Title: Digital automatic gain control system
Inventor: MURATA HIROYASU
IPC: H03G3/30
Filed: 1989-11-10
Abstract: PURPOSE:To increase the time constant of the AGC by determining the amplification factor for a succeeding period depending on an output of a tendency analysis circuit. CONSTITUTION:A tendency analysis circuit 4 stores n-set of peaks of waves of an error signal (s) and grasps the tendency of a level of an input signal X at a current point of time to discriminates whether or not the signal is to be amplified or compressed. Then the circuit 4 outputs the result to an amplification factor adjustment circuit 2, a 1st means amplifies a signal for n-set of waves from a succeeding wave peak from the result and a 2nd means amplifies a signal by a peak of a succeeding wave. Thus, the number (n) is increased more, at a wider range the tendency of the level of the wave is grasped and then number of times of information returning to the amplification factor adjustment circuit 2 is less, thus the time constant is increased and even when bit accuracy of alpha is small, a larger time constant is obtained by increasing the (n) sufficiently.

Title: Antioxidant control of exudative mercury in fluorescent lamp
Inventor: HAITKO DEBORAH ANN
IPC: H01J61/26
Filed: 1997-10-27
Abstract: PROBLEM TO BE SOLVED: To significantly reduce or prevent the forming of an exudative mercurous and mercuric compounds due to oxidization of an element state mercury by introducing an inorganic or an organic antioxidant into a fluorescent or low-pressure mercury arc lamp. SOLUTION: When an antioxidant is introduced into a lamp structure or toxic exudative characteristics method testing solution, an ion or copper metal part is prevented from being oxidized to an oxidization form being soluble and having oxidization capability to a soluble oxidization mercury of an element state mercury. Therefore, production and dissolution of a soluble ferric and a cuprous compounds from a lamp part is decreased or prevented, and as a result, an exudative mercury compound is reduced and prevented. The antioxidant is selected from among groups consisting of an element-state iron, an ascorbic acid and an ascorbic acid sodium. Use of the ascorbic acid is preferable.

Abstract: PURPOSE:To improve the nuclear hydrothermal force stability of a fuel assembly with minimum spring chamber length by inserting a volute spring into a spring chamber of less than specific length formed among a canning pipe, an upper end plug and the upper end of packed fuel pellets, the volute spring being in contact with the center of the lower surface of the upper end plug. CONSTITUTION:A fuel rod 14 has a long, hollow canning pipe 44, the upper and lower ends of the fuel rod 14 being closed with upper 46 and lower 48 end plugs, respectively. Fuel pellets 50 are packed in the canning pipe 44. A volute spring 56 is disposed inside a spring chamber 55 located at the upper end of the pellets 50 to bring the pellets 50 into surface contact with one another, the narrow end of the spring 56 being in contact with the center of the lower surface of the end plug 46 and the thick end of the spring 56 being in contact with a flat disc 58. The spring 56 provides a great compressive force with a small amount of deflection and can reduce the length of the spring chamber 55 to about 10cm or less. Therefore, the nuclear hydrothermal force stability of the fuel assembly can also be enhanced to a large extent.

Title: Magnetic type eccentricity measuring apparatus
Inventor: YOSHIDA MITSUO
IPC: G01B7/312
Filed: 1986-12-09
Abstract: PURPOSE:To enable on-line monitoring handily with a high measuring accuracy, by using a system which is adapted to make an excited magnetic field rotate electrically utilizing electromagnetic effect. CONSTITUTION:A 3-phase AC from a 3-phase AC generator 2 is applied to a rotary magnetic field generator 1 through phase amplifiers 5a-5c. A magnetic detection sensor 15 arranged on the inner wall of the generator 1 detects changes in the magnetic flux in the radial direction of material to be inspected passed through the flux. One end of the sensor 15 is earthed while the other end thereof is connected to an amplifier 6 to cancel the residual output of the generator 1 with a zero adjustment circuit 7, provided that it is turned to a noise without the material being inspected. An output of a single-phase AC oscillator 8 phase shifted 9 is used as reference wave to phase detect 3 outputs produced subsequently. This enables non-contact measurement of the material to be inspected in a fast rotatable rotary magnetic field with the sensor 15 and hence, permits handy building of an apparatus which ensures a high accuracy regardless of fast movement of the material being inspected along the length thereof thereby achieving a higher flaw detection accuracy on-line.

Title: Lighting device for fluorescent lamp
Inventor: YASUDA TAKEO
IPC: F21V25/00
Filed: 1990-10-31
Abstract: PURPOSE:To make a fluorescent lamp correspond to only conforming frequencies by providing either fluorescent lamp devices or lamp lighting fixtures with protrusions corresponding to the conforming frequencies and separate from the axis of rotation of a base by a different distance, and also providing the other with reception channels which fit with only respective protrusions and which can be turned. CONSTITUTION:To mount a fluorescent lamp device 100 for 50Hz in a lighting fixture 150 used exclusively for 50Hz, a protrusion 120 provided on the device 100 is inserted into a reception channel 130 provided in the lighting fixture 150 and a base 7 is inserted into a socket 40 and rotated and the base 7 is threadably inserted therein. Even when a user intends to mount a fluorescent lamp device 200 for 60Hz in the lighting fixture 150, a protrusion 220 provided on the device 200 cannot be inserted into the reception channel 130 and so it is impossible for the device 200 to be connected to a commercial power source 160 of 50Hz. To mount the device 200 in a lighting fixture 250 used exclusively for 60Hz, the protrusion 200 provided on the device 20 is inserted into a reception channel 240 provided the lighting fixture 250 and the base 7 is inserted into the socket 40 and rotated and the device 200 is connected to a commercial power source of 60Hz. Insertion of a lamp device into a wrong lighting fixture is thus prevented.
