Title: Servo-circuit of vtr
Inventor: KOBORI YASUNORI
IPC: H04N5/7826
Filed: 1978-09-18
Abstract: PURPOSE: To reduce a shift in tracking due to temperature variation and aging variation at long play by triggering a delay monostable multivibrator by a vertical synchronizing signal in a next period after a dividing monostable multivibrator is triggered.  
     CONSTITUTION: Vertical synchronizing signal 1 changes into division output 3 through dividing monostable multivibrator 2. On the other hand, output 29 with synchronizing pulse 1b sampled by gate 28 is inputted to switch circuit 6 together with division output 3. The output of switch circuit 6 is passed through a recording amplfier to record control pulses 9 and 9' on a magnetic tape. Then, division output 3 is supplied to drum sero-system 27 to perform phase control. At this time, the synchronizing pulse triggering delay monostable multivibrator 4 is pulse 1b in a next period when dividing monostable multivibrator 2 is triggered, so that delay value t' for obtaining control pulse 9' at long play will lessen.

Title: Fuel injection device
Inventor: TSUGE MASAKUNI
IPC: F02M45/00
Filed: 1991-04-19
Abstract: PURPOSE:To vary the fuel injection quantity suppression degree in accordance with the load by suppressing the fuel injection quantity at an early state of injection, suppressing the diesel knock, and reducing the quantity of NOx. CONSTITUTION:A passageway 13 for guiding a fuel to a spring chamber 10 is provided, and different-in-level surfaces 14a, 14b are provided in an end surface of a plunger 3. By provision of these different-in-level surfaces, when the plunger 3 has been lowered, the passageway 13 is closed later than a fuel supply passage 6. As a result, the pressurized fuel is accumulated within the spring chamber 10, so that, at the time when the valve is opened, the rising speed of a needle 7 is suppressed. Namely, the fuel injection rate during the ignition delay time length is supprised. Note that a position-level difference may be provided between the openings of the fuel supply passage 6 and the passageway 13, in place of said different-in-level surfaces. Further, the different-in-level surface 14b can be inclined with respect to the different-in-level surface 14a so as to vary the lag between the timings with which the supply passage 6 and the passageway 13 are respectively closed.

Title: Front body structure in automobile
Inventor: WATANABE MASAYA
IPC: B62D25/20
Filed: 1989-05-01
Abstract: PURPOSE:To improve the extent of rigidity in an engine room as a whole by forming a support part of a suspension tower in a part of wheel apron reinforcement and connecting the wheel apron reinforcement to a subframe extending in the car width direction. CONSTITUTION:As a support part of a suspension tower 6 is formed in a part of wheel apron reinforcement 8, push-up load out of a suspension is transferred to the wheel apron reinforcement 8 from the support part, absorbing it at an extensive part. Consequently, a reinforcing structure in and around the suspension tower 6 is securable without using any special reinforcing member and increasing the extent of body weight. In addition, since the wheel apron reinforcement 8 is connected to a subframe 14 extending in the car width direction as a reinforced member for an engine room 1, supporting rigidity for this subframe 14 is improved, thus improvement in rigidity for the whole engine room 1 is well promotable.

Title: Distance detector with deviation detecting function
Inventor: YOSHIDA SHIYOUZOU
IPC: G03B5/00
Filed: 1984-06-06
Abstract: PURPOSE:To use projector and receiver of light in common for detections of deviation and distance, by allowing distance detecting action at least two times, storing a signal obtained by the first detection and detecting the inconformity by comparing this result and a signal in the subsequent detection. CONSTITUTION:When a specific quantity of light signal O3 at the first measurement is not equal to that O3 at the second measurement (when a deviation is produced), a conformity detecting circuit 34 issues a signal of H-level into an AND gate 35 and when output pulses phi4, phi7 are being introduced, the gate 35 issues the signal of H-level into a driving circuit 36. Thus, the circuit 36 is brought to operation to ignite a light emission diode 37. While the diode 37 is on, objective patterns received by light receiving elements 2, 3 at light emission and receiving actions in 2 times are different, namely, suggesting generation of a deviation. Fluctuations of specific light quantity signal O3 is detected as a deviation also. By using in common light projector and light receiver for detections of deviation and distance, the deviation detection function can be accomplished by fulfilling the requirements for compactness and low-cost property.

Title: Optical head
Inventor: ITO NOBORU
IPC: G11B7/135
Filed: 1985-05-29
Abstract: PURPOSE:To arrange an optical system and an actuator on the same plane by detecting a focus and a tracking control signal by using a light beam branched between a collimator lens and a semiconductor laser. CONSTITUTION:The collimator lens 42 or semiconductor laser 40 is driven for focus or tracking control. When the distance between the semiconductor laser 40 and collimator lens 42 in the direction of the optical axis is varied to shift an aperture lens 43 in image formation point in the direction of the optical axial. Further, when the collimator lens 42 is moved vertically at right angles to the optical axis, the image formation point of the aperture lens 43 moves at right angles to tracks, so the focus or tracking control is performed by this method. When the collimator lens 42 is moved in the optical-axis direction, the aperture lens shifts in image formation point O', but the position of a conjugate image formation point O'' on a focus detector 47 does not shift in position in the optical-axis direction and defocusing is detected from the shift in image formation point O'' in the optical-axis direction. Consequently, the actuator is arranged on the same plane with the optical axis and an optical head is reduced in thickness.
