Title: Embedded heater
Inventor: KIN RIYUUSHIYUTSU
IPC: F24D13/02
Filed: 1998-05-16
Abstract: PROBLEM TO BE SOLVED: To prevent oxidation of terminals or the like by applying a sealing material to a portion which is connected to a heating body of a cord portion. SOLUTION: This embedded heater comprises a heating body 2, a cord portion for supplying electric power to the heating body 2, and a covering portion for covering the heating body 2. And a portion connected to the heating body 2 of the cord portion is sealed by a sealing material. A power supply cord 4 is connected to the heating body 2, the heating body 2 is covered with a waterproof covering material 3 and further the inside of the covering material 3 is vacuumed. Silicone rubber or the like is used as a sealing material. Because of this, even though air enters from the tip of the power supply cord 4 and this air has reached other end of the power supply cord 4 in many years, air does not reach a terminal portion or the like beyond the other end of the power supply cord 4. Thus, oxidation and deterioration of the terminal or the like of the heating body can be prevented.

Title: Reception control system
Inventor: SUZUKI HIDEO
IPC: H04L25/40
Filed: 1985-07-11
Abstract: PURPOSE:To prevent the processing of a reception from being affected by the disturbance in a transmission clock by using an independent device clock so as to apply reception processing such as error check of a reception data or address discrimination after a transmission clock signal extracted from a data transmission signal is used to store a data in a reception buffer. CONSTITUTION:The transmission clock signal outputted to a transmission clock line 4 is fed to a buffer control circuit 15. The buffer control circuit 15 uses the frequency-divided transmission clock signal to transfer alternately the data received by a reception shift register 5 to reception buffers 10, 11 one by one byte. A receiver has a clock generating circuit 14 generating the device clock signal independently of the transmission clock signal and a reception processing section 13 transfers the reception data alternately from the reception buffers 10, 11 to the control buffer 12 under the control of the device clock signal. Thus, the disturbance of the transmission clock extracted from the transmission signal is not affected onto the succeeding processings and the reliability of the communication system is improved.
