Title: Pulse generator
Inventor: JIYON BERII RETEIGU
IPC: H03K17/04
Filed: 1989-09-05
Abstract: PURPOSE: To maintain the edge parameter of an output step pulse at an almost fixed value even when the value of a load resistor is changed by providing the pulse generator with 1st and 2nd high speed control means or the like and switching 1st and 2nd diode switches by respective high speed driving signals. CONSTITUTION: Capacitors C1, C2 constituting 1st and 2nd high speed control circuit respectively input high speed driving signals A, B to turn the ON/OFF of control terminals of 1st and 2nd diode switches CR1, CR3 and CR2, CR4 from a 1st state to a 2nd state. In this case, 1st and 2nd voltage driver resistors R1, R7 and R2, R8 maintain voltage between the input terminals of the switches CR1, CR3 and CR2, CR4 and the control terminals almost at the fixed value independently of the value of the load resistor 11. Namely even when one end of the resistor 11 is grounded, voltage between both ends of reversely biased diodes CR1, CR2 is maintained almost at the fixed value. Consequently the edge parameter of an output step pulse can be maintained almost at a fixed value.

Filed: 1999-08-17
Abstract: PROBLEM TO BE SOLVED: To obtain a charged particle beam exposure system, which has high linewidth controllability on an exposure object due to improvements in the resolution of an illumination optical system. SOLUTION: Charged particles emitted from a charged particle beam source having a two-dimensional array shape illuminate a mask 3 by forming spots arranged in a two-dimensional array shape. Patterns of fluorescent material are formed on the mask 3, and fluorescent lights are emitted by the application of the charged particles. The emitted lights are focused by a transfer optical system to form image on a photoelectric surface 5 as in a conventional constitution. A minute photoelectron emitting two-dimensional array is formed on the photoelectric surface 5 at a position which is conjugate with the position of the two dimensional spot array on the mask 3 and photoelectrons 6 are emitted from the photoelectron emitting two-dimensional array, on which light is focused.  The emitted electrons 6 form spots on an exposed object 7 by an optoelectronic system (not shown), such as a 1-1 image ficusing system using high magnetic field, etc., having desired resolution.

Abstract: PURPOSE:To eliminate a need for heating an ingot prior to hot rolling so as to economize heating fuel and to simplify a continuous casting and hot rolling stage by providing a pair of deformed casting molds which tightly adhere solidified shells intermittently to each other. CONSTITUTION:A molten steel is poured into a reference casting mold 3 and is cooled by which the solidified shells 11 are formed to the periphery. The ingot 10 in which an unsolidified steel 12 exists moves downward and is further cooled by the deformed casting molds 4. The molds 4 make the cyclic motion shown by arrows 7 and casting molds 5 on the long sides move in the direction where the walls move near to each other. As a result, projections 8 crush the easily deformable shells 11 at a high temp. to tightly adhere the shells 11 to each other. The walls 5 move downward by a prescribed distance even after the solidified shells are tightly adhered to each other. The walls are parted from the ingot 10 and move upward thereafter to return to the home positions. The parts 13 where the solidified shells are tightly adhered to each other are formed at prescribed intervals to the ingot 10 by such operation of the molds 4. The ingot is cut at the parts 13 upon arriving at the position of a cutter 9. The ingot after the cutting is conveyed to a hot rolling stage.

Title: Recording medium
Inventor: YAMAGAMI TAMOTSU
IPC: G11B7/007
Filed: 1991-09-11
Abstract: PURPOSE:To reproduce the recorded data of entire zones with a data detection by a ternary detection by setting the boundary part of each zone in the neighborhoods of parts where a reproducing state at the time of the data detection by the ternary detection is less than a prescribed value. CONSTITUTION:Plural concentric-circular tracks are prepared on one magneto- optical disk, and divided into zones A and B. Then, the data recording density of the most inner peripheral track of each zone is made equal. At that time, as for the data recording density of the innermost peripheral track of each zone, when the phase margin is more than a constant value at the time of detecting the recorded data by the ternary detection of a partial response(PR) class 1, the phase margins of the innermost peripheral and outermost peripheral tracks of each zone are the worst, and the phase margin of the intermediate part track of each zone is the best. Then, the value of the worst phase margin is turned to be the value by which the normal data reproduction can be attained. However, at the time of the data detection by the ternary detection of the PR class 1, the change of the phase margin is moderate, and actually the changing amount of the phase margin due to the difference of the track is reduced.

Title: Control method of meandering
Inventor: MIYASAKA KIYOTO
IPC: B21B37/68
Filed: 1982-12-23
Abstract: PURPOSE:To control the distribution of tension of a sheet at the inlet side for preventing the meandering of sheet, by imposing a tension on the sheet end of the meandering direction of the sheet which is running while being wrapped around either an upper roll or a lower one, in a wrapping type rolling. CONSTITUTION:A dancer roll 4 whose both ends are made independently movable in the vertical direction is provided to the sheet 3 inlet side of a work roll 1 rotating at a high speed and a lower work roll 2 rotating at a lower speed than the roll 1. The sheet 3 at the inlet side is wrapped around the lower side of the roll 4 locating under rolls 5, 5 without being wrapped around the roll 2, and is inserted into a gap 6 between the rolls 1, 2 and wrapped successively around the roll 1 thereby the sheet 3 is rolled. When the generation of the meandering of sheet 3 is detected at the inlet side, the sheet drawing speed at the meander- generating side is decreased by tilting the roll 4 to raise the sheet tension at said side. Thus the meandering of sheet is prevented and a rolled sheet having excellent shape is obtained.

Title: Motor driving equipment
Inventor: OKUMURA TAKEKIYO
IPC: H02P7/291
Filed: 1996-09-03
Abstract: PROBLEM TO BE SOLVED: To surely reduce a coil current during current OFF command term. SOLUTION: This motor driving equipment supplies a desired coil current to a motor coil, by pulse-width-controlling either one of motor driving transistors of a power supply side and a ground side. In OFF command term in which a coil current is reduced and during OFF term of the motor driving transistors, both the transistors of the power supply side and the ground side are subjected to OFF control, both sides driving is performed from when the OFF term is started to when the level of coil current is decreased to a specified level, and a coil current is rapidly reduced. A second comparator compares the level of a coil current, e.g. a CR output waveform corresponding to the coil current level with a specified switching level V2, and generates a switching detecting signal when the CR output waveform becomes equal to or lower than V2.  Thereby transfer is performed to single side driving in which either one of the motor driving transistors of the power supply side and the ground side is subjected to OFF control, and the coil current is gently reduced.
