Title: Combustion apparatus
Inventor: NISHIKAWA MAKOTO
IPC: F23N5/24
Filed: 1982-04-30
Abstract: PURPOSE:To prevent the generation of smoke and malodor in case of the stoppage of combustion by sucking liquid fuel in a nozzle and a fuel piping to the nozzle when combustion is stopped and preventing the dropping of liquid fuel to a combustion chamber. CONSTITUTION:When a combustion stop signal is emitted, a closing valve 9 is opened, and a jet pump 7 is connected to a fuel tank 6 through a fuel suction pipe 8. On the other hand, a fuel pump 1 continues to be operated for an arbitrarily set time even after the combustion stop signal is emitted. Consequently, liquid fuel ejected to the jet pump 7 from an injection port 7a flows into the fuel tank 6 through a fuel suction pipe 8 from a discharge port 7c, generates negative pressure in the fuel piping 4 to the nozzle 2, and liquid fuel in the nozzle 2 and the fuel piping 4 to the nozzle 2 is sucked to the jet pump 7 from a suction port 7b to stop combustion, and returned to the fuel tank 6. Accordingly, the generation of smoke and malodor in case of the stopppage of combustion can be prevented, and abnormal combustion, such as the unexpected ignition, smoking, etc. of liquid fuel infiltrating into refractory materials, etc. can be obviated.

Title: Cable inserting position detector
Inventor: TANAKA HIROTSUGU
IPC: G01B17/00
Filed: 1999-03-19
Abstract: PROBLEM TO BE SOLVED: To obtain a stable detecting performance without being affected by the material of a connecting tube and irregularity of the connecting tube surface, by providing a probe to send and receive an ultrasonic wave, a means of generating a moving signal, stopper and a probe moving scanner. SOLUTION: A probe 18 to send and receive an ultrasonic wave is provided as a means of detecting existence of a cable 2. If a pulse-shaped transmitting signal is applied to the probe 18 from the transmitting part 12 of a detector body 11, the ultrasonic wave is transmitted from the probe 18, is permeated into a connecting tube 1 through a coupling medium, is returned back to the probe 18 by being reflected by the inner surface of the connecting tube 1 and is received as a boundary surface echo. If the cable 2 exists, the ultrasonic wave is permeated into stranded wires 2a, is returned back to the probe 18 by being reflected at the boundary of plural stranded wires 2a and is received as a bottom surface echo.  Accordingly, a gate marker formed in a gate part 14 is set at the rear of the boundary surface echo, and the existence of the cable 2 can be detected by sensing the bottom surface echo of the stranded wires 2a.

Title: Multi-blade blower
Inventor: KINOSHITA KANJIRO
IPC: F04D29/28
Filed: 1994-04-13
Abstract: PURPOSE:To lower noise from a multi-blade blower and to enhance the blowing function by bending each of blades on an impeller at its axial middle position in the thicknesswise direction, and by inclining a downstream blade part and an upstream blade part rearward in the direction of rotation of the impeller, from the bent position and toward the bent position. CONSTITUTION:Each of blades 4 on an impeller 3 which are supported at its one end 4a to a main board 5 and at the other end to a side board 6, is bent thicknesswise at an axially middle position so as to form a downstream blade part 4A, and an upstream blade part 4B. Further, the downstream blade part 4A and the upstream blade part 4B are respectively inclined rearward in the direction of rotation of the impeller 3 from their one end thereof to the bent position 4c. Accordingly, breakaway of an air-stream from the end edge side of the upstream blade part is restrained, and accordingly, air can smoothly flow from the end edge side of the upstream blade part 4A, and then obliquely flows in a short flow line length on the blade 4 along the rear edge side in the direction of rotation. With this arrangement, it is possible to lower noise from the multi-blade blower, and to enhance the blowing function.

Title: Manufacture of medium-or low-carbon ferromanganese
Inventor: YAMAMOTO KOTARO
IPC: C22C33/04
Filed: 1986-03-31
Abstract: PURPOSE:To obtain medium- or low-carbon ferromanganese more economically than by conventional decarburizing processes, by subjecting molten high-carbon ferromanganese to blowing with dividing the process into two stages, the former stage of higher decarburizing oxygen efficiency and the latter stage of lower decarburizing oxygen efficiency, and by adding Mn oxides and reducing agents in the course of the above stages so as to control the amount of Mn in the molten metal. CONSTITUTION:The molten high-carbon ferromanganese usually of about 1,300-1,400 deg.C is decarburized by means of top blowing of O2 gas and bottom blowing of O2 gas and inert gas until C concentration comes to about 2%. Then top blowing of O2 into the molten metal after the above decarburizing treatment is stopped and, with combining bottom blowing of O2 gas with bottom blowing of inert gas, decarburization is continued until the desired C quantity is reached. At this time, the ratio of the amount of O2 gas to the amount of inert gas is reduced according to the progress of decarburization. Moreover, Mn oxides and reducing agents are added to the molten metal in the course of the above two stages and/or after the conclusion of the latter stage. In this way, the progress of decarburization can be effectively controlled, so that medium- or low-carbon ferromanganese can be obtained more economically than by conventional silicide process or other oxygen-decarburizing processes.

Title: Transmitter-receiver for radar
Inventor: ISHIKAWA MITSURU
IPC: G01S7/34
Filed: 1995-03-31
Abstract: PURPOSE: To obtain a transmitter-receiver which can ignore the influence of an unwanted signal such as a jamming signal, a crack signal or the like by a method wherein an RF low-noise amplifier, a power supply which applies a voltage to the RF low-noise amplifier and a local signal to a mixer are cut off when an ANL circuit is operated. CONSTITUTION: When an ANL circuit 12 is operated, an unwanted signal which has been received by an antenna 2 is passed through an RF low-noise amplifier 4, an RF front 1 and an IF amplifier 11 so as to be input to the circuit 12. Since it is not possible to sense only a regular reception noise, it is possible to prevent a gain from being set erroneously, and it is possible to perform an automatic noise level control operation precisely. That is to say, by an ANL operation signal 15 from the circuit 12, switches 14-S1, 14-S2, 14-S3 inside a switch module 14 are turned off, a voltage to the amplifier 4 and an amplifier 8 which constitute an active transmission-reception module Mn and a local signal to a mixer 9 are cut off. As a result, the unwanted signal is suppressed, and only a noise which is generated by a reception system can be sensed by the circuit 12.
