Inventor: ARAI MINORU
IPC: F02D21/08
Filed: 1985-04-13
Abstract: PURPOSE:To efficiently perform reburning of soot contents in exhaust gas by mounting both an exhaust heat controller which increases exhaust heat when an engine runs within a low and middle load range and a heater controller which heats the soot contents in exhaust gas if exhaust heat cannot be increased sufficiently. CONSTITUTION:A throttle valve 4 and an EGR valve 5 which are incorporated in the intake system of a Diesel engine 1 are opened and closed under the control of a vacuum control valve 6. Said valve 6 are suitably controlled by a controller 9 on the basis of the signals from an air flow sensor 3, an engine load sensor 7 and an engine revolution sensor 8. A catalyst-containing tap 11 including a supplementarily reburning electric heater 10 in the upper stream side thereof, is incorporated in the exhaust system of said engine 1. Said heater 10 is most suitably controlled by the controller 9 on the basis of the signals from said sensors 7 and 8 and an exhaust temperature sensor 12.

Abstract: PURPOSE:To provide a high performance engine, which is constituted to combine high thermal efficiency with quietness and exhaust gas low environmental pollution, and a combustion system therefor, in the fundamental combustion arts of a direct injection compression firing system internal combustion engine. CONSTITUTION:A jet flow-form fuel group 5 is brought into collision with a fuel collision part 2 in a piston cavity 1, and a reaction area is rapidly formed in a compression atmosphere combustion chamber. By feeding a subsequent fuel group in an initial reaction area A, orderly development of a fuel group owing to collision diffusion is effected by a reaction internal part. By orderly fuel development at the reaction internal part, feed fuel is activated by utilizing heat exchange and latent heat operation occasioned by vaporization and gasification of a diffusion fuel group. Simultaneously, control of the temperature of a reaction area is executed. Further, the reaction area is enlarged and developed by a means to feed fuel to the reaction internal part, and by establishing a condition to positive mix with air in a development progressing area, diffusion combustion based on a fuel injection rule is caused to occur to temperature control atmosphere.

Title: Record player
Inventor: OBATA SHUICHI
IPC: G11B3/085
Filed: 1986-04-04
Abstract: PURPOSE:To eliminate such an action that a tone arm turns with its record stylus dropping by stopping the turn of the tone arm when no ascent of the tone arm is detected by a lift-up detecting means after a fixed period has passed since an ascent command was given to the tone arm. CONSTITUTION:The ascent command is given to a lift-up device, and detected by the lift-up detecting means. If the tone arm does not lift-up during a fixed period, this is considered to be a trouble to stop a turntable. Then the effect is reported and the arm is not moved. Said fixed period must be longer than the time necessary for lifting up the arm. Thus the accident due to the trouble of the turntable can be previously prevented, and the trouble of the lift-up device can be reported by stopping the rotation of the turntable.

Title: Electromagnetic drive shutter
Inventor: SUGIURA HIROTSUGU
IPC: G03B9/36
Filed: 1979-06-22
Abstract: PURPOSE: To make possible the high-speed driving of the electromagnetic drive shutter by small electric power by mounting the rotor of an electromagnetic drive source with a deviation of center from its axis and disposing the acting point of a rotating power transmission mechanism to shutter blades on the short diameter side of the rotor.  
     CONSTITUTION: Rotating motion of a rotor 1 is transmitted by way of a revolving shaft 5 to shutter blades to let the shutter blades travel. Here, the rotor 1 is mounted to the shaft 5 with a deviation of its center therefrom, and if the acting point of a rotating force transmission mechanism to the shutter blads is beforehand disposed on the short diameter side (lightweight side) of the rotor 1 and is let to make rotating motion within a fixed angle, the loads on the long diameter side and short diameter side of the rotor may be balanced. Hence, this results in that the electromagnetic drive source operates most efficiently and requires less driving electric power. In this way, the high-speed driving of the electromagnetic drive shutter by small electric power is made possible.
