Title: Fabricating method of semiconductor device
Inventor: TAKAGI MIKIO
IPC: H01L21/768
Filed: 1979-03-30
Abstract: PURPOSE:To fabricate a semiconductor device in high reliability and yield by irradiating a laser light of long wavelength to the vicinity of an impurity containing glass film including contact hole to melt and soften the film and forming round edge of the contact hole. CONSTITUTION:A second PSG insulating film 4 is grown, then patterned, and formed with a through hole 4A thereat. A laser light of long wavelength such as CO2 laser is suitably focused and irradiated only to the vicinity of the through hole 4A. The light by the CO2 laser is absorbed by approx. 70% to a PSG, but almost reflected by 100% by aluminum. Therefore, the film 4 is molten and softened only at the periphery of the through hole 4A, and roundness is formed at the edge.

Title: Humidifier
Inventor: NAKAKOSHI MICHIO
IPC: A61M16/16
Filed: 1999-02-17
Abstract: PROBLEM TO BE SOLVED: To obviate the occurrence of humidifying gas leakage even with weak force by forming a sealing means for sealing a cap means and a receiving means to each other to structure having a shape continuous over the entire circumference of the sealing surfaces of the cap means and the receiving means and having a lip portion thinly rising with respect to a mother sealing material. SOLUTION: The gas to be humidified flows in from an inflow port 1. When the gas passes the front surface of the humidifying water 9 packed in the receiving means 3 by the mixing port of the humidifying device, the gas is humidified by evaporating moisture and is then made to flow out of an outflow port 2. The receiving means 3 and cap means 4 of such humidifying device is hermetically closed by the sealing means 5 disposed therebetween. The sealing means 5 is formed of silicone rubber, etc., to the shape projectingly provided with the thin lip portion 5b diagonally from the terminal of the sealing portion 5a in a direction of 45 deg. toward the inner side. As a result, the expansion of the margin for compress of the seal is made possible and reduction of the operating force for effectively maintaining the seal between the receiving means 3 and the cap means 4 is made possible.

Abstract: PROBLEM TO BE SOLVED: To measure the temperature at a local high temperature part of an object by winding an optical fiber sensor, obtained by bonding a single optical fiber onto a supporting member in ring shape, around an object and measuring the backscattering light of the optical fiber. SOLUTION: An optical fiber 1 is coiled by several turns with diameter D of about 60 mm and bonded onto a thin plate 7 of copper, nickel, or the like, having width W of about 70 mm at an interval L of about 600 mm in the longitudinal direction to form an optical fiber sensor 8. The sensor 8 is then wound round a high temperature piping (object) A at a specified interval and backscattering light is measured thus measuring temperature distribution at each position of the piping A by means of a temperature distribution meter 2. When a sensor 8 comprising an optical fiber 1 turned twice with diameter D of about 60 mm is used, for example, total length of the fiber 1 exceeds 3 m at a local high temperature part (hot spot) 6 of 100 deg.C and a highest temperature part of about 100 deg.C can be detected. Temperature can be measured even when the area of high temperature part of object A is small and the temperature increases locally.

Title: Wire cut electric discharge machine
Inventor: MAGARA TAKUJI
IPC: B23H7/02
Filed: 1987-02-23
Abstract: PURPOSE:To improve accuracy of machining in a corner part, by providing the first control unit controlling a machining speed to be locked to a predetermined value by signals of the first and second discriminators and the second control unit switching a servo gain in an out-corner part from the signal of the second discriminator. CONSTITUTION:During finish machining, a control unit 16, by a signal of the second discriminator 14, switches a servo gain so as to be high increased in an out-corner part. In this way, a machine, rapidly increasing a machining speed in a linear part immediately before change of direction, reduces an overhung amount. After a wire electrode 1 passes through the linear part immediately before the change of direction, the machining speed further rises, but here a control unit 13, by signals of the first and second discriminators 12, 14, controls the machining speed to be locked so that it is prevented from increasing to a predetermined value or more when the machining speed reaches the predetermined value. Consequently, the machine, which decreases the machining speed promptly in the linear part immediately after the change of direction in an edged part, generates no overshoot and no overhung and undercut as in the past.

Abstract: PROBLEM TO BE SOLVED: To prevent the quality of dynamic picture from being deteriorated by constituting the arrangement of subfields being in one field so that subfields of other display periods are arranged in between the subfield of the shortest display period and the subfield of the second shortest display period. SOLUTION: Subfields being in one field are arranged in the order of b1, b3, b5, b7, b6, b4, b2 and b0.

In this subfield arrangement, in the case of change between b0 and b1 or the like at the changeover of field. Namely changes between subfield low in gray level, since it is the change in dark display level area, the remarkable degradation of picture quality is hardly caused even when a non-luminescent time is prolonged.
