Title: Hot air heater
Inventor: YAMAMOTO TERUO
IPC: F24H3/06
Filed: 1990-11-29
Abstract: PURPOSE:To control a blowing temperature so as to get a comfortable hot air feeling by a method wherein a hot air heater is comprised of a blowing temperature changing- over device and a control circuit for comparing a set value with a blowing temperature, reducing the number of rotation of a blower when the blowing temperature is low and increasing the number of rotation when the blowing temperature is high. CONSTITUTION:An indoor temperature signal of an indoor temperature sensor near a suction port and a set indoor temperature signal set by an indoor temperature setting device 10 are inputted to a control circuit 8. Detected indoor temperature is compared with the set indoor temperature, and signal of degree of opening corresponding to the temperature difference is given to a proportional valve 7 in such a way as the indoor temperature is equal to the set indoor temperature. A blowing temperature sensor 11 and a blowing temperature changing-over device 12 for changing-over a set temperature value of the hot air to the high and low stages of set temperatures are connected to the control circuit 8. An electrical motor 13 for driving a convection air blower 3 receives a signal for controlling the number of rotation outputted by the control circuit 8 in reference to a result of comparison between the detected blowing temperature and the set value then its number of rotation is controlled under a phase angle control.

Title: Measuring method for metal impurity in gas
Inventor: MIYAZAKI KAZUYUKI
IPC: G01N1/34
Filed: 1990-11-29
Abstract: PURPOSE:To measure the metal impurity in gas with high accuracy by collecting the metal impurity in the gas by porous polymer beads and subsequently quantifying the metal inpurity taken in a solution. CONSTITUTION:As porous polymer beads, a packing agent for a gas chromatograph can be used as it is and there is no limit with respect to a sample gas to be measured. For example, after poravac Q is washed, a column 11 is packed with it to be interposed between a gas container 1 and an absorbing solution (dilute hydrochloric acid) 5. Then, 2l of the sample gas containing 10% of BCl3 is allowed to flow through nitrogen gas at a rate of 0.1 l/min at room temp. Dilute hydrochlric acid is allowed to flow through the detached column 11 to take in the metal collected by the porous polymer beads and the content of the metal in the solution is measured by an ICP light emitting analyser and an FLAAS device. At the same time, the content of the metal in the solution is quantified and the amount of the metal impurity passed through the column 11 is measured. By this method, the adverse effect on analysis due to the kind of the sample gas can be prevented and metal having a particle size of 0.05 mum or less can be collected.
