Inventor: MURAKAMI KAZUYUKI
IPC: D01F9/145
Filed: 1989-11-28
Abstract: PURPOSE:To improve the stability in spinning by subjecting an asphaltene-free oily or tarry substance to two-step heat treatment under specified conditions. CONSTITUTION:An oily or tarry substance which comprises a fraction having a boiling point of 500-550 deg.C under atmospheric pressure and obtained by vacuum distillation of a heavy residual oil formed as a by-product in catalytic cracking of petroleum, which contains an n-heptanes-soluble aromatic matter and resinous material as principal components, and which does not contain an n-heptane- insoluble component comprising an asphaltene is heat-treated at 380-460 deg.C under a reduced pressure while blowing an inert gas therein until an optically anisotropic phase amounts to 5-20%. The optically anisotropic phase is then separated and removed. The obtained pitch is heat-treated at 380-460 deg.C until the optically anisotropic phase amounts to 20-70%, and the optically anisotropic phase is then separated and collected, thus giving an optically anisotropic pitch having a longitudinal relaxation time of 2,000-3,000msec as measured by the solid-state broad line <1>H-NMR and a rate of change in magnetic field orientation of 0.20 to 0.50 as measured by the pyrene-added high-temperature <13>C-NMR.

Title: Pressure forming die for superplastic alloy
Inventor: KANEKO NOBUO
IPC: B21D37/20
Filed: 1987-12-08
Abstract: PURPOSE:Not to copy an air vent part for pressure forming on the surface of a plasticized product and to eliminate the need for surface correction after forming by making up a die required for pressure forming a superplastic alloy plate out of >=2 split dies and considering a clearance between joined surfaces of the split dies an air vent of specified dimensions. CONSTITUTION:After the plate 2 of superplastic alloy such as Zn-22% Al alloy, etc., is heated by preheating plates 1a, 1b at superplastic temperatures 250-270 deg.C, two split dies, namely, a bottom plate 8 and a front plate 9 are positioned by a knock pin 10 and then the alloy plate is set between a die (copying die) 3 locked and formed by a locking bolt 11 and a clamping frame 4. In this case, the clearance between the bottom plate 8 and the front plate 9 makes an air vent 12 having a clearance 0.2-0.005mm. High pressure air is pressed in from an air press-in hole 5 fitted in a clamping frame 4, the alloy plate 2 is deformed superplastically by pressure forming, pressed to the die 3 to form a work 6 on which the internal shape of the die 3 is copied. In this process, the air between the die 3 and the alloy plate 2 is discharged from the air vent 12 of fine clearance, but since the clearance of the air vent 12 is so small that recess parts are not copied on the work 6, therefore, the surface need not be corrected.

Title: Multiplex transmission system
Inventor: ICHII EIJI
IPC: H04Q9/00
Filed: 1992-11-18
Abstract: PURPOSE:To surely detect a faulty node and to improve the reliability of ACK management by revising renewal logic of a registration means when other node interrupts frame re-transmission of one node for transmission. CONSTITUTION:During re-transmission of a frame by an air-conditioner unit multiplex node 12, a frame of a door FR multiplex node 15 makes interruption and a door FL multiplex node 14 returns an ACK signal. Then each node except the node 12 registers a signal to an ACK table of its own station as an object of ACK management. However, the node 12 disregards it and the ACK table is not revised against the return of the signal by the node 14. When the re- transmission is finished, the node detects that the signal is not returned continuously four times and the revision of the table is ensured. Thus, the detection of a faulty node is ensured and the reliability of ACK management is improved.

Title: Differential-pressure measuring apparatus with clogging-diagnosing mechanism of connecting pipe
Inventor: TOYODA SHOJIRO
IPC: G01L13/00
Filed: 1994-12-13
Abstract: PURPOSE: To obtain a differential-pressure measuring apparatus by which the clogging of a connecting pipe can be detected, whose reliability is high and whose maintenance and inspection operation is easy by a method wherein the output signal of the differential-pressure measuring apparatus is changed over from a measuring signal to a check signal so as to be output and a change in a differential pressure based on the check signal is compared with a reference value. CONSTITUTION: When the clogging of a connecting pipe 7 is to be diagnosed, a check-signal transmission means 11 changes over the output signal of a flowmeter body 6 from a measuring signal to a check signal so as to be output. A diagnosis means 12 detects a change in a differential pressure based on the check signal, it compares the change with a prescribed reference value, it detects the clogging state of the connecting pipe 7, and it outputs a detection signal. When the connecting pipe 7 is clogged both on the side of a high pressure and on the side of a pressure, the differential pressure before and after an orifice 8 is not transmitted to the flowmeter body 6. When one side of the connecting pipe 7 is clogged, the change amount of the pressure difference transmitted to the flowmeter body 6 becomes smaller than that in a normal operation. When the connecting pipe 7 is going to be clogged, the response of an output is depayed or the change amount becomes small. Consequently, when the state of a response which is output to the flowmeter body 6 is compared with that in the normal operation, it is possible to detect whether the connecting pipe 7 is normal or not.

Title: Method for adjusting electromotive force of gas sensor element
Inventor: KANEYASU KAZUNARI
IPC: G01N27/406
Filed: 1993-12-10
Abstract: PURPOSE:To make it possible to adjust the reference electromotive force of a gas sensor element readily by connecting a DC stabilized power supply between a working electrode and a reference electrode, and applying the specified voltage. CONSTITUTION:The (-)terminal of a DC stabilized power supply 11 is connected to a working electrode layer 7 of a solid electrolyte gas sensor element 10. The (+)terminal is connected to a reference electrode layer 9. When the constant voltage is applied, the current based on the difference between the electromotive force of the element 10 and the applied voltage flows. That is to say, when the potential of the electrode layer 7 is higher than the potential of the terminal of the power supply 11, the current flows from the electrode layer 7 to the power supply 11. In the reverse case, the current flows from the power supply 11 to the electrode layer 7. As a result, movable ions are moved in a solid electrolyte layer 5 of the element, and the activity change of the movable ions at the interface of the electrode layer 7 and the electrolyte layer 5 is generated. Therefore, the electromotive force of the element 10 itself is changed into the direction offsetting the difference with the applied voltage and substantially agrees with the applied voltage value from the power supply. Thus, the reference electromotive force having the constant correlation with the voltage can be freely adjusted by applying the specified voltage from the power supply 11.

For example, since a number of '01(2345)6789' whose lower 4-digits are coincident with '6789' is stored in the memory means, the number is displayed on a display means 20. The caller observes the display and uses a dial button 22 to select the dialed telephone number.
