Title: Production of magnetic disk
Inventor: TAKAHASHI ATSUSHI
IPC: G11B5/82
Filed: 1986-06-04
Abstract: PURPOSE:To enable uniform dispersion and to suppress the increase of medium noise by subjecting inorg. material powder to a surface treatment with a titanate coupling agent and using the same. CONSTITUTION:The titanate is used as the coupling agent and the coupling of a reinforcing material such as aluminum powder and binder resin is executed by using such agent, by which the uniform dispersion is attained. The reason for using the titanate coupling agent lies in that the titanate coupling agent exhibits an excellent effect to all inorg. material while a silane coupling agent exhibits an excellent coupling effect to silicon inorg. materials such as glass and silica (SiO2) but does not exhibit the good effect to the other materials.

Title: Image coder and image decoder
Inventor: KURIHARA KOICHI
IPC: H04N19/00
Filed: 1996-05-24
Abstract: PROBLEM TO BE SOLVED: To conduct coding processing by using a circuit with a comparatively low operating frequency and to reduce the coding and decoding circuit scale. SOLUTION: A received high definition TV (HDTV) signal is divided into horizontal low and high frequencies by a horizontal low pass filter(LPF) 72 and a subtractor 73. Furthermore, vertical low pass filters(V-LPF) 77, 78 and subtractors 79, 80 divide the HDTV signal into vertical low and high frequencies. Moreover, f conversion circuits 72, 81, 82 shift the frequency band of the image signal divided into each split band to lower frequencies so as to attain down- sampling. sample rate converters(SRCs) 74, 76 and SRCs 83, 86 reduce a sampling rate. Outputs of the SRC 83-86 are coded by coding circuits ENC 87-90. Since the sampling rate is reduced, coding is attained by using the ENC 87-90 corresponding to standard definition TV(SDTV), for example.

Filed: 1983-07-16
Abstract: PURPOSE:To simplify the constitution by supplying an alternate signal current and an alternate bias current to an alternate pulse current generating circuit in a multiplier circuit using a Josephson junction circuit. CONSTITUTION:The alternate signal current A1 supplied to an alternate signal current input line 12 and the alternate bias current B applied to an alternate bias current input line 13 are applied to the alternate pulse current generating circuit U1.

Filed: 1981-08-20
Abstract: PURPOSE:To decrease number of connecting points with a wiring board and to simplify the wiring board, by converging the number of terminals for the entire element while keeping the pattern in storage area unit split into a plurality as the same. CONSTITUTION:Power supply wirings 211 and 231 of read gate replicators 21 and 23 respectively at odd and even sides, and a bonding terminal 101 are connected to a common line b5 via conductor wirings 11-13 of contact holes c1- c6, and return wirings 212 and 232 and a bonding terminal 102 are connected to a common line b6 via conductor wirings 14-16 of contact holes c7-c12. Thus, four electrode lines of the two replicator gates at the odd and even sides can be converged to only a pair of the power supply wiring 101 and the return wiring 102 at the bonding terminals. As a result, the replicator gates in the element are connected in parallel with two-split to decrease the driving voltage, and conductor wirings are unnecessary for unnecessary connections of generator 31 and 32 and detectors 41 and 42 at the odd side, and this can also be applied to the even side.

Title: Manufacture of electrode catalyst for fuel cell
Inventor: ENOMOTO HIROBUMI
IPC: H01M4/88
Filed: 1984-06-25
Abstract: PURPOSE:To manufacture a gas diffusion electrode catalyst using a centrifuge to separate carbon particles having the same diameter as fluorine resin particles from among carbon particles dispersed in a solution and then causing a noble metal to be held by these carbon particles before they are mixed with the fluorine resin particles. CONSTITUTION:A matrix holding an electrolyte is interposed between an air electrode and a hydrogen electrode. Each of these electrodes consists of an electrode base (A) made of porous carbon and having gas flow paths (C), and a catalyst layer (B) formed by adding a fluorine resin to a carbon powder carrying a noble metal. The catalyst layer (B) is formed by causing the noble metal to be carried on carbon particles with almost the same diameter as fluorine resin particles, which are centrifugally separated from among carbon particles dispersed in a solution, before the fluorine resin is added to produce water repellency and then applying the thus prepared mixture to the electrode base (A) by screen printing or similar method. Consequently, localization of the fluorine resin is prevented and therefore high catalytic activity is achieved, thereby improving the characteristics of the fuel cell.

Two end plates 28, 29 are provided which have such a length as they can locate the dividing part between an arbitrary pair of cylinders without changing the distance between cylinders. It is thus possible to divide the exhaust receiver at the optimal location reducing the oscillation of the receiver.

Title: Adaptive equalizer
Inventor: NAKAI TOSHIHISA
IPC: H03H21/00
Filed: 1990-05-21
Abstract: PURPOSE:To enable equalization processing for a high-speed signal even when the calculation of each coefficient updating part is carried out at low speed by providing the plural coefficient updating parts and switching those outputs by a switching means. CONSTITUTION:After a signal from a transmission line is modulated, it is converted to a received signal y(n) being a discrete time signal by an A/D converter, afterwards inputted to an input terminal 11. On the other hand, a frequency divider 22 divides the frequency of a timing signal CLK inputted from an input terminal 12 and according to a select signal S22 as the result of the frequency division, respective selectors 21a and 19 are controlled to be switched in a selector part 21. Based on the select signal S22, the selector 19 supplies an error signal e(L) to be outputted from a subtracter 18 while switching it to first and second coefficient updating parts 20-1 and 20-2. By using a received signal y(L) inputted from the input terminal 11 and the error signal e(L) to be outputted from the selector 19, the coefficient updating parts 20-1 and 20-2 alternately execute algorythm for updating coefficients. Thus, even when the calculation is carried out at low speed in the coefficient updating part, the high-speed signal can be equalized.
