Title: Packing module for cooling tower
Inventor: NARAKI HIROSHI
IPC: F28C1/16
Filed: 1992-11-18
Abstract: PURPOSE:To eliminate the need of a complicated construction of a head water tank and a damper which requires operation corresponding to the outside air conditions and make a packing module compact by a method wherein the width of a dry path is made narrower than that of a wet path. CONSTITUTION:Wet paths A and dry paths are formed inside a packing module of a cooling tower. In the wet paths A, sprayed water from a head water tank 11 comes in indirect contact with air flowing between heat exchange plates 1, and the air in the dry paths B is completely isolated from the sprayed water. In addition, the wet path A is about 18mm in width and the dry path B is about 12 in width, that is, the width of the dry path B is two-third the width of the wet path A, so that the temperature of air flowing through the dry path B is effectively raised and indirect heat exchange across the heat exchange plates 1 between warm water passing though the wet paths A and air passing through the paths B accounts for about 10% of the total calorie required for cooling, resulting in a reduction of the volume of the wet paths A.

Abstract: PURPOSE:To let mainly material gas flow only to the part along the surface of semiconductor substrate so as to decrease the supply quantity of material gas by providing a material gas supply port in the position along the passage of carrier gas and the upper stream side of the semiconductor substrate. CONSTITUTION:A material gas supply port 13 for sending material gas is provided at a reactor 1 separately from a carrier gas supply port 14 for sending carrier gas 6. The material gas supply port 13 is provided at the position along the passage of carrier gas 6, which is flowing a little to the surface of a semiconductor substrate 3, and near the semiconductor substrate 3 and on the upper stream side of the semiconductor substrate 3. Doing it this way, the carrier gas flows inside the reactor 1 as a laminar flow, so when material gas is supplied into the reactor 1 from the material gas supply port 13, the material gas 5 can reach the surface of the semiconductor 3 such that it creeps the surface of a susceptor 2 without being disturbed by carrier gas 6. As a result, the supply quantity of material gas can be decreased, and the yield of material can remarkably be elevated.

When the feeding-out molten steel is stopped, inclined furnace body is returned to its horizontal or forward slant attitude. At the time when molten steel and slag are not present at the upper part of the molten steel feeding-out port the rod 18 is lifted up and then the rod is turned and retracted from the above part of the steel feeding-out port. After that, a lid-like cover 24 for a tap hole is abutted against the steel feeding-out hole from below, filling material is loaded in a tapping tube 14 so as to close the tap hole 12 in advance.

Title: Etching process of semiconductor wafer and manufacture thereof having process thereof
Inventor: KATO TADAHIRO
IPC: H01L21/308
Filed: 1997-10-24
Abstract: PROBLEM TO BE SOLVED: To suppress formation of a locally deep pit and the increase of the depth, by etching a semiconductor wafer with at least two kinds of alkaline etching solution. SOLUTION: In alkaline etching solution whose selective ratio is small, the degree of selective etching of a surface-processing decomposition layer at an initial reaction stage is small, and the generation of a pit can be suppressed. Furthermore, in general when etching is performed with the alkaline etching solution having a high crystal anisotropy, it is known that the surface roughness of the surface of a silicon wafer increases. Therefore, when the semiconductor wafer undergoes alkaline etching, the etching is performed at a plurality of steps, the etching is performed by two or more kinds of the alkaline etching solutions, the etching at the first step is performed e.g. with the aqueous solution of NaOH in this case and the etching at the second step is performed by aqueous solution of LiOH.  Then, even when the surface processing decomposition layer or the like is present in the wafer, the increase of the locally deep pit and the depth is suppressed.

At that time, when there is no unevenness on the surface 2a, the shape of the picture 8 is similar to the shape of the nichrome wire of the heating element 1 and when there is unevenness, the picture 8 becomes a line with a distorted shape. The processor 6 inputs a reference picture in advance in the case irradiating the panel 2 in a normal state without distortion and when the processor 6 compares the signal 5 with the reference picture and decides there is abnormality, a command signal 11 is applied to the controller 9. Then, the controller 9 applies an alarm generation command signal 13 to an alarm generator 12 so as to generate alarm.
