Title: Manufacture of lead frame
Inventor: KOBAYASHI TOSHIHIKO
IPC: H01L21/60
Filed: 1990-06-22
Abstract: PURPOSE:To remove hand coating, and to improve productivity by exclusively installing sprocket holes for positioning/carrying for manufacturing a lead frame and for mounting an IC respectively. CONSTITUTION:A wide raw material (a hoop material) is prepared, and sprocket holes 1, 2 at every two rows on both sides are bored through pressing working. The width 3 of the mutual internal sprocket holes is used as a standard for positioning/carrying in mounting, and the external sprocket holes are used for manufacturing a lead frame. Since the peripheries of the internal sprocket holes 1 are coated continuously when the external sprocket holes 2 are coated with a resist for carrying, the internal sprocket holes requires no second coating before etching. Since the external sprocket holes 2 are unnecessitated, they are not etched automatically in an etching process.

IPC: G03G21/00
Filed: 1998-06-12
Abstract: PROBLEM TO BE SOLVED: To stably supply an excellent image during a tube period by effectively removing transfer residual toner. SOLUTION: This device is allowed to hold a LCL cleaning roller 8 applied with cleaning bias thereon in contact with an intermediate transfer body 5, after the secondary transfer, to let polarity of the secondary transfer residual toner on the intermediate transfer body 5 reversely changed in positive, and simultaneously with the primary transfer, to inversely transfer the transfer residual toner from the intermediate transfer body 5 on a photosensitive drum 1. The secondary transfer residual toner being inversely transferred is removed by a fur brush 73 for removing the primary transfer residual toner.  Since the primary transfer residual toner is charged in negative polarity, while the secondary transfer residual toner in positive polarity, the cleaning bias applied from a cleaning bias applying power source 74 applying to the fur brush 73 is switched, at the time of removing the primary transfer residual toner, into positive, and at the time of the secondary transfer residual toner, into negative. This switching is performed associating with the LCL cleaning roller 8.

Abstract: PURPOSE:To obtain a microscopic pattern of less than 1mum, to easily produce a mask and to utilize an inspection technique and a correction technique on a conventional device by a method wherein a reduction optical system is installed between a first substrate and a second substrate along a traveling direction of X-rays. CONSTITUTION:A beam of X-rays 1 incident on a mask 2 travels at a reflection angle which is identical to an incidence angle as a reflection beam of X-rays which corresponds to a pattern drawn on the mask 2. The reflection beam of X-rays is incident on a concave spherical reflector 4 as a beam which has passed through a circular-arc-shaped opening by means of a light-shielding plate 7. The beam of X-rays 1 incident on the concave spherical reflector 4 is reflected at the reflection angle which is equal to the incidence angle and is converged onto a wafer; a reduced image representing a pattern of a circular-arc-shaped part on the mask is formed on the wafer. The mask 2 is of the reflection type which displays a contrast of the pattern due to reflection and absorption. As a reflection plane, a multilayered film where a thin film composed mainly of a heavy element and another thin film composed mainly of a light element are laminated alternately is used; a direct incidence optical system whose incidence angle is small is used; the spherical aberration can be reduced. Furthermore, a first substrate 2 and a second substrate 3 are arranged inside a perpendicular plane with reference to the reflector.
