Title: Paper roll feeding device
Inventor: NISHITSUJI HIDEFUMI
IPC: B65H7/06
Filed: 1987-04-16
Abstract: PURPOSE:To perform accurate paper feed and prevent incorrect jam detection by gradually increasing the rotation of a paper feed roller by a paper feed buildup control means at a speed commensurate with the inertia of the paper roll, thereby changing the jam detection time according to the speed. CONSTITUTION:Paper rolls P1-P3, with their paper roll characteristics detected by paper size sensors 11-13, paper kind sensors, and paper roll remaining amount sensors Q1-Q3, are fed by changing buildup times of motors 51-53 according to the paper roll characteristics so that the speeds of paper feed rollers 6, 10, 14 are gradually increased at the time of starting rotation. A time from when the paper is unwound from the paper rolls P1-P3 to when the paper reaches the paper size sensors 11-13 and a jam detection time to when the paper reaches sensors G1-G3 are changed according to the amount of change in time for the buildup by a paper feed buildup control means. In this way, no paper slip or the like occurs even if the inertia of the paper rolls changes to perform always accurate paper feed and to prevent incorrect actuation of paper jam detection.

IPC: E04B7/00
Filed: 1997-04-10
Abstract: PROBLEM TO BE SOLVED: To provide a method of designing an overhang length of an all-weather berth overhung roof in accordance with the required operation rate of individual cargo handling facilities. SOLUTION: Actual data for wind speeds S(t0 ) and rainfall intensities W(t0 ) at individual times t0 are used to calculate the amount of rainfall W'(t0 ) entering a working area at the overhang length L of an overhung roof, assuming that it is L0 , from weather data for one or more past year at a planned all-weather berth installation place and compare it with an upper limit value for the amont of rainfall, possible for cargo handling work, so that judgement that it is workable or not at a time t0 is made. If judgement that it is workable is made, judgement that it is workable in a time section including the time t0 is made. Similarly, a workable time in a specified period (t=t0 through tmax ) for at least one year is calculated and the total is divided by all time in the specified period to calculate an operation rate F0 .  The L0 is gradually increased from an initial value 0 to calculate the operation rate F0 in sequence and the L0 value at the time when the required operation rate is Freq or more is employed as a value for an overhang length in design.

IPC: H03M13/00
Filed: 1987-04-15
Abstract: PURPOSE:To speed up an error detecting processing and to detect the error of data before transmitting data by using a read-solomon code in a byte unit as a cyclic, redundancy, check code for error detection and executing a CRC processing in parallel with the error correction of data. CONSTITUTION:By using the read-solomon code for error detection in a byte unit, (n) data XOR (exclusive OR) accumulative addition is executed at every continuous (n) pieces of data, and the size and the position of the error with respect to (m) pieces of data at every other (n) data is obtained so as to execute error correction. The size of the error is XOR-added and corrected to the result of the (n) data XOR cumulative addition corresponding to the position of data. After repeating it, final (m) pieces of corrected (n) data XOR cumulative addition results and (p) pieces of error detection parities in a byte unit are divided by a generated polynominal and the error is detected by whether the remainder is zero or non-zero. Thus, error detection is executed at high speed and the check of error detection is attained before transferring data from a buffer memory to a host computer.

Title: Parison thickness setting method
Inventor: KOHAMA YUKINORI
IPC: B29B11/10
Filed: 1994-05-02
Abstract: PURPOSE:To prevent shear of thickness at a product section of a parison in the longitudinal direction by stopping discharge of the parison after a lapse of time that the bottom end of the parison reaches a predetermined terminal position. CONSTITUTION:Discharging of a parison is started and the parison descends at a fixed descending speed. When the bottom end of the parison reaches a height of an optical sensor 20, the optical sensor 20 detects it and sends a signal to a control device. A pre-pinch device 30 is moved forward so as to pre-pinch the parison P and quantity of die gap of the parison thickness is controlled so as to change from a start point b1 till a terminal point b2 in sequence. At the time that the parison P reaches an entire length L, the discharging of the parison P is stopped. Thus, the parison P changes in thickness. In a stage of mold clamping, a length corresponding to a product section B among the thickness changes is pinched by a pair of right and left molds 8A, 8B for molding, so that an obtained product has a desired thickness change, thereby saving resources and improving yield.
