Title: Combustion gas burner within pipe
Inventor: MITSUTOMI HIROYUKI
IPC: F23D14/12
Filed: 1979-04-13
Abstract: PURPOSE: To enable combustion of a gas burner with high load and improve the strength of the gas burner against vibration or others by an arrangement wherein a throttle plate is provided between the primary and secondary combustion chambers, a swirling air inlet is provided in the secondary combustion chamber near the throttle plate, and the primary combustion chamber is formed in a cone shape.  
     CONSTITUTION: Fuel gas supplied from a gas conduit 3 enters into a gas header 6 of a primary combustion chamber 10 and then is injected from a gas injection port thereof. While primary and secondary airs enter thereinto through a primary air port 4 and a secondary air port 5, respectively. In this occasion, one part of the primary air enters into the primary combustion chamber 10 through air ports 8, another part of the primary air through air ports 11 provided in a cone 7, and the rest of the primary air through a gap between the cone 7 and a throttle plate 9, respectively. Air tangentially supplied from the secondary air port 5 into a secondary combustion chamber 12 is swirled therein and forwarded to the outside of the throttle plate 9. By so doing, there is caused partial combustion in the primary combustion chamber 10 and secondary combustion in the secondary combustion chamber 12, thereby absorbing pressure vibration within a pipe by the throttle plate 9.

Title: Failure diagnosing device for fuel evapotranspiration preventing device
Inventor: AZUMA TADAHIRO
IPC: G01M3/28
Filed: 1996-03-04
Abstract: PROBLEM TO BE SOLVED: To diagnose failure with high accuracy by closing a purge control valve and an atmosphere hole when fuel tank inner pressure attains a target pressure so as to form an enclosing zone in a fuel evapotranspiration preventing device, and diagnosing failure on the basis of the change of the inner pressure in the enclosed zone. SOLUTION: Firstly, a purge valve 23 is closed, an atmosphere hole 21 is opened by an atmosphere hole opening/closing valve 22 while eliminating negative pressure from an intake pipe 7 so as to wait that inner pressure of a fuel tank 15 is increased to a initial pressure. When inner pressure in the fuel tank 15 attains initial pressure, the atmosphere hole 21 is closed, the purge control valve 23 is driven so as to open a purge. Inner pressure of the fuel tank 15 is reduced gradually. When it attains a prescribed target pressure, the purge control valve 23 is closed, and the fuel tank 15, a purge passage 18, and a canister 20 are enclosed. The lowest pressure in the enclosed zone and a comparative referential value which is set beforehand are compared with each other, failure is diagnosed when the value of the lowest pressure is larger than the comparative referential value.  The comparative referential value is set in an intermediate value between the lowest pressure in the enclosed zone when a system is in a normal condition and the lowest pressure when the system is failed.

Title: Ultrasonic vibration cutting device
Inventor: MORI EIJI
IPC: B23B29/12
Filed: 1982-03-25
Abstract: PURPOSE:To aim at making an ultrasonic vibration cutting device a still higher output one, by supporting a bending vibration web part of the ultrasonic vibration cutting device which operates for a bending vibration, with a pair of vertical vibro-resonant supporters, while attaching ultrasonic vibrators to the paired vibro-resonant supporters as the constitution of this device. CONSTITUTION:When a signal commensurate to the bending vibration frequency of a cutting tool 2 is impressed on each of ultrasonic vibrators 4a and 4b, these vibrators 4a and 4b make vertical vibrations which are transmitted to the cutting tool 2 via vertical vibro-resonant supporters 7a, 7c. In this case, since both supporters 7a and 7c are positioned each at the position of each bending vibration web part of the cutting tool 2, the vibration is excited in the tool 2. Likewise, supporters 7b and 7d are both positioned at the position of each bending vibration web part of the tool 2 respectively whereby the tool's vertical vibration is excited. When these vibrators are connected to each of supporters 7b and 7d, their ultrasonic driving forces can be stepped up. With the constitution like this, a supporting structure to a heavy load is strengthened as well as a still higher output can be secured.

Title: Device for removing chip for running circular saw
Inventor: WATANABE TAMIO
IPC: B27G3/00
Filed: 1990-02-27
Abstract: PURPOSE:To prevent chips from scattering, preventing thereby the environment from being harmed and preventing a workpiece from being damaged by providing a running groove for a circular saw in the longitudinal direction of a press plate and a cavity communicating with said groove, and connecting a vacuum means provided with a suction port which is opposed to the surface of a placing ruler board to the lower end of said cavity. CONSTITUTION:When a workpiece W is secured to a work table 3 by means of a press plate 40 and a circular saw 26 is caused to run, with the saw protruding from a slit 6 which allows the saw to run therethrough, the workpiece W is cut by the saw 26. Since the saw 26 cuts the workpiece W by up-cut method, with its ends of saw blade protruding from the surface of the workpiece and facing a running groove 47, most of chips are discharged into a collection cover 32 and discharged to a vacuum means from a suction port 32a, while part of the chips get into a cavity 48 of the plate 40; however, they fall onto a receiving surface 10a of an auxiliary ruler board 10 and are discharged to the vacuum means through a suction port 49. In this manner, the chips are not scattered by the turbulence of air flow caused by the saw during the cutting operation.
