Title: Contact material
Inventor: TSUJI MASAYUKI
IPC: H01H1/023
Filed: 1985-04-24
Abstract: PURPOSE:To obtain a contact material having much superior melt sticking resistance and contg. a very small amount of a harmful element by dispersing prescribed percentages of Li and Cd in Ag in the form of metallic oxides by an internal oxidation method. CONSTITUTION:Li oxide and Cd oxide are formed in Ag by an internal oxidation method and dispersed in the Ag to obtain a contact material. At this time, it is necessary to regulate the Li oxide content to 0.1-3 wt% (expressed in terms of Li) and the Cd oxide content to 0.01-2 wt% (expressed in terms of Cd). It is preferable that at least one kind of transition metal selected among Fe, Ni and Co is further added to the Ag and oxidized by the internal oxidation method so as to make the grains of the matrix of the contact material fine.

Title: Base drive circuit for transistor
Inventor: ISHIBASHI HIDEAKI
IPC: H02M1/08
Filed: 1990-04-04
Abstract: PURPOSE:To reduce base driving power by reducing the forward bias base current for a main transistor to approximately zero if the collector.emitter voltage of the main transistor has negative polarity when a diode is conducting forwardly. CONSTITUTION:A base drive circuit comprises a comparator CP, diodes D1, D2, resistors R1, R2 and a polarity judging unit for judging the polarity of the collector.emitter voltage of a main transistor 2 containing the diodes D1, D2. If the diodes D1, D2 are conducting forward according to the control mode of the entire controller including the transistor 2 and the collector.emitter voltage of the main transistor 2 has negative polarity, when a forward bias base current is fed to the main transistor 2 for the purpose of conduction, the forward bias base current to the main transistor 2 is immediately reduced to approximately zero. Consequently, the base driving power of the main transistor 2 can be reduced without causing increase of loss.

Title: Measuring apparatus for curvature and torsion
Inventor: URANO MASASHI
IPC: G01B7/30
Filed: 1979-07-14
Abstract: PURPOSE: To make it possible to measure the curvature and torsion of building materials, etc., by vertically moving a resistance bar in accordance with the unevenness of a material to be measured by sliding the resistance bar on the top surface of the measured material, and then by reading its extent of movement in terms of variation in resistance value.  
     CONSTITUTION: Material 1 to be measured is mounted on horizontal mount table 11 and support legs 9 and 10 of a curvature and torsion measuring apparatus are moved along the top surface of mount table 11. At this time, resistance bar 2 moves vertically in accordance with the curvature and torsion of material 1 to be measured and the distance between sliding contact segment 15 and fixed contact 20 at the tip of resistance bar 2 varies. Since the resistance value between sliding contact segment 15 of resistance bar 2 and fixed contact 20 varies in proportion to their distance, the resistance value variation is read by an electric resistance measuring apparatus connected between lead wires 18 and 19, so that the curvature and torsion states of material 1 to be measured can be found to the contrary.

Abstract: PURPOSE:To make an amplifier efficient by incorporating an output difference detector for the amplifier in each output stage in the high-output amplifier of a microwave band and improving the output synthesis efficiency on a basis of its detection level at an adjustment time. CONSTITUTION:The output of an amplifier 2 in the first stage is divided into two by a hybrid 3 for power distribution and is supplied to amplifiers 5 and 6 in output stages. When outputs of amplifiers 5 and 6 in output stages are inputted to a power synthesizing hybrid 7 by adjusting degrees of amplifications and phase characteristics of both amplifiers with a bias voltage or the like, they have phases opposite to each other in the terminal of an attenuator 8' and have the same phase in the terminal of an output line 9.
