A hydraulic braking pressure control apparatus for an automotive vehicle includes a master cylinder mounted on a brake booster for applying a braking force, a master cylinder reservoir provided on the master cylinder for supplying hydraulic fluid to the master cylinder, and a solenoid valve body mounted on the master cylinder. The solenoid valve body includes a plurality of solenoid valves and a fluid circuit operatively connected to the master cylinder for generating a braking pressure to be supplied to wheel brake cylinders. A pump body is mounted on the master cylinder and includes a pump device for returning hydraulic fluid to the master cylinder and the solenoid valve body. A pump motor drives the pump device, with the pump motor being mounted on the master cylinder and being symmetrically disposed with respect to the solenoid valve body.

A machine tool control system and method are provided that utilize metal mold arrangement information to improve machining efficiency and control. According to the disclosure, a machining schedule, a machining program and metal mold information (indicating the characteristic properties of a metal mold to carry out machining) are transferred to a controller for controlling a CNC device and a machine tool unit (e.g., a turret punch press). The controller transfers the metal mold information for the machining program to the CNC device by a different transfer route than that of the machining program. The CNC device searches for a metal mold specified by the metal mold information based on metal mold arrangement information stored in a file. The metal mold arrangement information indicates each metal mold that is located in the machine tool unit. If a specified metal mold is not present, a metal mold exchange instruction is issued so that the specified metal mold may be set in the machine tool unit to carry necessary machining operations.

A workpiece identifying method is provided, being characterized in that a plurality of identification areas of plural columns and rows are plotted in an identification mark providing region provided in the area of the unused portion of a workpiece or a product, identification holes are formed in the proper number of identification areas, whereby an identification mark is provided to the workpiece or the product. A workpiece is produced with identification holes formed in the proper number of identification areas. An identifying method for detecting the identification holes formed in the proper number of identification areas of the workpiece and workpiece identification apparatus are also provided. Sheet metal machining apparatus is further provided, having the workpiece identification apparatus placed in a workpiece feed device side or a carry-away device side for a sheet metal work machine. Thus, an identification mark is easily and surely provided to the workpiece, making it easy to identify the same.
摘要:
When a machining program copied from the toll center is transferred to the NC device, the transfer system determining means of the controller compares a machining schedule copied from the toll center and its machining program with transfer judging rules created in the database to automatically judge whether memory transfer or DNC transfer system is more suitable, and the machining program transfer means transfers the machining program to the NC device by the selected system.
摘要:
An animal rearing apparatus includes an animal rearing cage and a framework to which a plurality of side plates together forming the periphery of the animal rearing cage are detachably attached. At the bottom of the animal rearing cage, there are provided a bottom plate detachably attached thereto and defining a plurality of openings vertically extending therethrough and an excreta collecting portion for receiving and collecting animal excreta dropped through the openings of the bottom plate. The animal rearing cage has a ceiling thereof sectioned by a top plate or the excreta collecting portion belonging to an animal rearing cage on the upper stage. The framework or an attachment member thereof includes, at portions thereof corresponding in level to the ceiling of the animal rearing cage, engaging portions for detachably engaging and suspending engaged portions provided at upper portions of the respective side plates.
摘要:
A piston for a cylinder device which is formed of fiber glass strengthened resinous material and includes a concave portion, where a plug may remain, formed on an end thereof. The piston is engageable with a push rod and in particular an end surface of the push rod. The concave portion may be formed on approximately the center portion of the end concave surface of the piston and may be of circular configuration. Correspondingly, the concave portion may be formed on a flat surface of the end surface of the piston.
