Patent JP-H09270346-A (JP)
Title: Rare-earth permanent magnet
Inventor: INABA ISAO
IPC: C22C38/00
Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To improve mechanical strength and corrosion resistance, by a method wherein etching treatment is conducted using an acidic solution having pH in a specific range in order to remove the modified layer formed on the surface of a magnet body during mechanical processing, and after removal of the generated smut, a resin film in a specific thickness is provided. SOLUTION: The surface of this rare-earth permanent magnet is etched using an acidic solution of pH 1 to 4. When etching treatment is conducted in the range of pH 1 to 4 as shown in the diagram, the corrosion resisting effect of the enchant is improved by about 20 times, but the corrosion resisting effect is only about twice with pH 5. Then, the smut on the surface is removed by conducting ultrasonic washing in the aqueous solution which is mainly composed of sodium hydroxide. After wishing by a solvent if necessary, an oxidation resistant resin layer is covered on the surface of the magnet. The practically desirable thickness of this layer is 5 to 80μm. As a result, the permanent magnet can be used for the field where high corrosion resistance is required.

Title: Automatic light path compensating mechanism for optical surveying instrument
Inventor: OKAMURA HIRONORI
IPC: G01D11/00
Filed: 1987-03-31
Abstract: PURPOSE:To prevent an attracting action from being generated between a movable member and a stopper member by fixedly mounting the stopper member for restricting the rocking of the movable member constituting the automatic light path compensating mechanism of an optical surveying instrument to its body via a vibratory substance. CONSTITUTION:When a power supply 118 is applied to the oscillator 117 of a vibratory body portion 11 by a single-pole single-throw switch, a vibrating plate 111 and also a stopper member 150 connected to it vibrate. On the other hand, when a telescope body 10 is largely inclined, a movable member 140 constituting an automatic compensating mechanism also rocks through the same inclination as that of the telescope body 10. As soon as the tip of the projection 142c of a portal strut 142 integrated with the movable member 140 abuts against the inner circumferential surface of the stopper member 150, the projection 142c is flipped by the vibration of the member 150. Thus, no attracting phenomenon is generated between the projection 142c and the member 150. Therefore, the movable member 140 integrated with the projection 142c is placed in a condition wherein it is always suspended to be able to rock.

Abstract: PURPOSE:To enable the temperature control for a cooling apparatus, in which a boiled and vaporized liquidous refrigerant is used for cooling every part of an engine, to be accomplished quickly and with high accuracy by forcing the liquid level of the refrigerant in a condenser for condensing the refrigerant vapor to come up and down. CONSTITUTION:When an engine is in operation, and the temperature of a liquidous refrigerant within a water jacket 2 reaches a target temperature, a refrigerant feed pump 4 is driven to discharge some of the liquidous refrigerant from a condenser 3 into a reservoir tank 21. Thereby, boiling under reduced pressures is generated within the water jacket 2, and when the refrigerant level within the water jacket 2 is caused to fall short of a preset level for the first liquid level senser 32 by such boiling, a three-way solenoid valve 16 is switched to a flow passage 13, and a liquidous refrigerant is supplied from a lower tank 13 to the water jacket 2. In addition, when the detected temperature is at more than the target temperature, the three-way solenoid valve 16 is switched to a flow passage A, and the refrigerant level within the condenser 3 is caused to come down. And, in the case contrary to this, the refrigerant level is caused to come up.
