IPC: A61F9/01
Filed: 1990-05-23
Abstract: PURPOSE: To reconstruct the eye cornea to correct visual power fall by removing specific amount of the cornea tissue and smoothening its surface by laser ablation. CONSTITUTION: Eye cornea 18 is composed of an upper skin 20, Bowman's membrane 22, cornea substrate 24, Descemet's membrane 26 and cornea inner skin 28. Reconstruction of the cornea is made through two-stage laser ablation operation. As the amount of removed cornea tissue is specified, comparably larger part of the amount is removed by the laser ablation at the first stage. At this stage to comparably quickly remove selected parts of the upper skin tissue 18, Bowman's membrane 22 and cornea substrate 24, it is preferably to apply the laser of 0.527 micron wavelength. It is required to smooth corrected surface 38 of the reconstructed cornea 18 after the tissue is removed as there appear projections 40 and hollows 42 on it. At this stage of smoothening, it is required to apply the laser pulse to laser-ablate tissue of the cornea substrate 24 to the depth of 1 micron or less. This second stage is implemented through scanning the whole corrected surface with the laser of 2.94 micron wavelength.

Title: Throttle control system for internal-combustion engine with automatic transmission gear
Inventor: URIYUUBARA MAKOTO
IPC: B60W10/02
Filed: 1984-06-26
Abstract: PURPOSE:To prevent racing of an engine during disengagement of a clutch, by a method wherein, in case a clutch is disengaged in a state of no transmission operation being effected, disengaging operation is controlled through comparison of the current optimum opening of a throttle valve with the detecting opening of the throttle valve, the set opening of the throttle valve is corrected and controlled. CONSTITUTION:When, with the aid of an electronic control device 13, turning ON of an idle switch 17 detects that an accel pedal 14 is released from step-on of a foot during operation of a vehicle, it is decided whether a next car speed detected by a car speed sensor 10 is equal to or becomes below a set car speed V0 stored in a ROM13a. When the decision is YES, an optimum throttle valve opening TH1 at which a clutch 2 is disengaged in response to an output from a rotary sensor 8 is read, and the opening is compared with a present throttle valve opening TH provided by a throttle valve opening sensor 18. In the case of TH<= TH1, a clutch actuator 3 is controlled so that the clutch 2 is started to be disengaged. Thereafter, the set throttle valve opening is corrected and controlled to an optimum time responding to a clutch stroke.

IPC: G01N27/82
Filed: 1989-05-26
Abstract: PURPOSE:To allow the detection of the defect in a ferromagnetic material by using a Barkhausen effect by detecting the Barkhausen signal when current falls. CONSTITUTION:The DC current is applied to an exciting electromagnet 5 by a trapezoidal wave generator 14 and a DC power source device 15 controlled by a computer 13 to generate a magnetic field in the sample 2. The Barkhausen signal by the Barkhausen effect is detected by a signal detector at the time of the rise and fall of the current at this time. The detected signal is amplified in a preamplifier 7, is passed through a high-pass filter 8 and is amplified in a main amplifier 9. Since the Barkhausen signal is an impulsive signal, the number of the pulse signals per unit time is counted by a counter 10 and is converted to an analog signal by a D/A converter 11. The analog signal is taken together with the signal from the device 15 into an A/D converter 12 and is sent to the computer 13 as the information to elucidate the correlativeness between the current change and the time when the signal is generated to the computer 13 where the information is processed.
