Title: Transistor
Inventor: HIKINO TETSUYA
IPC: H01L29/72
Filed: 1977-12-07
Abstract: PURPOSE: To expand the effective operation region of a striped transistor with an uniform current flowed to its circumferential region, by forming an epitaxial layer grown on a semiconductor substrate thicker than usual and by making only the lower circumferential region, touching the substrate, high in impurity density through ion injection.  
     CONSTITUTION: On N + -type substrate 22, N-type layer 21 which becomes a collector region is epitaxy-grown, in which the P-type base region is diffusion-formed, and a plural number of N-type emitter regions are provided there, so that the striped transistor will be constituted. At this time, epitaxial layer 21 is grown to a thickness thicker than the fixed one by about 0.1μm, and photo-resist film 25 provided onto layer 21 is used as a mask for injecting P +  ions so as to convert the lower circumference of layer 21 touching substrate 22 into N + -type layer 26 before each region is provided to the surface part of layer 21. Consequently, a current will not converge on the center region but flow uniformly to even the circumference, so that its effective operation region expands, the gain and output will increase.

Title: Liquid metal ion source
Inventor: FUTAMOTO MASAAKI
IPC: H01J27/26
Filed: 1982-08-27
Abstract: PURPOSE:To ionize a substance having relatively high vapor pressure at a melting point and improve life and reliability of an ion source by keeping higher introducing gas pressure in an ionization chamber for accommodating needle- shaped chip than that of a vacuum exhausting line by exhausting from a small hole connecting to a high vacuum line. CONSTITUTION:A gas having desired pressure can be introduced in an ionization chamber 6 through a needle valve. The gas in the ionization chamber 6 can be differentially exhausted through a small hole 7. By this differential exhausting, gas pressure in the ionization chamber 6 is kept higher compared with high vacuum side. By increasing gas pressure in the ionization chamber to a pressure range which occurs no glow discharge when liquid metal ion source is operated, vaporization of ionized liquid metal is suppressed and a stable ion radiation is achieved for a long time.

Inventor: UCHIYAMA KAZUHIKO
IPC: H04B1/10
Filed: 1999-05-27
Abstract: PROBLEM TO BE SOLVED: To suppress noise in an orthogonal frequency division multiplex(OFDM) modulation signal. SOLUTION: An intermediate frequency signal SIF is demodulated and a noise component in a null part (non-signal part) is detected as a noise component included in a signal with a subcarrier frequency. A frequency f0 of a reference frequency signal LO is feedback-controlled in response to an error rate detected by an error correction section 23. Thus, a subcvarrier in the intermediate frequency signal SIF frequency-converted by a mixer 16 on the basis of the reference frequency signal that is feedback-controlled is parted from the noise component on a frequency axis. A digital mixer/FFT arithmetic section 21 applies Fourier transform to the intermediate frequency signal SIF to suppress the noise component.
