Abstract: PURPOSE:To obtain an olefin polymer of a narrow particle size distribution, excellent flow, and a wide MW distribution, by polymerizing an olefin in the presence of a catalyst formed by combining a specified solid catalyst component with an organometallic compound containing a Group I -III metal. CONSTITUTION:A reaction mixture of a silicon compound (e.g., hexamethyldisiloxane) and a compound of a transition metal of a Group IVa, Va, or VIa of the periodic table (e.g., tetraethoxytitanium) is reacted with an organomagnesium compound (e.g., methylmagnesium chloride). The resulting intermediate product is contacted with an organoaluminum halide compound of the formula (wherein R<1> is a C1-C20 organic group, X is a halogen, and 0<c<3) and an oxidizing compound (e.g., oxygen). An olefin is polymerized in the presence of a catalyst formed by combining the obtained solid catalyst component with an organometallic compound containing a metal of a Group I -III of the periodic table (e.g., triethylaluminum).

Title: Drying device
Inventor: WADA KIKUO
IPC: B09B5/00
Filed: 1995-06-16
Abstract: PURPOSE: To promote the occurrence of water vapor generated from an item to be dried by a method wherein a fact that an amount of reduction per time of discharged condensed water becomes more than a predetermined amount is responded against a detected output and an agitating direction of an agitating means is changed over to a direction opposite to a specified direction. CONSTITUTION: As an amount of condensed water in a condensor 203 becomes a predetermined amount, a water level sensor 39 outputs a signal to open a solenoid valve 37. In turn, a control device 101 operates a pump 31 for a specified period of time in response to the signal so as to discharge the condensed water. In this case, as a decreasing degree of the amount of the occurrence of water vapor becomes more than a predetermined amount, it is judged that a drying state of the dried item becomes either a hardened state or a fragile state, a control signal is transmitted to an agitating driving part 69 so as to reverse a rotating direction of its driving shaft. With such an arrangement as above, an agitating direction of the dried item within the drying container 201 is set to be reverse so as to promote the evaporation of moisture contained in the dried item being closely sealed.  Accordingly, it becomes possible to perform an effective heating and drying operation.

Abstract: PURPOSE:To make it startable with relative engine speed and transmission torque withing the limit range of a hydraulic clutch by supplying the hydraulic clutch related to a changeover of forward/first or forward/sixth with hydraulic pressure via a corresponding modulator valve. CONSTITUTION:Forward first to third gear speeds actuate both fifth and seventh hydraulic clutches 4F, 5F by checking their high torque and high speed through control over fifth selector valves B5, B7 and first and second modulator valves M1, M3. In addition, forward/fourth to forward/sixth gear speeds first perform a connection of the fifth hydraulic clutch 4F by the fifth selector valve B5 at a starting point of clutch pedal operation, rotating a shaft 4 at low relative speed equivalent to these forward/first to forward/third gear speeds, then supply of hydraulic pressure to the selector valve B5 in interrupted, separating the clutch 4F, and immediately after that, connection of the six hydraulic clutch 4F is carried out with a sixth selector valve B7 and a third module valve M3 and connection of the seventh hydraulic clutch 5F by the seventh selector valve B7 and the third module valve M3 respectively at the same time. Thus, smooth starting can be done from either speed of these forward/first to forward/sixth gear speeds.

Title: Torque control method of screw fastener
Inventor: OKAJIMA IKUO
IPC: B25B23/14
Filed: 1997-06-09
Abstract: PROBLEM TO BE SOLVED: To mitigate impact force in finishing temporary fastening to rotate a screw until seating it from starting to fasten the screw by gradually reducing output torque of an electric motor and stopping the electric motor at the point of time when seating of a screwed object on a body to be fastened on is detected. SOLUTION: When an operation knob 5 is pressed and moved and an electric source switch 4 is closed, driving of a direct current motor is started, and screwing of a screwed object is started. In a light load state until the screwed object is seated, the screwed object is screwed in a body to be fastened on at high speed. Thereafter, when this screwed object is seated, a fastening load rapidly increases, and it is detected by an electric current detector 16. Accordingly, a timing command by a timing generator 15 is put off, and from this point of time, an electric current value gradually decreases. By this gradual decrease of the electric current, change of torque of the direct current motor becomes moderate, and the motor stops where a shock to a worker becomes small.

Abstract: PURPOSE:To perform a highly precise control of toner density and maintain a stable density of  proper image at all times by correcting the reference frequency which compares with the resonance frequency of toner dinsity of a two-ingredient developing agent in accordance with the  lapse of time, temperature, and humidity after the suspension of the operation of a copier. CONSTITUTION:Toner density is detected with the oscillation frequency of oscillator 2 as f1 by  utilizing the change of reactance as well as resonance frequency due to the mixtute ratio of  carrier and toner resulting from fluidizing of developing agent in the detecting coil 1, air-core  solenoid coil. This toner density is compared in the comparator 3 with the reference frequency f2  from the reference oscillator 4, and if the variation exceeds a certain referecne, the toner is  supplied by driving the supplier 6. The above reference frequency is corrected as follows.  Namely, after the start of copier, suspension time data is sensed, and the reference frequency is  corrected in accordance with the data. After the lapse of the certain time, the correction is  suspended to return to the usual value, and the temperature and humidity data are sensed to  correct the value according to the data. These detection and control are done by using the computer.

Title: Appearance inspection equipment
Inventor: ITO HIDETOSHI
IPC: G01N21/88
Filed: 1997-06-10
Abstract: PROBLEM TO BE SOLVED: To enhance the reliability of GO/NO-GO decision regardless of presence of a streak by replacing the entire data of a line with a constant value depending on the comparison results of variance and a threshold value for each line thereby removing defects present in the line. SOLUTION: A photosensitive drum 1 is illuminated by an illuminator 2 and the image thereof is picked up by means of a line sensor camera 3 and an analog signal therefrom is converted into a digital signal through an A/D converter 5 in an image processor 4. Subsequently, a digital signal processing section 7 preprocesses the image data of the digital signal thus detecting a defect. More specifically, a density histogram is formed for each line in the axial direction of the photosensitive drum and the variance is calculated for each line. The variance is then compared with an experimentally determined threshold value and a decision is made that a streak is present if the variance is lower than the threshold value and then the data of that line is replaced entirely with the average value of data on the lines for which a decision is made that a streak is not present. Since the streak can be removed from the image data, a defect can be detected easily and the reliability of GO/NO-GO decision of a control CPU can be enhanced.
