Title: Pattern of seal lip for rotation in both directions
Inventor: ARAI YOSHIO
IPC: F16J15/32
Filed: 1978-09-11
Abstract: PURPOSE: To provide the device the same sealing performance in both directions of the rotation of the shaft by forming the patterns such as the two-layered helical ribs of which inclinations are opposite to each other in the expected contacting width of the lip and the shaft simmetrically with respect to a diameter of the lip.  
     CONSTITUTION: The helical ribs (n) are formed in the upper layer of the range (a) of the hollow cylinder inner peripheral surface (k) on the left half of the lip contacting width, and the helical ribs (L) are formed in the opposite direction in the range (b). Furthermore, the helical ribs (t,T) which are simmetrical with those on the (k) side are formed in the range (a) and the range (b) of the hollow cylinder inner peripheral surface (m) on the right half. When the shaft is rotated in B direction, as the suction P 1  in the range (a) occurs in the right half and the leakage -P 2  in the range (a) and the suction P 1  in the range (b) occur in the left half repeatedly, the suction force P can be expressed by P=P 1 -P 2 +P 1 =2P 1 +P 2 = P 1 +P 3  as a whole. P 3  is the suction force of the seal itself. Also, the same result can be obtained in the A rotation.

Abstract: PURPOSE:To reduce the loss of a power transistor (Tr) by connecting a constant voltage diode between a regulated voltage output terminal and the output terminal of a regulator IC and also connecting a resistor between the output terminal of the regulator IC and a common terminal. CONSTITUTION:A power transistor (PTr)Q is driven and controlled by current flowing into the input terminal 21 of the three-terminal regulator IC2 and its collector current is distributed to the regualted voltage output terminal 30 side and the constant voltage diode CR1 side. When a Zenner current is increased, a load current Io is reduced. To make the three-terminal regulator IC2 operative, its input voltage is higher than it output voltage Vs by 2V or more is a necessary condition, and to make the PTrQ operative, it is necessary to secure 1V at minimum for the difference between the emitter voltage VE and collector voltage of the PTrQ. When the latter condition is formed, said necessary condition will be satisfied. Thus, the voltage between the emitter and collector of the PTrQ can be reduced and the loss can be also reduced.

Title: Obstacle recognition unit for vehicle
Inventor: SHIRAI TAKAMASA
IPC: G01S17/931
Filed: 1994-05-26
Abstract: PURPOSE:To simplify the processing for deciding whether a recognized obstacle is identical to one recognized in the past. CONSTITUTION:A one-dimensional distance data representative of an obstacle, detected through a scanning range finder, in the form of a set of points is received (101), and a set having the longitudinal length of vehicle of 6m or less is recognized (103), as a segment (line segment) on an orthogonal coordinates among a set of integrative proximity points. When a segment does not correspond to an obstacle recognized previously and stored as an object Bi. (111:YES), a new object Bj is prepared (112, 113) for that segment within a range where the total number of the objects Bi, Bj comes within a predetermined range, and a decision is made (121) whether the segment recognized later is identical to a segment recognized as the object Bi. Since the obstacle is recognized as a line segment and many objects Bi are not prepared for a long roadside object, the processing can be simplified.

Abstract: PURPOSE:To facilitate a processing to obtain line width information after thinning a line by adding a contour line group number to each black picture element and executing a thinning line processing for picture reading data. CONSTITUTION:A contour line group preparing part 11 adds the fixed group number to the black picture element to be the boundary of the white picture element for the picture reading data, adds the different group number to the internal picture element to be the boundary for the picture element of the group number, the said operation is repeated until the internal picture element is eliminated, and a result is stored into a grouped data memory part 12. A thinning line part 13 thins the lines of the grouped data, and stores the result to a line-thinned data memory part 14. A distance calculating part 15 calculates the distance between the respective arbitrary picture elements of the line-thinned data from a white area based on the data of the grouped data memory part 12 with the use of the group number added to the line-thinned data. A line width calculating part 16 calculates the line width of each point from the distance obtained by the distance calculating part 15 and the tilt of the line.

Title: Device for maximum sequence distance computer, device for decoding maximum sequence and decoding method
Inventor: RICHIYAADO JII YAMASAKI
IPC: H04L25/497
Filed: 1992-04-07
Abstract: PURPOSE: To provide a computer for maximum likelihood sequence distance used for a sequence decoder that processes a sequence of sampled value from a communication channel or a recorder. CONSTITUTION: The distance computer is used by a maximum likelihood decoder where a 2-state trelis is based on a sequence. This includes the duo binary, di-code or partial response class IV signal system. An alive distance with respect to two stages is proportional to a peak level detected by the state. Thus, the peak level is stored by a peak detector 14 till a level of an opposite polarity is detected and a trelis path is converted into an opposite polarity state. A threshold level to convert a path in a state depends on the peak level in the opposite polarity state and a maximum likelihood threshold level. Since only the peak level of a state is stored, an increase in an absolute value of a non- boundary distance is not a problem.
