Title: Thermo-acoustic refrigeration apparatus
Inventor: HAINES D J
IPC: F25B9/14
Filed: 1990-10-19
Abstract: In thermo-acoustic and pulse coolers which operate through the compression and expansion of a working fluid (5) discontinuities in the laminar boundary layer flow of the working fluid over a regenerator plate 2 are caused by pads (3) on the surface of the plates. Alternatively axially spaced ribs are provided, or instead of a series of plates, the regenerator is formed from a coiled strip or nested coaxial tubular plates. The refrigerator comprises a compressor (11), a reservoir (12), and an elongate tube (1). A series of fins (14) remove heat from the tube to ambient. The evaporator portion (7) of the tube contains finely divided metallic material (9), eg wire wool. The downstream part of the tube includes regenerators (15). <IMAGE>

Title: Index control apparatus for tool rest of an NC lathe
Inventor: ISHINO KOJI
IPC: G05B19/23
Filed: 1990-11-13
Abstract: Index control apparatus is provided for a tool rest 40 of an NC lathe for driving the tool rest to a desired indexed position on the basis of an NC machining command. In order to make the swivelling velocity of the tool rest 40 adjustable as desired and to index the tool rest quickly and with a high accuracy, a servo motor 42 is used as the driving source for swivelling the tool rest 40. The servo controller 50 uses both position P and velocity V feedback; position P feedback is also used by index controller 66 to provide a command to servo controller 50, whereby the swivelling angle and the swivelling velocity of the tool rest 40 are optimised. The output torque (current) of the servo motor 42 is limited at the time of clamping/ unclamping the tool rest 40, thereby preventing movement during the clamping/unclamping operation. <IMAGE>

Title: Vehicle headlight
Inventor: YAMADA MASARU
IPC: B60Q1/068
Filed: 1990-12-19
Abstract: A vehicular headlight having an inner lens and a hood which is painted to block light, in which both the lens and the hood are integrally made of a light-transmissible resin so that no opening is formed between the inner lens and the hood. As a result, no light can leak through such an opening, and the adjustment gap between the inner lens and reflector cannot be seen through the opening. Since the inner lens and the hood are constituted by a single component, the number of components of the headlight is reduced to decrease the number of steps of assembly thereof.

IPC: H03M13/13
Filed: 1992-09-07
Abstract: A mutual division circuit of reduced circuit scale and which can be operated at high speed is provided. A switching instruction which selects either a normal- connection or cross-connection is generated at 8 on the basis of an initial value previously set by a connection switching judging block 3 and of a value stored in a register of a block 1. In parallel to this operation, a quotient S from a divider 7 values output from respective preceding stages are stored in registers R of cascaded blocks 2, and one of a normal-connection calculation and a cross-connection calculation (i.e. with operands transposed) is carried out in each block 2 (at 9, 11 or 10, 12) in response to the switching instruction. Further, a value output from the final stage of the blocks 2 is stored in the block 1 and one of the normal-connection calculation and the cross-connection calculation is performed in response to the switching instruction, the quotient being supplied to the blocks 2 to effect an Euclidean mutual division calculation. The circuit is applicable to error correction, the operands being coefficients of syndrome polynomials. <IMAGE>

IPC: G01S17/87
Filed: 1992-09-14
Abstract: The apparatus comprises a camcorder 20 with an IR light source 1 which is directed towards an object 500 to be tracked and ranged. The object 500 carries a further IR light source 110, operating at a different frequency. Reflected light from source 1 and light from source 110 are both received by a single four-element sensor 120 (fig 5). Light from source 1 is received by two elements and is used for ranging purposes, on the basis of time-of-flight. Light from source 110 is received by all four elements; changes in the outputs of individual elements are used to indicate the existence and sense of movement whereupon the camera is moved until the element outputs are equal. The object range is used to automatically focus the camcorder 20. <IMAGE>
