IPC: H01F19/04
Filed: 1984-06-20
Abstract: PURPOSE:To provide a miniaturized and low-cost impedance transformer by a method wherein the length of coaxial lines is selected so as to correspond to one fourth wave length of an operating cener frequency, and outside conductors of the plural numbers of coaxial lines which have the same characteristic impedance are grounded and their core conductors are connected in parallel at each end thereof and is designated as an input-output terminal. CONSTITUTION:Coaxial lines 31, 32, 33 have the same impedance ZT respectively and line length corresponds to one fourth wave length of operating central frequency. If impedance, whose reference impedance is Zo, is connected to an input terminal 34 and impedance looked from output terminal 35 is Zout, Zout=ZTE<2>/Zo=Zr<2>/9Zo. Zo is an impedance in a measurement device and is normally 50OMEGA. ZT is 75OMEGA, 50OMEGA, 25OMEGA, etc. which is able to obtain easily as standard products and also is very low-cost. If Zo=50OMEGA is designated and is selected either one of 75OMEGA, 50OMEGAm 25OMEGA as a coaxial line, Zout becomes 12.5OMEGA, 5.56OMEGA, 1.39OMEGA and a transformer which is high impedance transformation ratio can be realized.

Title: Electronic clinical thermometer
Inventor: ITOU AYAO
IPC: G01K13/00
Filed: 1984-06-22
Abstract: PURPOSE:To simplify the circuit constitution by commonly operating a sensor, which detects bodily temperature, and an element, which drives a buzzer, by one transistor. CONSTITUTION:By the output of a control circuit 23, the collector and the emitter of a transistor Tr 22 are shorted. The base and the collector of a transistor Tr 1 are shorted. Under this state, the transistor Tr 1 starts temperature measurement. A temperature measuring circuit 24 amplifies a voltage cooresponding to the temperature, which is detected by the transistor Tr 1. The result is converted into the bodily temperature by an operation circuit 25. The temperature is added to a display driving circuit 26 and displayed on a display circuit 6. When a report is announced by a buzzer, a control pulse, which releases the shorted state of the transistor Tr 22, is sent from the control circuit 23. This operation is intermittenetly performed, and energy is stored in a coil 4. Thus a buzzer sound is generated by the resonance with a piezoelectric element 3.

Title: Pattern forming method of semiconductor device
Inventor: I TENCHIN
IPC: H01L21/302
Filed: 1996-05-23
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of pitting except in the photoresist in the edge section of a wafer by exposing the photoresist to nonpatterned blank light and successively exposing the photoresist in the effective area of the wafer in which a pattern is to be formed to patterned light, and then, removing the photoresist from the edge section. SOLUTION: The photoresist in the edge section 4 of a wafer is exposed to light by using a nonpatterned blank reticle, because no pattern is formed in the section 4. Then the photoresisit in the effective area 5 of the wafer where a pattern is to be formed is exposed to light by using a reticle having a prescribed pattern. When the exposed photoresist is developed by dipping the wafer in a developing solution, the exposed photoresist is removed. Namely, the photoresist is completely removed from the edge section 4 and only left in the effective area 5. Therefore, the occurrence of pitting can be prevented.
