Title: Communication station, method and system for controlling communication
IPC: H04L12/417
Filed: 1992-03-19
Abstract: PURPOSE:To obtain a communication system where abnormality in a transmission line is coped with in the transmission line multiplexing system of a token bus network. CONSTITUTION:Silence or a bad signal outputted from the reception data detecting part of CBM 6 is inputted to the diagnosis of a change-over control part 11, a transmission change-over signal 104 is outputted at the time of continuing beyond monitoring time and the selection of a reception transmission line by a multiplexer 8 is changed-over. A station which restarts communication by transmission line change-over keeps contact with another station as to the change-over transmission line by a data frame which is transmitted/received in a communication processor 4. Therefore, the transmission line is immediately changed-over at the time of transmission line abnormality so that the communication system with reliability and high efficiency is realized without a control station.

Abstract: PURPOSE:To form an excellent crystal such as a single crystal containing no grain boundary, a polycrystal being grain-boundary controlled, etc., without being constrained by a foundation material by crystal-growth treating a base body with a free surface on which a non-nucleating surface and a nucleating surface having an area sufficiently small for crystal growth only from a single nucleus are arranged adjacently. CONSTITUTION:Crystal formation treatment is executed to a base body having a free surface on which a non-nucleating surface (SNDS) having small nucleation density and a nucleating surface (SNDL) having an area sufficiently small for crystal growth only from a single nucleus and nucleation density (NDL) larger than the nucleation density (NDS) of the non-nucleating surfaces (SNDS) are disposed adjacently, and a single crystal is grown from the single nucleus. A thin-film 5 having small nucleation density is shaped onto a substrate 4, and a material of a different kind is deposited onto the thin-film 5 and patterned to finely form a nucleating surface 6. The single nucleus of a thin-film material is shaped onto the nucleating surface 6 by the proper conditions of deposition, the nucleus is grown, keeping single crystal structure and changed into an insular single crystal grain 7, and the grain 7 is further grown to coats the whole thin-film 5. A single crystal 7A if flattened through etching or polishing to form a single crystal layer 8.

Title: Vacuum pump
Inventor: IKEMURA KAZUHIKO
IPC: F04D19/04
Filed: 1988-03-18
Abstract: PURPOSE:To enable eliminating of material stuck and deposited without stopping operation by providing a plurality of discharge ports and a means for selectively opening/closing the respective ports, thereby closing the discharge port at which material reacted and generated is stuck and deposited while opening the other port. CONSTITUTION:When a motor 11 is driven, a pump mechanism member 6 is driven by a drive shaft 12, and gas sucked from a suction port 1 is compressed at the member 6, and thereafter it is pressure-fed to a discharge part 2'. In this case, a plurality of discharge ports 17a, 17b are arranged at the part 2'. When one of discharge ports 17a, 17b under open conditions is clogged by material stuck and deposited, the increase in the pressure inside caused by the clogging is detected by sensors 18a, 18b, and thereby a direction switching valve 19 is actuated. As result, one of the ports 17a, 17b is closed when it is clogged, while the other is opened. The port having trouble with the clogging is removed from the switch over valve 19 and the material stuck and deposited thereto is removed.

Title: Amplifying circuit
Inventor: YOKOYAMA KENJI
IPC: H03F3/00
Filed: 1980-05-15
Abstract: PURPOSE:To reduce the occurrence of noise, by connecting a negative impedance between the input terminals to which a signal source is connected. CONSTITUTION:For a negative impedance circuit 4, the nonreverse and reverse inputs of an operational amplifier 5 are connected to the output terminal (b) and the output terminal (b') via a resistance RX respectively. The output of the amplifier 5 is fed back to the nonreverse and reverse inputs via feedback resistances R3 and R4 having an equal resistance value. The circuit 4 functions as a whole as a negative impedance -RX. In this case, to increase the dynamic range, the value is advantageously reduced for both the resistances R3 and R4. In such constitution, only the signal source impedance RS is put into the signal route as a noise source. As a result, the S/N can be improved.
