Title: Skew preventing mechanism for endless film
Inventor: TANAKA HIDETOSHI
IPC: G05D3/12
Filed: 1992-01-09
Abstract: PURPOSE:To prevent skew by cutting the edge surface of an endless film diagonally, making a lever which can reciprocate and displace come into contact with the edge surface, and operating a differential system by a difference in the skew speed and drive roller speed to displace a tension means. CONSTITUTION:The edge surface of an endless film 1 is cut by 2-5mm to an orthogonal line in a longitudinal direction, and a lever 9 is made to come into contact with the edge surface so as to rotate freely. Therefore, the lever 9 is moved to a continuous line from a dotted line with the movement of the film 1 in order. The rotational speed of the lever 9 is transmitted to a differential system 15 through a transmission belt 14. Moreover the rotational force of a drive roller 2 which carriers the film 1 is transmitted to the differential system 15 through a transmission belt 18. When the ratio between the rotational speeds of the lever 9 and the drive roller 2 deviates from a prescribed value, the differential system 15 rotates an output shaft 19 and the bearing 7 of a tension roller 6 is moved to B or in the opposite direction to change tension.

Title: Oscillating testing apparatus of acceleration and deceleration
Inventor: KUNISADA EIJI
IPC: G01M13/02
Filed: 1989-01-09
Abstract: PURPOSE:To improve the maximum generation angular acceleration of an output shaft thereby to make a testing apparatus compact in size by providing an oscillating slider crank mechanism between a driving shaft and said output shaft. CONSTITUTION:A sleeve-like slider bearing 25 is inserted coaxially into a hole 24 of a block-shaped slider section 23 formed in a room 17 of an output shaft 21. The bearing 25 supports a free end of a coupling rod 26 which couples a driving shaft 3 and the output shaft 21 in a manner to allow reciprocal movement of the free end. A base of the rod 26 is rotatably held by a crank pin 16. Thus, an oscillating slider crank mechanism is constituted between the shafts 3 and 21. The rod 26 is bored so as to reduce the moment of inertia. When a test piece is mounted in the shaft 21 via an attachment 27 and the shaft 3 is rotated so as to rotate the coupling part of the rod 26 and pin 16 around an axis of the shaft 3, the free end of the rod 26 reciprocates within the slider 23, thereby oscillating the slider 23. In consequence, the shaft 21 integrally formed with the slider 23 makes a reciprocal angular motion. Therefore, the moment of inertia to the shaft 21 is reduced, whereby the maximum generation angular acceleration is relatively raised.

Title: Control of flow rate with vvvf device
Inventor: SATOU KAZUYUKI
IPC: H02P5/74
Filed: 1980-01-14
Abstract: PURPOSE:To control a large capacity prime mover with a relatively small capacity VVVF device by controlling the prime mover in a pulse modulation to adapt it for a necessary flow rate characteristic and starting the prime mover alone by the VVVF device variable voltage variable frequency control. CONSTITUTION:In order to control a blower along a blast furnace duct production amount change pattern designated, for example, by A, the blower is controlled with a pulse waveform indicated by C. The blower is started under VVVF control, and after started, is controlled by the commercial frequency power source. After the system necessary for starting is isolated from the other system in controlling a plurality of prime mover system, it is started and controlled with the VVVF device. Since the main operation can be fully conducted with the commercial frequency power source with the above configuration, the efficiency of the prime movers can be performed at a maximum, and since the VVVF device is used only at the time of starting, it can have relatively small capacity.

Title: Hanger for brazing heat exchanger in furnace
Inventor: NONAKA MASARU
IPC: B23K1/008
Filed: 1989-01-09
Abstract: PURPOSE:To surely heat a tube plate and to improve reliability by brazing by projecting contact parts to come into contact with the tube plate rear surface on the upper surfaces of supporting bodies and forming the plural contact parts at an interval in the longitudinal direction on the supporting bodies. CONSTITUTION:The supporting bodies 4 made of round bar materials are fitted respectively to the inside of a U-shaped piece 12 and the upper surface of the supporting bodies 4 are cut down flatly except a part and bamboo nodular projections are formed only on the upper surfaces. The rear surfaces of a tube plate 2 of the upper surface side of cores 22 is supported on the couple of supporting bodies 4 and only the contact parts 5 of the projections formed on the upper surfaces of the supporting bodies 4 are brought into contact with the rear surface of the plate 2. In a furnace, when brazing material of the plate 2 and the other part surface is molten, radiant heat from a heater is radiated to the front sides of the cores from the diagonal direction between the respective cores. Since a hanger holds only the upper ends of the cores and does not cover the peripheries of the cores, the cores are not obstructed by the hanger and the radiant heat reaches the front side of every core by reflection and uniform heating is carried out.

Title: Electric vehicle controller

IPC: H01M10/48
Filed: 1996-01-11
Abstract: PROBLEM TO BE SOLVED: To enhance operability by restricting temporal change at the time of relaxing restrictions after restricting the output of a motor and preventing an electric vehicle from being abruptly accelerated at the same degree of opening of an accelerator. SOLUTION: In this electric vehicle control device, when the quantity of state monitored by quantity-of-state monitoring means 15 to 19 is changed beyond a limiting value, maximum output restricting means 25 to 28 give the restriction of a predetermined width to a maximum output computed by maximum output computing means 23, 24 to give it to motor output control means 33 to 35, thereby restricting the output of a motor. When the quantity of state is recovered into the range of the limiting value, the maximum output restricting means 25 to 28 relaxes restrictions to the maximum output computed by the maximum output computing means 23, 24, and however, at that time, limitation restricting means 29 to 32 restrict the temporal change in the direction of relaxing the restriction of the maximum output, which is performed by the maximum output restricting means.

Abstract: PURPOSE:To make the line width small and form many recessed grooves by a method wherein the recessed grooves are formed on a core and are filled by deposited and plated metal layers to form the spiral coil grooves in one united body and the number of the grooves is made coincide with that of rotary magnetic heads. CONSTITUTION:Spirally recessed grooves 4 are formed on a core by photoetching. A solution of more than 50% content of acid such as fluoric acid, hydrochloric acid and phosphoric acid is dripped into the grooves 4 and made react for approximately 20-60min and washed off by water. Then spirally recessed grooves 6 are formed on the core. The whole surface where the recessed grooves are formed is covered by a ground metal layer 7 such as copper or aluminium by vacuum deposition and dipped in a trichloroethylene solution or the like to remove a photoresist on the surface. The metal layer on the photoresist is, at the same time, peeled and removed and only the ground metal layers 7 in the recessed grooves 6 are left. Then the surfaces of the metal layers 7 are covered by metal layers such as nickel by electrolytic plating or non-electrolytic plating and the recessed grooves are filled. The same number of coils as of the rotary magnetic heads are formed on the disc-shape ferrite core.
