Title: Gas sensor
Inventor: MAEDA SHOSAKU
IPC: G01N27/16
Filed: 1985-08-28
Abstract: PURPOSE:To enable the detection of combustible gas containing methane with a quick response, by arranging a thin film heater and a thin film thermosensitive sensor having palladium as oxidizing catalyst on a thin film member provided across the recessed space of a substrate. CONSTITUTION:Insulation films 2, such as SiO2 or Si3N4 are formed on both sides of a silicon substrate 1 and an opening 3 is made in one of the insulation films 2 by photolithography and etching. With this opening as mask, the substrate 1 undergoes an anisotropic etching to form a microbridge 2A of the film 2, on which 2A a thin film of Pd with the thickness of about 100Angstrom  is formed by sputtering and patterned by photolithography and etching to form a Pd lead 4. In the application, a fixed current runs to the lead 4 to raise the temperature up to about 400 deg.C and as a combustible gas such as H2 and CH4 contacts the lead 4, it reacts with oxygen in the air and burns to further raise the temperature of the lead 4, which increases the resistance value. Thus, the presence of combustible gas can be detected by measuring the voltage drop of the lead 4.

Filed: 1987-07-29
Abstract: PURPOSE:To prevent a slack in paper from reaching the front surface of a printing head to cause an error in line feed pitch, by detachably fitting to a paper stacker part a guide plate comprising an elastic plate which has an end part located in the vicinity of and on the paper discharging side of a card holder and lightly energizes the paper against a platen. CONSTITUTION:A paper 2 is fed in a direction A by a pressure roller 3 and a platen 1, is fed through the position of a printing head 4, and is guided by a card holder 5. The paper 5 guided by the card holder 5 and fed toward discharging rollers 8, 9 is lightly pressed downward by a lower end part 10 of a guide plate 7. The paper 2 is fed further outward to collide against a contact point between the discharging rollers 8, 9. At this moment, the leading end of the paper 2 is pressed by the rollers 8, 9, and the paper 2 slackens, but the slack does not reach the part of the paper located at the card holder 5 or the printing head 4 because the paper is pressed by the guide plate 7 in the vicinity of the card holder 5.

CONSTITUTION:When a packet terminal PT1 (X25CR) makes a calling request by a packet (in compliance with the CCITT recommendations X.25), a packet logic multiplexer (IPMX) 3 analyzes an I(X25CR) packet to check the incoming call information speed and checks whether the information speed is within the idle line capacity in a RAm 12, and retrieves the maximum information speed within the idle line capacity among the information speed usable for the packet terminal PT1 registered in advance in the RAM 12, sets the result to the calling information speed in the I(CRR) packet for the transmission. The packet terminal PT1 analyzes the I(CRR) packet, extracts its calling information speed and sets the information speed to the incoming call information speed in the I(X25CR) packet and sends the result.

Title: Sample-and-hold circuit
Inventor: KASAI KIICHIROU
IPC: H03K17/00
Filed: 1992-07-17
Abstract: PURPOSE:To reduce power consumption by holding a constant current source in common. CONSTITUTION:When a constant current source 5-1 is connected to a parallel circuit 4-1 and a current is supplied from the constant current source 5-1 and a 5-2 to the circuit 4-1, a potential applied to a capacitor 3-1 for holding follows to a potential of an input signal to a input terminal 2 and varies, and a tracking state is obtained. Since a current does not flow in a parallel circuit 4-2, a capacitor 3-2 for holding is in an open state and holds a potential immediately before holding, and a holding state is obtained. Therefore, by alternately switching and connecting the circuit 4-1 and 4-2 to the source 5-1 and 5-2 by a switching circuit 6, an input signal is continuously subjected to sample-and-hold, a holding output can be lead out from a selector 7 to an output terminal 8, and power consumption can be reduced as an useless current is not supplied.
