Title: Method for changing resin in injection molding machine
Inventor: KASAI MASAYOSHI
IPC: B29C45/00
Filed: 1982-03-15
Abstract: PURPOSE:To save resources, energy and manpower, by applying a forced back pressure to a screw, with a nozzle being compressed to a resin changing block, when the resin is changed, repeating the screw rotation and injection, thereby completing the resin change in a short time. CONSTITUTION:The resin changing block 1, whose temperature is adjusted, has a pressure yielding mechanism. The resin is flowed from the nozzle 21 through the resin changing block 1. The nozzle 21 is compressed to the resin changing block 1 by a pull back cylinder 22. Under this state, plasticization and injection are repeated, and the stable high pressure is yielded. A gap (d) is suitably set by a pressure adjusting bolt 12. When the screw is rotated with the screw back pressure being applied, the back pressure at the gap (d) is large, and the screw back pressure effectively acts on a surface (e) and an inner wall surface (f). Then slipped shearing stress is applied under the high pressure, and the resin change is accelerated. A heater 10 and a thermocouple 11 are provided in the resin changing block 1 and the temperature is adjusted.

Abstract: PROBLEM TO BE SOLVED: To prevent a maloperation by arranging an interlock mechanism, by which a cut off clutch can be operated so as to be connected while a connected clutch cannot be operated so as to be cut off when a winch drum is not braked. SOLUTION: When a solenoid 22 is demagnetized without operating any brake pedal, an interlock plate 21 is rotated by means of a return spring 28 until a stopper 26 collides against a stopper receiver 27, and the lower face of a pin 17 penetrating a clutch lever 10 is engaged with the upper face of the interlock plate 21, so that the clutch lever 10 is prevented from being operated from the clutch connection position to the clutch cutoff position. On the other hand, when the clutch lever 10 switched to the free-fall position is rotated counterclockwise around a pivot shaft 11 against the return spring 28 in the interlock plate 21, the clutch lever 10 can be switched from the free-fall position to the operation position. In this way, a maloperation of a winch is prevented, and operability can be improved.

IPC: B60K6/445
Filed: 1999-02-19
Abstract: PROBLEM TO BE SOLVED: To provide a starting control system that appropriately executes a judgment of perfect ignition in the engine at starting. SOLUTION: An engine, motor MG1, motor MG2, and axle are connected via planetary gears to constitute a hybrid vehicle. The engine is cranked to start by means of the torque of the motor MG1. If the engine speed is lower than the igniting speed Netag, the torque of the motor MG1 is changed according to a predetermined pattern. After the igniting speed is achieved and the engine operation is started, the torque of MG1 is set by PI control so that the engine speed becomes a predetermined target speed N1*. The target speed N1* is set lower than an engine idling speed Ne*. When the engine starts self-sustaining operation at the idling speed Ne*, the torque of the motor MG1 changes into the negative region. With this change of torque, reliable judgement of perfect ignition can be executed.
