Title: Combustion type heater for use in vehicle
Inventor: IDA HIROYUKI
IPC: B60H1/03
Filed: 1986-01-31
Abstract: PURPOSE:To make it possible to conduct blow-off of a hot air flow of good feeling from the beginning by constituting the heater in such a manner that by use of a temperature sensor, when the temperature of a heat exchanger exceeds a first predetermined value, a blower is actuated, and when the temperature of the heat exchanger exceeds a second predetermined value, it is detected that the heat exchanger is in an overheated state. CONSTITUTION:Immediately after the ignition of fuel, a blower 10 is set in a stop. Therefore, air within a compartment is not sent to a heat exchanger 2, but the temperature at the sensor 11 mounting portion of the heat exchanger 2 abruptly rises up. The temperature sensor 11 detects the temperature of the heat exchanger 2, and inputs a temperature signal to a control unit 20. When the temperature of the heat exchanger exceeds a first predetermined value, the control unit 20 inputs an ON signal to the blower 10. Accordingly, the blow-off temperature of hot air into the compartment immediately rises up to a desired value and feeling to crew members is improved. Further, since when the detected temperature of the heat exchanger 2 exceeds a second predetermined temperature, there is a possibility that the heat exchanger 2 might be damaged, the control unit 20 outputs a stop signal to a fuel pump 3 and the blower is operated more strongly than usual, thus actuating an alarm 22.

IPC: G06F13/00
Filed: 1980-02-20
Abstract: PURPOSE:To shorten the detecting time for the area of fault, by always securing a coincidence between the system displayed by a system control circuit and the system of an end office device that delivered the status. CONSTITUTION:When the system control circuit indicates the 1-system status reading, the central device control circuit 1110 turns the route discriminating data to ''0'' and renews the end office address successively. Thus the end office controllers 1210, 1310, 1510 and 1610 transmit the 1-system side status, and the 1- system status can be read out through the central device excepting the end office 1400. When the system control circuit indicates a reading of the 0-system status, the central device control circuit 1110 turns the route discriminating data to ''1'' and renews the end office address successively. Thus the end office controllers 1211, 1411, 1511 and 1611 transmits the 0-system side status, and the 0-system status can be read out through the central device excepting the end office 1300. In the case of the end office 1300, a nonresponse display of the 1-system side is obtained in the form of a nonresponse.

IPC: B29K33/00
Filed: 1993-02-08
Abstract: PURPOSE:To improve fluidity at the time of molding and to reduce compression allowance at the time of molding by using powders having two types of particle sizes to perform closest packing as polymer powder. CONSTITUTION:Deposit 40 injected in fine particle state is injected into a supply passage 2 together with hot air from a small-diameter part 20, and supplied as further finer particles by wind pressure to a drying chamber 1. The deposit 40 becoming powder as dried in the chamber 1 is gathered in a collecting bag 11. Obtained powder is repeatedly washed with pure ware and filtered to elute unreacted NaOH, AlCl3 and NaCl of reactive product, then again heated, and dried to obtain about 40g of Al ion crosslinking type polymer fine powder. Thus, the once dried metallic ion crosslinking type polymer fine powder is not agglomerated even if it becomes a wet state at the time of cleaning, but maintained in a fine state even after it is cleaned and dried. Accordingly, the obtained fine powder can be used for molding after it is cleaned and dried.
