Title: Semiconductor laser, modulation system and optical communication system using the same
Inventor: HIROKI TAMAYO
IPC: H04B10/572
Filed: 1994-12-17
Abstract: PURPOSE: To effectively obtain TE and TM polarized wave oscillation ranges by providing a phase shifter in one region, and differentiating an α parameter to the TE and TM waves. CONSTITUTION: Since TE and TM polarized waves have different effective refractive indexes (n), Bragg's wavelengths λ are different, and the wavelength difference is about 4nm. The relationship between the injection carrier density N and a gain (g) is such that, when the wavelengths are different, the value of dg/dN is different and the parameters are different (α parameter :4π/λ.(dn/ dN)/(dg/dN)). The relationship between the threshold currents of the two electrodes of the TE polarized wave is asymmetrical with respect to a straight line of 11 =12 since a λ/4 phase shifter 21a is provided only at the region of one electrode. Since the TM wave is different at the dg/dN from the TE wave, the threshold currents of the two electrodes are different. As a result, the lower one of the threshold currents of the TE and TM waves is easily oscillated.  Since the two curves are crossed, oscillating regions of the TE and TM waves are generated, and both the regions can be effectively obtained.

Title: Semiconductor device
Inventor: SEEVINCK EVERT
IPC: H01L21/8247
Filed: 1992-12-15
Abstract: PURPOSE: To read a instantaneous storage state out faster by connecting a memory cell to a read means, included in the current path between the emitter and collector of a transistor(TR). CONSTITUTION: This read means is arranged in the current path between a 1st power line 100 and a 2nd power line 200, including the current path between an emitter 11 and a collector 12. This current path enables detection of the storage state of a cell at not only the base, but also the emitter 11 and the collector 12. Then very large read currents flow to the emitter 11 and the collector 12 due to the amplifying function of the TR T1. Therefore, the read speed of the TR has less delays generated due to a parasitic capacitance than a known memory cell.

Title: Acoustic signal detection method and apparatus
Inventor: DONARUDO SHIYUMADERU
IPC: G02B26/02
Filed: 1989-12-26
Abstract: PURPOSE: To reduce the cost by determining the size of opening for passing a viscous substance depending on the pressure difference of fluid between the space surrounded by a thin film embedded with an optical fiber and an end cap and the space on the outside of thin film. CONSTITUTION: A thin film 7 is formed around a tubular framework 6 and a single mode optical fiber 8 is wound spirally around the thin film 7 thus forming spaces 9, 16 between the thin film 7 and an end cap 17. When this hydrophone is immersed into a fluid, a part of the fluid flows through a hole 15 into the hydrophone to elongate a bladder 12. Consequently, static pressure in the spaces 9, 16 is equalized to the static pressure of fluid on the outside of hydrophone and the fluid stops to flow through the hole 15. The hole 15 and the equalization hole 10 are made small enough to slow down the equalization rate. Variation of acoustic signal measured by the hydrophone causes the thin film 7 to expand or contract radially and to elongate or shrink the fiber 8 longitudinally.

Title: Fuel injection valve of internal combustion engine
Inventor: KATO TAKEHIKO
IPC: F02M61/10
Filed: 1997-12-05
Abstract: PROBLEM TO BE SOLVED: To satisfactorily control the timing of a needle starting to rise and injection starting, or the injection rate rising time with regard to a fuel injection valve used for an internal combustion engine. SOLUTION: A delicate control of lifting becomes incapable because although cylinder internal pressure is actuating on a sack 16 when a valve is closed but, when a needle 10 rises by any amount, high pressure fuel in an oil bank 15 flows into the sack 16 and suddenly pushes up the needle 10 by the increase of up load. Accordingly, the bottom 66 of a rod 60 on the lower part of a sliding shaft 62 receiving fuel supply pressure on its upper surface is provided by opposing it to the top face 18 of the needle 10. Because the sliding shaft 62 is limited of its downward movement range by the engagement of a step 64 with a stopper surface 65, a gap equivalent from several percent to ten or more percent of the full lifting amount of the needle 10 is formed between the bottom 66 and the top face 18.  The needle 10 becomes controllable as the rising speed slows down because the downward load acting upon the sliding shaft 62 offsets the increased up load.
