IPC: G01N31/12
Filed: 1992-06-18
Abstract: PURPOSE:To obtain a film thickness measuring method by which the thickness of an oxide film on the rear surface of a semiconductor wafer can be measured. CONSTITUTION:When a silicon oxide film is formed on the rear surface of a silicon substrate after an epitaxial layer is formed on the front surface of the substrate, a semiconductor wafer sample S is inserted into a graphite crucible 2 placed in a sample chamber 3 and the sample S is melted by heating the crucible 2 with a heater 4 while a carrier gas is introduced into the crucible 2 so that oxygen atoms can combine with carbon atoms of the crucible 2 into carbon monoxide molecules. Then the carbon monoxide molecules are oxidized into carbon dioxide molecules in a carbon monoxide oxidizing tube 7 and the amount of the carbon dioxide molecules is measured with an infrared detector 8. The measured amount of carbon dioxide molecules is inputted to a measuring and arithmetic instrument 10 and the instrument 10 finds the thickness of the oxide film.

Title: Cmos voltage converting circuit
Inventor: KOIKE HIDEJI
IPC: H03K5/02
Filed: 1983-08-31
Abstract: PURPOSE:To obtain a voltage converting circuit which transmits an input signal at a high speed and has low power consumption, by inputting the input signal and a signal, which is obtained by adding a certain voltage to the input signal, to a CMOS circuit through voltage limiting FETs respectively. CONSTITUTION:When an input Vi is lower than a voltage V1-VTN1 (VTN1 is the threshold value of a FETT1), the FETT1 is turned on and an FETT2 is turned off, and therefore, the potential at an output point E is V4. When the input Vi becomes higher, both FETs are turned off, and the potential at the output point E is held in V4. When the input V1 is higher furthermore to exceed a voltage ¦VTP2¦+VF+V2-V3, the FETT2 is turned on, and therefore the potential at a point D becomes V3-VF+Vi, and the potential at the output point E becomes 0. On the contrary, when the input Vi is lower, the potential at the output point E is held 0 until the input Vi is lower than V1-VTN1, and therefore, hysteresis is given, and rise and fall of the output are made sharp to transmit the signal at a high speed.

Title: Method for cooking rice
Inventor: MIYAKE KAZUYA
IPC: A23L7/10
Filed: 1993-06-29
Abstract: PURPOSE:To prevent cooked rice from boiling over and scattering on the cocking of the rice. CONSTITUTION:The temperature of a container 6 is detected with a container sensor 18. The temperature of the upper space of the container 6 is also detected with a lid 22. When the container sensor 18 and the lid sensor 22 reach prescribed temperature conditions, the application of an electric current to a rice- cooking heater 15 for heating the container 6 is temporarily stopped. After the heating stoppage period an electric current is again applied to the rice- cooking heater 15 to boil the rice. During the heating-stopping period the rice quickly absorbs water to uniform the whole temperature of the container 6. Thereby, the amount of the water remained in the container is reduced, when the rice is again boiled, and the boiling of the rice over the container can be prevented.
