Title: Nut for feed screw and feeding device
Inventor: KATAYAMA ICHIRO
IPC: F16H25/20
Filed: 1993-06-16
Abstract: PURPOSE:To improve the feeding accuracy of a nut by providing a pair of guide pins set on both sides in the radial direction of a screw shaft, and abutted in the spiral groove of the screw shaft. CONSTITUTION:Since a pair of guide pins 46 and 48 are abutted in a spiral groove 14 on both sides in the radial direction of a screw shaft 12 in this nut 44 for feed screw, the pair of guide pins 46 and 48 absorb the variation amount when the rotating center of the rolling effective diameter of the screw shaft 12 is varied by a run-out. That is, when the screw shaft 12 is observed from the side, the incline of the spiral groove 14 is reversed at the near side and at the opposite side of the screw shaft 12. As a result, when the rolling effective diameter of the screw shaft 12 is varied, one side guide pin 46 receives a force pressed to the front end side, while the other side guide pin 48 receives a force pressed to the base end side. Consequently, the forces received by both guide pins are set off, the variation can be absorbed, the movement of the nut in the axial direction of the screw shaft 12 by the variation of the rolling effective diameter can be prevented, and the feeding accuracy of the nut is improved.

Abstract: PROBLEM TO BE SOLVED: To avoid the excessive scanning or scanning shortage of a video signal on a raster, to prevent the loss of picture information, and to sufficiently use a display screen by selecting horizontal or vertical deflection amplitude according to the characteristics of a video signal. SOLUTION: A decoder 41 connects the signal of a terminal 43 with a terminal 46, and connects the terminal 46 through a resistance 50 with a feedback input terminal 48 of a vertical deflection circuit 11 by the high level signals of terminal A and B. Terminals 44, 45, and 47 are also connected through resistance with different resistance values. Raster height is decided according to the value of the resistance between the movable arm of a manual raster height adjusting resistance 42 and the feedback terminal 48 in a feedback path, and the decoder 41 controls a vertical raster size according to a size signal applied through the terminals A and B. Then, for example, all the change of deflection currents caused by the fluctuation of a power supply voltage is compensated by the feedback circuit of the vertical deflection circuit 11.  Therefore, even at the time of selecting any height for the raster height, stability can be maintained.

Title: Outer circumference driving type magnetic disk unit
Inventor: TOKUYAMA MIKIO
IPC: G11B33/14
Filed: 1989-07-01
Abstract: PURPOSE:To prevent dust from being stacked to a magnetic disk or a magnetic head and to improve the reliability of a magnetic disk unit by providing a means to generate a circulating air current with the rotation of the magnetic disk and a dust collecting filter in the middle of the circulating air current. CONSTITUTION:A disk 1 is rotated by attracting force between a magnet 11, which is fitted to the outer peripheral surface of an outer peripheral wall part 4 in a disk supporting member 3, and a stator 23 provided in the inner circumference of a still member 22. Accordingly, air is moved to the outer circumference part of the disk by centrifugal force with the rotation of the disk 1 between the disks 1, between the disk 1 and disk supporting member 3 and between the disk 1 and a second disk supporting member 5. Then, the rise of still pressure is generated to be balanced with the centrifugal force. A filter 101 is set near an opening end on the inner circumference side of a duct 100. Accordingly, the air between the disks flows from the outer circumference side of the duct to the inner circumference side and the air current including the dust passes through the filter 101 and becomes clear air. Thus, the dust is not stacked to the magnetic head or the magnetic disk, etc., and the reliability of the unit can be improved.

IPC: G03G15/20
Filed: 1990-06-28
Abstract: PURPOSE:To prevent a wrinkle from occurring by giving the large difference of linear speed to a large-sized transfer paper in which the wrinkle easily occurs. CONSTITUTION:The diameter of a fixing roller 5 at an optional position on a roller shaft between the center part 5a and the end part 5b of the roller 5 is taken as Dn-1 and the diameters of the roller at two positions successively spaced at fixed intervals (t) toward the end in the shaft direction from the above position are taken as Dn and Dn+1. The respective diameters of the roller Dn-1, Dn and Dn+1 are selected so that Dn-Dn-1<Dn+1-Dn may hold among the diameters of the roller. In other words, the fixing roller 5 has such a shape that the rate of increase of the diameter of the roller becomes higher from the center part to the end part. Thus, the difference of linear speed between a center and both side images is made larger in the large-sized transfer paper 7 shown by a broken line than a small-sized transfer paper 6 shown by an alternate long and short dash line in comparison with the case of a conventional drum-like fixing roller.

Abstract: PROBLEM TO BE SOLVED: To make it possible to easily and effectively connect a measuring electrode to a lead wire by welding the electrode to the lead by percussion welding. SOLUTION: A percussion welding is used to connect a measuring electrode 32 to a lead wire 34, and a duplex energy storage system is preferably used as an excuting welding machine. In this case, the electrode 32 is mounted at one welding head of the machine, and the lead wire 34 is mounted at the other welding head. Then, after charge is stored in a capacitor, the electrode 32 is made to relatively come close to the lead wire 34. An arc is generated by this approach, and the opposed ends of the electrodes 32 and the lead wire 34 exposed to the arc are melted. The both are butted to each other from this state, and brought into pressure contact with each other to complete the welding of the connecting parts 36 of both the members.  The welding conditions such as the welding voltage, the moving speed of the welding head are suitably decided in accordance with the materials and shapes of the electrode 32 and the lead wire 34.

Filed: 1994-07-22
Abstract: PURPOSE: To achieve correct assessment of level of significance by comparing a precursor or metabolite of a marker in body fluid sample under consideration of an age of a pregnant woman in pregnancy of a fetus having abnormality with that of a normal fetus. CONSTITUTION: As a marker affected by the age of a pregnant woman, α- fetoprotein(AEP), for example, is listed. For measuring, blood sample taken in the pregnancy period of the 8th to 13th week is used. A blood serum value of the woman measured for each blood serum marker is divided by an expected median taken for pregnant women of the same age at the time of becoming pregnant without having abnormality to provide a target logarithm MoM. Probability of the MoM value for combination of tested blood serum markers pertaining to multivariate distribution of values taken in normal pregnancy is computed. Probability of each combination of values forming part of the multivariate distribution taken in abnormal pregnancy is computed. A normality- to-abnormality rate (likelihood) is multiplied by an age-related level of significance of women to provide a composite level of significance.

Resistance is given to crystals which are let fall by the partitioning shelves 15 and falling flow is rectified. Consequently, an ascending flow of returning solution and descending flow of crystals flow in opposite direction and come into contact uniformly. Accordingly, the quantity of processing can be increased conpared with conventional devices to obtain specified purity of the product.
