Title: Impedance-measuring device for adjusting antenna
Inventor: OI KATSUMI
IPC: G01R27/06
Filed: 1996-05-09
Abstract: PROBLEM TO BE SOLVED: To directly observe a state of matching of impedance by connecting a measuring apparatus to an antenna power feed part or in the middle of a coaxial power feed line connecting an antenna and a communications device and indicating an impedance characteristic of an antenna system on a meter. SOLUTION: The measuring apparatus has a load display meter 3 and a reactance display meter 5. The load display meter 3 indicates whether an absolute value of an impedance to be measured is large or small to a reference impedance, in accordance with a direct current output from a load detection part 2. The reactance display meter 5 indicates a polarity of a reactance of the impedance to be measured and whether the reactance is large or small, in accordance with the direct current output from a phase detection part 4. Calibrated numerical scales are shown on a scale panel of each meter, thereby to indicate the absolute value, a resistance, the reactance or a VSWR value of the impedance to be measured. Accordingly, an antenna system can be adjusted considerably easily by bringing the indication of the meters close to zero.

Abstract: PURPOSE:To elongate the life of a photo-emitter and to improve the accuracy of the dimensions of a pattern to be exposed, by cooling a mask substrate, on which the photo-emitter is deposited. CONSTITUTION:A fluid is introduced through a fluid introducing terminal from the outside of a vacuum container 208 through a fluid introducing terminal 301. The fluid flows through a tube 302-1 and is outputted through a tube 302-2 to the outside of the vacuum container 208. Thus, a space constituted by a mask substrate 201, a glass plate 202 and a pushing plate 205 is filled with the fluid, and a photo-emitter, which is deposited on the mask substrate 201, is cooled. As the fluid used for the cooling, gas such as air and nitrogen and liquid such as pure water are suitable. The temperature of the mask substrate 201 itself or the vicinity of the substrate is measured by a temperature detector. By feeding back the result to a temperature controlling device, the temperature of the mask substrate 201 can be kept constant precisely.

IPC: H04M1/60
Filed: 1998-06-03
Abstract: PROBLEM TO BE SOLVED: To provide a hand-free telephone system capable of improving speech quality while preventing the occurrence of noise. SOLUTION: A signal transmission transformer 2 is connected between an analog signal input terminal 64 and a reception signal processing circuit 70, and a signal transmission transformer 3 is connected between an analog signal output terminal 65 and a coupling capacitor 69.

Title: Nonaqueous electrolyte secondary cell
Inventor: MATSUI TORU
IPC: H01M4/134
Filed: 1985-07-12
Abstract: PURPOSE:To make it possible to impregnate material inos easily to a negative electrode material to acquire a highly reliable nonaqueous electrolyte secondary cell, by forming uneven the surface of the negative electrode material where alkaline metallic ions are impregnated in charging and discharged in discharging condition. CONSTITUTION:When a negative electrode material sheet and an alkaline metal sheet are laminated and incorporated, the negative electrode material is made into an uneven surface with projections and recessions. Since the alkaline metal is soft, it sinks in the recessions while the projections of the negative electrode material are inserted into the alkaline metal. Therefore, the negative material sheet and the metallic sheet are closely attached in the uneven surface, and the electrolyte, when the laminated body is soaked therein, will not sink over the interface of the unevenness, while the electrical connection between the sheets is kept in a good condition until the alkaline ions are impregnated theroughly to the negative material sheet. Thus, the impregnation of the alkaline metallic ions to the negative electrode material is carried out stably and a highly reliable electrode is formed.
