Title: Manufacture of semiconductor substrate
Inventor: KASAI NAOKI
IPC: H01L21/74
Filed: 1985-03-28
Abstract: PURPOSE:To obtain a flat semiconductor substrate by depositing a film having the quality of materials different from an insulating film on the insulating film formed onto a substrate, the surface thereof has an silicon single crystal layer, and removing the deposit film on the insulating film before an silicon film is grown in an epitaxial manner. CONSTITUTION:A film 3 having the quality of materials different from an insulating film 2 functions as a stopper to ion implantation even in a process such as one in which a buried layer 5 is formed through ion implantation before a process in which a film is grown in an epitaxial manner by depositing the film 3 on the insulating film 2, thus avoiding the implantation of impurity ions onto the insulating film in a section not coated with a mask. Impurity auto- doping during the epitaxial growth process is reduced by removing the film 3 before epitaxial growth, and a flat silicon semiconductor substrate 1 having no irregularity is acquired.

Title: Air conditioning apparatus
Inventor: OKAMURA MAMORU
IPC: F24F11/02
Filed: 1981-04-25
Abstract: PURPOSE:To enable to automatically change-over the setting of operating temperature  of a cooling apparatus or a heating apparatus by a method wherein an auxiliary apparatus, which selectively operates interlocked with an operating temperature changing- over means which changes-over the operating temperature of the cooling apparatus or  the heating apparatus. CONSTITUTION:When a cooling machine C and a fan F are simultaneously put in operation, a switch SW1 selects a resistor R1, which results to lower the operating temperature of the cooling machine C. On the other hand, when only the cooling machine C is  put in operation, the switch SW1 selects a resistor R2, which causes to raise the operating temperature of the cooling machine C by the ratio equal to the ratio of the ohms  of the resistor R2 to those of the resistor R1. Accordingly, when the resistances of the  resistors R2 and R1 are determined so that the ratio of the ohms of the resistor R2 to  those of the resistor R1 corresponds to the rise of the operating temperature of the  cooling machine C of 1-2 deg.C, the operating temperature of the cooling machine C is  automatically raised by putting the fan F in the simultaneous operation with the cooling machine C and the operating temperature of the cooling machine C can automatically be returned to the former temperature by getting the fan F out of the simultaneous operation with the cooling machine C.

Title: Infrared detector
Inventor: SHIBATA KENICHI
IPC: G01J1/42
Filed: 1986-03-20
Abstract: PURPOSE:To measure the amount of infrared rays accurately in a short time, by providing a synchronous rectification circuit which picks up an infrared rays detection signal synchronizing the opening or closing of an optical shutter, a peak value holding circuit, a valley value holding circuit and a peak value and valley value addition circuit. CONSTITUTION:An output of a synchronous rectification circuit 6 is inputted into a peak value holding circuit 7 and valley value holding circuit 8 to hold a peak value and a valley value respectively. The peak and valley values held are inputted into an addition circuit 16 to get the sum of both the values. An output of the addition circuit 16 gives an external output of an infrared detector 1. For example, an output signal of a room temperature measuring device 4 corresponds to a measured value of the temperature of atmosphere and a signal voltage thereof is inputted into the addition circuit 16 via an amplifier 15 to add to the peak value and the valley value for the correction of a detection value of an infrared detection element 2. Thus, erroneous measurement can be avoided otherwise caused by being mixed with a noise by holding a peak value and a valley value only for a sampling time period.
