Title: Manufacture of sound steel ingot and mold to be used for said purpose
Inventor: KAWAKAMI KIMINARI
IPC: B22D11/00
Filed: 1980-07-21
Abstract: PURPOSE: To manufacture sound steel ingots having no microsegregation, by preventing the surfacing of molten steel by flowing the molten steel in the solid-liquid coexisting area toward the lower part of mold by an electromagnetic force when steel ingots are solidified.  
     CONSTITUTION: A mold 5 is made of cast iron for the section 20W80% from the bottom and the remaining upper section is constituted of refractories 6 having a shell 7 with 10W50mm thick stainless steel. The molten metal is charged into the mold 5 and an electric current is supplied to an electromagnetic stirring coil 9. The electric current is increased as the solidification of molten metal progresses. When the electric current is increased, the elctromagnetic force is also increased. This power supply is continued until a steel ingot solidifies completely. Since the value of electric current is set so that the flow speed of downward flow of the molten metal between the front end position of crystallized steel (a) and the position of completely solidified steel is regulated to approx. 5cm/min and the surfacing of molten steel in the inverted V shaped segregation area is prevented, it must be determined by considering the quality of the shell 7, the solidified amount, the thickness of refractories 6, the structure of electromagnetic stirring coil 9, the specification of power source, etc.

Title: Electrophotographic sensitive body
Inventor: YAGI SHIGERU
IPC: G03G5/147
Filed: 1983-06-03
Abstract: PURPOSE:To obtain an electrophotographic sensitive material which has a protective layer dispersed with pulverous metallic oxide layer in a binder resin as a surface layer and which is hardly affected by temp. and humidity without accumulation of residual charge even after repetitive use by coating the surface of the pulverous metallic oxide powder with tin oxide and/or antimony oxide. CONSTITUTION:Conductivity can be improved even if pulverous metallic oxide powder particles having not so much high conductivity are used in order to cover the surface of the pulverous metallic oxide powder particles with a material having relatively high conductivity such as tin oxide or antimony oxide. The tin oxide or the antimony oxide is white and does not absorb visible light and therefore the transparency of the protective layer can be maintained in spite of the light absorptivity of the metallic oxide to be used as an essentially material. The average grain size can be made 0.3mum by using the tin oxide or antimony oxide having relatively high conductivity and therefore the transparency of the protective layer is much higher. Since the protective layer has excellent transparency as mentioned above, the thickness of the protective layer can be made relatively large with substantially no influence on the photosensitivity of the photosensitive layer and the mechanical strength thereof is improved. The photosensitive body which is unaffected by temp. and humidity is thus obtd.

Title: Shock wave treatment apparatus
Inventor: KUDO NOBUKI
IPC: A61B17/22
Filed: 1989-04-18
Abstract: PURPOSE:To facilitate work for allowing the focus of a shock wave to coincide with an irradiation target by mounting a distance estimation means estimating the distance from the surface of a living body to the focus of the shock wave when a shock wave applicator is mounted to the surface of the living body and a display means displaying an estimation result. CONSTITUTION:The distance from the surface of a living body to the focus of a shock wave when a shock wave applicator 7 is mounted to the surface of the living body is estimated by a distance estimation means 5 and this estimation result is displayed on a display means 4. Since the depth of an object to be ground from the surface of the body as a shock wave irradiation region is known before treatment, the increase or decrease in the amount of a shock wave transmission medium after the mounting of the applicator 7 can be omitted by preliminarily increasing or decreasing the amount of the shock wave transmission medium in a bag body 8 while the indication result on the display means 4 is looked. Therefore, an operator can easily perform work for allowing the focus of the shock wave to coincide with the object to be ground after the mounting of the applicator 7.
