Abstract: Problem to be Solved Provided is a packing box that enables to easily release a slit lock in which slits of an insertion piece of an openable lid engage with side flaps connected to openable lid side edge portions of lid side members, even if the interior of a box body of the packing box is tightly filled with a product.

Abstract: A packing box enables easy release a slit lock in which slits in an insertion piece of an openable lid engage side flaps connected to openable lid side edge portions of lid side members, even if the interior of a box body of the packing box is tightly filled with a product. The top face lid of the packing box includes a part that can be torn along a tear inducing line extending from the flap opposing edge of the top face lid to the front end edge of the top face lid.

Abstract: A machine tool including a base frame, a workpiece table, a machining unit, and a connection portion is disclosed. The base frame has a machining area. The base frame includes two left and right side frames and a connection frame connecting the two side frames. The workpiece table is arranged on the base frame in the machining area. The machining unit is arranged on an upper portion of the base frame and includes a spindle device. A connection portion connects the machining unit and the base frame in a detachable manner.

Abstract: Provided is a horizontal machine tool with a base frame including a base part and a saddle supporting part vertically standing on the base part; an X-axis saddle mounted on the back face of the saddle supporting part and capable of sliding in the left-right direction via an X-axis translation mechanism; a Y-axis saddle mounted on the X-axis saddle and capable of sliding in the up-down direction via a Y-axis translation mechanism; and a spindle device mounted on the Y-axis saddle and capable of sliding in the front-rear direction via a Z-axis translation mechanism. The horizontal machine tool is adapted such that a workpiece supporting member is installed on the base part in front of the saddle supporting part. This configuration can reduce the size and weight of the entire construction.

Abstract: A pneumatically static balancer for a machine tool counterbalances or lightens a gravitational load generated by an own weight of a vertically moving driven member. The pneumatically static balancer includes a pneumatic cylinder supporting the driven member and allowed to move vertically, a pneumatically static bearing having a piston inserted into the pneumatic cylinder, the pneumatic static bearing being formed by feeding compressed air, which is in an interior of the pneumatic cylinder, into a small clearance formed between the pneumatic cylinder and the piston, a cylinder rod connected to an upper end of the piston and a saddle supporting a leading end portion of the cylinder rod.

Abstract: A main spindle apparatus has a main spindle having a through hole, a main spindle head rotatably supporting the main spindle therein, a tool holder clamp unit including an unit main body having a tool mounting hole to which a tool holder is mounted, a clamp mechanism for clamping the tool holder and a bias mechanism for biasing the clamp mechanism in a clamping state and a clamp release mechanism provided on the main spindle head side and releasing the clamping state of the clamp mechanism by operating the bias mechanism, wherein the tool holder clamp unit is mounted on the though hole of the main spindle so that the tool holder clamp unit is detachable from front side of the main spindle.

Abstract: In order to satisfy the requirements for satisfactory levels of melting•burn-off characteristics in response to heat application, high temperature burn-off characteristics and ease of residual ash removal that a resin model should assure as an alternative to a wax model, the burn-off resin model according to the present invention, which can be used in the lost wax process, is manufactured by forming a liquid resin compound containing 1 to 30 wt. % of a plasticizer (D) and 1 to 20 wt. % of a wax component (E) blended into a double fluid reactive setting liquid urethane resin (C) constituted of a multifunctional polyol component (A) and a multifunctional polyisocyanate component (B) and then by setting the liquid resin compound within a working life of 5 minutes or less.

Abstract: A power system for a vehicle having a power source for supplying an electric energy to a plurality of electric load groups with mutually different voltages, comprises a plurality of load elements forming each electric load group, and a plurality of output means for taking out the electric energy for each preset voltage as an intermediate voltage from the power source, the plurality of output means being located in the power source, wherein the plurality of load elements in either load group are divided into some blocks and connected to each output means so as to allow an electrical power simultaneously consumed by each divided block to become substantially equal. Additionally, one of some blocks divided in the load group is set to have more load than the other blocks. The power system for the vehicle improves the load balancing of the battery without using a special battery monitoring device nor a DC/DC converter while taking out the desired intermediate voltage from the high voltage battery.
