Title: Throttle actuator and intake air quantity controller of internal combustion engine
Inventor: TAJIMA FUMIO
IPC: F02D11/10
Filed: 1992-02-27
Abstract: PURPOSE:To produce a sufficient force simply and accurately without increasing the selection of pole numbers and rotation and requiring a high precision detector by transmitting the rotation of a rotor being rotated by a magnetic flux variation in stator winding to a throttle valve after being decelerated. CONSTITUTION:A throttle valve 4 is supported by a bearing 40 in an intake passage 2 of an internal combustion engine, while in the passage 2 a return spring 29, energizes this valve so as to put back in the closing direction, and a sensor 28 detects this opening. On the other hand, a throttle actuator 5 is equipped with a brushless motor 25 which is composed of a stator 23 consisting of a stator core 39 wound with a stator winding 42 and a magnetic rotor 24 consisting of a permanent magnet. In addition, the brushless motor 25 varies a current to the stator winding 42 by an output signal out of a pole position detector 27. In this case, a rotation of the magnetic rotor 24 is transmitted to the throttle valve 4 after being decelerated by a gear or a speed reducing means.

Title: Method for separating and purifying tellurium
Inventor: ASANO SATOSHI
IPC: C22B3/26
Filed: 1999-02-19
Abstract: PROBLEM TO BE SOLVED: To provide a method for preventing inferior phase separation at co- extraction of impurity elements and back-extraction and recovering high grade metal tellurium by a simplified method using a solvent extraction process, from a tellurium-containing aqueous solution after use for treating copper electrolysis slime or the like. SOLUTION: Dibutyl carbitol is mixed with an aqueous solution which contains tellurium (IV) ions and (5 to 9) mol/l of chloride ions and in which >=3 mol/l of chloride ions, among the chloride ions, are in the form of hydrochloric acid, by which tellurium is selectively extracted. Subsequently, hydrochloric acid in an amount of (1.5 to 4) mol/l is mixed with an organic phase after the tellurium extraction, by which tellurium is back-extracted into aqueous phase. Then, a reducing agent such as sulfur dioxide is added to the aqueous solution after the back-extraction and reduction is effected to 280-300 mV to separate and recover metal tellurium.

Abstract: PURPOSE:To allow the determination of gaseous components even within the period when the output of a gaseous component detector is not stable by previously storing the fluctuation in the zero span characteristic of the gaseous component detector in an unstable state at every temp. at the time of heating start as data with lapse of time. CONSTITUTION:The data on the ambient temp. of the gaseous component detector 3 at the time of heating start and the zero span characteristic corresponding thereto are stored in a memory section 6. On the other hand, the output of a temp. sensor 5 is monitored at the time of the heating start and the fluctuation pattern of the zero span characteristic thereof is selected in an arithmetic section 7. The time elapsed from the heating start is simultaneously counted and the zero span characteristic at the point of the time of the measurement is determined by the fluctuation pattern of the zero span characteristic and the elapsed time and the drift quantity in a reference state is calculated when the measurement of the gas to be detected is made within the period when the output characteristic of the detector 3 is unstable. The actual output value is so corrected as to eliminate this drift quantity and is multiplied by a prescribed oxygen temp. conversion factor. The result thereof is displayed.

Title: Detecting method for misfire
Inventor: MATSUMOTO TAKUYA
IPC: F02P17/12
Filed: 1991-03-07
Abstract: PURPOSE:To improve the calculation accuracy of a misfire in the case of detecting the misfire based on a variation in rotational time width of a crank angle. CONSTITUTION:Each elapsed time ratio of the set first crank angle region of a first cylinder to the set second crank angle region thereof is calculated as leading elapsed time ratio. Each elapsed time ratio of the set first crank angle region of a second cylinder to the set second crank angle region thereof is calculated as trailing elapsed time ratio. A first variation value is obtained from the leading elapsed time ratio and the trailing elapsed time ratio. A second variation value is calculated based on the first variation value. The second variation value is deducted from the first variation value to calculate variation width. The variation width is multiplied by the first variation value to obtain a misfire degree indicating value. Thus, misfire determination is made based on the misfire degree indicating value.

Title: Magnetic head supporting mechanism
Inventor: MAEDA MUNESHIGE
IPC: G11B21/21
Filed: 1988-02-26
Abstract: PURPOSE:To attenuate a vibration of a spring part by providing a fixed end at both sides or one side of the spring part of a load arm in the widthwise direction for suppressing the vibration. CONSTITUTION:The load arm 3 is combined with a rigid plate 1, and both ends of the spring part 4 is combined and also supported by a spring receiver surface 2. Bending vibration, oscillating vibration and torsional vibration take place on the spring part 4 of the load arm 3, and all of these are generated by displacing a spring surface of the spring part in its surface direction, whereas the spring receiver surface 2 acts to suppress this displacement. Consequently, the displacement of the spring part 4 in the surface direction is diminished, and also the widthwise displacement and the right and left surfacewise displacement are ill-balanced. By this method, the vibration of the spring part 4 can be attenuated.

Title: Clock transfer circuit
Inventor: NAGANO HIROSHI
IPC: H03H17/02
Filed: 1989-02-22
Abstract: PURPOSE:To evade erroneous propagation of a signal by providing a coder and a decoder whose bit changes only one simultaneously even when an input signal group changes. CONSTITUTION:Flip-flop circuit groups 4,5 operated synchronously with clocks 1,2 having 2 kinds of independent frequencies are provided. Then a coder 3 whose bit changes only one simultaneously even when an input signal group is provided to a pre-stage and a decoder 6 decoding a signal coded by the coder 3 is provided to a post-stage. Since the input signal group changes by one bit simultaneously, en when a setup time and a hold time of the flip-flop circuit groups 4,5 are not satisfied, an output signal group of the decoder 6 takes either a value before the change in the input signal group of the coder 3 or a value after the change. Thus, the errorneous propagation of the signal is evaded.

Title: Method for detecting failure of ignition sensors
Inventor: NAGASE MASAOMI
IPC: F02P17/00
Filed: 1985-03-04
Abstract: PURPOSE:To eliminate mistaken failure indication and commands for unnecessary exchange of parts by eliminating failure detection due to the smoldering of ignition sensors. CONSTITUTION:It is first decided whether the ignition sensor is in the engine operating area liable to produce smoldering (at engine starting, when the low speed rotation/high load state of the engine is sustained for more than a set time interval) (step 1). When the result of the decision is positive, detection of the ignition sensor failure is inhibited (step 2). It is then decided whether the engine operating area in which the smoldering of the ignition sensor is released (the time interval during which the engine warmup is terminated and the high rotational speed/high load state is continued for more than a set time interval) is elapsed (step 3). If the result is positive, failure detection of the ignition sensor is permitted (step 4) so that the mistaken fail-safe operation based on ignition sensor smoldering or the memory of self diagnosis signals are inhibited.

Filed: 1983-03-16
Abstract: PURPOSE:To control generation of dry gas and perform cracking efficiently, by using a zeolite-containing catalyst having a specified range of rare earth metal exchange ratio in fluid catalytic cracking of heavy oil which contains distillation residues including metal. CONSTITUTION:Zeolite having a rare earth metal exchange ratio of 0.3-0.6 is prepared by replacing an exchangeable cation (e.g. sodium) present in zeolite (e.g. Y type faujasite) with a rare earth metal (e.g. Sc or Y). Heavy oil which contains distillation residuess having a total nickel, vanadium, copper, iron and (or) sodium content of 0.5ppm or higher is subjected to fluid catalytic cracking by use of a catalyst which contains the above zeolite in a matrix component. The method makes it possible to maintain a cracking ratio of 30-90vol%, control generation of dry gas to below 350 SCF/bb1 and produce gasoline with a high octane value.
