IPC: G01N25/22
Filed: 1989-08-08
Abstract: PURPOSE:To keep the relationship between an alcohol concentration detector and a liquid surface approximately constant by self-actuation by providing a float at the outer surface of a tubular member wherein a gas feeding pipe which is immersed into liquid to be detected is suspended. CONSTITUTION:An upper end 211 of a tubular member 21 is closed with an upper end closing member 20. A lower end 212 is an open end part. A gas feeding pipe 22 has a gas sending means 24. The lower end of the pipe 22 is immersed into a liquid to be detected. The gas feeding pipe 22 is made to penetrate through the upper closing member 20 and suspended in the tubular member 21. A lower end 221 is terminated at a part higher than the lower end 212 of the tubular member 21. A gas temperature detecting means 27 is provided in a gas sucking pipe 26. A gas-temperature-change detecting means 28 detects the change in gas temperature based on the detected temperature. The change in gas temperature is transduced into the concentration of alcohol to be detected, and the result is outputted. A float 31 is provided at the outer surface of the tubular member 21. An alcohol concentration detector keeps the relationship between the apparatus and a liquid level approximately constant by self- actuation, and the occurrence of measuring errors can be prevented.

Title: Video deck
Inventor: ITO TOSHIAKI
IPC: G11B15/675
Filed: 1997-07-30
Abstract: PROBLEM TO BE SOLVED: To newly load a video tape cassette without taking time when this new video tape cassette is to be inserted without becoming aware that some video tape cassette is already in the loading state. SOLUTION: The presence/absence of loading of a video tape cassette is detected and also the inserting operation of a new video tape cassette in the case that the above video tape cassette is in the loading state is detected by a system controller 80. When this inserting operation is detected by the system controller 80, the video tape cassette in the loading state is automatically ejected out. Consequently, even when the new video tape cassette is inserted without becoming aware that the previous video tape cassette is in the loading state, this new video tape cassette can be loaded without taking time.

Title: Production of magnetic recording medium
Inventor: ATOBE MITSUAKI
IPC: C10N40/18
Filed: 1987-08-18
Abstract: PURPOSE:To lower the coefft. of friction between a memory medium and head and to enhance the mechanical reliability of the memory medium by pulling up a substrate surface on which a thin carbonaceous film is formed at an equal speed while rotating a liquid lubricant or solid lubricant. CONSTITUTION:The substrate surface formed with the thin carbonaceous film on a thin metallic film medium is pulled up at the equal speed while the liquid lubricant or solid lubricant is kept rotated. Namely, a hard film coated base body subjected to an alumite treatment or nonmagnetic plating treatment such as Ni-P plating is subjected to polishing for formation of a specular surface and thereafter a magnetic film is formed thereon to constitute the substrate. The lubricating agent is coated on the magnetic recording medium constituted by forming a protective film consisting of SiO2, TiC, C, MoW2, etc., on the substrate formed in such a manner while the disk is kept rotated. This coating is intended to uniformize the lubricating layer in the circumferential direction of the disk. The rotating speed of the disk is adequately about 1-100rpm. The coefft. of friction is thereby greatly improved and the mechanical reliability is enhanced. Since the lower floating is possible as well, the higher density recording is sufficiently possible.

CONSTITUTION:This bismuth laminar compd. contains 0.02-0.25wt.% (expressed in terms of MnO) Mn in a compd. represented by a chemical formula (M11-2XM 2XBi4+X)Ti4O15 (where M1 is alkaline earth metals including at least Sr, M2 is alkali metals and 0.06<=x<=0.44). Since this compd. contains the alkaline earth metals and alkali metals in a prescribed ratio, unevenness in the sensitivity of the piezoelectric property to temp. is reduced though the reason is unknown and this compd. can be used with high sensitivity over a wide temp. range. Since this compd. contains the prescribed amt. of Mn, the sensitivity can be enhanced without causing hysteresis to pressure-electric charge output.

Title: Page image retrieval method/device
Inventor: TANOSAKI YASUO
IPC: G06K9/00
Filed: 1994-08-30
Abstract: PURPOSE: To improve the hit rate of the desired page image data against an inputted key word. CONSTITUTION: An external storage 3 stores the image data on the page image read by an OCR 5 and the retrieval code data obtained by recognizing the characters included in the text data part of the image data with relationship secured between both data. The retrieval data also include the next candidate character that is produced through recognition of characters. A controller 2 retrieves the retrieving code data including the key word inputted through an input device 1 and also retrieves the next candidate character as a retrieval object. Thereby if the corresponding retrieval code data can be obtained, the number of the image data related to the retrieving code data is shown on a display device 4.  Thus the next candidate character is also retrieved and therefore the hit rate of a desired pace image is improved by a key word as long as the 1st candidate character is wrong recognized and the next candidate character is correctly recognized respectively.
