Title: Induction heating cooking utensil
Inventor: SHIMIZU KOICHI
IPC: H05B6/12
Filed: 1987-09-30
Abstract: PURPOSE:To attain proper cooking temperature quickly by adding the product of specified time and the rate of change of the sensed temperature from a temperature sensing part, thereupon calculating the predicted temperature comparing it with the set temperature, determining the heating output, and then emitting a control signal. CONSTITUTION:A microcomputer is incorporated in a control circuit 7 and fed with the setting temp. set on a temperature setting part 6 and the sensed temperature sensed by a temperature sensing part 5, followed by conversion, calculation, and determination of the heating output, and then a command is given to a frequency converting circuit 8, and a pan 1 and oil 2 are heated by induction heating with a heating coil 4. That is, when objects to be cooked are less and the rate of temperature rise is great, the sensed temperature is considerably low, but the predicted temperature is calculated high because the rate of temperature rise is great, and thus the heating output is controlled, and the objects are prevented from getting excessive high temperature. When objects to be cooked are much and the rate of temperature rise is small, the set temperature is attained quickly. Thus proper heating output is obtained automatically at all times.

Title: Signal transmission system combining adaptive filter and phase displacement modulation
Inventor: NAKAMURA HIDEO
IPC: H04B3/54
Filed: 1988-10-03
Abstract: PURPOSE:To remove a noise component and to speed up a signal transmission by automatically adjusting the variable parameter of an adaptive filter and Fourier- demodulating the modulated wave where the phase displacement modulation is executed, so that the difference between the output of the adaptive filter and the norm input can be zero. CONSTITUTION:A phase displacement modulating signal is inputted through an A/D converter 1 and through an adaptive filter part 2 to synthesizers 5 and 6. On the other hand, a norm input signal generates norm inputs d(k), and -d(k) having mutually the 180 deg. different phase through an A/D converter 3 and inputs them to the synthesizers 5 and 6. At this time, the parameter of the filter 2 is automatically adjusted so that the difference between the output of the filter 2 and the norm input can be zero. Thus, for outputs r1(k) and r2(k) of the synthesizers 5 and 6, one side becomes a time series including a noise component only and other side becomes the time series in which the signal and the noise component are synthesized, and by relative-demodulating by a Fourier-demodulating part 7 and executing the prescribed operation, the signal removing the noise is obtained. Consequently, the signal is resistant to the noise and the signal transmission can be speeded up.

Filed: 1997-09-12
Abstract: PROBLEM TO BE SOLVED: To increase the thermal margin of a reactor core by constituting the rector core with a first fuel assembly and a second fuel assembly with less number of fuel rods and then loading a fuel for the specific cycle of the first fuel assembly at a specific position. SOLUTION: A reactor core consists of 324 conventional fuel assemblies 11 and 76 fuel assemblies A12 with a high degree of combustion. The conventional fuel assemblies 11 are constituted by bundling 60 fuel rods and a water rod and covering them with a channel box. The assemblies A12 with a high degree of combustion are constituted of 66 standard fuel rods, 8 partial length fuel rods, and the water rod. In the reactor core, the second cycle fuel of the conventional fuel assemblies 11 is loaded to outer-periphery regions up to the fourth layer from an outer periphery and a control cell adjacent region 22. When a new fuel where the fuel assemblies A12 with a high degree of combustion are not combusted is loaded to the reactor core that is constituted of the conventional fuel assemblies 11, output is maximized at the second-cycle fuel of the conventional fuel assemblies 11.  Therefore, with this sort of loading, a margin for the operation control value of the maximum linear power density can be secured.

Title: Tire inspection device and method
Inventor: NAKAYAMA HIROYUKI
IPC: G01M17/02
Filed: 1999-09-02
Abstract: PROBLEM TO BE SOLVED: To establish an automated inspection method by a physical method instead of a sensory analysis. SOLUTION: The tire inspection device consists of a scanning mechanism for appropriately positioning a temperature-measuring device for a tire 7 to be inspected, a temperature change imparting device 2 for generating a temperature change in the tire 7 to be inspected, and an optical device for optical detecting a heat ray being emitted from the surface of the tire 7 to be inspected. The temperature change does not strictly report the absolute value of physical properties but is a physical phenomenon for fully reflecting the difference in physical properties. The defect in layer structure as in the tire faithfully appears as the relative change in a surface temperature. The presence or absence of an internal defect can be verified clearly according to the surface temperature distribution by the temperature change in the surface.  The presence or absence, location, and spread may be determined as a relative difference, and no strict measurement of temperature is required.

Title: Mold for molding optical disc board
Inventor: SATO HIROMI
IPC: B29C45/26
Filed: 1988-09-30
Abstract: PURPOSE:To prevent abnormal transfer from occurring at the molding of an optical disk board and to reduce mold making cost by a method wherein a stamper is positioned and held at its inner peripheral part, the thermal expansion thereof is small, and, at the same time, the stamper is bonded to a mold member. CONSTITUTION:A stamper 6 and the neighborhood of the plane part 2a of a mold member 2 thermally expand by the heat transferred from molten resin filled in a cavity 4. However, since no thermal expansion develops on the positioning part 7b side of a retaining member 7, which positions the stamper 6, no strain develops in the stamper 6 near its central hole 6b. Further, since the stamper 6 is apart from the intermediate inner peripheral surface 8a of an engaging member 8 by a gap S, neither warpage nor strain develops in the stamper 6 due to a force applied to the outer peripheral part of the stamper. With the lowering of the temperature of the resin in the cavity 4, shrinkage generates in the resin in the cavity 4 and simultaneously the stamper 6 and the neighborhood of the plane part 2a of the mold member 2. At this time, since the shrinkage factor of the resin in the cavity 4 (or of an optical disc board) is larger than that of the stamper 6, the board in the cavity 4 tends to shrink relative to the stamper 6. However, since the stamper 6 is bonded by adhesive A to the plane part 2a of the mold member 2, no levitation and separation of the stamper from the plane part 2a occurs.
