Title: Carbonate water producing device
Inventor: KAZUMA YASUO
IPC: A23L2/00
Filed: 1995-05-31
Abstract: PURPOSE: To rapidly produce carbonate water having a high carbon dioxide content and having good taste to drink by providing the front end of a spray with a cylindrical guide which is fixed at one end to the spray and is opened at the other, making water drops smaller by the collision against this guide and bringing the water droplets into collision against the water stagnating in a pressure vessel. CONSTITUTION: The front end of the spray 9 is provided with the cylindrical guide 11 which is fixed at one end to the spray 9 and is opened at the other end. The sprayed water, then, collides against the inside wall surface of this cylindrical guide 11 and splashes in the form of very small water droplets which absorb carbon dioxide. The very small water droplets emitted from the cylindrical guide 11 collide against the water stagnating in a carbon dioxide pressure vessel and involve the carbon dioxide to generate many very small air bubbles by which the carbon dioxide is mixed with the water. The tasteful carbonate water is easily and rapidly produced in such a manner.

Inventor: OSADA SHIGEMI
IPC: G06V10/20
Filed: 1982-09-09
Abstract: PURPOSE:To extract an area, where an individual character exists, from a character string where characters are written closely by defining the area, which is surrounded with a prescribed window and the shortest route, as the area of existence of one character and separating and extracting this area successively. CONSTITUTION:In respect to pictures 111, 112, and 113 which are cut from the character string by a rectangle 12 larger than the circumscribed rectangle of the character string by the length corresponding to one picture element in both directions, the window 13 which is vertical the direction of the character string and has a length equal to the width of the rectangle 12 and has a width corresponding to one picture element is scanned from one end of the rectangular area. The position where a black picture element 14 appears first in the window 13 is detected, and a search area of the shortest route between picture elements S and E which exist in both ends of the window in this position is limited in the scanning direction from the position of the window 13 to find the shortest route. As the result, the area surrounded with the window 13 and the shortest route is defined as the area of existence of one character, and this area is separated and extracted successively, and thus the area where the individual character exists is extracted.

Title: Record/reproduction method
Inventor: OGINO MASANORI
IPC: G11B7/125
Filed: 1978-12-22
Abstract: PURPOSE:To realize the high-density recording and reproduction by carrying out the recording and reproduction with insertion of the pilot signals or the frequency region different with every adjacent tracks into the main signal bit row for the recording and reproduction and thus realizing the recording to the disk without grooves or the like via one piece of the light beam. CONSTITUTION:Gate 11 and switch 9 are controlled via input switch pluse 8, and adder 12 generates the composite pilot signals obtained by piling the pilot signals of different frequency regions and given from switch 9 onto the frequency signals which pass through gate 11 with every turning cycle of the disk. This composite signal is then added to the main signal underwent the FM modulation at adder 13 to be turned into the signal in which the pilot signal of different frequency regions with every adjacent track is added into the main signal bit row. Accordingly, the light beam exclusive for the pilot signal becomes unnecessary with use of the light beam which is modulated by the signal obtained above. And thus the high-density recording becomes possible for the disk with no groove via one piece of light beam. At the same time, the before- and after-pass states of the track can be decided by the pilot signals featuring different frequency regions with every adjacent track at the reproduction, thus ensuring the simple and assured tracking.

Title: Comb line filter
Inventor: KATAKI MASAYOSHI

Filed: 1987-06-25
Abstract: PURPOSE: To simplify the constitution of a comb line filter by using a glass delay line which has a wide band, flat frequency characteristics, and low characteristic impedance for the filter and increasing the input level of a video signal.  
     CONSTITUTION: The glass delay line DL 1  has a 3.58MHz±1.1MHz, flat frequency characteristics, and characteristic impedance about 1/2 as large as that of a conventional delay line. A filter circuit increases the level of the input video signal to 4∼5 VPP, and VR 1  and L 2  balance the input and output sides and also correct the characteristics. Thus, the input level of the video signal is increased, so a delay line insertion loss compensating amplifier can be omitted, and a phase distortion correcting circuit can be omitted because of the wide band and flat frequency characteristics of the glass delay line DL 1 . Further, the characteristic impedance of the glass delay line DL 1  is low, so a buffer amplifier for an output signal can be omitted.
