IPC: F04D29/68
Filed: 1984-06-27
Abstract: PURPOSE:To prevent surging by allowing the slit parts of the both casings to be engaged each other and shifting one slide casing in the axial direction and opening the slits on the other casing, in the range of wind amount where surging is generated. CONSTITUTION:A number of slits cut in a short range on a body casing 3 and a slide casing 4 are engaged each other to form a slit 7. When a blower or a compressor generates a wind amount in the range for generating surging, a slide casing 4 is shifted in the axial direction in a space 6a, namely leftward on the figure by the operation of a slide-casing 4 shifting means equipped with an actuator 10, and the slit 7 on the inner periphery of the body casing 3 in the inlet part of a vane wheel 1 is opened, and generation of surging is prevented, and the operation range is widened to a small flow-rate side. In other words, within a range where the slit 7 is closed, high-efficiency operation is permitted, and when the operation on the small flow-rate side is necessary, the slit 7 is opened, and the operation control range is widened.

Title: Regeneration of resin for selective adsorption of boron
Inventor: YOSHIKAWA TOMOHIKO
IPC: C01B35/10
Filed: 1983-07-19
Abstract: PURPOSE:To enable stable adsorption treatment of boron by allowing resin for selective adsorption of boron which has been converted to free amine form by the regeneration with alkali soln. to contact with soln. of neutral salt, and converting the free amine part of the resin having function for decomposing neutral salt to a salt loaded form. CONSTITUTION:Mother body of resin obtd. by haloalkylating styrenic copolymer is aminated with an amine expressed by the formula {wherein (n) is an integer 1-6; R is -CH2-[CH(OH)]m-CH2OH or alkyl group; (m) is zero or an integer <=6} to obtain resin for selective adsorption for boron; boron in the soln. is adsorbed with the abovedescribed resin. In this process, the resin is regenerated to the free amine form using alkali soln. and the free amine from resin is allowed to contact with soln. of neutral salt to convert the free amine form part of the resin to the form loaded with the neutral salt, which is used for the adsorption treatment. As the result, blocking of hardness component or heavy metal component contained in the soln. due to formation of hydroxides, or elevation of pH of the treated liquid is prevented enabling stable operation of adsorption.

Title: Engine speed controller and heat pump system of internal combustion engine
Inventor: TAUCHI TAKUYA
IPC: F02D41/14
Filed: 1996-04-27
Abstract: PROBLEM TO BE SOLVED: To control an engine so as to restrain the deviation amount of the actual engine speed from the set engine speed to the minimum extent while restraining racing caused by overshoot. SOLUTION: An engine is controlled by PID control so that the actual engine speed N2 may coincide with the set engine speed N1. When the actual engine speed N2 is dropped and exceeds a threshold value A caused by variations in the fuel supplying amount, correction for adding an additional value Sa to a command value Sb of PID control is performed to accelerate the restoring gradient of the actual engine speed N2. In a wave form of one cycle (an additional cycle) drawn by the additional value Sa, the gradient in rising to the maximum value is steep, the gradient in lowering from the maximum value is gentle, and they are held in the maximum value for the specified time. Values found from the preliminary test in which variations in the engine speed is minimized are adopted for the threshold value A, the cycle of the additional cycle, and the maximum value, and correction of the command value Sb is performed plural times until the actual engine speed N2 is restored to the threshold value A.

Abstract: PROBLEM TO BE SOLVED: To suppress the leakage current flowing from the winding to the stator to a brushless motor at switching of PWM(pulse width modulation) between upper and lower arms. SOLUTION: A pulse width modulation circuit 39 generates a PWM signal Sm, by comparing a voltage command signal Ss with a triangular wave carrier signal Sc1 generated from a triangular wave generating circuit 38.

Title: Display label and fitting method for display label
Inventor: KIMIJIMA TAKAO
IPC: B60C13/00
Filed: 1997-05-22
Abstract: PROBLEM TO BE SOLVED: To prevent the label from peeling even if a displayed body deforms. SOLUTION: The display label 30 fitted to the surface of the side wall part of a tire consists of an annular buffer layer 34 formed of an endless rubber belt, etc. If the tire deforms and the side wall part expands, a base material layer expands similarly. The expansion causes the buffer layer 34 itself to expands and shrink and then the expansion of the buffer layer 34 is dispersed by the expansion and shrinkage. Consequently, the expansion of the side wall part is absorbed by the expansivity and not applied to a label layer 32 as it is.
