Title: Suspension device for automobile
Inventor: KANAI MASAHIRO
IPC: B60G17/00
Filed: 1984-03-19
Abstract: PURPOSE:To make improvements in both steering and driving characteristics, by adjusting a car level according to a car speed, while varying the size of a camber angle and a variation in time of bump rebounding according to this car-level control. CONSTITUTION:In time of car-level driving, when a car speed is less than the specified car speed Vo, by way of example, output of a comparator 43 receiving the output of a car speed sensor 41 is off, causing relays 39 and 40 to be turned to OFF. Therefore, the output of a car level sensor 31 is compared with each output of each of Ll and Lh signalers 35 and 37 at comparators 33 and 34, and a selector valve 24 is controlled by each output of these comparators 33 and 34. That is to say, a car level is kept in a high position in a range from an upper limit value Lh to a lower limit value Ll with operation of a car-level controlling cylinder 10 where pressure oil is supplied or drained via the selector valve 24. And, at this time, since length of an upper suspension arm 5 is made to be longer than that of a lower suspension arm 4, wheels 2 are given a camber angle variation so as to increase a positive camber angle.

Title: Panel opener
Inventor: SHIBUYA YASUSHI
IPC: G11B33/02
Filed: 1996-03-11
Abstract: PROBLEM TO BE SOLVED: To prevent a lock member from locking a panel again by quickly rotating the panel in the panel opening direction when the panel is unlocked. SOLUTION: When a panel 30 is unlocked from a lock member 35, it rotates by the force of a biasing member in a direction α1 such that a noncoupling hole 32c of the panel 30 slides a pin 41b to quickly rotate up to an angle θ, without receiving the resistance of a damper 43, then the edge of the hole 32c is coupled with the pin 41b to rotate a sector gear 41, together with the panel, causing the damper 43 to be driven to slowly rotate the panel. Since the panel 30 initially quickly rotates when being unlocked, the panel is never locked again by the lock member 35.

Title: Light recording medium
Inventor: TOGAMI YUUJI
IPC: G11B7/24
Filed: 1979-05-04
Abstract: PURPOSE: To uniformize the recording sensitivity of a recording layer on the whole surface, by coating a dielectric film of uneven film thickness on the recording layer using light.  
     CONSTITUTION: In forming a recording layer by a sputtering method or the like using a Gd-Co alloy target, the Gd composition ratio tends to increase with approaching the center in the Gd-Co film produced through the alloy to be used is uniform. When recording is carried out on such a film using laser beams, temperature distribution in the film is caused, and form and size changes in the region of HC<HT, where external magnetic field force and demagnetizing force are HT and coercive force is HC, resulting in making good recording difficult. Since it is difficult to uniformize the internal composition, the following treatment is made: A mask, such as a photoresist is formed on this film, and a dielectric film different in film thickness is coated to uniformize a total exposure quantity to the Gd-Co film.

Title: Ion printer
Inventor: OYAMA MASAHARU
IPC: B41J2/415
Filed: 1988-03-08
Abstract: PURPOSE:To prevent the generation of the irregularity of an electrostatic latent image by making the quantity of the ion accumulated on a dielectric drum constant, by controlling the time applying voltage to a control electrode corresponding to the output signal of an ion detector for detecting the quantity of the ion from an ion generator. CONSTITUTION:When an image data generator 10 drives a driver IC 9 according to predetermined image data, the driver IC 9 performs selective operation so that the potential of the second power supply 11 is applied only to a pattern electrode 7, to which the voltage corresponding to the image data must be applied, for a predetermined time. When the quantity of the ion generated from a corotron 1 is larger than a standard value, an ion detector 14 generates a signal shortening a voltage applying time to an applying time control apparatus 15 which in turn shortens the current supply time of the driver IC 9. Contrarily, when the quantity of the ion is less, the current supply time of the driver IC 9 is made long. Therefore, the quantity of the ion passing through a hole 6 becomes equal to that when the quantity of the ion generated from the crotron 1 is the standard value and the quantity of the ion accumulated on a dielectric drum 12 becomes constant.

Abstract: PURPOSE:To suppress the suction of a floor nozzle on a plane to be cleaned without lowering depth part suction performance by providing a valve traveling corresponding to the suction negative pressure of a suction room and a detecting means to detect the amount of travel of the valve, and decreasing the input power of an electric blower when the suction negative pressure is increased. CONSTITUTION:When cleaning is performed on the plane such as a flat plane to be cleaned where the floor nozzle is easy to suck such as a carpet, etc., the floor nozzle tries to suck by a strong suction force. At this time, the suction negative pressure of the suction room is highly increased, and the valve 21 travels against the pressure of a spring 22, and the resistance value of a variable resistor 24 connected to the valve 21 is changed, correspondingly, the charging speed of a capacitor is controlled, which decreases the input voltage to the electric blower, then, the suction force is decreased. Thereby, it is possible to improve operability without lowering the depth part suction performance.

Abstract: PURPOSE:To promote the improvement of quality of a product and life of a cutter blade, by measuring width of a steel plate, before it is cut, and controlling a circumferential speed of a milling cutter so that its cutting thickness per one blade obtains the best value. CONSTITUTION:A feed speed F of a steel plate 2 and a distance t1 from a center line 5 of the steel plate 2 to its edge, before the steel plate 2 is cut, are measured by measuring devices 3, 6 being input to an arithmetic unit 4. The arithmetic unit 4 also inputs constants C1, C2, determined by cutter specification of an outside diameter D of a cutter 1 and its number of blades or the like, and a finish width t2 from the center line 5. And the arithmetic unit 4, calculating a circumferential speed V of the cutter 1 so as to obtain the circumferential speed V=(C1F/SG)[1-(1-2t/C2)<2>]<1/2>, controls a rotary speed of a motor 9 of the cutter 1 (where SG shows the best cutting thickness per one sheet of cutter blade). And the cutter 1 is set so as to cut the plate into finish width 2t2. The steel plate width t1 and the feed speed F are measured in a fixed interval. Accordingly, the steel plate can always be cut in the best condition.
