Title: Speaker device mounted on vehicle
Inventor: KAWAMURA AKIHISA
IPC: H04R3/04
Filed: 1984-09-07
Abstract: PURPOSE:To listen in a constantly good frequency characteristic independently a relation to conditions in a vehicle by measuring an acoustic place in the vehicle, comparing the frequency characteristics of an original signal with a measuring signal by means of a comparison means and controlling a correcting means for correcting the frequency characteristics by means of a control means. CONSTITUTION:Since to the frequency characteristic of an output signal from a sound receiving frequency characteristic correcting means 11, a correcting characteristic is added, the output signal does not receive the influence of the sound receiving frequency characteristic, and an acoustic characteristic in a vehicle only can be known from this output signal. In this way, a characteristic setting operation is completed. Then, in the case of regenerating an output signal from a sound source 2, at first, switches 10a, 10b are changed over to a B side, the signal from the sound source 2 is generated by the frequency characteristic set by the above-mentioned method. In this manner, one speaker is used for regenerating and as a sensor for detecting an acoustic place in the vehicle in common, the frequency characteristic is corrected according to the condition of the vehicle and thereby a constantly good acoustic characteristic for listening can be obtained without relating to the conditions in the vehicle.

Abstract: PURPOSE:To produce a fluorescent lamp whose efficiency is high and whose color of light and color rendition are approximate to those of natural light, by providing a fluorescent film in which a blue, a green and a red light emission fluorescent substances set at prescribed grain diameters respectively are blended at a prescribed ratio. CONSTITUTION:A fluorescent film, in which 10-18wt% of a blue light emission fluorescent substance having a grain diameter of 2.0-2.7mu and represented by a chemical formula 3(Ba,Mg)0.8Al2O3:Eu<2+>, 40-55wt% of a green light emission fluorescent substance having a grain diameter of 3.0-4.3mu and 45-35wt% of a red light emission fluorescent substance having a grain diameter of 3.7-4.5mu are blended, is provided to manufacture a fluorescent lamp. The grain diameter of the blue light emission fluorescent substance is made smaller than those of the other fluorescent substances to compensate for the fact that the light emission efficiency of the blue light emission fluorescent substance is lower than those of the other fluorescent substances. Besides, the weight percentage of the blue light emission fluorescent substance is made smaller than those of the other fluorescent substances to keep the color of light and color rendition of the lamp from deteriorating. As a result, the color of light and color rendition of the lamp are approximated to those of natural light and the light emission efficiency of the lamp is much enhanced.

Title: Semiconductor device
Inventor: SHIMIZU KOZO
IPC: H01L21/321
Filed: 1996-07-18
Abstract: PROBLEM TO BE SOLVED: To deter or stop the diffusion of Ni as a material of a substrate electrode film into a solder material by providing a metal layer which suppress the diffusion of Sn in an Ni film. SOLUTION: Substrate electrode films of a bump formed on a semiconductor chip or package are laminated in the order of Ti, Ni, Cv, Ni, and Au. In the laminated films, Ni on the solder side is diffused into Sn of the solder so that the Cr film 5 comes into direct contact with Sn. Here, Sn and Cr are low in wettability and form no metal oxide, so the reaction speed decreases. The Cr film 5, however, is thin and in the laminated state right after sputtering, but Ni 7 is diffused during transfer, a wet-back soldering process, etc., to move to a defect (gap in the Cr film 5 and form an island-shaped distribution, so that Ni 7 is gradually diffused together with Cr. Consequently, the diffusion speed of Ni 7 can be suppressed without spoiling joint strength.
