Inventor: TOGANOU HIROTAKA
IPC: C07C27/00
Filed: 1979-08-15
Abstract: PURPOSE: To prepare the titled compound, in high selectivity, using a relatively small amount of water, by supplying a reaction mixture comprising ethylene oxide and water at a specific flow rate to a tubular reactor having a heating zone at the middle thereof, and after the conversion rate has reached to a specific value, heating and reacting the reaction mixture.  
     CONSTITUTION: A reaction mixture composed of water and ethylene oxide (molar ratio, 10/1W25/1) is supplied continuously to one end of a tubular reactor having a heating zone which supplies heat from outside system to the reaction system. The flow rate of the reaction mixture is controlled to give the Raynold's number of ≥7×10 4  at the reactor. The reaction mixture is made to react in the pre-reaction zone at ≤180°C, pref. ≤160°C until the conversion of ethylene oxide reaches 80%, pref. 90W95%. After the reaction in the pre-reaction zone, the mixture is further reacted by heating in the heating zone until the conversion reaches 100%.  
     EFFECT: The reaction time for the last stage of the reaction can be shortened, and the total volume of the reactor can be reduced.

Title: Preparation of metal fiber reinforced plastic material
Inventor: KUSANAGI HIROAKI
IPC: B29B11/00
Filed: 1983-06-09
Abstract: PURPOSE:To form a metal fiber reinforced composite plastic material containing a long metal fiber and excellent in mechanical strength, by continuously supplying the long metal fiber from the intermediate part of a heating cylinder. CONSTITUTION:A plastic stock material supplied from a plastic stock material supply hopper 16 is melted while compressed and transferred by the rotation of a screw 12. The long metal fiber 23 supplied from a metal fiber supply hopper 17 is sent into the molten plastic stock material and kneaded with the plastic stock material while shortly sheared by strong shearing force caused by the rotation of the screw 12 and the resulting compound is extruded from a lead end extrusion orifice 25. On the other hand, a noxious volatile component is sucked and removed from a volatile component removing port 15 by a vacuum pump 18. As mentioned above, by continuously supplying the long metal fiber continued in a longitudinal direction, it can be stably and quantitatively supplied without generating bridging in the hopper and the supply amount thereof can be also easily controlled. In addition, by mixing the metal fiber in a long state, a large amount of a metal fiber reinforced plastic material having excellent strength can be formed.

Title: Developing device and process cartridge
Inventor: SHINTANI SUSUMU
IPC: G03G15/08
Filed: 1998-03-30
Abstract: PROBLEM TO BE SOLVED: To absorb the difference of deforming amount between a developing frame and a supporting plate caused by temperature change and to obtain stable press-contact force by pressuring an elastic member pressing a developing blade and fixing it on the developing frame. SOLUTION: In the case of joining the supporting plate 101, an elastic blade 102 and a presser plate 103 are joined, a wave washer 109 having spring property is put between the plate 103 and a small screw 106 so as to join them. At such a time, the washer 109 is fixed after constant squeezing amount is given to the washer 109 because the screw 106 is a stepped small screw. Thus, the plate 101, the blade 102 and the plate 103 are pressed by constant force more weakly than ordinary joining. By such constitution, even when the temperature of a developing cartridge is changed and the developing member supporting frame 63A is largely deformed, slippage occurs between the frame 63A and the plate 101 on the screw 106 side, as a result, the constant press-contact force of the developing blade is always obtained without forming a gap between the plates 101 and 103.

CONSTITUTION:When a switch corresponding to an outflow port on the side desired to be used is pressed by means of a setter 26, the feed of hot air is started at a preset temperature and opening. Current regulation of a flow rate is effected such that a motor 31 is run, a valve disc 35 is forcibly opened through helical movement of a shaft 37, and an opening detected by a potentiometer 66 is set to a set value. When, during the feed of hot water, a route is switched to other outlet side, the other switch is pressed by means of the setter 26. The motor 31 is reversed, a flow rate regulating valve 27 is closed, the motor 31 is further run in the same direction, and a switching valve disc 54 is switched in a reverse direction. When the motor 31 is further in the same direction, the flow rate regulating valve opens a flow passage. This constitution simplifies and compacts constitution and reduces probability of a leakage.

Abstract: PROBLEM TO BE SOLVED: To improve time resolution of an image substantially without deteriorating the image by use of FSE method by providing a means for using the data of a peripheral area in common every time the data of a central area is all obtained to reconfigurate the respective images from the data of K space filling in the whole area. SOLUTION: At the time of collecting data, an image reconfigurating device two-dimensional Fourier-transforms K space filled up with data to conduct the image reconfiguration processing. That is, concerning the peripheral areas Kb, Kc of the K space, the data first collected by a first to sixth TR is used in common, whereby every time the data of the central area Ka is collected, the data of the whole K space is completed, so that at every time, two-dimensional Fourier transform is conducted to obtain an image. Thus, a new image can be obtained only by the time for collecting data needed for filling in the central area Ka, and TR for three times is an image interval time IT so that the time resolution of an image is three times as large as that in an ordinary case.

Title: Device for controlling number of idling revolutions of internal combustion engine
Inventor: FUSHITSUGU YUTAKA
IPC: F02M69/32
Filed: 1997-04-22
Abstract: PROBLEM TO BE SOLVED: To improve response to a required flow and to prevent an increase in flow as much as possible by providing an armature whose outer periphery is slidably screwed in a rotor and whose inner periphery is slidably screwed on the shaft of a throttle valve. SOLUTION: The flow of air is controlled by a valve element 8 moved back and forth in the axial direction by the electromagnetic force of a coil controlled by a control unit. That is, in a state in which the armature 5 is not in contact with the stopper 4 of a shaft 3, an armature 5 is rotated integrally with a rotor 2 and the shaft 3 is moved slightly to the rotational angle of the rotor 2 because of the small pitch of threads cut on the inner periphery of the armature 5 in which the shaft 3 is slidably screwed. On the other hand, in a state in which the armature 5 is in contact with the stopper 4 of a shaft 3 and is rotated with the shaft 3, the shaft 3 is moved greatly to the rotational angle of the rotor 2 because of the large pitch of threads cut on the outer surface of the periphery of the armature 5 on which the rotor 2 is slidably screwed.  Therefore, the amount of movement of the shaft 3 is determined by the pitch of threads cut on the inner surface of the hole of the armature 5.

Abstract: PURPOSE:To enable stable manufacturing by mitigating tensile stress drastically, by a method wherein an inner layer skin molded on a winding mold is shifted on a processing mold whose diameter is slightly larger than that of the winding mold and a core material is stuck to the external circumference. CONSTITUTION:An inner layer skin 1 molded on a winding mold A through a filament winding (FW) method is shifted onto a processing mold B whose diameter is slightly larger than that of the winding mold by removing the inner layer skin 1 from the winding mold and a form of the outside of the same is shaped through machining. Then a core material molded beforehand is stuck to the external circumferential surface of the skin 1 and a form of the external circumferential surface of a core 2 is shaped through machining. As for a laminate whose dimensions of the outside diameter of the core 2 has been shaped, winding, curing and molding of an outer layer skin 3 based on the FW method are performed on the external circumferential surface of the core 2 by either shifting the same to the winding mold A by removing the same once from the processing mold B or leaving the same on the processing mold B as it is and the external circumferential surface of the skin 3 is machine. With this construction, mitigation effect on tensile stress can be obtained. A crack is not generated on a foam.
