Title: Method for detecting movable object
Inventor: USAMI SUKEYUKI
IPC: H04N19/85
Filed: 1994-07-14
Abstract: PURPOSE:To extract the OPF of only a movable object even when structures (the handrail of a bridge, the support of a guard rail, etc.) appearing periodically in the background of an image exist when a movement vector (optical flow OPF) is calculated by a block matching. CONSTITUTION:The images A, B and C obtained by a camera 10 at time t0, t1 and t2 are supplied to an ECU 12. The ECU 12 calculates an OPFV 1 from the images A and B and calculates an OPFV 2 from the images A and C. The true OPF caused by a movable object or the false OPF due to a periodic structure is decided by depending on whether the lengths of the V1 and V2 are in the prescribed relation based on the time difference.

IPC: G06K15/10
Filed: 1983-09-02
Abstract: PURPOSE:To reduce the capacity of a character generator by a method in which printing patterns for contracted letters or characters are compiled and formed from usual letter patterns housed in the character generator. CONSTITUTION:Bit rows of matrixed bit array of usual letter pattern from a character generator 5 are written in the first register 17 in order. Odd-number bits and even-number bits are judged by a judgement means 18 and housed in the second register 19, and the first and second printing patterns for contracted letters are compiled and housed in RAM. A printing head drive circuit 8 is operated by the first controller 20, and letters or characters corresponding to the first printing pattern are printed. A printing paper is sent out by 1/2 of the interval of printing pins by the second controller 21. Afterwards, the letters of the second printing pattern are printed on the previously printed letters in a lapping manner by the first controller 20, and contracted letters are printed. The needs for character generator of large capacity can thus be eliminated.

Title: Control device for multi-room type air conditioner
Inventor: HIBINO YOZO
IPC: F24F11/02
Filed: 1994-07-14
Abstract: PURPOSE:To perform a more stable and accurate control of each of a discharging temperature and a room temperature by a method wherein a total amount of increasing and decreasing at a degree of opening of an indoor expansion valve required for controlling a discharging temperature at a compressor to its target value is calculated and there is provided means for adjusting the total value in response to a predetermined rate. CONSTITUTION:A target value determining mechanism 40 of a control device 30 determines a target value of a discharging temperature. In addition, a calculating mechanism 41 calculates a total amount of increasing or decreasing at a degree of opening of an indoor expansion valve in such a manner that a difference between the determined target value and a detected value detected by a discharging temperature sensor 24 may be decreased. In addition, an adjusting and calculating mechanism 42 distributes the calculated total amount to an increased or decreased amount of the degree of opening at the indoor expansion valve in each of the rooms. In turn, at each of the rooms, a room temperature setting value is set with a room temperature setting device 28. Then, either a temperature difference of the refrigerant at an inlet or outlet passing through the indoor heat exchanger 20 or an air supplying or air discharging temperature difference is controlled in response to a difference between the set value of the room temperature and the detected value so as to control an air controlling capability at the indoor heat exchanger 20.

Inventor: SATO JUN
IPC: B65H15/00
Filed: 1999-06-09
Abstract: PROBLEM TO BE SOLVED: To prevent occurrence of re-transposition scumming due to undried ink in the case of resupplying a one-side printed sheet and double-side printing, to shorten a waiting time from an end of the one-side printing to the resupplying, and to prevent a decrease in image quality due to an ink insufficiency on a printing surface of the one-side printed sheet.

Title: Noise reducing circuit for semiconductor laser
Inventor: SAKURAI TATSUAKI
IPC: G11B7/125
Filed: 1989-06-23
Abstract: PURPOSE:To sufficiently reduce noise by detecting modulation factor of a semiconductor laser driving current when a high frequency superposing circuit is turned OFF, and controlling a high frequency current superposing amount according to the modulation factor. CONSTITUTION:When a high frequency current superposing circuit 12 is turned OFF by a high frequency superposing ON/OFF signal, only a DC current by a semiconductor laser driving circuit 13 flows to a semiconductor laser 11. Further, a holding circuit 16 becomes a holding mode to hold an output signal of a control circuit 15 immediately before the mode. The light emitting amount of the laser 11 is detected by a photodetector 14, and this detection signal is input to a modulation factor control circuit 17. The circuit 17 compares the light emitting amount of the laser 11 when a high frequency current is superposed on a DC current with a light emitting amount of the laser 11 when it is not superposed to control the circuit 12 when the former is not sufficiently smaller than the latter, thereby so regulating it as to increase the superposing amount of the high frequency current. If the former is excessively smaller, the circuit 12 is controlled to reduce the high frequency current. Then, the circuit 12 is turned ON to control the light emitting amount of the laser 11.

IPC: C02F3/08
Filed: 1987-07-01
Abstract: PURPOSE:To decrease the weight of a rotating body and to prevent the damage of a bearing by providing a float to the rotating body. CONSTITUTION:A shaft 1a of the rotating body 1 having contact materials 2 for sewage treatment is supported by bearings 5 in such a manner that said shaft can be freely rotated by means of a bearing device 6. While this rotating body 1 is kept immersed in the sewage, the org. matter in the sewage sticking to the surface, etc., of the rotating body 1 is brought into contact with the air to promote the propagation of aerobic microorganisms and to decompose the org. matter, thereby cleaning the sewage. Large buoyancy is acted on the rotating part immersed in the sewage by floats 3 disposed at both side ends of the rotating body 1. As a result, the weight of the rotating body 1 is greatly decreased and the load acting on the bearings 5 is decreased as well and, therefore, the failure of the bearings 5 by the weight of the rotating body 1 is prevented.

Filed: 1986-07-10
Abstract: PURPOSE:To convey sheets of paperboard along an upward gradient securely with a minimum distance in a condition of dominoes fallen forward by employing a conveyer having a curved conveying surface with its gradient gradually decreasing toward a discharge end. CONSTITUTION:A pressure cylinder device 38 is actuated, a stopper 37 is lowered as far as it is hidden in a conveying surface of a conveyer 44 while the stopper 37 is supporting sheets of paperboard 6 in a condition of dominoes fallen forward, and the sheets of paperboard 6 take an attitude of dominoes fallen forward. When the descent of the stopper 37 is finished, drive devices 32, 36 and 47 are operated and a send-out conveyer 31, a kicker 33, a bottom conveyer 35, and conveyers 44 and 46 respectively advance at high speeds. This transfers the paperboard sheets 6 from the conveyer 44 to the conveyer 46 in succession. Since a conveyer belt 443 advances along a curved plate 43 in the conveyer 44, the conveying surface of the conveyer 44 gradually reduces its gradient toward a discharge end 442 becoming approximately level at the discharge end 442.
