20080205813 | Tapered roller bearing - A tapered roller bearing includes an inner ring, an outer ring, a plurality of tapered rollers, and a cage. The cage includes a large diameter-side annular section, a small diameter-side annular section, and pillar sections connecting the large diameter-side annular section and the small diameter-side annular section and forming pockets retaining the tapered rollers. The radially inner surfaces of the pillar sections are disposed closer to the center than a pitch circle of the tapered rollers and are inclined from the small diameter-side annular section toward the large diameter-side annular section, thereby forming guide surfaces that guide lubricating oil toward the large rib. Roller holding portions are formed on side portions of the pillar sections so as to protrude along the outer peripheral surfaces of the tapered rollers to a position located at the outer side in the radial direction than the pitch circle. | 08-28-2008 |
20080219606 | Tapered roller bearing - A tapered roller bearing includes: an oil guide member that opens and closes an annular opening between an outer peripheral surface of a large rib of an inner ring and an outer ring and is mounted on the large rib; and a discharge port that discharges, along the outer peripheral surface of the large rib, lubricating oil and is formed through an inner peripheral portion of the oil guide member. The oil guide member includes a closing portion for closing the annular opening. When a fluid pressure of the lubricating oil which flows through pockets of a cage toward an inner peripheral surface of the outer ring is below a predetermined values, the closing portion closes the annular opening and guides the lubricating oil toward the discharge port. When the fluid pressure exceeds the predetermined value, the closing portion opens the annular opening. | 09-11-2008 |
20090028486 | Tapered roller bearing - Guide grooves for guiding lubricating oil from a small rib-side end portion of an inner ring to a large rib-side end portion thereof are formed at an inner periphery of a cage. | 01-29-2009 |
20100172607 | BEARING STRUCTURE AND MANUFACTURING METHOD THEREOF - To provide a bearing structure in which the processing is easy, and the manufacturing cost can be reduced. | 07-08-2010 |
20110064350 | SPLIT OUTER RING, SPLIT ROLLING BEARING USING THE SAME RING AND CONSTRUCTION AND METHOD OF MOUNTING THE SAME ROLLING BEARING - There are provided a split outer ring which can suppress the reduction in durability and which can suppress largely the generation of noise or vibration which is caused in association with the passage of rolling elements over a mating surface and a split rolling bearing which employs the same outer ring. | 03-17-2011 |

20090323955 | DATA TRANSMITTING APPARATUS AND DATA RECEIVING APPARATUS - In secret communication using a Y-00 protocol, provided is a data communication apparatus which realizes reduction in a random number generation speed by using a plurality of random number generators, and which also ensures security. The data communication apparatus includes: a plurality of random number generation sections | 12-31-2009 |
20100158249 | DATA TRANSMITTING APPARATUS AND DATA RECEIVING APPARATUS - Provided is a data communication apparatus which significantly increases time necessary for an eavesdropper to analyze cipher text and which is superior in concealability based on astronomical computational complexity. A multi-level signal, which is generated by using data and key information, has a minor amplitude modulation, which is based on a random number signal generated on a transmission side, overlapped thereon, and is then transmitted. On a receiving side, instead of data decision, three types of decision, i.e., “1”, “0” and “decision impossible”, are performed on a random number signal by using two threshold values whose interval is significantly wider than a modulation amplitude based on random numbers. Information of a bit whose decision is performed successively is returned to the transmission side, and the bit is used commonly as a new key. Accordingly, in a single transmitting/receiving apparatus, cipher text transmission and key distribution can be realized simultaneously. | 06-24-2010 |
