Patent EP-0371511-A2 (EP)
Inventor: AKIZUKI KUNIO
IPC: F21S8/10
Filed: 1989-11-30
Abstract: The inner reflecting surface of the concave mirror (10) of the projector-type headlamp is composed of a central spherical area (5) and a composite ellipsoidal surface of revolution (E) formed by parts of a plurality of different ellipsoidal surfaces of revo­lution, smoothly joined to each other for junction with the central spherical area (S), having a common focus at the center (O) of the spherical area and other foci (F), respectively, at positions spaced ahead of a predetermined distance from the common focus. The lamp bulb (12) is so disposed so as to have the center thereof located near the common focus (O), and the convex lens (14) is so dis­posed as to have the focus thereof located near the common focus (O). The ellipsoidal surfaces of revolution (E) are so shaped geometrically as to reflect in directions toward their respec­tive other foci (F) the rays emitted from the lamp bulb (12) and inci­dent upon the ellipsoidal surfaces of revolution (E), and the convex lens (14) is so designed as to have the focus thereof located near the common focus (O) of the ellipsoidal surfaces of revolution (E) at which the lamp bulb (12) is located. Thereby, it is possible to decrease the total length of the optical system, design compact the entire structure of the projector-type headlamp and in­crease the effective solid angle of the rays emitted from the lamp bulb, thereby permitting to utilize the rays from the lamp bulb to full extent for definition of a predetermined luminous intensity distribution pattern.

Abstract: In a method an apparatus for decoding data recorded on magnetic storage medium such as a "swipe card" to yield decoded data values, a magnetoresistive sensor is used to read the data as a pulse stream from the medium and to measure the widths of the received pulses. The data is preferably stored in the medium by the technique of two-frequency phase coherent recording (F2F). By comparing the widths of pulses to be decoded with the widths of previously read pulses to which data values have already been allocated circuitry for derivin a clock signal from a self-clocking recorded signal can be dispensed with. Pulse widths may be measured by monitoring the output of counters (20) incremented by a fast clock for the duration of each pulse, and the pulse widths are compared by comparing counter outputs stored in a memory (28) using a microprocessor (26). To allow data to be read from the recording medium at a wide range of pulse repetition rates without excessively increasing counter capacity, thecounters (20) may be clocked at a variable rate dependent on the repetition rate of the received pulses.

Abstract: A pressure integrated apparatus and process for the measured injection of sample into a capillary (Q) for electrophoresis is disclosed. Preferably the cap­illary (Q) is mounted in a serpentine path to a cartridge body (C) having a bottom. The capillary (Q), previously filled with electrolyte depends a distance below the bottom of the cartridge (C) and has its periphery sealed to the car­tridge. Typically, the cartridge is registered at the depending capillary to a vial of sample. The vial of sample is moved into substantial gas tight relation with the cartridge so that the depending capillary is below the surface of liquid within the sample vial. The vial is then communicated to a source of substan­tially constant fluid pressure in the order of 1 lb./inch². At the same time, a pressure gauge (60) monitors the pressure of the vial and outputs a signal to integra­tion apparatus (I) such as a microprocessor. By time integra­tion of the area under a pressure curve, precise monitor­ing of the amount of fluid introduced into a capillary occurs. Assuming a total capillary capacity of several microliters, injections of sample in the order of 5 nanoliters with an accuracy of plus or minus 2% is possible.

Title: Nonlinear resonant switch and converter
Inventor: ERICKSON ROBERT W JR DR
IPC: H02M3/10
Filed: 1989-08-09
Abstract: A nonlinear resonant switch (10) for power conversion devices and a converter using the switch are described. The switch optimizes converter efficiency by switching only when current is zero and by limiting the peak current to a value near that provided by conventional PWM converters. A nonlinear reactor (28-32) having a winding (28) in series with the switch and a tank circuit (26,36) is biased to saturation at low currents but is driven into an unsaturated condition by high currents so that a resultant high series inductance mitigates further current increase. Several converter topologies incorporating this improvement are shown.

Abstract: The invention relates to a transportable dismountable booth and a method for manufacturing such a booth which is made up of several connectable segments (1, 2, 3).

Regarding the booth itself, which comprises several wall segments (1, 2, 3) and if necessary at least one ceiling segment (5) and one floor segment (4), which can be joined together to form a substantially closed booth, it is proposed that at least some of the wall segments (1, 2, 3) should comprise a wall section (1', 2', 3') whose base outline is at least externally essentially straight and at least one second wall section (1a, 1b, 2a, 2b, 3a, 3b) which is angled away from it at an angle of at most 90 DEG and is firmly fixed to the first wall section.
