Title: Travelling apparatus of agricultural tractor
Inventor: KATAYAMA YOSHIYUKI
IPC: B60K23/08
Filed: 1981-06-08
Abstract: PURPOSE:To enable a tractor to turn with a small radius without lowering the speed thereof, by changing the rotational speed ratio of steering wheels to steered wheels to specified value. CONSTITUTION:Hydraulic motors M1, M2 for driving the steering wheels and steered wheels 5, 5, 9, 9 are connected respectively to first and second hydraulic pumps P1, P2 and an apparatus 14 for automatically controlling a flow rate regulating valve 11 is provided such that the difference of the rotational speed of the right and left wheels 5, 5 corresponds to the steering angle of the wheels 5, based upon the informations from an apparatus 12 for detecting the rotational speed of the wheels 5, 5 and an apparatus 13 for detecting the steering angle of the wheels 5. Further an apparaus 18a which is capable of changing the rotational speed ratio of the wheels 5, 9 is provided between the pumps P1, P2. Thus, the rotational speed ratio can be finely changed in accordance with the steering angle of the wheels 9 so that the greater the steering angle of the steering wheels 5 is, the greater the rotational speed of the wheels 9 is, and therefore the rotational speed thereof can be kept at not less than that at the straight travelling.

IPC: G06F9/44
Filed: 1990-04-02
Abstract: PURPOSE:To easily change function characteristic with simple configuration by comprising a membership function generation circuit of an actuating amplifier circuit. CONSTITUTION:The actuating amplifier circuit with emitter resistor is used as the membership function generation circuit, and a working pair of NPN bipolar transistors Q1, Q2 are used as an amplification element. In such a case, an input voltage is supplied as (VIN-VREF), and an output voltage V01 for the input voltage (VIN-VREF) corresponds to a Z function in fuzzy logic, and an output voltage V02 corresponds to an S function. Furthermore, different characteristics for the inclination of a variation straight line in straight line follow-up range A can be obtained by setting a constant current Io and emitter resistors RE1, RE2 arbitrarily. In such a way, it is possible to obtain a membership function generator in which variable characteristic can be realized with comparatively simple configuration.

Title: Bus control system
Inventor: NAKAJIMA YUTAKA
IPC: G06F13/368
Filed: 1983-05-19
Abstract: PURPOSE:To acquire buses at a high speed by setting a proper bus acquisition request line in a significant state while a busy signal line corresponding to the bus aquisition reuests of plural modules is showing no busy state. CONSTITUTION:The modules are connected with a general-purpose bus 27 for memories M21-M23 and input/output processors P24-P26, respectively. The bus 27 contains exclusive bus acquisition request signal lines 31-36 which transmit bus acquisition request signals r1-r6 of M21-M23 and P24-P26, respectively, busy signal lines 41-45 which transmit exclusively busy signals b1-b5 corresponding to the types of bus acquisition requests, and a bidirectional data line 51. When each module has a bus acquisition request, the states of lines 41-45 are decided in accordance with the types of requests. The proper lines 31-35 are set in significant states when no busy state is shown. Then the bus acquisition is carried out from own module to a module of higher priority while the lines 31-35 are not in significant states. Then the access request data is sent to the line 51.

Title: Magnetic recorder/reproducer
Inventor: SHIBATA AKIRA
IPC: G11B20/02
Filed: 1979-07-13
Abstract: PURPOSE:To attain sharp reduction of the cost by obtaining the crystal oscillator necessary for the reproduction plus the ringing oscillator necessary for the record respectively. CONSTITUTION:Power terminal T6 of the VTR always receives the supply of 12V; whill 12V is supplied to terminal T7 only when the recording is carried out. In the cases other than the above, OV is supplied. In other words, terminal T7 features 12V at the recording time to cut off diode D1.  And the output signal sent from terminal T8 is applied to the burst gate amplifier (not shown in the figure) to excite crystal 15, and thus the color killer voltage of about 10V is generated at terminal T9. Terminal T7 turns to OV when the reproducing is carried out, and thus positive feedback loop from the emitter of transistor Q5 to transistor Q1 operates to obtain the continuous wave of about 2VPP at the emitter of transistor Q5. In such way, the crystal oscillator necessary for the reproduction is used in common to the ringing oscillator necessary for the record. Thus the color killer voltage can be produced assuredly to be used at the recording time just by using a simple amplitude wave detector. As a result, a sharp cost reduction is attained.

Filed: 1983-05-20
Abstract: PURPOSE:To prevent toner blocking from occurring by arranging a screw conveyor at the upper part of the gap between a photosensitive body and the magnet roll of a developing device, and removing successively toner which tend to accumulate over the gap. CONSTITUTION:The screw conveyor 9 arranged at the upper part of the gap between the photosensitive body 1 and the magnetic roll 3 of the developing device 2 rotates by receiving driving force based upon the rotating force of the photosensitive body 1 through a driving roll provided at the end part of the conveyor.

Title: Bearing device
Inventor: KAWAMOTO OSAMU
IPC: H01Q1/12
Filed: 1990-04-05
Abstract: PURPOSE:To enable use with high precision at various environmental temperature by putting a rolling element between inner and outer rings whose one end is engaged with a rotary shaft and the other end is engaged with a support body in play, and energizing the inner or outer ring with which rotary shaft is not engaged in specific direction. CONSTITUTION:A bearing 10 is pressed on and supported by a support body 12 when its outer ring 11b is energized by a plate spring 14. When environmental temperature changes, space 13 which exists between the outer ring 11b and support body 12 is changed due to difference of coefficient of thermal expansion of the bearing 10 and support body 12. However, the bearing 10 is pressed on and supported by inner wall of the support body 12 because the outer ring 11b is moved and energized by the plate spring 14. Even if load such as impact is applied, the plate spring 14 bends, and is not broken because it is made of metal. Thus, it is possible to realize support of rotary shaft with high precision without being affected by changes of temperature.
