Abstract: Provided is a signal reproducing circuit for an optical disc player comprising a multidivisional photodetector (9) with photoelectric converting elements (D1, D2) in a preceding side and photoelectric converting elements (D3, D4) in a succeeding side relative to a proceeding direction of pits (11) of an optical disc (10), a variable delay circuit (50) for delaying outputs from the photoelectric converting elements in the preceding side, a circuit (51, 52, 53; 60) for detecting a time difference between an output from the photo electric converting elements in the succeeding side and an output from the variable delay circuit, and a circuit (C22, VC1 to VC3) responsive to an output from the time difference detecting circuit for changing a delay time of the variable delaying circuit. The signal reproducing circuit further comprises a circuit (72, 72′) for amplifying and correcting high frequency components of signals reproduced by the photo detector in response to the output from the time difference detecting circuit. This structure extends reproduced frequency band, improves high frequency characteristic of the video signals reproduced from the optical disc and supplies video signals having superior frequency characteristics.

Abstract: A method for assay for an unknown enzyme suspected to be present in a liquid includes signal amplification by use of a second enzyme and a blocked modulator for the second enzyme. Unknown enzyme in the liquid removes a blocking group from the blocked modulator. The resulting modulator activates or inhibits the second enzyme which catalyzes an indicator reaction in which a substrate is converted to a product. The presence or absence of the unknown enzyme in the liquid is indicated by a signal, such as a color change or a rate of color change, associated with the indicator reaction. The concentration of the enzyme in the sample may be determined by the measurement of the signal. The invention includes a kit of materials useful for performing the method of the invention.

Abstract: Laminates are provided of at least one polynorbornene prepreg comprising a substrate coated with a polynorbornene secured to a conductive surface, such as copper having an etched matte texture thereon. Adhesion between the polynorbornene prepreg and the conductive surface is improved by coating the conducting surface with as silane coupling agent and/or by providing polyolefin film therebetween. To improve or reduce the dielectric constant, polyolefin powder can be placed in the dipping bath in the preparation of polynorbornene prepregs. Epoxy prepreg can also be incorporated into the laminates. Multi-layer laminates can be provided of alternating or non-alternating epoxy prepregs and polynorbornene prepregs. The prepregs are made by a process which includes an adhesion promotion step wherein the prepreg, preferably polynorbornene prepreg, prior to lamination, is pretreated with a silane adhesion promotion agent. One or more copper foils can also be employed between exterior surfaces of the prepregs, at the interface between the prepregs, as well as on the exterior of the laminates. The copper films can be etched to form patterns such as those suitable for printed circuit wiring boards.

Abstract: The present invention relates to photosensitive compounds that generate free radicals upon exposure to light. Halomethyl-1,3,5-triazines are known to be initiators for a number of photochemical reactions. However, the spectral sensitivity of these initiators is limited. It would be desirable to incorporate a sensitizer moiety into a halomethyl-1,3,5-triazine to increase the spectral sensitivity thereof. 
     This invention provides radiation-sensitive organo-halogen compounds having a photo-labile halomethyl-1,3,5-triazine moiety and at least one sensitizer moiety within one molecule. The compounds of this invention are good photoinitiators, and compositions containing them can be used in printing, duplicating, copying and other imaging systems.

Abstract: An improved gerotor device is disclosed, usable as either a pump or a motor, of the type including a gerotor gear set (17), and a movable valve member which may have either purely rotary motion (55), or may have both orbital and rotational motion (127). The valve member defines two groups of valve ports (63,65; 163,165) communicating with an inlet port (57) and an outlet port (61). The movable valve member is in sliding, sealing valving action with an adjacent stationary valve plate (19′; 119′) which defines a set of stationary fluid passages (67a-67g; 167a-167i) which communicate with the gerotor volume chambers (29a-29g). The stationary valve plate, in accordance with the invention, also defines a plurality of secondary fluid passages (77a-77g; 177a-177i) each of which is diametrically opposite one of the primary fluid passages (67a-67g; 167a-167i). The primary and secondary fluid passages are interconnected by cut-out portions within the stationary valve plate, defining fluid passages, thus effectively doubling the orifice area during valving action, and substantially reducing the no-load pressure drop when the device is being used as a motor, or substantially reducing the tendency toward cavitation when the device is used as a pump.

Abstract: The device described for checking the illuminating system (1) of an endoscope allows both the lamp (7) itself and the optical-fibre cable (2) to be checked for their functional state. For this purpose, the device has a beam splitter (9), which is arranged in the beam path of the lamp (7) and feeds a portion of the quantity of light emitted by the lamp to a recording device (11). A recording device (12) provided with an attachment for accommodating the distal end of the optical fibre (2) receives the light quantity emerging from the optical fibre cable. Between the signal derived therefrom and the signal generated by the recording device (11), the transmittance is determined by forming the quotient in a computing circuit (13) and output via a display (5). In this way, it can be detected whether the transmission of the optical-fibre cable (2) permits adequate illumination of the objects to be inspected, or whether the optical fibre cable has to be replaced.
