Patent JP-H02254754-A (JP)
Title: Semiconductor device
Inventor: MAEDA MITSUHIDE
IPC: H01L29/80
Filed: 1989-03-28
Abstract: PURPOSE:To facilitate the manufacture of electrodes and to make it possible to reduce sufficiently an electrode resistance by a method wherein the thicknesses of the stem parts of the electrodes are made thicker than the thicknesses of the branch parts of the electrodes. CONSTITUTION:A cathode electrode 13 and a gate electrode 16, which are formed on the surface of a semiconductor substrate 2, respectively consist of stem parts 13' and 16' and a multitude of branch parts 13'' and 16'' which are extended from the stem parts 13' and 16' in a comb-teeth form. In these electrodes 13 and 16, the stem parts 13' and 16' are both formed wider in steps as they go from their points toward their joints. Moreover, in the electrode 13 and the electrode 16, two Al layers are laminated at the stem parts, but one layer of an Al layer simply exists at the branch parts. In such a way, as the thicknesses of the stem parts, on which a current is concentrated, of the element electrodes are thicker than the thicknesses of their branch parts, a work of the branch parts does not become a difficult task and an electrode resistance can be reduced.

Title: Fuel assembly
Inventor: TERASAKA HARUO
IPC: G21C3/34
Filed: 1988-03-31
Abstract: PURPOSE:To plan the reduction of pressure loss of the upper part of a fuel assembly by widening the interval of a spacer above the point, at which two- phase coolant makes the transition to ring flow, more than the spacer interval therebelow. CONSTITUTION:For example, one of spacers 6 heretofore is lowered at a position lower than the upper end of an effective fuel range (heat generating range) 2a of a fuel rod 2 while the intervals between an upper tie plate 4 and the spacer 6 and between the spacers 6 are arranged 1.2-1.3 times wider than the conventional spacers. At the lower position where support force of the fuel rod 2 is required, the support force is held by the spacer intervals as while the pressure loss by the spacers 6 is reduced. Therefore, the efficiency of a reactor can be improved.

IPC: F04B9/00
Filed: 1978-06-27
Abstract: PURPOSE: To dispense with a mechanical driver, simplify the construction of a pump and facilitate its output control, by utilizing the emission pressure of ultrasonic waves to cause a pumping action.  
     CONSTITUTION: The ultrasonic waves 10 are emitted from an ultrasonic oscillator 9 to an outlet port 6 through a container 1 filled with a fluid 2. The ultrasonic waves introduced into an incidence port 12a are reflected on the inside surface of an ultrasonic reflector 12 and converged to an output port 12b because of the directivity of the waves. As a result, a strong acoustic field is generated by the ultrasonic waves in the output port 12b and the emission pressure proportional to the intensity of the acoustic field is caused. The fluid 2 is driven by the emission pressure and discharged from the outlet port 6. Side pressure oriented from a zone without the ultrasonic waves 10 to another zone with the waves is caused. The fluid 2 flows into the container 1 through an inlet port 5.
