Title: Method for obtaining transmission gain function and transmitting device
Inventor: VOYER NICOLAS
IPC: H01Q3/26
Filed: 2001-10-09
Abstract: PROBLEM TO BE SOLVED: To provide a method wherein a transmission weighting vector is decided, the ratio of a signal to a noise plus an interference is optimized on a downlink and only the transmission of information in a small amount is required on an uplink. SOLUTION: In the method, a transmission gain function is obtained by an antenna array. A communication terminal transmits an uplink transmission signals (Su) to the array on a transmission channel referred to as an uplink channel. A downlink channel is disturbed by an isotropic noise (N') referred to as a downlink interference (Id) and/or a directional noise. The transmission weighting vector (-bd) is decided by a matrix product on the basis of a noise power matrix (Dd) as a function of the power of the isotropic noise and/or the power of the directional noise, and on the basis of a vector (-Cd) which is referred to as a downlink channel vector and which expresses the angular sampling of the transfer function of the downlink channel in M directions k, k=0,...M-1 belonging to an angular range covered by the array.

Title: Reader for linear scale
Inventor: KAMIHIRA TAKAHISA
IPC: G01B21/00
Filed: 2001-10-10
Abstract: PROBLEM TO BE SOLVED: To monitor the carrying-up or the carrying-down of high-order data and the synchronization of low-order data so as to prevent the generation of a readout error in a length measuring apparatus in which the high-order data and the low-order data are composited so as to be output. SOLUTION: When quadrants of an A/D area indicating the area of the low-order data agree with quadrants of a high-order area indicating the area of the high-order data (R2 , R3 ), a high-order counted value used to output the high-order data is output as it is. When quadrants (0, 1, 2 and 3) of the A/D area does not agree with quadrants (0, 1, 2 and 3) of the high-order area due to the carrying-up timing error or the like of the high-order data (R1 , R4 ), +1 or -1 is added to the high-order counted value, and the continuity of a length measured value is obtained when a scale is moved.

Title: Linear compressor
Inventor: HASEGAWA HIROSHI
IPC: F04B35/04
Filed: 2001-10-19
Abstract: PROBLEM TO BE SOLVED: To solve problems of efficiency and reliability that sliding surfaces of a cylinder and a piston are strongly brought into contact with each other at the diagonal positions on the top dead center side and the bottom dead center side by the side force of a resonance spring, the contact bearing pressure of these parts becomes very high, causing increase of sliding loss by the friction force between the piston and the cylinder and abnormal wear of the sliding surfaces. SOLUTION: A space is provided around the cylinder, and the cylinder is flexible by the configuration of preventing any restriction of an outer side of the cylinder. Since the resonance spring is inclined along the inclination of the cylinder and the piston, the cylinder and the piston are brought into contact with each other in an extensive range of the sliding surfaces, and thus, the sliding bearing pressure is reduced thereby. Therefore, increase of the sliding losses and abnormal wear of the cylinder and the piston is prevented, and the efficiency and the reliability is improved.

IPC: H04L29/12
Filed: 2001-11-02
Abstract: PROBLEM TO BE SOLVED: To stop the automatic address allocation service of a certain automatic address allocation device itself when another automatic address allocation device is driven in a network. SOLUTION: A radio LAN access point 1 to be functioned as an automatic address allocation device (DHCP (dynamic host configuration protocol) server device) sends a DHCP discover message to the network, and when a DHCP offer message is returned as its reply and the transmitting source address of the DHCP offer message is not matched with its own IP address, determines the existence of another DHCP server 61 in the network and stops its own DHCP server service. Since competition with the other DHCP server 61 can be evaded and the confusion of the network can be prevented, the radio LAN access point 1 can be suitably used for a small-scale office or a home network managed especially by a general user having no IP knowledge.
