Abstract: PURPOSE:To prevent a multiple car accident with rear-end collisions by fitting a smoke signaling device at the bumper of a car and thereby informing following cars with a colored smoking and flaming signal with a high brightness that the car has applied emergency brakes from high speed running. CONSTITUTION:A car is at its bumper 8 equipped with a smoke signaling device 25 consisting of an electronic lighter 22, a smoking/flaming chamber 23, etc. When brakes are applied during running on a highway owing to coming up to any occurrence of car accident, a lever switch 6 is quickly turned on to release solenoid operated valves 16, 19 from their closed conditions through the action of a battery 3. At the same time, the lighter 22 will momentarily ignite a wick 12 and a colored smoking agent 13 in the smoking and flaming chamber 23 to emit a colored smoking flame 24 with high brightness. Thus following cars are informed surely about an occurrence of car accident ahead, and a chain accident with rear-end collisions can be prevented.

Title: Chattering preventing circuit
Inventor: NAKAYAMA KOUICHI
IPC: H03K5/1254
Filed: 1980-12-09
Abstract: PURPOSE:To simplify a circuit and to avoid the generation of noise, by constituting the circuit only with IIL gate circuits. CONSTITUTION:A current flows from a current source 11 of an I<2>L to the input terminal of the 1st I<2>L gate G1 and a capacitor C is charged. When a switch S turned on, the capacitor C is discharged and the input of the gate G1 is at L level. Thus, the output of the I<2>L gate G2 is also at L level, and the output of  I<2>L gates G3 and G4 is at L level. With this state, a flip-flop consisting of the  gates G3, G4 is set. The chattering when the switch S turns on can be prevented, since the capacitor C maintains the input level of the gate G1. When the  switch S turns off, since the input level of the gate G1 is maintained until the  capacitor C is charged, the chattering can be prevented.

Title: Image forming device
Inventor: TABUCHI KENJI
IPC: G03G15/08
Filed: 1989-07-05
Abstract: PURPOSE:To collect most of developer before reaching a filter and to maintain the performance of the filter for a long time by providing the filter which sucks the air in the vicinity of a part where an electrostatic latent image carrier and a developing device are opposed and decelerates the air. CONSTITUTION:By driving a fan 29, the air in spaces 21 and 25 and a duct 22 is sucked and the air positioned below a developing area X is sucked from the open leading edge part 23 of the duct 22. The air and toner sucked in the duct 22 vertically descends in the duct 22 to be guided to the space 21. The air guided to the space 21 rapidly decreases its speed and moves in a horizontal direction at a low speed to the space 25. Therefore, the toner included in the sucked air drops by gravity in a collecting container 30 during moving to the spaces 21 and 25. The air in the space 25 is discharged to the outside through the filter 27. Since the toner included in the air mostly drops in the space 21 and is collected in the collecting container 30, it is little toner that is caught by the filter 27.

Title: Dew condensation sensor
Inventor: KOBAYASHI KAZUO
IPC: G01N27/12
Filed: 1985-08-07
Abstract: PURPOSE:To rapidly detect dew condensation with good accuracy, by holding an ultrathin insulating film between a pair of electrode plates. CONSTITUTION:An ultrathin insulating film 3 having a thickness of about 7.5mum is held and bonded between a pair of L-shaped electrode plates 1a, 1b bent to reverse directions to form a fine groove 6 surrounded by the mutually opposed surface parts 7a, 7b at the fold parts of both electrode plates 1a, 1b and the end surface 8 of the film 3 and, when a humidity-sensitive agent 9 comprising an org. polymer is applied to the fine groove 6, a humidity-sensitive film with a thickness of about 7.5mum is formed between the electrode plates 1a, 1b. When an atmosphere reaches a dew point, dew condensation is generated on the folded pieces 2a, 2b of the electrode plates 1a, 1b and condensed water is absorbed by the humidity-sensitive film and, because the electric resistance value of the humidity-sensitive film is lowered, a minute current flows between the electrode plates 1a, 1b. Further, since the minute current rapidly flows when even a slight amount of moisture is absorbed because the dimension between the electrode plates 1a, 1b is extremely small as about 7.5mum, dew condensation is rapidly detected.

Single channel display and plural channel display are performed according to the control by the control part 6 in an output driver 5. The setting of the single channel displayed on a display screen is copied to another channel displayed on the same screen by instruction of a copy switch 2.  Therefore, confirmation of the setting, correction of the setting and bi-directional copy of the setting between the channels are enabled by displaying the setting of plural channels on one screen simply by operating the picture changeover switch 1 and the copy switch 2.

Title: Method for melting groove wall by automatic pipe circumference welding equipment
Inventor: MANRAI YUUICHI
IPC: B23K9/09
Filed: 1995-06-19
Abstract: PURPOSE: To provide an automatic circumference welding method of a pipe having excellent quality free from any defective melting or undercut by stopping the weaving at the groove tip for the welding, and realizing a control by the stop signal so that the pulse width during the stop is larger than that during the weaving to increase the arc length. CONSTITUTION: In the melting of a groove wall by an automatic circumference welding equipment of a pipe which achieves the welding by the welding current of the prescribed pulse width while a welding torch is woven in the direction orthogonal to the advancing direction of the welding, the weaving is achieved in the right-to-left direction between the groove walls, not stopped in the middle thereof, and stopped at the right and left ends of the groove. The pulse width is wider at the right and left ends while narrow in the middle. The arc length is large at the right and left ends while it is small in the middle. Because the pulse current and the pulse width are controlled when the welding torch reaches the groove wall in a synchronous manner with the driving pulse of a servo motor for weaving, the groove walls can be continuously melted without stopping the arc.

Title: Injection molding
Inventor: TAKAO MAKOTO
IPC: B29C45/52
Filed: 1990-07-03
Abstract: PURPOSE:To prevent a molding material from counterflowing after the commencement of injection by bringing a screw back to the measuring completion position during an interval from the completion of a measuring process to the commencement of an injection process, and placing a counterflow preventing ring into contact with a seal ring. CONSTITUTION:In a measuring state, since a counterflow ring 12 is in contact with the rear end surface of a screw head 3 and thus a clearance is formed between its end and the a seal ring 14, a molding material can freely move therein. When an injection process starts, a screw 2 is made to once retreat at only a set distance of l. The set distance is sufficiently established, when the screw 2 is once stopped and laid at the measuring completion position, in order for the counterflow preventing ring 12 to move rearward and come into contact with the seal ring 14. Namely, when the screw 2 is made to retreat at only a distance of l and advance to be in the measuring completion position, the counterflow preventing ring 12 comes into contact with the rearward seal ring 14. Accordingly, at the measuring completion position, a perfectly sealed state becomes accomplished between the counterflow preventing ring 12 and the seal ring 14 and, as injection is started, no molding material become to counterflow rearward.
