Title: Image forming device and process cartridge
Inventor: KATO JUNICHI
IPC: G03G21/16
Filed: 1993-11-25
Abstract: PURPOSE:To provide an image forming device capable of preventing the increase of torque, abnormal noise, and heat generation on a developing sleeve or a magnet roller from occurring even if the case the magnet roller is warped. CONSTITUTION:A line connecting the center of a photoreceptor 2 with the center of a developing sleeve 8 is made horizontal, the angle of pressing force P1 exerted on the developing sleeve 8 is theta1=90 deg., and a warping direction is a direction V1. A position where the developing blade 9 abuts on the developing sleeve 8 is in a direction of theta2=160 deg., abutting pressure works in a direction shown by an arrow P2 and the warping direction is a direction V2. Thus, the warping Vs being the vector sum of the warping V1 and the warping V2 is generated, and its direction is thetas=14 deg. and faces downward. As a result, the developing sleeve 8 is warped downward, so that a space between the inside surface of the developing sleeve 8 and the external surface of the magnet roller 18 can be sufficiently secured even when the magnet roller 18 is bent in a gravity direction by a dead weight.

Title: Semiconductor input circuit
Inventor: SHIDEI TSUNAAKI
IPC: H03K19/0185
Filed: 1993-12-17
Abstract: PURPOSE:To provide a semiconductor input circuit which supplies appropriate threshold potential to an input signal of TTL level and with short delay time of an output signal. CONSTITUTION:When the input signal is set in an 'H' level that is the TTL level, both a PMOS 11 and a NMOS 12 are set in an energized state. In such an energized state, the level of an output signal is decided by a resistance ratio when the PMOS 11 and NMOS 12 are energized, and the threshold potential of the input circuit is also decided by the resistance ratio when the PMOS 11 and NMOS 12 are energizeed. When the input signal changes from 'H' to 'L', PMOSs 21, 22 are set in the energized state until the potential of an output terminal Out2 exceeds the threshold potential of an inverter 23, and a resistance value between power supply potential Vd and the output terminal Out2 is decreased. Therefore, the rise delay time of the output signal can be shortened.

Abstract: PURPOSE:To achieve that a cooling air current flows sufficiently by a method wherein an air-current control plate is installed on the side face of a multichip module so as to be parallel to the flow direction of the cooling air current. CONSTITUTION:In a structure in which air-current control plates 2 are arranged on both sides of a multichip module 3, the air-current control plates 2 are arranged on side faces of the multichip module 3 in positions parallel to the flow direction of a cooling air current 1.

Title: Magnetic recording and reproducing device
Inventor: HAKOMIYA KEIJI
IPC: H04N9/80
Filed: 1988-12-20
Abstract: PURPOSE:To play back a PAL system VHS tape and to reproduce a color on an NTSC system TV in a normal hue by adding a system conversion circuit. CONSTITUTION:A signal, in which the VTR of a PAL system VHS is recorded, is reproduced in a PAL mode, an obtained carrier chrominance signal is kept as it is in one horizontal synchronizing period of a +135 deg. burst phase and balance-modulated with a carrier having the double frequency of the frequency of a reference oscillator 7, in one horizontal synchronizing period of a -135 deg. burst phase, and the difference component is taken out. As the result, a carrier chrominance signal having a phase obtained by inverting a V axis is obtained, and a chrominance sub carrier including burst, in which the V axis is never inverted in every one horizontal synchronizing period, is obtained. Since only the burst exists in a +135 deg. phase, an NTSC system chrominance signal can be obtained by advancing the phase for +45 deg. in a phase shifter 14. Even when the signal is connected to the NTSC signal TV set, the color can be reproduced in the normal hue.

Title: Image display device
Inventor: CHIBA JUNICHI
IPC: G09F13/32
Filed: 1994-12-22
Abstract: PURPOSE: To display one-dimensional information as two-dimensional information on an image receiving tube by oscillating a lens or an LED array in the direction orthogonal to the arrangement direction of LED elements. CONSTITUTION: This image display device is constituted of an LED array 1 formed of a plurality of LED elements arranged one-dimensionally, a lens 3 for image formation of light emitted from each LED element on an image receiving tube, and a lens driving mechanism. The lens 3 is oscillated by means of the lens driving mechanism in the direction X orthogonal to the arrangement direction Z of the LED elements in the LED array 1. A light beam from the LED array 1 magnified in association with the oscillation of the lens 3 is expanded in the oscillation X of the lens 3 through an after image and displayed as a flat plane image. Consequently, by sequentially displaying image information one-dimensionally at an appropriate timing on the LED array 1 and oscillating the lens 3 interlocking with this display, two-dimensional image information is displayed on the image receiving screen.

Filed: 1991-11-08
Abstract: PURPOSE:To automatically group output signals which are mutually independent and fault diagnosis possible from the view point of the ladder program of a programable logic controller(PLC). CONSTITUTION:A monitoring object output coil is selected (step 101). The list of input/output contacts (adding an internal auxiliary contact) which are referred by the respective output coils in the ladder program is generated (step 104).

The coupling degree calculation is processed as to all the selected output coils. The coupling degree is referred and, then, grouping is executed so that the mutually related output coils belong to the same group (step 107).

Filed: 1987-12-17
Abstract: PURPOSE:To absorb and return energy surely by inserting an inductance means into the current path of a main circuit and by charging a capacitor once with the stored energy of said means at the time of turning OFF a switching transistor. CONSTITUTION:A switching regulator is connected from a DC power 1 to a load 24 via inductor 20, the primary winding 5a of a current transformer 5, a transistor(Tr) 7 and an inductor 10, and turns ON and OFF said Tr 7 by a base driving circuit 19.

Abstract: PURPOSE:To reduce the data storage capacity of a control condition setting part and to easily change control procedure by providing the machine control device with a control procedure setting part for setting up the control procedure, inputting an execution start signal and outputting control procedure data. CONSTITUTION:A control part 1 outputs an execution start signal (a) to the control procedure setting part 2 and receives an execution end signal (f) from an execution part 6 to successively outputs the signal (a). The setting part 2 outputs control procedure data (b) to a decoding part 3 at the time of inputting the signal (a) and the decoding part 3 decodes the data (b) by a decoder and outputs a control condition selecting signal (c) to the control condition setting part 4. The setting part 4 previously setting up control conditions in its internal control memory or the like outputs the control condition data (d) selected by the signal (c) to a formation part 5. The formation part 5 forms and outputs execution data (e) to the execution part 6, which inputs the data (e), executes the processing of the data (e), i.e. the control of an external machine, and sends the signal (f) to the control part 1. Consequently, the data storage capacity of the setting part 4 can be contracted and the execution procedure can easily be changed.
