Title: Heat exchanger
Inventor: KITANO SHINICHI
IPC: F24H9/00
Filed: 1996-10-14
Abstract: PROBLEM TO BE SOLVED: To improve the heating efficiency of a heat exchanger and lower the temperature of the combustion exhaust without increasing the passage resistance of the combustion exhaust by spreading a flow-straightening plate in the direction in which heat-exchanger tubes are arranged and a certain distance away from and above heat-collecting fins. SOLUTION: The combustion exhaust rises (Arrows A, B) toward an exhaust hood 18, threading through an arrangement of heat-exchanger tubes 15, but, with flow-straightening plates 21, 22 in its way, is prevented from flowing directly upward and guided to flow close to the upper half of the uppermost row of the heat-exchanger tubes 15. As a result, the quantity of heat which is transferred from the combustion exhaust to the heat-collecting fins 13 increases and, while the temperature of the combustion exhaust falls after passing the heat-collecting fins 13, the temperature of the heat-collecting fins 13 simultaneously rises, that is, the heating efficiency of the heat exchanger 10 improves.  Since the flowstraightening plates 21, 22 are placed a certain distance away from and above the cut-out parts 14 of the heat-collecting fins 13, the flow of the combustion exhaust is regulated without increasing its passage resistance or lowering the combustion efficiency.

Title: Multiplier
Inventor: SAKASHITA KAZUHIRO
IPC: G06F7/508
Filed: 1987-11-19
Abstract: PURPOSE:To realize an array structure suited to the high-speed arithmetic and also to an integrated form by securing such a constitution where the addition results of the unit circuit groups divided in response to the higher and lower rank digit partial product groups respectively are centralized. CONSTITUTION:The AND circuits 1a and 1b of the first stage of unit circuit groups 7 and 8 calculate each corresponding partial product respectively. The result of said calculations are given to the sum signal 5 to half adders 2a and 2b of the second stage respectively. The adders 2a and 2b add those signals 5 to each partial product and the results of these calculations are given to full adders 3a and 3b of the third stage as the signal 5 and the carry signal 6 respectively. Hereafter the calculation is carried out in the same way up to the final stage. Then both signals 5 and 6 obtained from each final stage are totalized every same digits via a unit circuit group 4. Thus the final result of multiplication is obtained. In such a constitution, it is possible to realize an array structure that has the natural signal transmission direction and is suited to an integrated form.

Title: Semiconductor device production method
Inventor: FUJIMOTO TAKATOSHI
IPC: H01L27/112
Filed: 1990-10-30
Abstract: PURPOSE:To reduce the space between polycrystalline silicon and reduce semiconductor device measurements by using an insulation layer and a high melting point metal as the mask material for ROM impurity ion implantation. CONSTITUTION:When forming a vertically stacked ROM. an oxide film 2 is formed on a silicon substrate 1, a polycrystalline silicon film 3 is formed on top of this, and finally a high melting point metal film 4 is formed. The polycrystalline silicon film 3 and the high melting point metal film 4 are simultaneously patterned and impurity ions are implanted to form a diffusion layer 5 in those areas not directly below the polycrystalline silicon 3 and the high melting point metal film 4. In the areas where the polycrystalline silicon 3 and the high melting point metal 4 are removed, an insulation layer 6 is grown, a photoresist 7 is formed over the entire surface, and patterning performed. After removing specific sections of the high melting point metal 4 by isotropic etching, the photoresist 7 is removed, impurities for ROM formation are implanted, and a diffusion layer 8 is formed directly below the polycrystalline silicon 3 only in areas where the high melting point metal 4 is removed. Since slight misalignments in the photoresist patterning do not have to be considered with this method, the space between the polycrystalline silicon can be reduced.
