Title: Current limiting circuit
Inventor: TASAKA KAZUHIRO
IPC: H03F3/20
Filed: 1980-06-13
Abstract: PURPOSE:To save number of components by using one current limit transistor (TR). CONSTITUTION:When output TRs 25, 27 are in class B or in the vicinity, a current flows only to one of resistors 32, 33 between the emitter and an output terminal 28 of the TRs 25, 27, depending on the polarity of a current flowing to a load connected to the output terminal (output current). Thus, a voltage across the resistor, that is, a voltage between the emitter and the emitter of the TRs 25, 27 is that proportional to the absolute value of the output current, independent of the polarity of the output current. A current limiting TR 38 can be operated when the absolute value is more than a given value independently of the polarity of the output current, by dividing the voltage through resistors 34, 35 and applying the result between the base and the emitter of the TR 38.

Title: Ink jet printer
Inventor: TAKASU TAKUMA
IPC: B41J2/05
Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To enhance the dot diameter gradation by providing at least one counter electrode with a protrusion at a part thereof facing the other electrode while projecting to the other electrode side thereby increasing the variation rate of the quantity of ink droplet to be jetted. SOLUTION: A pair of counter electrodes 13, 14 are arranged in a pressure chamber and conducted with an electrode driver 17 thus generating boiling bubbles 22 in a conductive ink in the pressure chamber. The counter electrodes 13, 14 are provided, at the opposite end parts thereof, with arcuate parts A and linear parts B are formed continuously thereto. More specifically, the parts A are formed as close as possible while the parts B are formed to recede from the central part of the pressure chamber as they recede from the parts A. Since the current is concentrated between the protrusions of the electrode when a high voltage is applied and the current distribution is widened when a low voltage is applied, volumetric variation rate of boiling bubbles 22 is increased. Consequently, variation rate of the dot diameter is increased and the gradation is enhanced.

IPC: B65G35/06
Filed: 1984-04-19
Abstract: PURPOSE:In a conveyor for conveying articles such as clothes or the like, to prevent the articles from falling from the conveyor when the speed or the like is changed, by constructing the conveyor with running members for conveying artticles which run in parallel with each other in an endless manner and with pushing pieces driven by a chain, and by forming the track of the pushing pieces, at the corners, into an arc defined around the contact point between the running member and the pushing piece. CONSTITUTION:Each L-shaped pushing piece 19 attached to the lower end of an endless chain 6 is mounted rotatably to the axis 18 in the central portion of a running member 15. A pushing piece 18 is driven by the endless chain 6, so that the running piece 15 runs along and within a guide channel 13. When the chain turns along the circumference of a sprocket 9 at a corner (e), the running member 15 is kept stopped since the pushing piece 19 merely turns around the axis 18. Therefore it is possible, in this time, to engage a hanger with a hook plate 17 so as to change the direction of the hanger. According to this construction, articles can be prevented from being transferred when the speed or direction is changed and therefore from falling from the conveyor.

IPC: G08G1/14
Filed: 1989-03-30
Abstract: PURPOSE:To always accurately detect the presence or the absence of parking cars only by the data processing on a camera side and to simplify the maintenance management of a parking log by storing measured data for non-parking in each parking area as reference data, comparing actual measured data and this reference data with each other and discriminating the presence of parking cars at the time of the difference between them. CONSTITUTION:When any parking car does not exist in respective parking areas at all, the image of the parking lot is picked up by a camera 11 to obtain a two-dimensional image. Measured data at each measuring point of this image is stored as reference data in a reference data memory 21. Measured data at each measuring point of the two-dimensional image obtained by usual measurement executed at intervals of a certain period is compared with reference data at this measuring point by a CPU 19: and when the number of data different from reference data exceeds a prescribed value, the presence of parking cars is discriminated to output information indicating the presence of parking cars. Thus, the presence or the absence of parking cars is always accurately detected only by the data processing on the camera 11 side, and the maintenance management of the parking lot is considerably simplified.

Filed: 1996-04-02
Abstract: PROBLEM TO BE SOLVED: To surely suppress rotational vibration with a small sum of investment with a comparatively simple method even if an existed object is to be altered by feeding back a rotational vibration suppression signal to a clutch. SOLUTION: The rotational output speed of a reduction gear 3 containing rotational vibration generated by the reduction gear 3 is measured by a sensor 5.

IPC: H03H17/00
Filed: 1981-05-27
Abstract: PURPOSE:To use the titled circuit also as a circuit where variable data are inputted, by setting the maximum variation permissible value of input data stored in a memory to an optimum value. CONSTITUTION:Input data 1 is inputted through a receiver 2. At the same time, last input data 4 is read out of a buffer memory 3. This is inputted to a subtracter 8 to calculate the difference from the current input data 1. This difference is converted into an absolute value 10 by an absolute value circuit 9. This absolute value is compared by a comparator 12 with the maximum variation permissible value of the input data stored in a memory 11 and when the absolute value 10 of the difference between the 1st input data and current input data is less than the maximum variation permissible value, a gate 6 is opened to store the current input data 1 as real data in a main memory 7. When the absolute value 10 is greater than the maximum variation permissible value, the gate 6 is closed and the current input data 1 is not stored in the main memory 7.

Filed: 1982-05-11
Abstract: PURPOSE:To protect a data of an internal memory, by pulling up an address signal in a CPU card, and stabilizing a level of an internal bus. CONSTITUTION:A pull-up resistance 1e is installed to an internal bus 1d in a CPU card 10. Also, an internal memory 1b is protected at the time of DMA transfer between an external memory 3 and an input/output device 2 by pulling up an internal address signal in the CPU card and stabilizing a level of the internal bus. Accordingly, even if a signal in the output direction of a CPU1a becomes in a floating state, an address signal (1d-a) of the internal bus 1d is pulled up by the resistance 1e. Therefore, a level does not become unstable, and accordingly, the contents of the internal memory 1b are not broken down.
