Title: Electric rolling stock controlling device
Inventor: KATOU TAKETOSHI
IPC: H02P3/10
Filed: 1979-03-19
Abstract: PURPOSE: To prevent a current limiting circuit from operating at plugging to weaken a stopping force by selecting a current limiting operative minimum conductivity greater than a maximum braking torque generating conductivity necessary for plugging.  
     CONSTITUTION: Either of ahead/astern changeover switches 2 or 3 is closed to normally-close contact side, and conductivity of a chopper 6 is controlled by an accelerator controlling circuit 7 to drive a motor 1b. It is arranged such that from changing the switch 2 or 3 to keep a vehicle reversely braked, a plugging circuit 10 operates on the controlling circuit 7 to decrease the chopper conductivity, and a smooth braking torque is thus obtainable. Where in this case the plugging current becomes greater than a motor current value suppressed by a current limiting circuit 12, the conductivity will not come below a value determined by resistance values of resistors 12e, 12f, thereby keeping a stopping force from being weakened.

Title: Controller for heater
Inventor: ISHIDA KAZUHARU
IPC: F23N5/14
Filed: 1999-02-10
Abstract: PROBLEM TO BE SOLVED: To approach the upper limit of heat generation to a selected level when the area of a room is varied by advancing the upper limit by one rank if the room temperature does not reach a set level and correcting the upper limit downward if the upper limit is higher, in rank, than a selected value. SOLUTION: If a set room temperature can not be sustained using an upper limit set by a current upper limit altering means 7 and the room temperature is lower than the set level, the means 7 advances the upper limit being set by an upper limit setting means 8 by one rank. Furthermore an upper limit being set by the means 8 is altered while setting larger one of a lowest rank upper limit of heat generation selectable through an upper limit selecting means 6 including current level of heat generation or an upper limit of heat generation selectable through the upper limit selecting means 6 as an upper limit. The set room temperature is reached by altering the upper limit temporarily and then the upper limit is corrected under a state where sufficient control can be performed with low heat generation.

Title: Laser exposing method for picture scanning and recording device
Inventor: TASAKA KAZUTAKA
IPC: B41J2/44
Filed: 1989-02-10
Abstract: PURPOSE:To attain exposure and recording with an optimum exposing method in correspondence to picture quality, which is requested to a pattern to be drawn, by arbitrarily selecting the exposing method to execute the exposure and recording with overlapping one part of a multibeam and the exposing method to execute the exposure and recording without overlapping the multibeam. CONSTITUTION:To a cross point data processing circuit 21 and a memory controller 22, a mode designating signal to designate a recording mode is given as a control signal from a picture data preparing part 10. As the recording mode, there are a mode (overlap presence mode) to execute the exposure and recording with overlapping one part of an adjacent beam spot and a mode (overlap absence mode) to execute the exposure and recording with making the respective beam spots adjacent. These exposing methods are switched and selected in correspondence to the picture quality, which is requested to the picture to be recorded, and the exposure and recording is executed. Thus, when the high picture quality is desired to be obtained, the overlap presence mode can be selected and on the other hand, a drawing speed is desired to be preferential rather than the picture quality, the overlap absence mode can be selected.

Title: Bus arbiter
Inventor: GOTO NORIKAZU
IPC: G06F13/26
Filed: 1988-02-17
Abstract: PURPOSE:To avoid the deterioration in bus availability by giving a permission for data bus application to data bus application requests having higher frequencies with preference among those requests of plural devices. CONSTITUTION:A device 1 having a data bus application request drives a data bus application request line 2. A bus arbiter 5 monitors the line 2 and performs comparison among those data bus application request frequencies of plural devices 1. Then the arbiter 5 gives the permission for use of the data bus to those devices having higher request frequencies. Thus it is possible to avoid the deterioration in bus availability without complicating the operation of the bus arbiter 5 due to the dependence on the priority orders only of the device 1 nor performing the polling action in a fixed cycle. As a result, the availability of the data bus is improved.

Filed: 1998-02-16
Abstract: PROBLEM TO BE SOLVED: To provide an optical transmission system, an end terminal and an optical repeater with which the improvement in the reliability of an entire system can be attained by enabling optimum control to the transmission level of the optical signal of each wavelength among wavelength multiplexing optical signals. SOLUTION: A wavelength multiplexer 91, to which a lot of optical signals having different wavelengths are inputted, multiplexes the inputted optical signals and transmits the wavelength multiplexed optical signal through a transmission characteristic compensator, transmission light amplifier 74 to which excited light is applied from an excited light source 70, and synthesizing/branching filter 93. A supervisory and controlling device 56 detects the level of the optical signal inputted to the wavelength multiplexer 91, counts the number of optical signals higher than a prescribed level and controls the excited light power of the excited light source 70 based on this counted result.  Thus, even when the number of wavelengths to be multiplexed is fluctuated, optimum control is enabled to the transmission level of the optical signal having each wavelength among the wavelength multiplexing optical signals outputted from the transmission light amplifier 74.
