Title: Method for averaging speed of variable power steering
Inventor: MAIKERU JIYON SHIYOOKII
IPC: B62D6/02
Filed: 1992-05-22
Abstract: PURPOSE: To provide a variable effort power steering system which can change steering effort in response to a control current under the control of a microcomputer. CONSTITUTION: A vehicle speed input signal is generated and a change in vehicle speed is detected 14 by periodically calculating vehicle speed samples from the speed input signal. Then a steering effort control signal is generated as the function of the calculated average speed. In the case of vehicle deceleration, a long averaging time is used to inhibit abrupt steering effort changes during braking. In the case of vehicle acceleration, a short averaging time is used for rapid response of steering effort to speed increases.

Title: Animation image retrieving device
Inventor: ARAKAWA HIROSHI
IPC: H04N5/7826
Filed: 1993-06-01
Abstract: PURPOSE:To provide an animation image retrieving device capable of accurately detecting a beginning desired by a user. CONSTITUTION:First, the user transmits a beginning fast forwarding instruction to a control part 3 by an input part 2, the control part 3 issues a reproduction instruction to a moving image storage part 1 and thus, reproduced animation images are inputted to a detection part 4, processed in a feature extraction part for respective frames and converted to the derivative of luminance inside the detection part 4. The derivative of the luminance is compared with the threshold value of a threshold value storage part by a comparator and when the derivative of the luminance is larger, it is judged as beginning detection and it is transmitted to the control part 3. When the control part 3 receives the beginning fast forwarding or beginning rewinding instruction from the input part 2 within a fixed period of time after receiving the beginning detection from the detection part 4, a threshold value changing instruction is outputted to the threshold storage part. The threshold value changing instruction is a decreasing instruction when the instruction is opposite from the previous instruction (beginning rewinding, etc., after beginning fast forwarding or the like).

Title: Current-interception device by detection of glow plug abnormality
Inventor: YAMAMIYA OSAMU
IPC: F02P19/02
Filed: 1982-07-27
Abstract: PURPOSE:To protect a glow plug current switching device by intercepting current from a glow plug for stopping abnormal excess current in case a voltage caused in a current-detecting resistance is within a fixed range for over a fixed time. CONSTITUTION:When a key switch 2 is on and even one of several glow plugs 4 in parallel is in low resistance, a voltage at b-point cannot reach to a voltage at c-point even after a long time, and consequently, the output of a comparator 6 cannot reach to an H-level. At this moment, the +input voltage of a comparator 10 is risen by a charging circuit of a resistance 9 and a condenser 8. When it comes to the voltage of a Zener diode 7, the output of the comparator 10 reaches to the H-level. Consequently, a relay drive circuit 15 supplying current since the key switch is on is off for preventing the long-time electrification by excess current.

Abstract: PURPOSE:To fix driving force and an elevating speed during lifting by moving driving a movable member in a horizontal direction, moving the inclined surface of the movable member by an elevating floor, to which wheels are fitted, and vertically changing the elevating floor. CONSTITUTION:When an elevating floor is lowered and a motor is rotated in a direction to extend a screw jack 17, a movable member 10 starts moving in the horizontal direction and wheels 12 of a movable frame 11 lowers on the inclined surface along an inclined rail of a guiding member 7. Then, the movable member 10 is displaced downward as well. On the other hand, wheels 15 of the elevating floor 3 loaded on an inclined rail 13 of the movable frame 11 fall down as well along the inclined surface with the move of the movable member 10. In order to raise the elevating floor 3, when the screw jack 17 is contracted and the movable member 10 is climbed up the inclined rail 8 of the guiding member 7 through the wheels 12, the wheels 15 of the elevating floor 3 also climbs up the inclined rail 13 of the movable member 10. Thus, since the respective inclined surfaces of the inclined rails 8 and 13 are fixed, the driving force and elevating speed are fixed.
