Title: Device for removing diseased part in eyeball
Inventor: ASAMI HIRONOBU
IPC: A61F9/00
Filed: 1988-09-03
Abstract: PURPOSE:To condense laser beam to a diseased part, to irradiate a diseased part with the laser beam and to cut, crush or emulsify the diseased part by attaching a concave mirror, which reflects the laser beam, to the tip part of a tube, which forms a sucking route or an irrigating route, changing the direction of the laser beam, reflecting and condensing the laser beam with this concave mirror. CONSTITUTION:In a tube 1 having a sucking route 1a which sucks the diseased part in an eyeball with negative pressure, plural optical fibers 2 are linearly arranged to irradiate the diseased part with the laser beam. The optical fiber 2 is directly arranged in the sucking route 1a, however, it can be also arranged in a route, which is separated from the sucking route 1a on space by partitioning the sucking route 1a with a partition wall. Since the tip surface of the optical fiber 2 is not spherically formed, the laser beam is not condensed but emitted forward. IN the front of the optical fiber 2 tip, a concave mirror 3 is attached to the tip of the sucking tube 1. Since this concave mirror 3 has a bent reflecting surface, especially has a cylinder-shaped reflecting surface, the reflected laser beam is condensed at a focus 4. The condensed laser beam cuts, crushes or emulsify the diseased part.

Title: Golf cart
Inventor: SAKAO KAZUHIRO
IPC: A63B55/60
Filed: 1988-09-05
Abstract: PURPOSE:To protect the circuitry and a motor by detecting the armature current based on the voltage droop across the series winding of a motor and increasing the duty continuously when the magnitude of the armature current exceeds over a specific value thereby varying the magnitude of the distributed winding current and making control such that the magnitude of the armature current does not exceed over the specific value. CONSTITUTION:When the load increases with maximum accelerator opening, armature current Ia starts to exceed over a maximum allowable value I1. At this time, an armature current detecting circuit 6 detects a current corresponding to the voltage produced across a series winding 3b and provides a signal to a duty control circuit 5. Consequently, control is made such that the duty is increased in spite of the reception of the signal fed from an accelerator opening detecting circuit 7 thus increasing the distributed winding current Ib and providing armature current I1 with lowered rotation. By such arrangement, overheat of the motor or overcurrent in the circuitry can be prevented independent of accelerator operation.

Filed: 1989-08-29
Abstract: PURPOSE:To effectively prevent and inhibit the transverse swing of shoes when the sole of shoes touch ground by mounting respectively at the external fringe of the heel portion of the sole and the external fringe of insole rubber-made stabilizers the lower face of which is externally protruded and the bottom of which touches ground. CONSTITUTION:Stabilizers 5 and 6 formed of rubber with the JIS-hardness of 60 degrees respectively on the external fringe of the heel portion of the sole 2 of the shoes bottom 1 and on the external fringe of the intermediate portion. The occurrence of swing in the transverse direction and excess outward turn when the shoe bottom 1 touches ground is prevented by providing stabilizers 5, 6 the lower part of which are protruded to the outside. In this case, the effect can be secured by permitting the lower plane of the external fringe to get protruded to the outside. In other words, when the shoe bottom touches ground in the foot work the external fringe of the heel portion of the shoe sole first touches ground. The swing in the transverse direction and excess outward turn can be more surely inhibited by making the external fringe of the lower face of the stabilizer 5 at this point protruded to make the portion to touch ground.
