Title: Wafer washing method
Inventor: MARUYAMA NOBUAKI
IPC: H01L21/304
Filed: 1982-01-14
Abstract: PURPOSE:To obtain uniform washing effect by controlling rotating movement of the washing liquid spraying nozzle at the wafer surface. CONSTITUTION:A nozzle 12 which sprays a washing liquid 14 gradually increases the speed when it rotatingly moves to the center c from the periphery a1 of wafer 11 and then gradually decreases the speed when it returns to the periphery a2. Thereby, the washing liquid 14 can be equally supplied onto the wafer 14 where the peripheral speed is different in the periphery and the center and there is no such a chance that the washing liquid is concentrated to a part of surface and accordingly the surface is damaged.

Title: Measurement of specific resistance distribution for silicon crystal
Inventor: OOSAWA AKIRA
IPC: H01L21/66
Filed: 1980-01-22
Abstract: PURPOSE:To measure the distribution of the specific resistance by a resistance method by applying a specific heat treatment to a P type si crystal of 1-50OMEGAcm made by czochralski method. CONSTITUTION:The concentration of a P type dopant depends on the location. A heat treatment is applied to a CZSi crystal at 400-500 deg.C to convert O2 in the crystal to an electric thermal doner thereby compensating for the carrier. As the distribution of the specific resistance is in inverse proportion to the difference between the concentrations of the dopants, the measuring sensitivity can be increased thereby enabling measuring of evenness of the specific resistance up to a range previously impossible to do.

Title: Fluidized combustion furnace
Inventor: KITAMI SEIICHI
IPC: F23G5/30
Filed: 1978-01-24
Abstract: PURPOSE:To provide a fluidized combustion furnace, in which a multiplicity of water nozzles are  provided at an upper portion of combustion chamber so as to inject water from the nozzles and  thus to cool the combustion gas, whereby it is enabled to make an efficient use of the installation  space, since it is not necessary to provide a special chamber for treating dust containing water or for cooling the combustion gas. CONSTITUTION:A plurality of water nozzles 6 are provided in the side wall of a fluidized combustion furnace at a portion thereof located upwardly of combustion chamber 5. High-temperature  combustion gas generated from the combustion chamber 5 is cooled by mist-like water particles  ejected from nozzles 6 when water is evaporated into vapor while absorbing evaporating heat,  and the combustion gas thus cooled is discharged from the furnace through gas cooling section 7. Subsequently, dust removing treatment is applied to the combustion gas. Here, if water ejected  from nozzles 6 is not completely evaporated in the combustion chamber and drips downward in  the furnace or along the furnace wall, water drips are evaporated completely by the high-temperature combustion gas flowing upward in the furnace together with heat keeping function of the  furnace itself, so that water drips can be evaporated completely and therefore water is not discharged to the outside of the system in the least. Further, bacause of the arrangement that water  ejected from nozzles 6 and combustion gas flow in opposite directions to each other in the furnace,  space for the gas cooling section 7 can be considerably small.

Filed: 1982-01-19
Abstract: PURPOSE:To prevent the diffusion of carriers generated in the light absorbing layer of a photodiode, and to improve quantum efficiency by forming the light absorbing layer only to a section just under a light receiving section. CONSTITUTION:The n<-> type InGaAsP light absorbing layer 2 is formed onto an n<+> type InP substrate 1. An n<-> type InP window layer 3 is liquid-epitaxial grown onto the substrate 1 and the light absorbing layer 2, cadmium is diffused selectively onto and around the light absorbing layer 2 in the window layer 3, and the light-receiving section 4 is formed. Since the light absorbing layer 2 is limited to the section just under the light-receiving section 4, carriers generated in the surface of the light absorbing layer 2 do not diffuse along the direction parallel with the layer by the absorption of light projected into the light-receiving section 4, and carriers expiring by recombination are reduced. Accordingly, the quantum efficiency of the photodiode is improved.

IPC: G06F3/0354
Filed: 1990-01-17
Abstract: PURPOSE:To efficiently input-control a mouse by detecting pressure added to the mouse and dynamically changing an electric signal showing a distance and a direction by means of the actual shift of the mouse. CONSTITUTION:A first electric signal generation circuit 3 converts the detection result of the shifted distance and direction of the mouse by a shift detection part 2 into the electric signal. A pressure detection part 4 detects pressure added to the mouse and a second electric signal generation part 5 converts the detection result by the pressure detection part 4 into the electric signal. An electric signal synthesis part 6 amplifies and outputs the electric signal outputted from the first electric signal generation part 3 by the electric signal outputted from the second electric signal generation part 5 corresponding to added pressure. Thus, the mouse cursor on a display device can be shifted large or small by pressure added to the mouse when the mouse shifts, and the efficient input control of the mouse is attained.
