Filed: 1995-03-13
Abstract: PURPOSE: To effectively suppress increase in memory capacity while preventing necessary calculation time from becoming longer by calculating a motion equation by using a reduced matrix of another space. CONSTITUTION: When the coupled vibration of the structure and fluid at a flow place for analyzing a phenomenon wherein the structure and fluid vibrate while mutually applying forces by a finite element method by representing the phenomenon by a motion equation is calculated, the vibration mode of the flow place is calculated by the vibration mode of a stationary place, series expansion is performed, and the constituent matrix in the motion equation is calculated by using the constituent matrix of a matrix representing the influence of the fluid and converted into the reduced matrix of another space, thereby calculating the motion equation by using the reduced matrix of another space. The motion equation in this case can be represented by an expression.  In the equation, M, K, and C are matrixes of the structure, Ma, Ca, and Ka are matrixes representing the influence of the flow velocity, and Caτ and Kaτ are matrixes representing the influence of shearing stress by the viscosity of the fluid.

Title: Image forming device and its maintenance method
Inventor: KURODA YUJI
IPC: G03G21/00
Filed: 1997-02-21
Abstract: PROBLEM TO BE SOLVED: To relieve an error occurred in an image forming device for informing the error to an external device based on the registered priority in the case the error is detected. SOLUTION: The user uses an operation panel 440 to set a registered number of host computers connecting to a network, a registration number and a release time to an NVRAM 407. On the occurrence of an error in a printer engine 430, an engine controller 420 sends an error status to a CPU 402. The CPU 402 confirms its content and references the NVRAM 407 to retrieve to which host computer the error information is able to be sent, connects to a host computer 410 registered at first and sends the error information to the host computer 410. When the CPU 402 confirms that the error is relieved within a setting time of the relief timer, the CPU 402 terminates transmission of error information. When no power is applied to the host computer 410, the CPU 402 tries to connect to a host computer 411.

Title: Formation of electrostatic latent image
Inventor: KANBE JIYUNICHIROU
IPC: G03G5/00
Filed: 1980-04-21
Abstract: PURPOSE:To form an electrostatic latent image on a photoreceptor surface, by pressing the photoreceptor formed by covering a photoconductive layer with an insulating layer, and a transparent semiconductor belt with primary and secondary conductive rollers, moving them, and imparting continuous potential distribution along the moving direction. CONSTITUTION:Insulating layer 1c is positively charged with high voltage roller 4 to trap negative charge on the interface between photoconductive layer 1b and insulating layer 1c, and positive charge on layer 1c is removed with low voltage rollers 5, 6 to trap positive charge on the interface between drum 1a and layer 1b. Transparent semiconductive belt is passed between drum 1a and rollers 5, 6 to perform imagewise exposure 13. The negative charge on the interface between layer 1b and layer 1c is eliminated in light L, and the positive charge on drum 1a corresponding to negative charge disappears, and in dark D, part of the positive charge  disappears. Then, photoreceptor 1 is uniformly exposed 14, permitting surface potential to be kept constant in light L, the negative charge on layer 1b to disappear in dark D except that corresponding to the positive charge on layer 1c, and the  surface potential in dark D to become higher than that in light L, and thus an electrostatic latent image to be formed.

Title: Base board carrier
Inventor: SHIMA YASUMASA
IPC: G02F1/1333
Filed: 1995-03-13
Abstract: PURPOSE: To provide a base board carrier wherein no carrying failure occurs because of deflection due to the self weight of a carrying roller even when a large size base board is carried. CONSTITUTION: A cleaning tank is constructed in such a manner that a pair of side plates 2a and 2b are arranged keeping a fixed distance between each other. Roller bearings 40 and 40 are attached to the positions opposite to each other of these side plates 2a and 2b and a carrying roller shaft 60 is supported in the horizontal direction so as to be freely rotated. In this case, since the center side of the shaft 60 is composed of a hollow pipe section 64, deflection produced due to the weight of the center side of the carrying roller is reduced. Thus, tilting of rollers 70 and 70 with steps provided for supporting a base board W in the shaft 60 is prevented and the generation of carrying failure is prevented by preventing the supporting failure of the base board W during carrying.

Further, the resistance value of the current limiting resistor 105 at recording is controlled to an optimum value corresponding to every recording medium and according to the type and the film of the recording medium, and stable information recording is performed regardless of the film thickness and the type of the recording medium.

Title: Semiconductor integrated circuit
Inventor: SAKAI HIROYUKI
IPC: H03K19/0952
Filed: 1989-03-06
Abstract: PURPOSE:To realize a stable source coupling FET logic (SCFL) circuit whose current is unchanged depending on the number of stages of longitudinally stacked gates by applying a proper level shift to a current source FET whose number of stages of longitudinally stacked gate and whose source-drain voltage is increased to match the level with the source-drain voltage of the current source FET having many number of stages of longitudinally stacked gates. CONSTITUTION:While 3-stage of longitudinally stacked gates connect to a drain of a current source FETQA of a NOR incorporating part, number of stages of longitudinally stacked gates connecting to drains of FETs QB,QC is respectively 2 stages and 1 stage only, and diodes 1 (DA,DB,DC) applying level shift are connected to drains of the TRs QB,QC. However, in response to the number of stages of longitudinally stacked gates, number of level shift diodes is adjusted to make the source-drain voltage of the diodes QA, QB, QC nearly equal to each other. Thus, the stable SCFL circuit whose current is unchanged is realized independently of the number of stages of the longitudinally stacked gates.
