Filed: 1994-10-03
Abstract: An apparatus for plugging the interior of a pipe that is penetrated by an axis opening including an upright tubular plugger housing attachable at its lower end to have communication with the interior of the pipe through the opening. An elongated vertical cylindrical control bar is provided with a plugger at its lower end, the plugger being positioned through the opening into the interior of the pipe to close against further flow of fluid through the pipe. A jack is affixed to the plugger housing upper end and telescopically receives the control bar, the jack being pivotally affixed to the housing so that the control bar, having a plugger on the lower end thereof, can be pivoted relative to the housing and thereby relative to the pipe for proper positioning of the plugger in the pipe. The jack serving to axially downwardly or upwardly advance the control bar so that a plugger can be installed or removed from a pipe, the jack providing force to expand a sealing cup on the plugging head to seal the inside of the pipe. A control bar clamp and latch are used for locking the plugger head in the plugging position.

Title: Driving device for a bicycle

Abstract: A travelling driving device for a bicycle capable of increasing rotational torque of a chain wheel (6) using pedalling cranks without elongating a crank arm is disclosed. 
     This device is borne by a bearing (2) disposed on a frame (1) of the bicycle and has an eccentric plate (5) put on a rotating shaft (3) having cranks (4) with pedal (4a). This eccentric plate (5) is secured to a frame member (1) of the bicycle through a stay portion (8). The chain wheel (6) is put rotatably on the outer periphery of the eccentric plate (5) through a ball bearing and a working plate (9) secured to the rotating shaft (3) is linked to the chain wheel (6) by linking members (10, 11). 
     When the rotating shaft (3) is rotated by pedalling action of the cranks (4), rotation is transmitted to the chain wheel (6) through the working plate (9) and the linking members (10, 11). Since the chain wheel (6) is rotated in an eccentric state with respect to the rotating shaft (3), it can be rotated with a rotation radius smaller than a chain wheel having no eccentric mechanism and as the result, rotational torque of the chain wheel (6) is increased, depending on eccentricity length.

Abstract: A stepper motor of the permanent-magnet sheet-metal type is constructed of a number of modules, simplifying assembly. The modular parts include a stator (28) having integrally-moulded winding bobbins and pole pieces. A rotor (30) mounted in the stator includes a barrier member which separates a plastic, threaded hub moulded interiorly from a permanent magnet moulded exteriorly. A shaft (22) having a first threaded end (66) rotatably engaged with the interior of the rotor hub has a rectangular central portion extending through a rectangular opening of the stator to convert rotary motion of the rotor to linear motion of the shaft. An opposite end of the shaft includes a moulded head (70b) and a tubular shield (72) extending from the head. This shield and a tubular portion of the stator moulding define a labyrinthal passage which inhibits the passage of contaminants into the rotor. A housing of the motor and a rotatably attached flange (24) include engagable portions to lock the flange at a desired angular position.

Abstract: A fingerprint detector that uses a skin resistance sensing array for producing a sample trajectory signal when a fingertip is moved across the sensing array surface. The sample trajectory signal represents the electrical conductance changes in the resistance of ridges and valleys of the fingertip. The fingerprint detector also includes a sampling circuit coupled to a processor. In addition, a technique is disclosed for detecting and verifying a fingerprint by moving a fingertip relative to the skin resistance sensing array. The sample trajectory signal produced is translated into a digital signal by the sampling circuit. The processor receives the digital sample trajectory signal for comparison with a known reference trajectory signal. The processor produces a verification signal if a threshold probability that the same fingertip generated both signals is exceeded. The reference trajectory signal is stored in a memory integrated into the device, or is provided from an external storage device through a data interface.

Abstract: ISO/IEC have standardized a video bit stream representing a compression method for standard resolution as well as high resolution video signals and pictures, the so-called MPEG-2 standard. MPEG-2 provides for three different picture coding types: Intra, Predicted and Bidirectionally predicted or interpolated frames or fields. In P and B frames or fields macroblocks can be coded intraframe or intrafield, respectively, if motion prediction does not give good results. The decision has to be made in the encoder with criteria to be determined by the implementation. In addition, MPEG-2 allows for frame or field based DCT which requires sorting of lines and another decision to be made by the encoder. 
A real-time MPEG-2 video encoder has been developed based on a set of dedicated IC designs. The processing functions are organized in three main ICs or stages. A preprocessor contains all input and pre-processing functions like picture format conversion which are required for data compression and a coarse and fine motion estimator contains all motion estimation and motion prediction functions. 
The bit stream encoder includes all bitstream generation for MPEG-2 encoding like DCT (420), quantizer (430), inverse quantizer (431), inverse DCT (421), zigzag scanning (412), and RLC/VLC encoding (422), but does not include motion prediction. This bitstream encoder uses pipeline processing and contains a multi-purpose bit stream assembling stage (432).

Abstract: According to the present invention, in a heating
apparatus (1) having a viscous heater (9) using viscous fluid
for heating cooling water, when an engine rotational speed is
lower than a set rotational speed relative to a temperature of
viscous fluid, a viscous clutch (7) is turned on to transmit a
rotational driving force of the engine to a rotor (53) of the
viscous heater. In this way, a shearing force is applied to
the viscous fluid in the heat-generating chamber (50), and the
circulating cooling water is heated by generated heat of the
viscous fluid to improve the heating capacity. When the engine
rotational speed is higher than the set rotational speed
relative to a temperature of viscous fluid, the viscous clutch
is not turned on. Therefore, the rotational driving force of
the engine is not transmitted to the rotor of the viscous
heater, so that the shearing force is not applied to the
viscous fluid to prevent the oil temperature of the viscous
fluid from increasing excessively higher than 200 °C.

Abstract: A pitch lag coding device and method using interframe correlation inherent in pitch lag
values to reduce coding bit requirements. A pitch lag value is extracted for a given speech

speech, LPC analysis and vector quantization are performed for the whole coding frame. The
LPC residual obtained for each frame is then processed such that pitch values for all
subframes within the coding frame are analyzed concurrently. The remaining coding
parameters i.e., the codebook search, gain parameters, and excitation signal, are then analyzed
sequentially according to their respective subframes.
