Title: Optical element
Inventor: MAEDA YOSHINOBU
IPC: G02F3/00
Filed: 1998-03-09
Abstract: PROBLEM TO BE SOLVED: To obtain an optical element which shows negative optical input-output characteristics for the light of a specified wavelength and which can inverse the light signals at that wavelength by doping a transparent base material with such elements having negative optical input and output for the second excitation light which excites electrons in the first excitation level by the first excitation light to the second excitation level. SOLUTION: A transparent base material is doped with such elements having negative optical input and output for the second excitation light which excites electrons in the first excitation level excited by the first excitation light to the second excitation level. The elements are preferably rare earth elements or transition metal elements, and especially, the element is preferably erbium. The transparent base material is preferably composed of a crystal, glass, semiconductor or ceramic material. For example, the optical element is produced by doping the transparent mother material with erbium which has negative optical input and output characteristics for the second excitation light at 1550 nm wavelength when two kinds of light of the first excitation light at 800 nm wavelength and the second excitation light at 1550 nm wavelength enters as superposed.

Title: Stainless steel having excellent adhesion property of surface film and its production
Inventor: SHIBUYA MASAYUKI
IPC: C23F1/28
Filed: 1997-03-12
Abstract: PROBLEM TO BE SOLVED: To obtain a stainless steel sheet improved in the adhesion property of various kinds of films mainly formed by ceramic thermal spraying by etching the steel sheet with an aq. ferric chloride soln. of a specific concn. and specifying the surface roughness thereof and the relative sectional area in the specific depth position of a relative load curve by its sectional curve. SOLUTION: The surface roughness Ra of this stainless steel is 1.6 to 2.4μ, the Rmax is <=20μ and the relative sectional area (Tp50 ) in the depth 50% position of the relative load curve by its sectional curve is <=70%. This surface condition is obtd. by subjecting the steel sheet to spray etching by using the aq. ferric chloride soln. kept at 33 to 37 deg.Be' (Baume degree). As the surface roughness Ra is generally higher, the adhesion property of the films improves but >=1.6μ is necessary in order for obtaining the effect of improving the adhesion property by the shape of the relative load curve. If, on the other hand, the aq. ferric chloride soln. is excessively higher, the film thickness partially exceedingly decreases and, therefore, the surface roughness is confined to <=2.4μ and the Rmax to <=20μ.  If Tp50 exceeds 70%, the sufficient adhesion property is not obtainable.

Abstract: PURPOSE:To control a reverse bias current constantly irrespective of the variation in a power source by connecting a circuit which includes a constant-voltage element in parallel with an electric circuit which supplies a reverse bias current and clamping the voltage in the circuit. CONSTITUTION:A series circuit of a diodes D11 and a Zener diode ZD10 is connected between a point (A) and a point (O) in a circuit, and a resistor R9 is inserted to the emitter side of a reverse bias transistor T4.

IPC: H01L29/73
Filed: 1978-05-15
Abstract: PURPOSE: To increase the adhesive force when the back surface of the semiconductor substrate  containing each element region formed is adhered to a container or the lead frame by removing  the layer containing the P- and N-type impurities occurring on the back surface and then providing newly the high-density layer of thd same conducting type as the substrate.   
     CONSTITUTION: N-type buried region 2 is formed by diffusion on P-type semiconductor substrate  1, and then N-type layer 3 is epitaxial-grown on the entire surface including region 2. Then P- type region 4 reaching up to substrate 1 is formed by diffusion at layer 3 to isolate layer 3 into an  island form. After this, P-type base region 5 is formed by diffusion within isolated layer 3, N-type  emitter region 6 is provided within region 5, N-type collector contact region 7 is formed by diffusion at the place distant away from region 5, and the entire surface is covered with SiO 2  film 8.  Then the aperture is drilled to film 8 with attachment of electrode 9 at each region. At the same  time, layer 10 is polished away from the back surface of substrate 1, and layer 10 contains both  N- and P-type impurities which are caused during the above processes. As layer 10 which has the  inferior adhesion to the container is removed away and P-type layer 11 of a high impurity density  is added, the adhesive performance can be enhanced extremely.

IPC: F16K11/06
Filed: 1985-03-22
Abstract: PURPOSE:To provide practicability of using any type of hydraulic pump by installing a high pressure restricting valve in the hydraulic circuit in the direction of press machining and a low-pressure restricting valve in the circuit in the return direction. CONSTITUTION:As processing by a tool head proceeds, the oil pressure rises and when the mechanical limit for machining is reached, the oil pressure rises up to the relief pressure set value on a high-pressure restricting valve 27. As a result, relief is made by this high-pressure restricting valve 27 to cause the oil pressure to sink to zero, and on the way thereof a handle 1 returns to the neutral position automatically. When the handle 1 is turned to allow a moving piece of the tool head to operate for the return action, the oil line 15 leads to the one 19. If at this time a low-pressure restricting valve 24 makes relief action, the oil pressure sinks to zero.
