Title: Method and equipment for improvement of reliability of data storage device
Inventor: RISA FUREDERITSUKUSON
IPC: H03M13/31
Filed: 1995-03-09
Abstract: PURPOSE: To improve the reliability of a transmitter while using a binary data as a code word on a partial-response-channel by employing a trellis code, in which a minimum distance between the output sequence of the partial-response- channel having a limit output is increased. CONSTITUTION: A binary symbol string type input data is transmitted to a decoder 11 from a bus 10, and the decoder 11 generates a binary symbol sequence having an algebraic limitation, and inputs it to a partial-response- channel 12 having a system polynomial displaying a channel memory. The output sequence of the channel 12 is contaminated by noises, and detected by a change Viterbi detector 13. The detector 13 computes and predicts a most- possible coded sequence from the channel output sequence. A decoder 14 recovers an original input data by the prediction, and outputs it to a bus 15. The time of a trellis is changed so that all output sequences satisfying no algebraic limitation specified to a tracked algebraic attribute value is eliminated from the trellis at the tail of a word code.

Filed: 1978-04-25
Abstract: PURPOSE: To achieve forced fluid lubrication for the bearing, without providing a special flow passage to the bearing, by making a crevice between the outer wall of the circular opening in the pump casing and the first and the second bearing parts member outer peripherals.  
     CONSTITUTION: Through the crevice between the circular opening 6 in the pump casing 1 and the ecdentric ring 22 and the outer peripherals of the first and the second bearing members 13, 21, the fluid is sucked in to the fluid passage 24 and is pressed on the fluid passage 25 side. The fluid flows through the hole 11 on the first bearing member 13 side into the magnet chamber 12, and flows further through the crevice between the bearing 14 and the shaft 30 and the slit 18 in the end surface bearing 17, and then, the fluid is returned to the pump chamber through the space between the side plate 34 and the first bearing member 13. Also, the second bearing member 21 side generates the similar flow through the crevice 42 in the cap. By so constituting, the forced lubrication to the bearing becomes possible without providing any special passage.

Title: Fuel cell and electrolytic cell and cooling and dehumidifying method therefor
Inventor: WATANABE MASAHIRO
IPC: H01M8/02
Filed: 1996-03-07
Abstract: PROBLEM TO BE SOLVED: To efficiently cool and dehumidify electrodes by using a separator plate in which cathode and anode reaction gas supplying grooves are arranged in parallel in one and the same plane. SOLUTION: In this cell, separator plates having anode and cathode reaction gas supplying grooves 5A, 5C, 5C' arranged in parallel in one and the same plane through a metal thin sheet or a conductive resin thin sheet are layered between respective neighboring electrodes. The electrodes are cooled and dehumidified by passing a reaction gas to the cell having such a structure. That is, the reaction gas (oxygen or air) is made to work also as a cooling medium (gas). Steam produced by reaction by introducing a large quantity of the cooling gas is smoothly diffused in the cooling gas and quickly discharged outside of the cell together with the cooling gas, so that saturation degree of steam in cathode fine pores is lowered and the dew point is lowered more. Consequently, even if cooling is carried out, dew drops are not formed.  Moreover, since the reaction gas supplying grooves are arranged in one and the same plane, the thickness of the grooves is lessened to a half and the whole body is made to be compact.

A use right of a bus is given to a bus master A1 to An that has the highest priority among sets of bus masters A1 to An that request bus use based on priority information of one selected set. Thereby weight is given to assignment of bus use right of the bus masters A1 to An and also, the highest priority is set to any set of priority information in all the bas masters A1 to An.

Filed: 1987-03-06
Abstract: PURPOSE:To improve heat efficiency with the secondary combustion of unburnt material and eliminate labor required for cleaning without sticking of the unburnt material to pipings and walls by introducing catalysts promoting the secondary combustion of unburnt material into a fluidized bed. CONSTITUTION:High temp. exhaust gas flows in from the inflow port 2 of a heat exchanger mainbody 1 and is brought in a uniform direction by a per forated gas distributing plate 3 and then is blasted up into the upper part of the exchanger 1. Fluidized material such as quartz sand, etc. is blasted by this gas and a fluidized bed 4 is formed. Heat medium such as water, etc. flowing through a heat exchanging piping 6 in the bed 4 is heat-exchanged with the exhaust gas. At that time, catalysts 5 are floated and scattered in the bed 4 and are brought in contact with the unburnt material of fuel contained in the exhaust gas and the unburnt material is activated and burnt. Thereby, the unburnt material is brought in secondary combustion to improve heat efficiency. Sticking of the unburnt material to pipings and inner walls is eliminated and labor required for cleaning can be saved.

Abstract: PURPOSE:To make it possible to fit a webbing on the body of a passenger and to prevent a seat back inclined forward from damaging a buckle body, by supporting the buckle body to a stoke, rotatably in both longitudinally and widthwise directions. CONSTITUTION:In a free-state condition, a buckle body 3 is supported on the upper end of a stoke 2 in a stand-up condition by means of a coil spring 35, and may be rotated forward of a seat within a range from a position where a stopper 32 abuts against one side surface 2a of the stoke 2 to a position where one of projections on one buckle frame 6 abuts against the other side surface 2b of the stoke 2, overcoming a coil spring. Accordingly, when a seat back is inclined forward, the buckle body 3 is inclined forward, following up the seat back, and therefore, both are prevented from being damaged. Further, the buckle body may be rotated inward of the seat until the inclined surface 16 of a collar abuts against the outer surface of the stoke 2, thereby it is possible to fit the webbing, closely to a passenger.
