Title: Digital filter and arithmetic circuit
Inventor: NOZAWA NAOYA
IPC: G10H1/02
Filed: 1993-04-01
Abstract: PURPOSE:To improve arithmetic efficiency. CONSTITUTION:Filter coefficient data are supplied from a register 74 for coefficient through an all bit inverter 76, which outputs input data as they are by supplying an inversion OFF control signal, and a selector 78 to a register 80. Data from a data memory 64 are supplied to a register 66, the data of the registers 66 and 80 are multiplied by a multiplier 68 and outputted. When an inversion ON control signal is supplied, all the bits of inputted data are inverted and supplied to the register 80 by the all bit inverter 76. When the coefficient data of the register 74 for coefficient are inverted by the all bit inverter 76, the result is approximated to a value multiplying -1.0 to coefficient data, and this is stored in the register 80. This value approximated to the value multiplying -1.0 to coefficient data is multiplied with the data of the register 66 by the multiplier 68.

Abstract: PURPOSE:To obtain a flexible raw fabric for pile fabrics without elution of a fixing agent in dyeing, by vertically setting pile yarns of a substrate sheet and adhering the base part thereof with the fixing agent consisting of styrene butadiene rubber and a specific thermosetting resin. CONSTITUTION:Piles 2, such as nylon, are vertically set in a substrate sheet 1 consisting of jute or synthetic fiber and a fixing agent 4 consisting of 80wt.% styrene butadiene rubber and 20wt.% aqueous chemical reactive type thermosetting resin (e.g., melamine resin) is continuously applied to the base part thereof, dried, then piece dyed and forcibly dried on a belt stretched parallel (the raw fabric is restored to a plane form at this time). The raw fabric restored to the plane form is then punched to a prescribed shape and a back side layer 5, such as natural rubber, is subsequently formed on the back side thereof to afford the aimed raw fabric for pile fabrics. Since the elution of the above- mentioned rubber in dyeing is suppressed with strong adhesion and accurate punching can be carried out in a state restored to the plane form by blending the afore-mentioned thermosetting resin as opposed to a conventional method, the accurate product is obtained.

Title: Mis type semiconductor device
Inventor: MIYAMOTO MASABUMI
IPC: H01L29/49
Filed: 1994-05-17
Abstract: PURPOSE:To provide a low voltage operating MIS type semiconductor device wherein low threshold level is realized by sufficiently reducing a subthreshold coefficient when the device size is very minlaturized, and mobility can be improved by reducing electric field strength on the gate insulating film interface. CONSTITUTION:An N layer 6 of the same conductivity type as a sorce/drain is formed between a P<-> low concentration layer 5 in a channel region and a P<+> high concentration buried layer 7. The thickness of the N layer 6 is set so as to be turned into the depletion state by a PN junction formed between an upper P layer 5 and a lower P layer 7. Thereby the N layer 6 acts so as to stretch a depletion layer, which is spread from an inversion layer formed by applying a gate voltage, as far as the upper surface of the P<+> high concentration buried layer 7. Hence depletion layer capacitance is reduced, and electric field strength is lowered.

Filed: 1984-05-21
Abstract: PURPOSE:To perform an error sampling by the same circuit even in any rotating direction by performing twice error sampling for one period of a FG signal obtained by detecting a motor rotation, thereby improving the high pass characteristic of a servo loop. CONSTITUTION:A gate pulse generator 10 is provided to independently sample- hold errors before and after 90 deg. between zero crosses of rises and falls of the first and second FG signals having substantially sinusoidal waveshapes of 90 deg. of phase difference detected by a magnetic sensitive head 4, and then add by an adder 21. Thus, even if irregular zero cross detection occurs, it can be eliminated by averaging the error difference before and after 90 deg.. This corresponds to double the apparent error sampling number without altering the number of teeth of the rotation detecting FG and the frequency of the FG signal, thereby largely improving the responding characteristics of a servo loop.
