An apparatus for assembling a photo film unit has a dark box, which has supply openings into which parts are supplied, and an exit opening from which the body loaded with the photo film is exited. Intermediate cells of the dark box shield ambient light and include interlocked outer shutter plates and inner shutter plates which are disposed in the supply openings and the exit opening. A cassette supplying loader and a robot hand transfer the cassette into the dark box, while a leading tongue of the photo film is protruded from the cassette shell, with a remaining portion of the photo film contained as a roll. A roll forming fork device winds the photo film to a predetermined length from the cassette and forms the photo film into the roll. A photo film mounting mechanism swings the roll and the cassette shell together to change orientation thereof, and loads the roll and the cassette shell into the body.

A photo film cassette has a spool core (13) about which the photo film is wound in a roll form. A flexible disk (16, 17) is secured to each of two ends of the spool core, for regulating each of edges of the photo film. Material of the disk being thermoplastic synthetic resin sheet (27). The sheet is subjected to vacuum/air-pressure forming to form a disk-like portion (50). The disk is cut out of the disk-like portion by a punch/die set (31) before conveyance to a spool core mounting station. To inspect the disk, a photoelectric switch (54) includes a projector (54a) for applying a beam to a die of the punch/die set after cutting out the disk. A receiver (54b) measures the beam reflected by the die. A controller (55) evaluates the measured beam, to inspect occurrence of deposition of the disk on the punch/die set. If the deposition occurs, the controller considers the disk likely to overlie on one subsequent disk.

Inspecting method for disk used in photo film cassette

A dry type chemical analysis slide has a plurality of plate members formed of thermoplastic resin and a mount which holds a detecting element formed by the use of an electrode film and is integrally sandwiched between the plate members. At least one of the plate members is formed by extrusion.

Method of assembling chemical analysis slide

When arranging a plurality of sheets side by side in predetermined pattern on a sheet receiving member, the sheets are fed to a receiving position one by one, and are picked up one by one by a suction cup on a rotatable arm member. The rotatable arm member is rotated to bring each sheet picked up by the suction cup to a delivery position, and the sheet is placed on the part of the sheet receiving member positioned in the delivery position while the sheet receiving member is moved, in synchronization with rotation of the rotatable arm member, along a predetermined path corresponding to said predetermined pattern so that a new part of the sheet receiving member is brought to the delivery position each time the sheet receiving member is moved. This method is applicable to a process for making chemical analysis slides.

Method of and apparatus for arranging sheets

A chemical analysis slide includes at least two plastic sheets superposed one on another and bonded together, and a chemical analysis film sandwiched therebetween. In a method of continuously assembling such chemical analysis slides, while at least two plastic sheets in continous lengths are conveyed in the longitudinal direction thereof, a plurality of chemical anaylsis films are sandwiched between the plastic sheets at predetermined intervals, the plastic sheets are bonded together at a portion circumscribing each of the chemical analysis films sandwiched therebetween to form a sheet assembly and individual chemical analysis slides are cut out from the sheet assembly. At least one of the sheets in continuous lengths is provided with a plurality of slits extending in the transverse direction of the sheet at regular intervals at the remaining portions of the sheet which do not form a part of the chemical analysis slide.

An improvement of a device for measuring ion activity in a liquid sample comprising at least a pair of ion-selective electrode sheets, liquid-guiding portions for guiding a reference liquid and a liquid sample to each active surface of the pair of ion-selective electrode sheets respectively, and a bridge for electrically connecting both liquids supplied on the electrode sheets to each other is disclosed. Each ion-selective electrode sheet is arranged in such a manner that the active surface of the ion-selective electrode is placed upside down and each liquid guiding portion comprises a horizontal passage for conveying the liquid sample or the reference liquid supplied from the outside in the horizontal direction to the position just below the active surface of the ion-selective electrode, the horizontal passage being formed in a lower position than the active surface of the ion-selective electrode; and the horizontal passage is provided with a porous distributor which is bent to protrude upwardly from the horizontal passage up to the position just below the active surface of the ion-selective electrode so that the liquid sample or the reference liquid conveyed to the porous distributor can be brought into contact with the active surface of the electrode.

Ion activity measuring device

In a method of applying a precisely measured quantity of grease to a desired part, the grease is stored and leveled in an open grease storing container at all times, and a grease applying pin is dipped into the grease through its surface and pulled out of the grease and then moved so that the grease on the grease applying pin is applied to the desired part, whereby the grease is maintained high in quality and the quantity of grease applied does not fluctuate.

Grease applying method

A torsion spring having a coiled portion and straight ends is formed on a spindle by a winding machine with the coiled portion being wound around the spindle. A transfer device for transferring the torsion spring to a spring feeding position in which the torsion spring is fed to a spring inserting device receives the torsion spring directly from the spindle and transfers it to the spring feeding position keeping the torsion spring in a predetermined orientation.

Method of forming and feeding torsion springs

A method and apparatus for loading a recording medium such as a video magnetic tape into a magazine or cartridge employing an S-shaped running path. Both surfaces of the recording medium are placed over winding cores and held in the S-shape by stationary and movable forming pins. The reels of the winding cores are held so as to shift the assembly to a position above a body part of the magazine on a pallet transported by a conveyor belt. The assembly is then lowered so that the guide members forming the S-shaped running path are inserted into hollow lower end portions of the forming pins. The forming pins are then lifted from the guide members as the reels are released.
