Title: Drive system of liquid crystal display receiver
Inventor: MAEZAWA SHIYUUJI
IPC: H04N5/66
Filed: 1984-06-21
Abstract: PURPOSE:To set the required number of scanning electrodes by deciding a start time of selection period of each scanning electrode as a prescribed time from the vertical synchronizing period independently of a field state of a video signal, and making optional the correspondence between the video signal and the scanning electrodes. CONSTITUTION:An output signal OSC of a voltage controlled oscillator VCO is frequency-divided to 1/2 by a flip-flop 31 and then frequency-divided to 1/8, 1/8, 1/4 by four-stage, four-stage, and two-stage shift registers 32, 33, 34. A pulse signal HCP at a 1/8 time at the end of one period is generated by a gate 35 and the phase is compared with that of a horizontal synchronizing signal HSP. Further, a clock signal CLA of the register 34 is 4 periods in one horizontal scanning time, it is used as a clock input of a counter 36, its output YCL is used as a clock signal for a scanning electrode signal, a vertical synchronizing signal VSP is used as a reset signal so as to obtain the corresponding ratio of 2:3 between the number of scanning electrodes and the number of scanning lines. Thus, the selecting timing of the scanning electrodes is generated in an equal time interval.

Title: Production of aluminum cast slab by twin roll continuous casting
Inventor: UEJIMA YOSHIYUKI
IPC: B22D11/00
Filed: 1993-05-31
Abstract: PURPOSE:To prevent the production of ripple mark and scab flaw in the reproduction of an aluminum cast slab by holding molten metal surface in a molten metal pool and casting roll to noncontact condition and further, the lower end of a contact limiting plate and the surface of the casting roll to the noncontact condition and to a specific interval and casting. CONSTITUTION:The contact-limiting plates 9 are formed of a graphite base refractory. Since the refractory has heat insulation property, the poured molten aluminum 5 dos not start the solidification on the molten metal surface 7, but the solidification starts at the point 11 contacting with the casting rolls 1-1, 1-2 below the molten metal surface 7. Therefore, the oxide film on the molten metal surface 7 is not entrapped into the cast slab 6 and further, even if the molten metal surface is moved, as the starting point of the solidification is not shaken, the ripple mark on the surface of the cast slab 6 is reduced. Further, in the case of arranging the contact-limiting plates 9 in the molten metal while bringing into contact with the casting rolls, as the scab flaw is easily generated on the surface of the cast slab 6, the interval between the lower end 10 of the contact limiting plate 9 and the casting roll is kept to <=2mm.

IPC: H05K3/46
Filed: 1998-05-12
Abstract: PROBLEM TO BE SOLVED: To prevent a soldering land which a conductor film gives from being narrowed more than necessity on account of spreading at the time of formation of a coating film, when miniaturization is intended and the area of a conductor film is reduced, in a thick film multilayer ceramic board in which an electrically insulating coating layer composed of material of low solder wettability is formed so as to cover the peripheral part of the conductor film giving a land for soldering an electronic component to be mounted. SOLUTION: A conductor film 26 is constituted of a first conductor layer 27 and a second conductor layer 28 which is formed thick on the first conductor layer 27 with its peripheral part exposed. A coating film 29 is so formed that it covers the peripheral part of the first conductor layer 27 but does not cover the second conductor layer 28. A step difference caused by the thickness of the second conductor layer 28 prevents the material of the coating layer 29 from spreading onto the second conductor layer 28.
