Title: Tooth shape of sprocket
Inventor: SATOU OSAMU
IPC: F16H55/30
Filed: 1982-05-24
Abstract: PURPOSE:To effectively reduce the creation of noises at a working time, by enlarging radius R of the circular arc of the tooth base of a sprocket, compared with the radius of a roller chain or the radius (r) of the bush of a bush chain. CONSTITUTION:A drawing shows a condition in which a roller 7b in a timing chain 7 just set in a space between adjoining teeth of a sprocket 4, and the centers of the rollers 7a and 7b are positioned on a pitch circle P. Where the sprocket 4 turns by theta=pi/Z from said condition, the roller 7b is smoothly displaced from the initial entrance level H1 to a level H2 along the circular arc 4a of a tooth base. If, subsequently, the sprocket 4 turns by theta=pi/Z, the roller 7b smoothly moves to the maximum engaging point 02 from a point 01 along the circular arc 4a, and this eliminates the possibility of hammering noises created between the roller 7b and the sprocket 4.

Abstract: PURPOSE:To eliminate the need for countermeasures against high voltage of each element and make possible resetting of the device with a simple constitution by providing a timer circuit which automatically opens when a power source switch is neglected to be turned off to the primary side of the device. CONSTITUTION:When a power source switch 2 is turned ON, a DC-DC converter circuit 3 operates to charge a main discharging capacitor 8. At the same time, the voltage of the base winding 5a of an oscillation transformer 5 is rectified by a rectifier part 15 and charges the charging capacitor 22 of a timer circuit 18. Even when the switch 2 is neglected to be turned OFF, a switching element 23 is conducted to let this capacitor discharge and cause an electromagnet 24 to be energized, by which the switch 2 is automatically reset to the OFF position upon reaching of the charging voltage of the capacitor 22 at the specified value after lapse of a fixed time. When the capacitor 8 is charged and a shutter button is pushed prior to discharging of the capacitor 22, synchronizing contacts 12 close and a flash discharge tube 14 emits light, at the same instant of which a switch 25 closes cooperatively to discharge the charged charges of the capacitor 22, thereby returning to the initial state.

Abstract: PURPOSE:To damp large amplitude oscillations in all direction, by constituting a chamber wall of a fluid chamber connected to a vibrating body with a rubber elastic body being small in a static dynamic ratio, while interposing another rubber elastic body being large in the static dynamic ratio between the chamber wall and the vibrating body. CONSTITUTION:A rubber elastic body 7 being large in a static dynamic ratio is set up inside a cylinder of an upper plate 8, while another rubber elastic body 1 being small in the static dynamic ratio is used for a chamber wall of a first fluid chamber A. Therefore, the rubber elastic body 1 is not almost deformed against vibrations in both directions as it is in a compressive direction and, what is more, damping action for vibrations by a sealing fluid is in no case produced. On the other hand, a bolt 9 relatively moves in both directions to the upper plate 8 supported by the rubber elastic body 1 according to the vibrating input, whereby the rubber elastic body 7 large in the static dyamic ratio is deformed in a shearing direction, producing large damping resistance there, thus vibrations in both directions are speedily damped.
