Title: Laminated and grain boundary insulated type semiconductive ceramic capacitor and method of producing the same
IPC: H01C7/115
Filed: 1990-03-20
Abstract: A laminated and grain boundary insulated type semiconductor ceramic capacitor which normally works as a capacitor absorbing noises of low voltages and noises of high frequencies and works as a varistor when high voltage pulses or static electricity noises are applied thereto. The material of the ceramic capacitor is chiefly Sr(1-x)CaxTiO3 by which the material and the internal electrode material can be baked simultaneously in the process of production. A method of producing the same is also disclosed. The reason why the both materials can be simultaneously baked is as follows. A component for changing a material into a semiconductor is added to a Ti-excess of Sr(1-x)CaxTiO3; Mn and Si components are further added which turn into MnO2 and SiO2 respectively during the step of baking; and accordingly grain boundary insulated semiconductor for capacitors is easily obtained only through re-oxidation without the conventional step of surface diffusion of metal oxides. Further, according to the invention, the compact after lamination is calcined in advance in the air to obtain a laminated ceramic capacitor with a varistor function. Problems such as breakage in the internal electrode, delamination, cracks, low density after sintering, and nonhomogeneity of structure of the sintered body are suppressed as far as possible. The capacitor exhibits remarkable improvement in electric characteristics such as capacity, voltage non-linear exponential α, varistor voltage and in reliability. The invention exhibits the greatest features in the material composition and process in regard to the above two points.

A computing means (15) coupled to the transmitter (11) and receiver (12) is adapted to compute the distance from the front of the vehicle to the device (10) and a logic means coupled to the computing means compares the computed distance with a predetermined threshold so as to generate an output signal if the computed distance is less than the threshold.
Patent EP-0512078-A4 (EP)
Title: Precision landing system
IPC: G01S13/91
Filed: 1991-01-25
Abstract: A precision aircraft landing system comprising at least four receivers which are located at different predetermined positions. Each receiver includes a precision timer for measuring the timer interval between the receiver's detection of an interrogation signal and a reply signal from a transponder onboard the aircraft. The system also includes a central processing unit (computer) at a base station which collects the time measurements from the receivers, and calculates the location of the aircraft. Because more than three independent measurements are used, the base station can compute not only the three-dimensional coordinates of the aircraft, but also the transponder reply time. Preferably estimation filtering calculations, such as Kalman filtering, are used to improve the accuracy. The aircraft's position is compared with a mathematical description of a desired approach path, and the position error is then communicated to the aircraft. Any desired approach path than can be mathematically represented may be used in the system, including paths having curves, steps and segments.

Patent EP-0543932-A4 (EP)
Title: Retinal laser doppler apparatus
Inventor: MILBOCKER MICHAEL T
IPC: A61B3/12
Filed: 1991-07-08
Abstract: A retinal blood flow velocimeter projects an illumination beam through a steering system onto a retinal vessel, and forms a separate tracking image back through the steering system. A fast tracking loop detects motion of the tracking image and moves the steering system to null image motion and keep the illumination beam centered on the vessel. The beam is reflected from the vessel, picked up by detectors at two fixed angles, and processed by spectral analysis. In one preferred embodiment the illumination beam and the steering system follow entirely separate paths through the steering system. Fiber optics translate the collected Doppler light without dispersion while preserving phase relationships, and absolute dimensions are determined from the image tracking electronics. A processor then computes volumetric blood flow which it compares with normative data.

Title: Eurocylinder-type assembly for electronic lock and key system
Inventor: KN SINGH CHHATWAL
IPC: E05B17/22
Filed: 1995-01-20
Abstract: A 'Eurocylinder' configuration for an electronic lock and key system has a plug fitted into a main body housing which is readily mounted into a mortise of standardized dimensions. The plug has a keyway at one end and a deadbolt-engaging cam at the other end. To operate the lock, an electronic key is inserted into the keyway and, when given permission as a result of an opto-electronic communication exchange between a control processor in the key and a control processor in the lock, the key is rotated so as to operate a deadbolt. A spring biased translatable contact serves as a conductive interface between a flex circuit and a contact on the keyblade. The body also includes a solenoid device which is energized by way of the flex circuit. The solenoid device operates a plunger away from the plug to allow rotation of the plug by the key. The body and plug also include a segmented pin arrangement such that when the key and the plug are rotated from a key insertion position, the key cannot be removed. A front end portion of the elongated portion of the housing contains an opto-electronic communication unit which communicates with a complementary opto-electronic communication unit in the key handle.

Title: Enhanced carotenoid accumulation in storage organs of genetically engineered plants
Inventor: HAUPTMANN RANDAL
IPC: A01H5/00
Filed: 1995-10-27
Abstract: A transgenic higher plant, seed containing the transgene, and methods of providing enhanced carotenoid accumulation are disclosed. The transgenic higher plant has a genomic structural gene that encodes a chimeric polypeptide conjugate and over accumulates a colored native carotenoid in a preselected storage organ relative to the accumulation in a non-transgenic plant of the same type. Expression of the chimeric polypeptide is driven by a promoter operatively linked to that structural gene that provides storage organ-enhanced expression. The chimeric polypeptide has an N-terminal plastid transit peptide portion whose C-terminus is linked to the N-terminus of a non-higher plant phytoene synthase enzyme.
