Title: Method for curing epoxy resin having excellent heat resistance and cured epoxy resin product
Inventor: YAMAMOTO HISANAO
IPC: C08G59/24
Filed: 1996-02-23
Abstract: PROBLEM TO BE SOLVED: To obtain a cured epoxy resin produce excellent in heat resistance and toughness by curing a curable resin composition comprising a specified epoxy resin and a curing agent at a specified temperature. SOLUTION: A thermosetting resin composition comprising an epoxy resin represented by formula I (wherein A is a group represented by formula II; and (n) is an integer of 0 or greater) and having a melting point of 170 deg.C or above and a curing agent is cured at a temperature equal to or lower than the melting point of the epoxy resin. Because there is recently a tendency to use a cured epoxy resin product under severer conditions, it sometimes happens that the product lacks in heat, impact and moisture absorption resistances, etc. The above epoxy resin has biphenyl groups as a mesogenic group having a rigid skeleton and has a degree of polymerization of at least a specified value.  By mixing, therefore, this resin with a curing agent and curing the obtained mixture at the above-mentioned temperature, a cured epoxy resin product excellent in both heat resistance and toughness can be obtained.

Title: Laser annealing apparatus
Inventor: SASAKI NOBUO
IPC: H01L21/20
Filed: 1986-03-18
Abstract: PURPOSE:To prevent an optical axis from varying and the output of a laser from decreasing disposing an X stage directly under a heater, and disposing a Y stage under the X stage and a rotating unit in the lowermost position to reduce an impact due to the acceleration or deceleration of the high speed stage. CONSTITUTION:An X stage 26 is placed directly under a heater 22, a Y stage is disposed under the stage 26, and a rotating unit is disposed in the lowermost stage. Thus, the load of the high speed stage 26 is reduced to decrease an impact due to acceleration or deceleration, thereby reducing an influence to a laser unit and an optical system. That is, when the high speed stage is placed at an upper position, the load of the high speed stage is reduced, and a mechanical strength may be reduced, but since the accurate stage placed at a lower position is increased at its load, it must be rigid and increased in size to increase the weight as a whole, but the load of the high speed X stage is only the heater to reduce the acceleration between back and forth reciprocations. When the rotating unit 28 is disposed at the lowermost stage, a wafer 20 can be rotated at the optical axis as a center by matching the rotating center to the optical axis of a lens 18 to rotate the wafer 20 at the optical axis as a center, thereby facilitating the operation such as matching of the side and the scanning direction of a region to be processed.

Abstract: PURPOSE:To simplify the structure by making a feed roller into a semi-circular form, and providing a one-rotation spring clutch for controlling on/off of a clutch every rotation on a driving force transmitting means. CONSTITUTION:Two semi-circular feed roller 53 (53A and 53B) is installed to a paper feed shaft 52 in such a manner as to rotate integrally, and a concentric and circular free rotating roller 64 is rotatably fitted thereto. The outer diameter of the free rotating roller 64 is selected to a size slightly smaller than the feed surface outer diameter of the feed roller 53A and larger than the notch part of the feed roller. The rotation of an input gear is transmitted to a gear (clutch gear) 74 on the paper feed shaft 52, and a rotating spring clutch 75 is provided between the gear 74 and the paper feed shaft 52. Thus, paper feed operation is terminated by one rotation of the feed roller 53.

Title: Method for controlling waterwheel
Inventor: HAYAKAWA KEIZOU
IPC: F03B15/04
Filed: 1979-05-17
Abstract: PURPOSE: To prevent the rotary part from floating safely and easily by the method wherein, in cutting off the load of a waterwheel or stopping it, the guide vane opening is maintained at the required opening below the no-load opening until the rotational speed of the waterwheel becomes below the rotational speed to cause floating.  
     CONSTITUTION: In cutting off the load of a waterwheel or stopping it, when guide vane 4 is closed, the rotary part rotates by its inherent rotational energy, and thereby the waterwheel is caused to operate reverse pumping. Due to the pressure difference between the upper and the lower side of runner vane 1, pushing-up force F 1  is produced, and this is combined with pushing-up force F 2  due to water level 3 of discharge channel 2 to attain a force to push up the rotary part. Since pushing- up force F 1  is proportional to the square of the rotational speed, guide vane 4 is not totally closed until the rotational speed of the waterwheel becomes below rotational speed N 0  to cause floating, and control is operated in accordance with the block diagram so as to maintain its required opening A 0  below the no-load opening. Accordingly, it is possible to prevent the rotary part from floating safely and easily.
