Title: Method and device for evaluating silicon wafer
Inventor: OGITA YOICHIRO
IPC: G01N27/00
Filed: 1992-09-11
Abstract: PURPOSE:To measure and evaluate the crystal characteristics of a crystal layer in the surface of a wafer, including a zero defect layer, non-destructively and in a non- contact state by a method wherein impulse light and an electromagnetic wave are simultaneously applied to the surface of the wafer and the characteristics of the surface layer of the wafer are analyzed on the basis of the photo-conductive attenuation waveform of the electromagnetic wave reflected. CONSTITUTION:In a wafer 1 which is used as an object of evaluation, a crystal layer region 3 on the side of the water surface 2, in which defects in a surface layer are not formed, is formed. Any treatment is not performed on the wafer rear 5, crystal defects are concentrated in the interior of the wafer and an internal defect layer 4 is formed. Excitation light 6 is applied at a wavelength selected from among wavelengths of 180 to 890nm in an impulse manner in such a way that the infiltration length of the light 6 exists in the region (DZ) 3. Then, a probe wave 7 is emitted on the same position, a point P, as the irradiation position of the light 6 on the wafer surface 2 using the millimetric wave of a frequency of 30 to 3000GHz. Thereby, if a reflected wave 8 of the wave 7 is detected, a change in the photoconductive attenuation of the wave 8 can be known and evaluation of the interior of the wafer can be made.

IPC: G02B7/28
Filed: 1997-09-08
Abstract: PROBLEM TO BE SOLVED: To accurately set a focal position without being influenced by the brightness of an object by performing automatic focusing of hill-climbing method when it is bright and automatic focusing of a whole scanning method when it is dark.

IPC: B62D113/00
Filed: 1983-12-23
Abstract: PURPOSE:To make a driver easily frontward ahead a corber, by making an all- wheel-steering gear so as to change a car body attitude in order to cause it turn to the inner side of a turning direction when the car accelerates at the latter half cornering. CONSTITUTION:A computer 12 receives a detection signal out of a detection sensor 13 for body's lateral motion such as a lateral acceleration sensor, a yaw rate sensor or the like, and feeds a control signal commensurate to this signal to a rear wheel steering survo actuator 8, performing the rear wheel turning steerage required.

Inside the computer 12, an operational process (e) takes place on the basis of the front data (d) whereby control information d4 is secured. And, it is subtracted from rear wheel turn-steerage information d2 by a subtraction process, and (+ or -d2-d4) is fed to the servo actuator 8 and thereby a car body attitude is made to be headed toward the inner side of a turning direction.

Title: Strut for drum brake
Inventor: SUZUKAWA SHOICHI
IPC: F16D65/09
Filed: 1994-10-07
Abstract: PURPOSE: To provide a strut which is devised to suppress a shoe gap from a decrease to an excessive low value. CONSTITUTION: A second engaging member 40 is formed of an aluminum alloy having the coefficient of linear expansion higher than that of the steel of which a rotary drum 2 is formed and the coefficient of linear expansion of the whole of a strut 34 is comparatively increased. Thereby, when a drum brake temperature is increased simultaneously with an excessive pressure force being generated at the rotary drum, a shoe gap is not increased so much based on a difference in the coefficient of linear expansion and an automatic adjustment amount is comparatively decreased. Thus, even when, during application of a drum brake, the inside diameter of the rotary drum is increased through press of a brake shoe, it is suppressed by a shoe gap automatic adjusting mechanism that a shoe gap is excessively decreased and in turn, the drag of a brake is suitably prevented from occurring.
