Title: Radio information transmitter and radio information transmitting method
Inventor: IZUMI SEIICHI
IPC: H04B15/00
Filed: 1999-06-15
Abstract: PROBLEM TO BE SOLVED: To reduce noise from a transmitter other than an opposite communication party by allocating M pieces of n rows M*n columns non square matrixes obtained by dividing M*n rows M*n columns square orthogonal matrix to each transmitter, multiplying each vector consisting of data of one block having n pieces of samples by it and performing random orthogonal transformation. SOLUTION: A random orthogonal transformation(ROT) circuit performs ROT processing of a ROT matrix 29 where the number of rows is more than the number of columns, into an input symbol vector 26 consisting n pieces of samples converted into symbols by a modulator. A 3n-fold symbol vector 30 is subjected to inverse fast Fourier transform(IFFT) processing and is transmitted and a receiving side performs fast Fourier transform(FFT) processing of the received data. A bit mapping circuit converts a symbol obtained by such a manner that an inverse random orthogonal transformation (inverse ROT) circuit performs inverse ROT processing of the data into data and then, they are decoded. Thus, it is possible to cancel an interference wave from a transmitter other than a true opposite communication party and to reduce noise.

For example, linearly polarized light 103 having passed through the first polarizing plate 3 is transformed to elliptically polarized light 101' when it passes through the liquid crystal cell 5. The elliptically polarized light 101' is transformed to elliptically polarized light 102' which is approximately equal to linearly polarizeed light by placing an optical delay plate 10 above the liquid crystal cell 5, allowing the light 102' to become sensible to human eyes through the second polarizing plate 4. Thus, a liquid crystal display device having noncolored light background and wide view field angle is obtd. inexpensively.

Abstract: PURPOSE: To prevent generation of a biting wear between a rotor and a side housing member by providing a rotor body of aluminum alloy and installing an iron spacer for maintaining a space with the side housing member on the both sides front and back in an axial line direction.  
     CONSTITUTION: A rotor body 6 is of aluminum alloy and a spacer 43 of iron for keeping a space with side housing members 2, 3 is installed on the both sides front and back in an axial line direction. Under this constitution, even if the rotor 6, for some reasons, were displaced in an axial line direction and a side seal 41 compressed a corrugated plate spring 42, being pushed inwardly on a side seal groove 40, the head 43 of the ferrous spacer 43 which tends to easily fit an aluminum alloy contacts the side housing members 2, 3, preventing further approach. As a result, a bite does not generate between the rotor 6 and the side housing members 2, 3, thus enabling use for a long time.

Title: Traveling stop controller for unmanned work vehicle
Inventor: YAMAMOTO SHIGEHIRO
IPC: A47L9/28
Filed: 1993-06-15
Abstract: PURPOSE:To reduce an area where the work is tried again, by keeping an unmanned work vehicle traveling up to a position where the body of the vehicle can touch an obstacle as close as possible based on the data on the area of the obstacle. CONSTITUTION:The data showing an area where the obstacles can touch the body 10 of the unmanned work vehicle are previously stored in the work traveling data 31. A controller 30 recognizes the present position of the body 10 based on the signals received from the encoders 17 and 18 and decides whether the body 10 is included in the preceding area or not based on the data 31. If a sensor 11 detects an obstacle when the body 10 is not included in the area, the controller 30 stops the body 10 with a room secured to the obstacle. Meanwhile, the controller 30 reduces the traveling speed of the body 10 when the sensor 11 detects an obstacle when the body 10 is included in the area. Then, the body 10 is made to stop after it moved by a distance that can be presumed between the body 10 and the obstacle when the traveling speed of the body 10 is reduced. As a result, the parts to be cleaned again, for example, can be decreased.

Abstract: PURPOSE:To prevent yielding of judder and insufficient clutching in such a way that strings which are high and low in their resin ratio separately installed to only the equivalent rate on the inner circumferential side are simultaneously taken up in the first instance, then only the string which is low in its resin ratio is taken up in order that a half-finished goods made of looped friction material can be manufactured. CONSTITUTION:First with the work of a side cylinder 4, a take-up head 5 is closed, then when a counter-cylinder 6 goes ahead, and take-up preparation is over, a chucking 7 is opened, and take-up is commenced. Simultaneously cylinders 8, 9 go ahead, and get into the condition as shown in the second figure. Upon giving the take-up completion signals on the inner circumferential side, only an impregnated string 11 which has high resin ratio is cut off, and only an impregnated string 10 which has low resin ratio is taken up. Furthermore, take-up is continued, and when signals for completion of take-up on the outer peripheral side are transmitted, also the string 10 is cut off, and take-up is completed. Thus, a friction material obtained by machining the half-finished goods made as such is favorable for both insufficient clutching and judder feature.
