Title: Characteristic display device for semiconductor sample by photoluminescence
Inventor: JIYAN RU BURI
IPC: H01L21/66
Filed: 1989-07-07
Abstract: PURPOSE: To display the characteristic of a sample with high resolution by providing a vacuum chamber, a mirror, and a laser beam. CONSTITUTION: An optical system 103 which transmits a photoluminescence beam 41 is displaced as against a sample 201, and the sample 201 and a vacuum chamber 1 are fixed. By these displacements, the optical system 103 observes the sample 201 appropriately up to an extent that each surface observed is excited by a laser beam 40 in an arbitrary region of the surface. For this, the beam 40 is transmitted to the sample 201 after double reflections by mirrors 20, 21. The mirror 21 is connected to the motion X of a platform 73 by a fixing means 81, and by connecting the mirror 20 to the motion Y of a platform 72 by a fixing means 80. Consequently, the mirrors 20, 21 are arranged so that luminous spots produced by the beam 40 on the surface of the sample 201 may be displaced in the same sirection precisely, and may be proportional to the object of the optical system 103.

Title: Method and device for correcting frequency for multiplex carrier signal
Inventor: KLANK OTTO
IPC: H04L27/26
Filed: 1997-06-30
Abstract: PROBLEM TO BE SOLVED: To provide the method and device by which a frequency deviation and jitter of a multiplex carrier signal are eliminated. SOLUTION: Both methods for automatic frequency control and common phase error evaluation are coupled in a feedback loop. The automatic frequency control is used to correct a frequency deviation in the case of initializing, the common phase error evaluation is used to correct remaining deviation and jitter after initializing. Thus, the frequency deviation and most of low frequency components of jitter of a local oscillator are eliminated without causing a marked phase noise.

Abstract: PURPOSE:To extract a high-purity negative phosphorus ion beam. CONSTITUTION:Solid phosphorus is gasified by a phosphorus oven 13, and phosphorus grains are guided into a vacuum chamber 1 and stuck to the surface of a sputter target 6'. The cesium from a cesium reservoir 9 is stuck to the same surface, and the target 6' is sputtered with the positive ions in the plasma by the rare gas such as argon or xenon fed from a guide port 2 to generate negative phosphorus ions.

IPC: B60G17/015
Filed: 1991-06-20
Abstract: PURPOSE:To prevent generation of an oil impact in value opening for solenoid proportional control valve for pressure fluid in a suspension controlling device. CONSTITUTION:A spool 33 is engaged with a valve main body 32 to slide freely, and a solenoid actuator 34 is connected with the spool 33.
