Title: Control device for front and rear wheel steering vehicle
Inventor: IO SHINICHI
IPC: B62D101/00
Filed: 1990-08-07
Abstract: PURPOSE:To surely perform safe running without needing a complicated control circuit by mechanically increasing a steering amount, provided on rear wheel by a rear wheel steering angle providing means, to a transmission ratio, ranging from 0 to l, according to a steering amount of front wheels. CONSTITUTION:The target steering angle of rear wheels is computed by means of a steering angle 26 of front wheels and a car speed 27, and a motor 29 for steering is run. In which case, when a relative angle between a cam groove 40A of a slider member 40 and a cam groove 44A of a fixed block member 44 secured to an actuating rod 25 is 90 deg. in the neutral position of a steering wheel 16, a steering angle amount by rotation of the motor 29 for steering is not transmitted to the actuating rod 25. Reversely, when the relative angle is 0 deg., a steering amount by rotation of the motor 29 for steering is all transmitted as movement in a direction extending along an axis L1 of the actuating rod 25. As a result, mechanical regulation is carried out such that during linear running of a vehicle, the steering angle of rear wheels is adjusted to 0, when the steering angle of front wheels is low, the steering angel of rear wheels is decreased, and when the steering angle of front wheels is high, the steering angle of rear wheels is increased.

Title: Control method for driving of magnetic tape
Inventor: YAMAJI IWAO
IPC: G11B15/30
Filed: 1989-08-10
Abstract: PURPOSE:To use even a thin and long magnetic tape by using a non-contact slipping clutch in driving the rotating shaft of a reel. CONSTITUTION:Magnetic tapes 7, 7' are fed at a constant speed at all times by being held between driving rotary shafts 5, 5' and rubber rollers 1, 1'. Reels 6, 6' are quickly rotated when the magnetic tapes 7, 7' are wound less and slowly rotated when wound much, and the rotation difference thereof is absorbed by a non-contact slipping clutch. Namely a fixed disk 13 is given with its rotation power from a motor, the rotation is transmitted to a moving disk 13' by the mutual attracting powers of the magnets 12, 12' imbedded in the fixed disk 13 and moving disk 13', the reel rotary shafts 2, 2' provided at the tip thereof are rotated and the magnetic tapes 7, 7' are wound. The transmission force of the non-contact slipping clutch varies by the distance with the fixed disk 13 with the moving disk 13' being moved to the right and left. Thus the magnetic tapes 7, 7' can be thinned and the use of a long time type is made possible.

Title: Traction control device for vehicle
Inventor: IWATA TORU
IPC: B60W10/18
Filed: 1989-08-14
Abstract: PURPOSE:To prevent aggravation of straight running property due to unbalanced brake force by providing a setting value separating means to lower the setting value of a driving force lowering means than the setting value of an automatic brake means at high vehicle speed range. CONSTITUTION:When driving slip (d) of driving wheels (a) are over respective setting values (g1, g2), an automatic brake means (b) brakes driving wheels (a), a driving force lowering means (c) lowers the driving force generated with an internal combustion engine, and thus traction control is performed. At a high vehicle speed range detected by a vehicle speed detecting means (e), a setting value separating means (f) lowers the setting value (g2) of the driving force lowering means (c) than the setting value (g1) of the automatic brake means (b), and the partial charge ratio of traction control of a drive wheel brake is lowered than the partial charge ratio due to wheel driving force lowering. Hence, a fall of straight running property by unbalance of right and left brake force due to excess braking effect can be prevented.

IPC: H04N1/21
Filed: 1986-09-05
Abstract: PURPOSE:To contrive miniaturization and to offer a moving picture in addition to a still picture as well by using a disk device having plural read heads for the titled picture responding device. CONSTITUTION:When a call comes from a terminal equipment, a control section 1 finds out a dead head, and an exchange section is switched to send picture information read by the head to a line, thereby connecting the line to one of the heads directly. Thne the control section 1 controls each head so as to extract required picture information according to a pattern sending request from the terminal equipment and sends the picture information to the line in the form of the standard TV signal. In case of a still picture signal, the same picture information has only to be extracted at all times and then the switching section switching the connection between one head and plural frame memories and a conventional frame memory are not required. Moreover, since each head corresponds to the line one by one, the picture information of even a moving picture is read at high speed.

Title: Variable automatic centrifugal clutch equipped with toggle joint
Inventor: ISHIHARA TAKEO
IPC: F16D43/12
Filed: 1981-12-23
Abstract: PURPOSE:To enable to freely change the speed change point to shift to high speed gear in accordance with running conditions by a structure wherein the amount to be compressed of a spring is changed by utilizing the toggle joint in order to control the centrifugal force of a weight. CONSTITUTION:A pawl arm 171, which actuates when a throttle is open wider than a set opening degree, is engaged with the ratchet 146 of a cam mechanism 4. A braking action is applied to a driven cam 142 through a face plate 149 due to the stop of the rotation of the ratchet 146 caused by said engagement. A rotary cam 141 and the driven cam 142 are circumferentially displaced each other by means of said braking action, resulting in rolling up a ball 144 along the tapered groove 143 of the cam 142 and consequently causing to shift the rotary cam 141 onto an axle 13 so as to compress the spring 152. Accordingly, the engagement of the automatic centrifugal clutch 7 becomes impossible unless a first shaft 5 is run at a speed higher than the speed during normal running.

Filed: 1983-11-07
Abstract: PURPOSE:To improve the operability with simple constitution and to promote miniaturization further by providing a lock member and a slide switch member to a reel shaft being slidable in the axial direction. CONSTITUTION:A reproducing operating lever 20 is depressed, thereby causing a lock lever 74 and a switch lever 75 to be depressed and turned. Then, the operating lever 20 is locked at the operated position. The switch lever 75 turns on a leaf switch 76 in this case, causing a motor 43 to be driven. Then, a flywheel 44 turns a reel cap 51. In depressing a rapid traverse operating lever 21, the reel cap 51 is depressed and a lock member 54 is brought into contact with a bearing member 48. The switch lever 75 is depressed by the member 50 in this state and then the lever 74 is engaged with the lock member 50, causing the leaf switch 76 to be turned on and a reel shaft 16 to be locked. In this case, a rotating shaft 161 is lowered. Thus, the torque of the flywheel 44 is delivered to the reel cap 51 via gears 47, 58 and 53 and the rotating shaft 161.

Title: Disk controller
Inventor: FUJIOKA YOSHIO
IPC: G06F3/06
Filed: 1988-08-23
Abstract: PURPOSE:To prevent occurrence of waiting time for rotation caused by an ID section reading-out error by not performing data writing in a disk device, but saving the data to a memory means when positional collation is unsuccessful and writing the data saved to the memory means in the disk device after completing a series of writing operations. CONSTITUTION:At the time of writing data in a disk device 2, writing operations are started after a position detecting means 3 detects that a recording and reproducing means reaches a prescribed position on a recording medium, and when collation of an ID section is unsuccessful, the data writing in the disk device 2 is stopped, but the data are written in a memory means 6 for preservation. The data saved to the memory device 6 are transferred to the disk device 2 after a series of writing operations are completed. Because of the above-mentioned operations, a host device can write data in the disk device 2 at the same transferring speed as that exerted when ID section collation is successful even when the ID section collation is unsuccessful. Therefore, waiting time for rotation caused by an ID section reading-out error does not occur.
