Title: Exposure method using charged particle beam
Inventor: HATTA JUNKO
IPC: H01L21/027
Filed: 1992-02-26
Abstract: PURPOSE:To enable image sensing of the whole band at a high speed, by a method wherein, when the image sensing start position of each band is not in the region which can be sensed by a charged particle beam, the image sensing start times of bands subsequent to the above band are delayed. CONSTITUTION:In a step S1, a CPU reads data like the number of subfields of each band. In a step 2, time necessary for the image sensing of each band is calculated on the basis of the read data. In a step S3, the image sensing end position and the image sensing end time of each band are obtained. In a step 4, the initial value of stage moving speed is obtained. In a step 5, whether the image sensing start position of an i-th band which is now noticed is in the region where image sensing is possible is discriminated. When the image sensing start position exceeds the region where image sensing is possible, sequence is branched to a step 6. In the step 6, the image sensing start time is so changed that the image sensing start of the band is delayed until the image sensing start position of said band reaches the region where image sensing is possible. In a step S7, the above delay is added to the image sensing end time, and modification is completed.

Title: Bipolar logic circuit
Inventor: KITORA KOJI
IPC: H03K17/66
Filed: 1988-02-23
Abstract: PURPOSE:To prevent the delay of tPLH(propagation time of change in output from L to H) even with application of noise to an output terminal by providing a 5th transistor(TR) whose emitter is connected to the output terminal and whose collector is connected to a high potential power terminal and connecting a current control circuit to the base of the said TR. CONSTITUTION:With a noise whose level is below -0.2V applied to an output terminal 4, a current control circuit supplies a base current to a Schottky barrier diode(SBD) npn TR 10 from a high potential power supply 1 through an emitter of a SBD npn TR 11. As a result, the SBD npn TR 10 is conductive to give a current to the output terminal 4 through the SBD npn TR 10 through the high potential power supply 1, then the output load capacitance is charged suddenly. Thus, a path from the emitter of a SBD npn TR 5 through a clamp SBD of the SBD npn TR 6 is lost and the SBD npn TR 5 is nonconductive, then the delay in the tPLH is prevented.

Title: Current limiter of dc motor
Inventor: NOMURA HIROYUKI
IPC: H02P7/298
Filed: 1984-03-05
Abstract: PURPOSE:To early set a target speed of a DC motor by enhancing the current limit value in a field control range at a starting time larger than the current limit value at the normal operation time. CONSTITUTION:A field current if is held in all field during periods t0-t1, and the shortcircuit of a starting resistor 8 is controlled so that the peak value Iap of the starting current becomes an overcurrent value Iacc or lower. When a resistance start finish signal (e) obtained from a controller of the resistor 8 and a speed command signal (f) from an instructing unit 11 are input to a converter 23, a limit value setter 25 sets the current limit value IL to IL2. When reaching the target speed n*, it decreases the value IL from the IL2 to IL1, and the operation is then continued with the current limit value as the LL1. Thus, the field accelerating times t1-t2 are shortened, and the setting time to the target value is shortened.
