Title: Purifying method for gas
Inventor: MOROHASHI TAKASHI
IPC: G01N33/00
Filed: 1980-07-21
Abstract: PURPOSE:To remove impurities in gas, by incorporating a filter packed with fine pieces of vinyl resin or alkyd resin in a duct of sampling part. CONSTITUTION:A sample gas is analyzed by an analyzer 10 of analysis part after removing impurities by a filter of sampling part. Fine pieces of vinyl resin are  packed in a cylindrical vessel made of transparent acrylic resin and said vessel is  incorporated as a filter in a duct of sampling part to perform analysis.

Title: Current-carrying-state monitor
Inventor: OTA MASANORI
IPC: G01R19/00
Filed: 1997-04-16
Abstract: PROBLEM TO BE SOLVED: To make it possible to provide a detector simply by converting the induced current, which is generated by the AC current flowing through an electric apparatur with a current- carrying detector, into an optical signal, detecting the conduction state, monitoring the optical signal with a transmission system and sending the optical signal to a monitoring device with the transmission system. SOLUTION: Electric apparatuses 6a and 6b receive power supply from wirings 52a and 52b of a distribution system 5 and are driven. The induction currents generated by the AC current flowing through the electric apparatuses are converged into the optical signals with current-carrying detectors (2a and 2b), and the current-carrying state is detected. The detected optical signals are transmitted into a monitoring device 3 by a transmitting system 4. The monitoring device 3 converts the optical signals into the electric signals by light-electricity conversion and displays and records the signals. Furthermore, in the transmitting system 4, a common optical fiber 41a is connected to the monitoring device 3. The common optical fiber 41a and the current-carrying detectors 2a and 2b are connected with the optical fibers 42a and 42b.  The optical fibers are connected with connectors 43a and 43b. Since the current- carrying is detected by using the induced current in this way, the detector can be simply set and provided, and the power feeding to the detectors is not required.

IPC: B60G17/015
Filed: 1985-05-09
Abstract: PURPOSE:To prevent the occurrence of hunting in the level control of a car, by detecting a car level with each level-control actuator setting part and, on the basis of this detected car level, setting the order of priority for level control over both front and rear wheels, while constituting a device so as to control the preferential side to be right and left separately but the succeeding side to be common with both sides. CONSTITUTION:Each detected car level of car level detectors 17a-17d installed in body setting parts of each of level-control actuators 1a-1d is inputted into a control circuit 20, and each value is compared with a proper car level lower limit value at this control circuit 20, and when it is below the lower limit value, whether a minimum car level is front wheels or rear wheels is judged. And, for example, if there is a minimum value in front-wheel sides 1a and 1b, these front wheels are prior to rear wheels, and on the basis of each of these detected car levels 17a and 17b, these actuators 1a and 1b are separately adjusted. Next, rear-wheel sides 1c and 1d are adjusted in common. When rear wheels are prior to front wheels, these rear-wheel sides carried out separately but front- wheel sides takes palce in common. With this constitution, level control is prevented from hunting.

Title: Signal switching circuit
Inventor: OGAWA NOBUYUKI
IPC: H03K17/62
Filed: 1982-06-08
Abstract: PURPOSE:To eliminate level shift and to suppress offset, by using a common load being an output terminal as a constant current source in a signal switching circuit comprising transistors (TRs) mainly, and making its current value to about 1/2 of a current value of a constant current source connected to emitters of a TR group. CONSTITUTION:When a TR19 turns on with a switching signal at a switching signal input terminal 27, a TR20 turns off, and when the TR19 is turned on with a signal applied to an input terminal 25, a TR27 and a diode 21 are made conductive. Further, since the TR20 is turned off, a TR18 and a diode 22 are nonconductive and only the signal at the input terminal 25 is fed to an output terminal 29. When the switching signal turns on the TR20 only, the TR18 and the diode 22 are made conductive. Since the TR is turned off, the TR17 and the diode 21 are made conductive and only the signal applied to an input terminal 26 is fed to the output terminal 26. When a current value I2 of a constant current source 23 to which emitters of the TRs19, 20 are connected is I0, a constant current source 24 is used as the load and the current value I1 is taken as I0/2. The level shift arisen at signal switching is prevented by a simple constitution by setting the condition in this way.

Title: Glass for preventing coloration by gamma-ray irradiation

IPC: C03C4/00
Filed: 1989-04-19
Abstract: PURPOSE:To weaken the yellowing degree of CeO2 itself and to provide a glass having a sufficient coloration-preventing effect at a low cost by reducing the amt. of CeO2 to be added to prevent the coloration of the sodalime glass having a specified composition to a specified value. CONSTITUTION:The glass for preventing the coloration by gamma-ray irradiation contains, by weight, 60 to 75% SiO2, 0.5 to 5% Al2O3, 12 to 17% Na2O, 0 to 5% K2O, 1 to 8% CaO, 1 to 6% MgO, 0.1 to 5% B2O3, 0.01 to 1% SO3 and 0.1 to 1% CeO2. The melting atmosphere is adjusted to a reducing state to reduce the CeO2 content to <=1%. CeO2 exists in the molten glass as Ce<4+> and Ce<3+>, and the Ce<3+> is effective in preventing the coloration of glass when irradiated with gamma-rays. However, since CeO2 is supplied from the raw material forms Ce4+, the Ce3+ content is reduced in the oxidable melting atmosphere. When a reducible melting atmosphere is used, the Ce<3+> content is increased, and a sufficient coloration-preventing effect is obtained with a small amt. of CeO2.

Filed: 1993-04-26
Abstract: PURPOSE:To easily protect the connector of a printed board used to cope with the extension or the system change after shipping of a product by attaching an insulating sheet to the surface of the printed board and bending the edge. CONSTITUTION:An insulating sheet 30 is attached to a ROM board 8 with a second spacer 16 between them, and a part corresponding to a recessed cut part 18 of the ROM board 8 is cut and bent down, and then, the whole of the insertion hole of the connector of the printed board is covered with this bent- down part 31 and is protected. Since breadthwise dimensions of the bent-down part 31 of the insulating sheet 30 are made slightly larger than those of the recessed cut part 18 of the ROM board 8, the bent-down part 31 has both side edges of the base end side (fold side) engaged with both side faces of the recessed cut part 18 and is fixed while covering the connection insertion hole of a connector 17 for ROM rewrite. Consequently, spring back is suppressed by both side faces of the recessed cut part 18 even when its occuring in a fold part 32 of the insulating sheet 30.
