Filed: 1999-02-04
Abstract: PROBLEM TO BE SOLVED: To provide an apparatus strong in mechanical strength by forming a drive piece of a thermosetting composite material formed by using a thermosetting resin as a base material and by mixing powder of a filler of ceramics, carbon or metal in the base material. SOLUTION: This electromagnetic relay 1 uses a thermosetting composite resin for a drive piece 13, can thereby avoid the fusion or deformation of the drive piece 13 due to heat from the outside and the breakage of the drive piece 13 due to shock from the outside, and does not wear down peripheral components with the drive piece 13. The thermosetting composite resin uses a phenol resin as a thermosetting resin for its base material, and powder of alumina is mixed in the phenol resin as a filler. The filler is an inert substance, for instance, ceramics, glass, metal or carbon that is added for improving the properties of plastics such as strength and durability. By using the thermosetting composite resin for the drive piece 13, the fusion or deformation of the drive piece 13 which may occur in an electromagnetic relay 1 having large contact opening-closing current and the breakage of the drive piece 13 due to mechanical shock can be avoided.

Title: Value adjusting method for concrete calorific
Inventor: TAKEUCHI HIKARI
IPC: C08F220/04
Filed: 1990-02-07
Abstract: PURPOSE:To make the progress of hydration reaction slow and prevent the concrete from generating temperature cracks at the time of placing by feeding the whole or a part of concrete to be added primarily to concrete in the form of being contained in water absorption polymer which wraps water in its structure and remains in the shape of particles even in the water absorbing state. CONSTITUTION:When concrete is placed, the whole or a part of the amount of water to be added primarily to the concrete is fed in the form of being contained in a water absorption polymer which wraps water in its structure and remains in the shape of independent particles even in the water absorbing state. The concrete is placed in said state, and hydration reaction of concrete is started with the amount of water to be added primarily to concrete minus the amount of water contained in the water absorption polymer. After that, the water in the state of being wrapped in the water absorption polymer is discharged out gradually to complete the hydrated solidification of concrete.

Title: Pump
Inventor: SHINPO HIROMITSU
IPC: F04D13/00
Filed: 1994-02-25
Abstract: PURPOSE:To prevent a pump member from thermal expansion which occurrs because of a temperature rise of liquid retained in a discharge pipe by providing a hole which liquid retained in the discharge pipe by means of the rotation of an impeller provided downstream from the impeller and a means to open/ close the hole. CONSTITUTION:In a pump for draining rainwater, air is drawn from a bell- mouth 9 when a water level becomes below a water absorption level during its operation so that drain action is stopped, however, the temperature rise of retained water retained in the discharge pipe is caused because an impeller 10 is rotated at its full speed. A hole 12a for draining is opened to the casing 12 of the impeller 10 upper part, and also a ring 5 having a hole opened for opening/closing the hole 12a is provided on the casing 12. The hole 12a for draining is freely opened/closed by circumferentially moving the ring 5 along a rail 6 so that water retained in the discharge pipe can be drained and closed, thus thermal expansion of each pump member is efficiently suppressed.

Filed: 1995-01-26
Abstract: PURPOSE: To provide a cooking utensil for heating by electromagnetic induction which has no trouble accompanied by the existence of an immersion pipe and which can be used for a nonmagnetic pot. CONSTITUTION: A cooking utensil 1 for heating by electromagnetic induction comprises: a heating coil 17 installed on the outer surface of a heating tank 3; a power source 23 for supplying the heating coil 17 with a high frequency electric current; and a heating element 11 immersed in a cooking liquid 8 within the heating tank 3 so as to oppose to the heating coil 17 with a heating element wall 5 or a bottom 10 interposed therebetween. When the high frequency electric current is sent to the heating coil 17, an alternating field turning around the heating coil 17 is generated. A magnetic line of force of the magnetic field passes through the heating element 11, and an eddy current flows in the heating element 11. As a result, the heating element 11 is heated by Joule heat.  Since the heating element 11 is immersed in the cooking liquid 8 within the heating tank 3, the heat from the heating element 11 is transmitted directly to the cooking liquid 8 which is thereby heated.
