摘要： A cartridge receiving casing capable of permitting a cartridge to be readily removed from the casing by one hand as required while preventing the cartridge from accidentally falling off from the casing. The casing includes a casing body formed so as to be open on one side thereof to provide the casing with an opening through which a cartridge is inserted into and taken out of the casing and a cover slidably arranged on the casing body. The cartridge is engaged with first projections of stoppers at a received position, to thereby be elastically supported in the casing. When the cover is slid to an intermediate position toward the opening, the cartridge is partially exposed through the opening and elastically supported while being drawable out of the casing. Further sliding of the cover permits the cartridge to be removed from the casing.

摘要： A reel spring for tape cassettes includes at least two mounting holes which are formed in the base portion at opposite sides with respect to a tape reel centerline connecting reel centers and in such a manner to be spaced in the direction of the tape reel centerline, and which is used for melt-bonding with the cassette housing. The base portion is arranged so as to have a center laid on the tape reel centerlines, respective end portions are arranged so as to have their centerlines passed through respective contact points for urging a pair of tape reels, extended in parallel with each other and deviated with respect to the tape reel centerlines. The width of the base portion is substantially the same as that of the end portions. The reel spring is prepared through a cutting step for cutting a stock up to positioning holes from opposite edges of the stock so that the cutting is made with the same width as the width of a reel spring end portion, along separation lines which deviate with respect to the tape reel centerline, extend in parallel with one another and pass in the vicinity of the mounting holes, the separation lines including separation lines for reel spring end portions at one side and separation lines for reel spring end portions at the other side which are out of alignment.

摘要： A plasma-polymerized film is formed by depositing and polymerizing a metal element-containing material forming an electrode and a gaseous polymerizable carbon-containing reactant in a plasma atmosphere. The polymerized film contains the metal element Mt and carbon C in an atomic ratio Mt/(C+Mt) of at least 1/100. The polymerized film is prepared under a condition W/(F.M) of at least 10.sup.8 joule/kg wherein W is a power applied for plasma generation in joule/sec., F is a flow rate of the gaseous reactant, and M is the molecular weight of the gaseous reactant, F.M being expressed in kg/sec. Such a polymerized film is advantageously applied as a coating to a surface of a member which constructs or is disposed in a casing in which a tape or disk-shaped medium is received for travel or rotating motion.
