Title: Forced operating method of direct-coupled unit
Inventor: TAKADA TSUTOMU
IPC: E03B11/16
Filed: 1993-04-15
Abstract: PURPOSE:To replace water in a pump with fresh water by a method wherein a pressure tank type feed water pump for feeding water to a building or the like from a feed water main pipe is forcibly operated even if water is not used, when the number of operations of the pump per day is less than a set value. CONSTITUTION:Water is fed to a building 8 such as an apartment house by a pump 4 with a pressure tank 7 from a feed water main pipe L through a suction pipe L1 with a check valve 1. In this case, when a set value of delivery pressure is always lower than suction side pressure, water is fed to the building 8 without operating the pump 4. And when the number of operations per day of the pump 4 becomes less than a set number, the pump 4 is forcibly operated regardless of whether or not there is a flow of water in a lifting pipe L2. As a result, the water remaining in the pump 4 can be replaced with fresh water.

Title: Detecting method for velocity of synchronous motor
Inventor: KURAKAKE MITSUO
IPC: H02P29/00
Filed: 1981-06-09
Abstract: PURPOSE:To detect precisely an actual velocity of a synchronous motor by conducting an operation for preestimation of a present actual velocity according to the characteristic formula of the synchronous motor by using a past current instruction value and a past detection speed every time when an interrupt signal  of a constant cycle is generated. CONSTITUTION:FF402 is set by a pulse Pa generated from a pulse generator 102 fitted to the shaft of a synchronous motor, while being reset by a velocity operation end signal OPEN generated from a processing unit 113. An interrupt pulse generating circuit 403 generates a velocity operation interrupt pulse ITP of a constant cycle. When the pulse ITP is generated at a time, the unit 113 senses the state of setting of FF402. When FF402 is not set, the unit 113 executes an operation of a prescribed formula by using a past detection speed V(K-1) and a past current instruction IS(K-2) which are stored in a data memory 113c, and thereby preestimates the velocity of rotation V(K). Then, by taking the velocity V(K) as an actual velocity, the difference between the same and an instructed velocity VD is determined, and based thereon, a primary-current instruction is delivered to a synchronous motor 101.

Title: Brake controller for electric automobile
Inventor: KUSAKA YASUSHI
IPC: B60L7/24
Filed: 1992-04-09
Abstract: PURPOSE:To improve brake feeling by generating only mechanical brake power if brake operation is started during speed change operation whereas generating regenerative power gradually if brake operation endures at a point of time when speed change operation ends. CONSTITUTION:An EV controller 50 operates a torque command based on a stepping amount of accelerator pedal, a brake amount, and the like and an operation result is delivered, as a torque command value, to an inverter controller 52. The inverter controller 52 produces a current command in response to the command value and controls output torque from a motor 10 through control of a power converter 14. In other words, if brake operation is started during speed change interval, only mechanical brake power is produced and the number of revolution of the drive motor 10 is controlled thus suppressing speed change impact. Furthermore, regenerative brake power is controlled to be generated gradually if brake operation endures at a point of time when speed change operation ends. According to the constitution, abrupt deceleration does not take place at the end of speed change operation resulting in improvement of brake feeling.

CONSTITUTION:Besides the normal shift detecting means 48 which detects the normal shift of the heat-resistant endless belt 23, the abnormal shift detecting means 1 which detects the abnormal shift of the belt 23 is provided. Namely, when an image forming device containing a fixing device is installed at an extremely uneven place and the heat-resistant endless belt 23 keeps unidirectionally shifting, it is judged to be jammed by a microcomputer based on a signal from a photointerrupter 6 through an abnormal shift detecting lever 1, a pinion 2, and a rack 3, etc., and the action of a main body is stopped. Consequently, since a main body motor is stopped, the heat-resistant endless belt 23 is not completely shifted and is stopped, and thereby occurring no rupture.

Abstract: PURPOSE: To prepare the titled compound useful as bifidus factor, in high yield, by reacting an N-substituted aziridine with a thiosulfate in the presence of a cation exchange material, removing the protective group if necessary, and reacting with pantolactone.  
     CONSTITUTION: The compound of formulaI(R 1  and R 2  are H, amino-protecting group or pantoyl) is made to react with a thiosulfate in the presence of a cation exchange material (i.e. a free-type strongly acidic cation exchange resin) to obtain the alletheine-S-sulfonic acid derivative of formula II (M is H, alkali metal,  etc.). The objective compound of formula III can be prepared by reacting the  compound of formula II directly when the R 1  and R 2  are H and pantoyl group,  or after removing the R 1  or R 2  when it is amino-protecting group, with pantolactone. The presence of the cation ex change material suppresses the by-production of the hardly separable inorganic salts in the production of the compound of  formula II, and facilitates the move to the next step.

Title: Production of microcapsule
Inventor: OKIMOTO SATOYUKI
IPC: B41M5/165
Filed: 1978-07-22
Abstract: PURPOSE:To produce stable polynuclear capsules of specified grain size in high grain size precision, by adequately balancing the mutually sticking force of coacervates deposited around micro-drops of oily substance containing polyisocyanate, by using separating force due to agitated flow. CONSTITUTION:An oily substance (e.g. kerosene) in which are dissolved or dispersed polyisocyanate (e.g. m-phenylenediisocyanate) and organic coloring agent (e.g. crystal violet lactone) is emulsified in an aqueous solution (primary sol) of hydrophilic colloidal substance. Next is mixed an aqueous solution (secondary sol) of hydrophilic colloidal substance having the reverse electric charge of the primary sol. This mixture is emulsified while applying high speed agitation flow by means of homogenizer or the like, and by adding water of adjusting pH, the so-called coacervation which separates the colloid into concentrated phase and dilute phase is produced. While the temperature of this system declines, the separation of agitation flow controlling the adhesive force of single-nuclear capsules within the range to produce aggregates of average grain size of 3 to 20mu is applied, and desired polynuclear capsules are produced.

IPC: F04B23/04
Filed: 1989-04-11
Abstract: PURPOSE:To simplify the structure of a fluid conveyor by providing a hydraulically operating valve moving between inflow ports in a pipe having two inflow ports and one outflow port, and opening and closing the two inflow ports by a single operating valve. CONSTITUTION:The pipe 20 of a hydraulically operating valve 14 is constructed in a T-shaped pipe in such a way that both end opening portions are inflow ports 17, 18 of fluid from each of pumps 12, 13 and an outflow port 16 is formed at the side central portion thereof. The inner diameters of the openings of the inflow ports 17, 18 at both ends of the pipe 20 are formed smaller than the inner diameter of the pipe 20. A moving body 19 is fitted in the pipe 20. The moving body 19 includes a column portion having an outer diameter fitted to the inside of the pipe and portions of both bottoms formed in conical shapes, and its length is set shorter than the length between the outflow port 16 and each of inflow ports 17, 18. Due to this construction, when one pump 12 is operated, fluid is guided to flow in from the inflow port 17 to push the moving body 19, so that the non-operation side inflow port 18 is closed thereby and the fluid flows out from the outflow port 16. Consequently, the two pumps 12, 13 can be alternatively operated by the single operating valve.
