Title: Food registration process for nutrient management apparatus
Inventor: KOGORI HIROAKI
IPC: A23L1/00
Filed: 1989-10-18
Abstract: PURPOSE:To simplify the registration work of a food without necessitating difficult calculation by calculating the content of each nutrient per one meal of a food using a specific operation and registering the calculation results in a food file together with the inputted food name. CONSTITUTION:When a registration key 3 is pressed down after inputting the material names and their amounts, the sum of each nutrient is calculated and the results are displayed on the total column. At the same time, a column 14 for prompting the input of the name of the food is displayed on a window opened on the display. When the name of the food is inputted as 'potato gratin', a column 15 prompting the input of the portion of the material (the number of persons to share the food) is displayed on the window. When '4' is inputted with ten-keys, the sum of each nutrient is divided by 4 (the number of persons) by a calculation part 7. The results are displayed on the window as the content of each nutrient per one meal of the food. The execution key 2 is pressed down and the displayed content of each nutrient in one meal of the food is registered together with the inputted name of the food. When the totalizing key 5 is pushed down. the process is limited to the summation of the amount of each nutrient and the display of the results.

Title: Exhaust gas recirculation device for engine
Inventor: OKANO TAKAYUKI
IPC: F02M25/07
Filed: 1985-12-03
Abstract: PURPOSE:To aim at improvement of the output of an engine by way of suppressing the occurrence of knocking and securing a stable combustion by placing an EGR (Exhaust gas recirculation) passage for the supply of EGR gas in such a manner that it points in the direction of a combustion chamber so as to produce the swirl of EGR gas around the outer periphery of the swirl of fresh air. CONSTITUTION:The No.1 port 6a for supplying fresh air and the No.2 port 6b for supplying EGR gas are directed in the nearly tangential direction of a cylinder. Hereby, fresh air (arrow A) from an air intake passage 11, and EGR gas (arrow B) from an EGR passage 17 produce, in a combustion chamber 5, swirls centering round the shaft center O of the cylinder. In addition, the No.2 port 6b is located outside the No.1 port 6a, and the swirl of EGR gas flows, in layers, outside the swirl of fresh air. And accordingly, since there is in existence almost only fresh air around an ignition plug 23, a stable combustion can be secured, while, since EGR gas is present along the wall surface of the cylinder, the occurrence of knocking can also be suppressed.

Title: Switching circuit
Inventor: ANPO MASAHARU
IPC: H02M1/00
Filed: 1997-10-03
Abstract: PROBLEM TO BE SOLVED: To enable switching at high speed, by forming a plurality of parallel conductive paths from switching elements to a power supply by power supply- side bus bars and looped wires. SOLUTION: A circuit is provided with a looped wire 26P which connects together power supply-side bus bars 18P on the side opposite to a power supply- side wire 24P, and a looped wire 26N which connects together power supply-side bus bars 18N on the side opposite to a power supply-side wire 24N, and the looped wires 26P, 26N are provided with a function of reducing inductance. When a large flyback voltage is apt to be produced in phase U, the current in phase V and phase W is small. Even if creeping occurs, therefore, the operation of switching elements is resistant to the influence of the wraparound. In general, time when a flyback voltage is produced in phase U does not agree with time when switching is performed in phase V or phase W. Therefore, flyback voltages are not superposed. As a result, switching at high speed can be accomplished.

The surface layer becomes the white pig iron, and the solidified layer is formed, and the parting is made when the inner part of the casting is unsolidified, and the cementite constituting the solidified layer is graphitized and the matrix structure is ferritized through the annealing treatment at the heat treatment temperature of 900-950 deg.C immediately after the parting. This constitution allows manufacturing of automobile parts or the like excellent in the toughness (the mechanical strength) and the workability.

Abstract: PURPOSE:To use signal information whose luminance is low in the surroundings of a target which can not conventionally be used, to increase information amount for a detection signal, and to improve an identifying performance by discriminating the target from the feature amounts of a target candidate processed by two threshold values. CONSTITUTION:A picture is binarized by a first threshold value 13a, the target candidate is extracted, and the feature amounts are measured.

Therefore, the picture is binarized by a second threshold value 13b, and the feature amounts are measured in order to remove the convenience. Thus, even when the target causing a image blur exists in the surroundings of the signal detected by the first threshold value 13a, the target can be increased by processing and measuring the feature amounts by the second threshold value 13b, and the actual target can be discriminated from the shot noise. Then, this device is constituted of an A/D conversion circuit 2, video RAM 3, average luminance arithmetic circuit 4, standard deviation arithmetic circuit 5, threshold value arithmetic circuit 6, binary circuit 7, target discriminating circuit 9, and picture measuring part 10.

Abstract: PURPOSE:To make high-precision temperature control and high-speed recording or display operation possible by performing arithmetic operation on the temperature distribution status of a thermal head based on an image signal for recording and controlling the energization time of an applied pulse to each unit heating element according to temperature distribution. CONSTITUTION:The titled unit is provided with a substrate temperature distribution estimating circuit 41 and a substrate temperature measurement circuit 42.

The energization time of an applied pulse to each unit heating element is controlled by an output 75 from the circuit. On the other hand, the substrate temperature measurement circuit 42 is a circuit to detect the temperature of a heat-releasing substrate for a thermal head 11. A substrate temperature signal 47 output from the substrate temperature measurement circuit controls the voltage of an applied pulse from the thermal head 11 to a desired value through an applied voltage control circuit 48. Thus the unit controls an applied voltage as a total heat energy control to the thermal head 11 and controls the time width of an applied pulse as a temperature control for every heating element.
