Patent JP-H0737921-A (JP)
Title: Semiconductor device
Inventor: KOBAYASHI HIROTAKA
IPC: H01L23/28
Filed: 1993-07-23
Abstract: PURPOSE:To prevent the occurrence of wire sweep of bonding wires by reinforcing the bonding wires by connecting the bonding wires transversely to each other with electric insulating reinforcing material. CONSTITUTION:After a wire-bonding process, while the temperature of a bonding wire 24 is still high, a reinforcing tape 32 is put on the bonding wire 24 with an adhesive layer 34 faced downwards. After attaching the reinforcing tape 32 to the bonding wire 24, a semiconductor chip 10 and a lead frame 12, which are connected to each other with bonding wires 24, are so sealed into one body with sealing resin that outer leads 18 may be exposed. Due to this structure, the bonding wires 24 are linked to each other with the reinforcing tape 32 and thereby are made into one strong-structured body and furthermore, the length of one bonding wire 24 which needs to be supported is made shorter by the reinforcing tape 32. By this method, wire sweep to be caused by injection pressure of sealing resin 26 is avoided.

Title: Arc tube for high-pressure sodium lamp and optically transparent polycrystalline alumina sintered body
Inventor: WEI GEORGE C
IPC: H01J61/30
Filed: 1997-07-29
Abstract: PROBLEM TO BE SOLVED: To improve efficiency and modify a lumen maintenance rate by employing an optically translucent multiple crystal body essentially constituted by specified amounts of magnesia, zirconia, yttoria. SOLUTION: A high-pressure sodium lamp 100 has an internal bulb container or an arc tube 14 positioned at the center of an external bulb container 6. The tube 14 is composed of a ceramic that transmits one light formed from polycrystalline alumina ceramic that is translucent and contains about 0.020 to 0.050wt.% of magnesia, about 0.018wt.% of zirconia, and about 0.035wt.% of yttoria, and the remaining alumina. By mixing zirconia, formation of spinel is restricted during lamp operation and processing, so that loss of sodium can be decreased. Since a wall body temperature can be risen, 2 to 3% of yield of lumen can be obtained by an increase of temperature of 50 deg.C. Consequently, an improved efficiency can be obtained.

Title: Inspecting device for cold emission of picture tube
Inventor: NAGASHIMA HITOSHI
IPC: H01J9/42
Filed: 1985-09-13
Abstract: PURPOSE:To make easier the inspection for cold emission by shielding the neck part of a picture tube and then detecting light focused from the neck part by cold emission with a photosensor. CONSTITUTION:Light emitted by cold emission at the neck part 1a of a color picture tube is focused by focusing parts 9, 10. The light focused here is guided to a low-level light detection and discrimination part 13 by optical fibers 11, 12 and emission of light by cold emission is detected at such low-level light detection and discrimination part 13. In this case, since the neck part 1a is shield, external light is not applied to the focusing portions 9, 10 and the low- level light detection and discrimination part may not be disturbed such external light. Thereby, the low level light emission by cold emission at the next part may be detected sufficiently.

IPC: H01C10/00
Filed: 1992-07-31
Abstract: PURPOSE:To enable fixing electronic components easily without using thermal fusion-bonding, by inserting both peripheral parts of the fixing part of a metal terminal in the insertion direction along a pair of guide grooves formed at a pair of standing parts for fixing a terminal, and making an engaging segment formed at both of the peripheral parts engage with a part to be engaged which is formed in a pair of the guide groove. CONSTITUTION:When a metal terminal 7 is inserted into a guide groove 12b so as to make a connection part 73 be a top, the terminal is smoothly inserted until an engaging segment 72 is inserted into the guide groove 12b. When an engaging segment 72c enters the guide groove 12b, the engaging segment 72c proceeds while extending a pair of standing parts 12a, 12a for fixing a terminal. When the engaging segment 72c engages with a slit 12c, a pair of the standing parts 12a, 12a which are extended return to the initial state, and an engaging part 72c2 of the engaging segment 72c engages with a division surface 12d, thereby preventing the metal terminal 7 from coming out. Hence the metal terminal can be easily fixed to a terminal fixing part, finish is excellent after the metal terminal is fixed, and yield is improved.
