Title: Thrust bearing device
Inventor: OONISHI AKIRA
IPC: F16C17/06
Filed: 1980-07-02
Abstract: PURPOSE: To enhance the free-to-oscillate characteristic of a spring construction by inserting the support into the hole eccentrically outerward and by holding the spring so that the support and the hole are in contact with each other.  
     CONSTITUTION: The diameter d 1  of a support 10 and the diameter d 2  of a hole in a spring 5 shall be in contact with each other by a line or a plane, and the misalignment of these two shall be eliminated. The contact is obtained by setting the circular section of the support 10 eccentric with respect to the circular section of the support inserting hole of the spring 5, where displacement δ of the spring 5 caused by its own weight shall be set to zero and, also, misalignment δ of the load center in the spring 5 with respect to the load center in an adjustment bolt 6 shall be set to zero. During operation, the support 10 is so controlled that the support inserting hole in the spring 5 will not be in contact, and thus a gap is produced by deflection of the spring 5, so that the free-to-oscillate characteristic of the spring is not spoiled.

Abstract: PURPOSE:To attain the miniaturization and light weight of a device and to perform the simultaneous reading of plural originals by arranging plural image reading units in the periphery of a single light source. CONSTITUTION:Light irradiating from a light source 1 transmits the original 2, and is limited to linear light(direction in parallel with a CCD sensor 5) by a slit 3, and magnification is adjusted by a lens 4, and it is introduced to a CCD sensor 5. The CCD sensor 5 converts the light from a film 2 to an electrical signal, and the reading of the CCD sensor is repeated sequentially as moving the film 2 in a direction perpendicular(subscan direction) to that of a sheet. Simultaneously, the reading of a film 6 is performed by a CCD sensor 9. Thus, by performing the reading of the plural originals simultaneously, productivity can be improved, and the light source 1 can be made into common use, therefore, the device can be miniaturized as a whole.

Filed: 1978-07-21
Abstract: PURPOSE: To permit a continuous speed control without occurence of any slackening in a line, by setting a minimum bias torque greater than the mechanical loss of a picking-up pinch roller.  
     CONSTITUTION: A differential amplifier 16 supplies a deviation signal between speed command signal 14 and a speed feedback signal 15 to phase shift ignition circuit 17 as a phase control command signal. A torque-bias-circuit 20 generates, a predetermined output when the armature current, which is detected by a resistor 18, corresponding to a torque occurred on a DC-motor 4, may be not more than a current value set by a minimum torque setting signal 19 and generates no output when over the setting current value. Therefore, when the armature current may be not more than the setting current value because of the slackening occurred in the line, the DC-motor 4 is accelerated to correct the slackening in the line.

IPC: C02F1/40
Filed: 1998-04-02
Abstract: PROBLEM TO BE SOLVED: To usually and stably suck scum by gathering the flow-in scum with a gathering plate toward a suction pipe. SOLUTION: The gathering plate 2 having an inverse triangular plane shape from the view point of the suction pipe 1 is provided to slowly gather the flowing-in scum continually toward the suction pipe 1.

As a result, the suction pipe 1 is inclined to an opposite side against the flowing side of the scum to reduce the resistance in the scum suction. Also, an inverse triangular guide plate 1b having smaller length than the gathering plate 2 is provided at the lower end surface of the suction part. Thus the scum is suppressed in sedimentation and safely sucked.

Title: Frictional material
Inventor: MISAWA NORIO
IPC: C08J5/14
Filed: 1994-04-27
Abstract: PURPOSE:To reduce the crack resistance without affecting other characteristics of a frictional material and reduce the occurrence of creaks. CONSTITUTION:This frictional material has a two-layer structure and is formed from a frictional material layer on the frictional surface side containing a fibrous substrate, a resin binder, cashew dust and other fillers and a frictional material layer on the back board side having the same composition as that of the frictional material layer on the frictional surface side except that a resin having a high heat-resistant strength is used as the binder and at least a part of the cashew dust is replaced with rubber powder. The thickness of the frictional material layer on the back board side is 5-30% based on the whole frictional material to form a regional part close to the back board easily causing cracks. Since the resin having the high heat-resistant strength is used as the binder in the frictional material layer on the back board side, the crack resistance is improved. For example, a xylylene-modified phenol resin can be used as the binder. The rubber powder in the frictional material layer on the back board side is capable of reducing the occurrence of creaks by the vibration damping actions thereof.

Filed: 1980-07-04
Abstract: PURPOSE:To detect the measured length of the sample of the electrophoresis pattern by calculating the sampling number of the electrophoresis pattern from its start to the end and that of the first change point to the end from the end by a micro-computer. CONSTITUTION:The density variation of the electrophoresis pattern from its start to the end is detected by an optical sensor 12 and they are converted to digital data. All the data memorized by a memory 14 is then corrected as to their base value. Then the detection reverses from the end point P to its starting point O of the electrophoresis pattern and the canging values from zero base are obtained. There is a point Q where the shifting value grows larger from the prescribed standard value continuously. This is the end point of measured length of the test sample. The Q point is calculated by counting the whole sampling number from the starting point O to the end point P and the partial sampling number from the end point P to the change point Q. The length of it is obtained from the measurement of the first test sample.
