Abstract: PURPOSE:To prevent an exposure surface from flawing by providing a swelling part with which a conveyor roller comes into sliding contact at both ends of the exposure surface, and eliminating the direct contacting between the roller and exposure surface when a recording medium is inserted. CONSTITUTION:A swelling part 18 which is lower than the thickness of a recording medium 13 is formed beyond the width of the medium 11 whih used a cathode-ray tube of an optical fiber, etc. Then, the conveyor roller 12 is in sliding contact with the swelling parts 18 and never contact the exposure surface 11a directly unless the recording medium 13 is inserted. Consequently, the recording medium 13 is inserted between the swelling part 18 during recording, but the roller 12 does not contact the exposure surface 11a when the medium 13 is not inserted, thereby preventing the surface from flawing.

Title: Vortex flowmeter
Inventor: KASHIMOTO HIROO
IPC: G01F1/32
Filed: 1994-07-01
Abstract: PURPOSE:To provide a vortex flowmeter the measurable range of which can be extended without adjusting the sensitivity of an ultrasonic transmitter and receiver. CONSTITUTION:A lower communicative hole group 7 and upper communicative hole group 8 formed in a vortex generating body 6 are respectively constituted of center-side and tube wall-side lower communicative holes 7a and 7b and center-side and tube wall side upper communicative holes 8a and 8b. In a low flow velocity range, the flow rate of a gas can be surely measured, since the gas flows through the communicative holes 7a and 7b and 8a and 8b of the hole groups 7 and 8. Since flow path of the gas can be formed through the holes 7a and 8b and the working distance of ultrasonic waves can be made sufficiently longer, the amount of modulation received by the ultrasonic waves becomes larger by the amount corresponding to the extended amount of the distance and the flow rate of the gas in a low flow velocity range can be stably measured with high accuracy without adjusting the sensitivity of an ultrasonic transmitter 10 and receiver 11. In addition, the measurable range of a vortex flowmeter can be expanded.

Title: Data retrieving device
Inventor: YOSHIDA HIROICHI
IPC: G06F17/30
Filed: 1990-06-29
Abstract: PURPOSE:To retrieve a character string having the number of characters equal to the retrieved characters out of a sentence in a time shorter than the time required for retrieving a full sentence by retrieving only the character string part having the same number of characters as the retrieved characters out of the head of a word belonging to a specific field after skipping the character string parts for each word belonging to the specific field. CONSTITUTION:A sentence stored in a sentence storage means 101 is divided by a syntax analyzing means 102 at the head positions of the words belonging to a specific field, and the number of characters included between the divided head positions of words is stored in an inter-wordlength storage means 103 as the inter-word length. When an optional word belonging to the specific field is inputted from an input means 104 as the retrieved characters, a retrieving means 105 refers to the inter-word length stored in the means 103 and retrieves only the character string part including the same number of characters as the retrieved characters out of the head of a word belonging to the specific field after skipping the character string parts for each inter- word length of each word. Therefore a character string having the same number of characters as the retrieved characters is skipped for each word belonging to the specific field and retrieved. Thus the corresponding character string is retrieved in a time shorter than the time needed for retrieving all characters.

Title: Looper driving mechanism for sewing machine
Inventor: SAKUMA KOICHI
IPC: D05B57/34
Filed: 1991-07-15
Abstract: PURPOSE:To provide the looper driving mechanism for an accurate and easy-to assemble sewing machine with less number of parts. CONSTITUTION:Looper driving cams 6 and 7 are made by fixing a cylindrical cam with an axis inclined by theta against a main axis 5. On the other hand, a looper driving fork which is a U-shaped cam follower is installed on the looper driving axes 6 and 7, and this fork is engaged with the inclined cam. The fork is installed with the degree of freedom absorbing the deviation of the shaft center of the main axis 5 and the looper driving axes 6 and 7 against the looper driving axes 6 and 7. Accompanied by the rotation of the main axis 5, the fork is rotated to rotate the looper driving axis by changing the inclination of the cam surface of the inclined cams 6 and 7 in the plane including the main axis 5 within the range of + or -theta. Thus, a smooth driving transmission is realized by the degree of freedom to install the form, resulting in preventing abrasion and backlash.
