Abstract: PURPOSE:To obtain a laser whose active layer is narrow, whose oscillation mode is stable and whose threshold electric current is low by a method wherein an inverted-mesa-shaped part is formed by using a first etching solution and, in succession, a vertical-shaped part and a forward-mesa-shaped part are formed by using a second etching solution. CONSTITUTION:A p-type InP clad layer 12, an InGaAsP active layer 13 and an n-type InP clad layer 14 are formed on a p-type InP substrate 11. A stripe-shaped SiO2 film 23 to be used for a mask is formed on the layer 14; an etching process is executed up to the clad layer 12 over the active layer 13 by using a solution of Br2-CH3OH as a first etching solution so as to form an inverted-mesa-shaped part 20; then, another etching process is executed up to an intermediary part of the substrate 11 by using another solution of hydrochloric acid as a second etching solution so as to form a vertical-shaped part 21 and a forward-mesa- shaped part 22. Then, a p-type buried layer 15, an n-type buried layer 16 and a p-type buried layer 17 are formed in succession at the circumference of these mesa stripes. If the etching process is executed in such a way that the active layer 13 is situated near the part connecting the inverted-mesa-shaped part 20 to the vertical-shaped part 12 the width W of the active layer can be narrowed. By this setup, it is possible to stabilize an oscillation mode of a laser beam and to lower a threshold electric current while a high output is maintained.

IPC: H01L31/042
Filed: 1980-03-25
Abstract: PURPOSE:To utilize the incident light effectively by forming a diffused reflection part of the bottom surface opposite to the light incident surface window in a case surface. CONSTITUTION:Circular solar cell elements 1a contribute the light electromotive current caused by the incident light even from the bottom surface. The diffused reflection surface is formed on the inner surface of a bottom plate 31 of a case body 3. The diffused reflection plate 31 is formed by evaporating a thin metal film on the convex and concave surface of a resin plate. The thickness L of the solar cell  element is so selected that reflected light 8 from the bottom surface contributes effectively to the light electromotive current and the length is smaller than the diffusing  length of a minority carrier of the constituting material of the bottom surface of the  element. A part which is not covered by electrode metal is provided on the bottom  surface of the elements. In this constitution, a part of a light 7 which might be  useless can be utilized as a light 10 which is reflected by a window plate 2, thus both parts contribute to the light electromotive current. Therefore the area of the  ineffective light receiving surface is decreased, and the photoelectric conversion  efficiency can be increased.

Filed: 1997-02-08
Abstract: PROBLEM TO BE SOLVED: To prevent a packing from locally rising due to reaction at the time of bridge breakage by presetting strength of a bridge positioned at a predetermined angle in a circumferential direction from an upper end of a female screw of a cap to be weak. SOLUTION: Cross sectional areas of bridges 42, 41, 42 provided in an opposite region in an approximately diameter direction of an upper end 311 of a male screw 31 in contact with a flange of a packing are set to be smaller than that of another bridge 4, and their tensile strength is set to be weak. The tensile strength of the center bridge 41 is set to be the smallest, that is weaker than that of the bridges 42 at both sides. At the time of unplugging, the bridges are broken sequentially from the weaker bridge 41, wherein reaction at the time of breakage is locked by engagement of both screws and may not arrive on the packing. Therefore, such a situation that the packing is locally pushed up by reaction due to the breakage of the bridge 41 and it may be forced to open slantly can be prevented, thereby preventing leakage in airtightness.

Abstract: PURPOSE: To change the moving speed of scanning system or photoreceptor easily and correctly according to the modification of magnification of the original, by providing a means to change the speed of driving means by controlling the signal generating means depending on the set magnification.  
     CONSTITUTION: A film transfer motor M 1  and a photosensitive drum rotation motor M 2  are synchronous motors capable of obtaining rotating speed synchronized with independent frequencies. The synchronization control circuit for both motors generates a reference signal frequency f 1  in a reference signal generator circuit 50, and delivers output frequency f 2 =f 1 /n through frequency dividing circuits 51, 52. The output frequency from the circuits 51, 52 drives the motors M 1 , M 2  so that film M and drum 20 may move at the speed corresponding to the projection magnification, through sine wave generator circuits 53, 54 and amplifier circuits 55, 56. Since the rotation speed of the drum 20 is at the reference speed, the frequency of the circuit 52 is kept constant, and the frequency of the circuit 51 is varied depending on the projection magnification, optical path length, focal length, and other factors. Due to the frequency signal corresponding to the copying magnification from the dividing circuits, the moving speed of the film may be changed easily and promptly.

Abstract: PROBLEM TO BE SOLVED: To obtain an antibacterial structural material comprising a safe inorganic substance by a method wherein a photoelectric conversion layer is so arranged to perform a photoelectric conversion of visible light and positive holes in the photoelectric conversion layer generated by irradiated light are supplied onto the topmost surface of the structural material. SOLUTION: An n-type amorphous silicon layer 2, an i type amorphous silicon layer 3 and a p-type amorphous silicon layer 4 are laminated on a substrate 1 comprising a stainless sheet to form a photoelectric conversion layer. A diamond-like carbon layer 5 is formed on the p-type amorphous silicon layer 4 to make a protective layer. When the work thus obtained is irradiated with light, the i-type amorphous silicon layer 3 absorbs the light to generate positive holes and electrons. The positive holes are supplied to the diamond-like carbon layer 5 from the p-type amorphous silicon layer 4 by an internal electric field. The generated electrons are supplied to a substrate 1 from the n-type amorphous silicon layer 2.  Moisture adsorbed on the surface of the diamond like carbon layer 5 is oxidized by the positive holes to be turned to a hydroxyl radial with higher oxidizing capability thereby developing an antibacterial property.

Abstract: PURPOSE:To obtain a semiconductor device in which NMOS and PMOS transistors are electrically isolated from each other by epitaxially growing a monocrystal semiconductor on a porous base and forming a dielectric layer by ion implantation. CONSTITUTION:In an active layer 2 of a PMOS transistor, an n-type channel section 24, a p-type drain region 25 and a source region 26 are formed. In an active layer 12 of an NMOS transistor, a p-type channel region 27, an n<+>-type drain region 28 and a source region 29 are formed. Second gates of the PMOS and NMOS transistors are doped to form an n-type semiconductor and a p-type semiconductor, respectively. The second gates 1 and 11 and the active layers 2 and 12 are made of a monocrystal Si thin-film. A monocrystal Si thin-film between the transistors is oxidized to SiO2 which acts as a dielectric layer by the LOCOS oxidation method. Other areas are simultaneously subjected to the doping of Si when ions are implanted into the second gates. Accordingly, first and second gate connecting sections 6 and 16 are located near to the transistors, whereby excessive interconnections are hardly produced. Hence, the first and second gates can be controlled simultaneously.
