Title: Injection molder
Inventor: KAJIYAMA TAKASHI
IPC: B29C45/50
Filed: 1986-04-12
Abstract: PURPOSE:To obtain a molding, the molding strain of which is small and the surface accuracy of which is favorable, by a method wherein molding material is continuously poured in a mold by a primary injection pressure with any gradient in accordance with molding conditions. CONSTITUTION:Digital values corresponding to a primary injection pressure P1 and a secondary injection pressure P2 are inputted in advance from a keyboard 12 through a key interface 13 in a RAM 17 for storing and setting. In addition, the rise time t1 and the fall time t2 of the primary injection pressure are also stored and set in the RAM 17. The digital value of the primary injection pressure P1 or secondary injection pressure P2 is read out of the RAM 17 by an instruction issued from a CPU 11 at the injection process and outputted to a latch 18. The digital value from the latch 18 is converted by a D/A converter 19 into an analog value so as to be amplified by an amplifier 20 in order to drive a control valve 8, which controls hydraulic pressure at a pressure proportional to an input current. Accordingly, the rising and falling gradients of the primary injection pressure P1 can freely be set by increasing and decreasing the digital value outputted from the CPU 11 to the latch 18 with respect to time.

Title: Measurement system for call information
Inventor: ORITA SATOSHI
IPC: H04M3/36
Filed: 1985-04-19
Abstract: PURPOSE:To improve the precision of measurement without spoiling the profitability of a call information measuring function by calculating call information based upon the actual holding time of each call since 1 is added to a quotient according to the result of comparison of a remainder outputted by a dividing means with uniform uniform random numbers. CONSTITUTION:A dividing part 4' divides the holding time (t) transmitted from a holding time calculating part 2 by a unit time T transmitted from a unit time setting part 3 and transmits the quotient q(=[t/T]) to an integrating part 5 and the remainder r(=t-TXq) to a comparing part 8. A uniform random number generating part 7, on the other hand, generates a uniform random number R in a section [0, T] for every object of measurement on the basis of the unit time T transmitted from the unit time setting part 3 and transmits it to the comparing part 8. The remainder (r) outputted from the dividing part 4' together with the quotient (q) is not discarded and comparison information (c) obtained by the comparison with the uniform random number R is added to the quotient (q), so traffic intensity (a) outputted by a traffic intensity calculating part 6 is calculated on the basis of the actual holding time (t) of each object of measurement and the measurement precision is improved.

IPC: G01N29/24
Filed: 1998-03-30
Abstract: PROBLEM TO BE SOLVED: To provide an apparatus and a method, for an ultrasonic flaw detection, in which the influence of a noise is suppressed to a minimum even when a step-shaped array probe in a thin wedge shape is used and in which a defect existing near the surface of an object to be inspected can be detected accurately. SOLUTION: When a step-shaped array probe is used, many noises are contained in a place in which the time elapsed from the radiation of ultrasonic waves is short, and a noise component is reduced gradually as the time elapses. Before an actual flaw detection is performed, a standard test piece whose material is identical to that for an object, to be inspected, being inspected actually and which does not contain any defect at the inside is used. An inspection is performed in the same procedure as an inspection with reference to an ordinary object to be inspected, a signal is acquired, and the signal is used as a reference waveform so as to be stored in a memory 11 for reference waveform. Then, an ultrasonic flaw detection is performed to an actual object to be inspected.  A computing operation is performed to find a difference between a signal waveform obtained as its result and a signal regarding the standard test piece which is read out from the memory 11 for reference waveform.

IPC: G01C3/08
Filed: 1985-04-19
Abstract: PURPOSE:To sufficiently remove noise by separating and extracting a modulation component which is the carrier of an autofocus information by a band-pass filter circuit. CONSTITUTION:Noise is removed by separating and extracting only the modulation component of an autofocus information by passing a photoelectric signal from two divided photosensors 10a and 10b through shape band-pass filter circuits 17 and 28, said signal being produced from the beam of infrared rays reflected from an object to be photographed and being modulated by a constant frequency. Further, since a control is performed such that the quantity of light emitted from a light emitting diode 6 is reduced when the quantity of light reflected from the object is large and increased when the last-said quantity is small, only a necessary and minimum quantity of emitting light is required.
