Title: Linear resolver
Inventor: NAGASAKA NAGAHIKO
IPC: H02K24/00
Filed: 1985-02-15
Abstract: PURPOSE:To realize a magnetic sensor and a linear scale by a common means, by constituting a stator from a magnetic body having teeth formed thereto at equal pitches by cutting and supporting a movable element so as to provide definite gaps from an electromagnetic, wherein primary AC winding is applied to E-shaped and C-shaped cores, and the stator wherein secondary winding is adhered to the cross-section of a magnetic path. CONSTITUTION:When primary winding W0 is excited by monophase AC, mag netic flux phi is generated. Secondary winding WALPHA, WBETA are wound at a coil pitch 1/2 the tooth pitch of a stator so as to intersect the magnetic flux phiand arranged at positions mutually having phase difference of 90 deg. as an electric angle. The winding WBETA and the winding WBETA can be constituted of a comb shaped printed conductor. Therefore, when a movable element 2 moves, the induced voltages of the windings WALPHA, WBETA generate a sine wave like change of a wavelength corresponding to the tooth pitch of the stator and, because the phase difference between the induced voltages of the secondary windings WALPHA, WBETA is 90 deg., the function as a resolver is obtained.

Title: Driving method for ferroelectric liquid crystal element
Inventor: KAWAGISHI HIDEYUKI
IPC: G09G3/36
Filed: 1988-02-10
Abstract: PURPOSE:To prevent a noise from being superposed on a write signal by shifting AC signals of adjacent scanning lines in one or plural groups in phase from one another. CONSTITUTION:The AC signals of adjacent scanning lines Sn and Sn+1 are made opposite in phase. Consequently, the electric field directions of signals voltages in phase become opposite in phase, so the voltage difference between electrodes is canceled. Therefore, the voltage in the same directions are not induced, noises are prevented from being superposed on write signals IW and IB, and malfunction and a decrease in driving margin are eliminated. The contrast is improved and a stable display is made by AC-stabilizing driving as mentioned above.

Title: Method for correcting aberation of electron-beam exposing apparatus
Inventor: MIYAZAKI TAKAYUKI
IPC: H01J37/153
Filed: 1979-03-12
Abstract: PURPOSE:To correct the aberation of an electron beam by secondary electrons, by scanning particles by the electron beam in the direction from the lagest-diameter particles to the smallest on a target on which fine-particle specimens are arranged on specified positions on the order of the sizes of the diameters of the particles. CONSTITUTION:Fine particles of tungsten oxide are arranged on an Si plate 1. They are divided on the regions A-E on the order corresponding to the sizes of the diameters of the particles, so that the particles having the largetst diameter are assigned to the region A, and the particles having the smallest to the region E. The particles are stuck and fixed by an adhesive agent. An electron beam is projected to the region A, and secondary electrons are received by a photoelectric-multiplier tube, and displayed on a CRT. The blurred focusing is corrected by the coil current of a projection lens, and astigmatism is corrected by the coil current of a four- layer electrode lens. Then, the region B is scanned by the electron beam, and the focus and the astigmatism are likewise corrected. Then, the correction is made more finely in the sequential order, and the highly accurate beam image can be formed on the surface of the body under treatment.

Title: Booster type dc/dc converter
Inventor: NAKAMURA MANTARO
IPC: H02M3/155
Filed: 1994-02-25
Abstract: PURPOSE:To reduce power loss, i.e., switching loss, of a switching element at the time of ON/OFF operation thereof by constituting a DC/DC converter such that zero voltage or zero current switching is achieved for the switching element thereby decreasing the overlapped part of voltage waveform and current waveform of the switching element. CONSTITUTION:When a main transistor (Tr) 2 feeding a current to a boosting reactor 4 and charging a resonance capacitor (C) 8 with the terminal voltage of a load 6 is turned OFF, current flow is deflected from the Tr2 to the C8 which is gradually discharged. Consequently, the voltage across the Tr2 increases gradually from 0V thus achieving zero voltage switching of the Tr2 at the time of turn OFF. When an auxiliary transistor Tr9 is turned ON prior to turn ON of the Tr2, current flowing through a resonance reactor 10 during the conduction interval of a main circulation diode 3 increases from zero thus achieving zero current switching of the Tr9 at the time of turn ON.

Abstract: PURPOSE:To obtain an FET which improves a gate withstanding voltage by forming N<+> type layers for source/drain by twice with respect to a gate elec trode in a self-alignment. CONSTITUTION:An N-type active layer 2 is formed by ion implanting on a semi-insulating GaAs substrate 1, and a gate electrode 3 of refractory metal such as TiW is formed. It is covered with a CVD-SiO2 film 4A of approx. 150Angstrom  thick, and ion implanted to form N<+> type source/drain layer 5A. It is again covered with a CVD-SiO2 film 4B, films 4B, 4A are allowed to remain on the side of the electrode 3 by RIE, and ion implanted to form an N<+> type layer 5B on the electrode 3 in a self-alignment. Source/drain electrodes are attached by heat treating to complete a transistor. Since the impurity density of the layer 5A is lower than that of the layer 5B, a gate withstanding voltage is improved.

Title: Roller leveler and driving apparatus for said roller leveler
Inventor: ONO YUKIO
IPC: B21D1/05
Filed: 1986-02-12
Abstract: PURPOSE:To prevent generating a sliding flaw of a plate material and breaking rolls by driving each leveling roll independently with respective prime movers synchronizing a peripheral speed of a contact surface of the plate material with the leveling roll. CONSTITUTION:Each leveling roll is respectively connected to universal shafts 3. Then the shafts 3 are engaged with large diameter gears on a pinion stand 4 to connect with each electric motor 9 through pinions 6 corresponding to the number of shafts 3. At leveling the plate material P, the plate material P is passed between the upper and lower rolls to give the plastic bending of a prescribed radius of curvature to level a flatness of the plate. In this case, the peripheral speed of the contacting part of the roll 1 with the plate material P is synchronized to the progressive speed of the contacting surface of the plate material P with the roll 1. In this way, the sliding between the plate material P and the roll 1 is not occurred and no flaw is generated on he surface of the plate material P. Furthermore, as each roll 1 is independently driven respectively, and each electric motor 9 has only the driving capacity for its roll 1 to stop at over setting, so the shaft 3 is not broken.

Filed: 1987-02-10
Abstract: PURPOSE:To dispense with setting pulse numbers per revolution of an incremental rotary encoder, by providing a counter circuit to measure the number of pulse of the incremental encoder per revolution. CONSTITUTION:A CPU 10 discriminates the number of pulse per revolution of an incremental rotary encoder 4 through the value of the second counter circuit 15.

Further, the current command value is operated from the rotor position of a synchronous motor 1 from an absolute rotary encoder 4 and the speed deviation value. Then, the pulse width modulation output signal is operated by the current value from an A/D counter 8 and the current command value.
