Title: Carrying speed controller for body to be scanned
Inventor: SUGANUMA ATSUSHI
IPC: H04N1/04
Filed: 1987-09-21
Abstract: PURPOSE:To make the speed carried in the subscanning direction constant with respect to a resonance frequency independently of the change in ambient temperature or the like by detecting the change in the resonance frequency of a resonance optical deflector so as to apply feedback control to a motor carrying the body to be scanned in the subscanning direction. CONSTITUTION:The turning speed, that is, the resonance frequency of a deflection mirror 34 is changed by the fluctuation of ambient temperature in a resonance type optical deflector 32. The drive speed of a pulse motor 35 is controlled by controlling the drive speed of the drum 38 such that the change in the speed signal Sv from the resonance optical deflector 32 with respect to the resonance frequency is controlled to flow down the drive speed of the drum 38 when the resonance frequency is lower and the change is controlled to increase the drive speed of the drum 38 when the resonance frequency gets higher.

Title: Sliding vane compressor
Inventor: SUZUKI SHIGERU
IPC: F04C18/344
Filed: 1983-12-19
Abstract: PURPOSE:To prevent a vane from chattering so as to enable the compression of fluid at starting a compressor to be effectively avoided, by providing a resistance generating means which applies resistance to a flow of fluid in oil flow paths communicating with an oil separator chamber and some of the vane grooves. CONSTITUTION:Holes 76-79 serving as some of the pressure guiding passages are respectively drilled toward the axial center of a rotor 36 in bottom surfaces of vane grooves 68-71, causing the pressure in an oil separator chamber to act on rear end surfaces of vanes 72-75. Of the holes 76-79, the hole 76 and the hole 78, oppositely drilled to said hole 76, form a throttling passage having a flow path in sectional area so as to generate resistance in a flow of oil or the like supplied from an oil reservoir. Accordingly, even if the compression of fluid is caused in a working chamber of a compressor when it is started, abnormal pressure can be relieved to the neighboring working chamber interposing the vane with weak pressing force.

Abstract: PURPOSE:To preven the variation of powdery ore level in a downtake tube and to improve the working efficiency of a fluidized reduction furnace by directly fitting a supplying device for powdery iron ore to the downtake tube in the circulating fluidized reduction furnace composed of an uptake cylinder and the downtake tube for the powdery iron ore. CONSTITUTION:At the time of pre-reducing the powdery iron ore in the circulating fluidized bed type pre-reduction furnace 10, the powdery iron ore 4 is charged from a lower charging hole 3 in the uptake cylinder 1 and pre-reduced in the solid phase with reducing gas 5 supplied from the lower part in the pre-reduction furnace 10, and the powdery ore separated from gas with a cyclone 6 is descended in the downtake tube 2. The reduced ore is discharged from an outlet 7 and unreducing powdery ore is again returned back in the uptake cylinder 1 and pre-reduced. In this case, when quantity of the circulating powdery ore in the downtake 2 becomes little, the reducing gas 5 blown into the uptake cylinder 1 is caused to flow into the downtake tube 2, and collecting efficiency of the cyclone 6 is reduced and the fluidized bed in the uptake cylinder 1 becomes unstable. Hereby, this condition is detected with a level meter 11, and the powdery ore in a hopper 13 is supplied into the downstream tube 2 from a powdery ore supplying device 9 arranged in the downtake tube 2, and blowby of the reducing gas 5 to the downtake tube 2 is prevented and the operational condition is stabilized.

IPC: G11C11/41
Filed: 1990-09-10
Abstract: PURPOSE:To output a detected pulse at high speed and with stable response time by constituting a signal synthesizing means with bipolar transistors connected in parallel which are driven in accordance with each detected signal. CONSTITUTION:The changes of each logical level of plural input signals IN1-INn are detected by signal detection means 100-1-100n to output each detected signal to the signal synthesizing means 200. The plural detected signals are logically synthesized by the signal synthesizing means 200, i.e., when any of the detected signals is outputted, the operation is made so as to output a signal of 'H' level for example. This signal synthesizing means 200 is formed in such a manner that the bipolar transistors in the quantity corresponded to that of the input signals IN1-INn are connected in parallel, and the ON/OFF operation is performed with supplying each detected signal to the bases. By this procedure, the delay of output signal to the level change of input signals IN1-IN4 is shortened, and the variance of delay time for the output signal according to the quantity of changes in input signals IN1-IN4 is restrained.
