Title: Semiconductor basic material and production thereof
Inventor: SATO NOBUHIKO
IPC: H01L21/322
Filed: 1996-10-04
Abstract: PROBLEM TO BE SOLVED: To provide a method for producing a flat SOT basic material having sufficient quality with high reproducibility while saving the resource and realizing cost reduction by reusing the material. SOLUTION: The method for producing a semiconductor basic material comprises a step for making porous an Si basic material and to form a porous Si layer 42 at least on the surface thereof, and a step for forming a porous Si layer 44 having high porosity in the porous Si layer 42. The step for forming a high porosity layer can be carried out by injecting ions into a porous Si layer at a specified projection range, or varying the current density at the time of anodic formation during the step for forming a high porosity layer. In this regard, a nonporous single crystal Si layer 43 is grown epitaxially on the porous Si layer 42. Subsequently, the surface of porous Si layer 42 is pasted to a supporting basic body 45 and separated through a porous Si layer 44 having high porosity. Finally, the porous Si layer 42 is removed by selective etching.

Filed: 1999-09-17
Abstract: PROBLEM TO BE SOLVED: To prevent the useless image forming operation in superposition on an already recorded surface when recording paper already formed with an image on one surface is going to be reused. SOLUTION: Whether there is the already recorded image on a first surface to be recorded of the fed recording paper or not is detected by a line sensor 20.

IPC: H02K5/173
Filed: 1990-10-01
Abstract: PURPOSE:To prevent comparatively great thermal stress from being applied to a bearing means and the means from deforming by making a thermal deformation absorption annular recession in a specified part of a hub means. CONSTITUTION:A bearing 6 has an inner ring 38 fastened to a shaft 16, an outer ring 40 arranged outside the inner ring 38, and a plurality of balls 42 between the inner and outer rings 38 and 40.

Filed: 1989-10-13
Abstract: PURPOSE:To accurately shift slide cores and consequently perform injection molding without impairing the external appearance of a molded item by a structure wherein a mold, which has sliding holes near an injection hole, has a projection train, which forms the openings of the sliding holes at the shifting ends o the slide cores in the space in the mold. CONSTITUTION:Primary resin, which is injected in the space 32 in a mold, is formed in a shape, which is partitioned by a fixed mold 20, a movable mold 22 and slide cores 26 and 30, so as to be turned into a cassette half main body. After the primary resin injected almost solidified, the slide cores 26 and 30 are retreated in sliding holes 24 and 28 in order to form window part space 36. The slide core 26 is retreated to the position, which coincides with the inner mold surface of a fixed block 25 provided in advance at the position equal to the thickness of a window part. Since the slide core 26 on the fixed mold side at the position abutting against the slide core 30 on the movable mold side is surrounded by a projection train 38, the stable sliding of the slide core 26 is ensured, even when the slide core 26 expands due to the heating of a direct gate 34 or to the heat of molten resin injected secondarily.

Abstract: PURPOSE:To prepare a nut-containing rice cracker giving soft feeling to the palate, by using nuts, processed nuts, etc., as a core material, applying molasses and starch to the core in multiple layers, attaching gelatinized rice to the obtained granule and frying the product in an oil. CONSTITUTION:For example, the outer surface of almond 1 is alternately coated with molasses and starch to form intermediate multiple layers 2 satisfying the formula 0.3<=A<=a<=0.9 (A is total amount of molasses and starch; a is deposited amount before intermediate drying process). The obtained granule is dried at 100-120 deg.C for <=30min to attain a water-content of <=0.4, coated with dried glutinous rice grains 3 and fried in an oil to obtain the objective nut-containing rice cracker. Since the intermediate granulation layer is quickly dried, the migration of water to the nut is suppressed, the adhesion of the gelatinized rice is smoothly performed and the taste and flavor of nut can be retained.

Filed: 1987-10-20
Abstract: PURPOSE:To prevent possible bend of a cutting face at the time of cutting to maintain verticality of a segment by tilting steps provided on both sides of the segment containing diamond grits from a tangential direction. CONSTITUTION:A bias-step-segment type diamond blade is formed by attaching plural segments 7 containing diamond grits to the outer peripheral side of supporters 6.

As a result, when the segment 7 was subject to wear unequally developed in the radial direction, the distance from a center line in the cross direction of the segment 7 to both right and left sides are maintained to be equal. Bend of a cutting face from vertical can therefore be prevented as much as possible, and verticality of the segment can be maintained.

Filed: 1989-10-12
Abstract: PURPOSE: To eliminate the need to execute an initialization sequence each time user's environment changes by providing an additional peripheral device state or constitution storage register and a new software driving means which dynamically reconstitutes a system without interacting with a user. CONSTITUTION: When the system is started, system software makes a polling for the current state and data regarding the state are stored in proper data registers in a CMOS circuit 24. The current data in those constitution registers are compared with data in a system memory table relating the last constitution of the system to judge whether or not the constitution state needs to be changed. With many instruction sequences stored together with the start-time initialization command of the system, a processor 10 reads the states of peripheral devices and system variables out and stores constitution data relating to detected changes to update the system constitution without interacting with the user. Consequently, the computer can easily be used.
