Patent EP-0461254-A1 (EP)
Inventor: MIYATAKE TSUTOMU
IPC: G01B11/00
Filed: 1989-12-28
Abstract: This invention relates to a lens system having chromatic aberration on the axis of a double-focus detector which utilizes chromatic aberration. One focal plane of the lens system consists of a light image forming plane of a short wavelength corresponding to a first object which is, for example, a mask and the other focal plane consists of the same image forming plane of a wavelength having a predetermined band corresponding to a second object which is, for example, a wafer. The first object is illuminated with the light of a wavelength shorter than 500 nm and the second object is illuminated in a predetermined band of wave-lengths greater than 500 nm.

Abstract: On a mis au point un moteur osmotique amélioré. Ledit moteur osmotique est adapté pour être utilisé avec une seringue à entraînement osmotique utilisable pour acheminer un agent bénéfique tel qu'un médicament, à un rythme prédéterminé pendant une période de temps prolongée. Ledit moteur osmotique comporte une paroi extérieure (12) définissant un compartiment contenant un soluté osmotique (17). La paroi comprend une matière fine perméable et/ou microporeuse, perméable à un liquide externe tel que de l'eau, mais imperméable au soluté. Dans ladite paroi est ménagé un orifice d'acheminement (13). On a prévu un support (14) de paroi non dissoluble de forme annulaire, afin de maintenir la forme dudit moteur lors de son utilisation. Ledit support de paroi présente également un passage d'écoulement de fluide ouvert s'étendant de la partie de paroi semiperméable vers l'orifice d'acheminement. Ledit passage d'écoulement de fluide ouvert réduit au minimum le temps nécessaire pour que le moteur commence à pomper.

Title: An improved chassis frame for a wheeled motor vehicle.
Inventor: TOWNSEND JOHN A
IPC: B62D25/20
Filed: 1990-01-25
Abstract: A chassis frame is provided with a reinforced floor section and barrier sections fixed to the floor section in longitudinally spaced relationship to one another. Door openings are formed between the barrier sections to either side of the frame. The floor section is of a reduced width and the barrier sections include outwardly convex curvilinear side portions extending laterally relative to the floor section. Door panels are carried by the side portions for slidable movement relative thereto in a curvilinear path defined by the shape of the side portions between extended positions bridging the door openings and retracted positions stowed beneath the floor section. The door panels are tension, compression and torsion resistant and, when in the extended positions, mutually engage the floor section and the sides of the door openings to impart rigidity to the frame.

Title: Improved method of and means for providing information to edit a video tape.
Inventor: ROGGENDORF PETER
IPC: G11B27/024
Filed: 1990-05-10
Abstract: A method of and apparatus for editing half-inch tape used for home recording of video material applies pulse-width modulation to prerecorded synchronizing pulses in predetermined time intervals. The interval is started with an eleven-bit header that is compatible with that of a commercially available system known as the VASS system. Time blocks are then encoded by pulse-width modulation with information identifying the particular recording session and the number of elapsed seconds minutes and hours since the beginning of the session. A check code completes the modulation during the interval for television systems such as PAL and SECAM that are adapted for fifty-Hz operation. For systems such as NTSC that operate at sixty Hertz, a ten-bit dummy code is added to complete the two-second interval. The code is entered without writing over the leading edge of the prerecorded synchronizing pulse, allowing the timing of those pulses to continue without interruption. Using this system, an editor can locate any desired interval and can then locate an individual frame within that interval by counting synchronizing pulses. The apparatus of the invention inserts and detects the header, inserts and detects the address code, inserts time signals in sequence, and detects a selected time interval and frame within that interval. An electronic circuit processes signals derived from the tape for input to a microprocessor which controls displays, insertion of codes, and advancing to a chosen edit location.

Abstract: The sensor comprises an optoelectronic probe unit (3) and a transparent gauge (2) with two parallel graduated tracks (4, 5). One track (5) has a constant pitch incremental graduation and the other track (4) has a pseudo-random graduation forming binary coding bits constituting a continuous series of words which are different from one another, the width of a bit being a function of the pitch of the incremental graduation. The incremental track (5) is read through a probe reticule (9) by photodetectors (8) which are phase-shifted by 90 DEG  electrically in order to permit interpolation into the pitch of this track. The track (4) with pseudo-random graduation is read by a CCD detector (11) through an image-magnifying lens (13). The signals generated are processed by circuits (15a, 15b) combining the information extracted from the two tracks of the gauge.

The second control circuit (244) produces a variation from the base frequency determined by the first control circuit 234. Thus, the cutoff frequency of the high pass filter (218) will always be proportional to that of the low pass filter (216).
