Title: Manufacture of ultrahigh molecular weight polyethylene porous material
Inventor: MORIYAMA JUNICHI
IPC: B29K105/04
Filed: 1988-08-01
Abstract: PURPOSE:To easily obtain an ultrahigh molecular weight polyethylene (UHPE) mold having uniform porous degree by filling UHPE powder in a metal mold, heating it at a specific temperature, then regulating the density of the UHPE filled in the mold, then pressurizing, heating and further cooling it. CONSTITUTION:UHPE powder is filled in a metal mold and heated. If the heating temperature is in a range designated by a formula, it is not particularly limited. Its heating time can be altered depending upon the temperature, and is normally approx. 60 - 180min per 1cm of thickness of a blocklike porous material molded in the mold. After heating, the density of the UHPE filled in the mold is adjusted. This adjustment is to determined the porous degree of the material, and is normally conducted by a method of setting the height of the UHPE filled by the operation of pressure (approx. 0.3 - 40kg/cm<2>) to a predetermined value. After this adjustment, it is further pressurized and heated, then cooled to obtain a blocklike porous material.

Abstract: PROBLEM TO BE SOLVED: To allow scattering particles to be made to static-adhere to the dielec tric as a means for removing particles for collection by positioning the particle removing means around a susceptor when the inside of a reaction container is released at an atmospheric pressure or evacuated and by applying potential to an electrode by DC currecnt. SOLUTION: A particle removing means 11 provided with an annular dielectric 12 and circular electrode 13 is prepared around a susceptor 3. Supporting members 14 and 14' made of dielectric are attached to the means 11 and are connected with the electrode 13. The member 14 is connected to a DC power supply 16. A potential is applied to the electrode 13 through the DC power supply 16 to charge the dielectric 12. The scattered particles at this time are adhered to the dielectric 12 thanks to its static attracting force, thereby preventing a substrate 2 for forming a film thereon from particle contamination. The means 11 is lowered to the position of a dust receiver 17. In such a state, the applied potential of the metallic electrode 13 is set to reverse polarity or ground potential and the particles adhering on the dielectric 12 are dropped into the receiver 17.

IPC: B61L29/28
Filed: 1989-07-26
Abstract: PURPOSE:To simplify the constitution of the device by obtaining the top position of a train which is necessary for the constant time control for a railroad crossing from the number of axles which is detected by the detection signal supplied from an axle detector, on the assumption that each of the number of axles in one organization and one organization length has a fixed value. CONSTITUTION:In case of an ordinary train, the number of axles in one organization is four, and the one organization length l1-ln is 20m. Therefore, on the assumption of this fact, the number of axles is counted on the basis of the detection signals of the axles 4 and 5, and the top position of the train after the passing on the detectors 4 and 5 is calculated. The train speed is calculated from the time when a same axle passes through the detectors 4 and 5. The time necessary for the arrival of the top of a train 2 at a railroad crossing and the delay time which is obtained by subtrating the min. alarm time from the above-described time are calculated from the train speed and the number of axles. The railroad crossing control condition is sent into a railroad crossing device 7 according to the lapse of the above-discribed delay time from the delay time setting part 64 of a constant time setting device 6 for the railroad crossing, and the device 7 is started. In this case, the min. alarm time is secured.

IPC: G11B7/2433
Filed: 1988-08-03
Abstract: PURPOSE:To improve repetitive characteristics of writing and erasing by allowing many dotty metallic layers to exist at the boundary between an optical recording layer and a dielectric layer. CONSTITUTION:The dielectric layer 2 is formed on the surface of a substrate 1 and further, the recording layer 3 and the dielectric layer 4 are formed thereon. The dotty metallic layers 5 are formed on the dielectric layer 2 by sputtering or vapor deposition of a high melting point metal such as Ni, Au or Pt prior to vapor deposition or sputtering of the recording layer 3 consisting of a GeTe compd. on said layer. Further, the dotty metallic layers 6 are formed by the similar method on the recording layer 3 prior to sputtering, etc., of the dielectric layer 4. Crystallization progresses rapidly as there are already the spots to constitute crystal nuclei if the recording spots in an amorphous state are irradiated with laser light. Execution of many times of the repetition of writing and erasing is thus possible.

IPC: G06K9/68
Filed: 1987-08-04
Abstract: PURPOSE:To accurately recognize a hand written input character without generating misrecognition by registering a new recognition pattern inherent in a user in a character dictionary part and registering also stroke importance degree information. CONSTITUTION:A character segmenting part 3 detects an input to an input tablet 1 by an input pen 2 to decide the input of one character, and when a character is inputted, outputs the input to a feature extracting part 4. The extracting part 4 extracts input features from the number of strokes, the coordinates of an end point of a stroke, the shape of the stroke, etc., and sends the extracted features to a stroke analyzing part 5. The analyzing part 5 executes stroke analyzing processing while referring a stroke dictionary part 6 to specify a stroke code. A character recognizing part recognizes the character based on the stroke code by referring a character dictionary 8 and a stroke difference degree table 9. Since the character dictionary part 8 has a user registration character part 12 in addition to a reference character part 11, the pattern of the character part 12 is determined with priority.

IPC: G06F11/34
Filed: 1990-07-23
Abstract: PURPOSE:To decrease the number of memory elements needed for recording by recording the clock data after converting them into a serial form. CONSTITUTION:The external data to be recorded are collected by a data collecting part 4 and then recorded into a data memory DM 2 when the recording conditions are decided. At the same time, the data obtained by converting the value of a clock 5 into a serial form by a serial converter 6 are recorded into a time memory TM 3 corresponding to the DM 2 as long as the TM 3 is idle. Then a counter 1 is counted up and the recording conditions of the next data are decided. Thus it is possible to read later the recorded data out of both memories DM 2 and TM 3 and to serially read out the time points when the events are produced. As a result, the clock output data 18 corresponding to each output data 17 are obtained in Nos 12, 13, 15, 17 and 19 by a conventional technique. In this example, however, the clock output data 8 are obtained in Nos 12, 15 and 19 and therefore the number of memory elements can be reduced.

Abstract: PURPOSE:To prevent time-out caused by the stop of transmission and reception of a data between a transmission side and a reception side, by transmitting the data at data processing speed or below by the receiving side, when a transmission time and a data quantity accumulated in a buffer memory after a data transmission are started exceed a threshold level. CONSTITUTION:When the remaining quantity of a data in a buffer memory 6 of a data transmission equipment 8 of a reception side exceeds a threshold level, the speed for transmitting a data to the data transmission equipment 8 of the reception side from the data transmission equipment 7 of a transmission side is controlled so as to become a little lower than read-out speed from the buffer memory 6. Accordingly, the data in the buffer memory 6 can be decreased gradually. In such a way, time-out caused by the stop of transmission and reception of the data between the transmission side and the reception side can be prevented.
