Title: Magnetic recording/reproducing device
Inventor: WAKUI YOSHIAKI
IPC: G11B15/44
Filed: 1987-03-16
Abstract: PURPOSE:To keep the number of revolutions of a motor constant at the time of recording/reproducing and at the time of fast forwarding/rewinding by arranging a 1st rotary body between a driving source and capstan, driving it by its rotation via two belts and driving a reel base by selectively driving two idlers as well. CONSTITUTION:The rotary force of a capstan motor 52 is transmitted to a center pulley 54 and the large intermediate pulley 55 becoming a fly wheel via a belt 53 and the intermediate large pulley 55 drives the capstan fly wheel 58 having a capstan shaft 73 by its rotation via a belt 57 from a small intermediate pulley 56. A center gear 59 capable of meshing with FF/REW gear 60 is integrally provided coaxially with the rotary shaft 54a of the center pulley 54. The number of revolutions of FF/REW mode and PLAY/REC mode can be controlled by making the number of revolutions of a capstan motor 52 constant by changing over the meshing of the center gear 59 and FF/REW gear 60, and the structure of a motor driving circuit, etc., is simplified.

Title: Aeration equipment
Inventor: AKITANI HIROSHI
IPC: C02F3/12
Filed: 1979-05-18
Abstract: PURPOSE: To effect stable water treatment by reducing the phenomenon called reverse mixing which involves a flow of mixed liquid downstream side to the upstream side through rectifying walls in an aeration tank.  
     CONSTITUTION: The degree of opening ratio made on rectifying plates 14aW14d arranged in flow direction of mixed liquid in an aeration tank 1 is made sucessively larger toward downstream. This reduces the amount of reverse mixing in the area where organic substance concentration is high. If much reverse mixing occurs upstream, this causes sewage underwent insufficient aeration treatment to be flowed down by the action of reverse mixing and results in insufficient stay time. If reverse mixing occurs downstream, this practically causes no trouble because some degree of treatment has beem already conducted.

Title: Evaporation fuel processor
Inventor: OSANAI AKINORI
IPC: F02D43/00
Filed: 1994-03-30
Abstract: PURPOSE:To provide an evaporation fuel processor which can make the change of an air-fuel ratio small at the change control time of a purge rate. CONSTITUTION:The fuel that has evaporated in a fuel tank 13 is accumulated in a canister 14 through vapor piping 133. When a purge valve 142 is opened during operation, the fuel accumulated in the canister 14 is led to an air intake pipe 11 by means of the negative pressure of the air intake pipe 11, and is used as fuel. When the purge valve 142 is opened rapidly at the time of purge start, an air-fuel ratio is changed largely, so this processor possesses a means that makes a purge rate large step by step and at the same time learns the density of evaporation fuel to be purged, and when the degree of learning is small, it is considered that the fear of giving disturbance to the air-fuel ratio is high, and so the change rate of the purge rate is made small.
