Title: Controller for automatic transmission
Inventor: NIIDE KAZUO
IPC: F16H61/10
Filed: 1987-06-12
Abstract: PURPOSE:To effectively reduce shock caused by shifting operation by extending the time for accelerating the engaging speed of the servo-mechanism at a low temperature of a speed change gear mechanism more than that at a normal temperature thereof. CONSTITUTION:Upon shift-up for shifting power transmission lines to a low speed stage to a high speed stage in a speed change gear mechanism 2, in a servo-mechanism 24 engaged, the engaging speed is controlled by an engaging speed control means 70. The engaging speed is accelerated during the initial and middle stages of engaging and thereafter decelerated. At a low temperature of the mechanism 2, the viscosity of oil with respect to the mechanism 24 is high so that a delay occurs in its supply, but a fixed time for accelerating the engaging speed is changed to be long by a low temperature time controller 71. Hence, the engaging speed of the mechanism 24 is accelerated at the initial and middle stages of engaging so that it is similar to the case at the normal temperature. Then, the delay of oil supply is compensated, while the engaging speed is decelerated at the final stage of engaging. As a result, a smooth engaging of the mechanism is ensured in a short time and therefore shock caused by shifting is effectively reduced.

Title: Vacuum drawing injection molding device
Inventor: SHIBUI YUICHI
IPC: B29C45/26
Filed: 1987-06-12
Abstract: PURPOSE:To prevent defective molding such as a void from occurring by preventing staying of air or expandable gas to be generated within a mold by absorbing the same immediately, by a method wherein a seal member is provided on the surface of a bottom force at a part of the circumference of a vacuum drawing hole and a porous body is fixed to a position facing on the seal member of the inside of an insert member further. CONSTITUTION:Air within a cavity 5 is sucked through a vacuum drawing hole 8 provided on the top of a bottom force 3 and mold clamping is performed by performing mold register of a top force 1 and the bottom force 3 through cores 6, 7 while vacuum drawing is started. In this instance, as a seal member 9 and skin member 4 provided on the bottom force 3 are stuck close to each other, a urethane solution 13 which has flowed out into a gap between the bottom force 3 and skin member 4 through the vacuum drawing hole 8 is prevented from adhering to the surface of a product. When the air and expandable gas which are staying within the urethane solution 13 are sucked through the vacuum drawing hole 8 after the top and bottom forces 1, 3 have been made into a sealed state, a porous body 10 stuck to the inside of the insert member 2 abuts against a small hole or slit 4a formed on the skin member 4 by communicating with the vacuum drawing hole 8. Therefore, the air and expandable gas within the urethane solution 13 are sucked through the vacuum drawing hole 8.

Title: Pressure leak measuring method
Inventor: HORIKAWA HIROSHI
IPC: G01M15/00
Filed: 1995-06-14
Abstract: PURPOSE: To shorten the measuring time by starting the measurement of pressure leakage at a moment of time when the variation of pressure difference per unit time becomes constant when a pressurized gas is introduced between an object and an independent space of it and the pressure difference between them is measured after a predetermined time. CONSTITUTION: As a solenoid valve is switched to interrupt an object to be measured from a master, a pressure difference is generated while being accompanied with fluctuation. Actual inner pressure of the object fluctuates due to adiabatic compression, etc., within a ΔT2 and the sum of a pressure difference ΔP due to pressure leakage and a pressure difference ΦP0 due to pressure fluctuation is detected as a pressure difference within the range ΔT2. After the end point MP4 of the range ΔT2, only the pressure difference ΔP due to pressure leakage from the object can be detected as a pressure difference. When the point MP4 is determined accurately and the measurement is started at that moment of time, the measurement can be carried out in a shortest time.  More specifically, the point MP4 is determined by differentiating the unit time moving average of measurement of pressure difference twice.
