Title: Picture recorder
Inventor: SETO KAORU
IPC: G02B26/12
Filed: 1986-10-07
Abstract: PURPOSE:To simplify a scanning optical system by reflecting laser beams radiated from one light source by plural reflecting faces of a rotary polygonal mirror which have different inclination angles respectively and exposing plural images on the different positions of an image carrier. CONSTITUTION:Laser beams 3, 6 modulated by 1st and 2nd image signals VD01, VD02 are radiated from a semiconductor laser 12 and reflected by the polygonal mirror 14 to execute raster scanning. At that time, the laser beam 3 modulated by the 1st image signal VD01 is reflected by the odd number-th reflecting faces of the rotary polygonal mirror 14 to execute raster scanning L1 and the laser beam 6 modulated by the 2nd image signal VD02 is reflected by the even number-th reflecting faces to execute raster scanning L2. Since only one semiconductor laser 12, one driver for driving the laser 12 and one rotary polygonal mirror 14 are required, the cost and size of the device can be sharply reduced.

Title: Gas burner for cooling unit
Inventor: MURAMOTO AKIRA
IPC: F23D14/06
Filed: 1984-11-09
Abstract: PURPOSE:To enable the prevention of back-fire or explosion sound by a method wherein a gas chamber is constituted by an upper part of a main body of burner having gas injection holes formed therein, an upper part of a side wall and a bottom plate. CONSTITUTION:An upper plate 1 is formed with gas injection holes 6, a side wall 2 is formed as a cylindrical body with several gas injection holes 7 being made in a flat plate and it is connected with a coupler part 8 at the upper part 1. The side wall 2 is provided with a mixing pipe 13 and a bottom part 3 is fitted to the cylindrical body so as to complete an assembly of the burner. Since a diameter of each of the gas injection holes 6 and 7 is made to have a size of 1.1mm or less, for example, the flame length is short and uniform, resulting in providing a superior efficiency of combustion. Further, since a size of the gas injection hole is small, the flame is hard to make a back-fire. Further, since a volume of gas chamber 12 is small, the remained gas is low in its volume and so no sound of diminishing of flame is generated.

Abstract: PURPOSE:To reduce leak currents and to improve memory keeping characteristic by forming a polycrystalline silicon layer, thermally oxidizing it in an oxide atmosphere containing fluorine or compounds thereof, removing such thermally oxidized film by etching, and then forming a desired insulating film on the polycrystalline silicon layer. CONSTITUTION:The surface of a polysilicon film 8 formed on an oxide film is characterized by irregularities 20 due to an infinity of crystal grains, in the interior of which crystal grains 21 are present. When oxidizing the polysilicon film 8 in oxygen containing NF3, large quantities of fluorine atoms 23, being entrapped by an oxide film formed on the polysilicon film 8, plasticity of the oxide film 22 increases while stresses are relieved. By this reaction, the surface of the n<+>-type polysilicon film 8 is smoothly oxidized. At the same time, fluorine atoms 23 are infiltrating into the n<+>-type polysilicon film 8 and combined with non-combined Si atoms which are present at the boundary of the crystal grains 21. As a result, doner type impurities in the n<+>-type polysilicon film 8 are no longer precipitated at the boundary of the crystal grains. According to the constitution, the characteristic of a capacitor oxide film to be later formed can be improved. By removing the oxide film 22 by etching afterwards, an excellent film can be obtained.

Title: Manufacture of semiconductor device
Inventor: ARAI KEITA
IPC: H01L21/28
Filed: 1991-09-18
Abstract: PURPOSE:To obtain a semiconductor device provided with a thin film silicon carbide layer having excellent crystallinity and formed on a silicon substrate 2 and elements formed on the silicon carbide layer. CONSTITUTION:After a silicon oxide layer 4 is formed on a semiconductor substrate 2, openings 14 are formed through the layer 4. In the openings 14, silicon carbide crystal layers 16 are grown until the layers 16 come to cover parts of the abovementioned insulating film. Then thin film silicon carbide layers are obtained by applying SOG to the entire surfaces of the layers 16 and performing anisotropic etching. After obtaining the thin film silicon carbide layers, elements are formed in the layers. When the elements are formed in the laterally-grown silicon carbide crystal layers in such way, a semiconductor device having an excellent electric characteristic can be obtained, since the laterally-grown silicon carbide crystal layers have a uniform plane orientation.

Abstract: PURPOSE:To manufacture a semiconductor device having a good characteristic with the small number of processes by a method wherein a low-melting-point glass layer is melted by a heat treatment, an insulating layer is formed around a polysilicon layer and an impurity inside the low-melting-point glass layer is diffused into a substrate in order to form a diffusion region of low impurity concentration which is interlinked with a source region and a drain region of high impurity concentration. CONSTITUTION:A gate oxide film 11, a polysilicon layer 12 and a low-melting-point layer, e.g., a phosphate glass layer 13, are laminated in succession on a p-type silicon substrate 10. Then, only the phospho-glass layer 13 is removed selectively by an anisotropic etching operation. After that, the polysilicon layer 12 under it is removed selectively by a quasi-isotropic etching operation of a high selective rate. At this stage, ions of an impurity are implanted by making use of the phosphate glass layer 13 as a mask; a source region 14 and a drain region 151 (n<+> diffusion regions) of high impurity concentration are formed. Then, if the phospho-glass layer 13 is melted by a heat treatment, an insulating layer is formed around the polysilicon layer 12 functioning as a gate; phosphorus inside the glass layer 13 is diffused into the substrate 10; a source region 142 and a drain region 152 (n regions) of low impurity concentration are formed.

Title: Evaluation for dispersibility of carbon-black
Inventor: HIRAI SUSUMU
IPC: G01N33/00
Filed: 1984-11-12
Abstract: PURPOSE:To decide on the propriety of dispersibility of carbon black easily and at a high accuracy, by a method wherein a proper amount of carbon black is mixed into water or a non-volatile hydrocarbon liquid at the normal temperature and the mixture is heated as a whole near the boiling point of water or hydrocarbon to cause a convection. CONSTITUTION:A proper amount, for example, about 0.1-10wt%, of carbon black is mixed into water or non-volatile hydrocarbon liquid at the normal temperature and then, the mixture is heated near the boiling point of water or hydrocarbon to cause a violent convection. In the flow of the liquid, the dispersion of the carbon black is examined to decide it as parameter of dispersibility for the polymer such as rubber and resin. In the evaluation on the state of dispersion of carbon black in the convecting liquid, generally, a method of deciding on the propriety of the degree of diffusion by visual observation from outside is used. But quantitative evaluation is possible by examining the number of particles per unit volume in terms of the particle diameter of the carbon black from the side of a transparent container.

Filed: 1999-08-25
Abstract: PROBLEM TO BE SOLVED: To perform the separation of a highly concentrated solution with high efficiency at the time of applying a reverse osmosis membrane at a high pressure by using a combined membrane formed by forming a separation functional layer on a supporting membrane having a double layer structure of a layer with fine pore diameter and a layer with large pore diameter and controlling the operation pressure to equal to or above a specific value to treat water. SOLUTION: As for a separation membrane, that is, a membrane having a fine pore layer or a combined membrane formed by using the same as a supporting membrane, a layer 4 is set to be thick. In such a case, there is the case that a separation functional layer 1, a fine porous supporting membrane 2 or the boundary thereof are not clear or the case that the distinction or the boundary of the layer 4 and a layer with >=200 nm void (circular opening) 5 is hardly distinguished because a base material component of the separation functional layer 1 enters sometimes the fine porous supporting membrane. The thickness of the layer in which the fine pores having >=200 nm fine pore diameter exist, is preferably <=80% of the whole thickness.  Further, though the combined membrane can be used at about 10 atm operation pressure, pressure resistant effect and a high permeation rate attained in the case of being used at >=50 atm.

Title: Wiper driving device
Inventor: MORI YASUSHI
IPC: B60S1/06
Filed: 1999-08-25
Abstract: PROBLEM TO BE SOLVED: To prevent driving to a front wiper when starting an engine after stopping the engine in an intermittent driving state of the front wiper. SOLUTION: In this wiper driving device, when a (first) turning-on operation is applied to an INT switch 5 with a front wiper switch set at an 'OFF' position, transistors TR2, TR4, TR3, TR5 are turned on, and that state is maintained to intermittently drive a front wiper even if the turning-on operation of the switch 5 is released. The switch 5 is a momentary switch, and returns to a turning-off position when the turning-on operation is released. When starting an engine after stopping the engine in the intermittent driving state of the front wiper, the front wiper is not driven because the switch 5 returns to the turning-off position after the first turning-on operation of the switch 5.
