Title: Surface acoustic wave device
Inventor: TAKAGI MICHIAKI
IPC: H03H9/25
Filed: 1993-12-24
Abstract: PURPOSE:To reduce the number of IDT electric conductors by providing an interdigital electrode IDT for exciting leaking elastic waves whose propagation direction is parallel to a +X axis and reflectors on both sides of it on a crystal wafer obtained by performing rotation in the direction of the +X axis in a specific angle range. CONSTITUTION:At the time of cutting the crystal wafer from single crystal, it is obtained by rotating a side +Y' 106 for forming the wafer for the angle of THETA=16-18.5 degrees from the direction of a mechanical axis 102 in the direction of an electric axis +X. A leaking surface acoustic wave propagation direction (l) is defined within 410 degrees to the +X axis of the crystal and the crystal wafer 700 is defined. Two one-port SAW resonators are parallelly arranged to it and a horizontal elastic coupling dual mode filter is defined. Then, a first one-port SAW resonator is constituted of the reflectors 704 and 706 and the IDT 705 and a second one-port SAW resonator is constituted of the reflectors 707 and 709 and the IDT 708. Further, by combining the rotation angle theta and the ratio of a leaking surface acoustic wave wavelength against an electrode thin film thickness so as to turn the first-order temperature coefficient of the resonance frequency of the SAW resonator to zero, the number of the IDT electrode conductors and the reflectors can be reduced.

Title: Capillary electrophoresis mass spectrometer and analyzing method
Inventor: TAYA TOSHIMICHI
IPC: H01J49/26
Filed: 1990-11-28
Abstract: PURPOSE:To improve an S/N ratio and analyze a mass accurately by detecting the moving speed of a separated sample by an ultraviolet ray absorber, control ling the voltage applied to the opposed ends of a capillary tube according to the detection signal, and thereby controlling the moving speed of the sample. CONSTITUTION:At the time point when ultraviolet rays are detected by ultraviolet ray detector 11 installed in front of an ion source 6 according to separation components which pass therethrough, a high voltage control circuit 12 is actuated to lower the output voltage V of a high voltage source 1. The electophoresis speed of a sample is thereby lowered to extend the measurement time for the alanalysis of mass. In this case, a mass analyzer 8 is set preliminarily to meet the ion mass number of sample components to be noted. While the background spectra of electolyte other than the sample components is zero (0) in the signal of the detector 11, from the time point when the sample components to be noted are separated and the signal starts to rise, the control circuit 12 is operated to decrease an application voltage V to thereby obtain the spectra of mass.

Title: Separator plate formed by layering fluorine resin
Inventor: ROBAATO PII ROSHIYU
IPC: H01M8/02
Filed: 1993-12-24
Abstract: PURPOSE:To provide a separator plate by which a barrier is formed to the electrolyte movement between double cells and the movement between the cells can be restrained by carrying a fluorine resin layer between a porous structure body and a graphite plate. CONSTITUTION:A separator plate is composed of at least a single porous structure body and a graphite plate, and not only at least a single fluorine resin layer exists as a barrier to the electrolyte movement between both of them but also electrical continuity exists between the porous structure body and the graphite plate. As for a unit cell having in it the porous structure body, though electrical continuity with the adjacent unit cell can be secured through the graphite plate, electrolyte is separated since the graphite plate and the fluorine type resin layer become a barrier. In this way, the electrolyte movement between cells can be prevented while satisfying requirements as a laminated body of a fuel cell.

IPC: C04B24/38
Filed: 1989-12-18
Abstract: PURPOSE:To enable to lower the pressure and temperature of a cement composition on the curing thereof to prevent the deterioration of organic fibers by employing silica sand and fry ash in a specific ratio as a silicic raw material in a composition containing the silicic raw material, organic reinforcing fiber, etc. CONSTITUTION:In a cement composition used for extrusion moldings and compounded with a cement, a silicic raw material, organic reinforcing fibers, a lubricant, a filler and methylcellulose (extrusion molding auxiliary), a 85:15-30:70 mixture of silica sand and fly ash is employed as the silicic raw material. The mixture is mixed with the other raw materials, further mixed with water, kneaded, extrusion-molded and subsequently aged in an autoclave at a stream pressure of 2-6kg/cm<2>. Since the particle of the fly ash is generally very small, the fly ash is highly reactive. The pressure and temperature of the composition can be thereby lowered to ranges, respectively, not affecting the organic fibers having low heat resistance. When the compounding ratio of the fly ash with the silica sand is larger than the range, the strength of the product is lowered, and when smaller, the rapid effect to the reaction is lost.
