Title: Trimming method for frequency of surface acoustic wave element
Inventor: YAMAZAKI DAISUKE
IPC: H03H3/10
Filed: 1989-11-30
Abstract: PURPOSE:To manufacture a high stable surface acoustic wave element for both a long period and a short period by obtaining a target resonance frequency by executing frequency trimming which allows for frequency variation quantity generated by heat treatment, and thereafter, executing the heat treatment to obtain a targeted resonance frequency. CONSTITUTION:An electrode of a surface acoustic wave element is manufactured by dry etching, a frequency at that time is denoted as f1, pre-baking is executed so that a frequency shift does not occur exceeding some frequency, and a frequency at that time is denoted as f2. Also, when a frequency after frequency trimming is denoted as f3, the frequency f3 is determined by allowing for average  f0 of a frequency varied by post-baking executed after the frequency trimming. That is, the frequency f3 after the frequency trimming process is f3=f0- f0. In this regard, f0 is shown by a target resonance frequency. In such a way, a high stable surface acoustic wave element having the target resonance frequency f0 can be manufactured.

Title: Distance measurement method in optical burst communication and distance measurement system
Inventor: SAEGUSA NAOTAKA
IPC: H04B10/27
Filed: 1997-10-28
Abstract: PROBLEM TO BE SOLVED: To improve the accuracy of a delay instruction value, not by processing a clock function and a distance measurement function separately, but by using a phase difference between a reference clock from the clock function and a clock actually sampled as a fraction part to improve the accuracy of distance measurement. SOLUTION: For distance measurement in an optical burst communication where communication is conducted through an optical fiber between a plurality of subscriber's equipment and station equipment via a photocoupler, the processing result of a clock extracting function of burst data 16 is processed as a correction signal for distance measurement. In this case, a distance measurement device 25 is employed, which uses a phase difference between a reference clock 27 and a clock actually sampled as a fraction part, wherein the fraction part is processed for a correction signal of distance measurement, and the fraction part is used for a delay instruction value 26 between the subscriber's equipment and the station system.

Title: Gas sensor
Inventor: YOSHII MITSUYOSHI
IPC: G01N27/12
Filed: 1997-10-27
Abstract: PROBLEM TO BE SOLVED: To provide the heat stability of a dielectric constant by constituting a responsive membrane of a conductive polymer into which an anion species with a mol.wt. of a specific value or more or a diameter of a specific angstrom or more is introduced as a dopant. SOLUTION: A responsive membrane is composed of a conductive polymer into which an anion species with a mol.wt. of 250 or more or a diameter of 7 angstrom or more is introduced as a dopant. For example, the responsive membrane is constituted of the conductive polymer synthesized by using a substance represented by the formula (wherein R<1> and R<2> are each hydrogen, an alkyl group, a substd. alkyl group or halogen; and X<+> is alkali metal ions or quaternary ammonium ions) as an electrolyte to subject the same to electrolytic polymn. When the anion species having a large mol.wt. and occupying a large space is introduced as the dopant, the dopant is held between main chains of the adjacent conductive polymer to be made hard to move and, therefore, the falling-off of the dopant by heating is not almost generated and a change of conductivity is low.  As a result, even if the responsive membrane is heated, for example to 100 deg.C or higher for the purpose of purification, stable detection sensitivity can be kept.

Abstract: PURPOSE:To properly measure main components of catecholamine, changing-over the sensitivity of a measuring process from high to low after norepinephrine and epinephrine are eluted in a separation process. CONSTITUTION:Shift phase 20 is, through a separation column 12, openings 32a and 32b of a turn-over cock 18, a reactive coil 14, openings 32e and 32f, and a fluorescence detector 16, made conductive and stable in system, and then a to-be-examined sample is injected from an autosampler 22. At this time, a DE reagent tank 26 supplies a coil 14 with reactive solution, so the sample is separated in a column 12, norepinephrine, epinephrine and dopamine eluted in this sequence. The norepinephrine and epinephrine are respectively made to be ethylene diamine derivative, for fluorescence detection in high sensitive measurement of the first mode. In about 10 minutes after sample injection, dopamine eluate from the column 12 is, through the openings 32a and 32f, directly introduced into the detector 16, for fluorescence detection in the second mode of low-sensitive measurement. Thus main contents of catechol amine are quantified under proper conditions.

Title: Method for hardening tool edge
Inventor: ARIMI YUKIO
IPC: C21D9/22
Filed: 1987-12-08
Abstract: PURPOSE:To uniformly harden the whole tool edge and to obtain a desired hardened layer by projecting a defocussed high-energy beam on the edge of a tool, and making the irradiation angle on the edge side more acute than on the counter edge side. CONSTITUTION:The edge 2 provided along one side of the tool 1 set to a fixing jig 6 is irradiated with the laser beam 4 from the laser beam generator 3 traveling in the direction as shown by the arrow A, and simultaneously scanned. In this case, the beam 4 is focused by a lens 5, the focus F is set on this side of the edge 2, and the beam is defocussed and projected. As a result, the edge 2 is heated, and a hardened layer is formed. In the handling of the edge 2 of the tool 1, the direction of the beam 4 is set so that the irradiation angle theta1 to the irradiation surface on the edge 2a side is made more acute than the irradiation angle theta2 on the counter edge 2b side. Consequently, the overheating of the edge 2a is prevented, hence the whole edge 2 is kept at the practically same hardening temp., and hardening is uniformly carried out.

Title: Film unit with lens
Inventor: ICHINO SHUICHI
IPC: G03B17/04
Filed: 1997-11-13
Abstract: PROBLEM TO BE SOLVED: To improve recycling property without lowering the strength of a label. SOLUTION: A film sheet 31 for producing a label is constituted by providing an adhesive layer 33 coated with an acrylic or rubber adhesive to the back surface side of a laminated film 32 where a PP film 35 and a PS film 36 are laminated. By setting the tensile strength of the film 32 to >=7×10<3> M/m, the damage of the label caused by drop impact is prevented. By setting bending moment to <=3×10<-4> M.m, the flexibility of the label is held to prevent the blistering or peeling at a part covering over the curved part of a unit main body.  When the total amount of PP resin is kept <=1.5% with reference to the total amount of PS resin, the physical properties of the recycled PS resin obtained by simultaneously melting the PP resin and the PS resin are preserved, therefore the label is melted altogether in a state where it is stuck to a front cover and a back cover, and a label peeling stage is eliminated from a recycling stage.

Title: Power take-off operation mechanism for specially equipped vehicle
Inventor: OKADA NOBORU
IPC: F16D28/00
Filed: 1989-11-30
Abstract: PURPOSE:To make the beginning of engagement smooth and quick by transmitting a pull-directional operation force of an electric motor via a force accumulation means of a variable length damping type to a shifter of a power take-off, and making a ring gear engage with a power transmission gear. CONSTITUTION:Power from an engine 3 is transmitted via a transmission 4 to a power take-off gear secured to an input shaft 2 of the power take-off 1. When an electric motor 9 is driven, its operation force in the pulling direction causes, via an operation rod 7 and a force accumulation means 10 of a variable length damping type, a shifter in engagement with only the power take-off gear to shift. When the shifter begins to engage with a ring gear, the force accumulation means 10 accumulates force while absorbing its deformation by the reactional force of the ring gear. When the accumulated force reaches its limit, the shifter engages with the ring gear, the power transmission gear begins to corotate, the accumulated force is released, and the shifter is made to engage with the power transmission gear. Thus noise is prevented from being produced and gear teeth surfaces are prevented from being damaged.
