Title: Output adjusting device for nuclear reactor
Inventor: ISHIGURO AKIHIRO
IPC: G21C7/28
Filed: 1990-03-30
Abstract: PURPOSE:To stop the nuclear reactor in emergency and to secure the safety by releasing rotary motion which is transmitted to a pinion by a clutch in case of emergency and falling a reflecting body naturally. CONSTITUTION:When the operation of the nuclear reactor is started and a driving motor 9 is driven as fuel 2 is burnt, a pinion 6 which engages a rack 5 through a speed reducer 10 and the clutch 11 rotates and the reflection body 3 is elevated along a guide shaft 7. If abnormality occurs to the nuclear reactor or relative system during the operation, a clutch control part 12 sends an opening signal automatically to the clutch 6 to release the transmission of the rotary driving force to the pinion 6, so the pinion 6 becomes free to fall together with the reflection body 3 while engaging with the rack 5, thereby stopping the operation of the nuclear reactor urgently. If the clutch 11 does not operate owing to a fault, the clutch 11 is released automatically and a mechanism which releases the clutch 11 mechanically is also provided, so the reflection body 3 is securely fallen to stop the operation of the nuclear reactor.

Title: Crystal growing device
Inventor: ITOU KAZUHIRO
IPC: H01L21/208
Filed: 1982-05-21
Abstract: PURPOSE:To prevent the crystallization of polycrystals in the periphery of a substrate holding part by a method wherein the thermal conductivity in the periphery of the substrate holding part is made lower than that of the flat part which contacts the substrate. CONSTITUTION:A part 26 which constitutes a recess 23 is provided on the lower part 24 of a crystal growing device, and a substrate 22 is placed on the recess 23. Then, a growing layer 27 is formed on the substrate 22 by accumulating solution 21 in the upper part 25 of the crystal growing device. Where, the part 26 has a low thermal conductivity, or is so prepared that the thermal conductivity becomes low between the lower part 24 of the device. Therefore, even when there is a temperature gradient that the temperature decreases from the solution 21 to the direction of the substrate 22, the thermal flow selectively flows to the substrate 22, as shown by dot lines in the figure, by the presence of the part 26, and accordingly the diffusion of solute in the solution 21 is performed also selectively to the substrate 22.

Abstract: PURPOSE:To obtain the titled compound useful in a plastic field in a short time in high yield industrially advantageously, by adding a specific aromatic sulfonic acid to a reaction system and reacting dehydrating phenol with a sulfonating agent, etc. CONSTITUTION:Phenol is reacted with a sulfonating agent (e.g., conc. sulfuric acid, sulfuric anhydride, etc.) or phenolsulfonic acid to give dehydroxydiphenolsulfone. In the operation, an aromatic sulfonic acid shown by the formula (X is halogen; n is 0, 1, or 2; m is 1 or 2) is added to the reaction system to carry out the reaction. Benzenesulfonic acid, chlorobenzene-4- sulfonic acid, chlorobenzene-2-sulfonic acid, etc. may be cited as the compound shown by the formula. The existence of the compound shown by the formula promotes the reaction and the reaction can be carried out at relatively low temperature (usually 120-220 deg.C, preferably 140-200 deg.C) so this method can advantageously suppress by-products.

Filed: 1994-04-22
Abstract: PURPOSE:To prevent noises from being erroneously detected because of clutters, etc., by determining a threshold level by a calculated value of a standard deviation of noises. CONSTITUTION:The noise level of output of a reference cell in a shift register circuit 4 which is input to a noise level-operating circuit 5 is calculated and input to a variable threshold level-operating circuit 8 and a noise standard deviation-operating circuit 6. The circuit 6 calculates standard deviation sigma of noises from the output of the reference cell and an output value of the noise level NL of the circuit 5, and inputs the deviation to the circuit 8. A deviation constant-generating circuit 7 generates a deviation constant alpha. The circuit 8 calculates a threshold level TH2 from the noise level NL, standard deviation sigmaand deviation constant alpha. The threshold level TH2 calculated by the circuit 8 is input to a comparator 9, where it is compared with an amplitude S of the output signal of the circuit 4 input similarly to the comparator 9. When the amplitude S is larger than the output signal of the circuit 8, the comparator 9 outputs '1'.

Title: Bathtub water level detecting method
Inventor: NOGUCHI YUKINOBU
IPC: F24H1/46
Filed: 1996-04-08
Abstract: PROBLEM TO BE SOLVED: To accurately measure the water levels by assuming the detecting state according to a difference between output values of a pressure sensor before and after a circulation operation and a difference between output value previously detected at a proper detecting state where air is not introduced into a circulation path and output value after air is introduced into the circulation path. SOLUTION: An output value of a pressure sensor 23 is obtained before a circulation operation. Then, a pump is operated to circulate water in a bathtub 18 through a circulation path 12 and an output value of the pressure sensor 23 during the circulation operation is obtained. A difference between the output values of the sensor 23 before and during the circulation operation is calculated. The calculated output difference is compared with an output difference between an output value previously detected at a proper detecting state where air is not introduced in the circulation path 12 and an output value after air is introduced into the circulation path 12.  If the output difference is within an error range in measurement, the output value during the circulation operation is assumed to be the output value at the proper detecting state and the water level is calculated from the output value.
