Abstract: PURPOSE:To connect pad electrodes therebetween only with an IC chip of a standard product without adding any special processing by forming beforehand a gold ball electrode on at least one of the two electrodes to be wire bonded, and bonding a gold wire thereon. CONSTITUTION:A gold ball formed at the end of a gold wire is bonded on a pad electrode 4a by means of ultrasonic bonding having 20 of ultrasonic energy US power, 150 deg.C and 50g of applying weight, and a wire part is cut mechanically or by heat to form a gold ball electrode 4c. Then, a first bonding to the pad electrode 3a of an IC chip 3 is conducted by ultrasonic ball bonding under the same conditions as those of the first bonding to the electrode 3a of the chip 3, and a second bonding to the electrode 4a is conducted to connect the other end of a gold wire 6 to the electrode 4a formed on the electrode 4a by thermal press-bonding having 150 deg.C, 50g of applying weight and 0 or US power. Thus, the second bonding on the electrode 4c can prevent a shoulder touch from occurring by raising the extending position of the wire 6 by the height of the electrode.

IPC: B65D85/86
Filed: 1991-08-30
Abstract: PURPOSE:To provide a wafer keeper which does not generate sliding between it and a wafer and prevents contamination of a wafer by restraining generation of particles. CONSTITUTION:Each elastic piece 6 of a wafer keeper 3 is constituted bendably using an intermediate point as a fulcrum while keeping a contact part with a wafer immovable. Therefore, even if a wafer contained in a wafer container vibrates during transportation, the elastic piece 6 of the wafer keeper 3 bends using an intermediate point (bending point) as a fulcrum while stopping the wafer and absorbs vibration of the wafer; therefore, sliding is not generated between the elastic piece 6 and the wafer. As a result, the elastic piece 6 is not ground and particles are not generated, and the wafer can be surely prevented from being contaminated by particles. Furthermore, the wafer keeper 3 carries out its original function to hold the wafer elastically and to prevent damage thereof.

Title: Howling-removing device for speaker
Inventor: MIMURA SHUICHI
IPC: H04R3/00
Filed: 1996-08-13
Abstract: PROBLEM TO BE SOLVED: To automatically detect and remove howling by amplifying an inputted voice, forcedly generating howling, detecting a frequency and attenuating it by an adaptive filter so as to extend the limit of the sound volume of a speaker. SOLUTION: The inputted voice from a microphone is amplified to a voice processable level by means of a microphone amplifier 1, serially connecting operational amplifiers A1 and A2 to forcedly generate howling. Next, a howling frequency is detected by a filter amplifier with a detection circuit 2, incorporating the notch filter of an attenuating characteristic obtained by dividing an audible frequency band into nine parts by each octave. In addition, a notch filter for attenuating this howling frequency band is selected. A buffer amplifier 3 corrects the sound volume before and after detecting howling, by means of an amplifier with the amplitude switch of the operational amplifier A5 to ultimately attenuate to a microphone inputting level. Thereby the limit for the sound volume of the speaker is magnified to automatically detect and remove howling.
