Title: Device for preventing inside of water storage tank from being stained
Inventor: TAKADA SHIGERU
IPC: B08B9/087
Filed: 1999-07-29
Abstract: PROBLEM TO BE SOLVED: To prevent water quality from being deteriorated by impurities which are contained as inorganic matter and organic matter in the water remaining in a water storage tank installed on the rooftop of a building or other places, are deposited on the inner face of the tank and generate lumps of water scales to become culture media of unwanted bacteria and to facilitate cleaning work for removing such impurities. SOLUTION: A holder 6, to which a cleaning/wiping tool 7 such as a brush is fit for sliding on the inside of the water storage tank 1, is rotated and driven to dust/wipe the surface of the inner wall of the tank 1 so that the impurities are not adhered. Even when the impurities are adhered to the surface of the inner wall in every corner, they are scraped off while they remain soft, made to flow into drainage by dissolving them in the water again or as they are in solid states and discharged to the outside of the tank 1 so that they are not accumulated and firmly fixed.

Title: Method and device for plotting
Inventor: ASHIDA ISAO
IPC: G03F1/70
Filed: 1998-07-30
Abstract: PROBLEM TO BE SOLVED: To realize correct reversal plotting even in the case of plotting data which cannot be reversely plotted by a conventional method. SOLUTION: This plotting device is provided with plural plotting pattern files and a plotting job file showing the arrangement of the pattern files so as to plot a reversal image with respect to a pattern image by using the files. When a pattern is plotted in order to produce a mask, the contour of the pattern expressed in the pattern files 71 and 72 which should be plotted is extracted and a part outside the contour is filled with the pattern 101. Thus, an area outside the outline is prevented from being plotted after being inverted.

Title: Control unit of automatic vending machine
Inventor: KIKUYAMA TOSHIYA
IPC: F25D11/00
Filed: 1997-07-25
Abstract: PROBLEM TO BE SOLVED: To protect a compressor motor and other electric accessories even if the power source has a momentary break or generates an overvoltage. SOLUTION: An operational amplifier OP1 detects the source voltage of the automatic vending machine dropping below a specific voltage and a timer T is started. At this time, the contact R1 C of a relay R1 is broken to stop the compressor motor CM and then the compressor motor CM is not restarted for the set time of the timer T even if the source voltage recovers thereafter. Further, an operational amplifier OP2 detects the source voltage rising above the specific voltage and the contact R2 C of a relay R2 is turned off to stop all the electric accessories of the automatic vending machine cooling system. Then when the source voltage recovers to its normal value, the contact R2 C of the relay R2 is turned on, but the compressor motor CM is not restarted for the set time of the timer T by turning off the contact R1 C of the relay R1 .

Title: Method and device for retrieving data
Inventor: ITO TAMOTSU
IPC: G06F17/22
Filed: 1987-08-28
Abstract: PURPOSE:To decrease the number of blocks and characters which undergo comparison at retrieval and to shorten the data retrieving time, by collecting many headwords to divide them into blocks and gathering the head headwords of each block to form a higher level subindex file. CONSTITUTION:The head headwords of each block of a data file are collected for production of a subindex file 200 of a 1st hierarchy. In this case, each block of the data file is decided based on the minimum data handling unit of an external memory 1 storing a large capacity data file. In case the file 200 covers plural blocks, the head headwords of each block of an index file of the 1st hierarchy are collected for production of a master index file 300 of a 2nd hierarchy. The same operation is repeated until the size of the index file is equal to the value less than a single block, i.e., an n-th hierarchy. Then these index files are read out successively in the order of lower hierarchies.
