Title: Driving circuit for parallel transistors
Inventor: TAKAMURA AKISUKE
IPC: H02M3/155
Filed: 1980-05-06
Abstract: PURPOSE:To approximately equalize the collector losses of two main transistors by detecting the difference of the storage times of the two main transistors and applying the time proportional to the difference to the transistor having short storage time during its driving time. CONSTITUTION:When a driving pulse VB is applied to an input terminal 14 and a reverse base driving transistor 22 is conducted, a pulse voltage VC having the storage time width of the corresponding transistor is produced across a resistor 25. When the difference of the pulse widths of the similar pulse voltage from other driving circuit and this voltage is detected by an NAND gate, an AND gate 29 selects the longer one. The NAND gate 36 produces a pulse VM for correcting the other transistor, this pulse VM and a controlling pulse VA are applied to the NAND gate 37, and are inputted from the outpt terminal 13 to other driving circuit. Thus, the base driving current of the other transistor increases its width in the amount corresponding to the corrected degree, thereby equalizing the energizing times of the collector currents of the two transistors.

Abstract: PURPOSE:To obtain a magnetic head which has the satisfactory recording capacity even to a recording medium of high coercive force and has excellent wear resistance, by forming a metallic magnetic layer of high saturated magnetic flux density to the head core main body of ferrite material so that the magnetic layer is set at the rear edge side of a head gap. CONSTITUTION:For a head for VTR and magnetic disk, a winding groove 5 is formed to a ferrite substrate 1. Glass 8 is filled into the groove 5, and then a nonmagnetic material like Al2O3, etc. is vapor-deposited to the groove 5 to obtain a gap layer 3. Then a metallic magnetic material like ''Sendust'', etc. is vapor-deposited to obtain a magnetic layer 4 of high saturated magnetic flux density. Then a track groove 2 is formed to obtain a head core block 10. The block 10 is cut after forming a protecting layer of SiO2, etc. on the layer 4. Then the glass 8 is excluded out of the groove 5, and circular polishing is applied to the tape contact surface as shown by alternate long and short dashes lines to finish the groove 5 down to the depth of the gap. Then a winding 6 is applied. Thus it is possible to obtain a head having high wear resistance and high recording/reproducing efficiency.

Title: Counting method for passing vehicle
Inventor: ODA GORO
IPC: E04H6/00
Filed: 1995-03-20
Abstract: PURPOSE: To surely count up the number of passing vehicles even when two or more vehicles having short inter-vehicle distances continuously pass by counting up passing vehicles only in an entry direction until the exit of a vehicle is detected at the time of detecting the entry of the vehicle from one entrance into a monitor area. CONSTITUTION: When a vehicle enters from the side of a detection area DA1, a count value '1' is outputted as the number of passing vehicles when the vehicle advances and exits from the side of a detection area DA2. When a vehicle enters from the detection area DA2 side, a count value '-1' is outputted as the number of passing vehicles. Thus the counting of passing vehicles is executed only in the entry direction based upon a transition pattern in the time sequence of detection states. Thereby even when two or more vehicles continuously pass the monitor area, the counting of the vehicles can be executed, and especially at traffic backup, passing vehicles can be surely counted up.
