Title: Surface inspector
Inventor: HOURAI MOTOO
IPC: G01B11/30
Filed: 1984-12-05
Abstract: PURPOSE:To eliminate variations in the judging of defects, by making the beam spot oval while the scanning speed is kept constant throughout the inspection processes to ensure a large feeding pitch in the spiral scanning. CONSTITUTION:Light beam from a laser 1 is expanded in the beam spot diameter radially with respect to a sample 6 (semiconductor wafer) to be inspected with an oval beam expander 3 and focused with a condenser 4 on the surface of the sample in a small oval shape. Scattered light from a defect on the sample 6 is made incident into a detector through an optical fiber 14. A spindle 7 having the sample 6 sucked securely thereon is turned with a DC motor 9 and a timing belt at the speed corresponding to the radial position of scanning. A moving table 11 for radial scanning is moved with the DC motor 9 at a variable speed corresponding to the radial position.

Title: Hot rolling method for high si content grain oriented electrical steel
Inventor: MOCHINAGA KISHIO
IPC: C21D8/12
Filed: 1985-11-16
Abstract: PURPOSE:To decrease the edge cracks of a hot rolled sheet in the stage of subjecting a high Si content grain oriented electrical steel slab to hot rolling by specifying the coolest point temp. of the slab in the heating zone of a continuous heating furnace and the surface temp. of the slab in the soaking zone. CONSTITUTION:The grain oriented electrical steel slab contg. >=3.0% Si is heated in the continuous heating furnace and is then cross-rolled by edger rolls in a hot rolling stage to prevent the generation of the edge cracks of the hot rolled sheet. The slab in the heating zone of the continuous heating furnace is heated to the temp. range of 1,280-1,380 deg.C with the coolest point (central part in the thickness direction) of the slab. The surface temp. of the slab is 1,330-1,410 deg.C. The slab surface temp. in the subsequent soaking zone is so maintained as to attain the temp. range between the temp. lower by 10 deg.C than the surface temp. of the slab in the heating zone and 1,420 deg.C. The edge cracks to be generated in the stage of cross-rolling the high Si content grain oriented electrical steel slab with the edger rolls are considerably decreased and the yield is improved.

Title: Curing agent for epoxy resin
Inventor: INAGAKI HIROYUKI
IPC: C08G59/42
Filed: 1991-09-09
Abstract: PURPOSE:To obtain the subject agent which can give a cured epoxy resin excellent in heat resistance and mechanical strengths by mixing a specified dicarboxylic anhydride with tetrahydrophthalic anhydride. CONSTITUTION:The objective epoxy resin curing agent is obtained by mixing 5-(2,4-dioxotetrahydro-3-furanylmethyl)norbornane-2,3-dicarboxylic anhydride (A) with tetrahydrophthalic anhydride (B). When a conventional dibasic acid anhydride such as hexahydrophthalic anhydride is used, the heat resistance of a cured product is insufficient, and when an acid anhydride curing agent such as pyromellitic anhydride is used, the heat resistance of a cured product is excellent, but it is difficultly mixable with an epoxy resin because of its high melting point. When the component A is used alone, it is easily handled and can give a cured product of excellent heat resistance, but the cured product is defective in hardness and brittleness. By mixing the component A with the component B, the resulting mixture can give a cured product excellent in heat resistance and mechanical strengths.

Title: Air-fuel ratio control method for internal combustion engine
Inventor: MIYASHITA YUKIO
IPC: F02D45/00
Filed: 1990-09-26
Abstract: PURPOSE:To secure stable engine speed as checking any increase of a torque shock by setting a change speed of desired air-fuel ratio in a rich direction to be the larger, the smaller in engine speed, when the desired air-fuel ratio is changed to the rich direction from the value at the lean side from a theoretical air-fuel ratio. CONSTITUTION:During engine driving, various engine driving states are discriminated on the basis of a variety of engine parameter signals, while a fuel injection time for a fuel injection valve 6 is operated according to the engine driving state at an electronic control 5. Then, an air-fuel mixture is feedback-controlled to a desired air-fuel ratio conformed to the engine driving state. In this case, when the desired air-fuel ratio is changed in a rich direction from the value at the lean side from a theoretical air-fuel ratio, a change speed of the desired air-fuel ratio is set to the larger, the smaller in engine speed. In addition, when an engine is in an idling state, the change speed of the desired air-fuel ratio should be set to be larger than at time of a driving state other than the idling state. With this constitution, any possible worsening of drivability is prevented and thereby the stabilization of engine speed is well promoted.
