Title: Exhaust device for two-cycle engine
Inventor: KUSHIDA KAZUMITSU
IPC: F02B27/06
Filed: 1985-06-28
Abstract: PURPOSE:To push back a blowing mixture into a combustion chamber and obtain high filling efficiency by introducing fresh air into an exhaust passage near an exhaust port when a mixture blows from the exhaust port, and burning pre-combustion gases in exhaust gases. CONSTITUTION:Combustion gases exhausted from an exhaust port 10 with the operation of an engine 1 are discharged to the atmosphere through an exhaust passage 11, an expansion chamber 13 and a muffler 14. In this case, the number of revolutions of a crank shaft 2 is detected by a sensor 22 and the result of the detection is inputted in a control unit 24. And when the engine 1 has reached a high speed range, an actuating signal is outputted from said control unit 24 to an actuator 23, thereby opening a change-over valve 18. Then, a branch circuit 17 is released and a low pressure condition is formed within the exhaust passage 11 near the exhaust port 9, thereby opening a check valve 19. At this stage, fresh air from a cleaner 25 is sucked into the exhaust passage 11 and pre-combustion gases in exhaust gases are mixed with the fresh air for combustion.

Title: Hot-electron transistor
Inventor: YUASA YOSHIHIRO
IPC: H01L29/201
Filed: 1986-06-18
Abstract: PURPOSE:To improve a device in its performance characteristics by a method wherein a collector barrier is constituted of a superlatice for an improved transfer ratio or current amplification factor. CONSTITUTION:A collector barrier is built of a superlattice in this design. In an appropriately designed superlattice, an auxiliary conduction band is gener ated, wherein electrons may be in presence, under a normal conduction band. In a collector barrier 12, there exist auxiliary conduction bands 1 and 2. Upon application of bias voltages VBE and VCB, those equipped with energy higher than that of the collector barrier 12, out of electrons 3 that have tunneled through an emitter barrier 14, arrive at a collector 16 and, as for those equipped with energy lower than that of the collector barrier 12, they can also arrive at the collector 16 though only after passing through the auxiliary conduction band 1 or 2. In this way, probability is lowered of electrons' being stopped by the collector barrier 12, which results in an increased transfer ratio or current amplification factor.

Title: Sheet holder
Inventor: NOMOTO MINEO
IPC: H01L21/68
Filed: 1987-06-10
Abstract: PURPOSE:To hold a soft sheet member without local deformation by interposing a substance provided over the whole surface with a function of passing fluid such as air in the direction of thickness between said sheet member and the surface of a sheet holding portion to hold the sheet member with vacuum adsorption. CONSTITUTION:As a general substance provided with a function of allowing fluid to pass therethrough is there a filter allowing liquid and gas to pass through a film to separate the substance from the liquid and gas. This filter 2 is interposed between a sheet (green sheet) 1 and the surface of a sheet holder portion (chuck) 4 to adsorb and hold the sheet 1. Then, local attraction acting from an attracting hole 3 in the surface of an adsorbing holder portion 4 is dispersed over the whole filter 2. Thus, the average attraction acts from numerous fine holes formed in the filter 2 so that even soft sheet 1 can be adsorbed and held without being deformed. Also, if the filter 2 is polluted, the filter 2 is exchanged so that actual damages due to the pollution can be easily removed.

Title: Method for investigating changing state by measuring radius of curvature of lined tunnel surface
Inventor: KAKIUCHI YUKIO
IPC: G01C7/06
Filed: 1999-05-24
Abstract: PROBLEM TO BE SOLVED: To make graspable the degree of changing slate from the initial shape by calculating a shape such as an initial radius of curvature or the like of a lined concrete, and comparing the shape such as the radius of curvature or the like by each section measurement result with the initial shape. SOLUTION: The surface of a lined concrete when constructed has a constant radius of curvature. The surface of a lined concrete of an existing tunnel is measured and abnormal values are detected from many section measurement results with the use of a statistic method, whereby a degree of deformation is clearly grasped as indicated by a table and a graph, and correction points are determined. A tunnel-measuring machine which can measure a sectional shape of the liquid concrete of many points from one measurement point is used, so the sections at many points of the lined concrete are measured in a short time and many section measurement results are obtained. A shape such as an initial radius of curvature or the like is calculated from the results with the use of the statistic method.  Each sectional shape (series 1-7) and an initial shape (series 8) are compared at the spot by a computer to determine correction points.

Filed: 1993-06-15
Abstract: PURPOSE:To enhance the efficiency of line work while protecting the workers against exposure by making a decision whether an abnormality is present in an object under inspection and controlling the line work depending on the identified abnormal point. CONSTITUTION:An object 202 to be inspected is transferred on a work line 201 into an X-ray CT system 203 where the object 202 is inspected and a tomographic image thereof is displayed 204 while simultaneously recorded 205. The inspected object 202 waits at a waiting place 206. Inspection results are called from a recording medium 205 during movement of the object 202 in order to make a decision whether an abnormality is present. When no abnormality is present, a moving direction changing unit 208 shifts the object 202 from the place 206 to a predetermined work line. When an abnormality is present, an abnormal part identifying section 209 calls the inspection results from a medium 205 and identifies an abnormal part. Furthermore, a line work controller 208 controls the unit 208 to shift the object from the place 206.
