Title: Leakage oil detector for underground tank
Inventor: NAKAMURA YOSHIHIRO
IPC: B65D90/22
Filed: 1987-09-14
Abstract: PURPOSE: To instantly detect oil leak automatically by furnishing the gas detection tube of an underground oil tank with a gas sensor and connecting it to a detection display unit. CONSTITUTION: Oil leaking from a tank 4 into the surrounding ground is introduced to a gas detection tube 6a placed at four corners of the tank 4. Leakage oil enters into an outer tube 7b through a hole 8b and then into an inner tube 7a through a hole 8a, but ground sand or dust does not enter together with oil because holes 8a and 8b do not face to each other. Gas generating from leakage oil in the inner tube 7a is detected by a gas sensor 10a. Its output signal is delivered to a signal generator 19a, a selector 20 of a detection display unit 13 in an office 5, a receiver 21, and then a comparator 22. In the comparator 22, the detection amount based on the sensor output signal is compared with the normal gas sensor signal level registered on a memory 23.  If the value from the gas sensor 10a is larger than the normal value, a leak indication signal is issued to an alarm 18, and a lamp 17 indicates the location of leak source.

Title: Feed mechanism for optical pickup
Inventor: SAKAI TSUNEMI
IPC: G11B21/02
Filed: 1996-09-03
Abstract: PROBLEM TO BE SOLVED: To obtain a feed mechanism which prevents a sliding part from being worn away and which can keep the positioning accuracy of an optical pickup by a method wherein a groove stripe part in which grease is stored is formed on the sliding face of a guide rail. SOLUTION: When an optical pickup 5 is moved, a height-positioning part 15 and a leaf spring 16 are slid with reference to sliding faces 14a, 14b of a guide rail 14 so as to regulate its movement in the height direction. A sliding resistance which is generated in the movement of the pickup 5 is reduced by grease 18 with which the sliding faces 14a, 14b are coated. In this case, since the grease 18 is stored in a groove stripe part 17 on the sliding face 14a, it is possible to prevent the grease 18 from being scattered or from flowing out, and the life of the lubricant becomes long. In addition, the groove stripe part 17 is formed on the guide rail 14 so as to be parallel with the movement direction of the pickup 5, and the amount of the grease 18 in a part in which the sliding resistance is high is ensured sufficiently.  As a result, a lubricant effect is increased, and the sliding resistance is reduced with good efficiency.
