Title: Optical track tracing device
Inventor: YASUDA KENICHI
IPC: G11B7/09
Filed: 1987-05-21
Abstract: PURPOSE:To obtain an accurate track deviation detection signal by correcting the track deviation detection signal due to a first light receiving part for track deviation detection by the medium inclination detection signal due to a second light receiving part. CONSTITUTION:First light receiving parts 10a and 10b of a photodetector for track deviation detection are arranged for a totally diffracted luminous flux 17, and second light receiving parts 18a and 18b of a photodetector for medium inclination detection are arranged in the area to which the diffracted luminous flux 17 is not projected. That is, not only the totally diffracted luminous flux 17 is moved in parallel but also the distribution of light intensity of this luminous flux 17 is changed when the medium is inclined. Consequently, the differential output signal of light receiving parts 10a and 10b of the photodetector for track deviation detection is corrected with the differential output signal of light receiving parts 18a and 18b of the photodetector for medium inclination detection, and the latter differential output signal is controlled to a minimum. Thus, stable track deviation control is performed.

Title: Automatic cotroller for retarder brake
Inventor: WATANABE MASAHIRO
IPC: B60T10/00
Filed: 1980-09-04
Abstract: PURPOSE: To control the retarder brake easily by controlling sped by means of the brake, weakening braking force in response to the temperature of brake oil and preventing the overheat of the retarder brake.  
     CONSTITUTION: Set car speed signals by a car speed controlling lever 1, brake oil temperature signals from a temperature detector 5, actual car speed signals from a speed detector 6 and variable speed stage signals-overrun signals from a transmission controller are inputted to the controller 30. The controller 30 outputs signals controlling the force of the retarder brake on the basis of deviation between actual car speed and set car speed while weakening the force of the retarder brake when the temperature of the brake oil exceeds set value to lower the temperature of the oil. Accordingly, since the retarder brake is controlled in response to car speed, operators may operate only a steering, and safety is improved.

Title: Running cource indicator
Inventor: TAGAMI KATSUTOSHI
IPC: G01C21/28
Filed: 1980-09-04
Abstract: PURPOSE:To prevent the occurrence of an errorneous guidance, by a method wherein, when a change in an offset output of a sensor due to an extroadinary generation of temperature in a gas rate sensor housed in a constant temperature oven is detected, an alarm is generated. CONSTITUTION:Outputs from a gas rate sensor 2, housed in a constant temperature oven 1, and a distance sensor 3 are inputted to and operated at a signal processor 4, and an indicator 5 indicates a running cource of a running object. An energizing  controller 8 controls the connection of a power source E to the constant temperature oven 1 through the working of an ignition switch IG.SW, a power source circuit 7, and a control panel 6. The offset signal of the sensor 2 produces a given reference value at a time when the running object stops, but the internal temperature becomes abnormal. If the offset signal does not coincide with the reference value, an alarm indication is conducted in an indicator 5. This prevents the occurrence of an erroneous guidance.

Simultaneously, a pulse from an FF17 is inputted to a latch circuit 19, the count value of the counter 16 is inputted to an indication circuit 20, and a running distance per 1l of consumption fuel. This facilitates reading of an indication value, simplifies a device, and reduces a manufacturing cost.

Title: Flow control valve
Inventor: YONEDA KOUHEI
IPC: F16K17/06
Filed: 1979-09-26
Abstract: PURPOSE: To let an oil hydraulic cylinder operate smoothly and quietly during the contraction stroke by giving damper action to the sliding of a balance piston of a flow control valve to be installed in the operating circuit for the cylinder.  
     CONSTITUTION: When a directional control valve V is shifted to the left, the self- weight of a dump trick's rear body presses forward the working oil at the high pressure side of an oil hydraulic cylinder C to a ring passage 7 through an outlet port 4, a fixed orifice Of, the inside of a balance piston 9 and a variable orifice Ov, and then the oil is returned to the oil sump T through the directional control valve V. Because, at this time, the self-weight of dump truck's rear body produces a differential pressure at the oils fore and behind the orifice Of, the balance piston 9 slides toward the inner end and reduces the opening of orifice Ov. This sliding of balance piston 9 reduces the effective capacity of oil pressure damping space 11 and lets thereby the pressure oil inside go out through a restrictor hole 12. Because this pressure oil receives the restriction resistance at this time, the balance piston 9 is given damping action.
