Title: Oven cooker
Inventor: SHIROKAWA NOBUO
IPC: H05B3/00
Filed: 1986-08-20
Abstract: PURPOSE:To eliminate the overshoot of a temperature at the center of a heating chamber than a preheating temperature, and shorten a time required until the finish of preheating is informed, by heating the heating chamber so that the temperature at the center of the chamber becomes the temperature of a temperature detecting unit added with the correcting value of the temperature. CONSTITUTION:The preheating of an oven is started and Bmin is set in a temperature correcting value B. The Bmin is zero usually, therefore, it clears the temperature correcting value B. Next, the temperature (t) of a temperature detecting unit is measured. Subsequently, it is detected whether overflow is caused in a counter, counting a given time, or not. When the overflow is caused, a value S1 is added to the temperature correcting value B when it is before the finish of the preheating, however, a value S2 is subtracted from the same when it is after the finish of the preheating. Here, there is a condition Bmin<=B<=Bmax. When a temperature T (t+B) is smaller than a preheating temperature C, it is judged that the preheating temperature has not achieved, therefore, heating operation is continued. When T>=C thereafter, it is judged that the preheating temperature has been achieved, therefore, the finish of the preheating is informed and heating operation is stopped further.

Title: Voltage controlled oscillator
Inventor: NAKAMURA TOSHIAKI
IPC: H03L7/08
Filed: 1985-09-03
Abstract: PURPOSE:To increase the isolation between an output terminal of a voltage controlled oscillator and an oscillation circuit section by making the current system of an oscillation circuit equal to that of a buffer circuit and providing a bypass capacitor between the oscillation circuit and the buffer circuit. CONSTITUTION:A power supply is connected in cascode with the oscillation circuit 1 and the buffer circuit 2 to flow the same current to the oscillation circuit 1 and the buffer circuit 2 in the voltage controlled oscillator 5, and the bypass capacitor 3 is provided to a power line 6 between the oscillation circuit 1 and the buffer circuit 2. Since a high frequency current flowing from the power supply line 6 goes to earth via the bypass capacitor 3 entirely, no detour of the high frequency current from the power line 6 to the oscillation circuit 1 exists. Thus, large isolation is attained.

Title: Picture quality improving device
Inventor: FUJIMURA SHIGEO
IPC: G06T5/00
Filed: 1989-07-27
Abstract: PURPOSE:To improve picture quality even when an object is moved by multiply ing a prescribed coefficient to differential data between picture data presently under inputting and picture data inputted to a memory in previous time, adding a multiplied result to the picture data previously inputted, and moving the input/output address of the picture memory while being matched with the mov ing quantity of the object. CONSTITUTION:One frame is stored in a picture memory 2 and for the input of the second frame, the data input/output address of the picture memory 2 is moved by an address moving part 10 based on the object moving quantity to be outputted by a moving quantity detecting part 8. Accordingly, the output of a subtracting part 3 is difference between the picture data previously inputted to the picture memory 2 and the picture data presently under inputting, namely, the differential data of random noise between two frames. Thus, when a multi plier is set to 1/4, for example, in a multiplier setting part 5, 1/4 of the differen tial data of this random noise is added to the picture data stored in the picture memory 2 and by repeating arithmetic input, the level of the random noise is reduced. Thus, even when the object is moved, the picture quality can be improved.

Title: Record cleaner
Inventor: TERAYAMA MASAYA
IPC: G11B3/58
Filed: 1983-10-17
Abstract: PURPOSE:To prevent deformation of the tip of a brush in a preservation time by keeping the tip of the brush a proper gap apart from a placing surface of a record cleaner when the cleaning brush is in the holding attitude. CONSTITUTION:When a switch S is turned off after the cleaning work is terminated, rotation of an intermediate shaft 28 is stopped to extinguish the force which shakes downward an elevating arm 36, and therefore, elevating arms 36 and 40 are returned and shaked upward by springs 37 and 42. As the result, a cleaning brush is switched to the holding attitude from the cleaning attitude in which the lower part of the circumferential face of this brush 11 is projected to the outside of a case from a dust collecting hole 12 of a lower case 2b. Since the cleaning brush 11 is pulled into a dust collecting chamber 5 completely in this holding attitude, the tip of the brush is prevented from being brought into contact with the placing surface of a record cleaner and being deformed at a preservation time.
