Title: Adaptive correction of inappropriate shift in automatic transmission based on output torque
Inventor: NARITA YASUSHI
IPC: F16H59/42
Filed: 1990-12-11
Abstract: An adaptive correction of an inappropriate shift operation is such that during a power-off upshift, a variation in output torque of the transmission output shaft is detected (219). A decision is made based on this output torque variation whether or not the power-off 1-2 upshift has been effected in a predetermined appropriate manner, and a timing at which an on-coming friction device to be engaged during the power-off upshift is corrected based on the decision made. Thus, the shift operation during the next occurrence of a power-off upshift of the same type is effected in the appropriate manner. <IMAGE>

Title: Inflatable toy.
Inventor: NAN SIU MAN
IPC: A63H3/06
Filed: 1992-05-14
Abstract: Two portions of an inflatable toy are connected by a joint so as to allow relative rotational movement of the portions. A suitable joint comprises two plastic pans 2, 3 which fit together by a lip and groove construction 5, 7 and may have a hollow flexible tube 8 passing through it to pneumatically connect the two inflatable portions. The toy may be a doll, particularly a life-size inflatable doll for example as sold to adults, with a torso rotationally connected to at least one limb by means of the joint. Such a doll is much more life-like than known inflatable dolls which have fixed limbs. In known dolls, freedom of movement between limbs and torso or between head and torso is dependent upon the flexibility of the inflated material and the extent to which the toy is inflated. <IMAGE>

Title: Driver circuitry for commutated inductive loads
Inventor: AUSTIN CHARLES C
IPC: H02P6/08
Filed: 1992-08-24
Abstract: In driver circuitry e.g. for a DC brushless motor, voltage transients due to changes in load current in a control loop of a pull-down driver circuit including an operational amplifier A1-A3 coupled to a driver transistor M1-M3 can be minimized or deterministically controlled by controlling the rate of change of the input voltage. A variable gain amplifier A4 is inserted into a feedback loop of the pull-down driver circuit for reducing the voltage transients. In an alternative embodiment (Fig 3) the positive input of amplifier A1 is coupled to a current source (I1) and by a capacitor (CF) to the output VOUT of the driver M and the negative input of the amplifier A1 is coupled to the output of an amplifier (A5). In a further embodiment (Fig 5) the output voltage rise and fall times of a pull-up driver circuit can be controlled by means of an accurate clock rate, a capacitance ratio value and an arbitrary voltage supply. Further circuitry is described (Figs 6-8) for controlling the driver circuits to provide dynamic breaking operation. An alternative method for controlling turn off transients associated with inductive loads is described (Fig 9). <IMAGE>

Title: Electric motor control circuit.
Inventor: YAGUCHI OSAMU
IPC: H02H7/085
Filed: 1990-04-30
Abstract: A circuit 70B controls power supply to an electric motor 80 and de-energizes the motor when an overload state, indicated by a detected reduction in motor rotational speed, occurs. Rotational speed is monitored by periodically interrupting the motor power supply and measuring the voltage VM across the motor. A comparator 163 compares this voltage VM with a reference voltage V2 to determine whether an overload condition exists. The comparator 163 controls a sawtooth generator 172, a pulse generator 171 and a transistor 162 in series with motor 80. Alternatively, motor speed may be monitored by a pulse detector (Fig. 15). A particular application for the circuit is driving the motor of an automatic car window, wherein a reduction in motor speed may be due to an object trapped between window and frame during closure. <IMAGE>

Title: Deriving a key signal from a digital video signal
Inventor: SADJADIAN AHMED
IPC: H04N5/275
Filed: 1993-09-10
Abstract: In deriving a key signal for a digital mixer from an input video signal, most values of the key signal are derived by a clip and gain circuit. However, in the special case where the normalised product values for adjacent pixels lie on opposite sides of the upper and lower bounds, the following equations are used to determine the key values (Kl and Kh) for the two adjacent pixels:      Kl = 0.5 (Ub-Lb) * [Ph -0.5 (Ub - Lb)]/(Ph - Pl),      Kh = Kl + 0.5 (Ub - Lb), where Ub and Lb are the upper and lower bound values respectively, and Pl and Ph are respectively the lower and higher product values of said two adjacent pixels.

Title: Image synthesizer and apparatus for playing game using the image synthesizer
Inventor: SASAKI KENJI
IPC: G06T15/04
Filed: 1994-06-10
Abstract: An image synthesizer capable of displaying an image of a three-dimensional object with a small number of polygons in real time with a high resolution. The information about a three-dimensional object is stored in an object data storage (26) as object information for displaying the object using a plurality of shape models of different accuracies. The object information accuracy of shape models is higher as the distance between the viewpoint of a viewpoint coordinate system and the three-dimensional object is shorter. The texture information attached to the polygons of the shapes is stored in a texture information storage (32) as image information having different resolutions according to the shape models and the polygons constituting the shape models. An image forming part (34) synthesizes an image to be displayed by mapping the texture information of accuracies corresponding to the polygons of a three-dimensional object on the polygons of the object generated by a three-dimensional arithmetic part (22) by transformation of perspective projection, and displays it on the display (40). <IMAGE>

IPC: B21B27/10
Filed: 1995-04-26
Abstract: An array of valves and associated nozzle holders 5 is arranged along a header 1, fastened to a manifold plate 2. Each valve has a body 6 with a central valve spool bore 7. A valve spool 11 has a spigot 12 and a closure member 13. A spring 17 is carried on the spigot 12 and acts between the manifold and the closure member 13 to assist the spool towards its normally closed position, in which the closure member 13 sits against the step between the end section 9 and the central section 8 of the bore 7, thereby closing the passage downstream of the port drillings 4. A control air port 20 is in communication via drillings 21 with the end section 10 of the spool bore. Air pressure at the port 20 acts to drive the spool 11 towards the header, opening a passage for the liquid into the central section 8 from whence it is discharged via nozzles 26.

Title: IC op amp. output stage with rail to rail performance improved by current booster
Inventor: FELDT DANIEL C
IPC: H03F1/02
Filed: 1996-07-19
Abstract: An output stage 418 for an operational amplifier (403) powered by a first supply voltage rail 102 and a second supply voltage rail 104 includes a buffer 100 and a current booster 500 for amplifying an input voltage 105 into a low impedance output signal 117 and 520.
