Title: Driving device for disk-like recording medium
Inventor: KATAYAMA TOMOYUKI
IPC: G11B19/22
Filed: 1989-11-20
Abstract: PURPOSE:To speedily stop a disk before it moves to backward rotation by stopping the backward rotation driving of the disk when the order of mark detection outputs by means of two sensors changes from normal rotation to inverse rotation. CONSTITUTION:When a stop command is inputted from an operation circuit 32 to a controller 31 in a state where the disk 22 normally rotates, the command is transmitted to a servo circuit 26 and a motor driving circuit 25 is switched from the driving of normal rotation to backward rotation. Thus, control operates to a disk motor 21 and the number of the rotation of a disk 29 suddenly drops. When the circuit 26 recognizes that the pulse width of slit detection outputs by the sensors 30a and 30b comes to be more than a prescribed value, the command of backward rotation driving from the circuit 26 to the circuit 25 is stopped at that time and the disk 22 stops. Thus the disk can immediately be stopped before the disk 7 backwardly rotates.

Title: Seawater desalination method and device thereof
Inventor: MORI MASATO
IPC: C02F1/14
Filed: 1994-11-11
Abstract: PURPOSE: To attain desalination of seawater by heating the seawater surface in a vapor tank covered with a covering material transmitting sunlight, leading the water vapor into a condenser tank arranged in the sea for exchanging heat for surrounding seawater, and leading the condensed water to a fresh water storage tank on the sea surface. CONSTITUTION: The seawater surface 2a in a vapor tank 1 covered with a covering material 4 is heated by sunlight, water vapor is generated in the tank so as to raise pressure in the tank 1, and the water vapor flows in a condenser tank 5 in the sea through a steam pipe 7. Next the water vapor is cooled and condensed to be fresh water, and stored in the tank 5. In this case pressure in the tank 5 is lowered by the condensation of water vapor, further vapor in the tank 1 flows in the tank 5 and becomes fresh water by condensation, and stays in the tank 5. A submergible pump 8 is driven keeping pace with this, fresh water in the tank 5 is in order sent to a floating type fresh water storage tank 11 on the sea surface, and stored therein.  Such operation is carried out continuously and in parallel, seawater is gradually changed to fresh water and stored in the tank 11, and the fresh water is taken out and sent to the land as occasion demands.

IPC: B60R9/048
Filed: 1997-11-04
Abstract: PROBLEM TO BE SOLVED: To provide a lock structure for a roof box whereby in the case of performing key operation, insufficiency of a closed condition of a box cover can be recognized. SOLUTION: In a lower end of a lock part 8, a down-facing protrusion part 12 positioned in one end side of a lock groove 11 is formed, consequently a closed condition of a box cover is temporarily insufficient, even when a position of the lock part 8 comes to be higher than a regular position, a bending part 18 of a lock plate 19 rotated by key operation interferes with the protrusion part 12 in the vicinity of one end side of the lock groove 11, by impeding any more rotation, by this fact, the closed condition of the box cover can be recognized to be insufficient by a key operator, the box cover can be placed newly in a surely closed condition.

Title: Granular preparation for mri
Inventor: NAKAGAMI HIROAKI
IPC: A61K49/18
Filed: 1992-11-13
Abstract: PURPOSE:To provide the granular preparation capable of being readily dispersed in water to give a uniformly viscous dispersion as an administration form by processing oral administration ferromagnetic particles for MRI diagnosis into a particulate preparation of suspension type on its employment. CONSTITUTION:A thickening agent is granulated together with a binder and, if necessary, with an excipient, a disintegrator, etc., by a fluidized bed granulation method into granules. Ferromagnetic particles are suspended in an aqueous solution of the thickening agent or hinder and subsequently spray-coated on nuclear granules preliminarily produced by granulating the abovementioned additive or added to the additive on its granulation. The granular preparation of the ferromagnetic particles does not generate its coagulation caused by its gelation when suspended, and instantly gives a uniformly viscous suspension only by agitation. An agent for MRI is prepared by a simple preparation method. Since the granular preparation is a solid preparation, the granular preparation is excellent in the stability of the ferromagnetic particles in comparison with a water dispersion preparation, does not require an anxiety for its rot caused by microorganisms or fungi, and is advantageous also in the aspects of transportation and storage space.

Abstract: PURPOSE:To suppress a useless dialing by detecting a dial inhibit signal from an opposite party in the communication equipment provided with an automatic dialing function. CONSTITUTION:A control circuit 52 of a facsimile equipment discriminates whether or not an automatic dialing destination is a telephone set disabling facsimile transmission reception through the detection result by a voice detection circuit 38, an RBT detection circuit 34 or a BT detection circuit 36. When the opposite party is discriminated to be a telephone set, it is displayed by a display circuit 42 to inform it to the operator and sets a telephone set flag to a dial storage circuit 46 thereby inhibiting succeeding redialing to the destination. Moreover, when a dial inhibit request comes from the opposite party, a redial inhibit signal detection circuit 32 detects it to inhibit succeeding dialing. Thus, it is prevented that useless dialing is sent to the opposite party.
