Patent JP-H11162866-A (JP)
Title: Manufacture of semiconductor device
Inventor: FUJISAKI MITSURU
IPC: H01L29/78
Filed: 1997-12-02
Abstract: PROBLEM TO BE SOLVED: To shorten the manufacturing time of a semiconductor device with LDD structure. SOLUTION: On a silicon substrate 1, a thermal oxide film 2, a polysilicon film 3, a TEOS film 4 are formed in this order. Then, the TEOS film 4 is etched to form a mask pattern 4a to be used as a mask for etching the polysilicon film 3. After that, the polysilicon film 3 is etched into a mask pattern 6 with a mask pattern 4a as a mask. The mask pattern 6 is formed into such a shape that it has a tapered section 6a, which becomes gradually thinner from the end of a region where a gate electrode is to be formed toward a region where a high density diffused layer 12 is to be formed, while covering a region where a gate electrode is to be formed and a region where a low density diffused layer 11 is to be formed.  By conducting ion implantation with this mask pattern, a region under the tapered section 6a becomes an impurity diffused layer of a lower density than the region, where the high density diffused layer 12 is to be formed since the tapered section 6a serves as a mask, and this is equivalent to a case where the low density diffused layer 11 is formed between a region where a gate electrode 7 is to be formed and the high density diffused layer 12.

Title: Device for supplying culture water
Inventor: YAMADA SHIGERU
IPC: A01K63/04
Filed: 1998-11-24
Abstract: PROBLEM TO BE SOLVED: To provide a device for supplying culture water, capable of maintaining a water quality and an environment suitable for the growth of aquatic organisms without using a chemical agent. SOLUTION: Water supplied from a water source is brought into contact with a metal fiber woven fabric received in the device for supplying culture water. Since a fine amount of a metal ion (for example, silver ion or copper ion) eluted from the metal fibers is added to the water, pathogenic bacteria or bacteria for preventing the growth of aquatic organisms are sterilized to inhibit the growth of the bacteria. Thus, a water quality and an environment suitable for growing aquatic organisms can be maintained, and the sterilization action and the antibacterial action of the metal ion water are stably obtained for a long period.

IPC: G06F9/28
Filed: 1987-12-29
Abstract: PURPOSE:To effectively execute a pipe line processing and to prevent a processing speed from deteriorating even in the middle of processing a condition branch instruction by continuously fetching a micro instruction on a non-branch side while the condition of the condition branch instruction is not realized. CONSTITUTION:An instruction fetch processing part 2 which fetch-processes the micro instruction in the pipe line processing, and an execution processing part 3 which executes processings except for said processing are included in the title processor. The execution processing part 3 decides the realization or non-realization of the branch condition, and outputs a decision result signal SJ showing the result of the decision to a selection means 6. When branch is not realized, next address information NA is selected and is added to a micro ROM4 as address information AD. When branch is realized on the other hand, branch destination address information BNA is selected and is added to the micro ROM4. Thus, the fetching operation of the micro instruction MO is continuously executed when branch is not realized, and the effect of the pipe line processing can effectively be displayed and is speeded up.

IPC: B41M3/14
Filed: 1987-12-28
Abstract: PURPOSE:To reveal a concealed character or figure easily, by providing a print body where a halftone section having different moire interference angle is printed in the form of a character or a figure into a halftone section and a halftone see-through body which moire interferes with the halftone section having different moire interference angle then applying the halftone see-through body onto the print body. CONSTITUTION:When a character 1 or a figure 1' is printed, halftone section A is printed simultaneously onto two other sections. A print body (a) where a halftone section B having a different moire interference angle is printed in the form of a concealed character 3 or a concealed figure is printed in the halftone section A and a mesh point see-through body (b) which moire interferes with the different angle halftone section B are provided, then the halftone see-through body (b) is applied onto the print body (a) in order to reveal the concealed character 3 or figure. Since the difference angle halftone section B constituting the concealed character 3 or figure is arranged in same condition as the halftone section A, no character nor figure is revealed when the section B is viewed directly with eyes. When the halftone see-through body (b) is applied, the concealed character 3 or figure is revealed because the section B has different moire interference angle from that at the section A and only the concealed character 3 or figure moire interferes with the halftone see-through body (b).
