Title: Rolling bearing
Inventor: IKEDA NORIFUMI
IPC: F16C33/32
Filed: 1998-12-24
Abstract: PROBLEM TO BE SOLVED: To restrain abnormal discharge by electrification of a rotary body and scavenging of a foreign matter by electrification of a rolling body itself by constituting an inner ring and an outer ring of a conductive material and the rolling body of conductive ceramics. SOLUTION: A ball bearing is constituted of an outer ring 1, an inner ring 2, a rolling body 3, a cage 4 and a seal 5. Among these, the outer ring 1 and the inner ring 2 are made of stainless steel, and the rolling body 3 is constituted of conductive ceramics. Thus, the whole bearing has electric conductivity, a rotary body supported by a bearing can be electrically continued with a fixed side device, and the rotary body can transmit static electricity and intentionally imparted electric charge to the fixed side device without accumulating these. Because of the ceramic rolling body, the service life of the bearing can be lengthened, and since electrification of the rolling body itself can be restrained, capture of static electricity of a foreign matter in oil and the atmosphere can be reduced, and mixing of the foreign matter in the bearing inside can also be restrained.

Title: Soft discrimination viterbi decoding method
Inventor: ABE MASAMI
IPC: H03M13/23
Filed: 1990-12-19
Abstract: PURPOSE:To decrease a bit error rate of an original signal by converting a phase of a carrier detected at a receiver side into a bit margin and using the bit margin for soft discrimination Viterbi decoding when a convolution code is sent in a differential type PSK modulation system. CONSTITUTION:Two phases closed to prescribed phases sent in the pi/4 shift DQPSK system are selected in the step S51 in the order of inputted phases of received carriers. A phase margin is calculated in the step S52 in response to the absolute value of the phase shift from a prescribed phase. A phase difference is obtained in the step S53 from two phases selected timewise consecutive. A smaller phase margin used to obtain the phase difference is selected in the step S54 among phase margins. Two phase differences among those having a larger phase difference margin are selected in the step S55. After the margin of a bit string corresponding to the selected phase difference is calculated in the steps S56, S57, the bit margin is corrected in the step S58.

Title: Processing method and device for electrophoresis medium
Inventor: YUTA SHIYUTANGERUBERUGERU
IPC: G01N27/447
Filed: 1990-12-20
Abstract: PURPOSE: To facilitate and automate the successive treatment by carrying a liquid used for treatment along an electrophoretic medium. CONSTITUTION: The liquid in each treatment step is force-fed through an injection pipe 2, carried into a vessel 1 through the hole 6 of a ring piping 3, and carried out through a discharge pipe 4. Since the liquid is passed through the hole 6 of the piping 3 and carried into the vessel 1 by the pressure, it forms one flow. The liquid is introduced at a pressure of at least 60mb. Therefore, an electrophoretic medium is floatingly held in the liquid without being gathered to a grid 5. Thus, the mechanical movement of the electrophoretic medium every step of the following treatment is dispensedwith. The injection and discharge of the liquid are controlled by a proper control device, whereby they can be automated.
