Title: Synthesis of diamond by vapor process
Inventor: HIROSE YOICHI
IPC: C30B29/04
Filed: 1986-10-09
Abstract: PURPOSE:To produce a diamond particle having easily controllable particle diameter in high efficiency and reproducibility, by using a diamond-deposition substrate material subjected to sputtering treatment prior to the deposition of diamond by vapor-phase decomposition of an organic compound. CONSTITUTION:A surface of a diamond-deposition substrate made of Si, SiC, etc., is preliminarily subjected to sputtering treatment to roughen the substrate surface to a state uniformly roughened in submicron order. The sputtered substrate for the deposition of diamond is placed in an apparatus for the production of a diamond by vapor process and an organic compound such as methane, methanol, etc., is thermally decomposed in vapor phase to effect the growth of a diamond particle on the deposition substrate. A number of diamond particles can be independently grown on a substrate. A diamond film can be produced by continuing the growth of the diamond particles over a long period until the particles are connected with each other.

Inventor: KAWAGISHI KENJI
IPC: H02P27/06
Filed: 1990-09-10
Abstract: PURPOSE:To enhance performance of an air-conditioning unit without causing degradation of motor efficiency or increase of the capacity of inverter element by performing constant control of the instantaneous power factor of an induction motor based on a preset reference value so that maximum efficiency can be achieved without being subjected to pulsating instantaneous load torque. CONSTITUTION:In order to perform constant control of the instantaneous power factor at a high efficiency point without being subjected to pulsation of load, phase difference are taken out between phase voltages Vu, Vv, Vw outputted from an inverter 10d and motor currents Iu, Iv, Iw thus producing phase difference signals. Assuming the phase difference signals and an induction motor 1a have four poles, signals are produced twelve times per single revolution. The phase difference signals are fed to an instantaneous power factor detecting circuit 19 thus producing an instantaneous power factor signal cosphi. The instantaneous power factor signal is then compared, in a comparator 21, with a reference power factor command signal cosphi* fed from a reference frequency command-reference power factor command converting circuit 20, and an instantaneous power factor control circuit 22 performs learning control thus controlling the power factor constantly so that the induction motor 1a exhibits a maximum efficiency.

IPC: H01L21/302
Filed: 1992-09-08
Abstract: PURPOSE:To prevent a deterioration of an etching shape of a connection hole at over-etching (O/E) when an insulation film is etched in a reaction system generating a deposit to form the connection hole. CONSTITUTION:A SiO2 interlayer insulation film 2 on a lower layer wiring 1 is etched through openings 4, 5 of a resist mask 3 using c-C2F8/S2F2 mixed gas. This etching forms a deposit layer 6 composed of S separated and generated from S<2>F2, and in the inside of a shallow via hole 2a completed previously, the deposit layer 6 is easy to become excessive as compared with the inside of a deeper via hole 2b. In particular, when there is the thick deposit layer 6 on an opening end surface of the resist mask, the patterns are transferred to the side wall surface of the via hole 2a at O/E to generate a crease-form convex and concave. After the deposit layer 6 has once been removed by any method of wafer heating, O2 plasma processing, and an inclined ion emitting, O/E will be performed.

Filed: 1985-10-25
Abstract: PURPOSE:To stabilize the temp. of a metallic mold by supplying steam to a temp. control chamber in the mold to preheat the mold, then supplying cooling water to the temp. control chamber and heating or evaporating the cooling water via the heat input of a casting material. CONSTITUTION:The temp. control chamber 2 is formed to approximately comply with the surface shape of the cavity in the metallic mold 1.

Title: Sweep light frequency generator
Inventor: NOGIWA SEIJI
IPC: H04B10/00
Filed: 1997-09-04
Abstract: PROBLEM TO BE SOLVED: To provide a sweep light frequency generator in which its optical loop circuit is constituted of polarization dependent parts and is capable of outputting a light pulse signal train having stable light intensity while intersecting the linear polarization state of light pulses orthogonally at every circulation. SOLUTION: The polarization state of the light pulses circulating in the optical loop circuit 100 is that of linear polarization which intersects orthogonally at every circulation. Both of optical frequency shifters 5, 6 for shifting the optical frequencies have polarization dependent loss characteristics. The respective optical frequency shifters are connected to a polarization separating element 4 in compliance with the polarization plane of the input light pulses so as to minimize the input loss of the light pulse signal to be inputted. A polarization synthesizing element 8 multiplexes the outputs of the respective optical frequency shifters and returns the polarization state of the light pulses outputted therefrom to the same state as the state at the point of the time when the light pulses are inputted to the polarization separating element 4.  As a result, polarization mode dispersion is canceled at every circulation and the ripples in the output light pulse signal train are suppressed.

Abstract: PURPOSE:To define dynamic and multiplex hierarchical structure by assigning a logical line numbers meaning a logical coupling condition to one hierarchical structure. CONSTITUTION:A machine family is recognized as one hierarchical structure, logical line number codes (a coupling order code, a selection order code and a coupling state code) indicating the logical coupling order and state are set up to hierarchical relation at an optional level based on the product structure of a representative machine type and the structure of an object is uniformly regulated based on the set of the combinations. Namely, one hierarchical structure is selected as an object and relation between plural constitutional elements A, B having the hierarchical relation at an optional level is defined by using the logical line number to set up the reference unit of the structure. Consequently, technical data relating to the design and production of products can be uniformly controlled by using a generalized dynamic and multiplex hierarchical structure model capable of expressing the function constituting order and a multiplex and dynamic characteristics of the hierarchical structure.

Abstract: PURPOSE:To uniformly form a thin compound film of high quality by introducing microwaves simultaneously with the introduction of a reactive gas into a vacuum tank to produce high-density and high-energy electron and gas ions and then passing clusters through the above region. CONSTITUTION:A reactive gas is introduced into a vacuum tank 1, and simultaneously, microwaves of nearly several gigahertz are introduced.
