Title: Manufacture of bipolar semiconductor device
Inventor: KASAHARA MASAKI
IPC: H01L21/331
Filed: 1999-06-30
Abstract: PROBLEM TO BE SOLVED: To reduce the number of process steps and thereby simplify the process. SOLUTION: Phosphorus glass (PSG film) 2 containing phosphorus (P) is formed on an Si semiconductor substrate 1, and the formation of an emitter by diffusion is finished for a transistor to be formed on a bipolar IC. Then, as shown in step (b), a polycrystalline silicon film 4 is formed directly on the emitter-diffused film 2. Thereafter, as shown in step (c), a resist mask 6 having openings only at contact forming portions for connection with Al interconnections is formed, after which P ions of an n-type impurity are implanted in step (d) to form highly doped n-type polycrystalline silicon regions 4a as shown in step (e). In the step (e), the film 4 is processed to leave only the regions 4a and a film 4 portion interposed between the regions 4a on the film 2.

Title: Method for determination of ore composition
Inventor: TATEYAMA HIROSHI
IPC: G01N23/207
Filed: 1987-07-25
Abstract: PURPOSE:To enable sufficiently accurate determination even if the grain sizes of samples are nonuniform or the samples in a planar form or acicular form are oriented by correcting the results of the determination by using standardized orientation distribution functions. CONSTITUTION:Quantitative analyses of unknown samples are previously carried out by using an X-ray diffraction device and the theoretical strengths of respective ores are calculated by using lattice constants and atomic coordinates in accordance with the results of the quantitative analysis. Calculation is so made by multiplying the calculated strength values by the normalized Lorentz function that the peak shape coincides with the actually measured value. The volume term DELTAV of the sample is determined by using a nonlinear method of least squares in such a manner that the difference between the actually measured profile and the calculated peak profile is minimized. The orientation effects existing in the respective ores are eliminated by executing the orientation correction of the DELTAV by using the orientation distribution function by multiplying the corrected DELTAV of the respective ores by density. The weight ratios of the contents of the respective ores are thereafter determined by multiplying the corrected DELTAV of the respective ores by density. The determination of the ore compsn. is thereby enabled.

Abstract: PURPOSE:To receive a desired circular polarized wave effectively without receiving an unnecessary elliptic polarized wave by using a feeding circuit consisting of two hybrids and phase shifters in combination and a finite-length reflector plate and a couple of half-wavelength dipole antenna elements for feeding. CONSTITUTION:A feeding antenna 1 has the infinite-length reflector plate 2 and half-wavelength dipole antennas 3, and the feeding circuit consists of a phase shifter 5, a hybrid 6 for giving each antenna element 3 excitation amplitude, a phase shifter 7, and a hybrid 8.

Abstract: PURPOSE:To enable a stepless 0-100% capacity adjustment in a simple manner by a method wherein the air having a high pressure exceeding the rated pressure of a pressure regulating valve is supplied into a pressure receiving chamber in a sucking throttle valve and an unloading piston is shifted continuously in normal operation. CONSTITUTION:A part of air entered a relief pipe 12 flows into the pressure receiving chamber 1g of the sucking throttle valve 1 through a relief orifice 13. As a result, the unloading piston 1d shifts to the left and an unloading valve 1b also shifts to the left to come into close contact with the surface of a valve seat so that the starting of an unloading operation is completed. Next, when the compressor is switched from Y-operation to DELTA operation, an automatic air release valve 10 is closed and the air within the pressure receiving chamber 1g of the sucking throttle valve 1 is discharged into the atmosphere through a pipe 11 and the relief pipe 12 so that the unloading valve 1b is opened and the compressor sucks air so as to start its loaded operation. Further, when the compressor is in an crdinianry operation condition, the unloading piston 1a is shifted continuously due to the action of a pressure regulating valve 3 to thereby enable the 0-100% capacity adjustment to be made possible in a simple manner.
