Title: Supercharging pressure controller for turbocharger
Inventor: UENO TAKASHI
IPC: F02D41/00
Filed: 1984-12-07
Abstract: PURPOSE:To keep off a drop in the displacement of a turbocharger after selection, by controlling a displacement variable device in a direction gradually increasing turbine displacement after being selected from control by the displacement variable device to that by an exhaust bypass valve. CONSTITUTION:A deviation between desired supercharging pressure and supercharging pressure out of a supercharging pressure detecting device 2 is calculated by a deviation operational device 9. Each controlled variable of an exhaust turbine displacement variable device 7 and an exhaust bypass valve 8 is calculated according to a running state inclusive the deviation by both first and second controlled variable operational devices 3 and 4. A running range is discriminated by a running range discriminating device 10 which discriminates the running range performing feedback control, making either of first and second controlled variable operational devices 3 and 4 perform operation of the controlled variable corresponding to the deviation selectively. After selection from control by the displacement variable device 7 to that by the exhaust bypass valve 8, the controlled variable of the displacement variable device 7 is controlled in a direction gradually increasing turbine displacement.

Title: Toner image fixing device
Inventor: INUKAI KATSUMI
IPC: G03G15/20
Filed: 1997-09-24
Abstract: PROBLEM TO BE SOLVED: To provide a toner image fixing device capable of preventing the flickering from occurring. SOLUTION: In this laser printer, a photo triac coupler 95 (PH95) is turned on when the temp. (A) falls down to ta, and this on-state continues until the temp. reaches tb. During this time, a current to a heater for fixing is passed, hence the above temp. rises. When the temp. reaches tb, the PH95 is turned off, and the off-state continues until the temp. falls down to ta. The similar control is repeated by turning-on the PH95 again, when the temp. falls down to ta. Moreover, at the time of starting to energize by turning-on the PH95 again, a discontinuous current in a pulse state as shown by (B) is passed. Then, the rush current of the heater for fixing is also parted in the pulse state, and the frequency of the voltage falls due to the rush current becomes high (C).  In accordance with the voltage fall, the intensity of illuminating light is also changes with a high frequency that hardly makes humans feel unpleasant, and the flickering can be prevented satisfactorily from occurring.

Filed: 1988-10-17
Abstract: PURPOSE:To designate not only a square picture area but an area with use of an arbitrary oblique line by using a means to designate the area under edit- processing by a vector. CONSTITUTION:Area data are transmitted from an area designating device 112 through an I/O port 114, an address, data and control bus 111 to a CPU 107. The CPU 107 operates the starting address of a vector and the gradient of the vector by the area data and writes the adding data or the subtracting data of the address every line to a RAM 106. Then, every time when a line signal is inputted to a RAM address setting device 115, the reading address of the RAM 106 is advanced. Thus, the value of the main scanning direction of the starting address of the vector is outputted from an I/O port 110. An adding device 105 adds every time when the line signal inputs the output of the RAM 106 to the starting address from the I/O port 110. An added result is supplied to a picture editing device 103 as the area data.

Abstract: PROBLEM TO BE SOLVED: To remove a streak artifact by means of an object with a high radiation absorption rate by correcting the high frequency component of a projection at a specified corresponding position on the projection of several views concerning the image of the high radiation absorbing object of a tomographic image which is re-constituted from the projection. SOLUTION: When the projection PRj1 in the view j1 is the one in a figure, for example, and a sinogram SN, that is the projection of the object is positioned at Pi on an i-axis, correction is executed concerning a prescribed range (d) including the position Pi. A corresponding position is correctly specified concerning the position Pi by utilizing the sinogram. At the time of correction, signals are made to be the ones only with the high frequency component by processing the projection PRj1 by a proper high-pass filter, a signal strength in each high frequency component belonging to the range (d) among them is obtained and subtraction is executed in the strengths which correspond in position in the projection PRi1. Thus, the high frequency components of the range (d) are cancelled.

Abstract: PURPOSE:To reduce noise generated at the time of inserting/removing a hot line and prevent the malfunction of other printed boards by connecting the ground of the printed board whose hot line is to be inserted/removed with the ground of a back board by using low-impedance conductor. CONSTITUTION:A back board 1 supports printed boards 4 and 10 by means of a signal connector 11, sends and receives a signal between the printed boards and supplies power from a power source device 3. When a hot line is removed from the printed board 4, the printed board 4 is separated from the signal connector 11. At that time, the pin of the printed board 4 repeats disconnection. A ground pin in the signal connector 11 also repeats disconnection at the same time. Therefore, for the ground of the printed board 4, the increase of the potential is observed, however, it sends only the noise whose VT product is small since the conductor 8 possessing the inductance of several 10nH or less at the direct current resistance of 10mOMEGA/cm or less is connected with a ground pad, and the malfunction of other printed boards is prevented.

Abstract: PURPOSE:To reduce the power consumption at standby by preventing some of change pump circuits from being operated at the standby by means of an operation control means. CONSTITUTION:A charge pump drive signal phi1 is oscillated in both cases of the standby and operation, but a charge pump drive signal phi2 is fixed to an H level when a phis signal is at an L level, that is, at the standby state, a fed to a charge pump circuit 3b when the phis signal is at an H level, that is, only at the operation state. Thus, when the chip is in the standby state, only the charge pump circuit 3a driven by the drive signal phi1 is operated and the power consumption at the standby state is reduced. Further, all charge pump circuits are operated at the operating state when the fluctuation of the base voltage VBE is large to compensate the fluctuation of the voltage VBE quickly thereby obtaining a stable base voltage.
