Title: Cooker
Inventor: FUNAKURA SHUICHI
IPC: A47J43/046
Filed: 1987-11-25
Abstract: PURPOSE: To provide a cooking device which is efficient and capable of whipping in a short time by providing a rotating body which is rotated by a driving mechanism at the inner bottom of a container, shaping the rotating body into a disk, and arranging an annular rib on the inside of the circumferential end of the upper surface of the disk. CONSTITUTION: A disk-shaped rotating body 4 is fixed to a shaft 3, and an annular rib 5 is provided on the inside of the peripheral end of the upper surface of the rotating body 4. When the rotating body 4 is rotated, materials to be cooked are drawn from the center of the rotating body 4, thrown horizontally from the periphery of the rotating body 4 and pushed upward to be primarily mixed with air, and further pushed to the inner wall of the annular rib 5 on the upper surface of the rotating body 4 to be secondarily mixed. A part of the material is thrown upward by the inner wall of the rib 5 and instantly again drawn from the center of the rotating body 4. Then, a part of the secondarily mixed materials is thrown from the rib 5 outward, and the materials are tertiarily mixed with air. Furthermore, the materials are efficiently whipped in a short time as the speed of stirring circulation of the materials increases with the increase in contact resistance between the rotating body 4 and the materials.

Title: Controller of internal combustion engine
Inventor: IKEDA MUNETOYO
IPC: F02D41/14
Filed: 1998-10-19
Abstract: PROBLEM TO BE SOLVED: To restrain racing of engine rotation by a torque increase and an increase in an NOx exhaust quantity while restraining a misfire by setting a lower limit value of the target equivalent ratio so that the equivalent ratio just after switching to homogeneous combustion from stratified combustion becomes an optimal value. SOLUTION: When operating an engine, first of all the basic target equivalent ratio is determined by searching a map on the basis of a basic engine operating state of an engine speed and target torque by the basic target equivalent ratio operation part A to perform phase delay correction B on the basic target equivalent ratio. Next the phase-corrected target equivalent ratio is compared with a threshold value by the combustion state switching judging part C to judge actual switching from stratified combustion to homogeneous combustion.  When detecting a transitional state in the homogeneous combustion just after switching to the homogeneous combustion from the stratified combustion by the detecting part D, a range capable of adopting the phase delay-corrected target equivalent ratio is regulated by upper/lower limit values of the target equivalent ratio set according to the transitional state by the equivalent ratio limiter part E.

Filed: 1987-11-24
Abstract: PURPOSE:To obtain a plane delay characteristics by adding a phase shifting circuit having fixed amplitude characteristics in all frequency ranges and phase characteristics relating to frequency to an active filter.

Abstract: PURPOSE:To enable a high thermal efficiency to be provided by a method wherein a catalyst body having a platinum catalyst carried on a honey-comb structure and a flame port main body for causing mixture gas of fuel gas and combustion air to be guided to a lower portion of the catalyst are arranged. CONSTITUTION:As fuel gas is injected from a nozzle 2, the fuel gas sucks air from a gap 3 to form mixture gas, passes through communication holes 13 and 13 to concave portions 11 and 11, further passes through a space between partition walls 1a and 1a of a catalyst 1 and then is injected to the upper surface of the catalyst 1. When the mixture gas is ignited, an overall temperature of the catalyst 1 is increased as the gas is burnt, and as the gas temperature is increased to more than about 150 deg.C, the platinum catalyst carried on the catalyst 1 may accelerate a contact reaction between the passing gas and the air, resulting in that the entire catalyst 1 is red heated and then a large amount of heat is released onto the upper surface of the catalyst. Thus, it becomes possible to make an efficient heating of the item 4 to be heated if the item is placed near the upper surface of the catalyst 1.
