Title: Signal discriminating circuit
Inventor: MUNEKI KOUICHIROU
IPC: G01N21/88
Filed: 1982-10-20
Abstract: PURPOSE:To obtain signal discriminating circuit which can detect a desired pulse, by converting an image pickup signal into a continuous pulse train signal with a delaying/differentiating operation and extracting only a high band pulse out of the interval of each pulse. CONSTITUTION:An original signal shown in a figure (a) is delayed and differentiated to be converted into a signal B containing a positive pulse P and then a negative pulse N as shown in a figure (c). The positive pulse signal P is compared with the voltage of a level C1 by a comparator 41 and then binary coded as shown in a figure (d). While the signal N of the signal B is inverted by an inverter 5 and then compared with a voltage level C2 by a comparator 42 to be binary coded as shown in a figure (e). A mono-multi 61 delivers a signal E1 having a fixed time width synchronously with the rise of a signal D1 as shown in a figure (f). Usually it is considered that the longer the time difference between continuous positive and negative pulses P and N the lower the level of a low band pulse. Therefore, an output is obtained through an AND gate 71 only with a high band pulse by obtaining an AND between signals E1 and D2.

IPC: H04N9/85
Filed: 1993-07-23
Abstract: PURPOSE:To make optional reproduction disable by differentiating the access order of addresses of a memory in a prescribed relation at write/read. CONSTITUTION:A video signal is fed to field memories 3a, 3b for each sample. The memory 3a is connected to a controller 7 and the memory 3b is connected to a read controller 9 in a 1st field of a video signal by a changeover controller 13.

Title: Inferring method of production system
Inventor: KAWABE MITSUNORI
IPC: G06N5/04
Filed: 1994-07-11
Abstract: PURPOSE:To prevent an unnecessary rule from being fired without interrupting a recognition-execution cycle by deleting other instantiation which belongs to the same rule set with selected instantiation or suppressing firing in next and succeeding cycles. CONSTITUTION:A production rule is divided into plural rule sets by a rule writer. An inference engine performs collation 1 and conflict elimination 2 as and selects single instantiation out of a conflict set by conventional conflict elimination strategy. Then when instantiation belonging to the same rule set with the instantiation is left in the conflict set, an exclusive rule deletion part 3 deletes the instantiation from the conflict set or gives a firing disabling mark etc., to suppress firing in the next and succeeding cycles. Consequently, only one rule in the rule set can be fired and the firing of unnecessary rules in the next and succeeding cycles can be suppressed.

Title: Controlling method for pipeline arithmetic device
Inventor: MOGI MASANORI
IPC: G06F9/38
Filed: 1980-12-26
Abstract: PURPOSE:To process data successively at series-connected arithmetic stages by initially setting the number of elements in a counter for every time and by obtaining the output timing of a prescience signal on a case-by-case basis. CONSTITUTION:The number EN of elements is preset in a counter 31. The 1st corresponding data is also set in the registers R2A and R3A of a stage A. While the data is shifted down, stage by stage, synchronizing with a one-cycle clock CC, the contents of the counter 31 are decreased, one by one, by a decrement means 32. When operation is started for prescience once the count value of the counter 31 reaches one, a decoder 33 outputs logic ''1'' on detecting that. The output of the detecting circuit 34 of a following stage B is inverted on the reception of the logic ''1'' to generate a prescience signal. The prescience signal W shows that data D1 is outputted from a register R1D.

Title: Injection molding machine
Inventor: SONODA YUBUN
IPC: B29C45/82
Filed: 1986-08-05
Abstract: PURPOSE:To contrive an improvement in preservation properties of press supply equipment and a hydraulic fluid supply system by enabling relief of surplus pressure from a material side acting upon the press supply equipment, by providing a relief valve on the hydraulic fluid supply system of the material press supply equipment. CONSTITUTION:A material is sent to the front by passing through the outside circumferential part of a plunger 24 and accumulated in order within a barrel 22 in front of the plunger 24 by passing through a check ring part 23. The resin material of the circumference of the plunger 24 is homogenized by a rotation of the plunger 24 and a short-circuit of a flow path of the material is prevented. In addition, as the material is sent even to an upper side of the plunger 24 from a lower side or even to the lower side from the upper side while the material is being turned in, even a part of the material hard to flow or the material hard to flow does not stay within the barrel 22 and the material extending over the whole of the whole circumference of the inside of the barrel 22 is transferred smooth. Then when hydraulic pressure of the inside of a pipe line 81 exceeds preset pressure by acting excessive pressure (push up force) upon a stuffer plunger 30, a relief valve 89 is released and the pressure is freed. Therefore, break of a stuffer and hydraulic system due to excessive pressure is prevented.
