Title: Cooling structure for power supply unit
Inventor: ISHIKAWA HIROYUKI
IPC: H02B1/56
Filed: 1999-03-26
Abstract: PROBLEM TO BE SOLVED: To prevent power supply performance from being degraded even if a power supply unit is used even in adverse environments by disposing it so as to face the inner space of a radiating pipe, introducing outside air into the inner space of the radiating pipe from one end thereof, and mounting an outside air introducing/discharging means for discharging the outside air from the other end thereof. SOLUTION: The cooling mechanism of an electronic circuit element in a power supply unit is formed out of a radiating pipe 2 and an outside air introducing/discharging means 3, so that heat generating the electronic circuit element may be lost by outside air passing through the radiating pipe 2 (without stopping in the electric supply unit) through the radiating pipe. Therefore, the outside air is prevented from entering the electric supply unit, more specifically, a space in which the electronic circuit element exists. Even if the electric supply unit is used in adverse environments, and the outside air includes toxic substances such as metal powder and oil mist, they are not introduced into the electric supply unit substantially.  It is thus possible to prevent the electronic circuit element from being degenerated by the toxic substances in the outside air, thereby preventing electric power performance from being degraded.

Title: Paper transport apparatus of copying machine
Inventor: UCHIUMI KATSUROU
IPC: B65H15/00
Filed: 1984-04-27
Abstract: PURPOSE:To improve of efficiency of copying operation by providing a turning mechanism for turning either a sheet copied at the time of outward-scanning a document or a sheet copied at the time of return-scanning a document to discharge sheets in the uniform direction from a copying machine. CONSTITUTION:A sheet 2' guided to a branch path 4 at a gate 6 is brought into contact with a stopper 12 projected in the branch path 4 and stopped. On detecting that the sheet is stopped, an electric current is applied to a solenoid 16 to project a pivot 13 into the branch path 4. The forward end of the pivot 13 presses the center of the sheet 2' on a base plate 4a, and simultaneously the stopper 12 is retreated by a solenoid 15, so that the sheet 2' is turned around the pivot 13 by a transport roll 14. When the sheet 2' is turned in a 180 deg. arc, the pivot 13 retreats from the branch path 4, so that the sheet 2' is fed out from the branch path 4 at the turned position by the transport roll 14 and discharged to a paper discharge tray. One 2' of the sheets 2, 2' carried in the opposite directions is turned in a 180 deg., so that both sheets are discharged in the uniform direction.

Title: Paper clogging detector
Inventor: WATANABE KOUJI
IPC: B65H7/06
Filed: 1979-06-29
Abstract: PURPOSE: To prevent any malfunction in jam detection from occuring by deciding it to be a normal state if a beginning end memory is in a storage state when a detecting timer is outputted in a fixed time after cutting of the final end of recording paper and deciding it to be jam when it is in a nonstorage state.  
     CONSTITUTION: When recording paper 11 is subjected to developing and fixing treatment and its beginning end reaches a switch 21, its arrival is stored in a beginning end reaches a switch 21, its arrival is stored in a beginning end memory 31. When the final end of the recording paper 11 reaches a cutter 15 after a little time and is cut, the cutter signal causes a detecting timer 34 to start clocking and generate an output after a predetermined time. If the beginning end memory 31 is in a storage state when this detecting timer 34 is outputted, it is regarded to be normal and in succession, the beginning end memory and the detecting timer 34 are reset by the output of a reset timer 36. If the beginning end memory 31 is in a nonstorage state when the detecting timer 34 is outputted, it is regarded to be jam and the output of the reset timer 36 is blocked to stop various operations. In this way, the jam detection may be done surely.

Title: Heat exchanger
Inventor: AKUTAGAWA RYUTARO
IPC: F28D7/00
Filed: 1985-04-19
Abstract: PURPOSE:To improve the heat transfer performance of the heat exchanger by inserting the group of fine tubes between flat tubes so that the group of fine tubes is contacted with the outer walls of flat tubes. CONSTITUTION:The flow path of fluid A is made by a rectangular tube and the fine tube 1 is made by a circular tube. When this heat exchanger is compared with the same having fins, whose pitch is same as the diameter of the fine tube 1, heat transfer area per unit length in the flow direction of the fluid B becomes about three times in this case, therefore, the size of the heat exchanger, capable of securing the same heat transfer area as before, may be compacted while heat transmitting coefficient becomes better in case the circular tube is employed since the equivalent diameter in the case of circular tube becomes half of a parallel flat plate model. Accordingly, the heat transfer area may be increased, works for making fin may become unnecessary and the heat transfer performance may be improved.

Abstract: PURPOSE:To obtain a VTR in which the after-recording function of a voice signal is realized by using a rotary head, by providing a means which records another voice signal shallower than a magnetized area by a video signal on the surface layer part of a magnetic tape. CONSTITUTION:The voice signal inputted from an input terminal 1, after the micro level component of which being enhanced at a noise reduction circuit 2 and the high frequency component of which being enhanced at a pre-emphasis circuit 3, is changed to a signal to be FM-modulated at an FM modulation circuit 4. Afterwards, a signal of desired band is extracted at a BPF5, and is amplified at a recording amplifier 6. Meanwhile, as for an inputted video signal, the luminance signal component of the signal is extracted at an LPF12, and after it is changed to the signal to be FM-modulated at a luminance recording process circuit 13, the component of the band superposed on a low frequency conversion chromaticity signal is eliminated at an HPF14, then, the signal is added on an adder 15. In such a way, it is possible to perform the after- recording of the voice signal on the recording track of the video signal and the voice signal, and to reproduce the voice signal recorded simultaneously with the video signal and an after-recorded voice signal selectively.

Filed: 1989-04-04
Abstract: PURPOSE:To facilitate a work by inclining a receiving magazine which is loaded in a horizontal state so that its leading edge may become lower with the aid of an operating start manipulation and then restoring it to the horizontal state. CONSTITUTION:When an operation start button 2b in a manipulation part 2 is depressed, a motor 12 starts to rotate and a cam plate 13 is turned. Then, a reception box 11 begins to ascend through a roller 11a and a motor 12 is stopped by turning on an upper position sensor 14b. Since the receiving magazine 10 takes an upper position to be inclined, the leading edges of the housed films in various sizes are arranged and, at the same time, a sucker 15 moves and a conveying roller 17 starts to turn. When all the films are drawn out and conveyed from the magazine 10, the conveying roller 17 stops and the motor 12 starts to reversely rotate. Then, the reception box 11 descends because the cam plate 13 rotates in a reverse direction to the time when it ascends and the reverse rotation of the motor 12 is stopped by turning on a lower position detecting sensor 14a. Thus, the work for arranging the leading edges of the films are automatically performed.
