Title: Continuous casting method
Inventor: NOMURA SUSUMU
IPC: B22D11/01
Filed: 1980-05-08
Abstract: PURPOSE: To cool the molten metal stored in a vacuum pump as static flow, prevents is oxidation and improve yield by flowing said metal out into a cooling medium through the conduit of the bottom side.  
     CONSTITUTION: The molten metal 4 stored in a vacuum pump 3 is introduced without disturbance into the cooling medium 2 of a tank 1 in the form of static flow of a strip of rod shape owing to the balance between the degree of vacuum of the pump 3 and the channel area of a conduit 5, whereby it is cooled for a required time to an ingot. At this time, the filmlike molten metal is obtained continuously in static flow, and it is also possible to perform oxidation prevention simultaneously with cooling in this state. It is equally well to regulate flow rate with a valve by using a storage tank in place of the pump 3. The similar effect is obtainable, too, by the use of an inert gas layer or water-cooled conduit as the cooling medium.

Title: Near field optical recording medium
Inventor: IRIE MASAHIRO
IPC: G11B7/24035
Filed: 1999-03-09
Abstract: PROBLEM TO BE SOLVED: To make a recording medium writable in a high density and with a high sensitivity and readable and reproducible many times without the destruction of recording by incorporating a photoacid generating agent and a fluorescent pH indicator into a part to be recorded and further, incorporating a sensitizer at need therein. SOLUTION: The photoacid generating agent is preferably at least one kind selected from among an onium salt, organic halogen compound, nitrobenzyl ester and sulfonate of polyvalent phenol. If the photoacid generating agent does not have absorption in a visible part or if the absorption is small, the sensitizer having the absorption in the visible part is combined. The fluorescent pH indicator emits fluorescence by the photoexcitation of the wavelength longer than the wavelength of the absorption peak of the sensitizer. Namely, the destruction of the recording does not occur even if the recording and reproducing of many times are executed even in the case of the fluorescent indicator having the absorption on the wavelength side longer than the wavelength of the sensitizer and not having photoreactivity.

Title: Vibrator holding structure
Inventor: SARUWATARI CHIKARA
IPC: H04W84/02
Filed: 1997-02-28
Abstract: PROBLEM TO BE SOLVED: To reduce the number of parts and working man-hours to realize cost reduction and protection of vibrator, by integrally forming a motor holder to accommodate a motor of vibrator together with a housing case of electronic apparatus, and then loading a motor engaged with an elastic tube to a motor holder. SOLUTION: A motor holder 17 is formed integrally with a housing case 18. Therefore, only a single process is required. A motor 13 is loaded to the motor holder 17 under the condition that an elastic tube 25 is engaged. As a result the elastic tube 25 fills the gasp between the motor holder 17 and the motor 13, thereby, when the apparatus is dropped, preventing the vibrator 12 to be released from the motor holder 17 due to the impact. In addition, loading of the vibrator 12 to the motor holder 17 can be adjusted to the tight or to the loose condition by adjusting thickness of the elastic tube 25. Moreover, when the apparatus is dropped, the elastic tube 25 works as a shock absorber not easily transmitting the external impact to the vibrator 12.

CONSTITUTION:An SiO2 layer 14 is formed by an atmospheric pressure CVD method using SiH4 and O2 as reacting gas. In the SiO2 layer 14 made by the atmospheric pressure CVD method, the lower part and its vicinity of a gate electrode 3g are thin, and the upper part and its vicinity of the gate electrode 3g are thick. Namely, when the upper part and its vicinity of the gate electrode 3g are formed so as to have a thickness of 0.5mum, the lower part and its vicinity of the gate electrode 3g are formed so as to have a thickness of only about 0.2mum. Then, anisotropic etching is performed on the SiO2 layer 14 by RIE using CF4 and O2 as reacting gas. Thus a side wall layer 4 comprising SiO2 is formed. The part of the side wall layer 4 other than the side surface of the gate electrode 3g is removed. With respect to the gate electrode 3g, the upper part of the side wall layer 4 is made to remain thick, and the lower part thereof is made to remain thin.

Title: Electric water heater
Inventor: MURAKAMI YOSHIKAZU
IPC: A47J27/21
Filed: 1986-03-20
Abstract: PURPOSE:To detect the amount of liquid accurately, by absorbing infrared rays incident through a liquid level display window from outside the body by the liquid level display window with a see-through surface thicker at a part thereof and having infrared rays absorbing function as a whole. CONSTITUTION:The thickness of a see-through surface is about 4-5mm at a thick part 28 and about 2.5mm in the remaining portion. This makes the infrared by absorption capacity of the thick part 28 greater than that of the other part of the see-through surface. The see-through surface of a liquid level display window 13 has a transmission factor of about 10% at the part thick 2.5mm with the wavelength of 900mum, hence, possessing a roughly V-shaped absorption property. Especially, a part of the see-through surface of liquid level display window 13 is made thicker at the position and in the width corresponding to the worst angle range of incidence of light entering a light receiving element 11 from outside to further enhance the prevention capacity of mulfunctioning. Therefore, even when the body is placed near a light source containing infrared rays such as incandenscent lamp, it is free from the effect of infrared rays thereby enabling accurate water supply detection.
