Title: Electroconductive magnetic toner
Inventor: KISHI HIROYOSHI
IPC: G03G9/083
Filed: 1987-06-05
Abstract: PURPOSE:To facilitate prepn. of a magnetic toner having minute particle size and to make magnetic characteristics of the toner uniform by depositing magnetic iron oxide particles derived from magnetotactic bacteria to the toner particles. CONSTITUTION:Magnetic iron oxide powder derived from magnetotactic bacteria is deposited to toner particles. Since the bacteria contain plural numbers (10 - several tens) magnetic bodies in the cell, the magnetic bodies are used as magnetic particles after separating the magnetic bodies consisting of iron oxide from the bacteria. The magnetic bodies have superior characteristics in its extremely fine and uniform particle size and high purity. In an electroconductive magnetic toner contg. magnetic iron powder derived from magnetotactic bacteria deposited as magnetic particles contributing also as an electroconductive material to the periphery of the toner particles, the particle size of the toner can be made minute by balancing the particle size of the toner to the particle size of the magnetic bodies. Thus, an electroconductive magnetic toner capable of providing a picture image of high quality is obtd. because of high purity, uniform particle size and quality of the magnetic bodies used therein.

IPC: F01L9/02
Filed: 1985-06-27
Abstract: PURPOSE:To reduce the output loss due to the valve driving by operating the exhaust valve of a 2-cycle engine by a hydraulic pressure in the initial period of opening and carrying out opening operation by utilizing the scavenged-gas pressure afterwards. CONSTITUTION:An exhaust valve 5 installed onto a 2-cycle engine 12 is equipped with a hydraulic cylinder 4 at the upper edge and a pneumatic cylinder 7 in the intermediate part. In the initial period in the opening of said exhaust valve, a solenoid valve 1 is opened to allow the pressurized oil to act onto a piston 5a, and the valve is opened by the high-pressure force against the gas in the cylinder under high pressure. Then, a solenoid valve 9 is opened to introduce the scavenged-gas pressure in a crank chamber into a piston 8 through a hole 10, chamber 15, and a pipe 14, and the opening operation is performed by said pressure. Though the exhaust valve needs a large force in the initial period of opening, only the force for a valve closing spring 6 is necessary afterwards, and a large hydraulic pressure is not needed, and opening operation is performed only by the scavenged-gas pressure only.
