IPC: B29C48/92
Filed: 1981-07-31
Abstract: PURPOSE:To obtain a high-quality foamed article having expansion degree of >=3 and suable for the practical purpose, by using a foaming agent decomposable at low temperature in combination with a foaming agent decomposable at high temperature, and compounding the powder of the low-temperature decomposing foaming agent directly to polyolefin pellets. CONSTITUTION:In the preparation of a polyolefin foamed article using a chemical foaming agent, (A) a low-temperature decomposable foaming agent having a decomposition temperature of 130-150 deg.C (e.g. p, p'-oxybisbenzenesulfonyl hydrazide) is used in combination with (B) a high-temperature decomposing foaming agent having a decomposition temperature of 180-200 deg.C (e.g. azodicarbonamide), the powder of the foaming agent (A) is compounded directly to polyolefin pellets, and the composition is foamed by using a conventional extruder. The amount of the agent (A) is >=1wt% of the composition, and that of the agent (B) is 0.05-1pt.wt. per 1pt.wt. of the agent (A). Addition of 0.1-1.0pt.wt. of polyolefin powder to 1pt.wt. of the foaming agents in the direct compounding with the polyolefin pellets, facilitates the uniform dispersion of the agents.

Title: Data phase compensating circuit
Inventor: HIDA MINORU
IPC: G11B20/14
Filed: 1989-05-12
Abstract: PURPOSE:To obtain a data phase compensating circuit which has the high phase compensating accuracy together with its scale to be miniaturized and receives no influence of the temperature characteristic, the delay value, etc., by performing no control of an original channel clock if a reference bit has a defect or is not recorded yet. CONSTITUTION:A read-out reproduction signal is sampled by an A/D converter 2 with use of a channel clock, and a reference bit part is detected out of the sampled reproduction signal. A phase detecting circuit 3 detects a phase error of the channel clock to the reference bit part. Then the phase of an original channel clock is controlled based on the detected phase error for compensation of the phases of the channel clock and the reproduction signal. Meanwhile the original channel clock is not controlled if a reference bit has a defect or is not recorded yet. Thus it is possible to obtain a data phase compensating circuit which has the high phase compensating accuracy together with its scale to be miniaturized and receives no influence of the temperature characteristic, the delay value, etc.

Title: Epi-motor
Inventor: MITA YASUYUKI
IPC: H02K7/08
Filed: 1978-09-29
Abstract: PURPOSE: To eliminate wear and the unevenness of revolution due to swing-rotation motion, by positioning the centroid of a body of revolution containing load in a single bearing all the time by projecting the bearing to the bowllike yoke side of a rotor from an end surface of a stator.  
     CONSTITUTION: A pivot 8 of an epi-rotor 7 is supported by means of a single bearing 6 in a cylindrical portion 5 fixing a stator 2 in a revolution-free shape. The bearing is formed in a shape that an end surface 61 at the impeller 11 side as the load of the bearing 6 is projected to the load side only by dimensions l from an end surface 21 at the load side of the stator core 2. Consequently, swing-rotation motion is eliminated which is caused by the action of a point B as an exciting point because there is the centroid of the whole rotor 7 in the stator 2 as shown in a point a when non-load while there is also a location of the centroid in the stator 2 as shown in the point B when load that an impeller 11 is mounted is applied, thus lessening wear due to the swing-rotation motion while sharply decreasing the unevenness of revolution and noises.

Title: Water level controller
Inventor: YANAI NOBORU
IPC: G05D9/12
Filed: 1977-10-06
Abstract: PURPOSE: To stabilize the water level of dam to a command in the shortest time without causing the hunting when the quantity of inflow changes drastically.  
     CONSTITUTION: A gate 11 is provided for the dam 10. The quantity of discharged water is controlled depending on the degree of opening of the gate to vary the water level. The water level is detected by a level detector 13, whose output is supplied to a level discriminator 14, a variation rate discriminator 15 and an opening degree calculator 16. A set signal for a command level setting unit 17 is entered into the level discriminator 14, which discriminates whether or not the water level is within a predetermined range centering a command. The outputs of the variation rate discriminator 15 and the command level setting unit 17 are applied to the opening degree calculator 16. When the water level goes out of the command range, the cauculator 16 calculates the quantity of inflow from such an opening degree that the water level variation rate becomes zero, and calculates an opening degree necessary to restore the water level into the command range in the shortest time. The opening degree calculated is entered into a controller 18

Abstract: PURPOSE:To reduce the size of a device by providing a sheet turning over and returning means, turning over the sheets recorded on the front side and returning the same from a discharging part to the midway of a feeding line. CONSTITUTION:The copying sheet which is recorded on the front side is returned through a feed port 34 to the mid-way of a discharging line 20. The paper is turned over and returned at the speed higher than the ordinary processing speed of the sheet from the feeding part to the discharging part by a sheet turning over and returning means. The copying paper returned to the line 20 is again fed in the state of the rear side up into the transferring part, where the toner images on the drum 2 are again transferred on the rear side at an ordinary speed. The copying paper which is transferred with the toner images on the rear side is fed into a fixing device 17 by a conveying belt 23, and the toner images on the rear side are fixed to complete the recording on both sides. The paper is then discharged into a discharging part C. Thus the sheets are recorded on both sides continuously without the need for stacking and holding the sheets recorded on the front side once in an intermediate tray and since there is no  need for the intermediate tray, the device is made smaller in size.
