Title: Assembling of car regenerator
Inventor: HARUTOMUUTO BORUTSU
IPC: F01P11/20
Filed: 1993-12-06
Abstract: PURPOSE: To facilitate pressure reduction-heat insulation by fixing a casing cover to the casing of a latent heat storage unit and coupling the cover airtightly, interrupting heat insulation and pressure reduction and opening a pressure reduction chamber before taking out a motor vehicle latent heat storage unit. CONSTITUTION: An assembly of a casing 3 and a latent heat storage unit 2 is fixed to a pressure reduction chamber 11 having means 12 for fixing a casing cover 8. The casing cover 8 is fixed to a corresponding open part of the casing 3 and the entirety is placed in the pressure reduction chamber 11 which is then exhausted and brazed. When the casing 3 and the latent heat storage unit 2 are placed in the pressure reduction chamber 11, the chamber 11 is closed, exhausted and pressure is reduced adiabatically. In the pressure reduction chamber 11, the cover 8 is fixed to the casing 3 which is jointed airtightly to the cover 8. The cover 8 is subjected to welding or brazing after the casing is exhausted. Consequently, heat insulation and pressure reduction are stopped, the pressure reduction chamber 11 is opened and a motor vehicle latent heat storage unit 1 is taken out.

Title: Alignment optical system of optical aligner
Inventor: SASE YOSHIMITSU
IPC: H01L21/027
Filed: 1990-11-14
Abstract: PURPOSE:To eliminate a random noise without decreasing a resolution of an alignment signal by changing a position on an alignment mark on an exposed object where light is to be cast in any direction with an angle of incidence fixed. CONSTITUTION:The light which has passed through a lens 19 is cast on an entrance pupil 10 of a projection lens 2 after passing through an alignment window 9 which is located at a different position from a circuit pattern 6 of a reticle 1, to be cast on an alignment mark 4 on a wafer 3. A position on the alignment mark 4 where the light is cast can be changed freely by changing an angle of polarization of a galvanomirror 12. However, an angle of incidence of the light to the wafer 3 is fixed since the light passes through the specified position of the entrance pupil. The light which has reflected on the surface of the wafer 3 forms an image on a photo detector 17. Image information on every position where the light is cast is stored in the photo detector 17 and the accurate positions of the alignment mark 4 and a circuit pattern 7 are found by detection signals. Then, alignment is finished. Consequently, the detection signals can be leveled even where coherent light is used and therefore the signals can be free from an effect of a speckle component, a random noise, without reducing a resolution.
