Title: Automatic transmission controller for vehicle
Inventor: HIRANO MASAMITSU
IPC: F16H61/16
Filed: 1996-12-06
Abstract: PROBLEM TO BE SOLVED: To provide such an automatic transmission controller for a vehicle as being capable of prohibiting shift-up from the second variable speed gear to the third variable speed gear when driving wheels are slipped and accurately cancelling the prohibiting of shift-up. SOLUTION: When a throttle opening TH is increased by stepping an accel pedal when a vehicle is started on an ice-covered road with a low road surface friction coefficient, a body speed V detected in accordance with the rotating number of the output shaft of an automatic transmission is abruptly increased with the occurrence of slip but an actual body speed V(F) is gently increased because grip between a driving wheel and a road surface is lost. Body acceleration which is normally generated on a flat road is previously stored, an estimated body speed VYS is calculated from the body acceleration and a time passed after the slip occurs and the grip between the driving wheel and the road surface is judged to be recovered when the detected body speed V is below the estimated body speed VYS, so that the prohibition of shift-up is cancelled.

Title: High precision molding die and molded product
Inventor: TAKESHITA MASAMICHI
IPC: B29C45/76
Filed: 1990-11-30
Abstract: PURPOSE:To realize the mechanism reducing the deformation of a mold and the mold structure, in which deformation is difficult to be generated, by preventing the deformation of a cavity by resin pressure injected or the lowering of the parallelism of a stationary mold and a movable mold forming the cavity even when the cavity is deformed. CONSTITUTION:The quantity of deformation is detected by a deformation detecting sensor 13 installed to a movable mold 6, and the signal is transmitted over a control section 11. The control section 11 compares the quantity of deformation with a previously input deformation-quantity target value and decides it, and controls the injection speed and/or injection pressure of a molding-machine injection section 12 so that the quantity of deformation reaches the target value or less. When the control section 11 controls a hydraulic cylinder 15 in the rear section of a support 14 in response to the quantity of deformation detected by the deformation detecting sensor 13, the hydraulic cylinder 15 varies hydraulic power in response to a controlled variable. The hydraulic cylinder 15 applies pressure to the support 14 from a rear section, and the support 14 is finely forwarded or finely retreated against resin filling pressure. The deformation of the movable mold 6 is corrected through a back plate 19 and a thermally insulating board 18.
