Title: Wireless lan system
Inventor: KOBAYASHI HISAFUMI
IPC: H04L12/28
Filed: 1995-01-11
Abstract: PURPOSE: To switch a master station in a short time without searching for the master station when a new master station needs to be connected as a result of roaming from cell to cell. CONSTITUTION: A mobile slave station 14 searches for a master station which can be connected periodically and the address of the found master station which can be connected is stored in a master station management table 25. If the mobile slave station 14 roames from one cell to another in this state, the state of a communication with the old master station 121 becomes worse. When the state of the communication with the old master station becomes worse and the new master station needs to be connected, the mobile slave station 14 sends a connection request to the master station held in the master station management table 25 to make a communication through the new master station 122 .

Title: Multi-layered-film reflecting mirror for soft x-ray
Inventor: ITO KAZUHIKO
IPC: C23C14/08
Filed: 1990-01-10
Abstract: PURPOSE:To improve durability by making thicknesses of a high refraction index layer and a low refraction index layer, equal thickness by which X-rays reflected by boundaries between each these layers intensify each other, and by making a high refraction index layer of a multi-layered-film reflecting mirror for soft X-ray, of a B2O3. CONSTITUTION:On a base plate 1, an Ni layer 2 and a B2O3 layer 3 of each around 99 layers, for instance, are laminated by sputtering to form a multi- layered film structure. The Ni layer 2 is a low refraction index layer and the B2O3 layer 3 is an high refraction index layer. By a slight difference between the refraction indices of the two layers 2 and 3, a very little amount of soft X-ray is reflected at the boundaries between the both layers 2 and 3. Thicknesses of the Ni layer 2 and the B2O3 layer 3 are set so that phases of the reflected soft X-rays may coincide and those reflected waves may intensify each other. With this procedure, much higher durability than a conventional Li-system/Ni multi-layered-film reflecting mirror, can be obtained.

Title: Dispersal signal eliminating circuit
Inventor: SUZUKI YOUSUKE
IPC: H04N7/20
Filed: 1990-01-10
Abstract: PURPOSE:To eliminate a dispersal signal of any level by sampling the level of a synchronizing signal portion of an input video signal, comparing the level with a preceding sampling level to detect the amplitude of the dispersal signal component, thereby varying the level of triangle wave fed to an input signal. CONSTITUTION:An signal inputted an input terminal 1 is led via a subtracter 2 to a synchronization recovery circuit 3, where synchronization recovery is implemented. The DC level of a horizontal synchronizing signal for a period at upper and lower polygonal points of a triangle wave in the output of the synchronization recovery circuit 3 is sampled by a sample and hold circuit 6. The sampled value is inputted to a level detection circuit 7, which detects the absolute value of the difference between levels increased/decreased in a field. The output of the level detection circuit 7 is inputted to a control terminal of a VCA 5 to adjust the output amplitude of the triangle wave generating circuit 4 to a level in response to the input dispersal signal component. The output of the VCA 5 is fed to the subtracter 2, which subtracts an output signal of the VCA 5 from the input signal. Thus, the dispersal component is eliminated.

Title: Thick film hybrid integrated circuit-board
Inventor: TANEI HEIKICHI
IPC: H05K3/46
Filed: 1983-01-14
Abstract: PURPOSE:To enable to obtain the circuit-board on which the precision of resistance values is excellent and the soldering property of a wiring conductor on a top layer is favorable by a method wherein crystallized glass not containing the lead element is used as material for an insulating layer between two layers of the top layer and a sublayer, both respectively consisting of a wiring conductor and a resistor. CONSTITUTION:A first layer wiring conductor 2 and a first layer resistor 3 are formed on a ceramic substrate 1, an insulating layer 4 is formed in such a way as to cover the first layer registor 3 and on the insulating layer 4 are formed a second layer wiring conductor 5 and a second layer resistor 6. In this case, crystallized glass having a crystallizing temperature of 550-650 deg.C and not containing the lead element is used as material for the layer 4. The crystallized glass, which is lower than 550 deg.C in the crystallizing temperature thereof, is compositionally difficult to make a layer suitable for the layer 4, while the reaction with the resistor 3 is easy to arise if the crystallizing temperature thereof is higher than 650 deg.C and the change of resistance values attendant upon calcinating is abruptly increased. Moreover, since the layer 4 does not contain the lead element, the crystallized glass never reacts with the conductor 5. Therefore, the soldering property of the conductor 5 is never deteriorated.
