Title: Flat brushless motor
Inventor: KAWAI TETSUO
IPC: H02K21/24
Filed: 1990-04-05
Abstract: PURPOSE:To realize a thinner motor by employing a quadruple pole where a set of magnets having opposing N poles and a set of magnets having opposing S poles, magnetized in a plane, are combined so that diamagnetic field is relaxed. CONSTITUTION:An NdFeB magnet having high remanent magnetization is machined into a piece of 2mm long, 1.4mm wide and 0.2mm thick and magnetized in the longitudinal direction (in the plane). N and S poles of such magnets are then opposed one another and stuck to an Al board having diameter of 11mm and thickness of 0.2mm thus forming a six pole rotor. Six coils having diameter of 2mm are then formed, through etching, on a glass epoxy substrate of 0.2mm thick plated with Cu in order to provide a stator which is then employed, together with the rotor, for formation of a motor. Clearance between the rotor and the stator is set at 0.1mm. Consequently, the thickness is reduced by a factor of two or more as compared with a conventional flat brushless motor.

Filed: 1981-06-15
Abstract: PURPOSE:To increase schedule speed, and to improve the comfortableness of travel by selecting the optimum braking force from the kinds of signals changing to the change of the lower rank of ATC signals and block length. CONSTITUTION:Speed input (a) taking in from a speed generator is wave-form shaped (1), and added to distance counters 2, 3.

The distance counter (A)  3 acquires the coordinates of the distance of a pattern required for controlling braking force. When the ATC signals (c) change to lower rank, a brake pattern  generator 7 reads the kinds of the ATC signals, the block length, the condition  of a gradient, etc., and generates a controlling pattern based on the content of  the distance counter 3. Accordingly, schedule speed can be increased, and the comfortableness of travel can also be improved.

Title: Semiconductor logical integrated circuit

IPC: H03K19/003
Filed: 1984-05-09
Abstract: PURPOSE:To always maintain the reference voltage at an intermediate potential of a logical amplitude despite of the variance of the manufacturing process or the power supply voltage, by using a diode to clamp the area between a power supply and an output terminal of an SCFL (source coupling type FET logic) circuit. CONSTITUTION:Diode groups 100 and 101 and 102 and 103 of series connection of 2n pieces are connected in parallel to load elements 10 and 11 of the 1st SCFL circuit and load elements 12 and 13 of the 2nd SCFL circuit respectively. Thus the area between a power supply terminal 1 and 2 and the outputs of SCFL circuits is clamped. The reference voltage VREF is produced by a group 200 of (n) pieces of diodes connected in series and a current source 32. Then VOL=VDD-2nphiD and VOH=VDD are satisfied between low and high levels VOL and VOH of a logical output signal voltage of the SCFL circuit, where the power supply voltages of terminals 1 and 2 are set at VDD with the barrier voltage of the diode is set at phiD respectively. Then VREF=(VOH+VOL)/2 is satisfied since VREF=VDD-nphiD is satisfied. Thus the reference voltage is kept to the intermediate potential of a logical amplitude regardless of variances of VDD and phiD.

Title: Detector of pulse duration
Inventor: NISHI HARUHIKO
IPC: G01R29/027
Filed: 1979-07-19
Abstract: PURPOSE:To avoid the continuous delivery of the output by cutting off the output in case an extraordinarily long input pulse is applied and by providing the comparator and the switching element. CONSTITUTION:With application of the negative pulse to input terminal 1, capacitor 4 is charged. And the charging voltage is compared with the reference voltage by comparator 6. If the charging voltage is higher than the reference voltage, comparator 6 generates the output to detect the length of the pulse duration. In this case, if an extraordinarily long input pulse is applied, the output is delivered continuously. In this connection, the voltage of capacitor 4 is compared with the reference voltage by comparator 9 having prescribed reference voltage source 8. And when the voltage of capacitor 4 is higher than the reference voltage, switching element 10 is actuated to cut off the output of comparator 6. In such way, the continuous delivery of the output can be avoided.

Filed: 1990-04-09
Abstract: PURPOSE:To suppress slag foaming which allows easy automation by blowing water or water contg. fine particles at a specific flow velocity to the slag foaming in a vessel. CONSTITUTION:The high-pressure water flow 4 of >=20m/sec flow velocity is injected from a lance 3 through the mouth of the receiving vessel 1 to the surface of the slag 5 at the point where a molten iron 6 flowing down from a tilting trough 2 is received. The slag layer 5 is cut from the molten iron 6 by the spraying of the high-pressure water, by which gaseous CO is removed and the foaming is suppressed. The water cutting the slag layer 5 arrives at the surface of the molten iron 6 and generates a small steam explosion by reacting with the high-temp. molten iron 6, thereby breaking the slag layer 5. A higher effect is obtd. if the water contg. the fine particles of ceramics, etc., is used for the slag 5 having a high viscosity or the slag 5 cooled and solidified on the surface.
