Title: Manufacture of semiconductor device
Inventor: OHARA KATSUMI
IPC: H01L21/316
Filed: 1986-08-22
Abstract: PURPOSE:To determine correctly a crosswise region length of a semiconductor region by forming the first-third oxide films having different film-thicknesses at and around the center on the semiconductor region and introducing impurities through an opening formed in these oxide films. CONSTITUTION:The first SiO2 film 18 having a width of L, the second and third SiO2 films 19a and 19b having less than a half film thickness of the film 18 are formed on a semiconductor region 3. And after the third SiO2 film 19b and a part of the first SiO2 film 18 have been coated with resist film 20, an opening 21 is formed through etching treatment. And then, impurity ions are implanted through the opening 21 to form a p-type region 4. In like manner, the opening 24 is formed at left side of the substrate and an ion implantation is carried out to form an n<+>type region 7a. This approach helps determine a crosswise region lengthl of the semiconductor region 3 located between the n<+>type region 7a and the p-type region 4 with high accuracy without performing an expensive photo mask alignment.

IPC: B29C70/06
Filed: 1996-07-26
Abstract: PROBLEM TO BE SOLVED: To provide a laminate easy-to-handle in case of cutting or packaging, and easy-to-use at the time of using by a user. SOLUTION: Glass woven fabric is impregnated with epoxy resin varnish, and dried to prepare a prepreg for molding the laminate. Prepreg layers made of four prepregs and release films (polypropylene films) are alternately repeatedly laminated for 300 laminates, and the release films are disposed on the uppermost and lowermost surfaces. It is thermally press molded between press heating platens via a cushioning material without sandwiching it between mirror surface plates. The laminate manufactured in this manner becomes the state that 300 laminates are integrated via the release films. The laminate is cut at its circumference by a predetermined size as remained in the state that the 300 laminates are integrated via the release films, and the laminate which is still retained as integrated via the films is packaged.

Filed: 1996-07-26
Abstract: PROBLEM TO BE SOLVED: To precisely detect the residual quantity of a toner and to prevent the toner from leaking by providing a developing machine with a self-weight detecting part and a toner surface detecting member, which is connected to the self-weight detecting part via a suspending member. SOLUTION: A toner surface detecting member 3 is suspended from a self- weight detecting part 2 by means of a suspending member 2a, and it sits on the surface of a toner 7 without being buried in the toner, when the surface of the toner 7 within a developing machine 1 is above a prescribed level. However, if the surface of the toner 7 goes down below the prescribed level, the toner surface detecting member 3 is parted from the surface of the toner 7 to be suspended within the developing machine 1. In this state, the self-weight detecting part 2 consisting of a small sensor detects the self-weight of the toner surface detecting member 3 being suspended.  By detecting the variation in the pressure, which is caused by the fact that the toner surface detecting member 3 became being suspended, it is known that the surface of the toner within the developing machine 1 went down below the prescribed level.

CONSTITUTION:By the rotation of a motor 1, a presser rotor 16 is also rotated with the magnetic disk 7, and the air flow is generated by a fan 19, and it is propagated through an ventilator,then it blows out from an air blowout exit 20, and strikes the plane of the magnetic disk 7 coming in contact with the magnetic head, and the plane on the opposite side. Since the air blowout exit 20 is provided at a position separated a little from a part confronting with the magnetic head 10, the blown out air evades the center point of the part of the magnetic disk 7 coming in contact with the magnetic head 10, and strikes the side part in a concentrated way, and the magnetic disk 7 is brought into contact by pressing with the magnetic head 10, by the pressure of spraying air. In this way, it is possible to prevent the recording plane of the magnetic disk 7 from wearing beyond the minimum level, and to rotate the disk at high speed.
