Title: Semiconductor device
Inventor: SUGIYAMA NAOHARU
IPC: H01L21/20
Filed: 1998-02-13
Abstract: PROBLEM TO BE SOLVED: To reduce the thickness of a crystal layer as a substratum for obtaining a strained silicon layer, by forming semiconductor crystal which has a lattice constant different from that of an insulating crystal thin film and a thickness free from lattice relaxation, on the insulating crystal thin film formed on a crystal substrate. SOLUTION: A CaF2 layer 12 as an insulating crystal thin film is formed on a silicon substrate 11 as a crystal substrate which has (100) azimuth on a crystal surface. An side layer 13 as a first crystal thin film is grown on the CaF2 layer 12, and grown up to, e.g. 100 nm in film thickness. At this time, the SiGe layer 13 is excellently lattice-matched with the CaF2 layer, and strain in the SiGe layer 13 hardly exsists after growth of 100 nm. An Si layer 14 is grown up to, e.g. 15 nm in film thickness continuously with the growth of the SiGe layer 13. The Si layer 14 is maintained in the state that tensile strain is applied. Thus the Si layer 14 to which tensile strain is applied can be formed on the thin SiGe layer 13.

Title: Method for discriminating faulty section of repeating transmission line
Inventor: OGURA HARUO
IPC: H04B17/40
Filed: 1984-02-21
Abstract: PURPOSE:To discriminate a faulty section momently and easily by detecting a difference of arrival time between feeding currents, which are propagated from a faulty point in both directions, in a loop-shaped feeding circuit to detect the faulty point. CONSTITUTION:When taking notice of currents I1 and I2 flowed to feeding device output terminals L1 and L2 of the loop-shaped feeding circuit, I1=I2 is true as long as the loop is closed. If a trouble such as a cable disconnection or the like occurs at a certain point of the loop and feeding is broken, step currents which have the same magnitude and have polarities opposite to each other are generated at the faulty point, and these step currents are propagated in both directions and reach feeding-side terminals L1 and L2 with a difference of arrival time corresponding to the difference between transmission lengths from the faulty point. Consequently, this difference of time is measured to discriminate the faulty section.

Title: Semiconductor light-receiving element
Inventor: TAKAHASHI KAZUHISA
IPC: H01L31/10
Filed: 1988-02-12
Abstract: PURPOSE:To obtain high absorption efficiency and to make it possible to operate at a low operating voltage by diffracting incident light by diffraction grating in the direction intersecting a depletion area and by making the width of the depletion area wide. CONSTITUTION:A diffraction grating 20 disposed together in the photodiode 10 that operates by absorbing light in a depletion area generated by applying a reverse bias to a p-n junction is formed in the same substrate. The light incident from a grating part 20 is diffracted to the depletion area formed in a p-type Si layer 2 of the diode part 10 by a grating part 20. Since light traverses the depletion area, high quantum efficiency is obtained by widening the depletion area. This makes it possible to operate the element at a low voltage.

Filed: 1997-02-17
Abstract: PROBLEM TO BE SOLVED: To eliminate noise by arranging a porous material in the air flow and generating a sound of reverse phase for a noise generated from an apparatus thereby canceling the noise. SOLUTION: In a body frame 105, contaminated air is purified through a dust collecting section 100 and a fan 200 to produce clean air. In the dust collecting section 100, dust being charged by a corona discharge beam 101 is captured by a dust collection plate 102. When the air is passed through the dust collecting section 1O0 by means of the fan 200 comprising a rotary machine 201 and a rotary blade 202, noise is generated and picked up through a microphone 1. A phase modulator 2 modulates the phase of a sound wave detected by the microphone 1 at an appropriate timing and the modulated sound wave is delivered from a speaker 4 through a voice generator 3. Sounds from the air and the speaker pass through the porous material 10 arranged in the air path along with noise.  They are combined effectively through sound wave interference and the sound level of combined sound wave approaches zero.

Title: Gas flux control method by electromagnetic valve
Inventor: TAMURA AKIRA
IPC: F23N5/14
Filed: 1981-03-05
Abstract: PURPOSE:To correctly control the opening of a valve corresponding to a temperature change by vibrating a plunger for driving a valve and by always reversing the direction of magnetization in a magnetic circuit to eliminate magnetic hysteresis. CONSTITUTION:While a pulse current flows through one coil L1, electricity flows through the other coil L2 to be turned off. When pulse A1 flows through the coil L1, and pulse A2 flows through the coil L2, they are turned on electricity in such a manner that the direction of each magnetic flux is opposed to each other. While the coil L1 or L2 is excited by a pulse current, a magnetic circuit is formed by a yoke 12 and a plunger 11, and the plunger 11 is attracted to the lower end of the yoke to lessen a gap G, so that the reversal of magnetization can eliminate magnetic hysteresis, whereby the opening of a valve can be correctly controlled corresponding to a temperature change.
