Title: Induction heating cooker
Inventor: KOBAYASHI MASAYA
IPC: A47J27/00
Filed: 1994-08-30
Abstract: PURPOSE: To provide an induction heating cooker by which the temperature distribution of a heating vessel is uniformized and which can be accurately controlled by dividing an electromagnetic induction heating coil into an external coil and an internal coil having the prescribed winding ratio, and arranging them at prescribed intervals. CONSTITUTION: An electromagnetic induction heating coil 5 is divided into a flat external coil 5a having an outside diameter larger by a quantity H1 than an outside diameter of a bottom surface of a heating vessel 1 and an internal coil 5b arranged inside of the external coil 5a by separating by H2 =40 to 60mm from the external coil 5a. The number of turns of the external coil 5a is increased by one time to three times more than the number of turns of the internal coil 5b. With this constitution, in the external coil 5a and the internal coil 5b, influence of a magnetic field is mutually reduced, and the uniform temperature distribution is obtained. Heat diffusion to the outside of the heating vessel 1 is compensated, and the heating vessel 1 is also heated from an outer peripheral part, and the uniform temperature distribution of a vessel bottom surface can be obtained.  Therefore, even when it is used in a business cooking appliance whose heating vessel is large, uniform heating becomes possible, and nonuniformity of rice cooking can be eliminated.

Title: Screen distortion correction circuit
Inventor: SUZUKI YOSHITERU
IPC: H04N5/74
Filed: 1990-08-01
Abstract: PURPOSE:To reduce load to a convergence coil and to simplify the circuit by outputting pattern distortion correction currents of reversed polarity to each other to R and B picture horizontal deflection yokes of a projection television receiver respectively from a screen distortion correction transformer and superimposing them so as to correct pattern distortion in the horizontal direction. CONSTITUTION:A drive circuit 15 for screen distortion correction transformer drives a primary coil of a screen distortion correction transformer 16 by a correction waveform outputted from a correction wave generating circuit 10. On the other hand, each one terminal of R, G, B horizontal deflection yokes 7, 8, 9 is connected at one point and they are driven in parallel from a horizontal deflection output circuit 6. Since a G picture horizontal yoke 8 is connected to a neutral point of the screen distortion correction transformer 16, the pattern distortion correction waveform of current IR flowing to the above deflection yokes 7, 9 of reversed polarity to each other is superimposed on a main deflection current. Thus, only the main deflection current flows as a current IG flowing to the G horizontal deflection yoke 8. Thus, the load to the convergence coil is reduced and the circuit is simplified.

Filed: 1998-07-21
Abstract: PROBLEM TO BE SOLVED: To precisely detect a global moving parameter with which multiple picture elements can satisfactorily be predicted and to effectively divide an area even if a prediction error becomes large in a part of a picture. SOLUTION: When a plurality of the candidates of global moving parameters against a moving picture are extracted, prediction pictures corresponding to the respective candidates of the moving vectors are generated (22). A difference (prediction error) between an input picture and the prediction picture is obtained (23). The moving parameters whose prediction errors become minimum are stored at every picture element (24). Areas where the picture elements in which the same parameters are selected continue are connected and the picture elements having the isolated moving parameters are synthesized at a periphery. Thus, the picture is divided into a plurality of areas (25). The moving parameter corresponding to the area where the number of picture elements is maximum among the divided areas is set to be the moving parameter of the whole picture (26).

Title: Image generating method
Inventor: WATABE YASUHIKO
IPC: G06T15/00
Filed: 1993-08-19
Abstract: PURPOSE:To generate an image air aliasing is removed at a high speed by determining the contribution of a pixel which causes the aliasing to luminance by the interpolation of a surface attribute, and determining luminance for plural shapes on the basis of the surface attribute. CONSTITUTION:A pixel striding plural shapes like an aimed pixel 107 is a pixel which causes aliasing. For example, when this aimed pixel 107 is drawn with the surface attribute (vector a) of a shape A102, the shape A102 greatly intrudes into the border on a shape B103. When the surface attribute (vector b) of a shape 103 is used, on the other hand, the shape B103 greatly intrudes into the border on the shape A102. When a background attribute (vector c) is set, the background 106 greatly intrudes into both the shape A102 and shape B103. When the luminance of this aimed pixel 107 is calculated, a liner temporary interpolated value, for example, is used as the surface attribute without calculating the values of the parts of the shape A, shape B, and background respectively.

CONSTITUTION:During cooling, a refrigerant flows to an indoor heat exchanger 5 from an electric type expansion valve 5 through a 4-way valve 2 and an outdoor heat exchanger 3 by means of a compressor 1 to cool the interior of a room through the vaporizing action of a refrigerant. In decision of the delivery temperature of the compressor 1, a delivery temperature is detected by a sensor T1 and is suppressed to a value lower than a limit temperature, and when it exceeds the limit temperature, an electric type expansion valve 4 is opened by a determined amount. A vaporizing temperature is detected by a sensor T2 or T3 of an indoor heat exchanger 5, and when the vaporizing temperature is decreased to a value lower than a given temperature, the electric type expansion valve 4 is opened by a necessary amount. Further, the refrigerant delivery temperature of the compressor 1 is detected by the sensor T1 and a condensation temperature by the sensor T2. A temperature difference obtained by subtracting the condensation temperature from the refrigerant delivery temperature is prevented from becoming to a value lower than a given value, and a refrigerant is prevented from being condensed and gathered in the case of the compressor 1.
