Title: Cherenkov-type wavelength converter element
Inventor: YAMANAKA YUTAKA
IPC: H01S3/109
Filed: 1991-02-07
Abstract: PURPOSE:To obtain parallel light having good uniformity with little limitation for practical use by specifying the length of a waveguide element. CONSTITUTION:In a concentrical fiber-type waveguide element having nonlinearity in at least one of core 2 or clad 1, wavelength of the guided light is converted by Cherenkov-type phase matching. The Cherenkov radiation angle fiber radius r and waveguide length L are determined to satisfy r/L<tan theta<=2r/L. When L is increased, converted light generated near the incident end for the exciting light 3 is reflected by the outer circumference of the clad 1 and again converged into the core 2. By selecting L to satisfy tan theta<=2r/L, reflected light emits from the fiber end before the light reaches to the core 2 so that no loss of converted light is caused by absorption of the core. Although beams of two different directions overlap at the fider end, this problem can be solved by providing an Axicon lens 5 at a certain distance from the fiber end, and thereby, parallel beams with little dark area can be obtd. which causes little limitation for practical use.

Title: Electronic currency, method for using the same, electronic currency system and storage medium
Inventor: MIYATA HIROKI
IPC: G06Q40/02
Filed: 1999-01-26
Abstract: PROBLEM TO BE SOLVED: To make an electronic currency able to function as a prepaid card(PC) and to suppress an illegal use by the third person by taking the function of PC into electronic currency. SOLUTION: When a user purchases the PC of a company A for a-yen within the amount of the remainder (Z-yen) of electronic money (S1), the remainder of electronic money of an IC card becomes (Z-a)-yen. Besides, when the premium of α-yen is put to the PC, the usable amount becomes (a+α)-yen (S2). Further, the user registers a password number which is effective only when utilizing the PC of the company A (S3). In the case of shopping for X-yen while utilizing the PC of the company A (S4), X-yen is preferentially subtracted from the remainder of the PC (S5).  At such a time, when the subtraction is disabled because of lack of the remainder (S6), the presence/absence of automatic update setting to the IC card (S7) and the presence/absence of novel PC purchase will (S9) are judged and when the both are absent, a difference is subtracted from the electronic money side of the IC card (S11).

Title: Treatment of waste water containing nitrate
Inventor: SAKAMOTO SHUICHI
IPC: C02F1/70
Filed: 1993-02-04
Abstract: PURPOSE:To enable an efficient treatment of a high concd. waste water in the decomposing method of nitrate by adding a gaseous hydrogen to the waste water containing nitrate and by heating under the presence of a catalyst. CONSTITUTION:More gaseous hydrogen is added to the waste water than its solubility. In this way, because the gaseous hydrogen is added in excess and a reaction progresses in the state where the bubbles of the gaseous hydrogen presents in a catalyst layer, when the dissolved hydrogen in a liq. phase is consumed by the reaction, the hydrogen equivalent to the consumed volume is transferred from a gas phase to a liq. phase, the dissolved hydrogen is replenished gradually. In this way, by the sufficient supplying of the gaseous hydrogen, the waste water is decomposed efficiently even in the high concd. waste water.

Title: Structure of coke oven lid part
Inventor: SHIHARA YASUTAKA
IPC: C10B25/06
Filed: 1990-01-25
Abstract: PURPOSE:To improve the productivity of a coke oven and to stabilize the quality of coke by ensuring a sufficient length of a gap between an oven wall and a coking plate and narrowing the coking plate towards a louver formed on an oven lid plug. CONSTITUTION:By ensuring a sufficient length l of a gap between an oven wall and a coking plate, coal is prevented from entering through this gap into a space of the coking plate due to a frictional force between coal and the oven wall and between coal and the coking plate. Steam and gas generated near the widthwise center of a carbonization chamber are passed through the louver and introduced into the space of the coking plate, while steam and gas near the oven wall are passed through the gap into the space of the coking plate. Due to the coking plate and an inclined surface structure towards the opening end of a louver structure, the flow of gas into the gap is facilitated so that the acceleration of carbonization near the end of an oven lid can be realized. In addition, a decrease in the coal layer near the end of an oven lid, where carbonization proceeds slowly, can also be accomplished due to the inclined structure.

IPC: H04N19/61
Filed: 1989-01-30
Abstract: PURPOSE:To improve the encoding efficiency by using correlation remaining between the transform coefficients of blocks which belong to a macro block. CONSTITUTION:Symmetric components of even/even, even/odd, odd/even, and odd/odd in horizontal and vertical directions are found from the signal of the macro block, and different linear transformation corresponding to those components, for example, discrete cosine transformation on the even symmetric component, discrete sine transformation on the odd symmetric component are performed. In other words, the content of a memory is segmented setting the macro block consisting of (2NX2N) picture elements as a unit, and difference with the macro block nearer to the content of a transmitted frame is calculated by a subtractor 4. The output of the subtractor 4 is transformed to four components based on even symmetric and odd symmetric characteristic in the horizontal and vertical directions, and the four components are transformed to coefficients corresponding to (NXN) frequency components, respectively by an orthogonal transformation circuit 8. In such a way, the encoding efficiency can be improved by using the correlation between the transform coefficients of the blocks.
