Title: Method and device for correcting dark state output of image sensor
Inventor: YAMAZAWA AKIRA
IPC: H04N5/378
Filed: 1993-10-15
Abstract: PURPOSE:To provide the method for correcting a dark state output of an image sensor reducing dispersion in a dark state output in order to prevent deterioration in the image quality due to the dispersion in the dark state output of the image sensor. CONSTITUTION:A counter circuit 41 whose count corresponds to the bit number for dark state output correction is counted synchronously with a bit output clock. a digital output of the counter circuit 41 is D/A-converted and a resulting analog signal is fed to a differential amplifier 44. The differential amplifier 44 subtracts an analog signal obtained by D/A-converting a digital output of the counter circuit 41 from a picture read output (analog signal) of a sensor 45 corresponding to each bit to obtain a picture read output (analog signal) of a sensor 45 to be corrected. Thus, in the image sensor where its dark output level is almost uniformly changed corresponding to a time series and a picture element string, a dark state output is corrected without loss of digital resolution and without use of expensive circuit configuration.

Abstract: PROBLEM TO BE SOLVED: To reduce a memory space and a memory capacity used for an address conversion table without placing a limit on the use of an address field by stepwise reducing the address space up to an output destination address space specified by the total number of output destinations. SOLUTION: A lowest level S1 of an address converter 10 consists of M-sets of address conversion tables Table(1)11-Table(M) 14. The address conversion tables of levels S1, S2 adopt a 2:1 connection form where an output OUT1 (X) of the two conversion tables of the level S1 connects with an input of one table of the level S2. Then a root of the hierarchical tree structure, that is, the highest level SZ consists of a sole table memory TableZ(1)19. The table memory 19 applies address conversion to data outputted from two table memories TableZ-1(1)17 and TableZ-1(2)18 included in the 2nd highest level SZ-1 and provides an output of the conversion result.

Title: Braking force controller
Inventor: YAMAGUCHI TOUMA
IPC: H02P7/00
Filed: 1997-09-08
Abstract: PROBLEM TO BE SOLVED: To provide a braking force controller which can secure braking force properly even at fault of a controller or a motor driver. SOLUTION: An normally open contact part 8a by the excitation of an exciting coil 8b and a converting circuit 9 are interposed in series between a stepping force sensor 6 and each motor driver 4. The converting circuit 9 converts the stepping force detected by the stepping force sensor 6 into command signals (torque command voltages VFL, VFR, VRL, and VRR for a left fore wheel, a right wheel, a left wheel, and a right abt wheel). The watch dog circuit of a controller 7 stops the current application to the exciting coil 8b in case that the controller 7 goes wrong.  In case that the controller 7 has gone wrong, the contact 8a is closed, and the converting circuit 9 converts the detection result of the stepping force sensor 6 into a command signal, and outputs it to the motor driver 4 so the braking force can be secured by driving the motor 2 even at fault of the controller 7, and the reliability on a drive brake can be improved in its turn.

Filed: 1998-08-28
Abstract: PROBLEM TO BE SOLVED: To prevent the cleaning defect of a belt running body with lapse of time in an image forming device at a low cost with the reduced space. SOLUTION: As for this device, when cracks are developed with time on a surface applied coating on a transfer belt 17a, toner being entered therein, becomes to be uneasily removable by the cleaning blade 17e.

Title: Flywheel assembly for automobile
Inventor: KAJITANI KOJI
IPC: F16F15/134
Filed: 1995-10-06
Abstract: PURPOSE: To reduce a noise when a vehicle is operated by rotatively supporting a second flywheel on a first flywheel supported by a flexible plate, and arranging a damper mechanism between the first and second flywheels. CONSTITUTION: A second flywheel 6 is rotatively supported on a first flywheel 1 fixed to the crankshaft 25 of an engine through a gearing 5, and a liquid viscous damper mechanism 60 is arranged between the first and second flywheels l, 6. Engine side rotational force is transmitted from the first flywheel l to the second fly-wheel 6 through the damper mechanism 60, and transmitted from the second flywheel 6 to a transmission side. Twist vibration during a power transmitting period is absorbed by the damper mechanism 60. When bending vibration is generated on an engine side during the power transmitting period, it is transmitted to a flexible plate 70 so as to be absorbed. As a result, the bending vibration on the engine side can be prevented from being transmitted to the transmission side so that a noise when a vehicle is operated can be reduced.
