IPC: F02D41/04
Filed: 1985-10-25
Abstract: PURPOSE:To perform air-fuel ratio control in an extensive control range in a stable manner, by reducing a rate in a fundamental supply of fuel at a specified driving range, while increasing a rate of compensation fuel, and increasing the control allotment of a control valve. CONSTITUTION:Fuel delivered to a suction passage 7 from a nozzle 6 is mixed with air and fed to an engine 12. Each electric signal out of sensors 15-19 detecting a driving state of the engine 12 is inputted into a control unit 9, and the proper driving signal calculated on the basis of these information data is fed to a control valve 10. The control unit 9 reduces a rate of a fundamental supply in a fuel flow rate to be demanded at a driving zone where a suction air quantity of the engine is little, while it increases a rate of compensation fuel, and control allotment of the control valve 10 is increased. Thus, air-fuel ratio control is performable in an extensive control range so stable enough.

Title: Picture encoding method and device
Inventor: KONDO TETSUJIRO
IPC: H04N19/423
Filed: 1993-08-31
Abstract: PURPOSE:To improve a compressing efficiency, and to prevent the deterioration of a picture quality by discriminating a block activity based on the prescribed block of hierarchical data, and controlling a block division processing based on the compared result of a threshold value set for each hierarchy with the block activity at the time of hierarchy-encoding picture data. CONSTITUTION:A picture encoding device 40 sets the threshold value of each hierarchy in order to attain encoding under consideration of a human visual sense characteristic. The block division processing is selected to the picture data of the higher-rank hierarchy which affects a wide area, and the block division processing is not selected to the picture data of the lower-rank hierarchy which affects only a narrow area. The memory (not indicated) of a hierarchy encoding encoder part 40A delays the data so that an encode processing can not be executed until an optimal control value is decided by a generated information amount control part 40B. On the other hand, the generated information amount control part 40B inputs input picture data, and decides the threshold value suitable for data to be processed.

Title: Foil-wound transformer
Inventor: TOGAWA YASUNOBU
IPC: H01F27/28
Filed: 1984-11-15
Abstract: PURPOSE:To facilitate a winding work to be performed on the winding of a cooling panel as well as to enhance cooling effect by a method wherein a wide-widthed cooling panel having the width same as that of a metal sheet and a narrow-widthed cooling panel, to be partially arranged on the upper and the lower end parts only of the winding, are cojointly used as the cooling panel to be wound in a winding. CONSTITUTION:On the upper and the lower end parts in axial direction of a winding, as a narrow-widthed cooling panel 21 is arranged on the area where an eddy current is concentrated, the upper and the lower parts of the winding can be cooled in an excellently efficient manner. Also, as a wind-in metal plate 22 is provided on the intermediate part of the narrow-widthed cooling panel 21 arranged on the upper and the lower parts of the winding, no gap is generated and the winding can be tightly wound. Moreover, the heat generated on the center part of the winding in axial direction is cooled by the wide-widthed cooling panel 6, which is same as that heretofore in use, wound in the winding. Accordingly, the manufacturing cost of the cooling panel to be wound on a foil-like winding can be cut down and the manufacturing process can also be simplified by cojointly using the wide-widthed cooling panel 6 of the same width as that which is heretofore in use and the narrow-widthed cooling panel 21.

Title: Manufacture of semiconductor element
Inventor: AKIYAMA KOICHI
IPC: H01L21/28
Filed: 1990-09-10
Abstract: PURPOSE:To reduce the turn-on and turn-off losses of a semiconductor element by respectively vacuum-depositing aluminum on the alloy surface sides of a silicon substrate and tungsten plate in advance and forming an alloy by heat-treating the aluminum by using eutectic aluminum-silicon foil as a brazing material. CONSTITUTION:A vacuum-deposited aluminum film 14a is formed on the alloy surface side of a silicon substrate 12 by vacuum-depositing aluminum and, at the same time, another vacuum-deposited aluminum film 14b is formed on the alloy surface side of a tungsten plate 8 by vacuum-depositing aluminum. Then, in order to assure the ohmic contact between the anode surface of the substrate 12 and vacuum-deposited aluminum films 14a and 14b, the films 14a and 14b are heat-treated at 400-500 deg.C. Then the substrate 12 and tungsten plate 8 respectively having vacuum-deposited aluminum films are heat-treated at a relatively low temperature of 580-620 deg.C in a nitrogen gas atmosphere by using eutectic aluminum-silicon foil 7 as a brazing material so as to stick the substrate 12 and plate 8 to each other as an alloy. Since the alloy is formed at a lower temperature than the conventional example, the depth of the silicon 13 eroded by the aluminum becomes shallower and turn on voltage and turn on and off losses are also reduced.

Title: Refrigerator
Inventor: MURATA YASUKIYO
IPC: F25D21/06
Filed: 1992-09-08
Abstract: PURPOSE:To optimize the period or automatic defrosting operation for a cooler so as to conform to the condition of practical use and prevent wasteful consumption of electric power by providing a controlling means for controlling the regular period of starting the defrosting operation to be prolonged in the case where the operation rate of a compressor calculated by a calculation means is not higher than a preset upper limit value. CONSTITUTION:After defrosting operation for a cooler 6 is finished, a calculation means 16 calculates an operation rate of a compressor 10 for freezing cycle drive. In the case where the operation rate or the compressor calculated by the calculation means 16 is not more than a preset upper limit value i.e., in the case where a rate at which the compressor 10 is operated is relatively low, so that the amount of frost produced on the cooler 6 is small, a controlling means 13 allows the regular period of starting the defrosting operation for the cooler 6 to be prolonged. As a result, when a state is such that the operation rate of the compressor is relatively low and the amount of frost to be produced on the cooler 6 is small, there is no possibility that the defrosting operation for the cooler is carried out in frequency more than necessity, whereby wasteful power consumption can be prevented.
