Title: Production of aluminum alloy
Inventor: KUNITOMO HARUO
IPC: C22C1/02
Filed: 1992-12-08
Abstract: PURPOSE:To produce an Al alloy having a low impurity content in a high yield by electrolytically reducing an oxide or fluoride of a rare earth element using the cathode of molten Al that is floated on a molten salt electrolytic bath and the anode, the periphery of which is protected by an insulating material. CONSTITUTION:A molten electrolytic bath 3 is placed in a crucible 5 made of graphite, etc., which is provided with a coating 8 of an insulating material such as PBN. The bath 3 consists essentially of an alkaline or alkaline earth metal fluoride and a fluoride of a rare earth element. The anode 2 such as a carbon rod is dipped in the bath 3 and provided around it with a protecting tube 4 made of the insulating material. The protecting tube 4 is made of boron nitride and is a hollow tube fitted with a vent on its upper part. Thereafter, Al 1 is supplied around the protecting tube 4 and floated on the bath 3 in a molten state. An about 5 to 20 V voltage is applied between the Al 1 used as the cathode and the anode 2, then the oxide or fluoride of the rare earth element supplied into the bath 3 is electrolytically reduced. Thus, the rare earth element-Al alloy having low contents of impurities and inclusions can be produced.

Title: Abnormality detection device of internal combustion engine
Inventor: KATO YASUHIRO
IPC: F02D17/00
Filed: 1998-11-19
Abstract: PROBLEM TO BE SOLVED: To prevent erroneous detection of an impossible actuating condition of an actuator due to shutoff of electric power to the actuator as abnormality at the time of switching off a kill switch. SOLUTION: Abnormality detection of an actuator such as an ignition coil, an injector, a main relay, etc., is carried out only at the time when a kill switch for emergency stop provided independently from an ignition switch is in an ON state, whether electric power voltage is higher than specified voltage required for normal motion of a system or not is judged (step 101, 102) and these two conditions are established. When any of the actuators is judged abnormal, this abnormality is indicated by an alarm lamp, etc., and this abnormality information is memorized in a backup RAM. In this case, as abnormality detection of the actuator is prohibited at the time when the kill switch is switched off, it is possible to prevent erroneous detection as abnormality of the actuator at the time when the kill switch is switched off.

Title: Flow control valve
Inventor: MORI KAZUNORI
IPC: F02M35/10
Filed: 1999-11-19
Abstract: PROBLEM TO BE SOLVED: To provide an inexpensive flow control valve with a simple structure and high durability which can attain a device causing no high frequency abnormal noise by suppressing air turbulence on a downstream side of a throttle valve as a generating source of high frequency turbulence. SOLUTION: A fluid passage 4 of a flow control valve 1 on a downstream side 5 of a throttle 9 is so structured that a fluid flowing assisting member 10 is arranged from the vicinity of the downstream side of a throttle valve 20 toward the downstream side, and a partition wall 12 is arranged on a wall surface 11 opposed to the throttle valve 20 on the downstream side of the assisting member 10, so as to be widened along the flow. It is thus possible to suppress generation of spiral flow due to air turbulence caused by flow of injected air which is adjusted in its amount along the assisting member 10. Even when the injected flow is struck against the wall surface 10, the air turbulence is suppressed by streamlining through the partition wall 12, for reducing high frequency abnormal noise.

Title: Powered adjustable cloth hanger
Inventor: AA FUU RAMU
IPC: A47G25/44
Filed: 1990-11-30
Abstract: PURPOSE: To provide a hanger of which hanger arm length is adjustable to the required size by providing a drive mechanism to move extension arms to advance inward or outward simultaneously and for the same quantity to a support arm. CONSTITUTION: Extension arms 6 are set at the most retracted positions, and a control button 84 is operated to close a switch 80 to energize a motor 16. A pinion gear 18 is rotated to rotate a shaft 36 through a bevel gear 34 to rotate a worm gear 38. The worm gear 38 drives a rack gear 70 to move the extension arm 6 to slide outward from a support arm 2. As the button 84 is released, its move is stopped. As a button 86 is operated, the motor 16 is rotated in the opposite direction to move all the mechanism in the opposite direction. As the extension arm 6 is extended completely, a stopper 92 collides with a return stopper 94. This stops the worm gear 38, shaft 36, and bevel gear 34. In the case where the motor 16 is still energized, a crown gear 24 skips from engagement, and the whole body of a gear 22 is moved upward.

Title: Printing unit cylinder for rotary printer
Inventor: BUERUNAA UEBAA
IPC: B41F27/12
Filed: 1990-11-30
Abstract: PURPOSE: To guarantee an effective vibration absorption in an area of a cylinder gap by dividing a gap strip into individual areas by a slit extended laterally, and allocating the slit of a longitudinal direction to the area so that a profile of the strip is elastically jumped up at the time of bringing two gap strips into contact with one another. CONSTITUTION: Slits 15, 16 of a longitudinal direction are allocated to individual areas in the longitudinal direction of a gap strip 7, and respective lengths are calculated according to a predetermined supporting pressure. A slit 13 extended in a lateral direction is brought into contact with the slit 15 of the longitudinal direction, and hence a profile 17 of the strip 1 can be elastically jumped up by itself. At a terminating area 18, the slit 16 of the longitudinal direction is longer than an intermediate of the strip 7, and hence a supporting pressure is lowered. The profile 17 can be self-adapted to a warp of a cylinder. Since two cooperative gap strips 7, 11 are projected before a midline of the two cylinders 1, 3, the pressure is accumulated before tee cylinder gap so that a disadvantageous vibration is avoided.

Title: Data deciding circuit
Inventor: KAMIYAMA TADAAKI

Filed: 1987-12-25
Abstract: PURPOSE:To eliminate noise component simply and to generate a change pulse corresponding to a prescribed data and an input data even if a noise signal below n-clock as the result of pulse check is superimposed onto the input data by adding a latch circuit between a pulse check circuit and a differentiation circuit. CONSTITUTION:With an input data is at 'H' at first, an output I of a pulse check circuit 1 goes to 'H' with a delay of n-clock if no change exists during n-clock. The signal at the output I sets a latch I circuit 5 to 'H', a differentiation I circuit 2 generates a change pulse to reset a latch III circuit 4 and a latch II circuit 6. When an input data changes to 'L', an output II of the pulse check circuit 1 goes to 'H' with a delay of n-clock to set a latch II circuit 6 to 'H', a differentiation II circuit 3 generates a change pulse to reset a latch III circuit 4 and a latch I circuit 5 respectively. If the noise below n-clock is superimposed on the input data, even if the output of the pulse check circuit 1 is changed, the output is unchanged when the latch II circuit 6 (or latch I circuit 5) set once at the preceding timing, and no excess change pulse is caused.
