Title: Distance measuring method via electromagnetic wave
Inventor: IMADA HIROSHI
IPC: G01S13/34
Filed: 1978-10-27
Abstract: PURPOSE:To secure a high-accuracy measurement of the distance even in case the distance to be measured is just several meters by shifting the antenna receiving the reflection wave from the subject of distance measurement and thus reducing the fixed error and the folded error with application of the phase modulation to the reception wave. CONSTITUTION:Microwave 3 of wavelength lambda and received the frequency modulation of about 10GHz is transmitted to measurement subject 13, and then the reflection wave is received from subject 13 through reception antenna 11 which is shifting by lambda/4 or the section of an integer-fold of lambda/4. The reception wave is mixed and detected along with the transmission wave to obtain beat wave 17 of both waves. This beat wave contains the short-distance information and also receives the phase modulation due to the shift of the antenna. The wave number of the beat wave is counted through the detection method of the zero-cross point and other method to obtain the information showing the necessary distance after the averaging process. The phase modulation covering from the initial phase to kpi is applied to the beat wave by giving the displacement to the antenna by lambda/4 or an integer-fold of lambda/4. Thus the folded error can be reduced to obtain a high-accuracy data of the distance.

IPC: B23C5/20
Filed: 1986-06-09
Abstract: PURPOSE:To decrease a time for arrangements and tools on hand, by continuously forming an upper surface cutting edge, having an arc-shaped or linear ridge line, on a peripheral side cutting edge so that the tool may perform cutting with no necessity for taking trouble on edge length of a mill and a machine tool even if a cut surface forms a shape of deep groove and curved surface or center spread. CONSTITUTION:A plate-shaped tip 1, having a mounting hole 11, provides a rake face 10 in one side and a fixed surface 101 in the other, continuously forming a protrusive cutting edge 12 and a linear cutting edge 13, as viewed from the side, in upper and bottom side surfaces. The tip 1, forming its cutting edge ridge line 14 with a bottom surface cutting edge 15 in a linear shape, as viewed from the plane, while a peripheral side cutting edge 16 and an upper surface cutting edge 17 in an arc shape and smoothly connecting these three contact points, forms a clearance angle 18 of ph fixed angle. In this way, the tip, only requiring a small effective edge length and efficiently performing also undercutting, decreases a cutting load to eliminate insufficiency of rigidity in a shank, and a machine tool is prevented from a defect by reducing the required horsepower and preventing chattering.

Filed: 1993-06-03
Abstract: PURPOSE:To surely get the instruction of the switching of a busy channel to a mobile station by increasing the transmission power of a base station when a channel switching instruction signal to the radio channel of an adjacent base station is transmitted. CONSTITUTION:A mobile station 11 has a transmission/reception part 111 for communicating with each base station 21 to 24 and a reception electric field intensity measuring part 112 for measuring the reception electric field intensity of the radio waves originated by each base station 21 to 24. When the base station 21 receiving a channel switching instruction from a radio control station 31 transmits the channel switching instruction signal to the mobile station 11 under the control, a transmission power control part 212 temporarily increases the transmission power of a transmission/reception part 211 and transmits the channel switching instruction to the mobile station 11 by constant transmission power which is larger than the transmission power to be used for the normal communication with the mobile station 11. Therefore, the transmission power of the base station 21 is increased to the value corresponding to that the coverage area of the base station 21 is as if it were magnified. In accordance with this, the electric field intensity in the mobile station 11 is increased.
