Inventor: HARRIES DAVID ANTHONY
IPC: B60T8/26
Filed: 1989-02-23
Abstract: A vehicle antilock braking system has a master cylinder (20) which upon brake application will provide a source of high pressure fluid. The master cylinder (20) serves at least one braking circuit, said braking circuit including a first brake actuator (11; 13) associated with one wheel of the vehicle and a second brake actuator (17; 15) associated with another wheel of the vehicle. Control means (24, 26, 28; 25, 27, 29) includes means (26, 28; 27, 29) for sensing a change of velocity of said one wheel and valve means (24, 25) for reducing the pressure of fluid delivered to the brake actuators (11, 17; 13, 15) when wheel deceleration increases above a predetermined limit. The valve means (24; 25) is arranged to reduce the pressure to said first brake actuator (11; 13) at a slower rate than the pressure to said second brake actuator (17; 15).

Title: Multi-pulse voice encoder
Inventor: SATOH YAYOI
IPC: G10L19/10
Filed: 1989-03-28
Abstract: In a pulse searching arrangement (65) of a multi-pulse voice encoder comprising a linear prediction residual signal producing arrangement (61), a pitch period is predicted in a cross-correlation domain in each subframe of a frame of an input voice signal. For this purpose, a local signal producing circuit comprises a first cross-correlator (66) for producing a first cross-correlation signal related to a linear prediction residual signal. A buffer memory (32) produces an output cross-correlation signal from subframe to subframe. Supplied with a sum signal and controlled by a pitch period signal representative of pitch periods of the input voice signal, a pitch synthesizing filter (71) produces a synthesized signal, which is added to provide the sum signal to a signal representative of excitation pulses. Responsive to the synthesized signal, a second cross-correlator (67) produces a second cross-correlation signal, which is subtracted from the output cross-correlation signal to provide the local signal. Supplied with an autocorrelation signal, a pulse searcher (44) searches the excitation pulses in the local signal.

Title: Device and method for measuring shape and dimensions of workpiece in sawing machine, and device for automatically adjusting saw blade guide
Inventor: MORIYA KIKUO
IPC: B23D55/08
Filed: 1989-05-12
Abstract: A bandsaw machine 1 has means for determining the shape and dimensions of a workpiece W to be cut. Such means may comprise a contact angle detector 31, a width detector 33 and a vertical surface detector 35. The angle of contact of the saw 23 with the workpiece, the width D of the workpiece and the presence or absence of a vertical side are fed into a calculation device 39 which compares these values with those obtained from a series of equations relating to theoretical dimensions of different workpieces and selects the best fit to obtain an estimate of the dimensions of the workpiece W. Alternatively the dimensions of the workpiece W may be directly measured by a photographic device (49, Fig 6) and image processing device (51). This information may be used to control the movement of a movable saw blade guide 29, during cutting, so that the distance between the saw blade guides 27, 29 corresponds to the width of the cut for all portions of the workpiece W being cut. The bandsaw machine illustrated has a pivoted saw blade housing 5. In an alternative machine, the saw blade housing is horizontal and guided for vertical movement on a vertical guide post. In a further alternative, the machine is a vertical bandsaw machine. Both saw blade guides (27, 29) may be movable and provided with saw blade proximity sensors (75, 77, Fig 10). <IMAGE>

Title: Mass spectrometer capable of multiple simultaneous detection
Inventor: ISHIHARA MORIO
IPC: H01J49/26
Filed: 1989-07-03
Abstract: In a mass spectrometer capable of multiple simultaneous detection, the operation mode can be switched between a mode in which a wide mass range is obtained and another mode in which high resolution is obtained. The spectrometer includes a mass analyzer having at least a magnetic sector 3 and a two-dimensional ion detector 4 placed along a focal plane of the analyzer for simultaneously detecting ions focused and dispersed by the analyzer according to mass-to-charge ratio. A lens means 5,6 having variable magnitude is disposed in the ion path between the magnetic sector 3 and the detector 4. In one embodiment position-adjusting means 7 places the detector 4 along the focal plane which differs, depending upon the magnitude of the lens means 5. Alternatively, one of a plurality of differently positioned detectors 4 can be selected. The lens means may consist of two quadrupole lenses 5,6 arranged in series which assume one of predetermined sets of magnitudes. Depending on the value of this magnitude, the angle of the detector 4 is then adjusted to position it along the focal plane. Alternatively, detector adjusting mechanism can be dispensed with by using a sextupole lens in conjunction with the quadrupole lenses and varying the magnitude to bring the focal plane into coincidence with the detector 4.

Title: Nucleic acid sequences for the production of transgenic animals prone to thrombi, dilated cardiomyopathy or the like
Inventor: SEARLE PETER FRANCIS
IPC: C12Q1/6897
Filed: 1991-08-01
Abstract: A nucleic acid consists of DNA comprising a gene sequence coding for an Epstein-Barr virus nuclear antigen leader protein or homologue or derivative preferably fused to an upstream segment containing a mouse metallothionein-I gene sequence providing promoter and control sequences and fused to a downstream segment containing a human growth hormone gene sequence (hGH). Transgenic animals such as mice produced by incorporating this DNA into the genome thereof have a substantially increased probability of spontaneously developing blood clotting or thrombi in their circulatory system, especially in the left atrium of the heart, and/or symptoms of dilated cardiomyopathy or similar heart dysfunction. Such animals can be useful for screening and identifying or testing drugs or other substances for antithrombotic or thrombolytic activity or for cardiotherapeutic activity for use in human medicine.

Title: Method of forming an insulating region in a semiconductor device
Inventor: JIN TAE-JE
IPC: H01L21/76
Filed: 1991-09-10
Abstract: In a process for forming an element insulating region 44 in a semiconductor device, a buffer oxide layer 30 is formed on a semiconductor substrate 28 of a first conductive type, and polysilicon and nitride layers 32, 36 are sequentially formed on the buffer oxide layer 30. Then, part of the nitride layer 36 formed on a predetermined element insulating region is selectively removed, and a polysilicon layer 42, of which the thickness is similar to that of the nitride layer 36, is formed between the inner side walls of the remaining nitride layer portions 36. Thereafter, the polysilicon layer 42 is oxidized, and then the remaining nitride layer 36 and polysilicon layer 32 are removed, to thereby form an insulating oxide layer 44 without affecting the substrate. Consequently, there is provided an insulating region in which bird's beak phenomenon and stress on the substrate 28 are reduced. <IMAGE>

Title: Glass toughening quench system
Inventor: LAND MICHAEL BRYAN
IPC: C03B27/04
Filed: 1991-12-28
Abstract: The air quench system described is a system to provide large volumes of high velocity air directed onto the surfaces of sheet glass to rapidly cool and thus toughen the glass. This is achieved by the use of specially designed compressed air ejectors fitted in manifolds. Compressed air escapes at very high velocity into the throat of the nozzles, and draws into the nozzle cap a much larger volume of atmospheric air. This provides the high volume of quenching air directed onto the glass surfaces. <IMAGE>
