Title: Freighter for oceanic voyage
Inventor: SHIBATA KIYOSHI
IPC: B63B1/04
Filed: 1984-05-14
Abstract: PURPOSE:To provide an ocean-voyaging hull greatly reduced in friction resistance and fitted with a uniaxially spiral propeller, by setting the length of the hull at 100m or more, the ratio of the length to its width at 3.5-5 and its block coefficient at 0.7-0.8. CONSTITUTION:The length L of a hull, the ratio L/B of the length to its width B and its block coefficient Cb are set at 100m or more, 3.5-5 and 0.7-0.8, respectively. The hull is fitted with a uniaxially spiral propeller. Since the length of the hull is made small, the wetted surface area of the hull is decreased so that the friction resistance thereto is reduced. Since the ratio L/B is set at 3.5- 5, the flow of water does not separate from the surface of the hull, so that its wetted surface area can be made relatively small to reduce the friction resistance. Since the uniaxially spiral propeller is provided, higher propelling performance is attained.

Title: Torque variation generator
Inventor: KADOMATSU KOJI
IPC: G01M15/00
Filed: 1990-04-13
Abstract: PURPOSE:To correctly perform measurement and evaluation by fixing a hydraulic torsion exciter, whose output shaft is coupled directly with a flywheel, to a cylinder block, and applying an engine with excitation torque through the reaction wherein the hydraulic torsion exciter excites the flywheel. CONSTITUTION:The excitation torque is applied from a flange part 25 provided at one end of a shaft as an output shaft to the flywheel 4 which is coupled directly therewith to excite the flywheel 4 directly. When the flywheel 4 is thus excited, the engine 1 is applied with the excitation torque as the reaction for exciting the flywheel 4 since the hydraulic torsion exciter 2 is fixed to the engine 1. Then roll moment generated by the explosive pressure of the engine 1 can be reproduced with the excitation torque. The actual roll moment force is varied in torque at the frequency corresponding to the speed of revolution of the engine 1, but the torque variation can be generated within a range of 1 - 1,000Hz according to the control of a servo value 11 and is therefore easily reproduced even at a low frequency lower than about 209Hz corresponding to idling operation.

IPC: G01S7/285
Filed: 1995-04-21
Abstract: PURPOSE: To enable inexpensive and high-accuracy setting against the variation of a reception system amplitude by providing an adder, which can set a variable attenuator, at a low-order bit between the variable attenuator and a control circuit. CONSTITUTION: The microwave module is provided with a variable attenuator 3 to be used for reception waiting and to be set by the control circuit and a phase shifter for controlling a phase for each module, and an adder 3b which can set the variable attenuator 3 is provided at the low-order bit between the variable attenuator 3 and the control circuit. This microwave module also uses the variable attenuator 3 of reception waiting for controlling the variation of gains between the modules. Therefore, the module can always be used in a constant stable state without controlling the bias of a low-noise amplifier. Besides, the reception system gain variation between modules can extremely easily be decreased without additionally controlling the attenuator.

Title: Transporting method for raw material into blast furnace top by belt conveyor
Inventor: SUZUKI SHIYOUICHI
IPC: B65G65/32
Filed: 1981-06-23
Abstract: PURPOSE:To improve the raw material charging capacity in a blast furnace by adjusting the space between the raw materials to be conveyed by a belt conveyor in the case of storing the same raw materials continuously and in the case of charging separate materials into furnace top hoppers. CONSTITUTION:In the stage of deliverying charging raw materials from hoppers 1A-1D on the ground onto a belt conveyor 2, it is assumed that, for example, the charge partterns C, C , C , O, O  are incorporated. The first C, C are stored continuously into the same furnace top hopper 4B and therefore the space l1 between the coke C1 to be conveyed first and the coke C2 to be conveyed in succession to the coke C1 on the conveyor 2 is substantially unnecessary. However, the coke C3 to be conveyed next is charged independently of the portion by one time into the hopper 4A and therefore it is necessary to provide a space l2 between the coke C3 and the coke C2. In the stage of delivering ore O, a space between the same and the coke C3 is required but there is no need for a  transport spacing between the ores O and O.

Abstract: PURPOSE: To manufacture basic pentacalcium triphosphate of high quality in one process by removing org. matter from bones of a mammal, converting the bones into granules of a specified grain size, and calcining them in a fluidized carbonization furnace.  
     CONSTITUTION: Bones of a mammel such as a cow or a pig as starting material are treated with steam or high frequency to remove fat, gelatin, etc., and they are converted into 4W8mm granules to facilitate fluidization and enable uniform calcination. The granules are continuously charged into fluidized carbonization furnace of 900W1,100°C little by little and carbonized while being fluidized and heated. Since the bones are in the form of granules, the penetration of CO is carried out sufficiently and they are heated uniformly to remove carbon, sulfide and other impurities thoroughly and uniformly. Calcination is completed in about 25min after the charge. The yield of basic pentacalcium triphosphate reaches 50W60%, and this product has a well-balanced wt. ratio of calcium to phosphoric acid (about 1:1) and high purity.
