Title: Controlling device for pwm inverter
Inventor: ASAKAWA YUKIO
IPC: H02M7/48
Filed: 1985-09-26
Abstract: PURPOSE:To prevent magnetic saturation of a load of DC state by connecting the primary side of a CT in series between a plurality of pairs of current switching elements connected between the positive and negative sides of a DC power source, and connecting its neutral point with an AC load. CONSTITUTION:A DC power source 1 is supplied three pairs of current switching elements (2, 3) (4, 5) (6, 7) to generate 3-phase ACs to be supplied to a load 8. CT10U, 10W are provided in U and W phases, the primary side of CT is connected in series with current switching elements 2, 3 and 6, 7, its neutral point and V phase are connected with an AC load 8, and currents i1U-i1W are fed. Positive and negative alternating currents flow to both sides of the primary side neutral point of the CT by load and circulating currents. However, since the secondary side currents i2U, i2W of the CT are not similar to the i1U, i1W, their polarities are discriminated by discriminators 11U, 11W, current values are calculated by current calculators 12U, 12W, to become similar. Thus, even if the load current becomes a DC state, the CT is not magnetically saturated, but an inexpensive PWM inverter can be manufactured.

Title: Hologram exposure device
Inventor: BABA NOBUYUKI
IPC: G03H1/04
Filed: 1986-09-10
Abstract: PURPOSE:To adjust two pieces of luminous flux to equal optical path length by providing a liquid cylinder which transmits laser light on the optical path of at least one of the two pieces of luminous flux. CONSTITUTION:When the two pieces of luminous flux are not equal in optical path length, the liquid cylinder 20 is placed on the optical path of one of the two pieces of luminous flux which are split by a beam splitter 2 and shorter in optical path length, i.e. at a position 32 or 34. When liquid cylinders are arranged on the optical paths, this is not required. Here, how much the optical path length needs to be increased to equalize the two pieces of luminous flux in optical path length is predicted from the distribution of diffraction efficiency to nm order, so how long distance S is in concrete is calculated from the refractive indexes of the liquid in the cylinder and transparent windows 22 and 26, and a piston 24 is moved by a specific quantity in a specific direction based upon the calculation result to perform exposure again, thereby confirming the coincidence. Consequently, the two pieces of luminous flux are equalized in optical path length almost by single-time adjustment.

Abstract: PURPOSE:To provide high efficiency and reliability by improving the degree of power generation efficiency drop due to the improper seal of fuel and oxygen gases, and the degree of thermal strain due to a crossing type cell module in the conventional structure of a flat type solid electrolyte fuel cell. CONSTITUTION:An oxygen electrode 1 is made of a bottomed rectangular parallelopiped having many holes, and the film of a solid electrolyte 2 as a film resistant against gas permeation is formed on one side of the parellelopiped. The other side thereof is covered with the film of an interconnector 4 as a film against gas permeation as well, thereby forming a single cell 5. With the application of this construction, a mixing process is prevented from taking place between oxygen gas supplied to the inside of the electrode 1, and fuel gas supplied to the outside of the bottomed parellelopiped, without any sealing treatment. A drop in power generation efficiency is thereby prevented. Also, oxygen gas feed tubes 7 are inserted in the upper opening sections 6 of the holes, and an identical flow direction is maintained for oxygen gas on the electrode 1 and fuel gas on a fuel electrode 3 formed on the solid electrolyte 2. As a result, thermal strain distribution over a cell power generation section is made uniform and thermal strain is restrained, thereby improving the reliability of a battery.
