Abstract: In a disc playback device in which a disc cartridge case (C) housing a disc is loaded in a disc cartridge case holder (42) of a main body (D) of the device and this holder is moved from a disc non- playback position to a disc playback position for playing back of the disc, a loading system for a disc cartridgec case comprises a curved surface portion formed in a corner portion on the side of the disc cartridge case from which the case is inserted into the holder and an uncurved surface portion formed in a corner portion on the side opposite to the side from which the case is inserted into the holder. A case erroneous insertion blocking member having an engaging portion is provided on the holder. If the case in its correct insertion posture is inserted into the holder, the engaging portion of the blocking member cooperates with the curved surface portion of the case to permit the case to be inserted into the holder. If the case in an incorrect insertion posture is about to be inserted into the holder, the engaging portion of the blocking member cooperates with the uncurved portion of the case to prevent the case from being inserted into the inside of the holder.

Abstract: Die Erfindung betrifft ein Verfahren zur Isolierung von p-Hydroxybenzaldehyd aus dem durch Oxidation von p-Kresol mit Sauerstoff oder sauerstoffhaltigen Gasen in Methanol in Gegenwart von Na- oder K-Hydroxid und eines Mn-, Ni-, Cr- odr Co-Salzes erhaltenen Reaktionsgemisch. Dabei geht man entweder so vor, daß man dem Reaktionsgemisch Wasser zufügt, die entstehende Lösung erwärmt und das ausgefallene Mn-, Ni-, Cr- oder Co-Oxidhydrat abfiltriert, aus dem Filtrat das Methanol abdestilliert, die zurückbleibende wäßrige Lösung abkühlt und so den p-Hydroxybenzaldehyd als Na- oder K-Salz auskristallisieren läßt. Oder man trocknet zuerst das Reaktionsgemisch durch Versprühen, löst dann die löslichen Bestandteile der Trockensubstanz mit heißem Wasser, filtriert das ungelöste Mn-, Ni-, Cr- oder Co-Oxidhydrat ab und läßt durch Abkühlen des Filtrats wieder das Salz des p-Hydroxybenzaldehyds auskristallisieren. Eine weitere Methode besteht darin, daß man das Reaktionsgemisch mit Methanol verdünnt, das ungelöste Mn-, Ni-, Cr- oder Co-Oxidhydrat abfiltriert, das Filtrat durch Versprühen trocknet, die entstandene Trockensubstanz mit heißem Wasser löst und durch Abkühlen der Lösung den p-Hydroxybenzaldehyd wieder als Na- oder K-Salz auskristallisieren läßt.

Abstract: A multizone test device for the determination of analyte from a liquid test medium upon contact with the liquid test medium and a labeled reagent comprising a chemical group having a detectable chemical property. The test device preferably comprises multilayers including a reagent layer incorporated with an immobilized reagent and a detection layer incorporated with an immobilized form of an interactive detection reagent for the labeled reagent. The immobilized reagent and the labeled reagent comprise specific binding partners which will bind to each other dependent upon the amount of analyte present. Labeled reagent which does not become bound to the immobilized reagent in the reagent layer migrates into the detection layer and becomes bound to and immobilized by the immobilized binding substance therein. As a result, reverse migration of the labeled reagent into the reagent layer is prevented and the detectable physical property provided by the label of the labeled reagent is localized in the detection layer for the precise measurement thereof and correlation to the amount of analyte in the test medium.

Abstract: A scroll compressor (1) is provided of improved compression efficiency in which lubricating oil can pass easily from the higher pressure side to the lower pressure side without reduction in the sealing between the two sides. By injecting sufficient lubricating oil between the scroll members (43, 35), both the sealing and the lubricating between the scroll members (43, 35) are improved. A controlled amount of lubricant is supplied to the interior of the compression chambers without need to provide a separate control mechanism. In the scroll compressor (1), lubrication oil pumped up by the main shaft (25) is supplied through a channel (75) either to the top surface of the frame protrusion (57) which partitions the rear surface of the orbital scroll member (43) into the higher and lower pressure sides, or directly to the lower pressure side.

Abstract: The invention concerns a reaction cell wherein components present in a liquid can be precipitated and separated. Three phases (solid, liquid, gaseous) have been disposed to participate in the process taking place in a reaction tank (30) serving as reaction volume and which phases can react with each other directly or catalytically. The reactions have been disposed to take place mainly by mediation of an array of microbubbles, the solid matter that is formed and/or that is originally present in the liquid being separated by floata­tion with the aid of said array of microbubbles and/or with a vortex separator. The reaction tank (30) serving as reaction volume is conically tapering at least in its lower part (5), this part constituting a vortex separator.

Abstract: In a synchronized digital horizontal deflection system operating at 2xf<sub>H</sub>, a first word (HDPW) is produced that is indicative of the length of one-half the period H between f<sub>H</sub> rate horizontal sync pulses (Hs). A first f<sub>H</sub> rate signal (CMa) that is synchronized to the horizontal sync pulses (Hs) is generated. The first f<sub>H</sub> rate signal (CMa) is time shifted by one-half of the period H, in accordance with the first word (HDPW) to produce a second f<sub>H</sub> rate signal (CMb). The first (CMa) and second (CMb) signals are multiplexed (in 40) for generating a horizontal deflection control signal (CMa, CMb) at 2xf<sub>H</sub> rate that controls the retrace interval timing in a deflection circuit output stage (41).

Abstract: A method for the generation of precise single- and dual-tone multiple-frequency signals using only digital signal processing techniques is disclosed. The frequency, amplitude and cadence of the tone(s) generated are programmable via a microprocessor. The tones generated are suitable for the dual-tone multiple-frequency (DTMF) used in communication networks as well as for tone message and tone ringer functions. The principle of operation is that a triangular wave is produced (820, 826) by the repetitive addition of a user-supplied "delta" value to an accumulator until an overflow condition occurs, and then the delta value is repetitively subtracted from the accumulator until an underflow condition occurs. Next, a trapezoidal wave is produced by multiplying (822, 828) the triangular waveform by 1.5 and truncating the resulting waveform at selectable positive and negative levels. The desired amplitude is then established by multiplication by a selectable attenuation (824, 830) value. A DTMF waveform is obtained by generating two waveforms as just described and then summing (832) the resulting waveforms, producing a waveform of a frequency with less than 1% deviation. An exemplary embodiment illustrates the waveform generation method of the present invention in the audio processor section of a digital subscriber controller.

Abstract: An interface circuit for translating digital signals signifying colors in any of various color formats into analog signals for controlling respective primary colors of a display monitor operating in a standard R, G, B primary color format. The circuit adds a control bit to each digital signal identifying the color format of the signal, and each of the colors signified by respective digital signals are identified by digital words correspon­ding thereto stored in a digital memory. The bits of each stored word control respective levels of analog signal attenuation in analog summing networks for converting each of such words into respective R, G, B analog signals for the video monitor. Changing the value of the control bit changes the word read-out from the memory in accordance with the particular color format of the received digital signals.
