Title: Natural-circulation system boiling water reactor
Inventor: KOJIMA AKIRA
IPC: G21C15/26
Filed: 1987-12-08
Abstract: PURPOSE:To decrease the probability of a loss of coolant by providing a control rod driving means which drives a control rod from above and a steam drying unit which is connected with a main steam piping, dries formed steam and guides the steam to the main steam piping. CONSTITUTION:The water separated from the steam in a reactor pressure vessel 1 flaws down from the upper part of a chimney 9 in a downcomer section 30 enclosed by the chimney 9 and the vessel 1 to the lower part of a reactor core 3, from which the water is introduced again to the reactor core 3. The water separated by a steam dryer 19 in the steam drying unit 15 is guided to the lower part of a unit vessel 17 via a drain piping and is returned through a return pipe 23 to the vessel 1. The core 3 is inserted with the control rod 7 by the control rod driving mechanism 13 disposed in the upper part 1 in the vessel 1 and is thereby controlled; therefore, there is no need for providing a hole for insertion of the driving mechanism 13 in the bottom of the vessel 1. The loss of the coolant from the control rod insertion hole is thereby obviated and the safety of the reactor is improved.

Title: Optical scanner
Inventor: ENDO MICHIHIKO
IPC: B41J2/44
Filed: 1999-10-29
Abstract: PROBLEM TO BE SOLVED: To obtain an angle adjustment mechanism for reflection mirror simple in configuration, attachable even in a narrow space and easy to access an adjustment screw. SOLUTION: When the adjustment screws 48A and 48B are rotated from the upper part of an optical box 62 by a driver and the like, plate walls 32A and 32B are elastically deformed together with receiving plates 46A and 46B and the reflection mirrors 74A and 74B are pressed by action parts 34A and 34B to adjust the angle. Since the mirrors 74A and 74B are not directly pressed by the screws 48A and 48B, the latitude of setting the position of the adjustment screw is increased. Since the plates 46A and 46B are positioned at positions outwardly apart from the longitudinal-direction end parts of the reflection mirrors, there is no possibility of damaging a reflection surface due to that the screws 48A and 48B are brought into contact with the surface when the angle is adjusted, and also the adjustment screw, can easily accessed to facilitate the adjustment work.

IPC: H03M13/23
Filed: 1988-12-07
Abstract: PURPOSE:To improve the accuracy of transmission information data decoding by decoding optimizingly a desired estimate error series while taking it into account that all transmission information series cannot be regarded to be probable equally and the apparent transmission information data series and line noise are not mutually independent. CONSTITUTION:In a 2nd decoder 170 to decode an estimate error of a simple decoding No.130, a conventional Viterbi decoding method is not used but the MAP estimate method being a start point of the most likelihood decoding method is turned back, all the likelihood calculation is retried from the standpoint of applying most likelihood processing to 'mu(x)mu(zlx)' newly to obtain a distance function, the most likelihood is obtained to decode an estimate error. Since the branch likelihood able to attain optimizing decoding to a desired estimate error by a main decoder 170, that is, the distance function is obtained in this way, the estimate error with high accuracy is obtained and the accuracy of a decoded data is improved.

Title: Semiconductor device
Inventor: TSUDA HIROSHI
IPC: H01L21/301
Filed: 1986-12-26
Abstract: PURPOSE:To play an important role in visual improvement, dust prevention and yield increase by a method wherein multiple insulating films near scribe lines are patterned on respectively different lines. CONSTITUTION:A silicon oxide film 2 formed on a silicon substrate 1 is dryetched to form a steep step difference 3 on a scribe line side. Next, a titanium layer 4, a platinum layer 5 and a gold layer 6 are formed successively covering the step difference 3. When any needless metals excluding an electrode part are removed by anisotropical etching technology such as dryetching process using a photoresist 9 taking an electrode shape as a mask, a titanium platinum residue 7 is left on the step difference part 3. When a silicon oxide film 8 is grown to be patterned on the scribe line side, the titanium can be etched even if it is subjected to etching process preventing the platinum from peeling off. Through these procedures, any metallic residue can be prevented from peeling off having notable effect on visual improvement, dust prevention and yield increase.

Filed: 1993-12-10
Abstract: PURPOSE:To use exact values of motor current for the improvement of motor control and prevent torque ripples, by correcting error components (offset value/ non-linear error) contained in the current detector of a motor control equipment. CONSTITUTION:Alternating current power 1 is supplied to an a.c. motor 6 through a power converter, and motor speed omegar and currents Iu, Iv, Iw are fed back from a speed detector 8 and a current detector 7, respectively. An inverter 5 is thereby PWM-controlled to control the motor. Components of offset value/ non-linear error, contained in the current detected by the current detector 7, are removed at a current corrector 9. The current corrector 9 is provided with a low-pass filter for which a time constant is set according to the cycle of alternating current during the ordinary operation of the motor. The corrector 9 thus detects and removes offset values. An ordinary operation is judged from primary angle frequency command omega1* and the width of fluctuation in speed omegar.
