Title: Heat exchanger
Inventor: SAWADA MASANORI
IPC: G21F9/02
Filed: 1999-04-22
Abstract: PROBLEM TO BE SOLVED: To provide a heat exchanger with a simple structure, manufacturable at a low cost, easy to maintain, and allowing prevention of degradation of performance and reduction of a service life caused by generation of a problem in heat transfer pipes. SOLUTION: This heat exchanger basically has a long passage for a high- temperature gas and spiral baffle plates 41 for increasing a heat exchange time, in a gap 40 between a middle cylindrical body 21 and an outer cylindrical body 22 of a double cylinder assembly, while the inner face of an inner cylindrical body 20, the outer face of the outer cylindrical body 22, and the inside of the baffle plates 41 are water-cooled. The high-temperature gas flowing from the upstream side flows downward along the spiral baffle plates 41 within the cylinder assembly, contacts with the outer cylindrical body 22, the middle cylindrical body 21 and the baffle plates 41 to be cooled below the dew point to separate water vapor as water drops. Thereby, effective heat exchange can be executed, a structure can be simplified, performance and a service life can be maintained, and safety can be secured.

Title: Device and method for controlling lamp illuminance, and color thermal printer
Inventor: MIYAZAKI NOBUO
IPC: H01J61/52
Filed: 1999-04-22
Abstract: PROBLEM TO BE SOLVED: To keep the illuminance of a bar-like lamp in the axial direction uniform. SOLUTION: This device is provided with cooling fans 35a-35c toward both end parts and the center part of a bar-like ultraviolet lamp 31. The illuminance of the ultraviolet lamp 31 is measured by illuminance sensors 37a, 37b at both end parts 31a, 31b. The illuinances measured by the illuminance sensors 37a, 37b are compared. The cooling fans at the end parts and the center part of the lower illuminance side are driven so as to cool the ultraviolet lamp 31. According to the cooling operation of the pipe wall, the light emitting amount is increased so that the illuminance difference with respect to the end parts at the higher illuminance side is made smaller. The illuminance distribution of the ultraviolet lamp 31 in the axial direction becomes substantially uniform.  Since both end parts with a low illuminance can also be utilized effectively, the device size can be made smaller by that.

Inventor: YASUKAWA SHIYOUHEI
IPC: D06F58/00
Filed: 1977-09-26
Abstract: PURPOSE: To improve a handling efficiency for the objects to be dried, by fitting swingably condensing plates by means of hinges, by pressedly contacting the objected to be dried between the condensing plates and the heat plates, and by minimizing a contact resistance between the heat plates and the objects to be dried in such a way that they are kept in the condition as it is at the time when the condensing plates open.  
     CONSTITUTION: Condensing plates 13a and 13b are loose-fitted in long holes 21 of hinge metals 19 and 20, whose hinge axles are fixedly fitted at a frame 4, and are fitted swingably toward heat plates 1 and 2 by means of the hinges. Since spring hooks 28a and 28b are placed in outer position than the hinge axles, the condensing plates 13a and 13b are kept in a steady position the way the condensing plates open, by means of pressing springs 29, thus, the objects to be dried can be set and removed easily. In the case of the condensing plates 13a and 13b being closed, the pressure of the pressing springs 29 acts altogether effectively as a pressing force, because the hinge axles 18 are loose-fitted in the long holes 21, and clamp springs 33 also acts as the pressing force, thus, the objects 24 and 25 to be dried come in pressure-contact with the heat plates 1 and 2

Title: Reproduction synchronization device
Inventor: MAEDA TETSUO
IPC: G10K15/04
Filed: 1997-05-02
Abstract: PROBLEM TO BE SOLVED: To avoid the failure of synchronous reproduction with a necessary sound by predicting a time required for decoding respective frames, abolishing a frame decoding processing when the decoding processing cannot be displayed in time with a video content and repetitively displaying a previous frame video. SOLUTION: A decoding time prediction part 102 predicts the decoding time of encoding video data and outputs decoding termination prediction time. When the prediction time is delayed from the generation time of a synchronizing signal, which corresponds to the determined display time of pertinent encoding video data, a thinning signal generation part 103 generates a thinning signal 203. A data supply part 104 supplies encoding video data to a buffer memory 105 when the generation of a digital video signal terminates or when the thinning signal 203 is inputted. A video generation part 106 stops a video generation processing during progress by inputting the thinning signal 203 and starts the generation of the next data video.  A display memory 107 temporarily accumulates the digital video signal and a video output part 108 outputs the digital video signal of the display memory 107 as the video signal by a synchronizing signal.

Abstract: PURPOSE: To easily improve cleaning effect in AC TIG welding by providing rectifier elements respectively between the two secondary windings provided to a single phase transformer for welding and a welding load, and providing a difference in the number of turns of the secondary windings.  
     CONSTITUTION: The respective numbers of turns of the secondary windings 10a, 10b of a leakage transformer 10 are defined as N 1 , N 2 , impedances as Z 1 , Z 2  and no-load voltages as E 1 , E 2 . When set N 1 >N 2 , there is obtained Z 1 >Z 2  and the secondary short-circuiting currents of the windings 10a, 10b go E 1 /Z 1 , and E 2 /Z 2 . Namely, when the tungsten electode of a welding torch 13 in which electric current is intrinsically difficult to flow is positive and the welding load is negative, the impedances of the windings are small and therefore they act flow more currents. When the tungsten electrode in which electric current is easy to flow the is negative and the welding load is positive, the impedances of the windings are large and therefore they act so as to suppress the flowing currents. Hence, The DC component of the AC TIG welding current is reduced and sufficient cleaning effect is accomplished.

Filed: 1993-05-18
Abstract: PURPOSE:To stabilize releasing operation, miniaturize a device, and reduce cost by allowing a constant voltage element to achieve the flow of an excitating current to a coil when the charge voltage of a smoothing capacitor exceeds a specific voltage. CONSTITUTION:Inrush current flowing to a primary DC power supply circuit 10 when a switching switch 2 is turned on is suppressed by a resistor 52 for limiting current of an inrush current suppression circuit 50. Then, when the charge voltage of a capacitor C1 for smoothing reaches a specific voltage, a constant-voltage element Z61 of a suppression operation releasing circuit 60 continues, thus exciting a coil 54 via a resistor R61 and turning on a disconnecting switch 53 and then short-circuiting the resistor 52 for limiting current. Therefore, the releasing point of suppression operation of the inrush current suppression circuit 50 can be made constant and at the same time cost can be reduced and the device can be miniaturized since the configuration is simple and the number of components is small.
