Title: Manufacture of field-effect transistor
Inventor: BAN YUZABURO
IPC: H01L29/812
Filed: 1987-06-22
Abstract: PURPOSE:To accelerate the operation speed of a FET by a method wherein, at the time of the epitaxial growth of a semiconductor layer to be selectively doped, the surface of a substrate is irradiated with light simultaneously with the start of feeding the impurity material to rapidly increase the concentration of the impurities at the interface between the selectively doped layer and an undoped layer, with increased concentration of two-dimensional electron gas. CONSTITUTION:At the time of the epitaxial growth of a semiconductor layer to be selectively doped, the surface of a substrate is irradiated with light simultaneously with the start of feeding the impurity material. For example, when an AlGaAs/GaAs system HEMT structure is epitaxially grown with organic metal thermal decomposition vapor phase method, and with Al(CH3)3, Ga(CH3)3, AsH3 as the source material for Al, Ga, As; Si(CH3)4 as n-type impurity material; and H2 as a carrier gas, an undoped GaAs layer 2 and a non-doped AlxGa1-xAs layer 3 are grown on a semiconductive GaAs substrate 1. In addition to the source material of Al, Ga, and As, the surface of the substrate is irradiated with ArF excimer laser ray 5 simultaneously with the start of feeding n-type impurity material to grow an n-type AlxGa1-xAs layer 4.

Title: Ink jet recorder
Inventor: TAKEKOSHI NOBUHIKO
IPC: B41J13/076
Filed: 1990-06-13
Abstract: PURPOSE:To prevent effectively an occurrence of a curl of a material to be recorded regardless of the type of the material to be recorded even when a large quantity of striking ink is used for images by providing means for enforcing the material to be recorded to have projecting and recessed cross section in the direction approximately perpendicular to the conveying direction of the material at the time of delivery of the material after recording, and controlling the enforcing means according to the type of the material to be recorded. CONSTITUTION:A material to be recorded 23 on which an image is recorded at a record head is delivered while being enforced to have a projecting and recessed cross section in the direction perpendicular to the conveying direction. Such an enforcement is performed by delivering the material to be recorded 23 to a tray 27 through a roller 30 consisting of paper delivery upper rollers in tandem 28 and paper delivery lower rollers in tandem 29 arranged in staggered form in the direction of paper width. It is enforced to have projecting and recessed cross section in the direction perpendicular to the conveying direction even when a curl is to be formed with a recording face outside due to striking with a large quantity of ink and expansion of the recording face.

Title: Photoregenerable lith-type developing solution made of iron complex
Inventor: SHIRAI YASUO
IPC: G03C5/30
Filed: 1980-11-04
Abstract: PURPOSE:To obtain a photoregenerable lith-type developing solution, by adding a ferrous salt and an organic acid, and EDTA. CONSTITUTION:The lith-type developing solution to be used contains a ferrous salt, as a principal developing agent, an organic acid having >=2 carboxyl groups, as a chelating agent, and EDTA in a molar ratio of the ferrous salt: the organic acid and EDTA of 1:0.6-1.2. When the molar concentration of the organic acid is higher than that of EDTA, the gamma value increases, but development power decreases. When pH is 6.5-8.0 and KBr is added to 1-3g/liter, fog is suppressed even when pH is >=8. When the developer is fatigued by oxidation, it is regenerated by irradiation of a mercury lamp for 10-30min, while gaseous nitrogen prevents oxidation. Addition of a small amount of the organic acid and EDTA accelerates photooxidation of the ferric salt, therefore its regeneration.

Title: Boot loading system
Inventor: IWATA YASUNOBU
IPC: G06F13/00
Filed: 1987-06-22
Abstract: PURPOSE:To simply change a program or the number of loading sheets of an external auxiliary memory part by using a loading designation file to instruct the start of the program to be loaded or a system. CONSTITUTION:A CPU 1 starts a boot loading program stored in a ROM 3 when a power source is turned on or reset. In this case, a floppy disk containing a loading designation file shown in a figure (a) is put into a floppy disk deice 5. A boot loading program is started and reads a loading designation file 12 onto a memory. Then it is decided by data 15 whether a file to be loaded exist or not. If so, the relevant file is loaded. This step is repeated after the floppy disk is exchanged with the one shown in a figure (b). Finally the floppy disk is exchanged with the one shown in a figure (c) and a start instruction is produced. Then a boot loading system is started when coincidence is secured between the designated number of sheets stored in the file 12 and the counted number of sheets.

Filed: 1979-11-29
Abstract: PURPOSE: To eliminate pollutional problems by preventing the elution of metallic zinc from a zinc coating by forming a seal coat layer by drying a phenoxy resin solution applied onto the surface of the zinc coating.  
     CONSTITUTION: Onto the zinc coating surface, a solution obtained by solving the phenoxy resin of about 10,000W50,000 mean molecular weight, consisting essentially of epichlorohydrin and bisphenol A, in an organic solvent such as methyl ethyl ketone is applied by the ordinary method to about 5W50μm dry film thickness and then dried by scattering the solvent by leaving it at the normal temperature or by a hot blast, forming a seal coat layer. Thus, many process required for the conventional secondary coating, etc., can be made unnecessary and the elution of metallic zinc from the zinc coating can be prevented.

IPC: B01D63/10
Filed: 1987-06-22
Abstract: PURPOSE:To prevent the clogging of a raw water passage and the collapse of the separation membrane at the time of winding by providing a spacer consisting of first linear materials extending in one direction and parallel to each other and second linear materials crossing the first material and extending in another direction in the bag-shaped separation membrane. CONSTITUTION:The first linear materials 2a parallel to the axis of a water collecting pipe 1 and the second linear materials 2b orthogonal to the first material 2a and parallel to each other are arranged in parallel crosses, and bonded to form the spacer 2. The bag-shaped separation membrane 3 contg. the spacer 2 is wound on the water collecting pipe 1 without interposing any passage material between the separation membranes 3, and a raw water passage is formed between the separation membranes 3. Since any passage material is not present in the raw water passage, the clogging of the raw water passage due to the adhesion of suspended matter to the passage material is not caused. When raw water is supplied in the raw water passage, the separation membrane 3 is pressed on the spacer 2, ruggednesses are formed along the membrane surfaces of the linear materials 2a and 2b, the flow is disturbed, and the concn. polarization is eliminated.

Title: Apparatus for controlling supply of hot water
Inventor: NAGAOKA YUKIO
IPC: F23N1/08
Filed: 1982-09-06
Abstract: PURPOSE:To control the temperature of hot water supplied to be equal to a set temperature against rapid temperature change of hot water, by controlling the heating power of a heating means and the flow rate of by-pass water. CONSTITUTION:Hot water heated at a heating means 24 and cold water in a by- pass passage 15 are mixed at a mixing section 16, and the temperature of the mixed water is detected by a means 17 for detecting the temperature of supplied hot water. In case that the flow rate of water is reduced drastically, the temperature of hot water is raised rapidly since the flow rate of water to a heat exchanger 13 and the by-pass passage 15 is reduced. In such a case, heating power of the heating means 24 is reduced rapidly by detecting the temperature rise of hot water by said means 17 and controlling a heating power controller 23. At the same time, rapid temperature rise of hot water at the mixing section 16 is prevented by increasing the opening of a water flow control valve 11 and thereby increasing the flow rate of water through the by-pass passage 15.
