Title: Combined bi-directional air pump and method of delivering air
Inventor: KO EITETSU
IPC: F04B33/00
Filed: 2001-02-21
Abstract: PROBLEM TO BE SOLVED: To provide a combined bi-directional air pump and the method of delivering air. SOLUTION: The air pump for a bicycle has a head connected to an air filling mechanism and two air filling cylinders. When the air pump is used, a user grips the left and right air filling cylinders with both hands, and by utilizing the human behavior of the user of swinging both hands to left/right, matching the principle of human dynamics, the user operates the two air filler cylinders to reciprocate for filling a tire of an bicycle with air with even force, then the air is compressed with the force of the user's both hands completely acting on the cylinders. As a result, the force can be easily controlled, and the air pump can be stably operated with the increased speed of delivering air. The cylinders are connected to both left and right ends of the head respectively.  The types of the connected cylinders may be combined with an A type air pump cylinder, a B type air pump cylinder, a large cylinder or a small cylinder, and other different types of cylinders. The head and the cylinders can be separated and stored in a storage box to reduce the storage space. In addition, when the head or cylinders are broken or wear away, the broken/worn-out part can be changed alone, so that the air pump can be continuously used. Thus, the combined bi-directional air pump and the method of feeding air provided here have the novelty, practicality, and economical efficiency.

Title: Refrigerator
Inventor: OKABE YUICHI
IPC: F25D23/00
Filed: 2001-02-22
Abstract: PROBLEM TO BE SOLVED: To provide a refrigerator in which assembling work is simplified and recycle is taken into account in the design. SOLUTION: Since a protrusion is provided between an inner box and a baffle plate in order to prevent chill from flowing to the periphery of the U-shaped section at the side part of heat exchanger tubes, chill is prevented from flowing into an interconnection passage on the periphery of the U-shaped section. Since ventilation can be prevented at that part where heat is not exchanged easily, heat exchange efficiency can be enhanced and use of sealing material for filling the gap on the periphery of the U-shaped section can be minimized. Consequently, assembling work of the refrigerator is simplified and recycle can be taken into account in the design.

Title: Track jump controller and the track jump method
Inventor: ONO HIROYUKI
IPC: G11B21/08
Filed: 2001-03-06
Abstract: PROBLEM TO BE SOLVED: To accurately perform track-on on a target track. SOLUTION: A disk unit 10 includes a DSP 36 which controls each circuit component under instructions of a MCU 44. During jumping, a DSP core 36a detects the zero cross period of the last TE signal. An object lens 14 is controlled to move between the adjacent tracks at almost constant speed, by applying the acceleration pulse of a predetermined first level to a driver 38b when the detected zero cross period is behind a target value, and by applying the deceleration pulse of a predetermined second level to the driver 38b, on the contrary, when the zero cross period is faster than the target value. When the zero cross period is remarkably slower than the target value, the DSP core 36a largely accelerates the object lens 14, and prevents the moving direction of the object lens 14 relative to a disk 22 from being reversed. Accordingly, the number of jumped track lines is not miscounted.
