Title: Hydraulic circuit for hydraulic shovel
Inventor: HIRATA TOUICHI
IPC: E02F9/22
Filed: 1979-07-13
Abstract: PURPOSE: To achieve an effective utilization of the energy of a motor, by branching the output line of the third pump and communicating the thusformed branch line with a change-over valve of an arm through a throttle valve.  
     CONSTITUTION: An output line C of the third pump 3 is branched into lines (h) and (i). The line (h) is led to a change-over valve 31 for a turning motor while the line (i) is communicated with a change-over valve 22 for an arm through a throttle valve E. When the turning motor and arm are simultanenously operated, a flow of pressure oil required for the actuation and acceleration of the turning motor is supplied to the turning motor through the line (h) and change-over valve 31 and remaining pressure oil is fed to an arm hydraulic cylinder via the throttle vavle E and change-over valve 22 of the arm. Thus, the turning motor is driven with priority by the pressure oil from the third pump 3 and, at the same time, the actuation speed of the hydraulic cylinder for the arm can be accelerated, resulting in an effective utilization of the energy of the motor.

Title: Electromagnetic clutch controller for vehicle
Inventor: NAITOU YASUO
IPC: B60W10/04
Filed: 1980-06-26
Abstract: PURPOSE: To avoid shocks from abrupt actions of the engine brake applied at a speed faster than the set value by realizing a buffer coupling by gradually increasing the electromagnetic clutch excitation when the car speed reaches the predetermined speed while the acceleration pedal is kept in the free state.  
     CONSTITUTION: During car run on a down slope, if the acceleration pedal is not pressed and a switch 9 is at the OFF position, when the speed is below the set value and a switch 10 is at the OFF position, a transistor 2 is turned off and a coil 1 of the clutch is not excited. When the speed increases and reaches the set value, the switch 10 is turned on and a signal of H level is inputted a switching circuit 18. At the same time, a mode sensor 22 turns on the transistor of an instantaneous switching control circuit 21 and lets a capacitor 214 discharge. Therefore, the circuit 18 selects output of an oscillator 17 for a predetermined length of time and the output drives the transistor 2, gradually increasing the excitation current of the coil 1. Thus, the engine brake is applied gradually without generating shocks.

Title: Gas pressure adjusting device of air forced feed type gas burner
Inventor: INAGAKI HIDEO
IPC: F23N1/00
Filed: 1986-04-17
Abstract: PURPOSE:To extend the characteristics of a governor for adjusting supply gas pressure from the case of a burner dealing with large calorific capacity to that with small calorific capacity and at the same time make it possible to adjust the gas pressure in a smooth manner functionally by a method wherein the air pressure developed by a supply air fan is led to the diaphragm chamber of this governor by making the fan side opening of a conduit face an air flow rate adjusting part, which controls the amount of air supplied to a combustion chamber. CONSTITUTION:When the maximum input to a main gas burner is intended, the opening of a damper 17 is set to its maximum and consequently the amount of forced-fed air becomes maximum and at the same time the air pressure fed through a conduit 2 to the diaphragm chamber D of a governor G for adjusting supply gas pressure also becomes maximum, resulting in making a gas passage area between a valve seat 15 and a governor valve V larger. When the minimum input to the main gas burner is intended, the opening of the damper is set to its minimum and consequently the air pressure fed to the diaphragm chamber D becomes nearly zero and a low pressure developed by almost only the pressure by a governor spring 16 is exerted, resulting in making the gas passage area between the valve seat 15 and the governor valve V smaller. Thus, secondary pressure P2 is automatically controlled constant with respect to the change of supply pressure P1 within the range of the amount of gas supplied.

Filed: 1996-04-11
Abstract: PROBLEM TO BE SOLVED: To enable direct production of a hydrogen peroxide soln. having medium or low concn. by using city water for a person who requires a hydrogen peroxide soln. SOLUTION: Electrolytic reduction is carried out by introducing city water and air into an electrolytic cell 1 which uses a gaseous diffusion electrode as a cathode to produce hydrogen peroxide and to obtain a hydrogen peroxide soln. The produced hydrogen peroxide soln. is circulated between the electrolytic cell 1 and a reservoir 7, and electrolytic reduction is further continued to produce hydrogen peroxide to increase its concn. Thus, a hydrogen peroxide soln. of a desired concn. suitable for the purpose can be produced. This method is safe because handling of hydrogen peroxide of high concn. is not required, and the cost for equipments can be saved.

Title: Convection and steaming oven and food cooking method
Inventor: BEN MIRAA
IPC: A21B3/04
Filed: 1987-04-14
Abstract: A cooking oven for cooking foodstuffs with either steam or forced convection hot air. In the steam mode, steam is continuously generated in the oven cavity (18). Alternatively, in the convection mode, the amount of moisture supplied to the cavity is controlled. A fan (26) circulates the air or steam in the oven cavity. The steam is generated by means of a slinger cup (66) to which water is supplied and from which water will flow in a thin film over an edge portion of the cup to be slung outwardly and to be atomized by centrifugal force. The atomized water is then caused to flow, by means of the fan, over a heater (36) to be heated thereby whereby the atomized water flashes into water vapor or steam. The oven is operated at atmospheric pressure. Food juices and condensed steam or water vapor which collect in the bottom of the oven will be drained therefrom by means of a drain which is open to the atmosphere. The oven temperature is selectively variable by means of an automatic control (84).

Abstract: PURPOSE:To ensure a quick control for injection of chemicals and to obtain the raw water of a prescribed degree of concentration despite a long distance between an injector and the actual injection point of chemicals, by securing an automatic and consecutive control for the injection factor of chemicals to the raw water. CONSTITUTION:The output of a flow rate meter 11 is fed to the 1st arithmetic part 13 and multiplied by a fixed ratio signal which is decided from the chlorine injection factor and the chlorine water concentration to the measured raw water flow rate. This multiplied output is supplied to the 1st control meter 14. The meter 14 sets the output given from the part 13 as the target value and obtains a control degree proportional to the deviation between the target value and the pressure water measured by a pressure water flow rate meter 15 or the chlorine water flow rate obtained by adding chlorine to said pressure water. Then a flow rate control valve 16 is controlled. Furthermore a control degree with which a valve 18b is operated is obtained from the output of the 2nd arithmetic part 17 having a function to multiply the flow rate of the pressure water or the chlorine water by a certain ratio signal and the output of a chlorine gas flow rate meter 18a of an injector 18. In such a way, the raw water of a prescribed degree of chlorine water concentration is obtained despite a change of the flow rate of the pressure water or the chlorine water.
