Title: Surface processing method for oil well steel pipe joint
Inventor: ATSUMI TAKUYA
IPC: C23C22/78
Filed: 1995-04-04
Abstract: PURPOSE: To improve seizure resistance in a screw part and in a seal part between metal materials by heating the screw part and the metal seal part in an atmosphere with a specific oxygen concentration so as to generate an oxide scale and forming a chromate coating film on the oxide scale when surface treatment is carried out on an oil well steel pipe joint. CONSTITUTION: When surface treatment is carried out on an oil well steel pipe joint 1 provided with a screw part 3 and a metal seal part 4, heating is carried out in the screw part 3 and the metal seal part 4 at a heating temperature of 400-700 deg.C in an atmosphere with oxygen concentration of 3-18% for 5 minutes or more for generating an oxide scale, on which a chromate coating film with thickness of 0.3μm or more is formed. The chromate treatment is carried out, for example, by performing electrolysis for a fixed time while using a joint 1 side as a negative electrode and using a platinum as a positive electrode in an acid liquid consisting of chromic anhydride and sulfuric acid. In this way, the oil well steel pipe joint 1 is coated by means of the oxide scale treatment and the chromate treatment, so that seizure resistance can be greatly improved.

Abstract: PURPOSE:To avoid deterioration of the cache hit factor and also to improve both operability and availability of a system, by invalidating a cache part on the corresponding side in case a cache part has a high error frequency and utilizing the other cache part for both instructions and data. CONSTITUTION:The parity error detecting circuits 114 and 153 detect a errors respectively. In other words, a counter 154 counts those detected errors when signal lines 175 and 177 are set at logical '1'. Then the count value of the counter 154 is added with 1 for each detection of an error. The initial value of the counter 154 is equal to '0'. A comparator 156 checks whether the value of the counter 154 is coincident with the contents of a register 155 set previously. If the coincidence is secured through the comparator 156, an interruption signal line 182 is equal to logical '1' and an interruption is given to a microprocessor 1. That is, a data cache part 5 can be used for both instructions and data by setting both an instruction access mode F/F and a data access mode F/F to the part 5.

Abstract: PURPOSE: To conserve fuel for automobile by a method wherein an electric motor for driving is attached to a transmission and the electric motor is driven by an excessed electrical power generated while driving.  
     CONSTITUTION: Automobile has generated an electrical power by a generator thereof while driving and has charged it into a battery. However, when a voltage has attained to a rated voltage, the generator has been rendered inoperative and further generation of the electricity has not been effected any more. Therefore, it is preferable to prepare a battery having a capacity powerful enough to be charged further by utilizing said generator while an electric motor 1 attached to a transmission for driving is driven by the electricity thus obtained in order to drive the car. In this case, the car is driven by an engine as in the case of the conventional manner at starting because a large torque is necessary therefor, while the car is driven with the electricity by switching from the engine drive into the electric motor 1 drive when the car is brought into a constant speed driving condition.

Abstract: PURPOSE:To prevent the improper learning of air-fuel ratio and always control the ratio to the optimum in a method of closed-loop control of the learning of the air-fuel ratio, by controlling the learning so that an air-fuel ratio feedback compensation coefficient approaches a prescribed value at each of plural skips. CONSTITUTION:A basic fuel injection period TP determined in terms of the load (intake pipe pressure PM or sucked air quantity Q/NE per rotation of an engine) upon the engine and its rotational frequency is compensated by an air- fuel ratio feedback compensation coefficient FAF which is for the proportional integration of the injection period on the basis of the output signal of an O2 sensor for detecting the residual oxygen concentration of exhaust gas, so that the air-fuel ratio of a mixture is controlled to be equal to an aimed value. It is judged whether a count CSKIP has exceeded a prescribed value C1 (3, for instance) and is larger than another prescribed value C2 (C2>C1). If the count CSKIP is larger than the value C2, the count is equalized to the value C1 and the average value FAFAV of the compensation coefficient FAF is thereafter calculated.
