Title: Information processor
Inventor: KANEKO EIJI
IPC: G06F1/32
Filed: 1999-06-24
Abstract: PROBLEM TO BE SOLVED: To reduce the power consumption and to suppress the discharging current from a battery, and to prolong the operable time by controlling a clock supplied to a CPU by always monitoring the output voltage of the battery and changing the control method of the CPU according to information from a voltage monitor circuit. SOLUTION: The output of the battery 100 is inputted to a DC/DC converter 102 and converted into a voltage that a system requires. Settings are made in a nonvolatile memory 108 so that when the output voltage of the battery 100 reaches a set voltage, a voltage detecting circuit 101 generates an output. When the voltage detecting circuit 101 detects the set voltage and its detection signal 114 becomes logic 0, a CPU control circuit 107 issues a system management interrupt(SMI) 105 to the CPU 104. The CPU 104 having known a drop of the output voltage of the battery 100 makes active a clock frequency switching acknowledgement signal 115 connected to a general output port to switch a clock frequency.

Title: Switch having confirming function of atm status panel
Inventor: OTA HIDEO
IPC: H04L12/70
Filed: 1998-06-25
Abstract: PROBLEM TO BE SOLVED: To confirm the extent of an ATM connection procedure and also to shorten the maintenance time by displaying the said procedure on the panel of an ATM switch itself. SOLUTION: A switch having a confirming function of an ATM status panel consists of an ATM interface 1, a CPU 2, an LED light emitting device 3 and an LED. In an ATM connection mode, the CPU 2 produces a signal to the device 3 for every successful procedure. Receiving this signal, the device 3 turns on the LED attached to the front panel of an ATM switch. Thus, it's checked whether the ATM connection is successful after its start. If the ATM connection is not successful, the procedure is returned to the start of the ATM connection. If the ATM connection is successful, this success is reported to the CPU 2 and displayed by the LED.

IPC: G11B15/67
Filed: 1987-07-20
Abstract: PURPOSE:To prevent a magnetic tape from being folded due to winding slack by providing a tape tension making constant means and a vibrating windup means driving the magnetic tape in a cartridge in opposite direction so as to prevent the winding slack of the magnetic tape. CONSTITUTION:The tape tension constant windup means controls a machine motor 32 so as to keep the supply speed of the magnetic tape 10 from the cartridge 20 and the winding speed of a machine reel 33 constant thereby winding the tape 10 on the reel 33.

IPC: H02K1/27
Filed: 1995-06-21
Abstract: PURPOSE: To obtain a stepping motor by which an attractive force and a repulsive force are generated in all of a plurality of permanent magnets and by which a large torque is generated by a method wherein a correlation between magnetic fluxes generated in the plurality of permanent magnets installed on the outer circumference or the inner circumference of a first rotor part and a second rotor part and a magnetic flux generated, in a loop shape, on a face parallel to the axial direction of a stator is displaced in the rotating direction. CONSTITUTION: In a stepping motor 10, a first rotor part 20A and a second rotor part 20B as well as a third rotor part 20C and a fourth rotor part 20D are shifted by a 1/4 pitch portion. Thereby, in all permanent magnets 44 arranged on the outer circumference of a rotor 20, an attractive force or a repulsive force is generated. When the polarity of every permanent magnet 44 and that of every pole tooth faced with it are equal, the pole tooth generates an attractive force with reference to cores 20a to 20d at the rotor 20, a propulsive force is generated when the attractive force is added, and a torque becomes large. Consequently, the stepping motor which is small and which can generate a high torque can be obtained.

Filed: 1988-07-19
Abstract: PURPOSE:To eliminate the variation of a characteristic caused by an oriented state and to obtain the high speed responsiveness by providing a means for setting forcibly a liquid crystal molecular orientation of a liquid crystal part which can be driven to one of a stable or metastable oriented state at the time of switching off. CONSTITUTION:At the time of switching off the element, a liquid crystal molecular orientation of a liquid crystal part which can be driven is set forcibly to one of at least two stable or metastable oriented states. That is, the switch is set to three stages of ON-READY-OFF, and when it is in a READY state, a driving circuit part is operated so that the liquid crystal molecule always takes a prescribed orientation. When it is in an OFF state, the driving circuit is set to a non-operating state after an electric field has come not to be applied between the upper and the lower electrodes. In such a way, the characteristic variation caused by an oriented state of a non-driving period is eliminated, and the high speed responsiveness is obtained.
