Title: Manufacture of resin-sealed type semiconductor device
Inventor: SUZUKI HIROSHI
IPC: H01L23/50
Filed: 1987-12-25
Abstract: PURPOSE:To improve moisture resistance and thermal shock resistance by conducting resin seal by using a lead frame in which a metal in a lead frame is used previously as a cathode and electrolyzed in an electrolyte containing metal ions in current density close to or higher than limiting current density and the surface of the metal is changed into a roughened surface. CONSTITUTION:A metal in a lead frame is employed as a cathode, and electrolyzed in an electrolyte containing metal ions in current density close to or higher than limiting current density. Consequently, an infinite number of fine knurl-shaped deposits are formed to the surface of the metal, and the surface is turned into a roughened surface. Accordingly, a surface area is increased while adhesive properties with a sealant are improved by an anchoring effect, thus enhancing moisture resistance and thermal shock resistance. The Cu frame of a lead frame material is washed by 5% sulfuric acid and washed by water and employed as the cathode, a copper plate is used as an anode and an aqueous solution consisting of HBF245g/1, Na2AsO2.12H2Ophi100g/1 and CrO35g/1 is employed as the electrolyte, electrolytic treatment is performed for thirty sec in cathode current density of 7A/dm<2> at 12 deg.C, and the metal is washed sufficiently by water and dried.

Patent JP-H02179977-A (JP)
Title: Tape cassette
Inventor: SATO MASANORI
IPC: G11B23/087
Filed: 1988-12-29
Abstract: PURPOSE:To eliminate erroneous detection due to external light when a cassette enclosure is molded in a color other than a black and to color the cassette enclosure by surrounding a guide pole with a light shielding wall, and suppressing the irregular reflection of the light. CONSTITUTION:On a press-fit position 23 where a guide pole 9 on a supply reel side is press-fit and implanted, a light shielding wall 24 in a shape to surround the half circumferential surface of the guide pole 9 is formed. The light shielding wall 24 is formed so as to almost completely cover the half circumferential surface of the guide pole 9 on the side opposite to a magnetic tape sliding side, and its width is sufficient not to transmit the light. Consequently when the cassette enclosure is formed in the color other than the black, the external light is made incident inside through the cassette enclosure, since the light is shielded by the light shielding wall 24 and does not irradiate the circumferential surface of the guide pole 9, the irregular reflection of the light by the guide pole 9 can be prevented. Thus the erroneous detection of the external light by a light receiving element is eliminated, and the cassette enclosure can be colored, that is, the cassette enclosure can be formed in the colorful colors such as a blue and a red.

The light 20R reflected from the surface 30a is made incident to a line sensor 33, the output signal S of which is inputted to a measurement circuit 34. The circuit 34 fetches the signal S and compares the received light quantity of each photoreceptor element 33a with a reference value. When the received light quantity of each element 33a is larger than the reference value, it can be discriminated that the reflected light 20a is made incident to each element 33a. Namely, it is discriminated that the glass 30 exists at the incident position of the fluorescence. Therefore, the propriety of the cut length of the glass piece 30 can be detected.

Namely, while a monochromator MO is used and the wavelength of the light is varied at intervals of 2 nm, the light is made incident on the head FD which floats by the rotation of a quartz disk SD and light which interferes by the air layer FH between the disk SD and head FD is made incident on a detector RD. The quantity of the light which is incident on the detector RD is varied with wavelength, so the electric signal from the detector RD also varies. Therefore, the numerical proces sor SS processes the variation of the signal numerically to obtain the correct flotation quantity.
