Title: Ignition unit for internal combustion engine
Inventor: YAMAMOTO NOBORU
IPC: F02P15/12
Filed: 1980-12-08
Abstract: PURPOSE: To make it possible to supply a constant ignition current, even when the line voltage is varied, by providing a correction circuit to a constant current control circuit for a primary current of an ignition coil.  
     CONSTITUTION: When a line voltage is high, a transistor 15 is turned off. Therefore, a reference voltage (L point voltage) is turned into a voltage of Zener diode devided by resistors 37 and 38. When the line voltage drops, the potential at K point is lowered. As the emitter potential of the transistor 15 rises, however, the potential at L poit can be maintained practically constant. With this construction, the electric current of the ignition coil can be maintained constant, even when the line voltage varies.

Abstract: PURPOSE:To lessen evaporation of Pb and suppress pyrolysis of the perovskite phase of a dielectric material by specifying the mol ratio A/B in the range 0.80-1.00, where A is Pb element and B is A, Mg, Nb, Ti, Mn elements. CONSTITUTION:The mol ratio A/B is set in the range 0.80-1.00, where A is Pb and B is A, Mg, Nb, Ti, Mn. The composition of each element should be 65.0-70.0wt.% in the equivalent of PbO 3.0-6.0wt.% in the equipment of MgO, and 22.0-29.0wt.% in the equivalent of NbO5/2. The compound further includes 0.5-2.5wt.% Ti in the equivalent of TiO2, 0-1.0wt.% Mn in the equivalent of MnO, and 0.001-1.0wt.% Cu in the equivalent of CuO. According to this constitution, the wettability and tight attachment of the internal electrode with the matrix material are enhanced, and interrugtion of the internal electrode can be eliminated if Cu in the dielectric material is dispersed at the time of baking to lead to further enhancement of tight attachment. Evaporation of Pb is lesser if baking is made with a high oxygen concentration, and pyrolysis of the perovskite phase in the dielectric material can be suppressed.

Title: Magnetic recording and reproducing device
Inventor: KAKIMOTO TEIJI
IPC: G11B15/675
Filed: 1990-06-30
Abstract: PURPOSE:To suppress back tension low against a capstan in the case of the traveling of a tape and to secure stable take-up tension even if drawing tension is set to be slightly high by imparting the brake force of prescribed torque to a capstan motor at the time of recording/reproducing after tape loading is completed. CONSTITUTION:Since brake force by a brake mechanism is imparted to the capstan motor 18 by interlocking it with the operation of tape loading mechanisms 5-8 to draw the tape from the tape cassette 1 in a cassette loading position, the brake force of prescribed torque is imparted to the capstan motor 18 at the time of recording and reproducing. Since back torque is set slightly higher for correspondence to the increase of the low torque of the cassette 1, brake force is imparted to the capstan motor 18. Thus, a load to the capstan motor 18 can be prevented from becoming negative and stable servo can be executed.
