Title: Signal processing circuit for encoder
Inventor: IIJIMA KENZABURO
IPC: H03M1/20
Filed: 1988-07-08
Abstract: PURPOSE:To markedly enhance resolving power by applying required analogue signal processing to the output of a sensor to divide said output and further applying predetermined digital processing thereto to finely divide the same. CONSTITUTION:The displacement of a magnetic scale 15 is read by magnetic sensors 16, 17 to output a sine signal sinalpha and a cosine signal cosalpha, and these signals are subjected to multiplying processing, squaring processing and subtraction processing by an analogue operation circuit 8 to be divided into sine and cosine signals sintheta, costheta of double em. The signals sintheta, costheta are multiplied by the cosine and sine signals costheta, sintheta from a function generating ROM 25 through A/D converters 18, 19 and the multiplied signals are further finely divided by a PLL formed from a subtractor 22, a comparator 23 and an incremental/decremental counter 24 to be counted by the counter 24. By this two-step division, resolving power is markedly enhanced.

Title: Silicon carbide composite material and its production
Inventor: YAMADA MASUZO
IPC: C23C16/458
Filed: 1995-07-06
Abstract: PROBLEM TO BE SOLVED: To obtain a composite material developing no atmospheric contamination even under high-temperature conditions, and suitable for e.g. the reaction tubes for semiconductor diffusion oven, by specifying the spectrum absorption end of silicon carbide film. SOLUTION: This composite material is made up of a basal body as a porous silicon carbide sintered compact produced by molding and sintering high-purity silicon carbide powder to a specified reaction tube shape and silicon carbide film(s) as β-SiC chemical vapor deposition film(s) on one or both of the circumferential surfaces of the basal body depending on e.g. the working conditions for the reaction tube. Since the content of heavy metal elements such as Fe, Cu and Cr in the silicon carbide film(s) is extremely low, wafer contamination due to evaporation of such impurities does not occur. Although there are some limitations in the film-forming conditions, it is so specified that the spectrum absorption end falls between 520 and 550nm.  This composite material is obtained by the following process: the basal body is placed in a CVD oven which is then depressurized to 0.1-200Torr and then fed with monomethyl trichlorosilane as reaction gas at 1400-1500 deg.C followed by continuous exhaustion to effect CVD so as to be 50-150μm in film thickness.

IPC: H04H1/00
Filed: 1983-09-16
Abstract: PURPOSE:To prevent noise from being outputted by inhibiting the output of a limiter circuit when the output of an intermediate frequency circuit is smaller than a predetermined level value. CONSTITUTION:A high frequency from a broadcast station received at an antenna 1 is fed to the limiter circuit via a high frequency circuit 2 and the intermediate frequency circuit 3.

Title: Head abutting mechanism for magnetic recording and reproducing device
Inventor: ANDO SHUJI
IPC: G11B17/32
Filed: 1985-08-07
Abstract: PURPOSE:To simplify a structure and make the size compact by sucking a magnetic disk to a magnetic head by a negative pressure generated in a gradation part during a high speed rotation of the magnetic disk. CONSTITUTION:When a floppy disk 2 is rotated at high speed in the direction shown by an arrow A, air in the vicinity of a surface of the floppy disk 2 flows in the same direction together therewith. However, since there is a stepped part 8b of a slider 8 at an upstream side of an air stream, the stepped part 8b becomes a weir and the flow is throttled. As a result, an upper surface of a gradation part 8a at a downstream side of the stepped part 8b has a negative pressure, the floppy disk 2 having flexibility is sucked to the gradation part 8a by this negative pressure and pressed to a magnetic head 7. This contact of the floppy disk 2 and the magnetic head 7 is maintained while the floppy disk 2 is rotated at high speed. Thereby, a pad for pressing a magnetic disk to the magnetic head can be omitted and the structure can be simplified and made compact.
