Title: Fixing device
Inventor: KASAMA NOBUHIRO
IPC: G03G15/20
Filed: 1979-04-05
Abstract: PURPOSE:To enable a suitable amount of an offset-preventing agent to be coated readily by the simple constutition of giving the resistance for the driven revolution of a roller for conveying the offset-preventing agent independently from the resistance by the other member for conveying the offset-preventing agent. CONSTITUTION:When there is no silicone oil on the peripheral surface of a roller 1, the friction force between the heating roller 1 and coating roller 6 causes the roller 6 to be driven by the revolution of the roller 1 and revolve against the friction resistance by a felt 9 and brake blocks 13, 14. As a result of this, silicone oil is coated from the felt 9 to the roller 1 by way of the roller 6. When the amount of oil becomes close to the required value, the driven rotating force of the roller 6 becomes weak against the resistance by the felt 9 and brake blocks 13, 14 and this results in that the roller 6 slowly revolves while slipping on the peripgeral surface of the roller 1 and further when the amount of oil reaches the required value, the roller 6 stops being driven and revolved.

Abstract: PURPOSE:To improve the machining accuracy of mirror surface by applying metal spraying to a male die mirror surface with excellent surface accuracy so as to form a conductive layer with uniform thickness, closing the female die and injecting and forming a thermoplastic resin in the cavity in the die. CONSTITUTION:When a mold releasing agent 8 is applied to a mirror surface 7 of a male die, a metal spray material is jetted thereupon to form a conductive layer 4. Very uniform surface layer and thickness are attained for the conductor layer 4 since metal spray is applied to the mirror face 7 of the male die with high surface accuracy. A cavity 12 is formed between both the male die 6 and a female die 10 having a nozzle 11. Then an injection molding machine 13 is used to inject the resin in a resin chamber 17 into the cavity 12 of the metallic die, and when the resin cooling is finished, the metallic die is opened and the forming is removed from the die. The conductive layer 4 having uniform thickness and a smooth face is formed on a parabolic face 2 of the forming body and a decoration layer 5 is formed on the surface of the conductive layer 4 of the forming. Thus, the mirror surface accuracy is improved.

Abstract: PURPOSE:To provide self-testing function for deciding a quality of an integrated circuit device by providing a pseudo random pattern generating circuit on the integrated circuit device, generating a testing data and an address signal, wiring them temporarily in a storage circuit, and comparing them with its output. CONSTITUTION:A storing circuit 200 is set to a write mode by inputting a ''1'' level signal to a mode switching terminal T and an an R/W terminal. When a write pulse is inputted to a WE terminal, a pseudo random pattern generating circuit 500 starts to operate. An address signal generating circuit 300 generates a testing address signal. In the same way, a testing data signal is generated by a data signal generating circuit 400. In this way, the testing data signal is written in a designated address of the storing circuit 200, and also outputted through an output signal line group 708. When the write pulse becomes a ''0'' level state, a comparing circuit 600 compares it with the previous testing data signal, and the result is outputted to an output terminal 801. In this way, provision of an expensive testing machine is made unnecessary.

Abstract: PURPOSE:To reduce an air resistance, to decrease a load to a fan motor and to prevent generation of mildew and offensive odor of a humidifier element by so installing the humidifier as to incline it to an air flow in a vent passage and to form a gap between an outer periphery and a sidewall of the passage. CONSTITUTION:A prefilter 6, a main filter 7, a heat exchanger 8 and a humidifier 9 are sequentially installed from an atmosphere intake port 2 or a circulating intake port 3 side in a vent passage 5 from the port 2, 3 to a discharge port 41. The humidifier 9 is so inclined to an air flow as not to become a blocking state and to reduce the air resistance, and so installed that its outer periphery is not brought into contact with four sidewalls 51 for forming the passage 5. As a method for installing the humidifier, a method for placing and fixing it on a gate frame 91 is employed. Thus, since most of the air passed through the exchanger is passed through a gap between the outer periphery of the humidifier and the sidewalls of the passage, a ventilating pressure loss is small.
