Title: Abnormality detection system for automatic equalizer
Inventor: KAKO TAKASHI
IPC: H04B3/10
Filed: 1985-05-28
Abstract: PURPOSE:To detect earlier an abnormality of an equalizer by providing a symetricity decision section deciding the symmetry of the 2nd tape coefficient of an equalizing section of the post stage in an automatic equalizer where a couple of equalizing sections are connected i series and the equalizing section of the post stage is used as a symmetric equalizing section. CONSTITUTION:An adder 270 subtracts the real part of the 2nd tap coefficient and an adder 271 adds the imaginary part in the symmetricity decision section 27. Multipliers 272, 273 square the outputs of the said adders, apply absolute operation and an adder 274 adds the outputs of the said multipliers. A decider 275 compares an output of the adder 274 with a decision level H and when the output of addition exceeds the decision level H, a decision output representing a symmetricity of the tap coefficient is raised. The decision level H is set to a level seeming to be symmetrical substantially. Thus, if the symmetricity is lost completely, the output of addition exceeds the level H and it is decided as a symmetricity.

Title: Pulse generating circuit
Inventor: BILDGEN MARCO
IPC: H02P27/08
Filed: 1997-03-28
Abstract: PROBLEM TO BE SOLVED: To form a pulse which has been subjected to pulse duration modula tion, using a single-integrated circuit by transmitting an address signal with a prescribed timing, based on a signal which has reversely-processed the address of a word read-out from a memory. SOLUTION: This pulse generating circuit is constituted so that a word read-out from a memory 25 may be outputted into a registor 37 which is an address reverser. The resistor 37 read-outs the address in a direction opposite to the one written, and read-outs an electrical condition signal of high level on a read-out bus 39. The resistor 37 is connected with a comparator 41, and the comparator 41 transmits a control signal by comparing a binary comparison value predetermined for a binary value expressed with a transmitted address signal to make the control signal act on a multiplexer 51. The multiplexer 51 loads a resistor 45 with a numeric value according to a control signal value. It is thus possible to obtain the waveform of a pulse duration modulation signal with a memory word address in the memory 25, distributed in a harmonic way and kept in its permissible allowance.

Filed: 1990-05-02
Abstract: PURPOSE:To safely measure the distribution in a depth direction with a high resolving power by oxidizing the region corresponding to one atom layer of a solid surface, then heating the surface and simultaneously irradiating the surface with synchrotron radiation light to remove an oxide layer. CONSTITUTION:After the surface of a sample 2 is heated by a sample heater 3, introduced 4 oxygen is stimulated 5 and is directly blown to oxidize the surface.

Filed: 1997-05-06
Abstract: PROBLEM TO BE SOLVED: To provide good appearance and prevent a recessed portion from being accumulated with dust by covering recessed portions formed between neighboring vertical frames with an intermediate member as boundary. SOLUTION: Openings 11, 11 are formed at both the right and left sides with a column 10 as an intermediate member at the boundary. An attaching piece 14 of a vertical frame 13 constituting a sash window frame 12 is fixed on the exterior surface of a room with a fixing device 16, and a portion close to the outdoor of the vertical frame 13 is projected out from the outdoor surface of the column 10 to the outdoor side. Also, a recessed portion 17 opened to the outdoor side is formed on the outdoor surfaces of the column 10 and adjacent vertical frames 13, 13 with the column 10 as boundary. A strap 20 is attached striding outdoor members of the adjacent vertical frames 13, 13 with the column 10 as boundary. This strap 20 together with an intermediate strap 21, one side strap 22 and another side strap 23, is coupled with machine screws through a rear plate 24.  One side strap 22 and another side strap 23 are respectively fixed to the vertical frame 13 with machine screws 26, 27. In this way, the recessed portion 17 is closed with the strap 20. Thus, no dust is accumulated in the recessed portion. And when seen from outside, the adjacent vertical frames can be seen continuously with the intermediate member as boundary and this gives a quite neat appearance.
