Title: Plating structure of bonding part
Inventor: HAYASHIDA HIDENORI
IPC: C25D5/24
Filed: 1997-04-14
Abstract: PROBLEM TO BE SOLVED: To form plating layers having a high bonding property without using Ni-P plating by plating Ni-B of a specific thickness as ground surface plating on the soldering parts and bonding parts of semiconductors and electronic parts and plating Pd thereon at a specific thickness. SOLUTION: The Ni-B plating contg. 0.01 to 10% B is first formed at a thickness of 0.01 to 20 μm on the soldering parts and wire bonding parts of the electronic parts, such as semiconductor elements and lead frames. The Pd is then plated at a thickness of 0.005 to 10 μm thereon and further, in some cases, Au is plated in superposing thereon at a thickness of 0.005 to 5 μm. The plating having a good bonding property, such as the excellent resistivity to solder erosion, good wettability of deposited metal, high strength of adhesion, excellent heat resistance, etc., may be formed without applying the Ni-P which is used thus far as the ground surface plating and has defects. The quality and the reliability of semiconductors and electronic parts are improved.

Title: Information recorder
Inventor: YOSHIMOTO ITSURO
IPC: G11B20/10
Filed: 1990-05-22
Abstract: PURPOSE:To eliminate the need of manual switching by reading a code showing the inhibition of copying and automatically selecting one of a signal from an analog input terminal and a signal from a digital input terminal corresponding to the read result. CONSTITUTION:When the second pit of a control code is zero (digital copying is inhibited), the category code is read. When the category code shows a CD, general, a PCM encoder/decoder or the like, the digital copying is executed. When the category code shows a digital audio tape recorder (DAT), a signal processing part 2 is controlled by a control part 14 and a signal inputted from an A/D conversion part 1 is selected. Due to that, the signal inputted from the conversion part 1 is recorded on a magnetic tape 7. Therefore, the code showing the inhibition of the copying is read and one of the signal from the analog input terminal 8 and the signal from the digital input terminal 9 is selected corresponding to the read result. Thus, the need of the manual switching is eliminated.

Title: Cutting tool and its mounting means for asymmetric groove
Inventor: KOJIMA KATSUMI
IPC: B23D43/00
Filed: 1987-05-28
Abstract: PURPOSE:To enable a tool, which enables high accurate cutting to be performed suppressing a change of resistance of cutting with no overcutting, to be mounted with no deformation and no residual cutting by fixing the tool, having an edge part with an included angle and a flat edge part without an included angle, to a holder from a long groove side. CONSTITUTION:A broach 2, providing an edge area C without an included angle, eliminates an overcutting area X when the broach 2 is clearly extracted. While the broach, simultaneously providing an edge part area D with an included angle and an area C serving as the flat edge part without an included angle in one edge, performs roughing by the edge part D of small resistance of cutting and decreases a cutting margin by the edge part C, enabling stable cutting of small resistance to be performed. Next the broach 2, when it cuts an asymmetric groove, is tightened to be fixed to a broach holder 1 by a screw thread 9 from a delivery hole side of the longer groove, cutting the groove having an asymmetric shape. In this way, closely attaching a thick line part 2b, the broach 2, effectively preventing its deformation, enables the asymmetric groove to be finished with no residual cutting.

Title: Thermal head
Inventor: MIURA AKIRA
IPC: B41J2/35
Filed: 1981-08-26
Abstract: PURPOSE:To obtain a thermal head capable of improving the quality of recording with an equalized temperature distribution by employing a heat self-generating body with a thermal oxide formed on the surface thereof. CONSTITUTION:A heat generating body to be adjusted is so controlled with a signal SR and signal SX that when the signal SR corresponding to the reference resistance value and the signal SX corresponding to the resistance value of the heat generating body are SR>SX, it is energized to generate heat and when they become SR<=SX, the energization thereof is stopped. The surface of the heat generating body is exposed to the oxidizing atmosphere, where an oxide is formed on the surface thereof with a heat generated by the body itself. At the start of the energization, it generates heat evenly as current flows uniformly through the entire body. But as the temperature at the center thereof goes higher than the perimeter, the terminal oxidation is promoted all the more. This makes the temperature distribution during the recording higher in the perimeter than at the center thereby equalizing the temperature distribution of the thermal head.
