Title: Electrophotographic device
Inventor: KINOSHITA SHOICHI
IPC: G03G15/16
Filed: 1995-11-30
Abstract: PROBLEM TO BE SOLVED: To prevent the deterioration of printing quality due to paper powder generated from a recording paper and to maintain good printing quality even in the case of changing the width of the paper, by installing a shielding member for shielding the side edge part of the recording paper between a photoreceptor and a transfer/electrostatic charger. SOLUTION: At the time of transferring the toner image on the photoreceptor drum 2 to the surface of the paper 5 by the transfer/electrostatic charger 6, the right edge part of the paper 5 is shielded by the shield plate 14. That is, corona transfer is partly shielded so that a transfer current may not flow between the drum 2 and the charger 6, then, the paper powder is prevented from sticking to the surface of the photoreceptor drum 2 even in the case the paper powder sticks to the right edge part of the paper 5. Thus, even in the case of changing the width of the paper 5 from the narrow one to the wide one, black stripes are surely prevented from being printed on a position corresponding to the right edge part of the paper 5 before the paper is replaced.

Title: Box shaped buffer material for packaging
Inventor: UEDA YASUSHI
IPC: B65D81/113
Filed: 1988-12-13
Abstract: PURPOSE:To prevent the fracture of a material due to surface compression by a method wherein a groove shaped recessed part is formed on the inside of an edge at a corner which is formed by joining the contact surfaces, to an object to be packaged, of box side wall parts and box bottom wall part, etc. of a box shaped buffer material. CONSTITUTION:When a buffer material is placed over an object to be packaged and is made to surface-fall in such a manner that, e.g., a surface compression force is added in the direction of thickness of a surface 8c, the weight of the packaged object presses the surface 8c, and the compression force is made to work in the direction of the thickness, and a compression deformation is given. However, since a groove shaped recessed part 2 is provided, surfaces 8b, 8d, 8e, which are adjacent to the surface 8c, are separated from the surface 8c by this groove shaped recessed part 2, and shearing stress does not generate at the edge part. Therefore, fracture such as crack, etc. hardly occurs at the edge. Also, when the title buffer material edge-falls in such a manner that an edge which is formed by the surfaces 8c and 8b hits the ground, a leg opening moment is added and the surfaces 8c and 8b are pressed to open. However, since the groove shaped recessed part 2 exists, the title buffer material can deform at the edge part accommodating itself to the leg opening moment. Therefore, fracture of the material hardly occurs.

Filed: 1990-11-19
Abstract: PURPOSE:To reduce the dimension of a chassis dynamometer device and reduce cost by mechanically connecting the shaft of a revolution roller for placing the tire of a test vehicle and the shaft of a flywheel through a speed change mechanism. CONSTITUTION:A speed change mechanism 5 converts the revolution of a revolution roller 1 to the pulse signal of an input shaft speed detector 6 by a frequency/voltage converter 15. When the signal exceeds a certain value, the set speed change ratio (k) supplied by a speed change ratio setting device 13 and the speed change position detecting signal (actually measured speed change ratio (k)) detected by a speed change position detector 9 are compared-calculated by a calculator 11, and set to an aimed speed change position by a pilot motor 8. The actually measured speed change ratio (k) of the controlled speed change mechanism 5 is monitored at all times, and controlled so that the actually measured speed change ratio (k) accords with a set speed change ratio K in the increased speed region for a test vehicle, and the arbitrary inertia quantity is obtained continuously. In this case, the inertia quantity observed from the shaft 3 side of the roller 1 can be set to k<2> times of the inertia quantity of a flywheel (g).

Title: Scroll compressor
Inventor: UCHIKAWA NAOSHI
IPC: F04C29/00
Filed: 1987-12-11
Abstract: PURPOSE:To improve the reliability of a bearing by arranging a balance weight near a swivel scroll for producing centrifugal force thereby reducing the weight without complicating the shape and relieving the bearing from load. CONSTITUTION:When a crank shaft 4 is rotated through a motor, a balance weight 7 is balanced with centrifugal force being produced through swivel motion of a swivel scroll 2. Since a balance weight is arranged near the swivel scroll 2, the effectiveness of the balance weight is improved and the weight thereof can be reduced, while since the balance weight is fixed perpendicularly to the crank shaft 4, no moment functions onto the fixing section thereby the shape thereof can be simplified. Furthermore, since a center crank having upper and lower main bearing 20, 22 is employed, it causes no shifted contact thus improving the reliability. Since the thrust shaft 31 of the crank shaft 4 is not enlosed, it is not bitten by a foreign matter in oil.

IPC: F02D45/00
Filed: 1987-12-14
Abstract: PURPOSE:To make disconnection and short-circuiting in a sensor system diagnosable in a short time by impressing an electric signal on the sensor as long as the specified time from a controller. CONSTITUTION:When a rectangular wavy signal is outputted to an oxygen sensor 1 being connected to an input terminal of a microcomputer 4, voltage conformed to impedance of the oxygen sensor 1 is induced to the input terminal. This signal is detectable while the rectangular wavy signal is being outputted from the microcomputer 4. Consequently, this value is monitored whereby a state of the oxygen sensor 1 is thus diagnosable.

Title: Semiconductor integrated circuit device
Inventor: KISHI ATSUSHI
IPC: H01L21/60
Filed: 1986-12-24
Abstract: PURPOSE:To shorten the separation between an aluminum-pad electrode and an internal aluminum wiring group by arranging a slitty through-hole to the whole surface or only central section of a bonding surface in the aluminum-pad electrode in two dimensions. CONSTITUTION:When an aluminum-pad electrode 4 is disposed just above an impurity diffusion layer 2, slitty through-holes 7 absorb the greater part of bonding stress generated at that time and are crushed when bonding work is conducted onto the aluminum-pad electrode 4. Consequently, the greater part of bonding stress is consumed on the surface of the aluminum-pad electrode 4, thus extremely reducing propagation force directed toward an aluminum leading-out conductor section 6 and the impurity diffusion layer 2 just under the section 6. That is, elongation in the transverse direction of the aluminum leading-out conductor section 6 is relaxed remarkably, and a junction shaped by the impurity diffusion layer 2 is protected from its own breakdown. Accordingly, a separation L between the aluminum leading-out conductor section 6 and an adjacent internal aluminum wiring can be shortened.

Title: Semiconductor storage device
Inventor: MURAKAMI SEIJI
IPC: G06F12/16
Filed: 1992-11-25
Abstract: PURPOSE:To reduce the mounting area of a semiconductor storage device to increase the operation speed by switching a parity/ normal switching circuit to perform the parity check. CONSTITUTION:At. the time of the normal mode, 9-bit data inputted to input terminals 101 to 109 are written in a memory cell 110i through a DQW buffer 112 and are read out to terminals 101 to 109 through a DQR buffer 113. Meanwhile, when the control signal from a control signal input terminal PN is set to H, a switching signal phi from a switching signal generating circuit 170 turns to L and parity/normal switching circuits 130 and 150 are switched to parity, and the parity is written in an array 110 by the 8-bit input and a parity calculating circuit 120. At the time of read, the parity calculated from 8-bit read data by a parity calculating circuit 140 and the parity read out from the array 110 are compared with each other by a coincidence/discordance circuit 160. Thus, it is unecessary to externally adhere parity calculating circuits or the like, and the mounting area is reduced to increase the operation speed.
