Title: Method of producing light-weight slag
Inventor: KADONA IZUMI
IPC: C04B5/06
Filed: 1978-08-02
Abstract: PURPOSE:To produce light-weight slags by adding TiO2 to blast furnace slags and cooling or water granulating the same. CONSTITUTION:To molten blast furnace slags there is added  2 to 15% by weight of TiO2. When TiO2 is substantially dissolved in blast furnace slags, water is injected thereto immediately to quench and pulverize the same.

Title: Crystalline defect evaluation of silicon single crystalline substrate
Inventor: MAJIMA MASAKI
IPC: C30B33/00
Filed: 1996-03-22
Abstract: PROBLEM TO BE SOLVED: To enable evaluation of crystalline defects simply, quickly and at a low cost, by etching a silicon single crystalline substrate a copper deposited on the surface thereof by an alkaline solution, and observing the surface of the silicon substrate visually or by an optical microscope. SOLUTION: A silicon single crystalline substrate 1 is immersed in a solution containing fluoric acid, and a natural oxide film 2 formed on the surface thereof is removed. Then, a copper 4 is deposited on the surface of the silicon single crystalline substrate 1 from which the natural oxide film 2 has been removed. Then, the substrate 1 with the copper 4 deposited thereon is immersed in an alkaline solution. Thus, since the copper deposited on the surface of the substrate 1 is peeled off, the surface of the silicon substrate 1 is exposed and etched. In this case, since a crystalline defect part where copper precipitates are formed is etched at a higher rate than a part having no defect, the crystalline defect part after etching may be observed as an etch pit 5 by an optical microscope.

Title: Energy scattering signal eliminating circuit
Inventor: SODEYAMA CHIYUUICHI
IPC: H04N5/16
Filed: 1981-06-19
Abstract: PURPOSE:To reproduce an output waveform with fidelity and to sufficiently eliminate an energy scattering signal, by branching an output of a video signal into two and making the capacitance value of capacitors used for a clamp circuit connected to each output terminal different. CONSTITUTION:A video signal applied to an input terminal 7 is branched into two at a distribution circuit 8 and they are respectively applied to a peak clamp circuit 9 and a pulse clamp circuit 11. The peak clamp circuit 9 consists of a diode and a capacitor of a comparatively large capacitance value and eliminates most of the energy scattering signals superimposed on the video signal and reduces the level fluctuation of the peak value of a synchronizing signal. The pulse clamp circuit 11 consists of a capacitor with comparatively less capacitance value, and the residual of the energy scattering signal and sag produced by the capacitor with small capacitance can be eliminated by applying a synchronizing signal obtined from a synchronizing separation signal circuit 10 as a gate pulse.

Title: Thin film el element
Inventor: MIKAMI AKIYOSHI
IPC: H05B33/20
Filed: 1988-04-15
Abstract: PURPOSE:To make it possible to excite a light emitting center in a resonating manner when electron hole pairs formed in a light emitting layer are reunited and to enhance light emitting luminance by forming an area having an inhibiting zone width smaller than that of other parts on the light emitting layer. CONSTITUTION:A light emitting layer 10 has a ZnS:Tb layer 4 interposed between CaS:Tb layers 11a, 11b and having a smaller inhibiting band width than that of the CaS:Tb layer. This arrangement causes electron hole pairs produced in the light emitting layer 10 to be dissociated by a high electric field and move in the direction opposite to each other. In the process of the movement, electrons strike and excite directly a light emitting center material. The electrons and the hole pairs are reunited in the layer 4 of the narrow inhibition band width and transmit energy to the light emitting center material in a resonating manner. As a result, high efficiency energy transmission to the light emitting center material becomes possible and light emitting luminance is enhanced.

Thus, the lens is stably stopped at the target position while increasing the ratio of the area where the lens can be moved at a high speed.
