Title: Antenna system
Inventor: ASAI TAKAYUKI
IPC: H01Q3/18
Filed: 1987-10-31
Abstract: PURPOSE:To arbitrarily set a directional pattern after manufacturing, for example, after mounting work is completed at a site by providing a reverse conical reflector. CONSTITUTION:The reverse conical reflector 3 is supported within the radiant range of a radio wave due to a unidirectional antenna 1 by a strut 4. And in case of installing the unidirectional antenna 1 just underneath the reverse conical reflector 3, the radio wave 6 reflected on the reflector 3 is radiated uniformly in an omnidirection, and an almost circular radiating plane 5 centering the antenna system is formed. Next, in case of installing the unidirectional antenna 1, for example, by shifting leftward, the radiation of the wave is deviated to a left side. In other words, by changing the relative position of the unidirectional antenna 1 and the reflector 3 by an antenna frame 2, it is possible to obtain a desired wave radiant pattern.

Abstract: PURPOSE:To reduce heaping of reaction products which suppress etching reaction and to enlarge an etching grade, by adding a small amount of carbon compound containing oxygen and either fluorine or hydrogen as reactive gases when a contact hole and a throughhole are formed by a reactive ion etching method. CONSTITUTION:When a contact hole and a throughhole are formed by a reactive ion etching method, a small amount of carbon compound containing oxygen and at least either fluorine or hydrogen is added in a flow rate ratio of 20-40%. In this method, because of little heaping of reaction products suppressing an etching reaction, an etching grade to be obtained becomes large, and besides because of few reaction product heaped on a silicon substrate 3 serving as a base film and on a first metallic wiring layer 1, a contact resistance and a throughhole resistance become stable and small, so that the contact hole 4 and the throughhole 7 can be formed with high quality by this etching method.

Abstract: PROBLEM TO BE SOLVED: To control acceleration voltage properly stably against wobbling and noise at the time of layer jump by eliminating high-frequency components such as noise of a driving signal and detecting zero-crossing point of a focussing error signal with histeresis. SOLUTION: A driving signal for a pickup 3 from a focus control circuit 8 is inputted in LPF 14 through a changeover switch 19b. Then, high frequency components such as noise are eliminated but low frequency such as wobbling are not, with the signal supplied to an adder 17. In the movement to other focussing point on a recording surface, a micro computer 13 switches the changeover switch 19a, 19b to the jump side, setting the rising/falling voltage of a specific value in a circuit 15, 16 for setting such voltage value. After that, it is switched to the rising voltage side and supplied to the pickup 3. Then, a focus zero crossing detector 12 detects the zero crossing point of a focussing error signal with histeresis, switching it to the falling voltage side by the micro computer 13. Consequently, the focusing point is surely moved.
