction of the rods with respect to variations in temperature are offset, whereby the length of the object can be measured accurately irrespective of the lengths of the rods.  
     CONSTITUTION: A measuring rod 3 and a reference rod 4 of the same material are set in a coolant 2 placed in a thermostatic vessel 1 of an extremely low temperature, such that both of the rods 3, 4 are extended out of the vessel 1. The measuring rod 3 consists of a fixed portion 3' disposed at a lower portion of the interior of the vessel 1, and a movable portion 3" which can be vertically slided to set an object M to be measured, in the coolant 2 and between the movable portion 3" itself and the fixed portion 3'. An amount (q) of displacement of the movable portion 3" with respect to the reference rod 4 is measured outside the vessel 1. Thus, the length of the object M can be accurately measured.

Title: Stabilizing method for secular characteristic in electrochemical material detection
Inventor: FUJIOKA TORU
IPC: G01N27/416
Filed: 1988-02-24
Abstract: PURPOSE:To refresh a working electrode and to perform electrochemical reaction smoothly at all times by varying the working electrode potential temporarily. CONSTITUTION:The potential of the working electrode 3 is varied temporarily. Consequently, the working electrode 3 which is cleaned is refreshed. Consequently, the electrochemical reaction is carried out continuously and smoothly and variation of a measurement current with time is precluded, so secular characteristics of detection are stabilized. The electrode is cleaned because the electrochemical reaction is not performed smoothly owing to the adsorption, etc., of a nonreaction material or reaction product on the surface of the electrode when the working electrode 3 is operated in a constant-potential state. Therefore, temporary variation in the potential of the working electrode 3 precludes an increase in the amount of an impeding material on the surface of the electrode owing to the cleaning effect, etc., and also prevents a change in the physical chemical state of the surface.

Title: Photographic lens having short overall length
Inventor: TAKADA KATSUHIRO
IPC: G02B9/00
Filed: 1986-02-28
Abstract: PURPOSE:To constitute a lens which has satisfactorily compensated aberations of various kinds and has about 1.0 telephoto ratio and a very short overall length, by including a lens system with refractive index variably distributed in the direction of the optical axis in constituting elements of a front group having the converging function and a rear group having diverging function. CONSTITUTION:This lens system consists of four lens groups, namely, a positive meniscus lens whose convex is directed to the object side, a double concave lens, a lens having a positive refracting power, and a negative meniscus lens, and the converging system of the front group consists of the first - third lens groups, and the converging system of the rear group consists of the fourth lens group. The refracting power of lenses in the front group is weakened to suppress higher aberrations and the assembling error is reduced, and a distributed index lens is used as the fourth lens to enhance its diverging function. The out-axis beams are diverged by the last lens having a wide field angle to compensate the coma, and the negative astigmatism generated in the first - third lens groups is compensated with respect to the out-axis beams; thus obtaining the photographic lens having about 1.0 telephoto ratio and a very short overall length.

Title: Measuring method of signal detection time
Inventor: KOMADA KENICHI
IPC: G04F10/00
Filed: 1978-04-11
Abstract: PURPOSE: To secure an accurate and highly efficient detection measurement of the signals by detecting and memorizing both the rise and fall of each detection pulse of the sensor in the measurement of the signal propagation speed in the metal and thus obtaining the stop signal of the counter.  
     CONSTITUTION: The sound wave is excited in alloy wire 2 by the control of minicomputer 5, and at the same time the clock given from generator 6 is supplied to counter 17 and 18. The propagation signal in wire 2 is detected by sensor 3 and 4 to be applied to input terminal 10 of the signal isolator circuit. The rise of the detection pulse given from sensor 3 is isolated 11 to stop counter 17 and also memorized 12. And when the output level is in agreement with the level of the fall time when given inverse detection 13, the signal level is memorized 14. On the other hand, the rise of the detection pulse is detected 15 for sensor 4, and the pulse delivered by the signal of circuit 14 stops counter 18. Computer 5 thus calculates the propagation speed of the signal based on the contents difference between counter 17 and 18, the clock pulse duration and the distance between sensor 3 and 4 each.

Abstract: PURPOSE:To correct the output level to a prescribed level in the case that the output level is much changed and normal correction is impossible by preliminarily holding change data, which changes control data which keeps the normal output level of a base band part, in a ROM newly provided in a control part. CONSTITUTION:If a comparison circuit 1111 of an automatic correction circuit 111 detects the excess of a control voltage Vcont of a variable attenuator 1 over a prescribed threshold 1112 to output a detection signal c and it is judged by this signal C that normal automatic control of the transmission output level in the variable attenuator 1 is impossible, a set change signal generating circuit 1113 of the automatic correction circuit 111 generates a set change signal (d) and reports it to a control circuit 102 of a control part 10. The control circuit 102 reads out preliminarily set change data from a ROM 101 and sends set change data to a base band part (a) to raise or reduce the output level of the base band part (a) Thus, the transmission output level of the output of a radio transmission part (f) is controlled to a prescribed value.

Title: Electro-optical lens-barrel
Inventor: NAKASUJI MAMORU
IPC: H01L21/30
Filed: 1985-03-07
Abstract: PURPOSE:To obtain an electro-optical lens-barrel which can adjust the beam without fusing beam forming aperture by first changing intensity of condenser lens in the side of weakening excitation and thereafter changing intensity of condenser lens in the side of enhancing excitation. CONSTITUTION:A crossover image 3 must be aligned with the center of deflection of deflection electrode 13 which changes a beam size. A beam current density can be changed by adjusting two condenser lenses 6, 7 and changing only the crossover magnification factor, without changing a crossover image position 3. The beam current density can be increased by enlarging a crossover image 3. For this purpose, it is necessary to weaken the excitation of condenser lens 6 and move the crossover image 2 in such a direction as becoming far from an electron gun 30. In this case, the crossover image 3 moves in the direction as becoming far from a molding aperture 11, a crossover image 4 also moves in the direction as becoming far from a molding aperture 12 and the perture is not fused. Excitation of condenser lens 7 is enhanced and thereby a crossover images 3-5 are returned to the normal positions.

IPC: B43L11/04
Filed: 1990-02-22
Abstract: PURPOSE:To mechanically draw an ellipse by providing a constitution in which the supporting point of a bar passes through a cross road and an attachment aperture is open in the bar. CONSTITUTION:The distance between A and B and the distance between B and C as shown by figure 1 are replaced by the distance between A' and B' (L, A') and the distance between B' and C' (I, C') as shown by figure 2. Then if an attachement aperture (C') is rotated clockwise with the supporting point (B') of figure 2 as its center, a supporting point (A') moves upward and a supporting point (B') moves to the right. Subsequently, the orbit of an attachment aperture (C') become elliptic. Further, if the distance between the supporting points B' and C' (I, C') of a bar (C) is increased, the elliptic orbit becomes a circle, and if the distance is decreased, the elliptic orbit becomes close to a line. Consequently, a compass which draws an ellipse mechanically is obtained.

Title: Solid electrolytic capacitor
Inventor: MORIMOTO TAKESHI
IPC: H01G9/012
Filed: 1990-02-27
Abstract: PURPOSE:To obtain a solid electrolytic capacitor having small leakage current and stable performance by disposing the mounting position of a negative lead terminal on a conductor layer disposed substantially perpendicularly to the bonded part of an anode foil to a positive lead terminal. CONSTITUTION:The mounting position of a negative lead terminal is disposed on a conductor layer disposed substantially perpendicularly to the bonded part an anode foil to a positive lead terminal. That is, since the anode foil used for an aluminum electrolytic capacitor is generally thin of several tens of microns, the foil is flexible. When it is used in combination with solid electrolyte, a leakage current is increased even by a small impact during manufacturing. Accordingly, the mounting position of the lead terminal is specified at a position which is stronger than the other part to remove its disadvantage, thereby reducing the leakage current. Thus, a solid electrolytic capacitor having small leakage current by the use of the conductive polymer compound as solid electrolyte and stable performance can be obtained.
