Title: Dc voltage converting circuit
Inventor: SHIGEMATSU NANA
IPC: G05F1/56
Filed: 1988-03-28
Abstract: PURPOSE:To easily extract current and voltage outputs by changing the constitution of a negative feedback circuit externally connected to an IC in a DC-DC converter for an electronic tuner. CONSTITUTION:The negative feedback circuit 25 is connected between externally connecting pins 18e, 18g for the IC 18 so as to short between both the pins 18e, 18g and ground the pin 18g through a resistor R4 and an externally connecting pin 18f is connected to a current output terminal 26. An output from a constant voltage source 19 is applied to a reference voltage generating circuit 21 and npn transistors (TRs) Q1, Q2 through a boosting circuit 20 in the IC 18. The TR Q2 has N times the emitter area of the TR Q1. A reference voltage output is inputted to a DC amplifier circuit 23 through an externally connected resistor voltage dividing circuit and the potential of the pin 18e is negatively fed back to the circuit 23. When the outputs of the pins 18e, 18f are connected to each other and negatively fed back to the circuit 23 through a circuit consisting of the externally connected resistor voltage dividing circuit, a voltage output can be obtained from the pin 18e.

Title: Controller for engine
Inventor: NAKAMURA KOICHI
IPC: F02P3/045
Filed: 1991-03-13
Abstract: PURPOSE:To generate an ignitor control signal suitable for the revolution of an engine by using the simple hardware constitution. CONSTITUTION:An ignitor control signal IGT for controlling the electric conduction of an ignition coil on the basis of the ignitor control signal IGT synchronized with the revolution of a crank-shaft is generated. A counter counts up the prescribed clock in the front half cycle T1 and counts down the prescribed clock in the latter half cycle T2. The signal IGT is started up at the time point t4 when the count value C in count-down reaches a threshold value alpha0, and starts down the signal IGT at the completion time point t3 of the cycle T. The clock signal used in count-down is varied according to the engine revolution speed. In the lower engine revolution speed, counting is performed along a graph X by using the clock having the lower cycle, and the pulse having a width (t) is obtained. In the high engine revolution speed, counting is performed along a graph Z by using the clock having the higher cycle, and the ratio t/T is increased.

Title: Taper forming method
Inventor: YOKOYAMA KATSUYOSHI
IPC: B21D41/04
Filed: 1979-06-14
Abstract: PURPOSE: To perform taper forming without any vibration, noise, etc. by compression-molding the work by forming rolls continuously.  
     CONSTITUTION: The revolutions of a motor are transmitted to a driving shaft 7→driving gear 8→driven gears 11, 11→supporting shafts 12, 12→universal joints 13, 13→revolving shafts 5, 5, causing three pieces one set of forming rolls 1, 1 to make respectively eccentric revolutions about the eccentric centers 0, 0. The revolutions comprising expanding the opposing spacings of the forming rolls then decreasing the same to return the rolls to the original opposing positions are repeated. The work M is pushed from backward by pressing force P. When the opposing spacings of the forming rolls 1, 1 expand, the front side of the work advances from the large- diameter portions 1a, 1a toward the small-diameter portions 1b, 1b until it contacts the tapered faces of the forming rolls. As the opposing spacings decrease, the end receives compression and becomes smaller and this process is repeated. Hence, the work M is formed to a taper shape subsequently.
