Title: Headlamp for vehicle
Inventor: YOHANESUUGERUHARUTO BERUTORING
IPC: F21V7/09
Filed: 1993-03-01
Abstract: PURPOSE: To provide a headlight reflector allowing road passage and both edges of a road to be confirmed with good visibility, in particular, even during the occurrence of fog. CONSTITUTION: A light emitter 14 is arranged so that the longitudinal axis of the light emitter extends parallel to the optical axis 12 of a reflector 10. In the reflector 10, an apex region 22 reflects the light emitted from the light emitter 14 as light rays 24 converging and extending in longitudinal horizontal planes and produces great images 28 of the light emitter in both side edge regions of a measuring screen arranged in front of the headlight. Reflector regions 32,38 outside the apex region reflects the light emitted from the light emitter 14 as light rays 34, 40 which gradually less converge in longitudinal horizontal planes with increasing distance from the optical axis and produce, on the measuring screen, smaller images 36 of the light emitter 14 which form a horizontal light band. All the images 28 of the light emitter 14 are arranged underneath a bright/dark limit 30.

Title: Epitaxial wafer evaluation apparatus
Inventor: HIBINO MASAHIRO
IPC: H01L21/66
Filed: 1991-03-06
Abstract: PURPOSE:To enable the measurement of the lifetime of minority carriers and the Hall effect by switching between a Hall-effect measurement function for an epitaxial wafer and a lifetime measurement function for minority carriers by means of a changeover switch 5. CONSTITUTION:There is provided a cooling section 30 which is common to a section 3 for measuring the Hall effect of an epitaxial wafer and a section 4 for measuring the lifetime of minority carriers. A desired measurement is effected by the switching of a changeover switch 5 between the sections at the time of measurement. Thus, such an arrangement leads to the evaluation apparatus being reduced in size and enhanced in operating efficiency.

IPC: G01L5/00
Filed: 1980-03-28
Abstract: PURPOSE:To measure the acoustic velocity with high precision, by giving a fixed acoustic wave energy to the iron core by a hammer and delaying the signal for beating of the hammer by a delay timer to give this signal to the recorder as the start signal and by recording it. CONSTITUTION:Sensors 7 and 8 are fitted in the position where the clamping load of laminated iron core 1 should be measured. Hammer 6 is arranged on one face of iron core 1 to beat iron core 1. Thus, a fixed acoustic wave energy is given to iron core 1 by hammer 6. This acoustic wave energy which is propagated through iron core 1 is detected by sensors 7 and 8 and is converted to electric signals, and they are given to recorder 10. Detection outputs of sensors 7 and 8 are recorded on recorder 19 in a form of the propagation waveform. Delay timer 9 is installed in accordance with the fitting position of sensors 7 and 8, and the signal for beating of hammer 6 is delayed by this timer 9 and is given to recorder 10 as the start signal to start recorder 10. Thus, the acoustic velocity value is measured with high precision, and the clamping load is obtained with high precision.

Title: X-ray source radiating specific wave length x-ray containing no continuous spectrum
Inventor: CHIYOUSO TETSUO
IPC: H05G1/00
Filed: 1988-02-23
Abstract: PURPOSE:To intend an improvement of measurement sensitivity and accuracy, by generating an X-ray of a specific wave length almost not having continuous X-rays and by diminishing a background of an X-ray electron spectrum to be generated. CONSTITUTION:A primary X-ray source 1 radiating a primary X-ray X1 excited by a electron beam E has its target made of a Cu, a Cr and so on. A secondary X-ray source 2 radiating a secondary X-ray X2 excited by the X-ray X1 is made of an Al, an Mg, a Cu and so on. The X-ray source 1 and 2 are closely placed so that the X-ray X1 may irradiate into the X-ray source 2 before the X-ray X1 diverts substantially. By this way that the X-ray X1 from the X-ray source 1 irradiate into the X-ray source 2, there is no limitation of directions of X-rays, differing from a spectroscopic method, therefore, the X-ray X1 from the X-ray source 1 can effectively irradiate into the X-ray source 2 and an X-ray that has energy to be able to excite the X-ray source 2 excites effectively the X-ray source 2 thus an X-ray having a specific wave length can be obtained with very high effectiveness compared to the spectroscopic method.

Filed: 1978-04-07
Abstract: PURPOSE: To greatly reduce the rolling load, and to greatly increase the draft percentage, by positively giving the load to the idle roll, and by carrying out the different-speed rolling.  
     CONSTITUTION: In ths idle rolling, if the load is positively given to the roll 1 on the idle side by the hydraulic motor 3, a torque generates in the roll 1 in the direction to stop the rotation, and the difference between the peripheral speeds of the idle roll 1  and the driving work roll 2 increases; as a result, the rolling load can be greatly  reduced as compared with the case of the usual idle rolling. When the above stated  hydraulic motor 3 gives the idle roll 1 the load so as to make larger the negative  torque, the different-speed rolling nearer to the RD rolling can be carried out, so  that the reduction of the rolling load can be contrived.
