Title: Method and system for data input
Inventor: COPPER ANDREW JAMES
IPC: G06F3/038
Filed: 1998-11-26
Abstract: PROBLEM TO BE SOLVED: To accurately grasp the generation time of each data at a certain transmission destination when a plurality of data are inputted to a data transmission destination. SOLUTION: Information items are generated at data transmission sources 25 to 28 and the respective generated information items are transmitted to a data transmission destination 21 in the form of data packets. Relative time stamp values are calculated according to the delay time between the generation and transmission of the information items and incorporated in the data packets. The data transmission destination 21 decodes the data packets to extract the time stamp values and calculates the delay time of the data packets from the extracted time stamp values.

IPC: H01P5/18
Filed: 1997-12-05
Abstract: PROBLEM TO BE SOLVED: To provide a directional coupler capable of reducing deviation from 90 degrees in phase difference of two output. SOLUTION: First and second microstrip lines 2 and 3 almost parallelly arranged and connected to each other are formed into an almost quadrilateral spiral shape while turning the first microstrip line 2 to be on an inner side and the interval of the first and second microstrip lines 2 and 3 arranged by the mutually same circulation number is made wider than the interval of the first and second microstrip lines 2 and 3 arranged by the mutually different circulation numbers.

Title: Facsimile equipment with automatic answering telephone function
Inventor: NISHINO HIROTO
IPC: H04N1/32
Filed: 1989-12-25
Abstract: PURPOSE:To easily grasp number of incoming calls and incoming state of each signal by discriminating whether an incoming signal is a facsimile signal or a voice signal, counting number of times of incoming signals and recording individually each count. CONSTITUTION:When a call signal reaches via a telephone line 1 and an incoming call detection circuit 2 detects an incoming call, a hook switch 6 is closed and an OGM signal is sent to the telephone line 1. When an ICM (incoming trunk message) signal is sent from a caller in response to the OGM signal, a business discrimination section 15 discriminates the incoming signal to be a voice signal and gives a signal representing the entry of the voice signal to a counter 16. Thus, the counter 16 counts one entry of the voice signal and stores the count number. When a CNG signal representing the facsimile signal is sent, the counter 16 counts one entry of the facsimile signal and stores the count.

Title: River purifying facility
Inventor: FUJIOKA AKIRA
IPC: C02F9/00
Filed: 1997-11-25
Abstract: PROBLEM TO BE SOLVED: To provide a river purifying facility which makes it difficult for a contact material to be clogged with sludge and facilitates a sludge removal treatment. SOLUTION: For a river water W flooded from a grit chamber 11 over the upper end part of a first partition wall 10b, organic and inorganic pollutants are consumed by the biochemical action of micro-organisms and various bacteria growing on the surfaces of a group of crashed concrete pieces 15 in the course where the river water is moved as a downward flow in a downward flow treatment chamber 12. In a course where the water flows under a second partition wall 10c and moved horizontally to an upward flow treatment chamber 13 adjacent to a downstream side, sludge A2 is settled to the bottom part of sludge accumulated spaces 12a and 12b. In the upward flow chamber 13, the water directed in upward flow is subject again to the biological action of micro- organisms and various types of bacteria in the course passing through clearances in a group of crashed concrete pieces 15.  Thus, the river water W is purified by passing through the downward flow treatment chamber 12 and upward flow treatment chamber 13 alternately, and then circulated to a low channel of a river.
