Title: Flow controller for centrifugal compressor or centrifugal blower
Inventor: NAKAGAWA KOJI
IPC: F04D27/00
Filed: 1996-05-17
Abstract: PROBLEM TO BE SOLVED: To reduce energy loss, noise and vibration in time of the small flow operation of a centrifugal compressor or centrifugal blower by a suction damper through a simple structure. SOLUTION: Two flow regulating plates 6A and 6B being rotatable in the reverse direction with each other are installed in a suction passage installed upstream in an impeller eye, while this suction passage is halved by a flow regulating plate or split plate 7 locked to this suction passage, whereby a swirl flow is produced upstream in an impeller in an intermediate opening state of these flow regulating plates 6A and 6B. With this constitution, as compared with a suction damper having one movable flow regulating plate at the upstream side of the impeller eye, noise and vibration attributable to watt consumption in time of small flow operation and an ununiformed flow are sharply reducible.

Title: Car air conditioner
Inventor: FUJIKI TSUTOMU
IPC: B60H1/00
Filed: 1991-05-28
Abstract: PURPOSE:To prevent generation of the sense of head ache by furnishing a cool wind by pass controlling means to control the degree of opening of a wind quantity controlling damper, so that it opens largely by a certain specifies amount, when the defrost mode is selected under the condition that a heater unit is in operation. CONSTITUTION:An air conditioning control unit 30 reads in the terminal voltage VB of a blower motor M1, the actual degree of opening thetaM of an air mix damper 20, and the blowout mode M, and it is judged whether the terminal voltage VB represents a wind quantity as large as generation of the sense of head ache. If yes, it is judged whether the reference value thetaM1 is exceeded by the degree of opening thetaM of the air mix damper 20 which restrains the blowout temperature, and if yes, it is followed by a judgement whether the current blowout mode is actually the defrost mode. If defrost mode, a cool wind bypass control damper 25 of a cool wind bypass 24 is opened in accordance with the external air temp. at the time so as to supply cool wind into the car cabin from the understream of a vent duct 2, and thus generation of the sense of head ache is suppressed.

Title: Production of optical fiber preform
Inventor: MIYAMOTO SUEHIRO
IPC: C03B37/014
Filed: 1988-05-23
Abstract: PURPOSE:To inexpensively obtain a high-quality optical fiber preform by depositing a porous body consisting of a glass fine particle on a rod-shaped support according to a VAD method, hanging one end of the support onto linear body, introducing their bodies into a heating furnace and dehydrating and vitrifying the porous body. CONSTITUTION:A porous body 4 consisting of glass fine particles is deposited on a rod-shaped support 3 or at the tip thereof by VAD method. Then one end of the support 3 on which the porous body 4 is deposited is hung on a linear body 1 (e.g., platinum linear body) and introduced into a heating furnace 5 and the porous body 4 is dehydrated and vitrified to provide the optical fiber preform 2. Thereby inlet 9 of the heating furnace 5 having thin diameter for only passing through the linear body 1 can be used. Consequently, positive pressure can be attained by only feeding a small amount of atmospheric gas and high-quality glass preform 2 can be obtained by suppressing entry of outer air into the furnace 5 and also expensive dopant gas used is reduced to small amount.

Title: Rotary type cell analyzer
Inventor: YAMAZAKI ISAO
IPC: G01N21/77
Filed: 1987-05-22
Abstract: PURPOSE:To reduce time required for analysis, by making a cell floating liquid, a reagent solution and a buffer flow out to the inner surface of a rotor sequentially with a nozzle turning the rotor at a high speed to eliminate pretreatment of the cell floating liquid. CONSTITUTION:When a cell floating liquid having cells floating on a floating liquid with a small specific gravity flows out through a nozzle 8 from a liquid feeder 7 turning a rotor 1 at a high speed with a rotary driver 2, the cell floating liquid 20 flows over the inner surface of the rotor 1 by centrifugal force, scattered from an upper rim of the rotor 1 and received with a liquid receptacle 9. Here, a cell the same in the size as the width of a groove on the inner surface of the rotor 1 enters thereinto and the cells 23 alone uniform in the size to a certain extent are left in the groove to be fastened by being dried. Then, when a reagent solution is sent out through the nozzle 8 from the liquid feeder 7, the reagent solution 21 flows over the inner surface of the rotor 1 to label the cells 23. Subsequently, with the flowing of a buffer 22, the reagent solution 21 retained in the groove or the like can be washed away. Thus, an optical detector 4 is operated being controlled with a controller 6 thereby detecting the nature of the cells 23.

Title: Digital-analog converting method
Inventor: YONEZAWA YOSHIAKI
IPC: H03M1/82
Filed: 1982-07-15
Abstract: PURPOSE:To obtain a D/A converting circuit which can work at a high speed with a low distortion factor, by dividing plural integration circuits connected to each other into groups, giving a converting operation to each group and storing the results of integrations of those groups to an integration circuit of the final stage. CONSTITUTION:A reference potential source 14 corresponding to the lowest bit of a digital signal is integrated by an integration circuit I1 by the number of reference clock pulses which is equal to the data value of a group G1. Thus the electric quantity equivalent to the data of the G1 is obtained. Then a switch means 12 of the first stage is closed for a time decided by a time generating circuit 16, and the electric quantity having the waiting equivalent to the lowest bit of the G2 is generated at the output of the circuit I1. This electric quantity is integrated by an integration circuit I2 for a period during which a counter 17 counts the clock pulses of a number equivalent to the data value of the G2. Then the electric quantity corresponding to the data value of the G2 is delivered. Thereafter the same operations are carried out up to a group GN. As a result, an n-bit digital signal is converted into an analog signal.

Title: Controller for system equipped with prime mover and hydraulic pump
Inventor: TANAKA YASUO
IPC: F02D41/14
Filed: 1984-06-18
Abstract: PURPOSE:To improve the operation feeling by smoothly increasing the revolution speed of a prime mover and the discharge amount of a pump in accordance with the increase of the operation signal when an operating lever for the instruction for tilting the pump which is used for adjusting the discharge amount of a hydraulic pump is sharply operated to increase the speed of an actuator. CONSTITUTION:When a lever 12 for the instruction for tilting a pump which operates onto a pump regulator 14 and a throttle lever 5 are sharply operated at a same time, an aimed revolution-speed signal N1 increases, and the deviation signal DELTAN from the output revolution-speed signal N of a primar mover 1 by a revolution-speed detector 6 increases. Then, a relatively small integration value delta1 is input into an integrator 14 from an aimed revolution-speed integration-value-function generator 13, and the second aimed revolution-speed signal N2 through the sequential addition of the integratin value delta1 is outputted into a min. value selecting device 15. Said selecting device 15 selects the min. value between N1 and N2, and the sharp increase of the aimed revolution speed signal No is suppressed. Therefore, the sharp increase of te revolution-speed deviation signal DELTAN is suppressed, and the discharge amount of a hydraulic pump 3 is smoothly increased in accordance with the operation signal Xo of the operating lever 12.
