Title: Frame synchronization apparatus
Inventor: SHIINO HARUHIRO
IPC: H04L7/08
Filed: 1996-02-27
Abstract: A frame synchronization apparatus is applied to a TDMA (Time Division Multiple Access) communication system, particularly, one in which a plurality of transmission rates are available.  The frame synchronization apparatus calculates correlations between sampled sequences of a received signal and an assigned sync sequence during the longest or shortest frame period in the plurality of transmission rates.  The apparatus stores positions where the correlations exceed a given threshold.  Then, the apparatus sets a search gate at a position after a lapse of the longest or shortest frame period from each of those positions.  The apparatus calculates correlations between the sync sequence and sampled sequences of the received signal for all the search gates.  The actual transmission rate is determined from the plurality of transmission rates based on a time interval of positions where the correlations beyond a second threshold were detected.          Synchronization is thus established.

Inventor: BRILLANT DANIEL
IPC: F16K11/074
Filed: 1996-03-28
Abstract: A self wear compensating valve for controlling flow of a fluid employs seals for sealing between relatively moving parts.          In one of the parts, an annular recess is formed.  A conformable sealing member is placed in the recess, and a spring biased to expel the conformable sealing member and press it against a sealing surface on the other part is provided.  An O-ring placed on the outside of the conformable sealing member prevents leakage of fluid through the recess outside of the conformable sealing member.  As the conformable sealing member is worn away, after many cycles of the valve, the spring continues to press it against the sealing surface, while the O-ring continues to prevent leakage of fluid outside the conformable sealing member.          A rotary valve suitable for railroad brake applications is provided, which controls flow of fluid from a supply to the brake cylinder, and provides for exhaust of fluid from the brake cylinder.  The valve has a supply port, a delivery port and an exhaust.  In one position, the supply port is connected to the delivery port through a passage in the rotor.   In another position, the delivery port is connected to the exhaust port through a passage in the rotor.  In a third position, the lap position, all the ports are blocked by the relative position of the rotor and the housing.  Proportional control of fluid flow is provided by elongating the ports on the mating surfaces of the rotor and the housing in the direction of rotation.

Abstract: A bath lift features a lifting plate  (16)  connected to a hydraulic  lifting hose  (12)  which raises  it as water  is supplied, and lowers it as water is drained out. Fitted to the underside of the lifting plate (16) is a manual control valve (18), from which a connection hose (20)  leads to the hydraulic lifting hose. A further hose element (24)  of the manual control valve (18)  ends at a coupling element  (22) which serves to connect a pressure-water supply hose.  The manual control valve (18) also has a drain port which, in one operating position of the manual control valve, communicates with the hydraulic lifting hose (12). In the other operating position, the hydraulic lifting hose (12) is connected to the pressure-water supply, and in a neutral central position, the manual control valve shuts off the hydraulic lifting hose from  the  pressure-water  supply  and  the  drain  port.  The lifting plate (16) has a second opening (28) the same size as opening (26), and this is located at the other longitudinal side of said lifting plate (16). Furthermore, an identical arrangement of fixing holes (30) is provided on both sides of this second opening (28). In addition, the lifting plate (16) features a further fixing hole arrangement (44). The second opening  (28)  and the described fixing holes are,  in the standard bath lift design, without function and are covered by a cushion mat. In order to provide the bath lift with a connection  for a hand-held shower  attachment,  a  shut-off spool/slider valve  (48)  is bolted into the second opening (28), which valve (48) features a connection fitting (50) for the shower hose and a connection (46) leading to a manifold (35)  from which a further hose element  (38)  leads  to  a coupling element (40), this latter being connected not to the pressure-water supply but to coupling element  (22)  of the first manual control valve (18). Manifold  (35)  features a coupling element  (36)  for connection of the pressure-water supply. The bath lift can thus be expanded by a retrofit set to include  at  least  one  further  pressure-water  connection, without the need to rework the lifting plate (16).

Abstract: A method of preserving frequency components in digitally sampled signals exceeding a maximum frequency related to a predetermined digital sample interval. The signals correspond to a plurality of sensors positioned at spaced apart locations, and the signals from each of the plurality of sensors are digitally sampled at the predetermined digital sample interval. The method includes the steps of determining time adjustment values corresponding to each sensor which provide amplitude correspondence between each of the signals generated by each of the sensors in response to different propagation times of energy from an energy source to each of the sensors; adjusting a time of acquisition of each digital sample from each of the sensors by applying the corresponding time adjustment value to generate time-adjusted samples; and combining all the time adjusted samples into a combined output signal having a sampling time interval smaller than the predetermined digital sample interval. In a preferred embodiment, the sensors comprise seismic sensors positioned at spaced apart locations. The step of time shifting the signals from the plurality of sensors comprises applying a normal moveout correction to the signals from the plurality of seismic sensors. Digital signal samples to which moveout correction is applied are then positioned in an output buffer in the exact time locations defined by the normalmoveout correction. In the one embodiment of the invention, the step of combining the signals from the plurality of seismic sensors further comprises generating acommon mid-point (CMP) trace stack of the time-adjusted signals from the plurality of seismic sensors.

Abstract: A replacement of cylindrical blades is facilitated. Even if there is a slight displacement  in guide surfaces of a slider,  the displacement is not adversely affected to the displacement of a tip end of each cylindrical blade to thereby dispense with a pad by punching paper with a lower blade and the tip end of the cylindrical blade. A holder (28) in which the cylindrical blade (14) are inserted into through holes (25) and (26) formed in an upper horizontal portion (22) and a lower horizontal portion (23). Thus, it is possible to replace the cylindrical blades (14) by simple steps for inserting and drawing the holder (28). Also, since the up-and-down movement of the cylindrical blade (14) is guided irrespective of the guide portion of the slider (10) by the through hole (25)  formed in the upper horizontal portion (22), the displacement is allowed in the guide portion of the slider (10). Then,  since a swing motion of the cylindrical blade (14) is obviated and the lowering position of the tip end of the blade is accurately determined, it is possible to cut and punch the paper between the tip end of the cylindrical blade (14) and the lower blade (27) to dispense with a pad.
