Filed: 1991-04-18
Abstract: PURPOSE:To improve the flowability of a metallic powder and to carry out compression-molding to mold a high-density sintered body by using an appropriate binder to granulate the powder. CONSTITUTION:An org. binder contg. a resin having a unit shown by the formula (R1 and R2 are independently selected from a hydrogen atom and hydrocarbonic groups) is mixed into a metallic powder (contg. graphite powder and nonmetallic powder having 1-18mu particle size) to produce a metallic granulated powder for powder metallurgy. Meanwhile, 1-18C hydrocarbonic groups (alkyl, cycloalkyl and phenyl groups) are preferably used as R1 and R2, and 6-34vol.% of the org. binder is used. Polyvinyl formal, polyvinyl butyral, etc., are used as the resin, and the particle size of the granulated powder is preferably controlled to >= about 40mu.

Title: Method for preventing alterlation of prepaid magnetic card
Inventor: KUSAKABE MAKOTO
IPC: B42D15/10
Filed: 1996-03-06
Abstract: PROBLEM TO BE SOLVED: To prevent the alteration of a magnetic card by providing a magnetic recording place of remaining register frequency, etc., and a punch hole place showing its mark, arranging them at the same part, magnetically recording information from a remaining register frequency record starting position and opening a punch hole at the starting position of former magnetic recording. SOLUTION: Prepaid magnetic card 1 consists of the magnetic recording place 2, the punch hole place 3, an optical reading code 4, a magnetic recording data 5 and the punch hole 6. When the number of remaining registered frequencies are reduced, a punch hole 6 is opened at a position corresponding to the registered frequency. In addition the magnetic record starting position of magnetic recording data 5 is also changed to a fixed position corresponding to the remaining registered frequencies to record the remaining registered frequencies, etc. Thereby, the punch hole is opened at the starting position of fixed magnetic recording corresponding to information on the remaining registered frequency, etc.  Then even if trying to magnetically record information increased in the registering frequencies to the card reduced in registered frequencies, as the punch hole is opened at the normal magnetic record starting position, magnetic recording is prevented and if repairing the punch hole by a material in the same shape, patching prevents recording.
