Title: Driving circuit for commutatorless dc motor
Inventor: ITOU JINICHI
IPC: H02P6/08
Filed: 1980-05-16
Abstract: PURPOSE:To obtain a commutatorless motor having no torque ripple by producing only a voltage responsive to a magnetic pole with a differential amplifier forming a voltage follower from the output of a Hall element for detecting the variation in the magnetic pole of a rotor. CONSTITUTION:A rotor magnetic pole position detecting voltage outputted from a  Hall element 4 is inputted to differential amplifiers 6, 8 forming a voltage follower.  Since the potential of an output terminal 8b is, when the detected voltage is generated at the output terminal 4d, high at the output terminals of the differential amplifiers 6, 8, transistors 7b, 9b are conducted ON. Thus, a current I0 will flow  through a current amplifier 11 to a transistor 9a, resistors R4, R3, R2, and transistors 7b, 12. Since the terminals A, B of the resistor R3 are connected to the amplifiers 6, 8, the current I0 which flows through the resistor R3 will become the differential voltage between the output terminals of the Hall element 4 and hence the  sinusoidal waveform current proportional to the variation in the detected magnetic  flux.

Title: Negative type resist for double-layered structure
Inventor: YONEDA YASUHIRO
IPC: H01L21/027
Filed: 1987-03-20
Abstract: PURPOSE:To make it possible to form a fine pattern even on a substrate having large difference in level by using a compsn. consisting of a silicon modified alkali-soluble resin, partial ladder type silicone resin and an azido or bisazido compd. to form a resist layer. CONSTITUTION:An org. resin layer 2 is formed on a substrate 1 by coating. A photoresist layer 3 consisting of a silicon modified alkali-soluble resin, partial ladder type silicone resin and an azido or bisazido compd. is formed on the layer 2 by coating, patternwise exposed to UV and developed with an alkaline developing soln. The org. resin layer 2 is then etched with oxygen plasma. The resist compsn. has high resolution and also has improved resistance to oxygen plasma because of the partial ladder type silicone resin, so side etching during the etching of the layer 2 is suppressed. By using the negative type resist, a fine pattern can be formed even when the substrate 1 has large difference in level. The resist is used to produce an electronic circuit device having a fine pattern such as a semiconductor device, a magnetic bubble memory device or a surface wave filter.

Title: System for detecting reproduced data
Inventor: ITOI TETSUSHI
IPC: H03M13/00
Filed: 1991-03-28
Abstract: PURPOSE:To reduce error-rate by limiting input levels at reproduced state in specified numbers, after converting the reproduced signals to binary and discriminating the levels, and detecting input states against the rules of state transition. CONSTITUTION:The reproducing states are four states of S0-S3, when -1 is inputted at the state S0, the state is S0 and output data is 0, and when 1 is inputted at S0, the state is changed to S1 and output data is 1. Then, when 1 is inputted at S1, the state is changed to S2 and output is 1, and when -1 is inputted at S2, the state is changed to S3 and output is 0, and when 1 is inputted at S2, the state is S2 and output is 1. Also, when -1 is inputted at S3, the state is changed to S0 and output is 0. Thus, when input against the those rules of the state transition comes, by detecting the against state, discriminating the state of its own and correcting a bit-error, the error-rate to random- errors is reduced.
