Title: Speed control method for stacker crane
Inventor: AOYANAGI MITSUO
IPC: B65G1/04
Filed: 1995-05-31
Abstract: PURPOSE: To suppress follow-up lag due to inertia and improve operationability by timer-setting traveling time from a current position to the first decelerating process start position, conducting timer-measuring at the same time as starting with the current position, and conducting deceleration and stopping when a timer measurement has reached a timer preset value. CONSTITUTION: When the current position of a stacker crane 15 is sufficiently far from a targeted position (address Sn) O like addresses S1-Sn-5, traveling time from the current position to the first decelerating point P1 is computed and determined from a distance from the current position to a targeted position O, acceleration α, deceleration -α and low speed Lv. The obtained traveling time is set at a timer and timer measurement is conducted upon starting traveling. When the value measured by the time has reached a timer preset value, or the first decelerating point P1, the stacker crane is decelerated at a deceleration -α, and when it has reached low speed Lv, the crane is traveled to the second decelerating point PO at a low speed Lv.  When it has reached the second decelerating point PO, the crane is decelerated at the deceleration -α and stopped at the targeted position O.

Title: Data transmission control unit in multi-cpu system
Inventor: MARUTA SHUJI
IPC: G06F15/16
Filed: 1987-06-26
Abstract: PURPOSE:To attain communication by providing a bypass circuit in disconnecting an optional slave CPU via a loop line of a transmission enable signal so as to bypass the enable line to a low-stage CPU. CONSTITUTION:An output of a transmission enable signal from a host CPU 1 to a slave CPU 12-1 is managed by the CPU 1 and the data transmission right among the CPUs 2-1-2-3 is circulated sequentially. When a slave CPU provided with the transmission right aborts the transmission right, a corresponding 3-stage gate (6-1-6-3) is opened by pull-down resistors 7-1-7-3 and a bypass circuit transferring the transmission right to a slave CPU of the next stage is provided. Thus, even when an optional CPU of a middle stage is disconnected through the loop line of the transmission enable signal, the enable line is bypass without hindrance and connected to the slave CPU of the lower stage thereby attaining the communication.

Abstract: PROBLEM TO BE SOLVED: To reduce the size of a motor by disposing magnetic sensors to generate sine wave voltages having 120 deg. phase shift, converting the generated three- phase sine wave voltages into a PWM signal and inputting the PWM signal to a three-phase inverter. SOLUTION: A magnet 3 is fixed to the rotary shaft 2 of a three-phase brushless motor 1, and the strength of a sine wave magnetic field generated as the rotary shaft 2 rotates is converted into a similar voltage, by means of a plurality of magnetic sensors 4 secured to the stator of the motor. The magnetic sensors 4 are disposed to generate sine wave voltages having 120 deg. phase shift, and the sine wave voltages are amplified by an amplifier 5 to produce three-phase sine wave voltage signals 6. The three-phase sine wave voltage signals 6 are inputted to a PWM conversion circuit 7, which delivers a PWM signal 8 to a three-phase inverter 9, thus producing power for driving the three- phase brushless motor. Since an intricate drive circuit is eliminated, the motor can be reduced in size.

Title: Plain bearing
Inventor: IMAI KIYOSHI
IPC: C25D7/10
Filed: 1985-07-18
Abstract: PURPOSE:To make sharp improvements in anticorrosiveness, abrasion resistance and fatigue strength, by constituting a surface overlay stratum with a soft component in the upper layer and a hard component in the lower layer, respectively. CONSTITUTION:A lower overlay stratum 4 increasing a mount of tin and copper content is formed in a back metal 1 so as to improve abrasion resistance via an aluminum alloyed layer 2. In addition, an upper overlay stratum 5 of 5-15mu being relatively soft and excellent in fittability and embeddability is formed on the back metal as well. Here, a drop in fatiguelessness due to an increase in the tin contact is covered with a way of thinning thickness of the lower overlay stratum 4, while a drop in the fatiguelesssness due to an increase in the copper content is kept back in a way of reducing the thickness of the lower overlay stratum 4. Therefore, these of anticorrosionness, abrasion resistance and fatigue strength are all sharply improvable.
