Title: Reflection type display device
Inventor: IGARASHI TAKAHARU
IPC: G02F1/1335
Filed: 1990-01-31
Abstract: PURPOSE:To reduce projection light and make a driving voltage low by providing a scattered light absorbing film part between a liquid crystal film and a reflecting plate. CONSTITUTION:The scattered film absorbing film part B which has a light absorptive wall surface perpendicularly to the film surface of the liquid crystal film A is provided between the film A and reflecting plate 15. When a transparent counter electrode 13 is applied with a voltage, the liquid crystal in a capsule 12 is rearranged in an electric field direction and light travels to pass through the scattered light absorbing film part B without striking on the light absorbing wall surface 17 and is reflected by the reflecting plate 15 and projected to the top surface side. When the voltage applied to the counter electrode 13 is ceased, the liquid crystal in the capsule 12 is arrayed along the internal surface of the capsule 12, so the light incident on the liquid crystal film A is scattered at a liquid crystal capsule part and absorbed by the light absorbing wall surface 17 by striking on the wall surface and the reflected light from the reflecting plate is absorbed similarly. Consequently, the projection light is reduced and the driving voltage is made low.

Title: Sheet folding device
Inventor: SAITOU AKIO
IPC: B65H45/101
Filed: 1983-02-10
Abstract: PURPOSE:To fold the trailing edge of a sheet by allowing a swing fin to swing much at the time of terminating treatment of the sheet. CONSTITUTION:A sheet cutting means (blade) 7 is installed ahead a swing fin 8 to fold a sheet 1 turned over and back alternately by swinging in one reversal every time two pages of sheets 1 are fed. Sheet feed signals similar to the cut sheet feed signal are generated by this blade 7 more in amount than corresponding to the distance from the sheet cutting position to swing fin 8, and these sheet feed false signals are used to allow said swing fin 8 holding the trailing edge of the sheet 1 cut by the blade 7 to swing more frequently than in normal folding operation. Thus the sheet 1 is pushed out toward a table 9, and the trailing edge can be folded in surely.

Title: Manufacture of spheroidal graphite niresist cast iron
Inventor: SETO MASAHIRO
IPC: C21C1/10
Filed: 1989-01-31
Abstract: PURPOSE:To improve flowability without deteriorating strength, heat resistance, and corrosion resistance by using, as an inoculant, a mixture of Fe-Si, Sb, Ca-Si, and rare earth metals at the time of spheroidizing graphite in Niresist cast iron of high Ni content and manufacturing ductile Niresist cast iron. CONSTITUTION:Niresist cast iron containing >=30% Ni has extremely superior corrosion resistance. This Niresist cast iron, however, is formed into ductile Niresist cast iron by means of graphite spheroidizing because the graphite in the structure is flake graphite, but this ductile Niresist cast iron is poor in casting characteristics as well as in flowability. In order to improve the above characteristics, a mixture which consists of 0.1-0.3% Fe-Si, 0.01-0.05% Sb, 0.01-0.03% Ca-Si, and 0.005-0.03% rare earth metals having a composition in which the ratio of Ce to La is 2 to 1 is added as an inoculant to the molten Niresist cast iron. By this method, castability as well as flowability can be improved without deteriorating the high strength, heat resistance, and corrosion resistance of the Niresist cast iron.
