Abstract: PURPOSE:To improve the repetitive life of recording and erasing by using the same material to form the base material of a mixed layer and the material of a protective layer. CONSTITUTION:This recording medium is made into the structure consisting in dispersing a recording material 4 into the base material 3 form the mixed layer and using the same material to form the base material of this mixed layer 2 and the protective layer 5. An abrupt change in the physical properties such as heat conductivity and coefft. of linear expansion at the boundary face between the mixed layer 2 and the protective layer 5 is eliminated and the local concn. of the stress arising from the repetition of recording and erasing is obviated, by which the repeating life of the recording and erasing is improved. The base material 3 is preferably materials which have the m.p. higher than the m.p. of the recording material and do not solutionize with the recording material, for example, dielectrics such as Al2O3, SiO2, GeO2, and WO3 and the combinations thereof. The recording material 4 is a chacogen compd. alloy, etc., consisting basically of Ge, Te, Se, etc. The protective layer 5 is formed of the same material as the material of the base material 3.

Inventor: UDAGAWA AKIHIRO
IPC: B05C11/10
Filed: 1997-04-08
Abstract: PROBLEM TO BE SOLVED: To provide an inexpensive float for detecting the content level in a vessel. SOLUTION: A float 68 is axially movably fitted in a syringe 62 containing an adhesive 60 and is floated on the adhesive 60. A float body 700 of the float 68 is a vessel-like integrally formed part made of nonmetal material, and on the bottom surface of an annular groove formed on the outer peripheral surface thereof, an aluminum layer 72 thinner than the depth of the annular groove is formed. On the other hand, a level detector 100 equipped with a high frequency oscillation type contactless switch is provided near to the outer peripheral surface of the syringe 62. The adhesive is discharged by fixed quantities by feeding compressed air at fixed time intervals to apply it in spots on a printed circuit board.  When a float 68 descends with a decrease in the adhesive 60 and the aluminum layer 72 is made in an opposite state to the high frequency oscillator, the level detector 100 detects it and informs a worker that the adhesive 60 has been reduced.

Title: Developer
Inventor: HIRONO TAKEO
IPC: G03G9/08
Filed: 1984-04-27
Abstract: PURPOSE:To enable cleaning without using electrostatic attraction and development with sufficient density by using a binary developer mixing a specified magnetic toner in a system using a device for executing both of developing and cleaning functions. CONSTITUTION:The developer is a binary mixture of a magnetic carrier and the magnetic toner, and an electrostatic charge controller is added to the toner so as to control a charge of toner to be triboelectrified with the carrier to <=+ or -8muC/g in the case of a magnetic material of >=45wt% of the magnetic toner. When a triboelectrified charge of the toner exceeds 8muC/g in the same polarity as that of a photosensitive body, the repulsion force between the electrostatic latent image and the triboelectrified toner charge is stronger than the electrostatic attraction force between the latent image and the toner, resulting in disabling development. When it exceed 8muC/g and it is reverse in polarity, the attraction force between the photosensitive body and the toner is very strong, and the body cannot be cleaned only by rubbing force and magnetic force, and an image is deteriorated in quality.

Filed: 1983-05-24
Abstract: PURPOSE:To obtain the format of an image of invariably high quality regardless of variation in the electrostatic charging amount of toner with environment by holding the layer thickness specifying member for a sleeve with float electrodes electrically insulated. CONSTITUTION:A blade 12 as the layer thickness specifying member is arranged at the downstream side of a toner hopper 11 in the rotation direction of the sleeve 8 with float electrodes. Then the blade 12 is held electrically insulated through an insulating layer 12b without being grounded through a housing, etc., and a change which is generated by frictional electrostatic charging to the polarity opposite to that of toner 10 is held in the blade 1. Therefore, if the electrostatic charging amount of the toner 10 increases owing to a decrease in humidity, etc., the electrostatic charging amount of the blade 12 also increases and the charge is neutralized by discharging when both leave each other to suppress the electrostatic charging amount. Consequently, an image of invariably high quality is obtained regardless of electrostatic charging condition such as environmental variation.

Title: Fibrinolytic agent
Inventor: SAKAI MASASHI
IPC: A61P7/02
Filed: 1988-04-14
Abstract: PURPOSE:To obtain a fibrinolytic agent which is used for treating cardiac infarction, cerebral infarction, arteriosclerosis or the like by using staphylokinase which selectively dissolves fibrin with high stability kept in living bodies. CONSTITUTION:The subject fibrinolytic agent contains staphylokinase, as an active ingredient, which as high specificity to fibrin and high impregnation into thrombus, because its molecular weight is small, namely about 15,000. Staphylokinase forms a complex with plasminogen, and the complex resists to the inhibition by alpha2-plasmin inhibitor, thus the decomposition of the thrombus (in other words, dissolution of thrombus) proceeds selectively. Further, it has excellent stability in blood to keep its activity in living body for a long time, resulting in enhancement of fibrinolysis in blood. It suggest that this agent may be efficacious for chronic thrombosis.
