Title: Filter, auxiliary light source and light ray medical treatment device
Inventor: MORIKI AKIO
IPC: A61N5/06
Filed: 1990-07-20
Abstract: PURPOSE:To diagnose the condition of a patient without causing great difference in color tone between light from a light ray medical treatment device and environmental light by providing the light ray medical treatment device with a filter and an auxiliary light source. CONSTITUTION:When a filter is used light for treatments is absorbed by the filter so that the light transmitted through the filter becomes white or such one that provides almost the same light stimulus as that caused by illumination using environmental light. When an auxiliary light source is used, light with colors complementary to the light for treatments or environmental light with complementary colors is generated and so illumination toward a child approximates one with white light or light from an environmental light source and an observer of the child receives almost the same color stimulus as that caused by white light or environmental light, as is the case when using the filter. The use of the light ray medical treatment device thus makes it possible for the observer to properly diagnose the condition of the child, with the colors of the face and skin of the child almost the same as while under environmental light.

Title: Magnetic disk device
Inventor: TAGAWA NORIO
IPC: G11B21/21
Filed: 1990-07-19
Abstract: PURPOSE:To realize the magnetic disk device, for which a head fitting margin is enlarged, to be easily manufactured and assembled by suitably setting the initial set posture of a negative pressure floating head slider based on the result of simulation. CONSTITUTION:When initially setting and fitting a negative pressure floating head slider 1 onto a magnetic disk medium 2 with noncontact, an angle theta1 is set within 2 deg. and an angle theta2 is set within 0.2 deg.. In this case, the angle theta1 is an angle in a direction where the air flowing-in terminal interval amount of the negative pressure floating head slider 1 is made smaller than an air flowing-out terminal interval amount, and the angle theta2 is reverse, namely, an angle in a direction where the air flowing-in terminal interval amount of the negative pressure floating head slider 1 is made larger than the air flowing-out terminal interval amount. Thus, the device can be easily assembled with an allowable range extremely larger than conventional one. Further, even in the self loading of the negative pressure head slider, the slider does not come into contact with the disk, and the reliability is also improved equally to the conventional case. When manufacturing and assembling the magnetic disk device, the head fitting margin can be enlarged equivalently.

IPC: F03B17/02
Filed: 1987-07-30
Abstract: PURPOSE:To take out power from the head of liquid by attaching liquid containers to both ends of an oscillating unit and connecting the liquid containers to liquid vessels through pipes. CONSTITUTION:Liquid containers 1, 2, 3, 4 are attached to both ends of an oscillating unit 5. The liquid containers 1, 4 are respectively connected to liquid vessels 6, 7 through pipes 8, 9. When the left of the oscillating unit is pushed up, the liquid container 2 sinks in the liquid of the liquid vessel 6 and the liquid container 1 is lowered at the same time so that the liquid in the liquid vessel 6 flows through the pipe 8, and thereby the container 1 becomes heavier. On the other hand, the buoyancy of the container 3 is reduced and the liquid in the container 4 flows out, and thereby the container 4 becomes lighter. With this arrangement, the oscillating unit 5 is balanced so that power can be taken out from the height difference between the liquid in the liquid vessels 6 and 7 through an arm 11 by a power detecting unit 10.
