Title: Type portion material of printing device
Inventor: ASAKURA OSAMU
IPC: B41J1/32
Filed: 1978-11-28
Abstract: PURPOSE: To prevent the ink stains of other parts and the false operation of this printing device resulting from ink stains, by using a type portion material provided with a portion with width wider than the width of types.  
     CONSTITUTION: A type wheel (a type portion material) 2 consists of a type holding ring 2 1  and a type ring 2 2  to which outer circumference a plurality of necessary types 24 are formed. Trapezoid grooves 27 are mounted to the whole circumference of the type holding ring 2 1 , and the type ring 2 2  is fitted and installed onto an outer circumference of the type holding ring 2 1  by fitting a connecting portion 24 1  of an inner circumference of the type ring 2 2  to the grooves 27. The width W 3  of the inner circumference is made smaller than the width W 2  of he outer circumference in connecting portions 27, 24 1  between the type holding ring 2 1  and the type ring 2 2 . Thus, the type ring 2 2  is automatically positioned in the width direction to the type ring 21 only by fitting the inner circumference of the type ring 2 2  to the outer, circumferential grooves 27 of the type holding ring 2 1 . Impregnated ink does not run because the types 24 are positively maintained at fixed locations and force is not applied in the axial directions of the types.

Filed: 1988-06-15
Abstract: PURPOSE:To improve mechanical strength without losing the castability and transferability of the characteristics of a zinc alloy by subjecting steel products for general structural purposes to internal chill with the zinc alloy. CONSTITUTION:Scale, rust, etc., are generally stuck on the surfaces of the steel products for structural purposees and are removed by shot blasting from the surfaces of the steel products; thereafter, the steel products are subjected to a surface treatment for the purpose of surface cleaning by degreasing and pickling. The steel products are subjected to a fluxing treatment in order to improve the joining between the steel products subjected to the surface cleaning treatment and the zinc alloy. The steel products are thereafter heated for a prescribed period of time at a prescribed temp. for the purpose of drying and preheating and are then installed in the prescribed position in a casting mold. The zinc alloy of 420-520 deg.C melt temp. is poured into the casting mold to internally chill the steel products. The preheated steel products are heated by the molten metal and are heated up to the pouring temp. of the zinc alloy but the diffusion at the boundary between the steel products and the zinc alloy is sufficiently accelerated and, therefore, the time to the solidification of the molten metal is maintained and the slow cooling is attained.

Title: Dc-dc converter
Inventor: INABA KATSUHIKO
IPC: H02M3/28
Filed: 1990-06-06
Abstract: PURPOSE:To suppress the flyback voltage generated during off time of a switching transistor so as to prevent this transistor from breakage by supplying the flyback energy of a transformer from the series connection of a switching transistor and a transformer to the DC output part. CONSTITUTION:When a switching transistor 2 is turned on, exciting energy is accumulated in a transistor 1. Next, when the switching transistor 2 is turned off, the exciting energy of the transformer 1 is released from secondary findings N2 and N3 through diodes 3 and 4, respectively. But during the time lag until the exciting energy is released from the secondary windings N2 and N3, primary winding N1 seeks to release flyback energy. The currents at this time, through a capacitor 9 when a transistor 10 is off, and, through a transistor 10 when it is on, are supplied severally to a second Dc output V02. Accordingly, the collector voltage of the switching transistor is suppressed low (above the value of V02).
