Title: Magnetron driver device
Inventor: NARITA TAKAYASU
IPC: H01J23/34
Filed: 1987-12-15
Abstract: PURPOSE:To supply constant heater voltage to the heater of a magnetron from a heater winding by interposing a magnetic leak means with a gap between a core, on which the primary and secondary windings of a transformer are wound, and a core on which the heater winding is wound, and by winding the heater winding in the position facing the primary and secondary windings. CONSTITUTION:A heater winding 52C is wound on an asymmetrical E-shaped core 52d1 arranged oppositely through a gap AG, and a secondary winding 52b is wound on the other core 52d2 followed by parallely winding of a primary winding 52a. Because leak flux is generated in the gap AG, the magnetic bond of the heater winding 52c with the primary and secondary windings 52a, 52b, particularly with the primary. Regardless of varying input voltage, the rate of change in the heater winding voltage Ef is less. Therefore, the voltage induced in the heater winding 52 is approx. constant with varying input power P to the magnetron, which enables stable supply of the heating power to the filament.

Title: Method for determination of mite antigen in indoor dust
Inventor: NAGATA KENJI
IPC: C12P21/08
Filed: 1988-12-15
Abstract: PURPOSE:To exactly determine only the specific mites and to determine even the allergic factors, such as broken pieces and excrements of mites, which are important in medical fields by applying a monoclonal antibody for antigen determination of the mites in the indoor dust. CONSTITUTION:An ELISA method is used for its ease of techniques and high detection sensitivity in order to apply the monoclonal antibody to the antigen determination of the mites in the indoor dust. The monoclonal antibodies are screened on the basis that the antibody reacts only with the target mite and does not react with the other mites or reacts just slightly therewith to precisely select the candidate in the selection of the monoclonal antibody. Particularly the establishment of the determination system for the house-dust mites is desired and, therefore the monoclonal antibodies which react approximately equally with the KONA-house-dust mite the YAKE-house-dust mite are selected by screening. The antibody having the lowest reactivity with the mold mites among these antibodies is adopted.

Title: Voltage follower circuit
Inventor: NISHIMURA KOICHI
IPC: H03F3/50
Filed: 1988-12-14
Abstract: PURPOSE:To set the offset voltage at zero by detecting the difference of the base-emitter voltage between an NPN TR and PNP TR and correcting the detected voltage difference at the input side. CONSTITUTION:A 1st NPN TR Q1 and a 4th PNP TR Q4 serve as an input buffer and an output buffers respectively. A 1st resistance R1 corrects the difference of the base-emitter voltage VBE caused between both TR Q1 and Q4. The NPN TR Q2 and Q3 and a 2nd resistance R2 function to supply a correction current to the resistance R1. Then a start-up circuit 5 is added. The difference of voltage VBE between base and emitter is detected. The detected difference of VBE is once converted into a current via the R2. This current is converted again into the voltage via the R1 connected in series to the TR Q1. Thus the difference of VBE is cancelled and no offset voltage is produced.
