Title: Rolling bearing
Inventor: TAKEMURA HIROMICHI
IPC: F16C33/32
Filed: 1997-01-24
Abstract: PROBLEM TO BE SOLVED: To suppress early peeling due to high vibration and high load as much as possible and improve the durability of a rolling bearing by specifying a bulk density ratio of bulk density of a rolling body for bulk density of at least a fixed ring of the fixed ring and a rotary ring. SOLUTION: If bulk density ratio pc/pa exceeds 0.45, the weight of a rolling body becomes too large when compared with the weight of a fixed ring (outer ring), thereby causing the peeling in the fixed ring. If bulk density ratio pc/pa drops below 0.25, the weight of the rolling body for the outer ring is too light, thereby reducing the strength of the rolling body on the contrary, and there is a possibility that the rolling body causes the peeling in a concentrated manner. Therefore, bulk density ratio pc/pa is set to 0.25<=pc/pa<=0.45. To suppress the occurrence of peeling further, it is preferable that bulk density ratio is 0.31<=pc/pa<=0.42. Moreover, it is possible to reduce the vibration of the rolling body itself by limiting surface roughness of the rolling body σc and a surface roughness ratio σc/σa which is a ratio of surface roughness of the rolling body σc to surface roughness of the fixed ring σa and suppress the peeling of the fixed ring.

CONSTITUTION:The axis 20 of an upward member B is moved to the central direction of predetermined parts 910, 911 to be calked of an oxygen sensor C. The lower tapered ring 1 is pushed by the upper tapered ring 5 downward and the lower dies 3, 4 slide along the inside 11 of the cone and a reference surface 21 and fitted at a position of the axis 20. The upper dies 6, 7 are pushed by the lower dies 3, 4, the inside 51 of the cone is slid upward and fitted to the axis 20. The dies 3, 4 and 6, 7 are gathered simultaneously to the central direction of the predetermined parts 910, 911 to be calked and calked roundly. A round shape is made by a temporary calking to a predetamined position to be calked. Then, normal calking is performed by twice calking force through a 90 degree rotation of the oxygen sensor C. In this way, the predetermined pert to be calked can be calked into an accurate round shape and enough heating impact property can be obtained.

Filed: 1979-03-02
Abstract: PURPOSE:To reduce the fault occurrence probability of the compensator by fixing the optimum phase shift amount for the phase shifter of the interference offset circuit and then decreasing the number of the driving mechanisms. CONSTITUTION:Polarization converter 3 and interference offset circuit 11 are installed to the communication system in which two circular polarized waves which turn into the opposite directions to each other or the orthogonal double linear polarized waves are used. When the two polarized waves pass through the rain fall region, the incident wave to antenna 1 is turned into two oval polarized waves turning into the opposite directions to each other due to the rain fall region. And one of the two polarized waves is converted into the main polarized wave in the form of the linear polarized wave which coincides with the X axis of polarizer 4, and thus the other polarized wave is extracted as the interference wave from the Y terminal direction of polarizer 4 respectively. Then phase shifter 12 of circuit 11 is fixed to the optimum phase shift amount. As a result, the number of the driving mechanisms can be decreased along with reduction of the fault occurrence probability.

Abstract: PURPOSE: To make possible uniform good beads on both of front and back faces to be obtained, by employing copper or copper-alloy for the backing strip, and the composite welding core wire containing the flux, and by forming the slag between the backing strip and the sealing bead.  
     CONSTITUTION: A plate of copper or copper-alloy, being provided with the groove 8, is employed for the backing strip 7, and the butt face of the material 1 to be welded is fitted and set onto the groove 8. Then, the welding is carried out with the composite core wire 6 containing the flux. Thereupon, the melting point of the contained flux is lower than that of the metal of the core wire 6, so that the flux melts in advance and forms the sealing slag 9 in the groove 8. Next, following to this slag 9, the molten metal flows into the groove 8 and forms the sealing bead 3. Hereupon, this sealing bead 3 is not quickly cooled by the copper plate 7, so that it forms a smooth surface. Moreover, a part of the flux forms a surface slag 10 on the surface bead 4, so that the uniform good welding beads can be obtained on both of front and back faces, and the quality of weld is improved.

Abstract: PURPOSE:To form a diffused layer having different layer resistance and diffusing depth by one diffusion treatment by selectively forming an oxide preventive layer on an impurity glass layer formed on a semiconductor substrate surface and diffusing in an oxide atmosphere. CONSTITUTION:Glass layers (such as, phosphorus glass) 13, 14 containing impurity are formed in a thickness of approx. 1,000-14,000Angstrom  on a P type Si substrate 11. After an oxide preventive layer 12 of Si3N4 or the like is subsequently selectively formed only on a desired region, it is diffused at 800-1,100 deg.C in oxide atmosphere such as oxygen, steam or the like to form diffused layers 15, 16 having different diffusion depth. Since an oxide film 17 is formed on the region where no oxide preventive layer 12 exists at the time of diffusing in this manner, the diffused layer 16 under this region is so formed as to be shallower in depth and lower in concentration than the layer 15. Accordingly, diffused layers having different layer resistance and diffusing depth can be formed by one treatment with preferable reproducibility.

IPC: G05B1/01
Filed: 1987-02-05
Abstract: PURPOSE:To vary a set counting speed with pressing pressure by using a switch whose contact part varies in resistance with the pressing pressure and a voltage- controlled oscillator. CONSTITUTION:A control command is set by pressing the switch 1. The contact of the switch 1 has characteristics of variation in the resistance value with the pressing pressure. The contact of the switch 1 is connected to a conversion part 2 and its resistance variation is converted into voltage variation. This voltage variation is applied to the voltage-controlled oscillator 3, whose oscillation frequency varies. A counter 4 operates according to the oscillation frequency of the oscillator 3 as a clock to count the signal of the oscillator 3. A display part 5 displays the counted value of the counter 4 and its output 6 is an output signal for setting the counted value of the counter 4 as the control command. Thus, the set counting speed can be varied with the pressing pressure and a setting time is shortened and adjusted finely.
