Title: Displacement measuring apparatus
IPC: G01B11/00
Filed: 1992-03-25
Abstract: PURPOSE:To make it possible to measure the relative three-dimensional displacement in high resolution without a powerfull light source by projecting a plurality of light beams on the light receiving surface of a two-dimensional incident-light-position detecting element, and operating the amount of the displacement at each incident spot position, respectively. CONSTITUTION:The luminous fluxes emitted from light sources 3 and 5, which are provided on a reference supporting stage 1, are condensed on the light receiving surface of a two-dimensional semiconductor position detector (two-dimensional PSD), which is provided on a material to be measured 2 through light projecting lenses 4 and 5 provided at a specified interval B. At this time, the light sources 3 and 5 are alternately lit and driven in time division. Thus, the approximately entire emitted luminous fluxes are condensed on the light receiving surface of the two-dimensional PSD. When the directions, which are in parallel with two longitudinal and lateral sides of the material to be measured 2 are made to be the (x) axis and (z) axis, and the direction orthogonal to two sides is made to be the (y) axis, the amounts of displacements DELTAx, DELTAy and DELTAz of the axes (x), (y) and (z) of the material to be measured have the relationships with the amounts of diaplacements of the spot lights C1, C2 and C3 as DELTAx=-C1, DELTAy=-C2 and DELTAz=C3L/B. L is the interval between the lenses 4 and 6 and the two-dimensional PSD. The amount of displacement of each spot light is obtained, and the three-dimensional displacement of the material to be measured 2 can be measured in high resolution without a powerful light source.

IPC: F23Q7/00
Filed: 1979-06-01
Abstract: PURPOSE:To take cigarettes out of a case one after the other, light the cigarette by automatically bringing a heater into contact with a tip of the cigarette, and let the filter tip project over the case, by the operation of a switch button. CONSTITUTION:A lid 34 is opened by a cam 11 with the rotation of a cam shaft 10 so as to let a piece of cigarette fall on a saucer 36. Next, the fallen cigarette 30 is picked up by a clip 18 operated by the second cam 12. Then a lever 24 is moved to the left in order to let the tip of the cigarette 30 come in contact with the heater 29 for lighting the cigarette, and it is moved to the right by the returning stroke of the lever 24 so that the filter tip of the cigarette 30 is projected over a case 1 through a taking out hole 43 of the case 1. At this time, although a rocking part 13 is also returned to a horizontal position, the clip 18 is disengaged from the cigarette because the tip of the cigarette 30 is held down by the taking out hole 43.

Title: Manufacture of aluminum foil for electrolytic capacitor
Inventor: ENDO EIJI
IPC: H01G9/04
Filed: 1990-03-20
Abstract: PURPOSE:To obtain aluminum foils for an electrolytic capacitor having large electrostatic capacity by dipping a foil in electrolyte or water applied by an ultrasonic wave in an intermediate step of etching and etching steps to clean it. CONSTITUTION:In manufacture of an aluminum foil for an electrolytic capacitor to be effectively etched, it is dipped in electrolyte or water applied by an ultrasonic wave in an intermediate step of etching and etching steps. The wave to be applied suitably has a frequency of 10-100kHz even if the foil is for low to high voltages. Applying time is about 5 seconds to 5min, substantially equal to cleaning time. The cleaning liquid to be applied is normally water, but may be electrolyte. Its temperature is generally suitably 10-60 deg.C. Accordingly, since aluminum ions or aluminum fine powder generated in a pit during electrolytic etching can be effectively removed in the electrolyte or water by an ultrasonic vibration, etching conditions of rear stage become constant, and the etching is uniformly proceeded.

IPC: G11B5/54
Filed: 1979-06-01
Abstract: PURPOSE: To make soft floating possible by fixing electromagnets to a load arm and carriage assembly and then by generating repulsive force by exciting coils of both electromagnets at an adequate point in time.  
     CONSTITUTION: The floppy-disk drive mechanism is so constituted that the moment head 7 comes into contact with disk 4, the downward motion force of load arm 2 is releaved by repulsive force between magnets 21 and 22. Namely, when head load actuator 1 is released, load arm 2 starts lowering by the force of spring 6 to bring surface head 7 into contact with the disk surface. For the purpose, damping by magnets 21 and 22 is started right before the head meets the disk surface, so that head 7 will softly be loaded on disk 4 without jumping.

Title: Satellite tracking system
Inventor: TSUJINO MITSUHISA
IPC: G01S3/42
Filed: 1995-03-28
Abstract: PURPOSE: To predictively track a satellite even when the past locus information of the satellite is not available by conversely preparing the past locus information of the satellite by using locus element parameters. CONSTITUTION: The presence/absence of a sufficient quantity of past locus information of a satellite is discriminated and, when a sufficient quantity of information is available, the past locus information during a fixed period is read out from a storing section and the locus function of the satellite is calculated by using a mathematical method, such as the method of least squares. Then, when it is discriminated that positional information storing time has come, the position of the satellite at present time is calculated by using the locus function of the satellite and an antenna is driven. When it is discriminated that no sufficient quantity of information is available, the presence/absence of eleven locus elements is discriminated and, when the elements exist, the past locus information of the satellite is prepared from the eleven elements and recorded.  When the eleven elements do not exist, the locus information of the satellite is accumulated by performing satellite tracking operations, such as the step tracking, etc., until the predictive tracking of the satellite becomes possible as in the past.
