Title: Aircraft
Inventor: MIYAGAWA JUNICHI
IPC: B64C9/36
Filed: 1995-02-23
Abstract: PURPOSE: To provide an aircraft which does not lose the directional steerability even in a large angle of attack by providing a movable outer plate of a body rear part provided openable in the right-to-left direction by a front end hinge and an actuator to be opened at the prescribed opening according to the steering command. CONSTITUTION: A body rudder 3 forms a smooth surface as a part of a body rear part 2a when an aircraft 1 is cruising and the body rudder 3 is stored. On the other hand, either side of the body rudder 3 is pushed out by the prescribed quantity (angle) by an actuator 7 outwardly from the surface of the body rear part 2a around a hinge 8 when the aircraft is steered, and the air force for the balance in the required direction is generated. Though the air force required for the directional steering and the balance is basically generated by a vertical tail 4 and a rudder 5, the complementary air force is generated by the body rudder 3 when the aircraft flies with a large angle of attack. The deteriorated effectiveness of the rudder 5 at a large angle of attack is efficiently complemented by the body rudder 3 making use of the outer plate of the body rear part 2a.

IPC: H04N7/087
Filed: 1991-02-05
Abstract: PURPOSE:To simplify the circuit constitution by selecting an audio data clock frequency to be the integral multiple of a horizontal synchronizing signal frequency of a video signal, compressing an audio data signal for a vertical blanking period of the video signal in terms of time base and sending the compressed signal. CONSTITUTION:An audio inputted at a coder (a) is subjected to high efficient coding (6) and an error checking code(ECC) is added by an ECC adder 7 and compressed in terms of time base by a time base compressor 8. On the other hand, the video signal is clamped by a clamping circuit 1 and an audio data is added to a data insertion location selected in a vertical blanking period by a vertical blanking PCM audio insertion device 3. Thus, the resulting signal is sent as an audio multiplex video signal.

Title: LOW NOx COMBUSTION DEVICE
Inventor: KIKUTANI FUMITAKA
IPC: F23C99/00
Filed: 1999-02-15
Abstract: PROBLEM TO BE SOLVED: To realize low NOx combustion in a condition where combustion ratio of a thin concentration flame is increased or concentration of such a thin concentration flame is further diluted. SOLUTION: A device comprises a thin concentration chamber 11 communicated with a thin concentration flame port 12 and containing mixed thin concentration gas, a first mixed gas chamber 13 being adjacent to the chamber 11 and containing high-concentration mixed gas, a first lame port 14 communicating with the chamber 13 and provided close to the flame port 12, a second mixed chamber 16 being adjacent to the chamber 13 and containing mixed gas, and a second flame hole 17 communicating with the chamber 16 and provided close to the flame port 14. The device is so constructed that the concentration of the gas in the chamber 13 becomes higher than that of the gas in the chamber 16.  Thus, activated chemical spieces which have been produced by thermally decomposing super high concentration mixed gas, which was supplied from the flame port 14, with the high concentration flame above the flame hole 17, are supplied to the base portion of the thin concentration flame port by diffusion to form a 'high temperature/high reaction zone' where combustion reaction is actively performed. In this way, even a large amount of thin concentration flame can be stabilized to realize super low NOx combustion.

Title: Safety device against turning-over of three-wheeled fork lift
Inventor: MATSUDA MINORU
IPC: B62D49/08
Filed: 1981-03-11
Abstract: PURPOSE:To prevent a road face or a car body from being damaged by providing auxiliary wheels which rotate in contact with the road face when the car body is inclined. CONSTITUTION:When a car body is inclined, an auxiliary wheel 11 on the inclined side is rotated in contact with a road face, and the car continues running with a front wheel 2, a rear wheel 3, and the grounded auxiliary wheel 11, thus a stable run is assured without turning-over. Since shocks received from the road face through the auxiliary wheel 11 while running are absorbed by a buffer spring 12, it is unlikely that a fitting bolt 7 is broken under an abnormal load applied to the fitting bolt 7 of a counterweight 6 caused by the shocks or cracks are generated on the car body 8 or a frame, etc., even if the auxiliary wheel 11 is carelessly crashed into a sharp projection on the road face.

Title: Collapsible telephone set
Inventor: IWADATE TAKEO
IPC: H04M1/02
Filed: 1988-02-18
Abstract: PURPOSE:To prevent a damage on a connecting part between a frame and a main casing even if an unnecessary external force is applied to said two members when the former having a transmitter is stretched from the latter for speaking by providing a spring that energizes the frame in closing direction toward the main casing. CONSTITUTION:When the frame 13 is closed into the main casing, first and second engaging parts 40, 41 of the spring 39 engage with a first engaging protrusion 26 of the casing and a third engaging protrusion 34 of the frame 13 itself, and the frame 13 is energized by the repelling elasticity of the spring 39 in the stretching direction from the main casing. Even if an unnecessary force is applied to the frame 13 from the external to open it, the frame 13 can absorve this force thanks to the elasticity of the spring 39, and thus can be protected from being damaged. Also, when the locked state of the frame is released by operating a lock release button, the frame can spring out because of the spring 30, therefore, a button for springing-out is not necessary, and the space that would have been used for the button can be made use of for the internal mounting of parts in the main casing.
