Abstract: PROBLEM TO BE SOLVED: To provide an iron piece detector which can excellently perform detecting operations even when an unnecessary magnetic field exists on the outside. SOLUTION: While an object Dx to be detected is moved at a preset constant speed V by means of a transferring belt in a direction obliquely crossing DC magnetic fluxes in a DC magnetic field H generated from a permanent magnet 1, first and second detect signals respectively generated from first and second detecting coils 3 and 4 provided at a prescribed interval in the moving direction of the object Dx when the magnetic fluxes generated from the magnet 1 and passed through the object Dx obliquely intersect the windings of the coils 3 and 4 are respectively converted into digital signals by means of A/D converters 13 and 14.  An arithmetic section 18 computes the autocorrelated relation of the difference signal between the two digital signals outputted from the converters 13 and 14 and, when the computed result is larger than a preset threshold, generates an iron piece detecting output signal and gives the output signal to an output section 19.

Title: Control method for injection molding machine
Inventor: ISHIKAWA ATSUSHI
IPC: B29C45/70
Filed: 1993-10-01
Abstract: PURPOSE:To eliminate the necessary for determination of a set value and input work for starting an injection compression. CONSTITUTION:A control method comprises a distance sensor 28 for sensing the distance between platens, a pressure sensor 27 for sensing the mold clamping force to a mold and a microprocessing unit 43 for performing the preset control by utilizing distance sensing signals from the distance sensor and pressure sensing signals from the pressure sensor. The distance L between platens, which becomes greater as the resin filling advances, is monitored by the microprocessing unit after the filling process is changed over to the dwelling process, and when the distance reaches a preset value LE, a driving source is so controlled as to retain the mold clamping force at that time. The inflection point in the decreasing of the distance L between platens following the shrinkage generated by the controlling and solidifying of resin the mold thereafter is sensed, and the injection compression molding is started.

Title: Signal format of picture signal, method and device for converting format of picture signal
Inventor: HORI AKIHIRO
IPC: H04N19/00
Filed: 1996-09-19
Abstract: PROBLEM TO BE SOLVED: To easily execute picture processing by a computer, to obtain a picture signal which can easily execute data compression and to convert the signal format of a television signal and a conventional picture signal into the picture signal by specifying the number of effective scanning lines and the number of effective horizontal picture elements, which are the signal formats of the picture signal. SOLUTION: In a screen whose aspect ratio is 16:9, the number of the effective scanning lines is set to 480 and the number of the effective horizontal picture elements to 684. The number of the effective scanning lines by a conventional sequential scanning system whose aspect ratio is 16:9 is set to be 480. For obtaining the square picture elements without changing the number of the effective scanning lines, the number of the picture elements satisfies the number of the picture elements =16/9× 480 = 853.3. When the number of the horizontal effective picture elements is set to about 853.3, the respective picture elements become square and the picture processing in the computer can easily be executed.  Since it is convenient that the number of the picture elements is the multiple of 16, the number of the picture elements is set to be 864 which is approximated to about 853 and it is the multiple of 16.
