Title: Image forming method
Inventor: YAMADA HIROYUKI
IPC: G03G9/08
Filed: 1988-01-08
Abstract: PURPOSE:To improve the cleaning property by using a toner containing a binding resin grain and an organic fine grain whose diameter is smaller than that of said grain. CONSTITUTION:A toner for constituting a developer is allowed to contain a binding resin grain consisting of a stylene compound resin, etc., and an organic fine grain consisting of a vinyl compound polymer, etc., whose diameter is smaller than that of said grain. As for the mean diameter of a primary grain of the organic fine grain, 0.01-5mum is desirable, and when the mean diameter is excessive, the developing density of the toner is apt to drop due to the drop of fluidity of the toner. On the other hand, when the mean diameter is too small, a sufficient cleaning property cannot be obtained. As for such a toner, physical sticking force to a latent image carrying body 10 is weak, no damage is attended in the carrying body 10 and a cleaning blade 52, and a residual toner can be brought to cleaning satisfactorily.

Title: Spilled oil recovering device
Inventor: SHIMIZU AKIRA
IPC: C02F1/40
Filed: 1978-01-10
Abstract: PURPOSE: To facilitate an oil-recovering device to recover oil spilled into the sea surface, etc. by jetting hot water (or heated water) onto the oil floating on the surface.  
     CONSTITUTION: The oil recovering device is a device provided with forward-opening side plates 11 and a suction inlet 12, which is designed to condense oil layer, and is composed of a jetting device 14, which is located in front of the side plates 11 for moving backward of oil layer stagnating between the side plates 11, and also of a heater 18, which is to heat the fluid to be jetted out from the jetting device 14. In the above mechanism, as viscosity of oil is lowered by thus heated and jetted out from the jetting device 14, the oil is made to form a bridge so that such an inconvenience as slowdown of flow to the suction inlet 12 can be prevented. And at the same time, sine the recovered oil's temperature is raised, segregation between oil and water contents in a segregating tank can be accelerated. And therefore, this device is designed capable of serving not only the primary purpose but also the secondary purpose at the same time.

Abstract: PURPOSE:To easily and surely control normal operation and power down operation of a multicylinder type rotary compressor by opening/closing a plurality of release holes by a valve unit so as to switch a plurality of cylinders to a communicating common condition or to a cutoff independent condition. CONSTITUTION:At the time of normal operation, an opening/closing valve 27 is opened. Then, delivery gas in a closed vessel 1 is introduced to a valve hole 20 through a delivery pressure passage 24 to generate a delivery pressure in a lower surface of a valve unit 21. Suction gas is introduced from a suction passage 25 to provide a suction pressure in an upper surface of the valve unit 21. Now when resilient force of a compression spring 22 is decreased smaller than the delivery pressure, the valve unit 21 is lifted above the valve hole. As a result, each release hole 31, 32 is blocked by a peripheral surface of the valve unit 21. Accordingly, mutually independent compressing action is performed in each cylinder 6, 7. On the other hand, at the time of power down operation, the opening/closing valve 27 is closed. Then, high pressure gas is released from the one to the other of each cylinder 6, 7 to perform power down of compression.

Filed: 1988-01-08
Abstract: PURPOSE:To shorten operation start preparation time by introducing a combustion exhaust gas into a catalyst layer in a reformer to remove oxygen to produce inert gas, and replacing a fuel gas left in a system with the inert gas when the system is suspended. CONSTITUTION:When a system is suspended, air supply to a fuel cell main body 15 is stopped and a raw material pump 6 is also stopped. A raw material left in a carburator 10 is reformed with a reformer 11, and supplied to the cell main body 15, then burned with a burner 8 of a fuel reforming unit 29 as off-gas. At the same time, a closing valve 14 in a combustion gas introduction line 20 is opened and an exhaust gas is introduced into the reformer 11. Although the oxygen concentration in the exhaust gas is lower than in air, oxygen in the exhaust gas is removed by contact reaction in the reformer to form inert gas. This inert gas is supplied to the cell main body 15 from a fuel electrode inlet 16. Since the exhaust gas which comes in contact with a catalyst in the reformer has low oxygen concentration, when cell operation restarts, the rereduction of the catalyst is unnecessary.
