Abstract: PURPOSE:To make an image within a necessary range clear and to surely inspect the pin of an IC by restricting lighting from a direction which crosses the optical axis of a camera within the nearly same flat surface of a substance to be inspected between a lighting device and the substance to be inspected. CONSTITUTION:Lead pins Is and Il extending from the respective short and long sides of the flat package IC 1 being rectangular in shape are set as the substances to be inspected. They are irradiated from the oblique lower part of the optical axis of the camera 6 extending from a flat mirror 5 to the IC 1 by the lighting source 4 arranged below a stage 2. Then, in order to improve the resolution of the image, the stage supports the IC 1 and rotates 90 deg. by 90 deg. from a prescribed position after the part of the IC 1 is image-picked up in several times by the camera 6 while the IC 1 is moved in linear movement by the stage. As the result of that, the pins Is and Il at all sides are image- picked up by the camera 6. Besides, the camera 6 and a shutter 3 placed at the lower part of the IC 1 are interlocked by a driving part 8 and moved according to the side which is image-picked up. Then, they are adjusted. Only the tip parts of the pins Is and Il are lighted by the shutter 3.

CONSTITUTION:The output signal of a second reference-wave signal generator 23 is represented by an inverter-side U-phase PWM reference wave 101 and an inverter-side PWM reference wave 102. The output signal of a carrier-wave generator 31 compares a PWM carrier wave 103 and the inverter-side U-phase PWM reference wave 101, and an inverter-side U-phase false sine wave 104, in which the inverter-side V-phase PWM reference wave 101 is at an 'H' level during a period when the level of the PWM carrier wave 101 is made larger than the PWM carrier wave 103, and is at an 'L' level during a period except said period, is output. The false sine signals are produced by the inverter-side U-phase PWM reference wave 102 and the PWM carrier wave 103. Accordingly, the external shape of an inverter device can be scaled down.

Inventor: KATO TAKAO
IPC: C30B31/00
Filed: 1985-09-30
Abstract: PURPOSE:To stabilize taking out of ions even in case of highly reactive metal by employing polycrystal material produced through gas phase growth or single crystal boron nitride for a needle anode in a liquid metal ion source. CONSTITUTION:A liquid metal ion source comprises a reservoir 4 made of low reaction material such as carbon for holding an ionizing metal under fused condition, a heater 3, a needle anode 7 and an ion take-out electrode 10.
