Title: Method for automatically expanding control range of resonant converter of frequency control
Inventor: YUGAWA TAKASHI
IPC: H02M3/335
Filed: 1997-09-30
Abstract: PROBLEM TO BE SOLVED: To perform control from unloaded state, by connecting a parallel capacitor to a secondary side and applying parallel resonance on light loading. SOLUTION: In a converter, an output voltage Vo is divided by a resistor, it is compared with a built-in reference voltage by a comparator C1, and the error voltage Ver is fed back to a primary side via a photocoupler PC1. The error voltage Ver becomes low and an oscillation frequency becomes high in the case of a light load. On the other hand, in the case of a heavy load, the error voltage Ver becomes high and the oscillation frequency becomes low. Therefore, when a parallel capacitor Cp is installed and removed, an input voltage Vin is set to an upper limit DC 380 V with the narrowest control range, the load at a secondary side is gradually reduced from the maximum for stopping immediately before control cannot be made, the error voltage is set to a comparator IC2.  Then, the error voltage is compared with an error voltage that actually changes, the comparator IC2 is turned on and off, and a triac Tri is switched, thus connecting a capacitor Cp to a secondary coil, applying parallel resonance, and hence enabling control from an unloaded state.

Abstract: PURPOSE:To seal sealing surfaces in noncontact state by forming a spiral groove in a mirror image relation on both the sealing surfaces of a rotary ring and a nonrotary ring and sending the sealing fluid between both the sealing surfaces under pressure for the revolution in the normal and reverse directions. CONSTITUTION:A rotary ring 3 which is sealing-fixed on a rotary shaft 2 and a nonrotary ring 4 which is sealing-installed on a housing 1 have sealing surfaces 5 and 6, respectively. On the sealing surface 5, a number of spiral grooves 8 which extend inward from the outer peripheral edge of the sealing surface 5 and have each advance angle for the revolution direction are formed in the circumferential direction. While, on the sealing surface 6, a spiral groove 9 which has a sweep-back angle for the revolution direction is formed so that a nearly mirror image relation is generated for the spiral groove 8. With this constitution, a fluid transport force is generated by the spiral groove 8 formed on the sealing surface 5 in case of the normal direction revolution, while by the spiral groove 9 on the sealing surface 6 in case of the revolution in the reverse direction. Accordingly, the sealing fluid is sent under pressure between both sealing surfaces 5 and 6, which are sealed in noncontact state.

Abstract: PURPOSE:To improve the throughput of the production of a semiconductor integrated circuit and to reduce the cost thereof by subjecting a photomask for projection made of quartz having the same outside diameter and thickness as the outside diameter and thickness of a wafer to direct plotting by using an electron beam exposing device. CONSTITUTION:Fine patterns can be exposed as they are and inexpensively and speedy to the substrate of a glass mask 2 if the shape, thickness and surface flatness of the glass mask 2 to be used including the tolerance thereof are set the same as the standard specifications specified to the wafer 1 by utilizing the electron beam exposing device which executes the direct plotting on the water 1. The glass mask 2 is formed to the same outside diameter (phiM), thickness (tM) and tolerance as the outside diameter (phiM), thickness (tM) and tolerance of the wafer 1. However there is no need for an orientation flat 3 which exists in the wafer 1. Namely, the glass mask 2 has the same outside diameter and thickness as the outside diameter and thickness of the wafer 1 and since the glass mask 2 is the photomask for projection made of the quartz, the procedures for producing the mask are shortened and the stages are curtailed.
