Title: Radio communication system
Inventor: ITO KOICHI
IPC: H04W76/00
Filed: 1987-03-20
Abstract: PURPOSE:To quickly avoid the state that an outgoing/incoming is impossible, due to an interference from a neighboring radio communication equipment by detecting the occurrence of the interference and an obstruction from other radio communication device, on the basis that a received electric field intensity, stronger than a prescribed value, in a control channel, continues longer than a prescribed time. CONSTITUTION:In case that a master device 1 or a radiotelephony equipment 2 uses the control channel actually, the time of use is limited within the prescribed time, and besides, during the time of use, the information such as an ID code or the like is certainly modulated. Using this fact, if it is detected by detecting means 10, 20, 47, 48 that the received electric field intensity in the control channel is stronger than the prescribed value, and further, the receiving time continues longer than the prescribed time, the interference and the obstruction are recognized to be present, and it is reported to an operator, for instance. Accordingly, if the operator moves to a position, where the interference and the obstruction are not present, at this report, the state that the outgoing/incoming is impossible is avoided, and the normal outgoing/incoming is performed.

Title: Semiconductor device and manufacture thereof
Inventor: YO SHOJI
IPC: H01L23/52
Filed: 1999-03-12
Abstract: PROBLEM TO BE SOLVED: To reduce the effect on a data retention time and transistor characteristics, by allowing a silicon oxide film formed on a semiconductor substrate to comprise a laminating structure of first and second silicon films, and allowing difference between impurity concentrations introduced into the first and second silicon films. SOLUTION: A storage node electrode comprising first and second silicon films 51 and 53, a capacitor insulating film 57 of a nitride film, and a cell plate electrode 59 comprising a silicon film, are provided. The first silicon film 51 is not introduced with an impurity, or introduced with such impurity of a concentration lower than the impurity concentration introduced into the second silicon film 53, while the impurity of high concentration is introduced into the second silicon film 53. Since the impurity concentration introduced into the second silicon film 53 is higher than the first silicon film 51, the impurity introduced into the second silicon film 53 is suppressed not to transfer to a diffusion layer 3 in a thermal process after formation of a storage node electrode.

IPC: B21C37/08
Filed: 1980-05-20
Abstract: PURPOSE: To manufacture a multilayer steel pipe with weld zones of high strength and reliability, by previously applying a buttering welding to both broadside edges.  
     CONSTITUTION: Plural steel sheets 3W7 are piled up, and the broadside edges 3AW7A and longitudinal edges 3BW7B are arranged; the sheets 3W7 are pressed by a press machine 8 in the direction of thickness so as to tight contact with each other. The press machine 8 clamps and fixes the sheets 3W7 between its bottom plate 10 and bolts 13. While covering the broadside edges 3AW7A with a flux, a buttering welding is applied to the broadside edges 3AW7A by a welder 16. After finishing this buttering welding for the broadside edges 3AW7A on one side, another side is also applied a buttering welding; or otherwise, the buttering welding is applied to both broadside edges 3AW7A, 3AW7A at the same time. A chamfering work is applied to the buttering welded broadside edges; then, the sheets 3W7 are bent in the direction of breadth so as make both broadside edges butt to each other; hereby, a groove is formed by the chamfered edges; a welding is then applied to this groove for welding both broadside edges 3AW7A, 3AW7A to each other.

Title: Automatic color control circuit
Inventor: OGUMA HIROSHI
IPC: H04N9/68
Filed: 1986-03-25
Abstract: PURPOSE:To obtain a compensation output of a chrominance carrier signal with high accuracy and a small circuit scale by using a difference of a burst between a burst signal in an input chrominance carrier signal and a burst value smoothed before so as to smooth the input burst. CONSTITUTION:A burst detector 4 detects a peak value (burst value) of a burst signal included in a chrominance carrier signal inputted to a terminal 1 at each horizontal period one after another, a burst value smoothed before is subtracted by a subtracter 18, and the result is multiplied by 1/K at a 1/K multiplier 19. The signal subjected to 1/K multiple is added to the burst value smoothed before by an adder 20 and the result is inputted to a divider 13 and a latch 21 as an output of a smoothing circuit 17. The divider 13 outputs a value being the division of the reference burst by the smoothed burst value when the smoothed burst is a prescribed threshold value or over, and outputs '0' if the burst value is less than the prescribed threshold value. The output of the divider is multiplied with the chrominance carrier signal at a multiplier 15 and the chrominance carrier signal output subject to amplitude compensation with high accuracy is obtained at an output terminal 16.

Abstract: PURPOSE:To prevent the thermal distortion of a reflecting mirror, to raise control precision simultaneously, and to reduce power consumption by constituting a driver to drive the reflecting mirror of an coil fixed to the machine frame of a carriage and a permanent magnet fixed to the reflecting mirror, and in addition, providing the permanent magnet with a magnetic circuit. CONSTITUTION:The reflecting mirror 3 to control a light spot in the radial direction of the medium of the optical disk device is attached movably to the machine frame 1 of the carriage. The driving device 4 to drive the reflecting mirror 3 is constituted of the coil 41 fitted fixedly to the machine frame 1 and the permanent magnet 42 fixed to the reflecting mirror 3 and magnetized in a direction perpendicular to the axis of the coil 41 fixed to the reflecting mirror 3. Besides, the permanent magnet 42 is provided with the magnetic circuit 43 to guide magnetic flux from its pole of one side to its pole of the other side. Since the magnetic flux of the permanent magnet 42 flows from the pole of one side to the pole of the other side as being guided by the magnetic circuit 43, the magnetic flux can be prevented from expanding to its vicinity, and besides, since the coil 41 is not fixed to the reflecting mirror 3, the generated heat of the coil 41 is never transmitted to the reflecting mirror 3, and the thermal distortion of the reflecting mirror 3 can be prevented.

Title: Treatment of excretion
Inventor: IWASAKI MAKOTO
IPC: C02F3/34
Filed: 1984-04-07
Abstract: PURPOSE:To perform denitrification with high efficiency by supplementing the lowering of a BOD/NH4-N ratio, by performing the denitrification treatment of the liquid component obtained by the flocculation treatment of raw excretion while intermittently varing the pH of said liquid component between 7.5 and 8.6 in a denitrification tank receiving a nitrated solution and return sludge. CONSTITUTION:Nitration bacteria in the sludge returned to a denitrification tank 2 and the sludge in the recirculated nitrated solution 9 coming from a nitration tank 3 are contacted with high concn. free NH3 in the dentrification tank 2 to receive selective inhibiting action and lowered in its activity whereas the activity of nitrite bacteria is not changed. Sludge containing nitrite bacteria not lowered in its activity is moved to the nitration tank 3 of the next process and NH4<+> is oxidized herein by the action of nitrite bacteria to form NO2<->. Because the action of nitrite bacteria is lowered, the greater part of NOx-N is recirculated to the denitrification tank 2 in a form of NO2-N and NOx-N can be reduced in a BOD amount low as compared with a nitrate form in the denitrification tank 2.
