Title: Control device for learning of internal combustion engine
Inventor: TOMIZAWA NAOMI
IPC: F02D41/00
Filed: 1987-10-20
Abstract: PURPOSE:To improve learning speed by dividing the deviation of a correction factor from its reference value due to feedback control into factors caused by a fuel injection valve, an airflow meter, etc. based on the degree of satisfaction according to two or more analysis rules and learning same. CONSTITUTION:A control unit 12 operatingly controls the valve opening time of a fuel injection valve 6 based on the detected values of an airflow meter 13, a crank angle sensor 14, a water temperature sensor 15, an O2 sensor 16, etc. When an engine speed and a basic fuel injection quantity are below defined values, the control unit 12 carries out the feedback control of an air-fuel ratio based on the detected value of the O2 sensor 16 and stores the deviation of the correction factor at that time from its reference value. By obtaining the degree of satisfaction for the basic fuel injection quantity according to two or more rules and, based on the degree of satisfaction, the deviation is divided into one caused by the fuel injection valve 6 and one caused by the airflow meter and renewed for each learning zone.

Title: Method for straightening annular body
Inventor: HAMANO HIDEMITSU
IPC: B21D3/14
Filed: 1998-09-17
Abstract: PROBLEM TO BE SOLVED: To easily and exactly judge propriety of a straightening degree by force-fitting a die into the inside of an annular body which is obtained by cutting an Al-made annular extruded shape into a required length with a punch to expand and straighten the annular body and judging a normal/defective condition of straightening based on a punching load value when straightening is executed. SOLUTION: An annular body 1 obtained by extrusion has an inside diameter ϕ1 before straightening. A die 5 which has an outside diameter corresponding to an inside diameter ϕ2 after straightening and whose tip end part peripheral surface 5a is formed into a tapered shape is used in expansion straightening, and is force-fitted into the annular body 1 with a punch. Consequently, the annular body 1 is expanded into the originally necessitated inside diameter i.e., ϕ2 and roundness is high precisely straightened. At this time, a punching load required for expansion straightening is recorded, this value is compared with an allowable range of a preliminarily known punching load, and a normal/ defective condition is judged by defining the annular body 1 within the allowable range as an excellent article and defining the annular body 1 out of the allowable range as a defective article.

Abstract: PURPOSE:To make possible the production of small pieces of ice with good efficiency by prevent an ice layer from being stagnated at the boundary part of a water layer and an oil layer. CONSTITUTION:A water non-soluble liquid O is cooled by the evaporation of refrigerant by a heat exchanger 13 of a cooling means 6 submerged in said water non-soluble liquid O. Accumulated and storaged water W is heat- exchanged with the cooled water non-soluble liquid O to cool water W so as to form a thin ice layer at the boundary part of the water non-soluble liquid O and water W. A fluid E for breaking ice is supplied toward an ice layer from an ice broken means 7, the ice layer is broken, and cracked so as to produce small pieces of ice I. Thereafter, the ice I which floats up in the upper part of the water W by breaking is carried to a heat storage tank 3 by an ice carriage means 4 to store. Further, the water W stored in the heat storage tank 3 by thaw and the like is returned to an ice-making vessel 2 by a water return means 5 again. The ice layer does not stagnate at the boundary part and ice-making efficiency improves.

Title: Hydraulic driving system
Inventor: KANAI TAKASHI
IPC: F15B11/00
Filed: 1989-10-09
Abstract: PURPOSE:To perform stable load sensing control by opening a bleedoff means prior to an unload valve, when the difference between pump discharge pressure and maximum load pressure exceeds a third set value that is smaller than first and second set values. CONSTITUTION:When the discharge amount of a pump 1 is increased more than required due to the delay in response by a pump regulator means 13, and when the difference between a pump discharge pressure and maximum load pressure of actuators 6A, 6B exceeds a third set value that is smaller than values close to a first set value which is not more than a second set value of a bleedoff valve 24, an oil route is opened prior to an unload valve 20. Excess flow of smaller amount compared to an outflow discharge at the time when the pressure difference reaches the second set value, is bled so as to prevent radical increase or decrease in pressure difference. When the pressure difference reaches the second set value which is larger than the first, almost all of the discharge amount of the pump 1 which is at a minimum level of capacity is bled from the unload value 20. Hunting of capacity control is prevented thereby, and stable load sensing control can thus be carried out.

Filed: 1985-11-25
Abstract: PURPOSE:To facilitate the adjustment by providing an insulation film to the tip face of a frequency adjusting machine screw. CONSTITUTION:Even when the frequency adjusting machine screw 7 is turned to change the thickness of an air layer D2, when a material having a large specific dielectric constant such as a ceramic in comparison with air is adopted for an insulator thin plate 11 provided to the tip face of the frequency adjusting screw 7, the rate of change of a static capacitance between a open end 6 of coaxial resonators A, B and the frequency adjusting machine screw 7 with respect to the change in the air layer D2 is very low. Since the change in the said static capacitance with respect to the movement of the frequency adjusting machine screw 7 is very small, the frequency adjustment is facilitated. Further, the assembling accuracy of a screw hole provided to the case 1 and the frequency adjusting machine screw 7 is not good and there is a play in the frequency adjusting screw 7 at the adjustment, then the said static capacitance is not largely fluctuated. Moreover, even when the air layer D2 is very thin, the frequency adjusting machine screw 7 and the inner conductor open end 6 of the coaxial resonators A, B are not directly contacted.
