Title: Mfr. of foamed surf-boards - using paper-lined mould with one flat and one concave half
IPC: B63B35/79
Filed: 1982-01-18
Abstract: Process for the mfr. of contoured blocks of rigid polymer foam, with one flat face and one curved face, employs a mould in two halves, one of which is flat and the other curved, the join-line of the mould halves being in the same plane as the flat half. To allow release from the mould, a layer of ordinary heavy-duty (Kraft) paper is used between each mould half and the foamed resin resin. Used esp. for prodn. of wind-surfing and surf boards. Compared to processes using two concave mould halves, the moulds are cheaper, no special extensible paper is needed for the upper mould half and less labour is needed to maintain the paper in position. Less resin is wasted.

Patent FR-2515873-A1 (FR)
Inventor: NAKASUJI MAMORU
IPC: H01J37/317
Filed: 1982-09-30
Abstract: In a mask for an electron-beam projection system, a Cr layer (12) which selectively absorbs UV rays is deposited on the surface of a quartz substrate (11), transparent to UV rays, in such a way that a pattern which is transparent to UV rays is produced. The pattern comprises a first region (15-1) which is larger than a specified width and a second region (15-2) which is smaller than the specified width. However, a metal film (13) is provided on the Cr layer (12) and the first region (15-1) of the pattern but not on the second region (15-2). In the first region (15-1), the metal film (13) is thicker in the central part than in the peripheral part. The contrast transmission function for UV rays of the second region (15-1) is consequently higher than the corresponding function of the first region (15-1). In addition, said contrast transmission function is higher in the peripheral part of the first region than in its central part.
