Abstract: The inside pipe wall of a telescopic vacuum cleaner suction pipe (10) having an outside pipe (11) and an inside pipe (12) has an impressed catch strip (17) with catch recesses (18), with which strip a catch element (35) interacts. The latter can be disengaged against the restoring force of a spring by means of a holding-down device (30) which is actuated by a sliding handle in the axial direction (x) of the pipe. The annular space (R) formed between a cylindrical end widening (13) of the outside pipe (11) and the inside pipe (12) is filled by a tubular guide element (16) for the holding-down device (30), sliding handle (28), catch element (35) and spring (19). The sliding handle (28) and catch strip (17) are arranged on two diametrically opposite circumferential positions of the vacuum cleaner suction pipe (10). 
<??>A constructional simplification and ease of assembly of the vacuum cleaner suction pipe (10) result from the fact that the holding-down device (30) is arranged directly adjacent to the catch strip (17) inside the annular space (R) between the outside (11) and inside pipe (12), that the guide element (16) maintains tension on one end of a bar spring (19) which is wound at least partially around the guide element (16) inside the annular space (R) and couples the movement of the holding-down device (30) and the sliding handle (28), which penetrates the wall of the end widening (13).

Abstract: PURPOSE:To reduce a resistance at the time of injection of a resin, to make a lead frame fix excellently with the resin even if the thickness of the resin in thin and to make it possible to remove completely resin burrs by a method wherein the resin burrs are removed by inserting punches from the direction reverse to the punching direction of leads. CONSTITUTION:Resin burrs 29 are removed by inserting punches 30 from the direction reverse to the punching direction of leads 24 and moreover, the punching surface of a lead frame is face downward and a resin flows in from the direction of the punching surface. Accordingly, even if a resin injection gate is located in a bottom face, the resin can flow in without resistance as shown by arrows and when the leads are punched by the punches 30 from the surface, on which punching burrs 28 are generated, of the lead frame, the resin burrs 29 can be removed excellently using these punches 30 because the burrs 29 are adhered only on the longitudinal side surfaces of the leads 24. Thereby, the fluidity of the resin is improved, the resin can be firmly bonded on the lead parts and the resin burrs can be completely removed.

Abstract: An arrangement for producing a digital signal from an input (e.g., analog) signal obtained from a transmission medium. The arrangement includes a variable equalizer for equalizing the input signal as regards magnitude and phase as a function of frequency to produce an equalized signal, an equalizer control signal generator for generating first and second control signals for controlling the variable equalizer and a detector for producing the digital signal from the equalized signal. The arrangement further includes a bit array selector (i.e., a bit sequence detector) for generating one or two selection signals upon detection of one or more specific bit arrays (i.e., bit sequences) in the digital signal, and a sample-and-hold unit which samples one or more portions of the equalized signal under the influence of the one or two selection signals so as to produce at least one first sample value and at least one second sample value. The first and second control signals are derived in whole or in part from arithmetical combinations of the at least one first sample value and the at least one second sample value. The variable equalizer equalizes the input signal as regards magnitude in response to the first control signal and as regards phase in response to the second control signal.

Abstract: PURPOSE:To largely shorten the moving distance of an attraction collet and to improve the working efficiency of assembling by providing substantially horizontally movably a table plate having a guide hole through which the collet passes between the collet and a lead frame or a substrate at an elevated position. CONSTITUTION:When one semiconductor pellet 8 is supplied to a position directly under an attraction collet 3 by the movement of a tray 6 in a direction of an arrow F, the collet 3 starts moving down thereby to attract the pellet 8. Then, a table plate 4 is so horizontally moved that a guide hole 5 is moved to a position directly under the collet 3. Then, after the collet 3 is further moved down through the hole 5 toward a lead frame 2 in the state that it remains attracting the pellet 8, it releases the attraction, thereby supplying and placing the pellet 8 onto the upper face of a mount at the frame 2. When it is finished and the collet 3 is raised, the plate 4 is so horizontally moved that the hole 5 is moved to a position out of the position directly under the collet, a tray 6 then feeds a next semiconductor pellet 8 to a position directly under the collet 3.

Abstract: The present invention relates to the field of synthetic polymeric microfiltration membrane materials that are fabricated to separate liquids from solids contained therein. One aspect of the invention relates to a sulfone polymer membrane with high surface porosity (high pore density) and distinctive asymmetry that can separate solids (i.e., blood cells) from a liquid (i.e., plasma) without the need for centrifugation. The membrane is further rendered hydrophilic through co-casting the sulfone polymer (which is a hydrophobic polymer) with a hydrophilic polymer, such as polyvinylpyrrolidone. Because of these properties and the fact that it requires only a small amount of the solid containing liquid (i.e., whole blood) to be applied to the larger pore surface, the membranes of the invention are highly useful in testing devices for the quick detection of properties or components contained in liquid samples, such as diagnostic applications (i.e., the detection of physiological conditions (i.e., pregnancy, insulin level, stomach ulcer, and the like) and infectious diseases (i.e., AIDS, hepatitis, and the like)).
