IPC: F03B15/04
Filed: 1982-06-18
Abstract: PURPOSE:To obtain small size and simplification of a control mechanism of a bottom stage guide vane, by fixing an opening of the bottom stage guide vane to a lower limit opening in a position below a lower limit in a normal operation range. CONSTITUTION:If upper and bottom stage guide vanes are synchronized and load regulation is assumed to be performed, an efficiency characteristic as shown by a curve D in the drawing, and equivalent to that of a single stage pump water turbine is obtained.

Abstract: PURPOSE:To leave resist as thick as desired on the center of a semiconductor substrate and prevent a crown from being produced on the periphery by applying light, which has energy to thin the resist of crowns on the periphery of the substrate by the desired thickness when developed, only to the periphery of the substrate. CONSTITUTION:When resist 2 is applied to a semiconductor substrate 1, crowns 3 are made of the resist 2 on the periphery 1a of the semiconductor substrate 1. A glass mask 4 having a pattern 4a capable of exposing only the periphery 1a of the semiconductor substrate 1 having the crowns 3 to light is arranged on the semiconductor substrate 1. When light 5, which has energy to halve the thickness of the resist 2 of the crowns 3 when the semiconductor substrate 1 is developed, is applied to the semiconductor substrate 1 through the glass mask 4 and then the semiconductor substrate 1 is soaked in a developer or an organic solvent, the resist 2 is developed.

Title: Buffer memory
Inventor: OUCHI NOBUAKI
IPC: H04L7/02
Filed: 1985-05-17
Abstract: PURPOSE:To attain the detection of consecutive zeros without causing mis- conversion by providing two memories to the pre-stage of a multiplex circuit in a buffer memory converting '0' into '1' for preventing consecutive zeros. CONSTITUTION:A data Dn is generated by an information generation circuit 11, stored in memories 13, 14 at first and a consecutive-zero detection circuit 15 detects consecutive zeros at the same time. When no consecutive zero is detected, the data Dn in the memory 14 is sent directly. When the circuit 11 generates a data Dn+1 next, the data is written in both the memories and if consecutive zero is detected, a clock to the circuit 11 is stopped and a selector 12 is thrown to the position of the memory 13. The circuit 15 sends a read signal to the memory 14 to send only a data D'n+1 except a part X overflowed by the insertion of '1' to a multiplex circuit 16. The circuit 16 inserts '1' to the data D'n+1 and sends the result. The memory 13, the same as the memory 14, reads only the frame X overflowed and inputs the result to the selector 12. Thus, the said X is added to new data Dn+2 of both the memories and used for the detection of consecutive zero.
