Title: Developing device
Inventor: NISHIMURA KATSUHIKO
IPC: G03G15/09
Filed: 1993-07-09
Abstract: PURPOSE:To provide a developing device constituted so that an image carrier is prevented from being damaged by a developer carrier when an image forming device is transported and a defective image caused by the damage of the image carrier from being formed even when a gap between the developer carrier and the image carrier of the image forming device is made narrow. CONSTITUTION:The developing sleeve 30 of the developing device is constituted by providing an electrical conductive elastic layer 34 whose hardness is lower than a photoreceptor drum and whose volume resistivity is <=10<8>OMEGA.cm on an electrical conductive non-magnetic substrate 32 as an outside layer. Thus, even when the sleeve 30 is brought into contact with the photorecepter drum caused by vibration at the transporting time of the image forming device incorporating the developing device, the surface of the photoreceptor drum is prevented from being damaged and the defective image caused by the damage of the photoreceptor drum is prevented from being formed.

Title: Rack and pinion type power steering
Inventor: SUZUKI KATSUHIRO
IPC: B62D3/12
Filed: 1981-12-02
Abstract: PURPOSE:To make it possible to obtain a joint-to-joint distance necessary for minimizing toe variation, by connecting one joint to the opposite end of a cylinder and the other joint to an intermediate position between the cylinder and a rack. CONSTITUTION:A rack 27 moves in either one of directions when a pinion 29 is rotated by turning a steering wheel 31. For example, when the rack 27 moves to the left, high pressure is fed to a right cylinder chamber 40B, and therefore, a piston rod 22 moves to the left while being subjected to power assist due to hydraulic pressure. Thereby side rods 26A, 26B which are connected to the pison rod 22 through ball joints 25A, 25B displace to the left, identically, for changing the direction of wheels. In this case, the joint-to-joint distance A0 is not the distance between both projecting ends of the cylinder 22, but one joint is connected to the one end of the cylinder and the other joint is connected to an intermediate position between a cylinder part 30 and the rack 27 so that the joint-to- joint distance A0 may be easily set in an optimum distance for minimizing toe variation.

Title: Small arced mold for continuous casting
Inventor: MATSUOKA TOSHIKI
IPC: B22D11/05
Filed: 1981-12-04
Abstract: PURPOSE:To change the range of casting widths without replacing short side mold pieces by disposing the short side mold pieces having tapered inside surfaces freely adjustably between the long side mold pieces provided with small arced inside surfaces. CONSTITUTION:Short side mold pieces 6, 6 having tapered inside surfaces 7 in tight contact with both side surfaces of long side mold pieces 4F, 4L provided with small arced inside surfaces of a small radius having a center on the horizontal extension line at approximate center in the height of a mold 1 are disposed between said long side mold pieces. In this state, the inside surfaces 7 of the pieces 6 have the tapered surfaces that meet the allowances for the breadthwise shrinkage of the casting width. In the case of changing the casting with, the pieces 6, 6 are moved parallel by supporting mechanisms for short sides and in succession, the pieces 6, 6 are tilted to change the tapered inside surfaces 7. As a result, the increase in the clearance between the contact surfaces of the piece 6 and the piece 4F is effectively prevented and the range of the casting width of the small arced mold with respect to the conversion to the low head of continuous casting machines is adjusted to an about 1,000-2,000mm. range.

Title: Ac vector detector
Inventor: KITAYOSHI HITOSHI
IPC: G01R27/28
Filed: 1990-07-23
Abstract: PURPOSE:To enable improvement in stability and accuracy of measurement by providing a polarity switching means which make polarity of a phase detection output signal to be applied to an integrator invert at each integrating action to allow the removal of a dielectric absorption electric charge. CONSTITUTION:Integration voltages of integrators 5A and 5B are reset each time switches SHS3 and S6 are turned ON and this resetting cycle corresponds to one integration cycle. An integrating operation is performed when the SHS2 and S5 are ON while the S1 and S4 are OFF. When the integrating operation ends with the S2 and S5 turned ON back, the SHS8 of an polarity switch 9 is operated. Interlocking the switching, output signals of phase detectors 4A and 4B are inverted to negative from positive and as a result, an integration voltage is inverted in polarity at each action. The voltage integrated is converted 6 into digital from analog and an arithmetic device 7 performs a computation to average the preceding and present measured values. Thus, this switching of the polarity at each integrating action removes a dielectric absorption electric charge in integration capacitors C1 and C2. This also allows the canceling and removal of leak errors or the like by the averaging computation with the arithmetic device 7.

Title: Acquisition system
Inventor: MIYASAKA AKIRA
IPC: H04J3/00
Filed: 1983-10-18
Abstract: PURPOSE:To accelerate the acquisition of bursts by finishing the intial acquisition as long as the acquisition is possible even with one of initial acquisition bursts which are transmitted from a ground station every burst and returned by the satellite relay. CONSTITUTION:A standard burst is extracted by a demodulator DEM after the burst ratio waves received from a standard station through an antenna ANT are amplified by a low noise amplifier LN-AMP together with conversion of frequency. A synchronizing pulse showing the rise point of the reference burst is produced at a frame synchronizing part F and an SYNC and applied to a burst position control part BP-CONT. Then an IAB transmission pulse showing the rise point of an initial acquisition burst is produced based on the time difference from the time slot of own station and applied to IAB-DET1-3. These IAB-DET 1-3 produce the initial acquisition bursts, and these bursts undergo frequency conversion through a modulation part MOD. Then the bursts are transmitted to a satellite repeater from the ANT via a large electric power amplifier HP-AMP.

IPC: G01B7/02
Filed: 1984-09-18
Abstract: PURPOSE:To predict more accurately and speedily the deformation and destruction of the ground by connecting joint parts of measurement pipes of unit length through rotary joints and slide joints to necessary length, and installing an angle sensor which detects an angle of rotation and an extension sensor which detects a slide quantity. CONSTITUTION:A necessary number of measurement pipes 1 are connected mutually to necessary length by using a rotary joint 2 and a slide joint 3 at a node between a couple of pipes and used while buried perpendicularly in the boring hole at a place to be measured. If the ground slants or rotates to deform, the inclination between two adjacent measurement pipes 1 and 1 causes the angular displacement of the rotary joint 2 and appears as the relative angular displacement between a bracket 6 and a connecting part 8. This angular displacement is detected as the angle of rotation of the input shaft pulley 4a of the angle sensor 4. If the ground is displaced perpendicularly, it causes extension or contraction between two upper and lower adjacent measurement pipes 1 and 1 to displace the slide joint 3, which is detected a s the angle of rotation of the input shaft pulley 5a of the angle sensor 5.
