Title: Parallel moving method for pallet type spiral conveyor
Inventor: ITO AKIRA
IPC: B65G17/18
Filed: 1985-12-03
Abstract: PURPOSE:To prevent occurrence of accidents due to inclination by incorporating such a construction that each pallet coupled with a chain makes parallel slide on a slide rail, wherein the horizontal holding member for elevation serves elevating portion, the horizontal holding member for descent serves descending portion, and the bottom surface between the two members serves level motion. CONSTITUTION:A horizontal holding member for elevation 71a at the bottom of each pallet 70 is arranged outside the pallet 70 while a horizontal holding member for descent 71b inside the pallet 70 so that it takes level attitude. Accordingly the pallet 7 makes parallel motion with the aid of a slide rail 72 wherein the horizontal holding member for elevation 71a slides up on the oversurface of said slide rail in the rising portion while the horizontal holding member 71b for descent 71b slides down on the oversurface of the slide rail in the sinking portion. In the level motion portion the oversurface of the slide rail 72 slides on the pallet bottom surface between the two holding members 71 so as to hold the pallet 70 in level and transport it. Thus pallets can always be held horizontal to ensure that transportation be made without risk of spilling- off of fluid substance or causing harm to the objects.

Title: System of driving bi-stable semiconductor laser
Inventor: TOMITA AKIHISA
IPC: H01S5/06
Filed: 1984-12-24
Abstract: PURPOSE:To enable high-speed response by a method wherein reset pulses in the deep negative direction which give a smaller gain than the loss Lsat when saturable absorption is saturated are impressed on the titled device. CONSTITUTION:Forward current is injected to an electrode 102 of a bi-stable semiconductor laser 1, and the reverse current from a pulse generator 3 is impressed via DC cut-off filter 4 on an electrode 101 in addition to forward current. For example, when the initial state 201 is I1=34mA, in the case of the photo input of 82muW, the semiconductor laser 1 starts oscillation at a point less than a rise delay time of 1n S. The semiconductor laser 1 is reset by im pressing a pulse current of 2n S width and -20mA from the pulse generator 3 synchronized with a clock pulse source 2. This causes the current injected from the electrode 101 to be 14mA, smaller than a point of intersection A of the extension of the upper branch of the hysteresis with L=O. The fall delay pulse can be set at less than 1n S by using a large reset pulse 203.

Title: Steel plate takeup machine
Inventor: SHIMIZU HIDEO
IPC: B21C47/32
Filed: 1998-09-28
Abstract: PROBLEM TO BE SOLVED: To smoothly take up a steel plate by surely fastening its front edge to a take-up roll when the steel plate is taken up. SOLUTION: When a sliding shaft 461 is moved forward/backward via a sliding cylinder, an engaging element 463X supported by a slanting face 462a of a wedge member 462 being installed to the sliding shaft 461 moves up/down along a guide hole 463b of an engaging member 463 for pressing or separating from a linear 464 being installed at a tip end part inner peripheral face of a movable side dram 44. As a result, the movable side dram 44 rotates against a fixed side dram for forming a clearance on the roll element, into which a steel plate can be inserted, or closing the clearance. In this case, since the weight of the steel plate being taken-up by the roll element 4 acts in a radial direction of the sliding axis 461, it does not curtail the sliding cylinder, and a clearance is not formed on the take-up roll element 4 when the steel plate is taken up.

Title: Motor drive circuit
Inventor: ISHII TOSHIHIKO
IPC: H02P25/026
Filed: 1989-10-20
Abstract: PURPOSE:To reduce power loss by bringing a power operational amplifier into floating state only during the interval in which the drive waveform of the power operational amplifier for each phase of a motor drive has a magnitude corresponding to half of the source voltage. CONSTITUTION:When the potential at point A, i.e., at the output of a 120 deg. waveform synthesizing circuit, exceeds the sum of Vcc (source voltage)/2 and the base-emitter voltage VBE of a transistor(Tr) Q2, the Tr Q2 is turned ON and a Tr Q5 is also turned ON and thereby a Tr Q6 is turned OFF thus bringing an amplifier A4 into active state. Similarly, the amplifier A4 is brought into active state when the potential at point A drops below Vcc/2 by VBE of the Tr Q1. Since both Tr Q1 and Q2 are turned OFF when the potential at point A is in the range of Vcc/2+ or -VBE, Tr Q5 is turned OFF while Tr Q6 is turned ON thus bringing the amplifier A4 into floating state. By such arrangement, power loss can be reduced.

Filed: 1998-09-29
Abstract: PROBLEM TO BE SOLVED: To provide an apparatus for discharging grains for a combine harvester without wearing out a transverse auger and an auger receiver when manually overhanging and/or manually housing a grain discharging auger. SOLUTION: This apparatus for discharging grains is provided with a constitution for installing an auger receiving switch 41 capable of detecting the approach and sitting of a transverse auger 12 on an auger receiver 40 in the auger receiver 40 for housing and supporting the transverse auger 12 of a grain discharging auger 10 and performing the control so as to stop stretching operation of the transverse auger 12 when the auger receiving switch 41 is ON. When the auger receiving switch 41 arranged in the auger receiver 40 detects the approach and sitting of the transverse auger 12, the stretching operation is stopped even if the stretching operation is manually performed.  Thereby, the friction of the transverse auger 12 with a cushioning material such as rubber applied to the auger receiver 40 and wearing out of the cushioning material can completely be prevented and no excessive load is applied to an auger stretching mechanism 51, an auger stretching motor 50, etc., by friction of the transverse auger 12 with the rubber, etc., of the auger receiver 40. As a result, the wearing out and breakage of the members can be prevented.
