Title: Low vacuum atmosphere scanning electron microscope
Inventor: ITO MASUHIRO
IPC: H01J37/28
Filed: 1994-11-09
Abstract: PURPOSE: To provide a low vacuum atmosphere scanning electron microscope provided with an inexpensive and simple exhaust system consisting of only an oil dispersion pump and a rotary pump. CONSTITUTION: High vacuum in an electron gun part 3 irradiating an electron beam and low vacuum in a sample chamber 10 for arranging a sample 8 are so formed as to be simultaneously held by combining a network of flow path resistance. The sample chamber 10 communicates with atmosphere via a flow path resistance member 35 of flow path resistor R1 and the atmosphere is exhausted by a rotary pump 29 via an exhaust pipe 31 having flow path resistor R2. Resistors R1 and R2 are so set that its rate R2/R1 is a prescribed value in the range of 1/100-1/10000. A rotary pump which is conventionally used exclusively for exhaust of the sample chamber can be thus eliminated and cost of the whole exhaust system can be reduced.

Title: Double-needle sewing machine with single-needle halting device
Inventor: KOSAKU MINORU
IPC: D05B55/10
Filed: 1990-10-15
Abstract: PURPOSE:To perform a beautiful curved sewing without troublesome operation by providing a controller which releases a single-needle halting device every specified count number of stitches while a single stitch is made. CONSTITUTION:Two needles are brought in sewing action together to form the same number of stitches from the beginning up to the position A and after the position B. Between the positions A and B, the needle on the right forms lass number of stitches than the needle on the left does. In such curve sewing, the outside and inside curves usually consist of the same number of stitches of the left and right needles, however, the inside curve has less number of stitches than the outside curve, for example, four stitches for the outside curve against two stiches for the inside curve. Thus, the number of actions of a needle bar, which does not receive a halting instruction, against one action of the other needle bar which receives the halting instruction, and the number of repeating action are set by a stitch number setting device 4, and those signals are input to a central processor 9. A program is designed so that stitch omission and repeating action of the specified number are executed.

Abstract: PURPOSE:To bring an output high level to a power voltage level without causing latch up even when an abnormal noise is applied to the output by constituting the output circuit with the 1st conduction type 1st transistor (TR) whose source is connected to the 1st power supply, the 2nd conductor type 2nd-6th TRs whose sources are connected to the 2nd power supply, a delay circuit and a static capacitor. CONSTITUTION:When the level of an input terminal IN changes from a high level to a low level at a time t1, a TRQ3 is turned on, the 1st contact 1 goes to a high level, then the 3rd and 4th TRS Q5, Q7 are turned on and the 2nd contact 2 and an output terminal OUT go to a high level. However, the high level of the 2nd contact 2 is VCC-VTH and the high level of the output terminal OUT is VCC-2VTH, where VTH is a threshold voltage of TRs. A static capacitor C is charged during this time. When a contact 3 at the output terminal of a delay circuit 4 goes to a high level at a time t2, the high level of the 2nd contact 2 is boosted to a value VCC+VTH or over by the coupling of the capacitor C and the high level of the output terminal OUT goes to the VCC.
