Title: Magnetic tape cartridge
Inventor: SUMIYA KENJI
IPC: G11B5/627
Filed: 1986-03-05
Abstract: PURPOSE:To improve corrosion resistance of a magnetic tape by adding a leader tape provided with a rust preventive layer containing a rust preventive agent at least on one end of a magnetic tape having a magnetic layer that uses a metallic magnetic material as a recording element, winding it on a tape reel and mounting it in inside the body case of a magnetic tape cartridge. CONSTITUTION:A video tape 3 wound on a pair of left and right tape reels 2, 3 is made by forming a magnetic layer that makes a metallic magnetic material a recording element on a base of a polyester film etc., and a leader tape 4 added to the end of the tape 3 is constituted by forming a rust preventing layer containing rust preventive on a base. When the leader tape 4 provided with such a rust preventive layer is added to the end of the tape 3 having a magnetic layer that uses metallic magnetic material as a recording element, and mounted on the body case 1 of a magnetic tape cartridge for video, the rust preventive volatilizes from the rust preventive layer provided in the leader tape 4, and the body case 1 is filled with vapor of the rust preventive. Thus, the generation of rust is suppressed and corrosion resistance is improved sufficiently.

IPC: G01N17/00
Filed: 1978-04-25
Abstract: PURPOSE: To improve electrolyte dropping performance by providing a means of preventing the rise of electrolyte vapor evaporated from the sample below an electrolyte dropping nozzle.  
     CONSTITUTION: A sector form mask 8 having an electrolyte pass hole 8a is disposed below an electrolyte dropping nozzle 1 and is made turnable by a motor 7. Then, when pulses are transmitted to a solenoid value 3 from a power source 4, at the same instant when electrolyte is dropped from the dropping port 2 of the electrolyte dropping nozzle 1, the signal of a power source 4 is sent to a signal holding circuit 5, by which it is held for a fixed time, thence the power source output 6 is supplied to a motor 7 which in turn rotates the mask 8, causing the electrolyte pass hole 8a to deviate from right above the sample and the vapor of the electrolyte evaporated from the sample to disperse in the atmosphere without touching the dropping nozzle 1. Dewing near the dropping port 2 is thereby prevented and the stable dropping to the electrolyte at a fixed rate for a long time is accomplished.

SOLUTION: The melting point of an annular member is set to 300 deg.C or less, and the annular member is inserted between a rivet head and a fireproof expandable material. When the expandable material is fastened, the rivet is inserted into the annular member and is penetrated through the expandable material. Then, a rivet neck lower portion protruded from the lower portion of the expandable material is flattened out and fixed, and the spacer-like annular member is arranged between the rivet head and the expandable material. In this case, the rivet head is threaded and fixed into the rivet neck lower portion which has absorbed expansion of the expandable material in the width direction and has penetrated through the expandable material. The rivet is generally made of iron, and the annular member is made of aluminum. The surface of the iron rivet is coated with a resin layer.  Thus, even if the rivet is used in fastening the expandable material, sufficient fireproof heat insulating layer can be formed.

CONSTITUTION: When shafts 12, 14 are rotated by a driving chain 50 through sprockets 20, 22 during the operation of a drive mechanism, bushes 42, 44, 46, and 48 are rotated swingably in outer races of bearings 26, 28, 30, and 32 to rotationally move the rotation shafts 13 and 15 of the rollers to positions 13' and 15', and drive rollers 8, 10 are brought closer to each other to be moved to positions 8' and 10' indicated by broken lines. As a result, the distance between the rollers holding a handrail 18 is narrowed to increase nip pressure to the handrail 18. Thus, the tensile force of the chain 50 is increased in response to the increase in frictional resistance between the handrail 18 and a rail guide. As a result, a pair of opposed drive rollers 8, 10 are moved to be brought closer to each other, and to increase the driving force of the handrail 18.
