Title: Air supplying device
Inventor: SUEDA AKIRA
IPC: F24F3/044
Filed: 1991-11-26
Abstract: PURPOSE:To reduce generation of noise by altering a flowing direction of the air to be fed from an air control unit through an opening of a direction different from the flowing direction each time the air flows to a joint duct and a duct. CONSTITUTION:A joint duct 14 is connected to the end of an air control unit 1, a duct 16 is connected to the end of the duct 14, and the air conditioned by the unit 12 is supplied into a room. In this case, the duct 14 is opened in a direction different from the direction of the air to be fed from the unit 12 to alter the flowing direction of the air. Then, a sectional area of a passage is also varied. Further, the duct 16 is also opened in a direction different from the flowing direction of the air to be fed from the duct 14 to alter the air flowing direction. In this manner, the flowing direction of the air is altered to convert noise energy to be propagated through the air, thereby reducing noise.

Title: Output buffer circuit
Inventor: IKEDA YUTAKA
IPC: H03K19/0175
Filed: 1990-11-15
Abstract: PURPOSE:To eliminate a delay in an access time while suppressing ringing by connecting a multi-stage discharge circuit comprising transistors(TRs) to the output buffer circuit. CONSTITUTION:When an input terminal MAI goes to, e.g. L, an output of an inverter 2 goes to H, a TR 4 and a 2nd-stage TR 6 are turned on, and when an output DOUT is high, a gate potential of a 3-rd stage TR 5 is high, and the first half of the discharge of an output buffer comprising 1st stage TRs 3,4 is implemented by the TRs 4, 5 quickly. When the output DOUT approaches a threshold level of the TR 5, the current drive capability of the TR 5 is reduced and then the TR 5 is finally turned off. Thus, the discharge is implemented by the TR 4 only and production of ringing is not occurred. Through the constitution that the discharge speed is changed, while production of ringing is suppressed, the output buffer circuit without a delay in the access time is realized.

IPC: B65H5/06
Filed: 1995-11-30
Abstract: PROBLEM TO BE SOLVED: To provide a paper sheet feeding roller for easily separating an outermost layer paper sheet from a bundle of paper sheets by forming a left and right symmetrical helical protruding part for collecting the paper sheets brought into contact with the outer periphery of the roller at the time of feeding the paper sheets toward its center part.

When the paper feeding roller 1 is brought into contact with the outermost layer of a bundle of transfer paper sheets housed in the paper feeding cassette 5 and rotated, the helical protruding part 6 contacted with the transfer paper sheet of the outermost layer sends out the paper sheets contacted by a frictional force toward the center while collecting the sheets in one side.  This one-side collecting force is applied only to the transfer paper sheets contacted with the helical protruding part 6 and thus only the transfer paper sheet of the outermost layer is separated from the transfer paper sheets of an inner layer. Preferably, the helical protruding part 6 is made of natural rubber, silicon rubber or the like having a high friction factor with the paper sheets.

IPC: H04L1/14
Filed: 1986-12-26
Abstract: PURPOSE:To prevent runaway/malfunction by sending each input data of slave/ master sides to an opposite party and generating each control data synchronously and detecting the coincidence between the transmission content of the slave side and the decoded data of the slave side reception data. CONSTITUTION:A reception data is decoded by a slave side decode section 17 of a slave side reception section 10, the coincidence between the decoded result and the content of slave side transmission is detected so as to synchronize the control data used for the control o the slave side system C with the generation of the control data used for the control of the master side system D. Moreover, the coincidence between the content of the slave side transmission and the decoded data of the slave side reception data is detected to check the entire signal path. Thus, a reset signal is sent from a reset section 21 to a master side D from a slave side C via a slave side transmission section 3 so as to avoid runaway/malfunction of the entire system at a fault (at detection of dissidence) and the slave side itself uses the signal from the reset section 21 to reset the entire blocks.

Title: Insulated gate type semiconductor device
Inventor: SAWADA KENICHI
IPC: H01L29/78
Filed: 1993-12-14
Abstract: PURPOSE:To improve overvoltage-proof strength without generation of lowering of withstand voltage, the blunting of switching time or current concentration breakdown by a method wherein the expansion of a depletion layer due to overvoltage is detected by a sensor consisting of ferroelectric material. CONSTITUTION:A depletion layer sensor 9, consisting of ferroelectric material, is provided on the surface outside the active region of a semiconductor substrate 1, having an active region 10, through the intermediary of an insulated layer 55. The above-mentioned sensor 9 is connected to a gate 6. When the overvoltage in excess of rated withstand voltage is added between output terminals, the depletion layer 14, corresponding to the above-mentioned voltage value, begins to expand to substrate end part from the active region 10 of the semiconductor substrate 1. Voltage is induced by the movement of the carrier discharged to substrate end direction by the expansion of the depletion layer 14. This induced voltage is amplified by a driving circuit when necessary and applied to the gate 6 as a voltage signal. As a result, overvoltage is absorbed by the entire substrate as a current.
