Title: Water-surface running ship
Inventor: OZAWA SHIGEYUKI
IPC: F01N13/00
Filed: 1995-08-15
Abstract: PROBLEM TO BE SOLVED: To prevent any drop in engine output from occurring as exhaust resistance is increased though a catalytic converter is cooled by a large quantity of engine cooling water. SOLUTION: A catalytic converter 23 is installed in an expansion part 19 of an exhaust pipe in an interposing manner. Two cooling water passages W2 and W3, covering an outer boundary of the catalystic converter 23 and leading to the downstream side from the upstream side of this converter 23, are installed in the expansion part 19. Cooling water in these cooling water passages is discharged into an exhaust passage in the downstream side of the catalytic converter 23. In addition, a cooling water takeout pipe 32, conducting the cooling water outboard, is interconnected to the more upstream than a cooling water exhausting part and to the more downstream than the catalytic converter 23 in these cooling water passages.

Title: Image processing method, image processor and fingerprint image input device
Inventor: ISOBE YOSHIAKI
IPC: G06T7/00
Filed: 1998-07-23
Abstract: PROBLEM TO BE SOLVED: To provide the image of desired image quality by performing a correction processing for absorbing characteristics intrinsic to an image pickup system. SOLUTION: The point spread function of the image pickup system (converging device 102, detector 103, analog circuit 104 and A/D conversion circuit 105) is estimated from an edge profile photographed by placing an edge on an image pickup surface 101 and a filter is prepared based on the point spread function. By using the filter, a finger print image photographed by placing a fingerprint on the image pickup surface 101 is corrected and the intrinsic characteristics of the image pickup system are absorbed. Thus, the image of the desired image quality not controlled by the characteristics intrinsic to the image pickup system is obtained.

Title: Speaker system
Inventor: FUJIHIRA MASAO
IPC: H04R1/02
Filed: 1998-07-23
Abstract: PROBLEM TO BE SOLVED: To obtain a speaker system where the electroacoustic transduction efficiency is enhanced by applying a reaction with respect to an action caused by a diaphragm of a speaker to a 2nd diaphragm formed in a speaker box and rocking of the speaker box with a light weight is prevented. SOLUTION: A 2nd diaphragm 30 is provided to a rear side of a magnetic circuit 27 with respect to a vibration system including a 1st diaphragm 7 being a component of a speaker unit A and the 2nd diaphragm 30 is constituted of a rear plate 35 of the speaker box 21 in the speaker system. Thus, since all the generated forces are delivered to the 2nd diaphragm 30, the transduction efficiency from electric energy into acoustic energy is enhanced. Furthermore, since reaction-F1 with respect to an acting force F1 produced when driving the 1st diaphragm is not delivered to the speaker box, distortion is reduced and a low frequency sound is extended.

Title: Very low temperature refrigerator
Inventor: FUJIMOTO SHUJI
IPC: F25B9/14
Filed: 1989-08-10
Abstract: PURPOSE:To reduce the generation of wear of a sliding part between a vane and an inner periphery surface of a casing by communicating a room temperature chamber in an expander with a low temperature chamber by way of a cold accumulator. CONSTITUTION:A high pressure switch over valve 12 and a low pressure switch over valve 13 are opened and closed alternately, synchronizing with the reverse operation of a body of revolution. A refrigerant gas from a compressor 1 is supplied to an expansion chamber 8 of an expander 2. Where a room temperature chamber 9 of the expander 2 is communicated with a refrigerant pipeing 11 between a cold accumulator 14 and the switch over valves 12 and 13. Therefore, the room temperature chamber 9 is communicated with the low temperature expansion chamber 8 by way of the cold accumulator 14 so that the pressure may become identical to the expansion chamber 8, thereby eliminating the differential pressure between both the chambers 8 and 9. It is, therefore, possible to reduce a sealing performance induced by the vane 7 and increase the energization force of a spring 6, which eliminates the need to thrust the vane 7 to the inner periphery surface of the casing 3 with large force and reduces the wear of the sliding part between the vane 7 and the inner periphery surface of the casing 3.
