Title: Hot plate carrier
Inventor: SMITH DONALD P
IPC: A23L35/00
Filed: 1990-08-17
Abstract: A carrier (20) for a partially baked dough product (100) having a bottom crust (102) and a moist topping (104) including a vented container (50) for the partially baked dough product and a heater (40) being adapted to initially heat the bottom of the partially baked dough product (100) to a temperature greater than 250°F. to finish backing the crust (102) of the dough product (100), and to maintain the temperature of the crust (102) greater than the temperature of the moist topping (104). The vented container (50) is formed to exhaust moist air from the interior of the container (50) while maintaining the temperature of air adjacent the moist topping (104) on the dough product (100) above the dewpoint of air in the container (50) to prevent condensation of moisture and to draw air from outside the container (50) to expel moisture from adjacent the bottom crust (102).

Patent EP-0424302-A2 (EP)
Inventor: GEYER JOEL ERWIN
IPC: H04L12/433
Filed: 1990-10-09
Abstract: A method for enabling the transmitter to decide the number of variable length frames that can be transmitted within the token holding timer window. The last frame decision algorithm enables the transmitter to set the intermediate frame bit in the ending delimiter to the right state to indicate the status of each frame in the transmitted frame sequence. A look-ahead technique is used to check the remaining transmit time available in the time window, and therefore, no ring bandwidth is wasted on partially trans­mitted aborted frames, effectively optimizing the through­put of the network. Since key variables in the last frame decision algorithm are software programmable, the algo­rithm is independent of ring speed. The algorithm counts transmitted octets instead of measuring transmission time in deciding whether to transmit an additional frame. The algorithm can be applied to either single frame or multi­frame transmit mode and to either normal or early token release. It is applicable to both the IEEE 802.5 local area network standard for token ring networks and the ANSI X3T9.5 standard for FDDI.

Abstract: A tether-guided vehicle and method of controlling same are disclosed. A tether sensor indicates the angle, ϑ, of the tether with respect to the vehicle and the tension, T, on the tether. A contact-sensitive bumper disposed about at least the front periphery of the vehicle indicates the position, P, and force, F, of contact with an obstacle. A drive system moves the vehicle in response to tether angle, ϑ, and tension, T, thereby providing a "servo pull" feature. When the vehicle contacts an obstacle, it stops, backs up, turns and resumes forward motion to circumnavigate the obstacle, thereby providing an "obstacle avoidance" feature. The invention automatically frees a tether-guided vehicle from a jammed condition. It also improves the maneuverability of tether-guided vehicles. The servo pull and obstacle avoidance features make the vehicle suitable in a number of applications, such as for canister vacuums, hospital or factory carts, and the like. The vehicle may be tethered to another robotic vehicle.

Abstract: When an oxide superconducting thin film is formed on a substrate by a vapor phase method such as laser ablation, for example, a plurality of grooves are formed on the substrate by photolithography or beam application in the same direction with an average groove-to-groove pitch of not more than 10 µm, so that the oxide superconducting thin film is formed on a surface provided with such a plurality of grooves. Thus promoted is growth of crystals of the oxide superconducting thin film in parallel with the grooves, whereby respective directions of a-axes and c-axes are regulated to some extent. This improves critical current density of the oxide superconducting thin film.

Abstract: When the receiving conditions deteriorate, RDS broadcast receivers having only one receiving section must use alternative frequencies, the quality assessment of which is no longer current at the time of switch-over. To circumvent the manifold disadvantages of the single-receiver concept, an RDS broadcast receiver having two receiving sections is described which continuously monitors the receiving quality of alternative frequencies with the aid of a background receiver and empirically builds up in a background memory a list of suitable RDS receiving frequencies, ordered in accordance with receiving quality, with and without traffic announcements from the field of action of the mobile receiver. When an RDS broadcast programme without traffic messages is received, traffic announcements on other frequencies of the same transmitting station can be automatically inserted. <IMAGE>

Abstract: The X-ray microscope has a pulsed X-ray source which supplies an intense line radiation such as, for example, a plasma focus source, a reflecting condenser which focuses the radiation of the X-ray source onto the object to be examined, and a X-ray optical system which is constructed as a zone plate and by means of which the object is projected at high resolution onto an X-ray detector. 
<??>By means of this combination, it is still possible in conjunction with a high resolution free from image defects simultaneously to release at the sample point on the imaging side a satisfactorily high level of X-ray energy, thus producing the short exposure times necessary for the examination of living cells.

Abstract: A method and apparatus for coding/decoding an image signal are disclosed. On the coding side, an image signal is divided into an upper signal (y) for coarsely designating a level of the image signal and a lower signal (z) for finally designating the level of the image signal. The upper signal (y) is then coded. A reference signal for coding the lower signal (z) is selected. The lower signal (z) is coded by referring to the selected reference signal. The coded upper (Cy) and the lower signals (Cz) are synthesized, and the synthesized code (C) is output as a code corresponding to the image signal. On the decoding side, the synthesized code (C) is decoded into a code corresponding to the upper signal (Cy') and a code corresponding to the lower signal (Cz'). The code corresponding to the upper signal is decoded into an upper signal (y'). A reference signal for decoding the code corresponding to the lower signal is selected. The code corresponding to the lower signal is decoded into a lower signal (z') by referring to the selected signal. The decoded upper and lower signals are synthesized to obtain the image signal (x').

Abstract: An integrated charge pump circuit with back bias voltage reduction includes one or more diode type voltage multiplier stages, with each stage having a diode-connected NMOS transistor in place of the conventionally-used p-n junction diode. The transistors are formed within a P-type well, which forms the back gate of each transistor within the well, and the transistor threshold voltages are dependent on the potential of the P-type well. Performance of the charge pump circuit using NMOS transistors is enhanced by the use of a bias circuit which generates a bias voltage as a function of the output voltage generated by the charge pump circuit, and applies this bias voltage to the P-type well to minimize the back-body effects of the NMOS transistors. The bias circuit thus permits the construction of an integrated charge pump circuit with significantly lower MOS diode voltage drops than would otherwise be possible.

Abstract: When substrates for holding liquid crystal between them are made of plastic film, the structure becomes thin and lightweight, and conventionally PET or PES was used as the plastic film in manufacture. These materials are, however, low in heat resistance, and the obtained film thickness is small, and the hardness of other constituent elements requiring baking process cannot be improved, and flatness is not obtained. By using transparent thermosetting ally diglycol carbonate resin as the plastic film substrates (3) (15), it is possible to manufacture by using a die made of polished glass, a plastic film of smooth surface and relatively great in film thickness. 
Furthermore, this resin is high in heat resistance, and it can sufficiently withstand the heat treatment of other constituent elements.

Abstract: A fiber optic gyroscope includes a light source, an optical fiber coil, a photodetector and an optical integrated circuit substrate (30) having formed thereon an optical waveguide, whereby light from said light source is split into two for supply to the two ends of the optical fiber coil. A reinforcing plate (50) of a material having a thermal expansion coefficient nearly equal to that of said optical integrated circuit substrate (30) is fixed to the optical integrated circuit substrate. The reinforcing plate is held by flexible holding means (12, 52) for displaceably holding said reinforcing plate on a support structure (10). Thus, even if a thermal stress develops in the reinforcing plate, the reinforcing plate is displaced relative to the support structure to thereby absorb a thermal stress.

Abstract: The susceptibility of austenitic stainless steel is tested by inputting a highly magnified image of the polished and etched steel surface through a microscope (1), a CCD camera and an input device (8) into an image processor (10). The image processor is set up to identify grain boundary locations in the image, take width measurements across the grain boundaries, based on luminance distribution, and calculate average and maximum values for the measured widths. These calculated measured values are compared with experimentally-determined reference values - 1 to 1.5µm for mean width and 2 to 3µm for maximum width - and a susceptibility status determined accordingly. The status can then be output using a display e.g. screen (12) or printer (13).
