Filed: 1990-04-25
Abstract: PURPOSE:To always and effectively prevent the adverse effect of stray light even if the relative positions of a light source body and a follow-up reflecting mirror are changed continuously by providing a light shielding means always moving a light shielding body to the most effective position and controlling it. CONSTITUTION:An exposing/scanning means 21 has the light shielding body freely movably provided between an original platen 12 and the follow-up reflecting mirrors 24a and 24b, and the light shielding means 28 moving the light shielding body to a set position according to an interval between the light source body 22 and the follow-up reflecting mirrors 24a and 24b, and shielding the light of the light source body 22 reflected on the back surface of the original platen 12 and made incident on the follow-up reflecting mirrors 24a and 24b. Thus, since the light shielding body is moved to the set position according to the interval between the light source body and the follow-up reflecting mirrors, the stray light is effectively shielded by properly providing the set position.

Title: Semiconductor storage device
Inventor: OKAJIMA YOSHINORI
IPC: G11C11/34
Filed: 1984-05-29
Abstract: PURPOSE:To reduce a holding current for a large volume of stored information by supplying the holding current periodically to saturation type memory cells. CONSTITUTION:Saturation type memory cells MC0n-MCmn are connected to word line couples WL0 and WL'0-WLm and WL'm. When an oscillation circuit OSC1 generates a control signal of ''H'' with specific pulse width at a constant period, an NPN transistor Tr2m+1 turns on and a PNPTr2m+1 turns on, and then an NPNTr2m+1 turns on. Thus, the Trs turn on one after another and the holding current flows through respective word lines with a slight time lag. Then, information holding Trs are saturated and it takes a time to couple base and collectors, so that the response of an internal potential to current variation is slow and stable.

Abstract: PROBLEM TO BE SOLVED: To improve the surface hardness of a shaft member without impairing corrosion resistance and to satisfactorily prevent the generation of dent scars by cold-machining an austenitic stainless steel raw material at a specific machining ratio to specific surface hardness to form the shaft member. SOLUTION: A rotary shaft 21 is formed from an austenitic stainless steel (SUS 301, 303, or 304) through normal hot machining and cold machining. The cold machining ratio, i.e., area reducing ratio of cross sectional area, is set to 20% or above, and the surface hardness of 300 Hv or above is achieved. In cold machining, the outer diameter size is gradually squeezed by cold rolling cold drawing, and the squeezing degree, i.e., cold machining ratio (area reducing ratio), is increased to increase the hardness of a surface layer portion. The corrosion resistance by the passive state film of the stainless steel can be maintained as it is, and dent scars by impacts can be satisfactorily prevented.

IPC: B32B27/00
Filed: 1996-04-26
Abstract: PROBLEM TO BE SOLVED: To visualize a design with transparency, feeling of depth and high grade touch by stacking a transparent thermosetting molding material and a transparent or a colorable thermosetting molding material in such a manner that a thermoset product of the thermosetting molding material is interposed between both materials, and molding all of these materials under thermal pressure. SOLUTION: This molding is of the laminated state and obtained by thermally pressing, for example, a colorable thermosetting molding material layer 7, a thermoset product 3 of a colorable thermosetting molding material and a transparent thermosetting material layer 5 stacked in that order. In addition, a pattern material can be mixed into the thermosetting material for the thermoset product 3. The transparent thermosetting material and the colorable thermosetting material are not mixed in the part where the thermoset product 3 is present. Therefore, no pattern is visible in the shallow layer, for example if viewed from the surface, but the pattern is visible in the deep layer. Also the pattern in the shallow layer and that in the deep layer are visible three-dimensionally. Thus it is possible to obtain a molding with transparency, feeling of depth and also high grade touch design.
