IPC: H01L23/50
Filed: 1996-05-08
Abstract: PROBLEM TO BE SOLVED: To prevent occurrence of package cracking when an LSI package of a lead-on-chip(LOC) structure having a bus lead is subjected to a temperature cycle test. SOLUTION: The resin-sealed LSI package of an LOC structure has inner leads 16 and a bus bar lead 18-1 disposed on the major surface of a semiconductor chip 13 through an insulating tape 14, and bonding wires 19 connected between the inner leads 16 and bus bar lead 18-1 and bonding pads 15 of the semiconductor chip 13, cut lines 21 extending in a direction perpendicular to a longer side of the semiconductor chip 13 are made in the insulating tape 14 between pitches of the inner leads 16.

Title: Alarm clock
Inventor: OKUYAMA KENJI
IPC: G04C21/16
Filed: 1981-08-31
Abstract: PURPOSE:To make the restarted alarm sound louder successively from the initial small sound pressure level by resetting to the original conditions the memory circuit of alarm sound pressure level and so on through an alarm set switch. CONSTITUTION:Alarm sound generating circuits 5-7 are successively selected through D type flip flops FF1 and FF2 of which the state of memory changes successively by the output of a counter 10 after a specified time has elapsed, and alarm sound of which the sound pressure level becomes thereby louder by and by is generated as the time passes when the alarm time comes. Those flip flops FF1 and FF2 and the counter 10 are reset and return to their original position when an alarm select switch 9 is turned on. Accordingly if the alarm sound is stopped before the alarm sound does not reach the highest sound pressure, alarm sound which becomes louder from the lowest sound pressure is generated when the same alarm time arrives next day, for instance, if the switch 9 is operated.

Title: Quantum well structure having graded potential distribution and optical element formed by using this structure
Inventor: YAMADA ATSUSHI
IPC: G02F1/355
Filed: 1995-06-05
Abstract: PURPOSE: To make it possible to obtain a change in absorption intensity with a small electric field by controlling the presence positions of the electrons and holes in quantum wells by external electric fields. CONSTITUTION: This optical intensity modulator changes the intensity of the light emitted from a window 13 by changing the absorption coefficient of the light being made incident from this window 12 according to the intensity of the impressed voltage between electrodes 11 and 12. The stark effect to confine quanta is a phenomenon that the exciton absorption peak shifts to a low energy side when the electric field is applied perpendicularly to the quantum well structure in the structure. The shift quantity of the exciton absorption peak is larger as the intensity of the electric field is higher. Then, the overlap integral of the wave functions of the electrons and the holes is smaller than the overlap integral ofthe rectangular quantum well structure applied with the electric field of the same magnitude.  If the overlap integral diminishes, the electron-hole pairs by the light absorption of the quantum well structure are hardly formed and, therefore, the peak of the absorption intensity diminishes. The absorption intensity distribution is made broader by as much as the diminished component of the peak.
