Filed: 1996-04-16
Abstract: PROBLEM TO BE SOLVED: To provide a paper feeder, in which generation of vibration noise in a paper separation member can be prevented when paper is fed, for a printer. SOLUTION: In a recess part 73 storing a paper separation member 62 formed in a main body 60, the paper separation member 62 with a width larger than that of the recess part 73 is clampedly installed. In this case, the paper nipping direction T, which passes through a contact part between a friction pad 12 and a paper feeding roller 11 and through a rotation center 67 of the paper feeding roller 11, crosses the energizing direction U of a compression spring at a crossing angle C of about 4 degrees, and this crossing angle C is formed on the feeding side for a paper sheet 50 when the paper nipping direction T is used as a reference.  On the opposite side to the side on which the friction pad 12 is arranged in the paper separation member 62, a plurality of rib parts, which are brought into contact with a contact part with the main body 60 in the vicinity of an axial line binding two pivot shafts 63 together, are formed. The pivot shaft 63 for the paper separation member 62 is arranged on the feeding side for the paper sheet 50 when the paper nip position is used as a reference.

Title: Manufacturing method of leadframe for semiconductor device
Inventor: CHINDA SATOSHI
IPC: C25D5/18
Filed: 1994-06-02
Abstract: PURPOSE:To enable a palladium plated iron alloy material to sustain an excellent corrosion resistance by minimizing the pinholes made in an underneath layer of the palladium plating. CONSTITUTION:In order to manufacture the title lead frame For semiconductor device, the plating step is mandatory. Firstly, an Ni plating film is formed as an underneath plating palladium. Later, a palladium plating film or palladium alloy film is to be plated at least in an inner lead part and an outer lead part. Next, when an Ni plating film is formed, a pulse current is impressed so as to form an Ni plated film by pulse plating step. At this time, if the duty cycle 5-25% of the pulse waves is specified, the iron elusion amount is diminished below that of the specimen made by smooth DC so as to weaken the corrosion resistance i.e., the pin holes. Furthermore, if the period is specified to be 1-100ms, the iron elusion amount is relatively small down to the level posing no practical problems at all.
