Title: Cwm combustion device
Inventor: MASAI TADAHISA
IPC: F23D99/00
Filed: 1983-03-15
Abstract: PURPOSE:To prevent a CWM from being solidified even when it is diluted at the time of fuel change, by connecting a CWM feed pipe to the underside of purge fluid feed pipe, in a combustion device built to burn a slurried mixture (CWM) of pulverized coal and a fluid medium such as, for example, a water. CONSTITUTION:A CWM feed pipe 1 and a purge fluid feed pipe 4 are arranged to confluent at a confluence 3 by connecting them through a T-shaped joint or directly, and then elongate to a burner gun 7 through a common pipe 6. In this arrangement, the CWM feed pipe 1 is elongated to the underside of confluence 3. A CWM valve 2 is closed and a purge fluid valve 5 is opened upon the stoppage of operation. Though the CWM is supplied to the burner gun 7 by the purge fluid in the common pipe 6, no purging action is taken for the CWM during its passage between the CWM valve 2 and the confluence 3. While the surface layer of CWM is diluted by the purge fluid at or around the confluence 3, the CWM is not solidified by settling pulverized coal grains at a place remote from the confluence 3.

Title: Manufacture of semiconductor device
Inventor: OZAKI JUN
IPC: H01L27/04
Filed: 1986-02-28
Abstract: PURPOSE:To enable a groove finer than that formed by the resolving power of photolithography to be cut making elements much finer and a semiconductor highly integrated by a method wherein the second mask is formed inside the first mask formed on a semiconductor substrate anisotropically etched to cut a groove at least using the second mask. CONSTITUTION:Even if the limit of minimum dimension of an opening 5a of the first mask 5 composed of a polycrystalline silicon film 3 is reduced down to around 1mum by the resolving power of photolithography on a photoresist 4, another opening 7a is made in the second mask 7 formed from a CVD silicon oxide film 6 by the residual side-walls in the opening 5a of the first mask 5 naturally making the dimension of opening 7a smaller than 1mum. Through these procedures, the width A of a groove 8 etched using the opening 7a as a mask is specified to be around 0.5mum, a much finer value than that specified by the resolving power of photolithography.

Abstract: PURPOSE:To form a shallow junction having preferable characteristics by forming a Ti silicide layer in a region formed of a diffused layer, and then selecting injection energy to have concentration peaks under and on a boundary between the Ti silicides of specific substance and P-, N-type diffused regions and silicon. CONSTITUTION:A Ti silicide layer 6 is formed by a thermal reaction of Ti with Si on silicon 1 having 10<19>cm<-3> or less of impurity concentration.

Injection energy is so selected that the impurity boron 9 of the P-type diffused layer becomes a peak under a boundary between the silicide 6 and the silicon 1 to reduce a redistribution in the silicide and the silicon. The energy is so selected that the impurities As, P 8 of the N-type layer become peaks in or on a boundary between the silicide 6 and the silicon 1, and phosphorus, arsenic 8 are very rapidly diffused in the silicide 6. Thus, a preferable shallow junction can be formed.

Title: Trouble detecting circuit
Inventor: MORISUE HIDEO
IPC: G06F11/10
Filed: 1989-02-22
Abstract: PURPOSE:To detect the trouble of a multiplier only by performing the comparison between the estimating signal for the modulo-3 signal of the final result of multiplication and the correcting signal of the modulo-3 signal obtained by applying the addition of antilogarithm to the carry and the sum, i.e., the outputs of the multiplier. CONSTITUTION:When a carry is produced from the highest ran bit, 2 and 1 are added to a produced modulo-3 signal 38 if the final multiplication result 40 has the even and off bit widths respectively. Then a modulo-3 signal is pro duced again according to the result of correction and outputted as a correction circuit output 39 since >=3 produced modulo-3 signals way sometimes be obtained as the result of correction. Thus a coincidence detecting circuit 56 decides the coincidence or discordance between a pair of produced modulo-3 signals 37 and 39. As a result, the trouble of only a multiplier 50 is detected.

Abstract: PURPOSE:To improve workability in the manufacture of a double metallic tube and to facilitate the inspection of joined parts by reducing the projection of an extension external tube and repeating the joining of an extension internal tube, the expansion of tube, and the joining of the extension external tube. CONSTITUTION:When an internal tube 2 is expanded while the expansion of the diameter of its projected part 2a is controlled, most parts except the vicinity of the projected part 2a are closely adhered. In the state where the tip end of the internal tube 2 is joined with the extension internal tube, the projected part 2a of the internal tube 2 is not expanded in diameter, and consequently. a working space is secured in the case of joining the extension external tube to the external tube 1.

Title: Two-focus artificial lens
Inventor: KOIE KAZUTOSHI
IPC: G02B1/04
Filed: 1990-02-23
Abstract: PURPOSE:To prevent missing of the remote view function even when iris is contracted and provide easiness of fabricating by equipping a lens at least two radii of curvature on the front surface and rear surface. CONSTITUTION:The refraction power of a lens is determined by the radii of curvature on the front surface and rear surface. Therefore, the refraction power in No.1 zone 1 lying at the outermost edge is determined unambiguously by the radii of curvature on the front surface and rear surface. No.2 zone has a different refraction power than the No.1 zone 1 because the radius of curvature on the front surface is different from that of the No.1. Further, No.3 zone 3 has a different radius of curvature on the rear surface from the No.2 zone 2, so that the refraction power differs from the No.2 zone 2. Therein, the radius of curvature on the rear surface of No.3 zone 3 can be decided as any desired, ao that coincidence with the refraction power of the No.1 zone 1 is practicable. A two-focus artificial lens of the mentioned structure ensures that the remote view function is maintained even when the iris is contacted, and its fabrication is easy.
