CONSTITUTION:A core material is a composite possessing a matrix and a glass mat and long-fiber glass respectively as a matrix and reinforcement material, which improves rigidity of the whole of a shell plate and contributes to its shape retention. These reinforcement materials may be used by arranging within a mold beforehand prior to R.RIM. Contents of these fillers are established so as to fall within a range of 30-50wt.% to a core body weight. A matter is good whatever it may be if the matter is of a polymer to be obtained as a result of the RIM as the thermosetting resin of the other element of the core material and RIM urethane, nylon RIM and epoxy RIM can be mentioned in a concrete form. A skin layer to be formed by coating the surface of a core material is constituted of the thermosetting resin formed of the RIM. In this case, when the skin layer is of the same kind as the thermosetting resin of the matrix of the core material, adhesion strength between the skin layer and the surface of the core material is improved.

Then a temperature rise in the inside of the case body 22 is earlier than that of the roast at the initial time. On the one hand, a rate of the output value of the timing element 24 which is increamental is the same as that of the roast at the initial time. Then the output value of the temperature detecting element 25 becomes lower than that of the timing element 24, that is, a time when the heater is turned OFF becomes earlier than that at the initial time. As the roasting period of time is made to vary automatically at the temperature of the inside of the case body like this, identical scorch is obtained always at the time of the continuous roast and the variation of the temperature of the open air.

Title: Compact-type fluorescent lamp
Inventor: YOSHIKAWA NOBUHISA
IPC: H01J61/56
Filed: 1984-01-23
Abstract: PURPOSE:To obtain a light compact-type fluorescent lamp of a relatively low cost by providing the emission tube with an area located near one of the electrodes and spatially connected to an outer tube globe, igniting the emission tube by an asymmetrical alternating current having a d.c. component and causing said electrode to work as an anode in terms of its d.c. component. CONSTITUTION:An emission tube 1' consisting of a so-called double-U-shaped tube has an area 13 which is located near an electrode 4 and spatially connected to an outer tube globe 3. The emission tube 1' is ignited by a chopper-system high-frequency ignition circuit in which chopper operation is repeated by the combined function of a power transistor 17, a choke coil 21, a capacitor 22 and a diode 23. During the ignition of the emission tube 1', the electrode coil 4 located near the connection area 13 works as an anode in terms of its d.c. component. Owing to the above constitution, any cataphoresis is completely prevented, thereby producing over the entire emission tube 1' a homogeneous luminous state almost the same as that produced when the emission tube 1' is ignited by a conventional alternating current having no d.c. components.
