Title: Charging method for sintering raw material
Inventor: FUJIMOTO MASAMI
IPC: F27B21/10
Filed: 1986-06-02
Abstract: PURPOSE:To control the charging density of the sintering raw material on a pallet so as to improve air permeability and to improve the productivity of sintered ore by using a raw material charger disposed with plural bar materials each having a specific shape at the time of supplying the sintering raw material onto the rotary pallet of a sintering machine for iron ore. CONSTITUTION:The sintering raw material 4 such as powdery iron ore, coke and quicklime is discharged from a hopper 1 onto the rotary pallet 9 of the sintering machine by a drum feeder 2. The raw material charger inclined near to the surface of the pallet 9 is mounted to the lower part of an inclined sloping plate 3 on which the sintering raw material 4 falls. The charger is mounted with the plural bar materials 7 so as to have the smaller width on the entry side of the pallet 9 than on the deliver side and to have the wider spacing from the lower part toward the upper part. The raw material, passing the charger, forms layers on the pallet 9 in such a manner that the coarse grains in the raw material come to the lower side and the pulverized powder comes to the upper side. The densities of the raw material layers 8 are smaller from the upper part toward the lower part and since the air permeation rate from the upper part is not hindered, the sintered ore having the excellent strength is efficiently produced at a high speed.

Title: Pattern forming method
Inventor: TANAKA TOSHIHIKO
IPC: G03F7/20
Filed: 1985-06-12
Abstract: PURPOSE:To enable a resist pattern to be formed as per the designed size regardless of the size and shape of the pattern by changing the optical transmittance of the optically transmissive portion of a mask in dependence on the pattern size and shape. CONSTITUTION:Using an apparatus comprising a substrate wafer coated with a resist, a light source for exposure, and a mask for pattern transfer, a latent image is formed by projecting an exposure light from the light source for exposure through the mask to expose the resist film, and thereafter development is carried out to form a pattern. In such pattern forming method, the optical transmittance of the optically transmissible portion of the mask is changed in dependence on the pattern size and shape. Exposure is performed using a mask (reticle) which has the respective patterns in the shape of a lattice, isolated line or hole having a pattern size of, e.g., 0.6-5mum, the optical transmittances of which respective patterns have the values as shown. In this case, a thin film of Cr is evaporated on the reticle, and the optical transmittances are changed by changing the film thickness.
