Title: Formation of semiconductor film
Inventor: TOMITA KENJI
IPC: H01L21/20
Filed: 1989-06-21
Abstract: PURPOSE:To manufacture a semiconductor film economically by a method wherein an amorphous semiconductor film containing impurities and, in addition, an insulating film of a high impurity concentration are formed by using a vapor growth method and they are irradiated with a laser or the like so as to be crystallized. CONSTITUTION:A p-type amorphous silicon film 2 is formed on a borosilicate glass substrate 10 at a proper temperature by using a CVD method after disilane and diborane have been mixed and a flow-rate ratio has been set in such a way that an impurity concentration in a film is 1X10<15> to 10<17>cm<-3>. Then, a flow-rate ratio of a mixed gas of silane and CO2 is set in such a way that an impurity concentration in a film is 1X10<18> to 10<21>cm<-3>; an insulating film 4 is formed on the film 2 by using a plasma of a glow discharge. Prescribed parts of the film 4 are removed; after that, the film 2 is irradiated with an energy beam such as a laser or the like and is melted instantaneously; an n-type impurity diffusion layer 3 is formed in parts in which the patterned film 4 comes into contact with the film 2; the film 2 becomes an amorphous silicon film 12. Then, a source electrode S, a drain electrode D and a gate electrode G are formed on the films 12, 4 by a vacuum vapor-deposition operation or the like. Thereby, a semiconductor film can be manufactured economically.

Title: Air conditioner
Inventor: OSADA MINORU
IPC: F24F11/02
Filed: 1994-07-12
Abstract: PURPOSE:To obtain an air conditioner in which the abnormal rise of a high pressure side pressure at the time of heating can be effectively suppressed while shortening a time taken for release while reducing the frequency of the release, hence a heating efficiency can be improved and a wet vapor suction can be prevented as much as possible. CONSTITUTION:At the time of heating, when the temperature Tc of an indoor heat exchanger 5 (condenser) is raised to 60 deg.C or higher, a release signal is generated. When the temperature Tc of the exchanger 5 is dropped thereafter to less than 58 deg.C, a release cancel signal is generated. In the case of generating the release signal, the speed of an outdoor blower 6 is reduced at each predetermined time such as each one minute. The speed reducing width of the blower 6 is largely set as compared with that at the following time of decreasing. When the release cancel signal is generated, the speed reduction of the blower 6 is cancelled.
