  • Patent number: 5905980
    Abstract: The present invention provides a document processing apparatus, word extracting apparatus, word extracting method and storage medium for storing a word extracting program, capable of appropriately presenting effective associate words to the user. A retrieving element executes retrieval of documents based on a retrieval condition inputted through a retrieval condition inputting element. A keyword designating element designates an arbitrary word among the words included in the retrieved documents as an associate-word-searching word and designates other words as candidates for an associate word. A simultaneous appearance probability calculating element calculates a simultaneous appearance probability of the associate-word-searching word and one of the candidates for the associate word in any of the retrieved documents. A first independent appearance probability calculating element obtains an independent appearance probability of the associate-word-searching word in each of all documents.

  • Patent number: 5171293
    Abstract: A fuse box assembly including a fuse box and a fuse holder. The fuse holder has a saddle configuration and overlies one of the terminal sockets of the fuse box. The fuse holder includes an opening to receive the body of a fuse and the fuse holder is mounted on the fuse box for movement between an operative position in which the terminal tabs of the fuse are received in the associated terminal socket of the fuse box and a raised, inoperative position in which the terminal tabs of the fuse are removed from the terminal socket. The holder includes a pair of legs which extend downwardly along opposite side walls of the fuse box and which include slots which coact with pins on the side walls of the fuse box to provide a detenting action to positively maintain the holder in its raised, inoperative position.

  • Patent number: 4842801
    Abstract: A switching control method which can smoothly effect transfer from a pressure holding step to a metering and kneading step in an injection-molding machine employing a servomotor as an injection shaft driving source for axially driving a screw. At completion of the pressure holding step, follow-up of an error register of a servo circuit driving the injection shaft servomotor is effected so as to bring an error amount accumulated within the error register to zero (steps S6 to S8). A value of torque limit acting on the servomotor is then switched from a set value for pressure holding to a set value for metering and kneading (step S11). Further, the follow-up of the error register is again executed over a predetermined period of time from the time of execution of the switching of the torque limit (step S13). Subsequently, transfer is effected to the metering and kneading step (step S14).

  • Patent number: 4812268
    Abstract: A suckback method and apparatus is capable of positively effecting a suckback operation in an injection molding machine using a servomotor as an injection axis drive source for axially driving a screw. When the screw reaches a metering completion position, screw rotation is stopped and a follow-up operation for an error register is carried out so that an error amount accumulated in the error register becomes equal to zero (steps S1, S4, S5). Then, a torque limit for the servomotor and for application of back pressure is released (step S8), and the screw is driven backwardly by the servomotor by a predetermined suckback amount (step 11).

  • Patent number: 4639693
    Abstract: An improved strip line cable for transmission of electromagnetic waves in the millimeter wave length range is provided. The cable has a plurality of face to face conductors in pairs, the conductors being separated from their paired counterparts by a porous plastic dielectric insulation material. The cable is jacketed. The improvement comprises the porous plastic dielectric material being, in addition, placed between each conductor and the jacketing material, thereby resulting in each conductor being effectively surrounded by porous plastic dielectric insulating material.

  • Patent number: 4629351
    Abstract: A new fitting indicating mechanism in screw type connector housings is provided. Said mechanism comprises a male connector housing having an engaging portion; a female connector housing having cavity means for receiving said engaging portion therewithin; a tubular body having a bore contiguous to said cavity means and a plurality of flexible support arms extending into said bore toward a direction opposite to said female connection housing; and an indicator rod held to extend within said cavity means and said bore, said indicator rod being biased toward the male connector housing such that said flexible support arms covers the indicator rod when fitting engagement of both housing connectors is not completed but pushes open said flexible support arms upon completion thereof such that said indicator rod is exposed out the flexible arms.
