Abstract:
A safer safety door, provided at low cost and imposing little burden on an operator. A primary safety door with a top and a secondary safety door are provided on a clamping unit. The primary safety door and the secondary safety door abut each other at abutting portions provided on each safety door. The secondary safety door has an engaging member that swings along a guide member. The engaging member has a hinge bent in one direction. When both safety doors are closed, the primary safety door can be freely opened and closed independently. When the secondary safety door is opened, both safety doors are linked together and move as a single body. In the state where the primary and secondary safety doors are opened separately, when the primary safety door is moved to be closed, the hinge member bends and both safety doors are linked together as a unit.
Abstract:
An internal voltage generator when activated, generates an internal voltage to be supplied to an internal circuit. Operating the internal voltage generator consumes a predetermined amount of the power. In response to a control signal from the exterior, an entry circuit inactivates the internal voltage generator. When the internal voltage generator is inactivated, the internal voltage is not generated, thereby reducing the power consumption. By the control signal from the exterior, therefore, a chip can easily enter a low power consumption mode. The internal voltage generator is exemplified by a booster for generating the boost voltage of a word line connected with memory cells, a substrate voltage generator for generating a substrate voltage, or a precharging voltage generator for generating the precharging voltage of bit lines to be connected with the memory cells.

Abstract:
The invention provides an injection molding machine injection unit that eliminates adverse effects on the load cell of belt tension due to belt drive. A load cell that detects resin pressure is mounted on a pusher plate and a rotation-transmitting member, on which an injection screw is fixedly mounted, is axially supported by an inner annular part of the load cell. The shaft of a pulley is axially supported on the pusher plate and coupled by splines to the rotation-transmitting member. A screw rotation motor is mounted on motor mounts of a housing mounted on the rear surface of the pusher plate. Tension on a belt run between the pulley and a pulley mounted on the motor output shaft concentrates a force at the base of the motor mounts. However, the housing is separate from the pusher plate and fixedly mounted on the pusher plate at a location other than that occupied by the base of the motor mounts. Therefore, the belt tension does not adversely affect the load cell, thus enabling high-accuracy resin pressure detection.

Abstract:
A lubricant supply device that reliably removes air from lubricant such as grease and supplies the grease to an object of lubrication. An air detection sensor that detects air is disposed in a grease introduction hole of a grease transporting path. Grease supplied by a pump passes through the grease introduction hole, a chamber divided by a spool and a grease discharge port, and is introduced into the lubricated parts of a machine. If air in the grease is detected by the air detection sensor, a controller drives a switching valve, moves the spool by pressurized air, and connects the grease introduction hole to an air exhaust port. The air mixed in with the grease is then expelled from the air exhaust port. When the air detection sensor no longer detects air, the controller switches the switching valve, returns the spool to its original position, and discharges grease from the grease discharge port. The lubricant supply device detects and removes air that is mixed in with the grease just before the grease is introduced into the lubricated parts of the machine, and therefore can remove the air more reliably.
Abstract:
A precharge voltage generating circuit outputs any of a plurality of kinds of precharge voltages in accordance with an ambient temperature. A precharge circuit supplies the precharge voltage to a bit line during the nonaccess of a dynamic memory cell. A sense amplifier amplifies a difference between the voltage of a data signal read from the dynamic memory cell onto the bit line and the supplied precharge voltage. The precharge voltage is altered in accordance with the ambient temperature, whereby the read margin of the sense amplifier can be changed, and the worst value of the data retaining time of the memory cell can be improved. As a result, the frequency of refreshing of the memory cell can be lowered, reducing power consumption and a standby current.
