Abstract: PURPOSE:To switch two modes through simple operation and to save a space by moving an original placing table upwardly and an optical signal generator to the focal plane of an image forming optical system, and switching a copying mode and a printer mode. CONSTITUTION:When a printer mode switching lever 24 is turned in the printer mode, the original placing table 12 starts to move upwardly. Simultaneously, the optical signal generator 18 moves above a shorter focus lens array 3, and stops when it reaches the center of the optical axis of said array 3.

Title: Data transmission equipment
Inventor: YAMAGISHI TAKASHI
IPC: H04L69/40
Filed: 1986-03-28
Abstract: PURPOSE:To quicken the data transmission and fault detection by allowing a data return means of a slave station to send a return data instantly at the time of an address of the transmission data from a master station is coincident with one's own address and allowing a fault detection means of the master station to detect a fault of the slave station depending on the presence of prescribed in formation of the said return data. CONSTITUTION:A data processing unit 7 of a master station 3 generates a transmission frame RD added with address information of a slave station 5 and sends the result to the desired slave station 5. The address information is compared with its one's own address information from an own station SA generating circuit 55 by an SA coincidence detection circuit 57 of the slave station 5, and when both the information are coincident, the slave station 5 starts a transmission data edition circuit 41 from the circuit 57 instantly from the circuit 57 via a transmission start circuit 47 and returns the return frame SD from a data processing unit 39 to the master station 3. Thus, the transmission of the frame SD is quickened and a fully duplex transmission line 1 is used efficiently. When the slave station 5 is at fault, no frame SD is sent. Such a result is decided by using an FS reception end timeout detection circuit 23 to detect that a prescribed field of the frame SD is not received within a prescribed timeout time by an FS extraction circuit 21.

Abstract: PURPOSE:To set the threshold voltage of an input circuit to a desired value easily, by setting the output of a D/A comparator circuit by a program, and regarding its output value as a reference voltage value for the operation of a comparator. CONSTITUTION:A comparison input voltage is led from an input terminal 10 to the comparator circuit 11. The output voltage of the D/A converter circuit 12 is led as the reference input. This output voltage is given through a data table 13 by a digital input set by a user's in-use program when an integrated circuit is used. When the input voltage is lower than the output voltage, the comparison output of the comparator 11 is at a power supply potential VDD. When the input voltage exceeds the output voltage, on the other hand, the comparison output is at the earth potential. This operation means that the threshold voltage of the input circuit is set to the desired value.

Abstract: PURPOSE:To prevent the occurrence of a smear phenomenon wherein light leaks from a transparent part and a white belt by providing an inter-layer insulating film between a signal line and a picture element electrode and covering the signal line with the picture element electrode. CONSTITUTION:The inter-layer insulating film 10 is formed between a glass substrate 6 where the signal line 1 is formed and the picture element electrode 4 and then the picture element electrode 4 is formed so as to be overlapping with the signal line 1 and an adjacent input line 5 for a gate electrode for a picture element.

Abstract: PURPOSE:To make the characteristic of a transistor uniform for improvement by applying the light beam or the electron beam to the polycrystalline or amorphous semiconductor layer on the substrate surface, before fabricating a transistor on this. CONSTITUTION:A polycrystalline Si layer 3 is provided on a base comprising a semiconductor substrate 1 provided with an insulation layer, and to this, the laser beam is applied from above. Then an MOS transistor having a source 4, drain 5, gate oxide-film 6, gate electrode 7, insulation film 8, and electrodes 9-11 is fabricated. Since the laser irradiation causes many crystal defects and grain boundaries in the polycrystalline Si to disappear, impurities having been trapped by such defects and grain boundaries are electrically activated, so that a great number of electrons or holes are emitted. The mobility is also allowed to rise, so that the electric conductivity rises. In addition, the pressure tightness of P-N junction is allowed to rise, so that the leakage current decreases.
