Title: Reactivity control of light water cooled and light water moderated nuclear reactor core
Inventor: KOMANO YASUO
IPC: G21C7/00
Filed: 1988-05-27
Abstract: PURPOSE:To suppress an output peaking to a low level, by substituting effluents in a plurality of substitutable regions at a high temperatured core condition, with light water, heavy water, boric acid water or other effluents, correspondingly to a reactor core conditions. CONSTITUTION:Prior to a start up, all substituting pipes 14 in 8 regions are filled with boric acid water. Afterward, a lid of a reactor vessel 22 is placed and a primary coolant is heated up, and when a hot shutdown condition is attained, valves V16 and V2, connected to a substitutable region D, are opened to transfer the boric acid water to a boric acid tank 26. In this process, water in the substituting pipes 14 falls down by flushing and a water head difference. Then a valve V6 is opened and a heavy water feed pump 30 is actuated to inject heavy water into the substituting pipes 14 and to substitute boric water in substitutable regions C, B2, B1 and A4, with heavy water. From this situation, control rods are withdrawn to increase an output and a reactivity decrement resulting from a Xenon storage is compensated by substitution of the boric acid water in the substitutable regions A3, A2 and A1 with heavy water. With this procedures, a reactivity control can be executed without any addition of control rods.

IPC: H04N21/2368
Filed: 1996-05-24
Abstract: PROBLEM TO BE SOLVED: To verify the multiplexing schedule of a multiplexed stream without actually decoding. SOLUTION: A preprocessing part 2 extracts access unit information from an elementary stream. A scheduler 4 decides the schedule of time division multiplexing based on access unit information supplied through a storage medium from the preprocessing part 2. A multiplexed data generation processing means 5 generates a multiplexed steam based on the elementary stream, access unit information and schedule information. At this time verifying processing part 8 can simulate the transition of a buffer occupying quantity based on access unit information and schedule information without processing the generated multiplexed stream.

Title: Control method and controller for multiple robot system
Inventor: HASHIMOTO YOSHIKI
IPC: G05B19/18
Filed: 1993-05-07
Abstract: PURPOSE:To simplify the robot disconnecting/releasing operation of the multiple robot control system and to prevent falling. CONSTITUTION:When disconnection buttons (SB#1/#2) of a control panel 15 are pressed, CR1#1 and CR1#2 are immediately opened. Once CR2#1 and CR2#2 are closed and brake mechanisms of RB#1 and RB#2 are made 'effective'. Then CR3#1 is opened a specific time later to disconnect the servo electric power of a corresponding robot. To make the robot return, CR1#1 and CR1#2 and CR3#1 and CR3#2 are closed by pressing buttons CB#1 and CB#2 to connect the servo power source. Then CR2#1 and CR2#2 are closed for a specific time later to reset the brake mechanism of the corresponding robot, thereby resetting the robot from the disconnection state to the connection state. The operation for disconnection and resetting is easy and servo driving power is ceased in neither switching states while the brake mechanism is ineffective, so the falling accident of a robot arm is prevented.

Title: Measuring method for distribution of impurity concentration
Inventor: HIROFUJI YUICHI
IPC: H01J37/252
Filed: 1987-05-27
Abstract: PURPOSE:To measure the impurity concentration at a part corresponding to the depth of a recessed part, by observing the time-wise variation of ion quantity corresponding to the impurity in secondary ion while etching rate is kept constant. CONSTITUTION:In the inside of a groove 3, a polycrystal Si film is deposited, by, e.g., LPCVD method. After that, a part containing a region (a) is irradiated by Cs<+> ion as primary ion, and As<-> ion is detected out of secondary ion emitted from a part corresponding to the region (a). At first, the polycrystal Si only is etched, and As is not contained. When the etching reaches the surface AA' of a silicon substrate surface, a signal of As begins to be detected. In the case where the impurity concentration and the etching rate are constant in the following region, the quantity of ion species corresponding to the impurity contained in the output secondary ion is proportional to the impurity quantity in each surface. The above-mensioned region is the inner side surfaces of all grooves and holes corresponding to the depth from aperture parts of recessed parts in the region to be ethed, e.g., grooves and holes. Therefore, if the impurity concentration in the vicinity of apertures of grooves and holes is known, the quantity of impurity in the inner side surfaces can be easily derived.

IPC: H04N1/04
Filed: 1990-05-21
Abstract: PURPOSE:To surely recognize even a mark position marked imperfectly by storing mark data read during a period that the synchronizing mark of either a left side or a right side exists. CONSTITUTION:When the synchronizing mark 9a, 9b of either the left side or the right side is detected by a reading part 3, the data of a buffer memory 5a is written in a storage memory 5b, and a control circuit 1 stores the data of a mark sheet 9 read during the period that the synchronizing mark 9a, 9b of either the left side or the right side is detected in the storage memory 5b, and when the synchronizing mark 9a, 9b comes not to be detected, the control circuit 1 recognizes the mark position by checking the data of the storage memory 5b. As the result, when the mark position is recognized, the control circuit 1 discriminates the data corresponding to the recognized mark on the basis of a data table set beforehand in a program memory 2, and writes it in a data memory 5c, and it recognizes the marks between the synchronizing marks 9a and 9b one after another. Thus, the mark can be surely recognized.

Filed: 1990-05-21
Abstract: PURPOSE:To diminish the tape winding diameter and to miniaturize a recording and reproducing device by enlarging a mouth part at the time of use and making energizing force by springs to tape reels approximately the same before and after the tape reels are moved. CONSTITUTION:Under the normal state, the tape reels 4 and 5 are in positions where a general standardized tape cassette is interchangeable, and consequently the size of the mouth part 12 is not so large. At the time of using, by rotating the tape reels 4 and 5 to be retreated to a rear corner part in the cassette case 1, the mouth part 12 is drastically enlarged, and hence a head drum, etc., can be inserted further into the interior of the cassette case 1 to be put completely in the mouth part 12. By this method, the recording and reproducing device can be miniaturized. Moreover, since the energizing force by the springs 16 and 17 to the tape reels 4 and 5 is approximately the same before and after the tape reels 4 and 5 are moved, the rotation of the tape reels 4 and 5 can be stabilized.
