Abstract: PURPOSE:To make it possible to implant an ion beam to a wafer of more than 6 inches in a constant direction constantly by applying the same voltage to the electrodes of a first and a second multi-pole electrostatic deflector and rastering a sample surface with parallel charged ion beams in a constant direction constantly. CONSTITUTION:The same voltage is applied to the electrodes of a first and a second multi-pole electrostatic deflector 2, 3. An ion beam is first deflected for a predetermined degree of angle at the first multi-pole electrostatic deflector 2 to fly through a drift space to get into the second multi-pole electrostatic deflector 3. The ion beam which has got into the deflector 3 is deflected for the predetermined degree of angle in the opposite direction to the deflected direction in the deflector 2, where its advance direction is changed to be parallel to its axis, and it goes out of the deflector 3 to be applied to a sample, so parallel sweep is achieved. For the first and second multi- pole electrostatic deflector, octpole electrostatic deflectors shall be used. Adjacent to the entrance of the second multi-pole electrostatic deflector, an aperture part 5 is provided for cutting a charged ion beam which has an orbit not to reach the sample directly.

Title: Measuring instrument
Inventor: TAGUCHI SHUNICHI
IPC: G01C19/04
Filed: 1985-07-10
Abstract: PURPOSE:To measure a position and azimuth with good accuracy by loading a rate gyro and rotary encoder on board the travelling robot travelling autonomously inside a plane face and by removing the effect of a disturbance. CONSTITUTION:The rotary encoder 8, 19 directly fitted to a wheel shaft measures the rotary pulse of wheels 7, 18 and the output pulse thereof is counted by pulse counter circuit 9, 20. The position of a robot is found from the extent of movement variation of the right and left wheels 7, 18 with said counted number and the wheel diameter. A rate gyro 10 outputs the angular speed of the robot, LPF11 removes the vibration of the gyro 10 itself and the vibrations from driving motors 5, 16 and passes through nearly the direct current component only. The azimuth of the robot is found with the time integration of the angular speed signal of the gyro 10 thereof. The gyro 10 is provided inside a thermostatic chamber since it is easily effected by the atmosphere. The self position and azimuth of a self travelling robot can thus be measured with good accuracy.

Title: Mobile communication base station device
Inventor: YOSHIDA KATSUYA
IPC: H04B7/26
Filed: 1993-06-22
Abstract: PURPOSE:To detect the deterioration of communication quality due to the leakage power, etc., of the adjacent channel of the frequency adjacent to the reception desired frequency by taking the ratio of the received electric field level information of at least two reception parts and comparing the value with a constant threshold value. CONSTITUTION:A discrimination part 5 lets two waves in the frequency relation adjacent each other which can be known from frequency designation information 4, for example, the adjacent wave for the reception desired wave of the frequency f0 be f'0 and f''0 among inputted N pieces of reception electric field level information 1C-NC. Where, f''0=f0$DELTAf;f''=f0+DELTAf:DELTAf is defined as a carrier interval. The ratio of the reception desired wave to the reception electric field level at respective reception electric field levels of the frequencies f'0 and f''0 are compared with a set constant threshold value. When the ratio exceeds the threshold value, the communication deterioration of the channel f0 due to the leakage power of the adjacent channels f'0 of f''0 is judged to be generated and to output the result.

Title: Liquid crystal display device and its driving method
Inventor: KATO TAKEHISA
IPC: G09G3/36
Filed: 1996-06-12
Abstract: PROBLEM TO BE SOLVED: To provide a liquid crystal display device which can reduce crosstalk by installing a control circuit for turning on all analog switches. SOLUTION: In the horizontal blanking periods, the OR gate control signal becomes the high level, thus the OR gate 12 outputs a high level signal to turn on all analog switches 11 although all the output lines 9 of the horizontal scanning circuit 8 become the low level. While in general video signals of maximum amplitude are inputted during horizontal blanking period, black signals are written into all signal lines 6 because liquid crystal display devices of normally white type accept black signals. When leak current is generated in a pixel transistor 1, black signals are uniformly mixed in the pixels in the longitudinal direction connected to the signal lines 6 since the signal lines transmit information of black signals. Thus, crosstalk in which image information is mutually mixed in the longitudinal direction hardly occurs.

Abstract: PURPOSE:To reduce oscillation threshold current and obtain large output, in a surface emitting type semiconductor laser device wherein polarization control is performed by using polarization beam split function. CONSTITUTION:A reflecting mirror 13 serving as an electrode is installed, which reflects a loss laser light L2 casted toward the outside of a resonator constituted of reflecting mirrors 2, 10 and returns the light L2 to an active layer 4 as a feedback laser light L3. The active layer 4 is excited also by the feedback laser light L3, so that the oscillation threshold current is lowered, and the heat generation in the active layer 4 is restrained. Hence a high output laser light L1 which is polarized in specified direction by a loss adding layer 20 can be led out to the outside.

Title: Semiconductor light emitting element

IPC: H01S5/00
Filed: 1991-06-24
Abstract: PURPOSE:To provide a semiconductor light emitting element from which a high optical output can be obtained with a small operating current and which emits super-luminescent light. CONSTITUTION:An active layer 2 and light guide layer 3 are removed from the rear side of this semiconductor element and only the active layer 2 is removed from the front side and the parts from which the layers 2 and 3 are removed are filled with a semiconductor layer 8 having a wider forbidden band width than the layers 2 and 3 have. In addition, both end sections of the element are constituted so that the sections can become no-current injecting sections even in a stripe area. As a result, high-output super-luminescent light can be obtained, because laser oscillation is suppressed by effectively remarkably suppressing the reflectivity on the rear side and output beam from the light guide layer 3 on the front side and the output beam can be taken out without loss from the layer 3 on the front side. In addition, the occurrence of optical damage caused by light absorption is suppressed.
