Patent JP-H04364035-A (JP)
Title: Electrode wiring
Inventor: SHIRAISHI YASUSHI
IPC: H01L21/3205
Filed: 1991-06-11
Abstract: PURPOSE:To increase a reliability of an electrode wiring by forming the electrode wiring with an Ag layer and metal formed on the Ag layer. CONSTITUTION:A Ti layer 2, a Pt layer 3 and an Au layer 5 are formed on a GaAs substrate 1 in this order. Due to the long-time use of the semiconductor device, Au atoms in the Au layer 5 diffuse into an Ag layer 4, forming an alloy layer 6 with Ag atoms. This alloy layer 6 is thermally stabilized and Au atoms hardly diffuse into the Pt layer 3 formed under the Ag layer 5. In other words, a further diffusion of Au atoms is prevented due to the stable alloy layer 6 formed between the Au layer 5 and the Ag layer 4. Also, Au atoms are prevented from being diffused through the end of an electrode wiring. Since the diffusion speed of Au atoms into the Ag layer is lower than the diffusion speed of Au atoms into diffusionproof layer such as the Pt layer, the Ag layer itself serves as a diffusionproof layer. Consequently, a leak current from the electrode wiring into the GaAs substrate does not increase and thereby a contact resistance does not increase at the wiring part on the ahmic electrode.

Title: Receiver authentication method
Inventor: INOTA MASAKI
IPC: G06F21/31
Filed: 1999-05-19
Abstract: PROBLEM TO BE SOLVED: To securely authenticate a receiver even when transmission information of a server increases by equipping the server with index information which indicates the storage position of receiver authentication data specifying a receiver for even plural pieces of transmission information. SOLUTION: A receiver authenticating process part 4 specifies the information management layer corresponding to requested information. The authentication information index of the specified information management hierarchy is obtained to retrieve the transmission information authentication control block corresponding to the request information according to the authentication information index, and it is decided whether or not the transmission information authentication control block corresponding to the request information is present according to the retrieval result. When the block is absent, the request information is transmission information requiring no receiver authentication, so an information providing process part 15 is requested to provide the request information.  Index information indicating the storage position of receiver authentication data specifying a receiver of transmission on information is included, so the authentication is enabled only by adding the index information.

The screen is divided into four quadrants and an area Si(i=1-4) of portions S1-S4 which are surrounded by large and small circles which are skins is obtained as the number of picture elements for each quadrant. The maximum and minimum of the area Si of each quadrant are obtained and they are set to Smax and Smin, respectively. PSmax/Smin is calculated from the Smax and Smin and this P becomes a parameter for center deviation. An allowable value is set for this P and it is judged whether the center deviation of an object to be inspected is proper or not.

IPC: H03L7/18
Filed: 1979-10-29
Abstract: PURPOSE:To enable the phase drawing-in over wide ranges, by controlling the up or down count of reversible counter with the phase comparison output between an input signal and a frequency dividing output signal to change the frequency dividing ratio of a variable frequency dividing circuit. CONSTITUTION:Carriers are fed to a terminal 1 before the transmission of video signal. A phase comparison circuit 3 is operative with a control signal CS1. A voltage controlled crystal oscillator 9 is oscillated at the center frequency, and the output frequency-divided at a variable frequency dividing circuit 5 is fed to phase comparison circuits 3, 6 as the reference phase signal. A reversible counter 4 counts a high speed clock Cl2 and sets the maximum or minimum frequency dividing ratio to a variable frequency dividing circuit with one comparative operation through up-count or down-count according to the comparison output of the phase comparison circuit 3. An average frequency detecting circuit 7 detects the average frequency of an input signal and presets it to a reversible counter. Thus, a broad range drawing-in is made possible even with an oscillator narrow in the variable range.
