Title: Semiconductor substrate cleaning liquid and cleaning method
Inventor: KUBOTA MICHITAKA
IPC: H01L21/304
Filed: 1997-04-08
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor substrate cleaning liq. and cleaning method which suppresses the growth of a natural oxide film after cleaning to produce a semiconductor device superior in characteristics. SOLUTION: An Si substrate is cleaned with a cleaning liq. composed of a mixture of deuterium fluoride with heavy water to remove the oxide film from the substrate surface and terminate free bonds of Si atoms with deuterium only. Deuterium more tightly bonds to the Si atom than to H, and hence there is little free bond of Si atom or Si atom scarcely recombines with deuterium after breaking of the bond, thus suppressing the growth of the natural oxide film, etc., on the cleaned Si substrate surface.

Title: Network control system
Inventor: AKUTA SHIYOUJIROU
IPC: H04L29/08
Filed: 1980-08-01
Abstract: PURPOSE:To eliminate the manual switching operation, by changing the call connection to the MODEM connection after receiving the push-button dial signal or the multi-frequency selection signal. CONSTITUTION:When a subscriber A gives a start to a central controller CC, a network controller NCU of a subscriber B is called out. The NCU through which the called subscriber B replies sends a reply back to a generak telephone exchange network T to secure a talking state between the subscribers A and B. When the switching is given to a data communication, the calling subscriber A supplies a switch command to the controller CC. The controller CC starts a push- button dial signal oscillator PBOST to transmit a switch code for the switching to the data communication. This signal is received at a push-button dial signal receiver PBREC via the NCU of the subscriber B. Receiving this information, the controller CC switches a channel controller SPT to a MODEM device MD. When the exchange of information is over, the connection of the NCU is switched again to the controller SPT.

Title: Automatic informing device
Inventor: IWAKI KAZUHIKO
IPC: H04Q9/00
Filed: 1987-05-01
Abstract: PURPOSE:To automatically inform guage examination data on the fixed date of every month by comparing time data and date data with data stored in an informing date data memory means, deciding whether the both data agree with each other or not with the aid of a deciding means and informing generating information with the aid of information generation means when they are decided as agreed with each other. CONSTITUTION:The informing date data set in the prescribed area of an RAM 31b and the present date data read from a clock and a calendar 33 are compared and whether it is the message date or not is decided. When the present date is the informing date, the time data is compared. When they are decided as agreed with each other, an informing factor generation flag to inform the automatic guage examination is stood. Then a telephone line is checked whether it is occupied or not according to the state of input ports I6 and I7. When it is idle, the line is catched by outputting a signal to output ports O3 and O4 and simultaneously to that, a dial is operated by outputting a dial signal from an input-output port IO. Thus as the guage examination data can be sent on the fixed day of every month, the automatic guage examination in a distant place can be executed at a information center without increasing the load of the information center.

Title: High-sensitivity image pickup device
Inventor: MATSUI YOSHIHIKO
IPC: H04N5/335
Filed: 1986-05-12
Abstract: PURPOSE:To obtain an image signal with high sensitivity by applying low shot to extend the light sensing time at each image when an output level of a solid- state image pickup element is lowered at dark state. CONSTITUTION:Since the intensity of light incident on a solid-state image pickup element 3 is weakened at darkness (at night), the level of an image signal outputted from a video amplifier 4 is lowered. When the level of the detected image signal is lowered to 1/2, 1/3, a scanning control circuit 6 changes the scanning time of the solid-state image pickup element 3 at each 2/60sec and each 3/60sec from each 1/60sec in order to increase the output of the solid-state image pickup element 3. Thus, the sensitive time (storage time) at each picture of the image pickup element 3 is extended from 1/60sec to 2/60sec and 3/60 sec and an image signal output with sufficient intensity is obtained from the image pickup element 3.

Filed: 1998-04-16
Abstract: PROBLEM TO BE SOLVED: To reduce a time required for synchronizing the duplicate ATM adaptation layer AAL terminator that converts synchronous transfer mode STM data into an asynchronous transfer mode ATM cell. SOLUTION: A BUS Controller 9 of an active system receiving a cell assembling start request from a CPU 11 outputs a cell processing start signal synchronously with a frame pulse FP to an active system AAL1SAR (cell disassembling/ assembling sub layer) 5 and the active system AAL1SAR 5 receiving this signal starts cell assembling of the active system. Furthermore, the BUS Controller 9 informs a standby system BUS Controller 10 of a timing of the active system cell assembling start via a serial bus.  The standby system BUS Controller 10 receives the timing and starts counting received FPs and when the standby system BUS Controller 10 receives the cell assembling start request after each FP counter of each user connection starts counting the FP, the standby system BUS Controller 10 outputs the cell assembling start signal synchronously with the FP when the count of the FP counter of each user connection reaches 376. An AAL1SAR 6 of the standby system receives the cell assembling start signal to start cell assembling of the standby system.

Abstract: PURPOSE:To obtain an interface circuit whose constitution is simple and circuit area of the whole is small, by supplying an input signal to the collector of the first PNP transistor Tr and obtaining an output signal, to which the input signal is inverted, from the collector of the third NPNTr. CONSTITUTION:A signal output line 9 of the first I<2>L gate 7a is connected to the collector of a PNPTrQ2 and the emitter of an NPNTrQ3; and when the output line 9 is in the low level, no current is flowed to the collector of the NPN TrQ3, and the collector of a TrQ4 is set to the high level, and an output OUT of the second I<2>L gate 7b is set to the low level. When the output line 9 is in the high level, a current is flowed to the collector of the PNPTrQ3, and the TrQ4 is turned on, and the output OUT is set to a high impedance. Thus, the interface circuit between the I<2>L gate 7a and an I<2>L gate 7c different in reference potential from each other is formed without separating respective constituting element from each other.
