摘要:
A method of evaluating endurance of a vehicle wheel by computer simulation of a dynamic radial fatigue test. The modeling of the system is simplified by modeling the tire portion made of a nonlinear material by linear elements, and modeling each of the air pressure, the press-contact effect of the tire bead portion and the load applied through the contact between the tire and the drum is modeled as the direct load. With such a modeling, the stress applied to the vehicle wheel can be calculated by the linear analysis instead of the nonlinear analysis, and as a results thereof, the memory capacity and the calculation time are reduced.

A process for purifying gold-bearing iodine lixiviant characterized by bringing the gold-bearing lixiviant into contact with a strongly acidic cation-exchange resin to selectively adsorb heavy metals while allowing gold and iodine to pass therethrough. The process is particularly useful for purifying gold-bearing iodine lixiviant prior to recovering the gold by electrolysis.
摘要:
A method and an apparatus for elevator group control, capable of improving the transport efficiency without severely lowering the overall quality of service, even when the traffic demand to a particular floor sharply increased in a particular period of time. In the apparatus, the elevator cars of the elevator system are controlled according to the hall call allocation control based on the transport efficiency of the elevator system, such that in a case the response elevator car having an ultimate destination floor is additionally allocated to another floor which is located in an opposite direction from an ultimate destination of the response elevator car, the responds elevator car is controlled to reverse a direction of motion to serve said another floor and then to reverse the direction of motion again to move to the ultimate destination floor.
摘要:
A process for eluting gold-iodine complex from an ion-exchange resin, characterized by adding sulfuric acid and sodium nitrite to the gold-iodine complex adsorbed on the resin, and adding sodium sulfite as an eluant. The process is particularly useful for eluting gold-iodine complex adsorbed on strongly basic anion-exchange resin, such as washings resulting from the washing of leach residue which has been passed through the resin.

Control apparatus (and a control method) for a vehicle, the vehicle including: an internal combustion engine (EG); a brake booster (21) in which an intake negative pressure of the internal combustion engine is used; and a brake master cylinder (22) connected to an onboard hydraulic pressure actuator (33), the control apparatus comprising: pressure detecting means (27) for detecting a fluid pressure of the brake master cylinder; driving state detecting means (133) for detecting the driving state of the internal combustion engine; and control means (11) for retarding an ignition timing with a throttle valve (114) of the internal combustion engine opened in a case where the driving state detected by the driving state detecting means is in the idle driving state during a cold state of the internal combustion engine and for driving the fluid pressure actuator to assist the brake master cylinder in a case where the fluid pressure detected by the pressure detecting means is equal to or lower than a predetermined value during the idling state of the engine and during the cold state of the engine.
摘要:
An apparatus for performing group control on elevators, wherein a plurality of elevators are operated for a plurality of floors, a predetermined evaluation calculation is performed for each of the plurality of elevators upon generation of a hall call, an optimum elevator car is selected on the basis of an evaluation calculation result, and the selected elevator car is assigned to the hall call, thereby responding to the hall call, the apparatus, comprises a unit controller, arranged in units of cars of the elevators, for controlling unit control of each car and inputting/outputting information associated with its own car, a plurality of group controllers for performing the evaluation calculation for determining hall-call assignment in units of cars on the basis of the information associated with its own car and for performing group management of each elevator car on the basis of an evaluation calculation result, and a communicating circuit for causing the plurality of group controllers to communicate with each other through a first data field and causes the unit control means and the group controllers to communicate with each other through a second data field independent of the first data field.
摘要:
A first compressor (1a) which supercharges intake air is provided in the intake passage (6, 20, 21) of an internal combustion engine (12). The first compressor (1a) is driven by the exhaust gas energy of the engine (12). A second compressor (2a) driven by an electric motor (2b), and a bypass valve (3) which bypasses the second compressor (2a), are provided in the intake passage (7, 20, 21) between the first compressor (1a) and the engine (12). The bypass valve (3) shifts from the open state to the closed state according to the operation of the second compressor (2a). At this time, the bypass valve (3) starts closing at some time after startup of the second compressor (2a) so that the intake air amount of the engine (12) is not deficient.
摘要:
An elevator control system which provide a high transportation efficiency and also provides for equalization of service quality between floors when a large number of passengers located at different floors desire transportation to a common particular floor. Passengers waiting at a lower level floor will first be picked up prior to the elevator moving to the upper level floors so that the passengers at the lower levels will also be able to get on the elevator when there is a large number of passengers who wish to go to a particular floor during a particular time of the day.
