Title: Proximity switch for detecting metal ball
Inventor: ISHIBASHI KEISUKE
IPC: A63F7/02
Filed: 1990-04-11
Abstract: PURPOSE:To provide the output representing the absence of a metal ball irrespective of the presence of the passage of the metal ball by using a substrate type PNP transistor so that the emitter is made 0V by the irradiation of strong electric waves. CONSTITUTION:A substrate type PNP transistor Tr 1 has a collector in common on to a substrate and earthed in the circuit to constitute an emitter follower circuit. When strong electric waves, for example 40W electric waves with 430MHz are irradiated near a coil in an oscillating circuit 2 with metal balls being intermittently passed by, the Tr 1 is turned off to give low voltage near 0V to the emitter. Since the potential of the emitter of the Tr 1 is lowered rapidly during the irradiation of the electric waves, a transistor Tr 2 and transistor Tr 3 are turned on to reduce the output thereof. thus, irrespective of the presence of passage of the ball, the output judging the absence of the metal ball is generated.

The metal such as Al, W, Mo and the like or the silicide which is the compound of Si and a metal is formed thereon as a wiring material 13. Besides, an SiO2 layer 14 is formed thereon. Then, a patterning is performed on the wiring material 13 and the SiO2 layer 14, and the Si3N4 layer 12 is exposed on the part other than the wiring pattern. Subsequently, a polycrystalline Si layer 15 is selectively deposited on the Si3N4 layer 12 only under the condition of selective deposition method. As a result, the polycrystalline Si layer 15 begins to grow from the surface of the Si3N4 layer 12, and the layer 15 does not grow in the least from the SiO2 layer 14. The polycrystalline Si layer 15 is deposited up to the upper part of the SiO2 layer 14 by adjusting the period of deposition as above-mentioned, and the surface can be flattened easily. As a result, the deposition surface can be made flat by selectively depositing the deposition material utilizing the difference of the density of nuclei formation of the deposition material.

Abstract: PURPOSE:To prevent occurrence of a short-circuiting accident and interference between the power sources of the same kind of devices even when the devices are to be connected with a common talking channel, by providing a means which detects the presence/absence of a voltage across the talking channel, control means, etc. CONSTITUTION:When a user depresses an operation button 7 for talking, a control means 5 detects the voltage across talking channels 3 and 4 through a voltage detecting means 6. If the channels 3 and 4 are not occupied by another device, no voltage exists across the channels 3 and 4 and the means 6 transmits information 'no voltage' to the control means 5. Upon receiving the information, the control means 5 turns on a switching means 2 and power supply is made to the channels 3 and 4, and thus, talking with another device through a transmitting/receiving circuit 8, etc., becomes possible. Since a voltage exists across the channels 3 and 4 when they are occupied by another device, the voltage is detected by the voltage detecting means 6 and information 'voltage exists' is transmitted to the control means 5. Upon receiving the information, the control means 5 maintains the switching means 2 under a turned off-state. Therefore, a short-circuiting accident, etc., between power sources can be prevenetd even when the same kind of devices are connected with a common talking channel.
