SOLUTION: HVAF(high velocity air fuel) high speed flame spraying in which a thermal spraying material is placed on high temp.-high speed combustion flame by a thermal spraying gun 1 and is collided with a thermal spraying base material 6 in a melted or half-melted state, and YAG laser irradiation 51 in which this sprayed coating is melted is simultaneously executed in parallel, in the thermal spraying in the 1st pass, a YAG laser Lbc1 is simultaneously applied on the position in which high speed flame is formed, and on and after the 2nd pass, directly after the high speed flame spraying, a YAG laser Lbc2 is applied.  Before such thermal spraying, each distance of the plural points on the base material is measured by a laser range finder measuring head 5 carried by a thermal spraying gun carriage 2, the distance from the surface of the coating film is measured even in the process of the thermal spraying operation, the difference between it and that before the thermal spraying, i.e., the thickness of the sprayed coating film is calculated, and the fact whether or not it has reached the one equal to or above the objective value is judged. The head 5 is supported by an arm 32 and is revolvingly driven by 180 deg..

IPC: F24F1/02
Filed: 1980-06-27
Abstract: PURPOSE: To obtain a dehumidifying function which is simple in structure and accurate in operation by a method wherein a convex-concave cooling section adopted to exchange heat between air inside the room and that outside the room is provided in an outer casing of the captioned fan attached with the dehumidifier for humidifying the air inside the room by cooling the same with the open air.  
     CONSTITUTION: When a switch turns ON in a state in which a guide plate 18 is rotated up to a solid line position shown in the drawing, an impeller 12 is rotated through a motor 13 so that damp air in the room A such as a bath room is sucked into an outer casing 1 via a sucking port 3  and circulates through a vent passage C. During the above operation, the damp air comes into  contact with cooling fins 14 and 15 and is cooled as a result of its heat exchange with the low  temperature open air in a region B outside the room so that the moisture content in the air is transformed into dew drops which fall down on a float board 8 through a water plte 7 to be then discharged from a water exhaust port 6. The air dehumidified in the above manner is passed  through a casing 11 and is returned to the room A via an air outlet 11b and an air exhaust port  4. On the contrary, in case where the guide plate 18 is rotated up to a chain line position as  shown, the air in the room after humidification is discharged into the region B outside the room  through another air exhaust port 5.

Title: Dynamic change mechanism for starting directory in interactive shell
Inventor: ISHII ATSUSHI
IPC: G06F15/00
Filed: 1991-04-19
Abstract: PURPOSE:To make it unnecessary to be conscious of a directory to be executed and to easily execute operation by dynamically changing a command execution directory in an interactive shell to be driven in an environment having hierarchical structure. CONSTITUTION:A directory determining part 6 and a directory changing part 7 are arranged between an interactive shell analyzing part 2 and an execution part 3. When a command is inputted, a parameter or the like for the command is analyzed. Whether the command is to be executed by a directory starting up the interactive shell or a displayed directory is discriminated. When the command is to be executed by the directory starting up the interactive shell, the displayed directory is moved to the directory starting up the shell, and finally the command is executed. Since the starting directory is automatically changed, it is unnecessary to be conscious of an execution directory.

Title: Powder ink
Inventor: SHIMURA EIJI
IPC: B41M5/392
Filed: 1989-04-08
Abstract: PURPOSE:To improve repeating characteristics by eliminating the thickness irregularity and surface unevenness of the ink layer of a regenerated ink sheet by externally adding carbon black to the surface of the matrix particle of a powder ink in a specific coating ratio to fix and embed the same to the matrix particle in a specific ratio of the particle size thereof. CONSTITUTION:Powder ink 11 is supplied to an ink sheet 1 in such a state that bias voltage Vb is applied between an electrode 10 and a conductive roller 12 from a power supply 13. The powder ink 11 brought into contact with the release part 8 of the ink layer of the ink sheet 1 receives the injection of charge in the quantity proportional to the product of the electrostatic capacity of an insulating support 2 and Vb because the release part 8 shows insulating properties to be adhered to the support 2 by electrostatic force. However, the adhesion part 9 of the ink layer and the powder ink 11 being in contact with the powder ink adhered to the support obtain no adhesive force because the ink layer and the powder ink are conductive. Since carbon black is externally added to the surface of the matrix particle of the powder ink in a coating ratio of 50% or more and 1/3 or less the particle size thereof is fixed to and embedded in the matrix particle, the adhesion of the powder ink to the adhesion part of the ink layer can be eliminated.

Title: Distributed feedback semiconductor laser with external resonator
Inventor: MURATA SHIGERU
IPC: H01S5/12
Filed: 1986-04-17
Abstract: PURPOSE:To obtain a light source having a narrow spectral line width and a controllable frequency by a method wherein an external resonator, wherein the refractive index of a partial region of the passive light waveguide is electrically designed variably and a distributed feedback (DFB) laser are integrated on the same semiconductor substrate. CONSTITUTION:Diffraction gratings of the prescribed period are formed in a DFB laser 100 on an N-type InP substrate 300, and an N-type InGaAsP light guide layer 310, an InGaAsP active layer 320 and a P-type InP clad layer 330 are epitaxially formed in order. Then, the layers 330 and 320 are selectively removed except the DFB laser part 100 and the whole is covered with a P-type InP clad layer 340. Then, a mesa etching is performed for conducting the embedding and growth and electrodes are each attached on the DFB laser part 100 and a phase control part 400. Moreover, the electrical insulation of each part is performed by providing an etching groove in parts of the growing layer. As a P-N junction is ready-formed in the guide layer 310, the refractive index of the phase control part 400 can be varied by injecting carriers into this part. Both end faces of an element are formed by performing a cleavage. If the injection current into the phase control part 400 is slightly changed, the frequency of the light source can be modulated leaving as the spectral line width is roughly constant.

Title: Controlling method of decompression device for engine
Inventor: MATSUKI IKUO
IPC: F02D13/08
Filed: 1984-05-07
Abstract: PURPOSE:To increase the output by releasing the decompression device at a low speed when starting, and to ensure an engine stop when decelerating by engaging the decompression at a high speed. CONSTITUTION:An arrangement is made such that a decompression cam 4 is actuated by a decompression weight 6, and an auxiliary weight 9 is disposed between and engageable with both the weights 6, 9 by a resilient hook 10. When starting, both the weights 6, 9 are connected by the hook 10, and so, a large centrifugal force is acting on them at a low speed. Therefore, the decompression is released at a relatively low speed, resulting in an increase of the engine output. Since the hook 10 separates the weights 6, 9 at normal operating speeds, the weight is reduced, causing a less centrifugal force at a relatively high speed, and so, the decompression is engaged under a deceleration mode at a relatively high speed to ensure the engine stoppage.
