Title: Bound bundle conveying roller conveyor
Inventor: IDEI MASARU
IPC: B65G13/02
Filed: 1997-07-10
Abstract: PROBLEM TO BE SOLVED: To suppress the damage of bound wires while maintaining durability of carrier rollers by providing oscillating bodies that can oscillate around horizontal shafts orthogonal to a conveying direction, and arranging the carrier rollers upstream and downstream in the conveying direction with the oscillating center placed in between. SOLUTION: A bound bundle T of a plurality of long-sized material 2 bound with annealing wires (binding wires) 1 is conveyed in an X-direction. Oscillating bodies 5 are oscillatingly arranged above a plurality of frames 3 fixed to a floor face, through horizontal shafts 4, and a pair of carrier rollers 7, 8 are rotatably fitted to the upper face of each oscillating body 5. Each oscillating body 5 is energized into a neutral position by rubber cushions 6, and the oscillating body 5 is held without tilting in the state of the annealing wire 1 not being in contact with any one of the carrier roller 7, 8. When the annealing wire 1 comes in contact with the carrier rollers 7 during conveyance, the carrier roller 7 is pressed by the annealing wire 1 so as to descend.  At the same time, the oscillating body 5 is rotated around the horizontal shaft 4, and the carrier roller 8 ascends by the descent part of the carrier roller 7 so as to relax impact caused by stranding of the annealing wire 1.

Title: Generating circuit of reference voltage
Inventor: SHINOMIYA KOUJI
IPC: G05F3/30
Filed: 1982-11-16
Abstract: PURPOSE:To obtain a stable reference voltage generating circuit even when power supply voltage is lower than the externally applied voltage of a energy band gap. CONSTITUTION:Resistors R6-R14 have functions operating a current mirror stably. A starting circuit consisting of resistors R4, R5 and TRs Q14, Q15 starts to operate ''a circuit creating current proportional to absolute temp.'' and current proportional to the absolute temp. flows out from respective collectors of the TRs Q4, Q5. The collector current of the TR Q4 causes the current with negative temp. factor due to the base and emitter of a TR Q13 to flow out from the collector of the TR Q13. Consequently, the added current of said two kinds of current flows into a resistor R3, and even when the power supply voltage is less than the voltage (1.205V) of the energy band gap of a semiconductor, stable reference voltage is obtained from a terminal T3.

Title: Vector pattern input device
Inventor: SAKO KAZUYA
IPC: G06K9/62
Filed: 1986-08-29
Abstract: PURPOSE:To obtain a simply structured, inexpensive character input device by providing a means that recognizes an inputted character pattern judging from a moving direction, moving time and moving sequence, all of which are detected by a detection means that has an operating plate for character input and detects the moving direction of the operating plate. CONSTITUTION:The operating plate 13 can move in eight directions on a same plane, and its moving direction is detected by turning on one or two among switches SW1-SW4. They are switches with fine strokes, and fixed on the four sides of the operating plate 13 or fixed on the side of an enclosure. Consequently an operator's finger hardly feels the movement in the direction even if it presses the operating plate 13. A switch input system comes in a static type employing only an input port and a dynamic type outputting a timing signal from an output port. A microprocessor MPU processes the inputs of the switches SW1-SW4 and controls the loads of a plunger PL, an LED or the like. A pull-up resistance R and a capacitor C prevent chattering.

Title: Film feeder
Inventor: NISHIO TETSUYA
IPC: G03B17/00
Filed: 1988-08-16
Abstract: PURPOSE:To prevent a film from being pulled out of a cartridge by switching and connecting a motor used for driving a power transmission mechanism to a constant voltage generating means from a fluctuating voltage power supply such as a battery according to the reduction ratio or value of a power supply voltage in the power supply transmission mechanism used for feeding a film.

At the voltage of the battery V2 which is equal to or higher than the prescribed value at the time of winding a film, the feeding power supply of a motor M1 is switched from the battery V2 to a DC/DC converter as a constant voltage generating means, and a motor M1 is driven at a constant voltage which is lower than the voltage of the battery V2. At the voltage of the battery V2 which is equal to or lower than the prescribed value at the time of winding a film, the feeding power supply of motors M1, and M2 is switched from the constant voltage device to the battery V2. Thus, a film is prevented from being pulled out of the cartridge.
