Title: Vibration decreasing construction of lower plenum structure of nuclear reactor
Inventor: FUKUDA SHINICHI
IPC: G21C15/243
Filed: 1989-07-18
Abstract: PURPOSE:To decrease the vibration in the lower plenum structure of the core by the disturbance in the flow of coolant passing in reactor water flow passages by installing shroud legs at the intermediate points of adjacent internal pumps. CONSTITUTION:The shroud legs 20 are installed at the intermediate points of the adjacent internal pumps 5 so that the reactor water flow passages 21a, 21b are not formed at the intermediate points of the adjacent internal pumps 5. The flow of the coolant is disturbed at the intermediate of the pumps 5 by the collision of the coolant discharged from the respective pumps 5 against each other and is thereby changed in course by 90 deg., but the shroud legs 20 exist in the changed course and the coolant cannot advance. The stagnation of the coolant is thus generated. The flow spreading to the overall height of the reactor water flow passage is changed to the flow along the end plate in the lower part of the reactor pressure vessel during this time. The large vibration that the turbulent flow by the collision of the coolant against each other imparts by colliding against a housing 9 of a control rod driving mechanism and a neutron flux monitor housing 10 is, therefore, prevented.

Title: Developing method
Inventor: SUEMITSU YUJI
IPC: G03G13/08
Filed: 1984-09-04
Abstract: PURPOSE:To obtain a high quality developed image prevented from secular change and environmental change by holding a conductive developer on a carrier as a single layer and carrying the developer to a developing area under the state that the developer is not brought into contact with an electrostatic latent image carrier or an electrode to lead the charge whose polarity is reversing to that of the electrostatic latent image. CONSTITUTION:Electrostatic images are formed on a latent image carrier 1 and a developer 8 is held on a developer carrier 5 as an approximately single layer and carried to a developing area. A gap to keep a developer layer 4 at the uncontacted status with the latent image carrier 1 is formed between the latent image carrier 1 and the developer carrier 5. The charge whose polarity is reversing to that of the electrostatic latent image is led under an electric field formed between the carries 1 and 5 and the developer 8 is transferred only to a picture part to end the developing process. Consequently, the developed pictures can be prevented from disturbance, the generation of fog, uneven density, and secular change environmental change.

Title: Electronic engine controller
Inventor: YAMAMOTO AKITO
IPC: H03M1/12
Filed: 1980-12-26
Abstract: PURPOSE:To achieve secure A/D conversion in any case by performing either one of the 1st A/D conversion and 2nd A/D conversion when a request for the 2nd A/D conversion is made during the 1st A/D conversion while the operation state of an A/D converter is monitored by an FF circuit. CONSTITUTION:If an interruption request signal is generated synchronizing with the prescribed period of an aperiodic timer while an A/D converter 6 performs A/D conversion, a microcomputer 1 judges that the converter 6 is in operation since an A/D-conversion start signal ADS raises on a signal line 10, and then stores a channel signal which corresponds to the interruption signal in a memory RAM. Once the 1st A/D conversion ends, the converter 6 supplies a request signal EIS for conversion-end interruption to the computer 1 through a signal line 12, a control circuit 8 and a signal line 14 to execute an interruption program. At this time, a conversion end signal CES is supplied to the reset terminal of an FF21 through the signal line 12, so the Q output of the FF21 falls down to a 0.

Title: Chipping-resistant coating
Inventor: IKEDAIRA AKIO
IPC: C09D127/04
Filed: 1987-07-23
Abstract: PURPOSE:To make it possible to protect a substrate by preventing the film from being damaged by a shock, by forming hollow cells in a film after baking by adding a blowing agent for forming a specified amount of voids in a formed film of a vinyl chloride sol coating. CONSTITUTION:A vinyl chloride sol chipping-resistant coating containing a blowing agent in an amount to form 1-60vol.% voids in a formed film. The structural elements of the chipping-resistant coating consist of a vinyl chloride sol or a vinyl chloride organosol containing a small amount of a solvent (vinyl chloride sol) as the main component. When the volume of said voids is below 1vol.%, the film cannot absorb a shock of, e.g., a hit stone because of its excessively low content of voids, and when it is above 60vol.%, the film decreases in strength because of its excessively high content of voids. In both cases, the chipping resistance is decreased and no effect is attained.
