Title: Pressure developing device
Inventor: AKAO MICHITOSHI
IPC: G03D13/00
Filed: 1990-05-14
Abstract: PURPOSE:To eliminate fear that a work roller is stained by restoring an eccentric cam to an origin in a direction where a gap between a pair of work rollers is always opened from whatever state the eccentric cam is restored to the position of the origin. CONSTITUTION:This device is provided with a cam driving means 12 for normally and reversely rotating the eccentric cam 11 of a pressurizing force generation means, a cam position detecting means 13 for detecting the rotating position of the cam 11, and an origin restoration control means 14 for rotating and restoring the cam 11 to the position of the origin. The level of a detection signal is inverted at the position of the origin and a closing position of the rotation range of 180 deg. of the cam 11, and the means 13 confirms what range of the rotational angle the cam 11 exists in. By judging the position of the cam 11, it is known that the normal or reverse rotating direction where the cam 11 is rotated to the position of the origin without making the cam 11 at the closing position. Whatever position the cam 11 exists at, the eccentric cam is restored to the origin in the direction where the gap between a pair of work rollers 9 and 10 is always opened. Thus, the work rollers 9 and 10 are prevented from being stained at the time of controlling the pressurizing force.

Title: Signal processor for magnetic encoder
Inventor: HASEGAWA HIDENORI
IPC: G01D5/245
Filed: 1991-04-25
Abstract: PURPOSE:To enhance resolution by applying an AC voltage to magnetic sensors for A and B phases and subjecting the output from an encoder to amplitude modulation and then determining the displacement from the amplitude ratio of signals detected synchronously through AC coupling thereby eliminating the influence of fluctuation or offset of the encoder output while sustaining high response performance. CONSTITUTION:Magnetic sensors 10, 11 for phases A and B having phase difference of 90 deg. are connected in parallel and an AC voltage (sine wave signal) is applied from an oscillator 1 in order to amplitude modulate the encoder output. The outputs are subjected to AC coupling through AC couplings 12, 13 thus removing the offset component. The AC signal is subjected to synchronous detection with a (carrier) signal from a transmitter 1 by means of synchronous detectors 14, 15 to produce sine wave signals Va, Vb, which are then subjected to division 16 and a displacement is operated 17 based on the ratio Va/Vb. Since the magnetic sensors 10, 11 are disposed closely each other, fluctuation in the vibration of the rotary drum of encoder due to vibration of shaft has equal effect on the sensors 10, 11 and thereby has no effect on the detection of displacement.

Title: Manufacture of substrate for integrated circuit
Inventor: SATOU AKINOBU
IPC: H01L21/76
Filed: 1982-07-19
Abstract: PURPOSE:To obtain a substrate for an integrated circuit due to dielectric insulation isolation of high reliability and excellent characteristics by small number of processes by a method wherein isolation regions are formed by partially oxidizing a single crystal Si substrate, and oxidation is performed after this oxidized region is so etched previously as not to rise on the substrate surface. CONSTITUTION:An Si nitride film 13 is formed on the surface of the single crystal Si substrate 10, and, when the single crystal Si substrate 10 is anodically formed in hydrogen fluoride in the state that recesses are formed by etching exposed parts, the single crystal Si substrate 10 at the part wherein the surface is exposed is changed into porous Si. Since the Si changed porous is liable to be oxidized, the oxidation of the single crystal Si substrate 10 changes the former Si into Si oxides 14. The Si oxides 14 are formed, at the parts wherein porous Si is formed, with approximately the same areas. They grow up to surfaces approximately the same as the substrate surface at the time of finish of oxidation because of the formation of recesses on the surface previously. Thus, the single crystal Si 10 is so constructed as to be surrounded by the Si oxide 14 and the oxide film 11.
