Title: Signal amplification utilizing voltage inclination of maser spectrum
Inventor: KAMIMURA MUTSUJI
IPC: H01S1/02
Filed: 1981-12-09
Abstract: PURPOSE:To sensitively amplify an NMR signal (Nuclear Nagnetic Resonance absorption signal), and a superconductive current flowing through a SQUID (Superconductive Quantum Interferometer), by utilizing a steep inclination of a solid-state master spectrum. CONSTITUTION:In a cavity 2, a coil 4 is firmly fixed by being wound around a master sample (ruby) 3 in parallel with the field. Then, an external field is fixed at the position 11 of the solid-state master spectrum 10, and the NMR signal 14 current is passed to the coil 4 resulting in the signal oscillation of the field. The voltage fixed at the position 11 of the solid-state master spectrum 10 goes out as the output NMR signal 15 voltage by this field oscillation. Next, when the superconductive current 16 flowing through the SQUID is passed to the coil 4 as the signal, the superconductive current 17 flowing through the SQUID goes out. By repeating this amplification in several time feedbacks until the maser voltage inclination 12 is saturated, the signal (NMR signal, and the superconductive current flowing through a SQUID) can be sensitively taken out at a very large gain.

Abstract: PURPOSE:To give initial deviation of a belt to a belt drive device capable of automatically detecting and correcting the deviation with simple constitution. CONSTITUTION:A transfer belt 4 capable of travelling is trained over three first-third rollers 1-3. A deviation detecting member 11 is disposed on the shaft end of the third roller 3. The rotational torque of the deviation detecting member 11 generated by the contact of the deviated transfer belt 4 with the deviation detecting member 11 is utilized to generate the reverse deviation component in the transfer belt 4 for cancelling the initial deviation. The tubular body 2b of the second roller 2 as an initial deviation giving means is divided into left and right tubular body sections 2c, 2d. The coefficient of friction between the left side tubular body section 2c at the disposed deviation detecting member 11 side and the transfer belt 4 is made smaller than that at the right side tubular body section 2d so that the deviation toward the deviation detecting member 4 side is carried out in the travelling transfer belt 4.

Title: Timing generating circuit
Inventor: MATOBA TAKASHI
IPC: H04L7/02
Filed: 1985-09-10
Abstract: PURPOSE:To obtain an output by a clock of a half frequency by providing a frequency division circuit operated by clocks of opposite phase, operating flags inhibiting the operating of the one when the other starts the operation and a OR circuit connecting the two outputs. CONSTITUTION:When an input signal IN descends to '0' with a clock phi2 at logical '1', an output of the OR circuit 12 goes to '0' and the output of a NOR circuit 13 goes to '1'. When the clock phi2 descends to '0' with a D input of a DFF 11 at logical '1', the output OA of the DFF 11 is inverted to '1' and an output FA of the D latch 21 goes to '1'. Since the output of a OR circuit 32 goes to '1' and an output of a NOR circuit 33 goes to '0' with the output FA at logical '1', the output OB of the DFF 31 goes to '0' regardless of a clock phi2, the output FB of the D latch 41 remains '0' and the operation of the DFF 31 and the D latch 41 is inhibited. When the lock PHI2 descends from '1' to '0' again, since the D input of the DFF 11 is '0', the output OA goes to '0'. The DFF 11 repeats frequency division synchronously with the trailing of the clock phi2 and a signal OUT outputted from a OR circuit 50 is obtained at a 1/2 frequency of the clock phi2.

Title: Non-aqueous electrolytic battery
Inventor: YOSHIHISA HIROYOSHI
IPC: H01M4/13
Filed: 1997-07-28
Abstract: PROBLEM TO BE SOLVED: To prevent an unexpected rise of battery internal temperature, prevent electrode and electrolyte from reacting to each other, and improve safety of a battery, by building-in the metal halide having a melting point within a specific range. SOLUTION: When a short circuit occurs in a battery and the temperature rises by Joule's heat, before it rises to a temperature at which chemical reaction between an electrode and an electrolyte occurs, generated heat must be removed speedily to prevent the temperature from rising. Therefore, materials which have a melting point lower than the temperature at which the reaction occurs are built-in. Metal halide with 100-300 deg.C melting point is preferable. Especially, halide of Mo, Si, Sn, Bi, and Zn is general and preferable because it is inexpensive and nontoxic. Because the metal halide melts, covers an active material surface, and cuts off the contact with the electrolyte, it is preferably located in the electrode or on the interface of the electrode and the separator.

Filed: 1996-07-31
Abstract: PROBLEM TO BE SOLVED: To reduce a time required for automatic channel selection by deciding the pressure/absence of a station, except in the vicinity of a frequency which has already been set. SOLUTION: In the case of automatic channel selection, at first a demodulation circuit 16 is set to a SECAM system, and a presence/absence of station decision circuit 20 decides whether or not a reception frequency includes a broadcast signal, based on a synchronizing signal included in a composite video signal demodulated by the circuit 16. When the presence of station is decided, a microcomputer 22 sets the frequency. When the automatic channel selection for the SECAM system is finished, the demodulation circuit 16 is set to the PAL system, and frequencies including broadcast stations are set similarly to the foregoing. However, in the case of the automatic channel selection for the PAL system, presence/absence of station is decided, except in the vicinity of the frequencies already set.
