Title: Connection of multilayer film
Inventor: MORIHARA ATSUSHI
IPC: H01L21/60
Filed: 1988-09-21
Abstract: PURPOSE:To simplify mounting and reduce cost by directly connecting a chip and a substrate through a plurality of films C of intermediate coefficient of thermal expansion between a film A and a film B with the same coefficient of thermal expansion as that of chip and the substrate. CONSTITUTION:A multilayer film 5 is formed of a film A with the same coefficient of thermal expansion as that of a chip 1, a film B with the same coefficient of thermal expansion as that of a substrate, and a plurality of films C with an intermediate coefficient of thermal expansion and the chip 1 and the substrate 3 are directly connected through a pin 9. When power is supplied to the chip 1 through the pin 9, the chip 1 expands thermally but no shear stress occurs in a solder ball 2 since the film A equally expands. Also, no shear stress occurs in a pin pad 10 by the film B for expansion of the substrate 3 and the difference in coefficient of thermal expansion between the films A and B is relaxed through the film C. It allows the chip and the substrate to be connected directly, simplifies mounting, and then reduce cost.

Title: Logic electronic circuit device
Inventor: YAMAMOTO MITSURU
IPC: H01L51/05
Filed: 1985-10-23
Abstract: PURPOSE:To obtain a logic circuit device which can record and delete programs, by connecting first electrodes in lines to second electrodes in rows at their intersections through a film containing a charge-transfer complex compound. CONSTITUTION:A substrate 34 is provided thereon with first electrodes (of copper) 31 extending longitudinally and dipped in a saturated acetonitrile solution of TCNQ (tetracyano-quinodimethane) so as to form a Cu-TCNQ complex film on each of the electrodes 31. Second electrodes 32 are then formed on the substrate and the complex films so as to extend transversely, by vapor depositing aluminium. When a voltage higher than a critical voltage VC is applied between electrodes at arbitrary intersections (e.g. between the electrodes 31-a and 32-1), the complex films at these intersections are allowed to have diode characteristics, while the complex films at the remaining intersections are maintained in the highly resistive state. A programmable logic circuit can be obtained in this manner. Further, the programmable logic circuit thus produced can delete a program by heating the entire elements to 50-150 deg. so as to return all the intersections to the highly resistive state.

Title: Data transmission system
Inventor: SONEHARA NOBORU
IPC: H04L1/00
Filed: 1983-12-16
Abstract: PURPOSE:To prevent degradation of transmission efficiency by using the number of retransmission request signals received in a certain number of transmission frames to estimate the quality of transmission and not determining a fixed information data length to a communication device but changing the information data length in accordance with the estimated value. CONSTITUTION:A transmitter 1 inputs information data ID to a transmission frame generating circuit 10 to constitute an information frame, and it is transmitted from a transmitting circuit 11 to a communication line 3 through a network control circuit 12. A receiver 2 receives this information frame; and if it is detected by an error detecting circuit 24 that error data is included in the information frame, a monitor signal transmitting circuit 25 is started to transmit a monitor signal of retransmission request to the communication line 3 through a transmitting circuit 21 and a network control circuit 22. The transmitter 1 counts the number of transmitted information frames by the first counting circuit 14. Meanwhile, the monitor signal of retransmission request transmitted from the receiver is inputted from a receiving circuit 13 to the second counting circuit 15 and is counted. A comparing circuit 16 uses both counted values to generate a parameter (Y). The transmission frame generating circuit 10 changes the data length of transmission in accrodance with this parameter (Y).

Title: Driving method for solid-state image pickup device
Inventor: SONE KENRO
IPC: H04N5/335
Filed: 1985-10-22
Abstract: PURPOSE:To prevent an abnormal signal from being mixed in a picture by discharging an unnecessary signal change from an output part disposed separately from a signal charge detecting circuit at the time of the operation of an electron shutter. CONSTITUTION:The unnecessary signal charge which is not used as a video signal accumulated in a period 14 in a photoelectric transfer part until then is transferred to a vertically transferring part 2 by using the first charge pulse 11 during a vertical fly-back period. Then, the vertically transferring part 2 is driven in a direction opposite to an arrow during a period 13 and all the signal charges in the vertically transferring part 2 are transferred to an output part 5 disposed at one end of the opposite direction to a horizontally transferring part. In the output part 5, all the transferred signal charges are thrown away. Thereafter, the signal charge accumulated in the period 13 in the photoelectric transfer part 1 after the first charge pulse 11 is transferred to the vertically transferring part 2 by the second charge pulse 12. As a result, during a period 17, unnecessary signal output is not outputted from a solid-state image pickup element.

Title: Fixing device for image forming device
Inventor: NAKAMURA SHOJI
IPC: G03G21/00
Filed: 1990-09-05
Abstract: PURPOSE:To obtain an excellent image without having irregularities in fixing caused by the deformation of a heating roller by normally separating a pair of separable rollers, and press-welding them each other when a recording sheet passes. CONSTITUTION:The recording sheet carried to a resist roller 41 is detected by a paper feeding sensor 70, and a control circuit 72 energizes a solenoid 67. When the solenoid 67 is energized, the heating roller 62 separated in a stand-by state is press-welded to the roller 61, by a turning action, and heated while being rotated and driven, and a toner image on the recording sheet is fixed to the recording sheet. When the recordings sheet is ejected from a fixing device 60, a paper ejecting sensor 71 detects the recording sheet. However, the sensor 71 does not detect the recording sheet, the controlling circuit 72 stops the energization of the solenoid 67. Thus, the roller 62 is separated from the roller 61 by the turning action. Therefore, the rollers 61 and 62 are not continuously press-welded for a long time, and it is not feared that a periphery is deformed, but the irregularities in the fixing caused by the deformation do not occur.

Abstract: PROBLEM TO BE SOLVED: To make it possible to suppress an operation ever of an event to a minimum within a short time. SOLUTION: A control system for an event (system, machine, action and so on) that operates by being given a control commend is provided with a simulator means 30 for simulating an operation of the event, a correction means 40 for bringing the simulation result close to a target value, and a virtual display means 50 by a virtual reality for visualizing the event such as a present operation condition of the event, a monitor of a prediction result of the operation condition or the like that actually cannot be visualized. Thus, even when the operation of the event deviation from the target value because of a variety of external factors such as an environmental condition of the operation of the event or the like, the operation errors can be suppressed to a minimum by predicting at once the operation and the future at an arbitrary point of time, monitoring and correcting them.
