Inventor: HORIGUCHI AKIO
IPC: G11B5/02
Filed: 1988-08-01
Abstract: PURPOSE:To execute a speed-up at the time of writing data by lining a first pick-up head exclusive-use for erasing and a second pick-up head for writing and reading data on the same track and installing external magnetic field magnets for auxiliary magnetic fields in upper positions corresponding to respective heads in fixing N and S poles. CONSTITUTION:At the time of writing the data, the combination of the first pick-up head 11 exclusive-use for erasing and a first external magnetic field magnet 13 and the combination of the second pick-up head 12 exclusive-use for writing and reading and a second external magnetic field magnet 14 are installed on the same track.

Title: Ophthalmologic apparatus
Inventor: KOBAYAKAWA YOSHI
IPC: G02B21/18
Filed: 1992-06-26
Abstract: PURPOSE:To provide the ophthalmologic apparatus which is simple in construction and can make wide-angle photography with a high resolving power by using a rotary reflection member to project a slit-luminous flux to the fundus oculi and using a line sensor array to obtain a two-dimensional fundus oculi image. CONSTITUTION:The luminous flux is made into slit light by a slit 2 when a white light source 1 is lighted at the time of image pickup. The fundus oculi Er of the eye E to be examined is illuminated with the slit light through a lens 4, a focusing lens 5, a relay lens 7, a galvanomirror 8 and an objective lens 9. The illuminating light is the slit light but is deflected and scanned by the galvanomirror and the fundus oculi Er is therefore two-dimensionally illuminated. The light reflected from the fundus oculi returns the same optical path, is reflected by a half mirror 6, is reflected by a moving mirror 11 through the focusing lens 10 and is made incident on the line sensor array 12. The conjugation relation with the fundus oculi Er is maintained by moving the focusing lenses 5, 10 at this time. The outputs from the line sensor array 12 are integrated to video signals by a signal processing control circuit 14 and the black and white fundus oculi image Er' is displayed on a television monitor 15.

Abstract: PURPOSE:To obtain the resin seal type semiconductor device having excellent reliability regarding dampproof property, high-temperature electric characteristics, etc. by using a hargener manufactured by combining polyoxystyrene and novolac type phenol resin and an epoxy resin composition employing an organic phosphine hardening accelerating agent as sealing resin. CONSTITUTION:The composition consisting of the novolac type epoxy resin of 170-300 epoxy equivalent, polyoxystyrene, novolac type phenol resin and an organic phosphine compound is used as the composition for sealing.

It is preferable that the compounding ratio of novolac type phenol resin is within the range of 0.01-100wt.pt. novolac type phenol resin to 1wt. polyoxystyrene. The quantity of the organic phosphine compound compounded may generally be within the range of 0.001-20wt% of resin components (the total amount of epoxy resin and the hardener), but the epoxy resin composition having excellent dampproof property and superior curing characteristics can be obtained especially when the quantity is brought within the range of 0.01- 5wt%.

Title: Dry-type multi-layered analytical element
Inventor: ARAI FUMITADA
IPC: C12Q1/26
Filed: 1986-08-19
Abstract: PURPOSE:To speed up oxidation reaction and to prevent the fading of chromogeN by forming a hydrogen peroxide decomposing enzyme-contg. layer and chromogen-contg. layer to different layers and disposing said enzyme-contg. layer to the layer further from a base than the chromogen-contg. layer. CONSTITUTION:Serum is oxidized by the cholesterol oxidase existing in the hydrogen peroxide decomposing enzyme-contg. reagent development layer 52 disposed on the uppermost layer to form H2O2 when the serum contg. cholesterol is spotted onto the development layer 52. This H2O2 oxidizes a ferrocyan ion to form a ferricyan ion. The formed ferricyan ion arrives at the chromogen layer 20 formed on the base 10 and oxidizes the chromogen to the chromatic dye proportional to the amt. of the cholesterol. The supply of the enzyme necessary for the reaction is facilitated by placing the development layer 52 to the uppermost layer in the above-mentioned manner; therefore, the progression speed of the oxidation reaction is increased. Since the chromogen is separated from an H2O2 reaction part, the fading of the chromogen by contacting the H2O2 is prevented.
