Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To contrive improvement of yield by bringing a metal coated probe into contact with metal material, and removing the coated metal of the edge of the probe by voltage application. SOLUTION: An elastic cantilever 102 which is metal-coated and whose edge has a sharp probe part 101 is made, a probe part 108 covered with metal is brought into contact with a metal substrate 105, electrode wiring 104 is conducted with a voltage application means 106, and voltage is impressed between the probe part 108 and the metal substrate 105. Thereby the coated metal film of the edge part of the probe is removed by electric field evaporation or heat fusion, and a minute opening 107 is formed. The diameter of the minute opening 107 can be controlled by controlling the diameter of the edge of the probe, film thickness of coating metal 103, contact force of the edge of the probe for the metal substrate 105 and a voltage application condition. It is in the range of about 10-100nm that the opening 107 can be stably formed.

Title: Combustion for pulverized coal and pulverized coal burner
Inventor: TANAKA TOSHIYUKI
IPC: F23C5/28
Filed: 1994-05-18
Abstract: PURPOSE:To easily control the decrease in NOx using a hydrodynamical mixture due to the interaction of three eddies. CONSTITUTION:Three burners of the same size are arranged at the top of an equilateral triangle on a furnace wall. When two burners 11a are turned in the same direction and revolution half as much as the circulation of fluid from the nozzles 11a is applied to the remaining burner 11b in an opposite direction, three revolving flows are combined together in the rear part of the flows because of a hydrodynamical effect. The burner 11a carries out a combustion having an equivalent ratio less than 1 and the burner 11b carries out a combustion having an equivalent ratio more than 1. Accordingly, the burner 11a serves as a generating source of NOx and the burner 11b serves as a supply source of a reducing agent such as NH3. When flame from the three burners are finally combined together, NOx is reduced.

Title: Abnormality detection system for signal of periodic wave form
Inventor: YOKOTA KAZUYUKI
IPC: G01R19/175
Filed: 1979-08-15
Abstract: PURPOSE: To accurately judge whether or not there is correlation among the cycles of an input signal whose amplitude and frequency vary slowly, by adopting a cycle correlation find-out system in which a cycle during which data are transmitted is used as a reference cycle.  
     CONSTITUTION: Each preceding cycle of a wave form is not necessarily used as a reference cycle to detect correlation betweent two cycles. A cycle, to which no correlation is detected with regard to preceding cycles, is used as a new reference cycle. Supposing that correlation is detected between a reference cycle (n-th cycle) and the (n+1)-th and the (n+2)-th cycles and no correlation is detected between the reference cycle (n-th cycle) and the (n+3)-th cycle, the (n+3)-th cycle is used as a new reference cycle for following detection of correlation. According to this system, data to which no correlation is detected are surely used as references. As a result, no error integration is caused and it can accurately be discriminated whether or not there is correlation among the cycles of an input signal.

Title: Optical encoder
Inventor: TANIGUCHI MITSUYUKI
IPC: G01D5/30
Filed: 1998-04-01
Abstract: PROBLEM TO BE SOLVED: To improve the strength of a movable code-disc and dispense with the high fitting precision of a metal mold used for formation by forming an optical path changing function by a continued irregular form sufficiently small to the thickness of the movable code-disc. SOLUTION: This rotary optical encoder has a light source part 1 and a light receiving part 2 provided with a movable code-disc 4 in-between, and the light receiving part 2 has two photodetectors 21, 22. The optical path hanging function provided on the movable code-disc 4 is formed of a continued irregular form 42a sufficiently small to the thickness of the movable code-disc 4. Thus, the movable code-disc 4 can have a sufficient strength. In its formation by use of a metal mold, since the coding of light can be performed only by providing the irregular form 42a on either one of the incident side and the emitting side, high fitting precision is not required. Further, since the optical path can be changed by the small irregular form 42a, the movable code board 4 can be manufactured without depending on the signal period.

Title: Switching regulator circuit
Inventor: IKEDA NORIYOSHI
IPC: H02M3/155
Filed: 1979-08-15
Abstract: PURPOSE: To simplify the circuit constitution and at the same time realize a cost reduction, by incorporating the choke coil with the intermediate terminal and others.  
     CONSTITUTION: The choke coil 20 with the intermediate terminal is provided. The current flows through the coil 20 when the transistor TR1 is turned on, and the magnetic energy is stored (a) in the coil 20. And the stored energy is turned into the current flow F when the TR1 is turned off, thus holding the output voltage E at a constant voltage of -5V (b). In this instant, the potential at the observing point D jumps up to such level (positive potetial of value of winding ratio m of E×coil 7) as shown by D. In other words, the potential D becomes to +15V with m=3. On the other hand, the time factor during the ON state of TR1 is controlled so that an equal value may be secured between the upper and lower slant line area centering on the voltage E. Thus an extreme reduction can be avoided for the slant line areas even in such case the ratio between the input voltage and the output voltage is 10/1. As a result, the transformer or the diode can be eliminated in comparison with the conventional constitution, thus simplifying the circuit constitution.

Abstract: PURPOSE:To reduce the rotatory fluctuation of the optical signal transmission in the  adjusting method for an optical rotary joint, by shifting the end face of an optical fiber  in the rotary system side or the still system side from the focus point of a lens. CONSTITUTION:A cylinder 1 which is rotated together with a rotary system is attached  freely rotatably to a frame 3, which is fixed to a still system, by a bearing 4. An  optical fiber 2 connected to the rotary system is fixed to the center of the end part of  the cylinder 1, and a lens 5 is provided in the other end of the cylinder 1 and is so  controlled that the tip of the optical fiber 2 is placed on the focus point of the lens 5.  A lens 6 is provided in a position facing to the lens 5 in the frame 3 and is so adjusted  that the tip of the optical fiber in the still system is placed in a position which is shifted from the focus point of the lens 6 by a length alpha in drawing. An optical connector is eccentric inevitably on the structure, and therefore, the rotatory fluctuation is  generated. However, when the end face of the optical fiber is shifted slightly from the  focus point of the lens, dimensions of the light spot on the end face of the connector  are slightly larger than the diameter of the core of the optical fiber, and thus, the  rotatory fluctuation of the optical signal transmission is restrained low.
