Title: Defective material distributing method for steel tube
Inventor: OTA ATSUSHI
IPC: B21B38/00
Filed: 1990-10-15
Abstract: PURPOSE:To smoothly execute the operation of a cradle by counting up the generation rate of every classification of failure at every prescribed period, and increasing the number of allocated drop-in devices of every classification in accordance with the generation rate, at the time of distributing automatically a defective material to plural drop-in device at every classification. CONSTITUTION:Results of a non-destructive inspection and a visual observation inspection in on-line of a steel tube are decided synthetically, and a defective material 12 is distributed automatically to plural drop-in devices through a transfer table 14 from on a line 13 at every classification of failure. The generation rate of every classification of failure is counted up at every prescribed period, and in accordance with the generation rate, the number of allocated drop-in devices of every classification is increased and decreased. In such a way, the operation of a cradle 15a (distributing device of every classification of a defect) can be executed smoothly. It is prevented that an unbalance is generated in the operation of the cradle and the line is stopped, and it takes time for classifying the defective material in off-line, as a conventional distributing method for the defective material in which the number of cradles is constant by the classification of the defective material.

Inventor: YOSHIDA MASAMI
IPC: B60N2/08
Filed: 1990-10-15
Abstract: PURPOSE:To prevent foreign matter from being clogged between the upper surface of a car body floor and a bracket resulting in mal-function of an adjusting device by mounting a lock plate so that it surrounds the under surface of a lock mounting bracket welded to the side of a movable rail sliding on a fixed rail CONSTITUTION:In locked condition, a fixing tooth 15 of a lock member 14 is fixed to a fixing hole 13 of a bracket 5 with the tooth 15 projected through a fixing hole 18 of a lock plate 16 toward the inner side of the lock plate 16. Since a main body 12 of the bracket 5 fixed at a movable rail 2 side and the lock member 14 of a lock device 4 are positioned on both right and left side of the lock plate 16 locked at a fixed rail 3 side, movement of the movable rail 2 relative to the fixed rail 3 can be stopped. When a rotational shaft 9 is rotated by an operation lever 11 against an elastic force of a spring 20, the fixing tooth 15 is separated from the fixing hole 18 to unlock and, therefore, the movable rail 2 is moved back and forth to adjust the forward and backward position of vehicle seat.

Abstract: PURPOSE: To economically produce cyclopentadiene which is useful as an intermediate for organic synthesis in a high yield from an inexpensive feedstock by the vapor-phase dehydrative cyclization of a specific unsaturated carbonyl compound in the presence of a solid acid catalyst. CONSTITUTION: This cyclopentadiene of formula II (the broken line in the 5-membered ring shows that the ring may include two double bonds) is obtained by subjecting an unsaturated carbonyl compound of formula I (R1 -R5 are each H, a 1-4C alkyl, axaryl; the dotted line means that there are cases where R1 and R2 bond to each other to form an aliphatic 5- or 6-membered ring) to vapor- phase dehydrative cyclization in the presence of a solid acid catalyst, preferably a HY-type zeolite or hydrogen-form mordenite. It is preferred that the reaction temperature is 250-500 deg.C, the reaction pressure ranges from normal one to 5kg/cm<2> and the contact time of the feedstock with the catalyst is 0.05-5 seconds. 1,3-Dimethylcyclopentadiene is preferred as a compound of formula II because it is obtained in a high yield.

Title: Level conversion circuit
Inventor: WAKAYAMA YASUSHI
IPC: H03K5/02
Filed: 1988-10-31
Abstract: PURPOSE:To prevent current consumption in a fast operation from being increased by providing a PMOS transistor whose gate electrode is connected to an input terminal, whose source electrode to the cathode side terminal of a diode, and whose drain electrode to an output terminal. CONSTITUTION:The gate electrode of the PMOS transistor 4 is connected to the input terminal 1, and the source electrode to the cathode side terminal of the diode 3, and the drain electrode to the output terminal 5. Meanwhile, the gate electrode of an NMOS transistor 6 is connected to the terminal 1, and the source electrode to the anode side terminal of the diode 7, and the drain electrode to the terminal 5. In such a constitution, assuming the potential of a negative power source 8 as 0 and that of a positive power source as VDD, the voltage of the terminal 5 goes to a value less than the VDD by the voltage drop of the diode 3 when the voltage of the terminal 1 is VDD. Also, when the voltage of the terminal 1 is 0, the voltage of the terminal 1 goes to the value larger than 0 by the voltage drop of the diode 3, which reduces the amplitude of the terminal 5, Therefore, it is possible to prevent the current consumption from being increased even in the fast operation.

Title: Linear dc motor
Inventor: ANDO TOSHIYUKI
IPC: H02K41/02
Filed: 1990-10-16
Abstract: PURPOSE:To prevent the destruction of a needle and a device main body by using a magnet which is stronger in magnetic force than field magnets in a reciprocating motion area as a field magnet to be provided on the outside of the reciprocating motion area. CONSTITUTION:Permanent magnets 12a and 12b (hatched magnets) on the outside of the reciprocating motion area L of a needle 1 are formed of a material (strong magnet) having a larger maximum energy product than permanent magnets 12 in the area L have. Accordingly, the magnetic flux density in the gap between the permanent magnets 12a and 12b on the outside of the area L and a mobile back yoke 2 becomes higher than that of the area L. Therefore, the frictional force becomes stronger than thrust on the outside of the reciprocating motion area L and, as a result, even when the needle runs out of control, the needle 1 can be surely stopped and the destruction of the needle 1 and device main body can be prevented.
