Title: Elastic roller
Inventor: KON SHUJI
IPC: C08J7/00
Filed: 1992-01-29
Abstract: PURPOSE:To produce a roller which has excellent durability and comprises a fluororesin tube and an elastic material tenaciously bonded thereto. CONSTITUTION:The inner wall of a fluororesin tube 5 is etched by dipping it in an etchant which is a solution of Na in liquid ammonia, thereby regulating the inner wall to have a contact angle of 25-35 deg.. A primer is applied on the surface, and a roller 4 comprising a core metal 2 and an elastic material 3 formed thereon is inserted into the tube 5 to thereby unite the roller 4 with the tube 5. Due to the contact angle of 25-35 deg. obtained by the etching, a functional group chemically bonds to the primer to attain tenacious adhesion. The title roller is obtained at a low cost.

Title: Rotary hammering tool
Inventor: HARADA SHUICHI
IPC: B25B21/02
Filed: 1999-01-22
Abstract: PROBLEM TO BE SOLVED: To operate only the essential hammering motion and to control the torque with high accuracy by providing an insensitive time shorter than a hammering period so as not to receive the input from a hammering detecting means during this insensitive period. SOLUTION: When an operator pulls a main switch 3, a control is started for supplying a power source to a microcomputer 6. The rotating direction is judged first on the basis of the output from a forward and backward rotation judging means 9, and a set value of a setting means 4 is read in the case of forward rotation. Then a motor 2 is started by turning a switching means 7 on. When the first hammering is detected by a signal of a hammering detecting means 5, a timer for measuring the insensitive time is started. When a hammering times do not reach a set value, the detection of the hammering signal is started again after the set insensitive period passes. When the hammering times reaches the set value, the motor 2 is cut from a battery 1 of the power source by the switching means 7 to stop the motor 2.

Hydrogen sulfide and carbonyl sulfide contained in the coal gasification gas is turned into sulfur dioxide by the gas turbine combustor 310. The gas generated by the gas turbine combustor 310 is used as working medium gas 15 for a gas turbine 330 which is driven to obtain electric power generated in a ganerator 340. The gas turbine 330 exhausts gas turbine exhaust gas 16 containing the sulfur dioxide and moisture. The gas turbine exhaust gas 16 is separated and recovered by a water recovery/desulfurization device 430. Accordingly, high efficiency is implemented without lowering gasified gas to ordinary temperature.

     CONSTITUTION: The fuel introduced from a fuel pipe 7 is burnt in a burner 8 by the help of air supplied through an air pipe 6 and the combustion gas G of high- temperature flows through a gas passage 9 into a fluidized bed 2 from a small orifice provided in a flow-regulating plate 3, giving a fluidizing force to the bed 2. To the gas passage 9 near the place where the combustion gas G reaches the flow- regulating plate 3 is connected an air pipe 6' for cooling branched from the air pipe 6 so as to mix the combustion gas G with the air for cooling. By this, the temperature of the combustion gas G at the inlet of the flow-regulating plate is regulated to be below the low-melting point of the EP ash, i.e. the temperature between 500°C and 550°C approximately, thereby the temperature in the lower part of the fluidized bed, especially at the place near the flow-regulating plate 3, being held below the low-melting point. In this way, the sticking of the melted EP ash to the flow-regulating plate 3 is prevented.
