Title: Optical recording information reader
Inventor: KANEKO ATSUSHI
IPC: G11B7/095
Filed: 1989-12-20
Abstract: PURPOSE:To make a tilt servo system satisfatorily follow a disk under its ware state by raising a response characteristics in a comparatively high frequency of the servo system more than its standard moving speed when a read light beam spot is moved at high speed. CONSTITUTION:When optical pickups 24a and 24b are moved in the radial direction of the disk at high speed, the response characteristics in a comparatively high frequency of the tilt servo system is raised, and after the high speed movement of the optical pickups 24a and 24b is finished, the response characteristics of the tilt servo is restored to its original state. A loop switch 32 is opened due to characteristics of a tilt error detector 25 in order to turn off the tilt servo system when the pickups reach the neighborhood of a position of nonexistence of a recording track on a recording surface of the disk. By this method, even when the optical pickups are under high speed movement in the disk radial direction, a nearly optimum orthogonal state of an optical axis of a recording information read light beam to the disk recording surface is always maintained, so that recording information is stably retrieved.

Title: Single-head piston type compressor
Inventor: KIMURA KAZUYA
IPC: F04B27/10
Filed: 1996-12-09
Abstract: PROBLEM TO BE SOLVED: To provide a single-head piston type compressor constituted so that the rotation and inclination regulating structure of a piston may not cause the piston to be damaged at the time of assembling a housing. SOLUTION: This compressor regulates the rotation and inclination of a single-head type piston 32 by bringing a guide recessed part 61 formed in a front housing 11, and a guide protruding part 62 which is formed at the piston fitted in the guide recessed part 61 into contact with each other. Therefore, the sliding contact parts between the piston 32 and a cylinder bore 31 do not require receiving inclination moments M1-M4 working upon the piston 32. It is thus possible to form the piston 32 into such a lighting hole shape as only a seal part 33 is brought into contact with the cylinder bore 31.

IPC: C12H1/16
Filed: 1996-12-09
Abstract: PROBLEM TO BE SOLVED: To stably store a liquor such as Japanese rice wine or wine for a long period by deaerating the liquor and subsequently storing the liquor. SOLUTION: This method for storing a liquor comprises passing a raw liquor through a filtration device 1, removing gaseous components contained in the raw liquor by the use of a deaeration device 2, and subsequently storing the deaerated raw liquor in a storage container 3.
