Abstract: PURPOSE:To make it possible to shorten the time of gear shift of an automatic speed change gear having no synchronizing mechanism, by abruptly decreasing the rotational speed of an engine with the use of an exhaust brake during high load operation in accordance with the detected torque value of the output side. CONSTITUTION:In an automatic speed change gear, a shift valve 17 actuates selector valves 19 through 22 through a shift shaft 18 so that sleeves 13a through 16a in drag clutches 13 through 16 are shifted to selectively engage one of gears 3b through 9b, thereby, the rotation of a counter shaft 10 is transmitted to a main gear shaft 11 through a predetermined gear ratio. In this arrangement a load torque is calculated from the phase difference between pick-ups 27, 28 for measuring the rotational speed of the main shaft 11. Further, in order to initiate a gear shift, at first the speed change gear is set at its neutral position, and then those of the select valves 19 through 22 at a desired position are driven to operate an exhaust brake during high load operation so that the rotational speed of the engine is lowered to allow a gear shift.

Title: Plate brick for sliding nozzle
Inventor: OOHORA YORIKO
IPC: B22D11/10
Filed: 1994-05-16
Abstract: PURPOSE:To definitely control the flow rate of the molten steel by the stroke of plates by making a nozzle hole of the plate for a sliding nozzle square. CONSTITUTION:Sliding nozzles of all plates for sliding nozzle are circular in shape, and it is inconvenient to control the flow rate when the flow rate is controlled by the stroke. The flow rate of the molten steel becomes definite by the stroke of plates 1, 2 by making the nozzle hole 3 square in place of the conventional circular nozzle hole. That means, when the nozzle hole 3 is made square, the easy result such as ab/2 can be satisfied when the flow rate is made half of that in the fully closed condition of the nozzle hole 3. The relationship between the stroke and the flow rate is linear, and the flow rate of the molten steel becomes definite by the stroke of the plates 1, 2.

Accordingly, as the adhesive area of the rear 2b with the sealing resin material (a package main body 5) is sufficiently increased, the interfacial bonding force between the rear and the package main body is strengthed and a stress of generation at the time of a temperature rise at the time of packaging is dispersed by a dimpled configuration on the island part rear 2b. Thereby, even if a thermal stress is applied to the whole device at the time of packaging, a peeling phenomenon on the sides of the rear 2b and the sealing resin material is inhibited and the generation of crack in the main body 5 is prevented.
