Title: Control apparatus for automatic transmission
Inventor: AMANO MATSUO
IPC: F02P5/15
Filed: 1991-04-22
Abstract: PURPOSE:To provide a control apparatus for an automated stepped speed change gear wherein always effective torque down control in the course of speed change is possible and sufficient shock mitigation at the time of changing-over the speed is possible. CONSTITUTION:By operating shift solenoid valves 16A, 16B of a speed change valve 15, the shift position of a speed change gear 11 is determined. During operation of a speed change mechanism, feedback control is inhibited and ignition timing theta, fuel quantity T and a by-pass valve 21 are controlled, by a control apparatus, to decrease the output torque of the engine. This eliminates the factors of obstructing the decreasing of the engine output torque to obtain a torque down in proportion to the magnitude of the load. This enables minute adjustment of the torque to enable simultaneously achieving both the decrease in the speed change impact and the durability of the automatic transmission.

Title: Dry-distillation incinerator
Inventor: TADA KENICHI
IPC: C10B53/07
Filed: 1978-09-21
Abstract: PURPOSE:To efficiently operate a dry-distillation incinerator, by providing a dry- distillation incineration vessel made of a conveyable retort-shaped container to dispense with scrape-out work or throw-in work. CONSTITUTION:The retort-shaped container 1 is provided in a high-temperature gas bath vessel 2. The open mouth of the vessel 2 is closed with a flange 12. Combustion is caused in a high-temperature gas generation furnace 24 to supply high- temperature gas into the high-temperature gas bath vessel 2. The high-temperature gas is not directly released to the atmosphere. Heat is efficiently transferred from the gas to a waste matter in the retort-shaped container 1 while the gas rises in the bath vessel 2. The waste matter is thus dry-distilled for incineration. After the dry-distillation incineration is finished, the container 1 holding residues is lifted out of the bath vessel 2 by a conveyor such as a crane and conveyed to a cooling process. After the residues are cooled, they are picked out of the container 1.

IPC: H02M3/28
Filed: 1994-05-31
Abstract: PURPOSE:To obtain a highly efficient small-thin DC power supply for driving an electronic apparatus by reducing the size of a transformer and enhancing the conversion efficiency. CONSTITUTION:The DC power supply comprises a transformer 2 having the primary connected in series with a switching element 1 for switching the input DC current and the secondary connected with a smoothing capacitor 4 through a rectifying element 3 wherein the plus side of a primary coil 2a is connected with the minus side of a secondary coil 2b such that the input DC voltage on the primary is added to a DC voltage generated on the secondary of the transformer 2.
