Title: Melt crystallization of wall surface falling type
Inventor: OKUYAMA MANABU
IPC: C07C39/16
Filed: 1998-01-08
Abstract: PROBLEM TO BE SOLVED: To enable the purification of a crude liquid organic compound in a higher purity by reduced steps comprising depositing the thin crystal film of the highly pure liquid organic compound on a wall surface as a seed crystal and subsequently supplying the crude liquid organic compound to the wall surface to grow the crystal. SOLUTION: The thin crystal film of a highly pure liquid organic compound is preliminarily deposited on a wall surface as a seed crystal, and the crude liquid organic compound is supplied to the wall surface to grow the crystal. Concretely, for example, 1,4-butanediol having a purity of 100% and supplied into a storage tank VI is circulated to a crystallization device 1 to wet its wall surface, and the circulation is stopped. A cooling medium cooled at a temperature not higher than the freezing point of the 1,4-butanediol is supplied to crystallize the thin film on the wall surface 2. Crude 1,4-butanediol is further supplied from the storage tank VI to the crystallization device 1 to flow down and simultaneously cool the supplied crude 1,4-butanediol on the wall surface 2.  The deposited crystal is subsequently melted with a heating medium obtained by heating the cooling medium at a temperature not lower than the melting point of the crystal, and recovered.

Title: Normal and reverse rotation switching circuit for motor
Inventor: NISHIJIMA HIDEO
IPC: H02P6/08
Filed: 1982-01-13
Abstract: PURPOSE:To eliminate the conduction of an excess pulse current through a drive transistor by performing the normal and reverse rotation switching within a motor drive current interrupting period. CONSTITUTION:When the rotating direction of a motor is switched from normal to reverse direction, a normal and reverse rotation switching signal voltage 27 varies from ''L'' to ''H''. Then, a level discriminator 25 is turned OFF only during the period T1 that the voltage 27 passes through arbitrarily set voltages a, b. Thus, a switch 26 is opened, the circuit of a battery 22 is turned OFF, and no current flows through a motor during the period T1. A motor drive signal generator 23 applies normal or reverse drive waveform to transistors Q1-Q6 in response to the polarity of the voltage 27. In this manner, it can prevent an excess current from flowing to the motor drive circuit when the rotating direction of the motor is switched over.

Abstract: PURPOSE:To surely release the locking of a motor by moving by a solenoid the lever member pivotally supported so that the force in the direction that the projection meshed with the gear of a motor comes off from the gear may act at the time when a motor is reversely rotated. CONSTITUTION:This mechanism is provided with the lever member 4 pivotally supported so that the force in the direction that a projection 3 comes off from a gear 2 may act at the time when a motor 1 is reversely rotated in the state of this projection 3 being meshed with the gear 2 of a positive and reverse rotating motor 1 by having it at one end and the solenoid 6 moving the lever member 4 in the direction that the projection 3 comes off from the gear 2 by reacting to a driving signal. The force in the direction that the projection 3 comes off from the gear 2 is therefore acted at the reverse rotation time of the motor 1 and the projection 3 attains the state of being easily slipped out. The lever member 4 is easily moved by driving the solenoid 6 and the projection 3 is separated from the gear 2. The locking of a motor can thus be surely released.

Filed: 1981-01-13
Abstract: PURPOSE:To prevent a shutter blade and a rotor from bounding when an electromagnetic driving shutter is fully opened, by braking the rotor through the operation of the magnetic field of the electromagnetic driving shutter when the shutter blade is opened almost fully. CONSTITUTION:As a shutter blade 10 in a closed state is opened in accordance with the rotation of a sector ring 6 through release operation, a magnetic body 16 provided to the sector ring 6 is attracted by a permanent magnet 1. Then, the sector ring 6 rotates and, at the same time, moves down and its lower end surface comes into contact with the permanent magnet 1, so that the sector ring 6 rotates while decelerated with frictional force f2 near a fully-opened position. Further, when the sector ring 6 meets a stopper 8, it bounds and tends to move  in the opposite direction, but the bound of the sector ring 6 converges rapidly through the operation of the frictional force f2. Thus, the bound of the shutter blade in the fully-opened state is prevented.
