Title: Hollow o-ring
Inventor: YAMAGUCHI TERUAKI
IPC: F16J15/08
Filed: 1996-04-19
Abstract: PROBLEM TO BE SOLVED: To improve the heat resistance of a conventional rubber O-ring and the sealing capability of a conventional centrifugal gasket by covering the outer periphery surface of a metallic hollow O-ring at least partially with flexible expansion graphite tape. SOLUTION: Expansion graphite tape whose sealing capability and heat resistance are excellent is applied onto the outer periphery surface of a hollow O-ring 1 made of SUS 304 with adhesives to form a covering layer 2. The covering layer 2 is formed at a contact surface between a flange and the O-ring at least. Use of the O-ring 1 with heat resistance and compression capability and the flexible covering layer 2 provides excellent heat resistance, matching with a flange even at a low tightening load, improved sealing capability, a large amount of compression, facilitates following the flange having distortion, improper parallelism or the like, and provides expectable sufficient sealing capability for an existing large-diameter flange. It is thus possible to improve sealing capability of a conventional centrifugal gasket, and solve concerns in handling such as missing of an inner race or outer race.

Title: Quick coupling part device
Inventor: EKMAN THURE
IPC: F16L37/23
Filed: 1996-04-19
Abstract: PROBLEM TO BE SOLVED: To hold parts each other even in the case where the medium pressure is high or a peak of the medium pressure exceeds a specified value by providing a surface layer having flexibility without generating a crack in a locking member of an engagement part (nibble). SOLUTION: A surface layer 9 is relatively soft, and has elasticity so that a ball 5" is sunk in the surface material and generated a cap-shaped contact surface 5a larger than that of a point contact. The surface layer 9 is formed so that the ball 5" can be sunk without generating a fine crack. A part 11 of the surface layer 9 for generating a cushioning work of the surface layer 9 is generated by the elasticity of the surface material, and this part for generating the cushioning work increases the ball 5" supporting force without generating a crack of the surface layer 9 and the ball 5". When the force F is eliminated, a constant bounce work can be obtained by the surface layer 9. This work is fully or partially generated so as to cope with the height of the cap.

Title: Automatic both-side copying device
Inventor: YAMADA YASUSHI
IPC: G03G21/14
Filed: 1990-05-11
Abstract: PURPOSE:To improve productivity in the case of both-side copying and to make a device easily comply with paper jamming when it occurs by making a counted value set in a timer by a timing setting part such a value that a copying paper to which copying has been performed on its 1st side reaches a paper ejection switching part after the copying paper to which copying has been performed on both sides is ejected from a final ejection port. CONSTITUTION:The counted value set in the timer 120 by the timing setting part 111 is made such a value that the copying paper to which copying has been performed on the 1st side reaches the paper ejection switching part after the copying paper to which copying has been performed on both sides is ejected from the final ejection port. As a result, the copying paper from the paper feeding part of a main body is fed just before a resist roller 62 by a paper feeding roller 61 in timing before final ejection and after the last copying paper fed from an inversion and transfer part(ADU) passes the resist roller 62, and reaches the paper ejection switching part after the last copying paper where both-side copying has been performed is finally ejected. Thus, the productivity is improved in the case of both-side copying and even in the case that paper jamming occurs at the final ejection port, the device complies with the paper jamming.

Title: Cooling plate for layered product of fuel cell
Inventor: BREAULT RICHARD D
IPC: H01M8/02
Filed: 1995-05-22
Abstract: PURPOSE:To reduce the thermal stress applied to cell stacks, while maintaining an excellent thermal conductibility and the electron conductibility. CONSTITUTION:This cell cooling plate 2 is composed of a plate in which a meandering cooling pipe 18 made of graphite particles combined through a fluorine resin is buried. The component member of the cooling plate 2 is not porous, and the graphite particles are preferable to be flake form, and since the graphite particles are filled very closely, the amount of a polymer binder can be made small. This cooling plate 2 exercises an excellent thermal conductibility and electron conductibility, and the movement of the electrolyte between cells resulting from the cell structure is prevented. In order to reduce the thermal stress applied to cell stacks, the structure of the cooling plate 2 is converted step by step to give the varied thermal expansion coefficient in the thickness direction. The surface of the cooling pipe 18 is made in a rough surface in order to improve the biting of the graphite flakes and the binder without hurting the heat conduction.

Abstract: PURPOSE:To enhance the recording stability by forming a toner image of uniform density by a method wherein rigidity of each part of a vibrating body provided to an image forming device is regulated so that the whole of the vibrating body can be uniformly vibrated. CONSTITUTION:An aperture electrode 20 bonded to a part other than a slit 41 of a vibrating body 42 is vibrated as it is while following the vibrating body 42. The aperture electrode 20 in the slit part 41 is vibrated by taking both end parts in a width direction of the slit 41 as an exciting part. Then, when the aperture electrode 20 is excited with the vibrating body 42, a beat of vibration is formed at each part of (a), (b), and (c) as a distribution of the vibration, and uneveness is generated in recording density. However, by applying hardening to a slant line part of the vibrating body 42 which is opposed to the part of the aperture electrode 20 wherein the vibration beat is formed, the vibration occurring in the slant line part can be restrained. An elastic body consisting of metals such as aluminum, stainless steel, etc., are used for the vibrating body 42.

IPC: A23L29/20
Filed: 1978-10-05
Abstract: PURPOSE: A high-temperature liquid ingredient that becomes fluid at high temperaures, solidifies at low temperaures and can keep the shape at temperatures over 0°C, and small pieces of another low-temperature solid ingredient are mixed in a vessel, sealed tightly and solidified by cooling, thus giving cakes with sophisticated taste.  
     CONSTITUTION: A high-temperature liquid of an ingredient that becomes fluid at high temperatures, solidifies at low temperatures and keeps the shape at temperature over 0°C, such as high-temperature jelly of soft azuki bean mainly consisting of agar, bean jam and water, and small pieces of another low-temperature solidifying ingredient such as small pieces of agar, are charged in to a vessel, closed tightly, and cooled. At this time, the small pieces of the solidifying ingredient softens and dissolves in the high-temperature liquid to bind with each other. However, the soft azuki jam jelly and the agar pieces do not mix to homogenize. The high-temperature liquid gradually becomes cool and solidifies to integrate with the agar pieces, thus giving novel type of cake with sophisticated taste, which has not been given by either existing bean jam jelly or agar.

Title: Controller for ac elevator
Inventor: IKEJIMA HIROYUKI
IPC: B66B1/30
Filed: 1985-06-06
Abstract: PURPOSE:To make it possible to process reactive power without smoothing condenser by connecting a resistor and a transistor in series with the DC side of a converter. CONSTITUTION:A resistor 16 and a transistor 17 are connected in series with the DC side of a converter 3. When a reactive power is generated in a motor 6 and the voltage of the DC side of the converter 3 becomes the prescribed value by the reactive power, a reactive power controller 18 operates to conduct the transistor 17 and to control the conducting time. Thus, the reactive power is consumed by the resistor 15. Accordingly, the smoothing condenser 4 of the conventional device can be eliminated to obviate a danger of electric shock and to prevent the power factor of a power source side from decreasing.
