Title: Drawing surface regulating mechanism in scan-type drawing device
Inventor: ANDO HIROAKI
IPC: B41J2/00
Filed: 1988-12-01
Abstract: PURPOSE:To enable a drawing surface to be contained within a depth of focus of a scanning lens even if undulation or the like exists on the drawing surface in the range of one scanning by allowing a drawing board part in a drawing surface mechanism of a scan-type drawing device to be inclined as well as being moved vertically. CONSTITUTION:An I/O controller transmits a signal inputted from a focal point detection system to a CPU. The CPU determines the drive amount of each AF motor based on said signal and returns the same to the I/C controller. On the basis of this drive amount, the I/C controller controls each of the AF motors through an AF motor driver and regulates the vertical position and inclined angle of a drawing board part 300 so as to position the drawing surface within the range of + or -15mum which is a depth of focus of an ftheta lens 500.

Title: Refining of gas and its device
Inventor: KIMURA MASAKI
IPC: C01B21/04
Filed: 1990-11-10
Abstract: PURPOSE:To ensure that gas is refined efficiently by introducing unrefined gas containing O2 gas as an impurity to a catalyst heated at high temperature to remove the O2 gas, and supplying H2 gas to the catalyst heated at high temperature for catalyst regeneration. CONSTITUTION:O2 gas is removed from unrefined gas containing O2 gas as an impurity by introducing the gas to catalysts 31, 32 heated at high temperature. To regenerate the catalyst, H2 gas is supplied to the catalyst heated at high temperature. Subsequently, each time for heating and cooling of the catalyst is no longer required and, therefore, both refining and regeneration processes can be performed efficiently using the catalyst. In addition, the ability of absorbing the impurity of the catalyst can be enhanced by heating at high temperature, and subsequently, a large flow rate of unrefined gas can be refined using a small amount of catalyst. Thus, the device can be made compact significantly.
