Title: Fault containment system for multiprocessor with shared memory
Inventor: FRANK STEVEN J
IPC: G06F12/16
Filed: 1992-09-15
Abstract: Abstract A multiprocessor system has a plurality of processing cells, each including a processor and memory, interconnected via a network. The memories respond to requests by the processors for accessing data and, absent fault, transmitting it in response packets to at least to the requesting processors.  A fault containment element responds to at least certain faults during access or transmission of a datum for including within the respective response packet a fault signal that prevents the requestor from accessing the datum.  If a fault is detected in a datum not previously detected as faulty, a marking element can include a "marked fault" signal in the response packet.  Whereas, it can include an "unmarked fault" signal when it detects a fault associated with a requested datum, but not specifically isolated to that datum.  When a request is made for a datum which had previously been detected as faulty, the marking element can include in the response packet a "descriptor fault" signal.  This facilitates identification of a particular source of an error and prevents that error from propagating to other processing cells.

Title: Direct imaging process for forming resist pattern on a surface, and use thereof in fabricating printed boards
Inventor: GRUNWALD JOHN
IPC: B41M5/36
Filed: 1993-03-09
Abstract: ABSTRACT OF THE DISCLOSURE        A process  is  described for the direct production of  an  imaged  pattern  of  resist on a substrate surface (such   as  a  pattern  of  etch-resistant  organic  resin material  on the  surface  of a copper-clad dielectric in connection  with a printed circuit board (PCB) fabrication process),  which  process  utilizes  thermo-resists rather than   photoresists,   i.e.,  compositions  which  undergo thermally-induced,  rather  than  photo-induced,  chemical transformations.    A film  of  thermo-resist composition applied  to  the substrate surface is scanned by a focused heat  source  (e.g.,  a  thermal  laser emitting in the IR region)  in  a predetermined pattern, without a phototool, to   bring   about  localized  thermally-induced  chemical transformations  of  the composition which either directly produce  the  resist  pattern  or  produce  in  the film a developable latent image of the pattern.

Patent CA-2093252-A1 (CA)
Inventor: ARNOLD KEITH P
IPC: F41G7/22
Filed: 1993-04-02
Abstract: A low noise frequency synthesizer 10 that uses uses frequency dividers 13, 15, at least one of which(divider 15) is incrementable and decrementable in half integer steps, and analog gain compensation in a phase/frequency detector 17 to achieve lower noise, lower spurious levels and faster switching speed than traditional methods of frequency synthesis. The key features of the present invention are its half integer dividers 13, 15 and the ability to adjust the phase detector gain to compensate the loop for varying divide numbers. The synthesizer 10 comprises two dividers 13, 15 that provide two reference frequency signals that are a function of an input signal and an output signal of the synthesizer 10.  A voltage controlled oscillator (VCO) 18 provides the output signal (fO) of the frequency synthesizer 10.  A phase/frequency detector 17 compares the reference frequency signals and provides a phase error output signal that drives the VCO 18. A digital controller, comprising a PROM 11 and a digital to analog converter 12, adjusts the gain of the phase detector 17 to compensate for varying divide numbers, and selects the divide numbers. The synthesizer 10 has lower phase noise, lower spurious levels and faster frequency channel switching. To generate a frequency step of a given size, the divide number is half the step size. With a divide number of half the step size, the noise contribution from the divider is reduced by that much. The phase margin is improved with a corresponding reduction in loop peaking in the noise spectrum. A missile radar system employing the present synthesizer is also disclosed.

Abstract: A  transfermix  includes  a  component  having  an internal operating surface provided with a helical thread and  an  interior  component  having  an  external  operating surface  provided  with  a  helical  thread  of  a  different direction  but  coaxial  with  the  helical  thread  on  the component having the internal operating surface, the helical threads facing one another and defining a passage for a medium to be mixed.   The envelope defined by the crown of the interior thread is within the envelope defined by the crown of the exterior thread up to and including coincidence of  the  envelopes,  and  the  cross-sectional  areas  of  the grooves  of  the  facing  threads  vary  in  opposite  senses between  a maximum and  a minimum value  for  each of  the threads along substantially the same length of the passage. The helical thread of which the groove cross-section  is being reduced comprises at least two starts of which one over a part of the axial length is reduced in groove cross-section at a lesser rate than the other is so reduced and over a different part of the axial length the first start is reduced in its groove cross-sectional area at a faster rate than the other is so reduced.  In this way in operation the medium is caused to move in the passage, portions thereof are transferred between the grooves of the facing helical threads  as  giver  and  taker,  with  some  portions  in  the initially more slowly reducing start of the giver-groove being transferred  into the  taker-groove  later  than  some portions in the other start of the giver-groove,  whereby over the axial length of transfermix geometry a measure of longitudinal  mixing  is  effected  in  addition  to  the transverse mixing.

Title: Automobile safety air belt with air bag
Inventor: OHM HANG-SUP
IPC: B60R21/18
Filed: 1993-11-03
Abstract: ABSTRACT OF THE DISCLOSURE      An automobile safety air belt with an air bag.   This safety belt is provided with air passages in its sections corresponding to the abdomen, the side,  the breast and the shoulder of a passenger, and with an air bag in its section intending to be fastened diagonally about the upper part of the passenger body from the side to the shoulder through the breast.   In the case of a traffic accident, the safety air belt is charged in a moment with the pressurized air in its air passage as well  as  in  its  air bag by an  additional operating device in order to be expanded, thus to cause the expanded air bag to be precisely rapidly interposed between the passenger and the car body  irrespective of collision velocity  of  the  automobile  and  to  reliably  protect  the passenger from collision with the car body.  The safety air belt of this invention forms an air belt section due to the air passages charged with the pressurized air in the case of automobile  collision,  thus  to  sufficiently  absorb  the mechanical shock which is otherwise applied to the abdomen, the breast and the shoulder of the passenger, and to prevent a serious  injury  of the passenger  such as an  intestinal rupture or fracture of a bone.
