Title: Drive controller of semiconductor switch element
Inventor: FUKAZAWA KATSUMI
IPC: H03K17/687
Filed: 1983-05-12
Abstract: PURPOSE:To ensure the stable drive of a semiconductor switch element without increasing the power loss of a resistance by short-circuiting a part of a series resistance when the charging voltage is less than a prescribed level. CONSTITUTION:When the voltage of a DC power supply 1 has a drop, the voltage of a capacitor C1 is also reduced less than the Zener voltage of a Zener diode DZIA. As a result, the non-inverted input voltage of a comparator 6 is reduced less than the inverted input. Therefore the output of the comparator 6 is set at level ''O'', and a current flows to a photodiode PD3. Thus a phototransistor PT3 is turned on. Then only an R5 has the charging resistance of the C1, and therefore the charging current increases. Thus the voltage of the C1 can be increased. In other words, a switch circuit using the PT3 is acutuated in response to the voltage of the C1 to switch the charging resistance. Thus a satisfactory charging resistance is always obtained.

Title: Rotary magnetic head assembly
Inventor: AOKI TATSUJI
IPC: G11B5/41
Filed: 1988-03-31
Abstract: PURPOSE:To prevent wear particle which has occurred by means of the contact of a magnetic head and a tape from being adhered to the other magnetic head by providing a cleaning pseudo magnetic head between the magnetic heads on a rotary magnetic assembly. CONSTITUTION:The first pseudo head 6 is installed between the first magnetic head 2 and the second magnetic head 3. Since the head 2 is slidably brought into contact with the tape 8 at a high relative speed, wear particle 10 occurs. Wear particle 10 floats in an inverse direction with respect to a head proceeding direction in a space layer 9, and it adheres to the operation surface of the head 6. Consequently, wear particle 10 does not reach the slidable surface of the head 3. Since the wear particle 10 does not adhered to the head 3, the output of the magnetic head can stably be obtained.

Title: Evaporated fuel controller for internal combustion engine
Inventor: INADA MASANORI
IPC: F02D41/22
Filed: 1991-04-15
Abstract: PURPOSE:To correctly detect the trouble of an evaporated fuel controller by judging the normalcy and anomaly from the difference in air-fuel ratio feedback correction value between before and after the opening of a purge control valve in the cases where the concentration of the upstream side evaporated fuel which is detected when the purge control valve is closed is a prescribed value or over. CONSTITUTION:The air-fuel ratio corresponding to the output of an exhaust sensor 7 for detecting the oxygen concentration in exhaust is controlled so as to be equal to a prescribed value. When the output of a fuel concentration sensor 19 for detecting the concentration of the evaporated fuel on the upstream sides by a purge control valve 18, in the closed state of the purge control valve 18 is over a prescribed value, a control unit 2 judges that the evaporated fuel control is normal, when the difference of the correction value of the air-fuel ratio feedback control between before and after the opening of the purge control valve 18 is over a prescribed value. Further, it is judged to be abnormal when the difference is less than a prescribed value. Since the concentration of the evaporated fuel in the case when a trouble is detected is large, the difference due to the existence of trouble is made distinct, and the trouble detection can be carried out correctly with high reliability.
