摘要:
A cassette tape recorder including a fixed base plate formed therein with a capstan inserting hole, a pair of openings for reel spindles to extend therethrough, an opening for a recording and reproducing head and an erasing head to extend therethrough and an opening for a pinch roller to extend therethrough, and formed on its upper surface with cassette position regulating portions so that the upper surface serves as a cassette attaching surface. The fixed base plate has on its underside sliding movement guide portions for guiding sliding parts, fastening portions for parts to be fastened and mounting portions for mounting springs so that the underside of the fixed base plate serves as a working part mounting surface. The working parts of the recorder are mounted only on the underside of the fixed base plate in such a manner that a plurality of working parts are stacked one over another by assembling from one direction while the vertical relative positions of the mounted working parts are regulated and the capstan, reel spindles, etc. extend through the hole and openings in the fixed base plate to appear on the cassette attaching surface. Only the uppermost parts are fastened as by screw to the fastening portions of the fixed base plate.

An apparatus for mounting or fitting a tension coil spring onto spring retaining members of an article, said apparatus being adapted to restrain said spring at its both hook ends so that it may be stretched as it is conveyed from a supplying position to a mounting position, and to relieve the spring at said mounting position to allow the spring to shrink so that the spring may be delivered to the retaining members to be retained thereat.

A magnetic-tape running system for a video tape recorder having inclined pins and/or guide rollers having distant flanges. The pins and the guide rollers are inclined at suitable angles in the front and back directions and left and right directions so that the tape is guided only at its lower edge in such a manner that the tape runs stably along the cylinder lead at a constant contact pressure.

A magnetic recording and reproducing apparatus, in which a magnetic tape is automatically mounted on a tape guiding drum containing rotary magnetic heads for the recording and reproduction of signals on and from the tape, is provided with a pair of tape drawing and mounting members which are engageable with a tape in a cassette mounted on the apparatus and movable along guide slots in guide board to draw the tape out of the cassette to a position in which the tape is mounted on and extends around the tape guiding drum. The tape drawing and mounting members are operatively connected to chains. Drive mechanism is provided to wind and unwind the chains so that the chains are moved along guide members to thereby move the tape drawing and mounting members, respectively, away from the cassette for the required tape drawing and mounting operation.
摘要:
A method and a system for estimating an assembling-related fraction defective coefficient of an article in the stage preceding to manufacturing, e.g. at a stage of design. Assembling operation, properties/conditions of parts to be assembled and conditions of an assembling shop having significant influence to the likelihood of occurrence of failure in assembling work are inputted as data. Estimated value of assembling-related fraction defective is arithmetically determined with high accuracy by executing an assembling-related fraction defective value estimating program on the basis of the data as inputted.
摘要:
A designed object workability evaluating system for evaluating quantitatively at a stage of designing an article whether a structure of the article as designed can be realized with work easy to do in a manufacturing stage for thereby selectively determining a best structure from a plurality of design plans through comparative evaluation thereof. A server machine section of the system includes an evaluation-destined element estimating module for estimating the evaluation-destined elements to be performed on parts constituting an article given by a design plan subjected to evaluation, a part workability evaluation module for evaluating easiness of works to be performed on the parts, an article workability evaluation module for evaluating easiness of works involved in realizing the article, and a best design plan selection/determination module for selectively determining a best structure on the basis of comparative evaluation of a plurality of design plans.

A designed object workability evaluating system for evaluating quantitatively at a stage of designing an article whether a structure of the article as designed can be realized easily in a manufacturing stage for thereby selectively determining a best structure from a plurality of design plans through comparative evaluation thereof. The system includes a client machine section including a guide information generating unit for generating information for guiding operations of a user, an input device for allowing the user to input commands and data and a display unit. A server machine section includes a registering unit storing evaluation elements defined by the user, an index calculating module for calculating indexes indicating degrees of difficulty/ease of work, an evaluation element estimating module, a part workability evaluation module, an article workability evaluation module, and a best design plan selection/determination module.

Disclosed is a pick and place unit having a first moving plate movably supported by a fixed plate and a second movable moving plate supported by the first moving plate movably in the direction crossing the moving direction of the first moving plate. The pick and place unit comprises: a first rod-shaped member secured to the fixed plate and disposed along the moving direction of the first moving plate; a second rod-shaped member secured to the second moving plate and disposed along the moving direction of the second moving plate; a movable stopper secured to the first moving plate and having bores, each having portions different in width from each other, for receiving the first and second rod-shaped members respectively; a driving member for moving the movable stopper; and stators fixed at any desired positions of the first and second rod-shaped members, respectively, so as to sandwich the movable stopper and adapted to abut against the movable stopper.

A system for bringing a wire-shaped or tape-shaped carrier into contact with a carrier guide member in a predetermined position includes carrier withdrawing guide members each movable between an operative position in which the carrier is brought into contact with the carrier guide member and an inoperative position in which the carrier is out of contact with the carrier guide member. A plurality of strip-shaped power transmitting members formed to be flexible and connected at one end thereof to the carrier withdrawing guide members respectively are each slidably fitted in one of guide grooves of a guide groove member formed as an insert on the base. A drive connected to a motor is in engagement with the strip-shaped power transmitting members to drive the same and move the carrier withdrawing guide members connected to the strip-shaped power transmitting members, whereby the carrier withdrawing guide members can be moved between the operative and inoperative positions.
