摘要:
There is disclosed a mold protection apparatus of an injection molding machine in which a cross head position and movable mold position are read from a correspondence table, a calculator calculates a thrust force limit value set with respect to a movable mold, and a cross head position controller controls a thrust force of the cross head in the corresponding position via a servomotor, so that the thrust force of the cross head is controlled to indicate a limit value or less in accordance with position of the movable mold.
摘要:
A cross head position corresponding to a movable mold position set by a movable mold position setting unit is read out from a correspondence table, the position of the cross head is controlled by a cross head position controlling unit via a servo-motor, and the position of the cross head is converted into a position of the movable mold, whereby target position setting of the movable mold is achieved.

A wheel balance weight includes a weight and a double-sided tape. The weight is formed as a substantially strip shape, is made from a ferrous alloy, and has opposite top and bottom surfaces and at least a groove. The groove is formed in the bottom surface of the weight, and crosses in the width-wise direction thereof being substantially perpendicular to the longitudinal direction thereof. The double-sided tape has opposite adhesive surfaces being disposed back to back with each other. One of the opposite adhesive surfaces is to be bonded onto the bottom surface of the weight, and the other one of the opposite adhesive surfaces to be bonded onto an inner peripheral surface of a wheel. Accordingly, it is possible to curve the weight with less force. Hence, it is possible to install the wheel balance weight to a wheel with ease.

In a position control apparatus, the rate and the torque of the servomotor are monitored, wherein when it is detected that the servomotor is locked, the torque is limited, so that renewal of a command position to be supplied to the servomotor driving unit is stopped.

In a buckle for a seat belt, lower ends of side walls of an operational button is positioned at a level lower than lower ends of guide portions of a base, and an upper surface of a portion of a lower cover defining a tongue-insertion opening is positioned at a level higher than an upper surface of a bottom of the base. Therefore, when a tongue is engaged with the buckle, an engaging portion of the tongue touches at least one of the side walls of the operational button made of resin, and the portion of the lower cover made of resin. Thus, the tongue is prevented from touching the guide portions and the bottom of the base made of metal, thereby preventing a noise due to the metal-to-metal contact when the tongue 3 is inserted into the buckle and engaged with the buckle. Therefore, a jar on an occupant's nerve when wearing the seat belt can be avoided.
摘要:
Provided is a granular fertilizer coated with a thermosetting resin coating, characterized in that a dissolution rate of the fertilizer is retarded by containing a hydrophobic compound in at least one of the coating portion and the fertilizer portion thereof. The dissolution rate is further retarded than that of a conventional granular coated fertilizer coated with a thermosetting resin.
摘要:
The duty of a current to be supplied to an injection motor is calculated on the basis of the ratio between set injection time for which the injection motor operates and molding cycle time, a shaft torque of the injection motor is calculated on the basis of a set maximum injection force of the injection molding condition, a maximum current for the injection motor is determined on the basis of the calculated shaft torque, and it is decided that the injection motor is overloaded, an alarm is given, a duty for a current that enables continuous molding is retrieved for the maximum current, a state that enables continuous molding is displayed and the molding cycle time determining the duty of the current that enables continuous molding is corrected when the current having the calculated desired duty is smaller than the maximum current.

摘要:
A polyamide resin composition and a biaxially stretched film comprising the polyamide resin composition. The polyamide resin composition comprises (1) 93 to 99.5% by weight of a polyamide resin and (2) 0.5 to 7% by weight of an acid-modified resin, the acid-modified resin being obtained by adding 0.5 to 5 parts by weight of an unsaturated. carboxylic acid to 100 parts by weight of an ethylene-vinyl acetate copolymer having a vinyl acetate content of 20 to 50% by weight partially saponified to have a degree of saponification of 50 to 95 mol %.
摘要:
A steering stability in a pair of pneumatic radial front and rear tires is considerably improved without sacrificing the tire durability by making a circumferential rigidity of an auxiliary belt in the front tire at a portion corresponding to a central zone of a belt in widthwise direction thereof larger than that of an auxiliary belt in a rear tire at the portion corresponding to the central zone of the belt in widthwise direction thereof.
