Filed: 1999-07-29
Abstract: PROBLEM TO BE SOLVED: To improve saturation magnetic flux density (BS) of a ferrite material, while keeping its superior sintered quality, permeability, and resistance as they are, by imparting it with respectively with Fe2O3 and CuO of a specific mol% and ZnO/NiO of a specific mol ratio, as its main components of the oxides of Fe, Zn, Ni, and Cu, and by making it include respectively Bi2O3 and V2O5 of specific pts.wt., as its auxiliary components. SOLUTION: A ferrite material of a high saturation-magnetic-flux density has oxides of Fe, Z, Ni, and Cu as its main components, i.e., has respectively Fe2O3 of 48-50 mol%, CuO not higher than 3 mol%, and ZnO/NiO of 0.6-0.8 mol ratio.

Title: Semiconductor device
Inventor: NAKAMURA MINORU
IPC: H01L31/10
Filed: 1990-08-14
Abstract: PURPOSE:To increase the heat generation of electron-hole pairs at the lower end section of a depletion layer extending from a P-N joint surface, and to improve sensibility by forming an insulating layer having specific thickness under an element forming region. CONSTITUTION:Light projected to a photodiode PD is reflected by each interface, the interface (a) of an insulating layer 15 and an element forming region 5n and the interface (b) of the insulating layer 15 and a silicon substrate 1p, of the insulating layer 15 by forming the insulating layer 15, and the attenuation of the quantity of light absorption in the depth direction of a depletion layer extending from a P-N joint surface (j) can be inhibited. The quantity of light absorption is increased more remarkably especially when the film thickness (t) of the insulating layer 15 is set so that light reflected by each interface (a) and (b) is maximized by mutual interference action-that is, reflected light is brought to phase-shifting relationship, in which reflected light is intensified mutually, thus augmenting the generation of electron-hole pairs at the lower end section of the depletion layer, then improving the sensibility of the photodiode PD.

IPC: B60S1/34
Filed: 1993-08-06
Abstract: PURPOSE:To offer a vehicle windshield wiper not having its slide drive mechanism made in a large size but easy to be assembled. CONSTITUTION:The side surface of the interior of a No.1 arm 11 has a fixed rack 13 integrated thereto and the rear end side of the wiper of a No.2 arm 12 has a movable rack 14 fitted thereon in such a manner as opposing to the fixed rack 13. Further, a gear 36 is engaged with the fixed rack 13 and the movable rack 14 from both sides and because a link mechanism 30 causes the gear 36 to make its reciprocating movement along the fixed rack 13 in accordance with the turn of a No.2 lever, the movable rack 14 makes its reciprocating movement accompanying the movement of the gear 36. Thus the No.2 arm 12 is forcibly expanded and contracted against the No.1 arm 11.

IPC: C23F1/00
Filed: 1993-08-31
Abstract: PURPOSE:To retard formation of a nonreaction polymer layer through exposure at the lower part of resist by employing a chemical amplifying resist having double structure wherein the resist for lower layer has higher concentration of acid generating agent than the resist for upper layer. CONSTITUTION:A thin first resist layer 2 having high concentration of acid generating agent for making up the deficiency of acid is formed on a semiconductor substrate 1 and a second resist layer 3 having lower concentration of the acid generating agent than the first resist layer 2 is formed thereon. The resist employs polyvinylphenol as the base resin and an onium salt as the acid generating agent. The substrate 1 is then exposed by an irradiating light 4 from an excimer laser stepper through a line and space pattern mask followed by heating in a clean oven. This method retards formation of unreaction polymer layer due to missing of acid generating agent.
