Title: Speed change control device for automatic transmission
Inventor: TABATA ATSUSHI
IPC: F16H61/16
Filed: 1992-05-20
Abstract: PURPOSE:To prevent an inadequate speed change by providing a speed change regulation means for regulating speed changes which are based on speed change instruction signals from a manual speed change instruction mechanism when manual speed change mode is entered. CONSTITUTION:A speed change normally occurs in response to a signal issued when manual speed change mode is selected by a shift mechanism 1 as well as a speed change instruction signal issued when a manual speed change instruction mechanism 2 is operated. When automatic speed change mode is switched to manual speed change mode, a speed change regulation means 3 regulates speed changes which are based on speed change instruction signals from the manual speed change instruction mechanism 2. Therefore, if for example, the shift mechanism 1 is used to select manual speed change mode when a speed change has been requested by the manual speed change instruction mechanism 2, a speed change is not performed until a specified length of time has elapsed since the selection of manual speed change mode, thereby preventing an inadequate speed change.

Title: Degaussing method for magnetic head
Inventor: AIDA AKIRA
IPC: G11B5/465
Filed: 1987-06-22
Abstract: PURPOSE:To degauss a magnetic head to prevent the degradation of S/N due to head magnetization by gradually attenuating a recording current at the time of switching plural magnetic heads to one another. CONSTITUTION:In a device where plural magnetic heads are switched to one another to record and reproduced a signal, the recording current is gradually attenuated after contacting between the magnetic head and a tape is terminated.

Title: Switching power supply
Inventor: HIRONO ATSUSHI
IPC: H02M3/28
Filed: 1990-06-11
Abstract: PURPOSE:To inhibit the variation of an overcurrent protection staring point due to the change of input voltage by connecting a resistor forming a time constant circuit in parallel with a series circuit of another resistor and a Zener diode to form another time constant circuit. CONSTITUTION:A resistor 12 forming a time constant circuit is connected in parallel with a series circuit of a resistor 22 and a Zener diode 24 reverse- biassed by the voltage Vb of the bias winding 2c of a transformer 2, so that another time constant circuit 12a is formed. When input voltage Vi is increased, the voltage Vb of the bias winding 2c of the transformer 2 rises and voltage Vr applied to a synthetic circuit also rises and the combined resistance value is reduced, thus lowering the time constant of the time constant circuit 10a. Consequently, a transistor 20 is turned ON earlier, and a MOSFET 6 is turned OFF earlier and a protective mode is acquired. Accordingly, the variation of an overcurrent protection starting point due to the increase of oscillation frequency can be inhibited.

Title: Control method for constant feed ware
Inventor: NAKAMOTO AKIRA
IPC: G05D7/00
Filed: 1982-09-02
Abstract: PURPOSE:To improve accuracy of discharging a specified quantity of flow by a method wherein a control signal of a discharging device is controlled in such a way as discharging capability is set to a certain constant in response to the weight of the discharged item in a weighing hopper. CONSTITUTION:For example, when the first screw feeder is to be controlled, CPU11 at first checks if the operation is in its suplying period, and when the operation is in the discharging period, the updated weight is read from A/D converter 10 and a discharging quantity of feeder per unit time is calculated in reference to a difference between the updated weight and previously read the former weight and then the value is compared with the desired flow rate F. A control signal for a motor 6 is varied through a motor control circuit 5 in such a way as the actual discharging quantity approaches the desired flow rate F and then the newest read weight is checked if it coincides with the predetermined value and the lower limit setting value WL. When the coincidence is detected, the control signal for the motor 6 is stored in the addresses A, B and C in the memory 12. In this way, a control signal for the motor 16 is changed over in response to the weight and a variation in flow rate in the supplying period is improved.
