A bearing installation for a Floppy Disk Driver motor which is simple in structure and high in accuracy of a rotating action of a rotary shaft, thus hardly impairing the read and write characteristics of a Floppy Disk Driver device. A bearing installation for a Floppy Disk Driver motor includes a protective cap mounted to one side of the motor; a first pivot bearing arranged for free and axial movements on a rotary shaft of the motor relative to the protective cap; a thrust spring urging axially the first pivot bearing on the rotary shaft of the motor; the rotary shaft fixedly mounted on a rotor of the motor, and supported pivotally at one end by the first pivot bearing and at the other end by a second pivot bearing fixedly mounted on a platform on which the motor is installed; a lead screw joined to an outwardly extending portion of the rotary shaft from the motor; and a positioning bushing arranged through which the rotary shaft fixed to the motor extends without direct contact with and closely fitted into a positioning hole provided in a plate to which the motor is secured.

摘要:
A race game of the type wherein a housing has a surface with two channels located therein with an endless belt moving in each of the channels is improved by attaching to one of the endless belts a first upstanding member and attaching to the second endless belt at least one second upstanding member. Portions of the first and second upstanding members project upwardly from the surface. A motor is located in the housing and connects to the first and second endless belts. The motor drives the endless belts which in turn moves the first and second members in continuous pathway over the surface. At one point on the surface the continuous pathways converge toward each other and at another point they diverge. The first and second members are each capable of engaging with a portion of a small wheeled race vehicle and pulling these vehicles across the surface. Where the pathways converge one of the small vehicles is capable of striking and dislodging the other of the small vehicles from the member to which it is attached. Included as part of the game is a speed regulating system wherein the speed of one of the endless belts can be regulated such that the vehicle attached to it can go faster than, at the same speed as or slower than the other vehicle. This allows the operator of the game to control the vehicle attached to the regulated endless belt to avoid dislocation of the controlled vehicle off of its driving member by preventing interaction of the two vehicles.

A toy trackway featuring a platform having an upper level and a lower level, the upper level provided with a trackway terminating at each end in a locking member, the lower level provided with two trackways each terminating in a locking member, and two flexible trackways, each terminating in locking members for engagement with the locking members of the trackways of the upper and lower levels of the platform, thus permitting one of the locking members of each of the flexible trackways to be attached to the locking members of the trackway of the upper level and the other of the locking members of each of the flexible trackways to be attached to the locking members of the trackways of the lower level either on the same side of the platform or on opposite sides of the platform.
摘要:
In a combustion chamber, auxiliary combustion is effected by using carbon monoxide and/or hydrogen immediately after each charge of the main fuel has been burnt up therein. This method of combustion enables the nitrogen oxides resulting from the combustion of the main fuel to be reduced and brought to extinction by the auxiliary combustion, with the result that the nitrogen oxide content of the exhaust gas from the said combustion chamber is depressed.
