Patent EP-0366863-A2 (EP)
Inventor: NAKAZAWA MITSUHIRO
IPC: G01N27/407
Filed: 1989-06-28
Abstract: An oxygen sensor device is disclosed having a glass dome fluid-tightly connected at its circumferential base edge to one surface of an oxygen conductive solid electro­lyte plate to form a diffusion chamber defined by the glass dome and the solid electrolyte plate. The diffusion chamber may be vacant, or may have a porous inorganic material packing layer fixedly disposed in the entire space thereof. Alternatively, the diffusion chamber may have a porous inorganic material semi-packing layer fixedly disposed in an upper portion thereof remote from the elec­trolyte plate, while leaving vacant the remainder of the chamber. The oxygen sensor device is advantageous from the viewpoints of miniaturization, power consumption saving and reliability.

Abstract: The invention relates to an ultrasonic treatment device with a treatment head (1), which consists essentially of a housing (2) and an electromechanical oscillation transducer (3) arranged therein, and with an electrical line (6) introduced into the housing (2) of the treatment head (1) in an insulated and outwardly sealed manner. In order to improve such an ultrasonic treatment device so that the presence of a therapist guiding the treatment head is generally not necessary when the device is used, it is proposed according to the invention that the treatment head should be arranged on a support coil holding it, and at least that part of the housing bearing the oscillation transducer should be pivotable relative to that end piece of the support coil bearing the treatment head, by a limited angular range. <IMAGE>

Abstract: An electronic capacitive ballast circuit for operating a DC discharge lamp, such as a negative glow lamp. The circuit includes a rectifier bridge (D11-D14) intercoupling a ballast capacitor (C10) and the electrodes of the discharge lamp. The rectifier bridge is separated into two halves allowing the discharge current to flow to opposite ends of the filament (34) of the lamp during alternating half-cycles so that the filament (i.e., cathode) is operated in a double hot spot regime. As a result, lamp maintenance and performance are improved.

Abstract: A transducer/recording medium stabilising device for a recording and/or reproducing apparatus having a transducer (2) is disposed in an opposing relationship with a flexible storage disk (1) which is used as an information recording medium. The stabilising device comprises first and second block members (10a,10b) which protrude from a base block member (10) and a static pressure releasing means (16,17) on said stabilising device. If the flexible storage disk is rotated at a high speed with respect to the stabilising device, a negative pressure is formed between the stabilising device and the disk, resulting in that the transducer can be in a constant and stable contact relationship with the disk.

Abstract: A timing measurement system for displaying data path and clock jitter moves an internal copy of the data clock with respect to the incoming data and clock to acquire sets of samples for each data path and the clock at sequential delay intervals. A reference time is established by examining the clock sets and determining skew extremes defined by the times when the values within a set are no longer all at one state and when the values are all at the other state. The skew extremes are averaged to establish the reference time. Likewise each data path set is examined to determine skew extremes, and the skew extremes are displayed as shaded areas with respect to the reference time for each data path. Also the clock signal is converted to a stable clock signal that is also compared in a like manner to the input clock to establish skew extremes that are displayed about the reference time as clock jitter.

Abstract: For an optical communications system for diplex or duplex transmission, especially for the subscriber area, a new multiplexing process, namely, the combination of fiber mode multiplexing and wavelength multiplexing, is reported, i.e., the two signals to be transmitted are transmitted with different fiber modes (LP01, (LP11) and with different wavelengths ( lambda 1,  lambda 2) unidirectionally or bidirectionally via a single waveguide. Fusion couplers with exactly similar fibers (FIG. 3) are used as system components such as multiplexers, demultiplexers, and duplexers when one of the two wavelengths is above and one is below the cutoff wavelength of the coupler waveguide and the transmission waveguide (104, 114); or fusion couplers (21, 31) with dissimilar fibers are used when both wavelengths are below the cutoff wavelength.

Abstract: Verfahren zum Zentrieren des Eidotters eines Eies während des Kochvorganges Um den Eidotter eines Eies (1) während des Kochvorganges zu zentrieren, wird das Ei (1) bei vorzugsweise horizontalliegender Längsachse (2) intervallartig und in jeweils gegenläufigen Richtungen um seine Längsachse (2) gedreht. Dies kann vorrichtungsmäßig durch zwei antreibbare Rollen (3), auf denen das Ei (1) gelagert ist, erfolgen. Dabei wird eine Intervalldauer gegenläufiger Drehungen gewählt, die bezogen auf die Verfestigungszeit des Eiweißes relativ kurz ist, so daß es zu recht häufiger, unterschiedlicher Drehrichtung des Eies (1) kommt. Darüber hinaus werden vergleichsweise hohe Drehzahlen bevorzugt. Diese intensive, gegenläufige Drehung des Eies (1) während des Kochvorganges bewirkt eine optimale Zentrierung des Eidotters und vermeidet darüber hinaus die häufig beobachtete Schichtenbildung bei der Verfestigung des Eiweißes. <IMAGE>

Abstract: In an apparatus for optically recording infor­mation on an information recording medium, information is recorded on the recording medium, upon recording of that information, by directing to the recording medium a laser beam which is intensity modulated in accordance with a to be recorded data and the data is read or eliminated from the recording medium, upon reproduction or elimination of the data, by directing to the recording medium a laser beam of a desired intensity which is maintained constant. This type of recording apparatus undergoes an oscillation, etc., at a recording medium during the recording of information, sometimes destroying already recorded data. An apparatus according to the present invention can prevent infor­mation destruction by normally monitoring a laser beam reflected back from the recording medium and detecting recorded information in the recording medium.

Abstract: A film cassette (1) comprises a spool (5) rotatable in an unwinding direction (U) to thrust a leader section (35) of a film roll (33) coiled about the spool out of the cassette and in a winding direction (W) to rewind the leader into the cassette; a pair of flanges (41, 43) coaxially arranged along the spool (5) to normally permit each of the flanges to be independently rotated relative to the spool in the unwinding and winding directions (U, W) and to radially confine the film roll (33) within skirted peripheries (49, 51) of the flanges (41, 43); and a film stripper (67) received between the leader (35) and the next-inward convolution (39) of the film roll (33) to free the leader from the flanges by inducing the leader to flex the flanges (41, 43) slightly away from one another at their skirted peripheries (49, 51) responsive to rotation of the spool (5) in the unwinding direction (U). According to the invention, at least one (43) of the flanges (41, 43) can be fixed to the spool (5) to make the fixed flange rotate in unity with the spool when the spool is rotated in the unwinding direction (U), to improve the ability of the spool to thrust the leader (35) from the cassette (1). Conversely, the fixed flange (43) can be released from the spool (5) to permit it to be independently rotated relative to the spool when the spool is rotated in the winding direction (W), to generally ensure the leader (35) will be rewound within the skirted periphery (51) of the flange.
