Title: Pinhole and interferometer with pinhole
Inventor: MURAKAMI KATSUHIKO
IPC: G01B9/02
Filed: 1998-09-22
Abstract: PROBLEM TO BE SOLVED: To provide a pinhole which achieves a higher durability by enabling to make a light transmission hole with the diameter dimension of 1 μm or less easily and at a lower cost. SOLUTION: A microscopic light transmission area 31 transmitting incident light and a scattering area 32 scattering light by increasing the roughness of the surface of a substrate 30 are formed on the surface of the substrate 30 adapted to transmit light with a specified wavelength. The microscopic light transmission area 31 is formed by smoothing the surface of the substrate 30 locally into a circle with a specified dimension and the scattering area 32 has an irregular fine ruggedness formed on an area except for the microscopic light transmission area 31 on the surface of the substrate 30. Out of the light incident on a pinhole, that incident on the scattering area 32 is scattered and the incident beam on the smoothed microscopic light transmission area 31 is emitted passing through the substrate 30.  In the use as pinhole of an interferometer, it can be so arranged to emit a spherical wave from the microscopic light transmission area 31.

Title: Interferometer
Inventor: BRUCE JACOBSEN
IPC: G01B9/02
Filed: 1998-09-22
Abstract: PROBLEM TO BE SOLVED: To measure wavefront aberrations with high accuracy even when a light source having a short coherence length is used by obtaining interference fringes by causing a first luminous flux diffracted through a pinhole and a second luminous flux to interfere with each other while the arrangement of one of first to third optical means is corrected by using the information on an angular change obtained by means of a fourth optical means. SOLUTION: Parallel rays of light transmitted through a second objective lens 9 are divided into a plurality of diffracted light beams by providing a diffraction grating 10 between the lens 9 and a mask 11. The mask 11 has a small pinhole and a large window and the 0-order diffracted light beam is condensed to the pinhole. The first-order diffracted light beam is condensed to the center of the window and the other diffracted light beams are cut by means of the mask 11. The light beam diffracted through the pinhole becomes a spherical wave and used for a reference wavefront. The light beam transmitted through the window is used for a test wavefront. The reference wavefront and test wavefront are superimposed upon an image pickup element 13 through a leans 12 and form interference fringes. The lens 2 works to form the image of the pupil surface of a test optical system 6 on the detecting surface of the element 13. The wavefront aberration of the test wavefront is found by analyzing pictures by means of a computer 19.

Title: Heat exchanger for vehicle
Inventor: NAKAMURA HIROTAKA
IPC: F01P3/18
Filed: 1997-10-01
Abstract: PROBLEM TO BE SOLVED: To restrict deterioration of performance of a cooling medium condensor in a heat exchanger for a vehicle in which an auxiliary cooling radiator for a heat generating device is mounted on the cooling air upstream side of the cooling medium condensor. SOLUTION: For a cooling medium condenser 2, a position so an auxiliary radiator 3 is set in such a way that a part of a cooling medium exit side zone without overlapping with the auxiliary radiator 3 is formed. In the cooling medium exit side zone in which cooling medium temperature becomes the lowest in the cooling medium condensor 2, therefore, cooling air of low temperature without passing the auxiliary radiator 3 (without heat-absorbed by the auxiliary radiator 3) can be fed to flow. Temperature difference between cooling medium and cooling air can thus be sufficiently secured in the cooling medium exit side zone of the cooling medium condensor 2 even when outer air is at high temperature, and thereby deterioration of performance of the cooling medium condensor 2 can be restricted.

Then, the prescribed recording, reproducing or erasing operation, etc., is executed. After the operation is finished, the slider main body 13 is moved to the recording film not-forming area A and the rotation of the magneto-optical disk is stopped. Thus, the floating type magnetic head can be prevented from getting contact with the information recording area B of the information recording medium.

Title: Semiconductor device and manufacture thereof
Inventor: HIRABAYASHI TAKAYUKI
IPC: H01L21/60
Filed: 1998-09-24
Abstract: PROBLEM TO BE SOLVED: To form a bump very close to a semiconductor element with reduction effect on shocks and the like applied on the semiconductor element in a chip, even after the completion of the semiconductor chip. SOLUTION: A thick shock-absorbing layer 21a is formed only at the lower side of a source electrode 18 of a MESFET. When a bump 20 is formed after the completion of a semiconductor chip, pressure and shocks applied on the source electrode 18 as the pad are absorbed and alleviated by the shock- absorbing layer 21a. Thus, the breakdown of a semiconductor substrate 10 and the MOSFET can be prevented. Furthermore, since the shock-absorbing layer is not formed at a region which is other than the lower side of the source electrode 18, parasitic inductance component can be suppressed, and high-speed operation of the MESFET will not be obstructed.
