Title: Misfire recognition in an engine.
Inventor: MUELLER WERNER
IPC: G01M15/11
Filed: 1992-06-05
Abstract: A system for the recognition of multiple cylinder misfiring, and association of misfires with particular cylinders in the case of recognised multiple misfiring, in a multicylinder internal combustion engine comprises means (10) to ascertain rough-running values for individual cylinders and then, from these, values, to form sum terms. From these, in turn, are formed sums which are compared in comparison means (11) with threshold values from a block (12). If at least one sum exceeds the associated threshold value, this indicates the presence of multiple cylinder misfiring. As soon as multiple cylinder misfiring is recognised, the rough-running threshold values are from a further block (14) lowered, in factor selecting means (13), for association of misfires with particular cylinders. The block (10) receives signals of crankshaft angle and timing cycle. The threshold values from block (12) are themselves dependent on engine speed n and load L. <IMAGE>

Title: Brightness signal/color signal separating filter
Inventor: GAI TOSHIHIRO
IPC: H04N9/78
Filed: 1994-01-24
Abstract: A filter for separating brightness signal and color signal from a composite color signal of HTSC type or PAL type, comprising a horizontal color signal extracting filter 19, a vertical color signal extracting filter 16, a switching circuit 23, and an image correlation judging circuit 1. The image correlation judging circuit 1 makes the switching circuit 23 select one of: the color signal 107 extracted by the horizontal color signal extracting filter; the color signal 105 extracted by the vertical color signal extracting filter; or possibly the color signal 109 extracted by a horizontal/vertical color signal extracting filter 17 depending on the relative correlations of vertical and horizontal brightness and color. The result is that mutual leakage of the brightness signal and the color signal at the area of intensive change into the another's channel can be reduced, thereby avoiding dot jamming and deterioration of image quality. A color signal is output at 24, and a brightness signal, formed by subtracting the color signal from the composite color signal, is output at 26. <IMAGE>

Title: Pressure-connection type semiconductor device and method of fabricating the same
Inventor: NAKASHIMA NOBUHISA
IPC: H01L23/31
Filed: 1994-11-16
Abstract: In order to obtain a pressure-connection type semiconductor device while preventing misregistration of a semiconductor base substrate and a thermal compensator with no penetration of an insulating/holding material and a method suitable for fabricating this device, concentric first and second steps (31c, 31a) are provided on an upper major surface of a first thermal compensator (31) from its outer periphery toward the center. A corner groove (31b) is provided along the overall periphery of an inner comer of the first step (31c), in the form of a ring. Since no insulating/holding material is provided in a contact surface between the semiconductor the substrate and the thermal compensator, the semiconductor base substrate and the thermal compensator are maintained in excellent electrical contact while no local stress is applied to the semiconductor substrate when the same is brought into pressure contact with the thermal compensator. The insulating material is either bonded to the compensator or shaped to simply engage the compensator (Fig. 8, not shown). Details of manufacture of the assembly are also disclosed, involving the use of a forming jig to obtain the requisite shape of the insulating material. <IMAGE>

Title: A radiation field analyzer
Inventor: DEVEREUX ROBERT WILLIAM JOHN
IPC: G01S17/02
Filed: 1996-01-26
Abstract: The analyzer (10) provides means for analyzing the spatial mode spectrum of radiation received from a scene. In a multimode waveguide embodiment, light from a laser (24) is directed towards a scene through an alumina waveguide structure (12). A portion of the laser light is directed towards a mode generator (28) which selectively converts the laser radiation into one of a series of modes. Laser light returning from the scene is mixed with the light from the mode generator to produce interference signals. These signals are measured by a detector (34) and analysed by a programmed computer (36). By sequentially altering the mode generated by the generator (28) and analysing the resulting signals, a spectrum of the modes returning from the scene is obtained. This spectrum can be used to characterize objects within the scene.

Abstract: A plant watering device comprises two co-axial elongate members (10,12) in telescopic relationship, with a first member (10) having a nozzle attachment (16) having a passage (18) therethrough to be connected to a supply of fluid, and a valve 46 provided to adjust the flow of fluid through said passage (18). The two members (10,12) are prevented from rotational displacement one with the other by a bar (30) extending through aligned diametrical apertures (32,34) in both members (10,12). The apertures (32,34) in the first member (10) are of increased dimension along an axis parallel to the axes of the members (10,12) to allow limited axial movement between the members (10,12). A coil spring (36) is provided to bias the first member (10) axially against the bar (30) to open the valve. The first member (10) has support collar (40,42) to which a plant container can be attached. The second member (12) has suspension rings (44) by which the device can be suspended from a support. In use, the compression of spring 36 is determined by the weight of a container suspended from collar 40,42, such that movement of members 10,12, and thus the operation of valve 46, is controled by the wetness or dryness of growing medium in the container.
