Title: Sample holding circuit
Inventor: YUGAWA AKIRA
IPC: H03K17/00
Filed: 1986-07-17
Abstract: PURPOSE:To minimize an off-setting voltage and to remarkably decrease an output voltage change in a sample holding action by balancing the channel of a signal. CONSTITUTION:The circuit is composed of a balance type operational amplifier A having a differential input and a differential output terminal, capacitors CN and CP having an equal capacity value, pairs SN and SP of a switching means, the pair of resistances R1N and R1P having an equal resistance value R1 and resistances R2N and R2P having an equal resistance value R2. In a voltage following mode, since an input bias current to the operational amplifier is approximately equal to the differential input, it can be expected that by the same phase removing action of the operational amplifier, the input voltage change by the bias current does not appear at the output, and next, when switches SN and SP are opened and a voltage holding mode is obtained, the voltage of nodal points 5 and 6 is changed by the presence of the bias current of the operational amplifier, and since the bias current is approximately equal and the changing quantity is equal, the change does not appear at the output terminal by the same phase removing action of the operational amplifier.

Title: System for data synchronization between server in decentralized server constitution
Inventor: TAKAHASHI TERUO
IPC: G06F15/177
Filed: 1999-06-16
Abstract: PROBLEM TO BE SOLVED: To actualize a recovery process for data synchronism in the case of fault occurrence by load decentralization by allowing a master server to request a slave server to update data when the slave server is available and updating the data on the server when the data modification by the slave server ends normally. SOLUTION: When a request to update synchronous data is generated, the master server 41 issues an updating request to the slave server 42 before updating its data since the slave server 42 is registered on this server 41. The slave server 42 sends an answer 47 to the updating request 44 back to the master server 41. The master server 41 updates its data when the answer 47 from the slave server 42 is normal. Then the slave server 42 having received the updating request 44 issues an updating request 45 to a server 43 similarly since the server 43 is registered as a slave server on the server 42. The server 43 is a link-terminal server since no slave server is registered. The server updates its data through a similar process as well.

Title: Tentering device of sheet housing tray
Inventor: TANIGAWA SADAO
IPC: B65H31/20
Filed: 1990-06-26
Abstract: PURPOSE:To raise the image forming speed by setting the standard position of a movable plate between the maximum width size and the minimum width size of sheets to be used. CONSTITUTION:A movable plate 33 is moved a specific amount from a standard position corresponding to the size of sheets to be housed. As a result, the side ends of the sheets stocked in a housing tray 23 are regulated by the movable plate 33, and the tentering is carried out. In this case, since the standard position of the movable plate 33 is set between the maximum width size and the minimum width size of the sheets, the moving amount for tentering is smaller than in the conventional device whose standard position is set at the outer side of the maximum width size. Consequently, even when it is applied to a high speed image forming device, the restriction of image forming time for tentering time is little. The image forming speed is raised, accordingly.
