Title: Speaker
Inventor: SHIMADA KOUSHIN
IPC: H04R9/06
Filed: 1980-03-19
Abstract: PURPOSE:To obtain a speaker that efficiency is good in all bands, by providing two sets of voice coils. CONSTITUTION:Voice coil bubbines 4 and 6 provided with voice coils are arranged in magnetic gaps different in gap width and are connected to diaphragm 9 through the adapter and so on.

Title: Near ultraviolet-visible-near infrared fourier spectral apparatus
Inventor: INOUE KATSU
IPC: G01J3/45
Filed: 1988-02-19
Abstract: PURPOSE:To obtain a high sensitivity near infrared spectral apparatus, by using an image intensifier:II immediately before a unidimensional photodiode array. CONSTITUTION:When accelerated voltage is applied to a multichannel plate 65 from a high voltage power supply 67, the photoelectron flown out by an interference fringe 59 is multiplied corresponding to the applied voltage to excite a fluorescent surface 68 and an intensified interference fringe image is outputted. This output image is detected by a unidimensional diode array 70. The photodiode array 70 performs self-scanning and an image current signal 74 is converted to a digital signal 84 by an A/D converter 80 through an amplifier 75 to be inputted to an arithmetic memory unit 100. Next, change-over is performed in the direction shown by an arrow 48 by the output and control interface 90 connected to the apparatus 100. By this method, since the polarity of the light and shade of the interference fringe 95 is reversed, an interference signal can be differentially taken in. By this constitution, the interference figure stored in the apparatus 100 is subjected to Fourier transform to become a spectrum figure which is, in turn, taken out from signal output 98.

Filed: 1983-03-04
Abstract: PURPOSE:To extract a color signal with high quality, by using a scanning line of adjacent field of a composite color television signal, separating the color signal and reducing a residual color signal to a luminance signal. CONSTITUTION:An NTSC signal inputted to a terminal 1 is inputted to a delay circuit 2 where the signal is delayed by 263H (where H is a horizontal scanning period), and a difference with the signal delayed by 263H is obtained at a subtraction circuit 3. Since the phase of a subcarrier is inverted for a present scanning line and the signal delayed by 263H, the signal having the amplitude double the chrominance carrier signal is obtained as an output of the circuit 3. This is multiplied by 1/2 at a multiplication circuit 4, a band taking the subcarrier frequency as a center is extracted at a BPF 5, then a desired chrominance carrier signal (signal C) is obtained at an output terminal 8. In subtracting this signal from the present signal (NTSC signal) at a subtraction circuit 6, a luminance signal (Y signal) is obtained at an output terminal 7.

Abstract: PURPOSE:To prevent soft errors due to the irradiation of alpha rays by a method wherein the drain region used as a bit line is formd by using the silicon semiconductor layer on an oxide film so that the contact area between the drain region and the semiconductor substrate is made exceedingly small. CONSTITUTION:A thin oxide film formed on a semiconductor substrate 11 is selectively oxidized to form a thick oxide film 15 on the whole except for the portion where a memory capacitor is to be formed. Then, patterning is performed to leave the thick oxide film at the portion where a drain region is to be formed, and monocrystalline and polycrystaline Si layers 17P and 17S are grown. After said processes, n<+> type source regions 22S and 22ST, a drain region D and a drain region 22T to be a bit line are formed by the ion implantation. Accordingly, there is no portion cutting into the substrate 11. In addition, the contact area between the drain region and the substrate 11 becomes exceedingly small, so that the stretch of the depletion layer is made small. Thereby, the resistance to alpha rays is improved, and soft errors can be prevented.
