Title: Light source-integrated contact lens electrode
Inventor: MOTOKAWA AKIRA
IPC: A61B5/04
Filed: 1994-12-01
Abstract: PURPOSE: To properly inspect a visual cell of a rod system by arranging plural light sources having the respectively different monochromatic light in a light source holding body, and generating the monochromatic light and the white light as the stimulating light for electroretinography in a light source integrated contact lens electrode to be used in an electroretinographic device of an eyeball. CONSTITUTION: Cylindrical recessed parts 8a to 8c are arranged in their slant posture on a rear end surface of a light source holding member 12 so that the respective axes A to C coincide with a convex lens 7, and semiconductor light emitting elements, for example, light emitting diodes 9a to 9c to respectively generate the light of red, green and blue are fitted and fixed to the respective recessed parts 8a to 8c. When an electric current is carried to the light emitting diodes 9a to 9c, the emitted respective monochromatic light pass through a horny coat joining part 1 mixed and diffused by the convex lens 7, and is made incident in an eyeball 13. Since the optical axes A to C are adjustably arranged on a central point P of a rear end surface of the covex lens 7, the whole area of the retina 13' is uniformly irradiated by the white light.  A change in retinal electric potential generated thereby is taken out by a ring-shaped electrode 4, and is recorded by an electroretinographic device.

Title: Logic circuit
Inventor: TAKI YOICHIRO
IPC: H03K19/088
Filed: 1986-12-15
Abstract: PURPOSE:To always keep the output at a high impedance even when a high potential power source is switched to the turning-on state at the time of control to the high impedance output, by connecting the base of a fourth transistor TR to the high potential power source through a series connection body of a resistance and two forward diodes. CONSTITUTION:Two Schottky barrier diodes SBDs are inserted in series to a resistance 28, which connects the base of the fourth TR 18 to a high potential power source 1, in the forward direction. The operation in the steady state where the high potential power source 1 is turned on is equal to that of a conventional circuit; but if the high potential power source 1 is switched from the turning-off state to the turning on state on a set condition that a signal of the high level is applied to an output control input 3 and an internal signal 29 goes to the high level, the voltage of the high potential power source 1 with which fourth and fifth TRs 18 and 19 can be made conductive is about 2.5V because of addition of SBDs 33 and 34 and is higher than about 2.25V for first-third TRs 5-7. Thus, fourth and fifth TRs 18 and 19 are not made conductive when the high potential power source 1 is switched from the turning-off state to the turning-on state, and the output terminal 3 keeps the high impedance.

Title: Positioning device
Inventor: MASUKO KAZUYA

Filed: 1990-11-02
Abstract: PURPOSE:To position at the same absolute point even with the displacement of the positioning operation limit by feedback-controlling a drive means so that the actual position of a driven body agrees to the target position calculated with an arithmetic means. CONSTITUTION:In the case of playing back of a running part 4 to a determined target position Q, a target position calculation part 22 reads each of pulse value P2 of a reference position B from a reference position memory part 17 and a pulse count P3 of an operation command D from a differential value memory part 18 and adding all these values to calculate the pulse value q of the target position Q. Then a calculation part 23 judges whether or not the running part 4 has reached the target position Q. If the running part 4 has not reached the target position Q, processing goes back to the original step. In this manner, the feed back control is executed until it agrees with the output pulse value q of an encoder 8.

Title: Signal reproducing method of optical recording medium
Inventor: FUKUMOTO ATSUSHI
IPC: G11B11/105
Filed: 1991-10-19
Abstract: PURPOSE:To enhance a recording capacity of a medium by reducing a cross talk from an adjacent track and making narrow a track pitch by using a semiconductor laser as a laser beam source and making the minor axis direction of a spot form of exit light from the semiconductor to the direction being orthogonally crossed to the laser scanning direction. CONSTITUTION:A spot form of laser beams emitted from an active layer 22 of the semiconductor laser 21 forms an ellipse form being the direction parallel to the layer as the minor axis and being the depth direction of the layer as the major axis. The minor axis b direction of an ellipse form of a spot SP on the optical recording medium of the exit light from the laser 21 is made the direction being orthogonally crossed to the laser scanning direction. Hence the intensity of laser light radiating a record bit of the adjacent track is decreased, so the transfer of the signal being recorded and held at the adjacent track position is reduced for example in a magneto-optical recording medium of an erase type or an erase and raise mixing type, the cross talk is eliminated and the density is high since the track pitch is close.
