Title: Multiple disk clutch using electroviscous fluid
Inventor: INOUE AKIRA
IPC: F15B21/06
Filed: 1988-03-30
Abstract: PURPOSE:To maintain good torque transfer performance by holding each spacer made of an insulating material among multiple input clutche disks, and forming each of projections, being opposed to output clutche disks at regular intervals in the axial direction, solidly with the spacer as one body, in a clutch which utilizes an electroviscous fluid as a torque transfer medium. CONSTITUTION:In a clutch which utilizes an electroviscous fluid L as a torque transfer medium, each space made of an insulating material is held among multiple input clutch disks 7, and each axial position and mutual intervals of the input clutch disks 7 are fixed. In addition, each projection 12a, being opposed to each output clutch disk 16 at regular intervals in the axial direction, is solidly formed with the spacer 12 as one body. With this formation, an interval C1 between these input and output clutch disks 7, 16 can be set as small as possible owing to these spacers 12 and projections 12a, and that both clutch disks 7, 16 are made keepable so as not to come into contact with each other. Therefore augmentation of transfer torque by means of multiplication of the clutches is achievable, thus good torque transfer performance is maintainable.

Title: Destaticizing method of photoreceptor in copying machine
Inventor: NISHIJIMA HIDEYO
IPC: G03G21/06
Filed: 1978-06-30
Abstract: PURPOSE:To decrease the DC components and reduce the dispersion of photoreceptor residual potential, by destaticizing the photoreceptor after image transfer in an electrostatic copier by controlling the bias voltage of DC power source of corona discharger for destatizization. CONSTITUTION:As shown in figure (a), when the DC components IAC in the corona discharger for destaticization of photoreceptor are constant (for instance, 180muA), if the DC components IDC decrease, the residual potential also decreases, and the dispersion thereof becomes smaller, too (the solid line refers to the standard potential, the broken lines mean the maximum and minimum potentials). Therefore, by connecting a DC power source 3 to the AC power source connected to the wires of a charger 1 and applying a DC bias voltage, the dispersion of the residual potential may be reduced (figure b). Also, instead of the DC power source 3, a diode 4 and a Zener diode 5 may be used to obtain the same purpose (figure c).

Inventor: YAMAUCHI MASAMICHI
IPC: G04C10/04
Filed: 1979-06-26
Abstract: PURPOSE:To prevent malfunctioning of the counting circuit by indicating the warning during the use of the counting circuit in response to the access of other functions in the multi-functional circuit while it is operating in one function. CONSTITUTION:When the mode selection switch S4 is depressed, the output of the mode selection shift register 3 is turned to the high level and with the stop watch mode, the and gates 7 and 9 and the like are opened. Under such a condition, with the depressing of the stop watch functioning switch S3, the multi-functional counter 21 starts counting, bringing the stop watch into the working state, where the discrete value of the counter 21 is indicated on the display 23 through the indication switching circuit and the decoder/driver 22. On the other hand, under such a condition, when other stop watch function is accessed by depressing the switch S4, the output of the and gate 17 turns to the high level through FF 11 and is applied to the driver 22. Thus, the warning mark is indicated on the device 23 thereby preventing malfunctioning of the multifunctional counting circuit.

Title: Manufacturing method of enclosed alkaline battery
Inventor: SHINAGAWA TOMOYUKI
IPC: H01M10/28
Filed: 1982-05-12
Abstract: PURPOSE:To secure a battery excellent in reliability by the way of meeting the following requirements that being high in the density of volumetric energy and its plate groups are all firmly secured to the specified position and that there is no deterioration in battery characteristics attending upon a plate shear in time of flanging for a cell case or the spattering of impalpable powder of an active material. CONSTITUTION:A positive pole 3 is piled up on a separator 2 whose outer diameter is larger than the inner diameter of a cell case 9 in advance and, after both are placed on a case opening end 9b, both 3 and 2 are thrust into the cell case 9 by forcibly pressing the former 3. In this process, smoothness past between the separator 2 and the cell case 9 is good enough so that even if the outer diameter of the positive pole 3 enlarges up to the limit in full, the separator 2 can be smoothly inserted into the case 9. Furthermore, the separator 2 is rich in elasticity whereby there is no fear of damaging the separator depite minute burrs of a core material 3a remaining on a frequency peripheral surface 3b at the positive pole side and on the contrary, fibers of the separator 2 are entangled with these burrs, curving a slip of the positive pole 3 which therefore can be firmly secured to the cell case 9 inside. After inserting the positive pole 3, the peripheral part 2a of the separator 2 forms a cup-shaped vessel to open when it rises along the inside wall of the cell case 9.

Title: Wear preventing device for bent pipe
Inventor: ISHIHARA TAKESHI
IPC: B65G53/52
Filed: 1993-04-07
Abstract: PURPOSE:To prevent powder/grain from colliding directly with the inner wall of a bent pipe so as to suppress wear and thereby to enable the long-term use of the bent pipe by providing a compressed gas injecting means at a part with which the powder/grain collides in the bent pipe for transferring the powder/grain. CONSTITUTION:The upper reaches end part of an outer part A in the radius-of- curvature of a bent part where ash collides with the pipe inner surface in a bent pipe 1 is provided with a compressed air injection nozzle 2 connected to a compressed air source. The tip 2a of this nozzle 2 is opened to a part in the circumferential direction of the bent pipe 1. The ash transferred by air in the direction of an arrow mark (a) thereby collides with an air layer 5 first so as to be transported downstream along the flow of compressed air. The ash is therefore prevented from colliding directly with the inner wall of the part A of the bent pipe 1. As a result, there is no wearing part in the bent pipe 1, so that the bent pipe 1 can be used over a long period of time.

Abstract: PROBLEM TO BE SOLVED: To provide a means with which the position of a vehicle can be detected in a short time by improving the accuracy of the position detection by a magnetostrictive vibrator. SOLUTION: When transmission outputs are impressed to winding wires L3S-L7S for transmission commonly wound around bar antennas 3-7, electromagnetic waves are simultaneously radiated from the bar antennas 3-7, a magnetostrictive vibrator 1 is excited by this waves to pass the vibrator 1, an electromagnetic wave is generated from the excited magnetostrictive vibrator 1, and the line of magnetic force composed of this wave is similarly generated. When received signals respectively generated on reception coils L3R-L7R of the bar antennas 3-7 are detected while switching the outputs at the timing of reception, the strongest electromagnetic wave from the magnetostrictive vibrator 1 is applied to the bar antenna 5 closest to the magnetostrictive vibrator 1, and the maximum received signal output is generated on the reception coil L5R.  Therefore, the position of the magnetostrictive vibrator, namely, the position of a bar antenna group corresponding to it can be known.
