Title: Photovolatically growing method
Inventor: YAMAGUCHI AKIO
IPC: H01L21/205
Filed: 1985-07-18
Abstract: PURPOSE:To enable selectively the production of a fine structure by disposing a substrate in a vacuum chamber, and selectively producing a substance to be produced from a raw gas by the heat of the substrate and the emission of an optical interference pattern to the substrate on the substrate. CONSTITUTION:A substrate 11 is disposed in a vacuum chamber 12, and regulated at the prescribed position. Then, the chamber 12 is exhausted, the substrate 11 is heated to remove surface absorption gas, and the entire surface is cleaned by sputtering with Ar ion gas. Then, raw gas 13 is fed to the chamber 12, and the substrate 11 is emitted by an entire surface emitting system. An InP buffer layer 11a produced from the gas 13 without surface contamination is formed on the entire substrate 11 by this operation. Then, the layer 11a is emitted by an interference pattern system. In this case, the pitch of an interference moire 14 is set to the prescribed value. This operation is repeated to form by epitaxially growing the desired corrugated lattice 5a made of InP on the layer 11a. The thus formed lattice 5a has a lattice pitch of the interference moire 14 and a sectional shape of sinusoidal wave shape.

Inventor: KENT ROSSMANN
IPC: C23C16/50
Filed: 1998-06-08
Abstract: PROBLEM TO BE SOLVED: To control introduction of contaminant produced in a deposition chamber composition member into a CVD processing chamber by seasoning the processing chamber with a protective film having a low contaminant diffusion rate before a substrate is introduced into the processing chamber. SOLUTION: An etchant gas, e.g. NF3 , is introduced into a processing chamber 10 and a protective seasoning layer is deposited upon finishing a standard processing chamber cleaning work for removing a material deposited on the chamber wall from from the preceding deposition step. Silicon nitride is deposited as the protective seasoning layer using a computer program stored in the memory 33 of a CVD system 5. More specifically, a source generator 32 is set with a set value by pressurizing the chamber 10 at a set level and a bias generator 36 is set with a set value. Subsequently, a process gas containing nitrogen and silane is introduced into the chamber thus depositing a protective seasoning layer of silicon nitride having a low contaminant diffusion rate.

Title: Anti-skid braking device
Inventor: TANAKA RYUICHI
IPC: B60T8/48
Filed: 1994-06-17
Abstract: PURPOSE:To positively prevent a water hammer phenomenon at the time of anti-skid control on the road surface with a friction coefficient in any grade by disposing a pressure reducing valve for reducing fluid pressure fed to an anti-skid control valve device from a master cylinder during anti-skid control. CONSTITUTION:The pressure of a wheel cylinder 10 rises stepwise. When the flow velocity of an operating fluid passing through a changeover valve 7 is fast at the time of changeover from brake fluid pressure rise to constant holding in this stepped charging, a water hammer phenomenon is generated in a conventional anti-skid braking device, but since the stepped piston of a pressure reducing valve 5 is in a movable state, the pressure reducing control of the operating fluid flowing toward the changeover valve 7 at the time of brake fluid pressure rise is performed to reduce the flow velocity of the operating fluid passing through the changeover valve 7. The water hammer phenomenon is not therefore generated even in the case of the changeover valve 7 being placed in the cut-off state from the communicating state every step in this stepped charging.

Filed: 1986-07-09
Abstract: PURPOSE:To miniaturize and lighten an optical system by using a Savart plate for an analyzer for magneto-optical reproduction. CONSTITUTION:A light beam emitted from a semiconductor laser 1 transmits through a collimator lens 2, a polarizer 3, and a beam splitter 4 sequentially, and is condensed on the surface of a magneto-optical recording medium 6 by an objective lens 5a set in an actuator 5. A part of the light beam thus condensed on the surface is reflected by the medium. The reflecting light beam is divided by the beam splitter 4, and the plane of polarization is rotated by pi/4 by a 1/2 wavelength plate 11 equipped with a rotating mechanism 13. Thus rotated reflective light beam is polarized and divided in parallel with its optical axis by the Savart plate 12, and conducted to a halved photodetector 18 by a condenser lens 9. Information signals which are the output from the both photodetectors 18a and 18b of the halved photodetector 18 are conducted to a differential amplifier 19 from which a differential signal is outputted.

Then, the region BCD of the low average degree of Pu enrichment is disposed to face the control rods 500 to obtain high reactivity with the water of a wide water gap. The high reactivity is obtd. by increasing the average degree of Pu enrichment in the region ABD which faces the narrow water gap and where moderators are apt to be deficient.

Filed: 1997-06-17
Abstract: PROBLEM TO BE SOLVED: To reduce the distortion of a probe microscopic image and to obtain a vivid image by adjusting the approach angle of a probe and a sample surface so that the ratio of physical quantity and a moving distance changed by a distance between the probe and the sample surface may be maximum and performing measurement after confirming the normal direction of the sample surface. SOLUTION: Piezoelectric elements 4 and 5 for correcting an angle are attached to the lower part of the sample board 3 of the scanning probe microscope. The probe is made to come close to the sample surface so as to become in an observation feasible state. The probe is fixed on a plane and feedback control is interrupted. The probe is moved by a fixed distance in a z-axis direction so as to acquire the physical quantity. The element 5 is moved in an x-axis direction so as to incline the sample board 3, and the measurement is repeated. After fixing the sample board 3 at a position where the physical quantity is maximum, fine adjustment is similarly performed by the element 4 in a y-axis direction. Since the decided position of the sample board 3 is nearly perpendicular to the probe, the elements 4 and 5 are fixed in the midst of the measurement.

Abstract: PURPOSE: To perform a uniform adsorption of carbon dioxide gas from an entire surface of an inner box and improve a thermal insulating performance by a method wherein a thermal insulating box is formed of an inner box having a plurality of layers composed of an inner layer made of plastic material and an outer layer made of non-adhesive plastic material containing adsorbing powder for use in adsorbing carbon dioxide gas. CONSTITUTION: An inner box 6 is comprised of an inner layer 7 made of polypropylene and an outer layer and a non-adhesive outer layer 9 containing adsorbing powder 8 for adsorbing carbon dioxide gas and having foaming thermal insulating material. Foaming thermal insulating material 4 is filled between the inner box 6 and an outer box 3 to form a thermal insulating box 1. With such an arrangement, the adsorbing material powder 8 contained in the outer layer 9 causes carbon dioxide gas in the air bubbles of the foaming thermal insulating material 4 to pass through the non- adhesive surface of the outer layer 9 and then carbon dioxide gas is uniformly adsorbed from the cells in the foamed thermal insulating material 4.  With such an arrangement as above, since the carbon dioxide gas can be uniformly adsorbed from the entire surface of the inner box 6, it is possible to improve a thermally insulating performance of the thermal insulation box 1.
