IPC: A61B17/32
Filed: 1995-06-14
Abstract: PURPOSE: To remove an epithelial layer easily, exactly, cleanly and effectively before an operation by forming an abrasive surface to be fitted with projecting bending of the cornea, bringing the abrasive surface into contact with the cornea slightly, rotating the abrasive surface to divide the epithelial layer of the cornea into small removable cell chips and emulsify them. CONSTITUTION: An irregularly cut member 1 has many solid bundled bristles 4 extended from a base 3. The bristles consist of adjacent parallel slender filaments. The bristles 4 are constrained each other, arranged in a row line and supported by an outer ring 5 in the bundled state. The outer ring 5 can be controlled at a position along the longitudinal direction of the bristles. Thereby, hardness of a bristle part 4a and a free surface of the bristles extended across the outer ring 5 are controlled. The brush of the irregularly cut member 1 is fitted with an upper end of a motor handle 2 and kept above an eye 13 of a patient. Then, a motor button 2' is operated to rotate the brush 1, thereby all epithelial cells are divided into very small chips, emulsified, if necessary, removed off fine chips and/or washed.

Title: Logic circuit
Inventor: SHODA HIROAKI
IPC: H03K19/018
Filed: 1990-06-06
Abstract: PURPOSE:To attain a high-speed operation by discharging the output of an emitter follower circuit synchronously with the latch timing of an output latch circuit. CONSTITUTION:When a clock phi falls down, in response to this timing, an F/F 4 for input latch latches an input data and the data is directly inputted to an emitter follower circuit 1 so as to get a level corresponding to the level of this latch data at the output of the emitter follower circuit 1. When the inverse of the clock phi falls down from a high level to a low level, in response to such a state, the output of a combining circuit 2 is fetched to an F/F 3 for output latch and since the clock phi is transited from the low level to the high level simultaneously, a transistor 5 is turned on to clamp the base potential of the emitter follower circuit 1 to a ground potential. Thus, since a discharging period is provided without fail between a certain enable period and the next enable period, high-speed load driving is enabled.
