Patent JP-H09266423-A (JP)
Title: Power amplifier
Inventor: MEJIKA KENICHI
IPC: H03K17/30
Filed: 1996-03-28
Abstract: PROBLEM TO BE SOLVED: To provide the power amplifier which is simple in constitution, easily made small-sized, and inexpensive and small in power loss. SOLUTION: A voltage error signal EVA is generated by comparing the voltage at a terminal 22R of an error amplification part 22 based upon the voltage at the power supply terminal 50A of an amplifier 50 with the voltage at a terminal 22S based upon the output signal Sout of the amplification part 50. The oscillation signal FS from a reference oscillation circuit 52 is supplied to a pulse control circuit 23. When the voltage at the terminal 22S rises above that at the terminal 22RR, a control circuit 23 generates a driving signal SWA by varying a duty ratio equally to the signal FS and on the basis of the signal EVA, thereby driving an FET 12. A source voltage +VIN is raised corresponding to the signal SOUT and supplied to the terminal 50A. Similarly, a source voltage -VIN is boosted corresponding to the signal Sout and supplied to a power supply terminal 50B.  It is not necessary to generates a high and a low source voltage and switch them according to the signal SOOUT, the constitution is simple and small-sized, and also inexpensive, and the power loss is reducible.

Title: Dc-dc converter
Inventor: KOBAYASHI KAZUO
IPC: H02M3/28
Filed: 1980-06-04
Abstract: PURPOSE:To detect faults in DC-DC converters at a low cost by controlling the pulse width by using the predetermined potential value of a clamped main output voltage wherein the pulse width is prevented from zero at no load. CONSTITUTION:The outputs of two DC-DC converters are commonly connected to couple with a load RL. At the secondary sides of transformers, T1, T2 smoothing circuits composing of resistors R1, R2, and a capacitor C2 are provided at the output sides of auxiliary rectifiers 7, 8 provided apart from main rectifiers and the dividing points of main output voltages V0 and the output of the smoothing circuits (the connecting point of R1 an R2) are connected by diodes D1, D2. And mean value rectification can be attained when the pulse width is below a fixed value by properly selecting the time constant of the smoothing circuits. Therefore, the output voltages V1 of the smoothing circuits reduce when the load decreases and the dividing voltage V2 at the output voltages V0 is clamped by the diodes D1, D2. So, control amplifiers 3, 4 control inverters 1, 2, to broaden the pulse width. Therefore, faults in the converters can be detected by detecting means 9, 10 for stopping the inverters.

Filed: 1990-03-26
Abstract: PURPOSE:To perform specific analysis and detection with high sensitivity by a relatively small-sized light apparatus by dissolving the narcotics contained in sample air bonded and adsorbed on a filter to mix the same with an antibody and identifying the narcotics by antigen-antibody reaction. CONSTITUTION:Narcotics such as methamphetamine contained in sample air are bonded to or adsorbed on a polyether sulfone filter having a pore size of about 0.45 mum and dissolved in a phosphate buffer solution with pH of about 0.7 to obtain a sample solution. Next, bovine serum albumin is bonded by a known method and a mouse is immunized with this antigen for about 5 weeks to obtain a polyclonal antibody from serum and the spleen of the mouse and a cancerous cell are fused to obtain a highly reliable monoclonal antibody from the polyclonal antibody. The antibody solution and the sample solution are mixed and the advance degree of antigent-antibody reaction is analyzed and detected on the basis of the change of the fluorescence intensity of the antibody itself. By this method, the presence and amount of the narcotics contained in sample air can be identified.

IPC: H04B10/00
Filed: 1980-06-06
Abstract: PURPOSE:To increase the reliability of an optical repeater, by suppressing the output of the beam of a semiconductor laser by the function of a control circuit when the optical input level of the supplied optical time series digital information is less than a prescribed value and then actuating slowly the control circuit. CONSTITUTION:In case the optical level of the optical information supplied to an optical repeater 1 is less than the optical level which is necessary for the normal working of the repeater 1, a specific control signal affects a logical circuit 21 to prevent the electric information obtained from an identifying circuit 9 from being supplied to a driving circuit 10. At the same time, a control circuit 22 suppresses forcibly the bias current of a semiconductor laser 11 down to almost zero to a stabilizing circuit 12 that holds the optical output level of the laser 11 to avoid an output of the optical information from the laser 11. Furthermore, these functions are given gradually within a range less than the time required for switching of an optical switch and with a time constant larger enough than the time constant at the interstage coupling part of an amplifying circuit.

Title: Method and apparatus for preventing reverse warpage in strain removing work of outside plates for vehicles
Inventor: KUBOTA OSAMU
IPC: B21D1/12
Filed: 1978-06-26
Abstract: PURPOSE: To prevent the occurrence of overall deformations in outside plates or deformations of contour etc. after strain removing work by giving a fixed deflection to the strain removing part of the outside plate and heating and cooling this deflected part thereby removing strain in removing the strain of the thin outside plate of vehicles, etc.  
     CONSTITUTION: The restraining devices 3 are pushed onto an outside plate 1 and  air between rubber pads 4 and the outside plate 1 is extracted to allow these to contact closely. Next, an angle is given by angle-adjusting cylinders 6 to the restraining devices 3 in such a manner that their respectively opposing sides float like the arrows, whereby moment is given to the portions of the outside plate 1 where the restraining devices 3 tightly contact. This gives a deflection to the intermediate part of the outside plate 1 opposing to the restraining devices 3. When this deflected portion is heated with a heating device 7 and is then cooled, the deflected portion shrinks, thereby permitting strain removal.
