Title: Bus control method in in-circuit emulator
Inventor: RYU KEN
IPC: G06F11/22
Filed: 1989-07-13
Abstract: PURPOSE:To improve processing efficiency by usually connecting CPU to the bus of debug space and connecting emulation CPU to the bus of user space through a re-try function when a target bus cycle is detected. CONSTITUTION:Usually, emulation CPU (CPU) 1 is connected to the bus 2 of debug space 3, and the target bus cycle which can be accessed to user space 4 is detected. When the cycle is detected, CPU 1 is connected to the bus 2 of user space 4 by using the re-try function as to CPU which repeats the same bus cycle by a request from an external part. Consequently, bus switching control is attained by using only the signal of a user level, and a special function is eliminated from adding to CPU 1. Thus, the processing efficiency of CPU 1 can be improved.

Filed: 1990-07-10
Abstract: PURPOSE:To prevent a leak while suppressing mechanical stress to a developer by forming a magnetic brush of a developer by magnetic field production members which have a 1st and a 2nd magnet, whose magnetic poles of the same polarity face each other, coaxially across a gap along the peripheral surface of a rotary shaft. CONSTITUTION:Cylindrical magnets 7A and 8B are the magnetic field generation members which are arranged along and opposite the peripheral surface of the rotary shaft 1 across the specific gap. Lines M of magnetic force from the magnet 7A deviate from the border part between both the magnets inward in a container and extend in the direction of the nonmagnetic rotary shaft 1. Magnetic particles are restrained along the lines M of magnetic force, and consequently the close magnetic brush B which deviates from the border part between both the magnets mainly inwardly in the container and extend in the direction of the nonmagnetic rotary shaft is formed of the developer 11 restrained by the cylindrical magnets at the gap parts between the cylindrical magnets and nonmagnetic rotary shaft. This brush B extends from the cylindrical magnets in the rotary shaft direction and uniformly in the peripheral direction. Further, the lines of magnetic force are directed to the nonmagnetic rotary shaft, so a magnetic seal is formed with a magnetic field concentrated locally on the gap between the cylindrical magnets.

Title: Production of fatty acid diethanolamide of lowered diethanolamine content
Inventor: MURAMATSU YOSHIKAZU
IPC: C07C231/24
Filed: 1991-06-27
Abstract: PURPOSE: To provide a method of producing fatty acid diethanolamide which is very low in diethanolamine content and shows high resistance to discoloration with a passage of time. CONSTITUTION: A fatty acid diethanolamide of formula I (R1 CO is a saturated or unsaturated fatty acid residue) containing unreacted diethanol-amine is combined with a fatty acid chloride of formula II (R2 CO has a C-number distribution the same as or more than 40% coinciding with R1 CO) to effect acylation to convert the diethanolamine as an impurity to a stable derivative whereby the product resisting to discoloration with a passage of time is obtained without adverse effect on its major properties or performances. If the fatty acid composition of the compound of formula II is on the lower fatty acid side than that of formula I, the thickening properties which is one of the major merits of the compound of formula I becomes poor, or if on the higher side, the cold stability are damaged.  The compound of formula I is a surfactant and a combination thereof with other surfactants gives the surfactant excellent foaming, penetrating and thickening powers.

Title: Power supply control circuit
Inventor: TATENO KENZOU
IPC: G05F1/56
Filed: 1982-10-19
Abstract: PURPOSE:To prevent a malfunction of the main body of a controller due to a sudden change of voltage, by rising up slowly to a desired level for the voltage to be applied to a follower device connected to a main controller, and preventing a rush current when the follower device requires a power supply. CONSTITUTION:An SW12 is closed when necessary through a power supply device 2 of a main body device 1 to supply the power to a follower device 4. A capacitor C is charged via a resistance R of a delay circuit 13, and the voltage of the capacitor C rises up in response to a time constant. Then a base current of a TR1 which is proportional to the rise of the voltage of the C flows, and a current proportional to said base current flows into the collector of the TR1 from the base of a TR2 via a resistance R3. Therefore, a current (i) which is supplied to a primary circuit 4a of the device 4 flows gradually from the emitter to the collector of the TR2. Then a steady state is obtained when the TR2 is saturated. This prevents a rush a current to the device 4 and then a sudden change of voltage of the power supply 2. Thus a mulfunction of the device 1 is prevented. This device is suited to a follower device of an elevator controller.
