IPC: G05B19/418
Filed: 1989-12-19
Abstract: A system and method for determining which populations in an attribute characterized data set best maximize the significance of variations in a response variable of the data set, the data set being organized into populations characterized by individual attributes or interactions of attributes, the system comprising: means for identifying the population that has the most significant variation in the response variable; means for revising the data set to eliminate the effects of the variation in the response variable associated with the identified population; and means for identifying the population in the revised data set that has the most significant variation in the response variable. The invention also features a system and method for determining which populations in an attribute characterized data set best maximize the significance of variations in a response variable of the data set, the data set organized into populations characterized by individual attributes or interactions of attributes, the system comprising: means for selecting as a test population a universe population comprising all of the data set; means for identifying the subpopulation of said test population that has the most significant variation in the response variable; and means for selecting as a new test population the subpopulation identified by said identifying means if the variation in the response variable of the identified subpopulation is greater than a threshold.

Title: Preparation of substantially polycrystalline silicon carbide fibres from methylpolysilanes
Inventor: DELEEUW DAVID CHARLES
IPC: C04B35/571
Filed: 1990-11-13
Abstract: A process for the preparation of substantially polycrystalline silicon carbide fibers having a small diameter and being thermally stable at high temperatures is carried out by initially forming fibers from a preceramic polymeric precursor comprising methylpolysilane resins. The fibers are then infusibilized to render them nonmelting followed by a pyrolysis step in which the fibers are heated to a temperature in excess of 1600C. in a nonoxidizing atmosphere. The silicon carbide fibers have at least 75% crystallinity and have a density of at least 2.9 g /cm<SP>3</SP>. The polymeric precursor or the fibers contain, or have incorporated therein, at least 0.2% by weight boron. This incorporation of boron may be accomplished either prior to or during formation of the fibers or during at least one of the infusibilizing or pyrolyzing steps of the process.

Title: Cathode ray tube burn compensation
Inventor: SWINSON PETER RICHARD
IPC: H04N3/36
Filed: 1992-01-21
Abstract: Compensation for phosphor burn in a CRT scanner is achieved by offsetting the scan by half a line spacing on alternate scans when the film is stationary in the scanner. To avoid unpleasant effects the offset scan output is suppressed and the previous frame output frozen in the frame store 24. The previous frame is output again from the frame store in place of the offset scan output. Offset scanning is not performed when a control adjustment is made to avoid a juddering effect on the displayed output. <IMAGE>

Title: Electroacoustic transducer
Inventor: FUSHIMI ISAO
IPC: H04R17/00
Filed: 1992-09-24
Abstract: The electroacoustic transducer comprises a diaphragm 101 including an elastic plate 103 and an added mass 105 secured to a center portion of the elastic plate 103. The added mass 105 has a contact portion which is shaped to provide a portion to allow for deformation of the elastic plate 103 within an imaginary circle defined by connecting an outer surface portion of the contact portion. Thus, the contact portion can provide a deformable elastic-plate portion within that circle. Therefore, it is possible to accomplish such a structure obtained as if by connecting different springs having different spring characteristics, located outside and inside the circle. This structure can suppress and stabilize a variation in resonance frequency (fo) caused by a change in the vibration amplitude of the diaphragm 101. The reproducibility of an output to an input is thus improved. Various forms of the added mass are disclosed (Figs 9 to 27). The invention may be applied to either electromagnetic or piezoelectric transducers (Figs 28. 29). <IMAGE>

The key members (2, 3) are retained in the opening (10) by a retainer (4). Because each key member may act as two direction control buttons, the UP and DOWN buttons may be provided by one key member and function independently of the LEFT and RIGHT buttons provided by the other key member. <IMAGE>

Title: Loudspeaking telephones
Inventor: HASHIMOTO KAZUO
IPC: H04M1/60
Filed: 1993-09-29
Abstract: Although the voice of a called party will be amplified when telephone 1 associated with the device is placed on-hook first during a telephone conversation, amplification will not occur if the called party places his or her phone on-hook first during a telephone conversation or if the user places telephone 1 on-hook before the called party picks up the telephone. The structure, which is shown in Figure 1, is such that during a telephone conversation between telephone 1 and telephone 12, when telephone 1 is placed on-hook first, the on-hook status is detected by means of the photocouplers PC-1 or PC-2, and the voice of the opposite party at telephone 12 is amplified by means of contacts y1-1 and y1-2, which are in the make position, line transformer 2, amplifier 3 and speaker 4. Further, when the opposite party's telephone 12 is placed on-hook first, the voice of the opposite party will not be amplified because a reversal of polarity and a brief disconnection on telephone line 13 are detected by means of photocouplers PC-1 and PC-2. <IMAGE>
