Title: Protective circuit for thin-film semiconductor
Inventor: ONO KIKUO
IPC: H01L29/786
Filed: 1987-05-20
Abstract: PURPOSE:To cause large leakage currents to flow through a protective transistor by the increase of drain voltage, and to operate a protective circuit excellently by lowering driving gate voltage through hydrogen substitution treatment and composing the protective circuit by using an element having structure, in which hydrogen substitution treatment is difficult to work, in the protective transistor. CONSTITUTION:When a sample substrate is positioned in plasma hydrogen discharge at high frequency in a plane parallel electrode in order to conduct hydrogen substitution in a thin-film transistor Tr1, hydrogen passes through an insulating film 8, the polycrystalline silicon of a gate 7 and a gate insulating film 6, and enters a channel region 2. Consequently, the effect of hydrogen substitution treatment is displayed to the Tr1, and the driving gate voltage of the Tr1 is lowered. On the other hand, a shielding electrode 20 covering the upper section of at least the gate electrode 7 during the manufacturing process of a wiring electrode 5 from the upper section of the protective insulating film 8 is shaped to a protective transistor Tr2. The Tr2 is used as the protective transistor in such structure, thus shielding the intrusion of hydrogen. The protective transistor is shaped in structure in which hydrogen substitution treatment cannot be performed, and a protective circuit is formed by employing the transistor.

Title: Input-output control system
Inventor: ARAI MICHIO
IPC: G06F3/00
Filed: 1977-10-12
Abstract: PURPOSE: To make it possible to accept the only interruption of a channel control block by providing a queue flag to any bit position of a channel control word.  
     CONSTITUTION: When a chain assignment is performed and various processes are continued, it is very important to know the end of the final process through software. An example is to make queue numbers of CCBI to CCB3 large and that of CCB4 small. Although it is possible to vary the reception level of a channel elimination interruption through the alternation of PSW (program status word counter) using a program, interruptions of CCB1 to CCB3 are ignored when this level is high, and the only channel elimination interruption of CCB4 is received. During normal SIO (start) instruction operation, a queue number is transmitted from a CPO to the channel and this becomes the level at the process end

Title: Antenna equipment for reader/writer
Inventor: ISHII HIDEKAZU
IPC: G06K17/00
Filed: 1998-05-01
Abstract: PROBLEM TO BE SOLVED: To efficiently detect a signal sent from an IC card to a reader/writer with respect to an antenna equipment which receives the signal sent from the IC card to the reader/writer in the case that the non-contact IC card and the reader/writer are magnetically coupled by a coil means. SOLUTION: Plural small loop coils 55 to 58 having the same surface area and the same number of turns are so connected that winding directions of small loop coils whose sides are adjacent may be opposite, thus constituting one fundamental coil. These fundamental coils 51 to 54 are arranged in layers while being shifted from each other by a certain length so that sides of small loop coils constituting these coils 51 to 54 don't overlap at the time of projecting them in the passing direction of a magnetic flux in these coils. Thus, a signal from a transmission coil and the noise from the outside can be canceled to efficiently detect only the signal sent from the IC card.

Title: Pulse amplifier circuit
Inventor: KAWADA TOYOSHI
IPC: H03K5/02
Filed: 1982-07-13
Abstract: PURPOSE:To improve the leading response characteristic of an output voltage waveform without incurring the increase in power consumption, by providing a switching element in parallel with a bias supply resistive element. CONSTITUTION:A transistor TRQs being the switching element is connected in parallel with a bias supply resistive element RB. The base of the TRQs is connected to a signal input terminal 3 via a resistor Rs and a capacitor Cs. Further, the TRQs is controlled to on-state an input signal switching a TRQ1 from OFF to ON is changed. As a result, since the TRQ1 is rapidly switched to ON, the leading response characteristic of an output voltae V0 is made steep without decreasing the value of the resistive element RB. Thus, the leading response characteristic of the output voltage waveform is improved without incurring the increase in power consumption.
