Title: Network address management system
Inventor: YAMASATO TAKUMI
IPC: G06F13/00
Filed: 1992-06-05
Abstract: PURPOSE:To avoid mismatching of an address between host computers on a network by generating a packet for informing a change of a self-network address to the other host computer. CONSTITUTION:When a change request of a hardware address is generated, the own address changing part 1 executes a change of the own hardware address, and thereafter, generates a packet for informing the change of the own address to the other computer. Subsequently, the generated address change informing packet is transmitted onto a network 9. On the other hand, a host computer 10 which receives the address change informing packet analyzes it and fetches a changed protocol address of the host computer, and a changed hardware address. In this case, by using the protocol address as a key, an address storage table 4 is retrieved, and its hardware address is updated to an informed hardware address by the address change informing packet.

Title: Electromagnetic shielding method having frequency selectivity
Inventor: KAWASAKI KIMIO
IPC: H05K9/00
Filed: 1997-06-03
Abstract: PROBLEM TO BE SOLVED: To avoid impairing natural lighting and visibility, even for an electromagnetic shield on a glass, etc., by regularly arranging linear antenna elements in space, taking into account their equivalent electromagnetic reflection area to reflect radio waves and absorb part thereof. SOLUTION: Linear antenna elements 3 of lengths corresponding to the frequencies of radio waves to be shielded are regularly arranged on a nonconductive material such as window glass or in a space, while taking into account their equivalent electromagnetic reflection area to reflect the radio waves and absorb part thereof, thus ensuring a shielding of approximately 40dB at the max. A reflective zone around the antenna elements 3 ensures a shield performance, even if certain amount of gaps exists. This allows the antenna elements to be thinner wires and avoids impairing the natural lighting and visibility.

Title: Cmos selector circuit
Inventor: MIZUKAMI MASAO
IPC: H03K17/693
Filed: 1983-08-12
Abstract: PURPOSE:To attain the transmission with a sufficient signal level and also to decrease the number of components by inputting a signal through a transmission gate comprising plural MOSFETs to an input circuit having a positive feedback circuit. CONSTITUTION:P channel MOSFETs Q1-Q4 constitute respectively transmission gates transmitting input signals A-D and selection signals S0'-S3' are applied to each gate. Each said FET is turned on alternatively by each said selection signal and one of the input signals A-D is transmitted to a node N. The signal of the node N is fed to a latch circuit 1 comprising a CMOS inverter IV1 for output for compensating level and an N-channel MOSFETQ5 for feedback. The circuit 1 outputs an inverted signal according to the signal level of the node N. Since the level loss of the signal of the gate is compensated by a positive feedback circuit in this way, the signal with a sufficient level is transmitted even when the circuit is constituted by P or N channel MOSFETs only.

Abstract: PURPOSE:To detect a trouble damage caused by the entry of air into an exhaust system by making a decision of the trouble of the exhaust system if the mixture at the lower side of a three-way catalyst does not change to be enriched when the air-to-fuel ratio feedback control constant is kept limited to the enrichness compensating upper limit during the specified period or more. CONSTITUTION:Air-to-fuel ratio detecting means M3 and M4 are placed at the upper and the lower side of a three-way catalyst M2 and based on the output from the lower-side air-to-fuel ratio detection means M4, a computing means M5 computes the air-to-fuel ratio feedback control constant within the enrichness compensation upper limit. Using this control constant, a control means M6 computes the air-to-fuel ratio control variable on the basis of the output of the upper-side air-to-fuel ratio detecting means M3 to control an air-to-fuel ratio regulating means M7. In this case when a decision means 8 decides that the control constant is kept limited to the enrichness compensation upper limit during the specified period or more, and a decision means 9 decides that the lowser-side air-to-fuel ratio will not be changed to be enriched within the specified period, a trouble detecting means M10 detects that a trouble occurs at an exhaust system.
