Inventor: WATANABE MASAHIRO
IPC: H01L21/66
Filed: 1985-08-21
Abstract: PURPOSE:To measure the life of a minority carriers in a fine part at a high accuracy, by a method wherein an exciting light is made to irradiate a semiconductor with the modulated intensity to generate a motive force and only the portion due to the minority carriers are extracted from potential variations in the motive force to detect the phase thereof. CONSTITUTION:An exciting light A from a laser 2 is passed through an optical tone modulator 4 to be modulated by a modulating signal C with the modulation frequency from a signal generator 3 to turn to an intensity modulated light B, which is made to irradiate a semiconductor 1 through a mirror 5 and a lens 6. A fine part of the semiconductor 1 is excited to generate carriers to create a double charged layer according to the structure of P-type Si and a wafer, resulting in a motive force from a surface photovoltage. Potential variations in the motive force are detected with an electrode 8 and led to a lock-in amplifier 10 through an amplifier 9 to detect the phase only about the frequency component the same as that of the modulating signal C from the signal generator 3. Thus, the life of the carriers at the fine part can be measured at a high accuracy with the phase detection about potential variations in the electrode of the photovoltaic force of the carriers.

Title: Interpolation circuit for digital picture signal
Inventor: KONDO TETSUJIRO
IPC: H04N19/126
Filed: 1986-08-02
Abstract: PURPOSE:To ensure the interpolation of a composite color video signal by giving interpolation to the picture data on a prescribed picture element by the linear primary combination between the prescribed number of existing picture data surrounding the prescribed picture element and the prescribed number of weight coefficients and deciding the weight coefficient so that the square sum of the errors between the interpolation value and the true value is minimized. CONSTITUTION:The picture data on the thinned picture elements is estimated by the linear primary combination between the prescribed number of existing picture data surrounding the thinned picture elements within the same field (frame) and the prescribed number of weight coefficients. A weight coefficient is previously decided so that the square sum of errors between the estimated interpolation value and the true value is minimized. This weight coefficient is identified as follows. That is, plural sheets of pictures are photographed by a video camera and this photographing signal is digitized to obtain the picture data. Then this picture data is processed by an electronic computer. The number (degree number) of picture data existing at the periphery and used for identification of the weight coefficient is set in accordance with the hardware scale. Thus such a weight coefficient that minimizes the square sum of errors is identified by setting said degree number.

Title: Heating system of drink or food
Inventor: KUBOTA YOSHITAKA
IPC: A47J36/02
Filed: 1999-06-29
Abstract: PROBLEM TO BE SOLVED: To quickly heat drink or food without deteriorating quality of the drink or the food even by an AC 100 V type power source by holding a vessel for containing the drink or the food in a tank for storing a high temperature liquid, and rotatably moving the vessel. SOLUTION: First of all, a prescribed quantity of water is put in a tank 1, and the water is heated by carrying an electric current to an electric heating heater 8 to be turned into high temperature hot water. When a hot water temperature reaches a preset temperature, the electric heating heater 8 repeats current- carrying/current-noncarrying so that the hot water temperature becomes a constant temperature. Next, a canned drink 2 is inserted into a vessel holding means 3, and a cover 7 is closed. Simultaneously when closing the cover 7, an electric current is carried to a motor 6 to be driven. The motor 6 and a rotary body lower 5 are connected so that the rotary body lower 5 rotates simultaneously with driving of the motor 6.  Thus, since an agitating effect of the drink can be promoted by rotation by using the high temperature hot water as heat for heating drink or food contained in a vessel, the drink or the food stored at quality undeteriorating temperature can be efficiently and quickly heated.

Title: Flow injection analytical method
Inventor: UCHIKI HIDEO
IPC: G01N21/75
Filed: 1982-10-20
Abstract: PURPOSE:To obtain a flow injection analytical method capable of performing accurate measurement, by a method wherein absorbancy is measured by light having a color other than that of a reaction liquid and the absorbancy of the reaction liquid is measured by light having the color same to that of the reaction liquid when the measured absorbancy reaches zero. CONSTITUTION:The change in quantity of light is monitored by a peak monitor circuit 16 by using light other than a red color, for example, by blue light as the light from a spectrophotometer 9. In this case, as a reaction liquid is flowed to a cell, the quantity of light is changed as shown by a curve. Because the blue color different from the red color being the color of the reaction liquid is used, the measurement of a light absorbing amount due to the reaction liquid itself is not participated at all. As mentioned above, blue light is changed over to the red color in a wavelength change-over circuit 17 at the point of time when absorbancy is zero in the change in the quantity of light due to blue light, that is, at the point of time (s) when lens action is not acted at all in the leading end part and the trailing end part of the reaction liquid. This measured value is the actual measured value of the reaction liquid.

Filed: 1980-12-23
Abstract: PURPOSE:To prevent conversion of an epitaxial layer on a buried layer into the P type at  afterward epitaxial growth, and to prevent deterioration of characteristic of element of a  semicondctor integrated circuit device by a method wherein after P ions are implanted in a P  type substrate, Sb ions are made to diffuse to form the N<+> type buried layer. CONSTITUTION:Openings 7 are formed in an SiO2 film 6 on the P type substrate 1, and B ions  are made to diffuse to form P type layers 4a. Then an opening 8 is formed, P ions having a  large diffusion coefficient are implanted to form an implanted layer 10, and Sb11 having a  small diffusion coefficient is adhered by the CVD method. The diffusion treatment is performed to form the N<+> type buried layer 2 being surrounded with the P<+> type layers 4a.  However concentration of P10 is selected as lower than that of Sb11. Then an N type epitaxial layer 3 is formed, B ions are made to diffuse selectively from the upper face to be connected to the P<+> type layers 4a to provide P<+> type layers 4b, and P<+> type isolation layers to surround the N<+> type buried layer 2 is completed. By this constitution, because the external diffusion coefficients of P10 and B in the layers 4a are equal when epitaxial growth is to be performed, and moreover because P has larger diffusion coefficient than Sb, the epitaxial layer 3 at the upper part of the buried layer 2 is not converted into the P type by B in the layers 4a  to prevent formation of high resistance in the epitaxial layer on the layer 2, and deterioration of characteristic of the element can be prevented.
