Title: Stopper for captire or hose-storage unit through the application of pulley
Inventor: AOYANAGI KEIICHI
IPC: B65H59/16
Filed: 1981-05-25
Abstract: PURPOSE:To easily store or pull out a captire or hose by installing a stopper provided with a groove into which the hose or the like is fitted and by stopping the movement of the hose or the like, changing the layout of the grooved stopper from vertical to horizontal. CONSTITUTION:A hose or captire code pulled out of a pulley is fitted into the groove of a stopper hanging below the pulley. When the pressure is released, the hose or the like pulls up the grooves stopper together and changes the layout of the stopper from vertical to horizontal, which generates friction between the hose and the stopper, thereby halting the movement of the hose or the like. When stored, the hose or the like is slightly pulled out and put out of the groove. When the pulling force is slackened, the hose or the like is stored by the rotation of the pulley. Therefore, the hose or the like can be stopped without fail by simply handling the hose. In addition to the easy handling, the stopper is simple in construcion and hence minimizes operational failure.

Title: Automatic hot water feeding bath device
Inventor: KUBOYA MASAKANE
IPC: F24H1/46
Filed: 1992-02-28
Abstract: PURPOSE:To prevent hot water from overflowing from a bath tub even when a set water level is at the maximum water level in a bath tub by a method wherein a volume ranging from a remaining water to a set water level is calculated, the hot water is fed into the bath tub, the set water level is compared with a set water level after turning on a power supply and the feeding of the hot water into the bath tub is stopped even when a desired result of calculation is attained. CONSTITUTION:A remaining water H1 in a bath tub is detected, an amount of water required for getting a set water level H2 is calculated and then a water level H3 after feeding of hot water into the bath tub is detected. In the case that a relation of H3>=H2 is not attained, but H2 is higher than an initial automatic set water level H4 after turning-on a power supply, the fact that a relation of (H3-H1)X2<(H2-H1) is detected. If so, it is judged that the set water level H2 is higher than the maximum height in the bath tub and then the hot water feeding is completed. With such an arrangement, even if the set water level is higher than the maximum water level in the bath tub, the hot water does not overflow from the bath tub.

Title: Line switching method for radio relaying system
Inventor: TAKAHASHI YASUO
IPC: H04B1/74
Filed: 1990-03-28
Abstract: PURPOSE:To prevent a switching time from being increased even when the number of switching blocks to be switched is increased by connecting all standby lines at every switching block in cascade at all times. CONSTITUTION:Standby line connector switches 21, 22 are always activated to connect all standby lines 171-173 for switching blocks 1-3 in cascade. For example, when the fault of an active line 20 is detected at the reception end of the switching block 3, a line switching controller (AL) 25 receiving a switching signal selects a sending end parallel switch (TXSW) 7 to send the signal of the active line 20 to the standby line 172. A standby line pilot detector 16 does not detect a host standby line pilot and is selected to receive and output the signal of the active line 20 sent to a receiving end changing-over switch (RXSW) 13 and the standby lines 172, 173. Thus, the switching time is almost the same even when some standby lines in a switching block are connected in cascade and the switching of the system is attained in the switching time of one block.

Filed: 1987-03-31
Abstract: PURPOSE:To increase a processing speed by dividing a received signal by BPFs into plural frequency bands, performing A/D conversion at sampling intervals matching with necessary frequency resolution, and inputting A/D conversion outputs to a memory. CONSTITUTION:A received signal which is reflected by the surface of the sea and received by a receiver is distributed into four by a power distributor 1. Then output digital signals of the distributor 1 are divided by the 1st-4th BPFs 2-5 into the four frequency bands. Consequently, the output digital signals of 1st-4th A/D converters 6-9 have necessary frequency resolution by the bands and data rates matching with the band widths. Then the outputs of the converters 6-9 are multiplexed and stored in the input memory 10. Then the data stored in the memory 10 is transferred, band by band, to a Doppler filter 11 to generate filter banks by Fourier transformation, thus dividing an observation area. Consequently, the processing speed is increased.

Title: Production of glass sleeve for connecting optical fiber
Inventor: UCHIUMI ATSUSHI
IPC: C03B23/08
Filed: 1979-06-22
Abstract: PURPOSE:To achieve the improvement in the working accuracy of the inside circumferential surface of the sleeve by inserting a fire-resisting columnar body into a glass pipe, heating the glass pipe to let it make close contact with the outside circumference of the columnar body and reduce its diameter, removing the columnar body after cooling and drawing the glass pipe under heating. CONSTITUTION:A carbon rod 2 which is of a rhombic shape in section and has been so polished as to be tapered in the lengthwise direction is inserted into a glass pipe 1 and the glass pipe 1 is heated from its outside by a burner of an oxyhydrogen flame or the like, whereby it is reduced of its diameter to make close contact with the outside circumference of the carbon rod 2. When this composite 3 is cooled and the carbon rod 2 is removed, the hole of a rhombic shape larger than the outside diameter of the glass fiber is formed in the glass pipe 11. Next, the glass pipe 11 is so drawn under heating that its hole becomes of the size corresponding to the outside diameter of the optical fiber. Here, even if the carbon rod of high purity is heated to the glass softening temperature or more, it does not change its shape and since it permits easy polishing of high accuracy, the glass sleeve 13 for optical fiber connection which is free from any unevenness on the inside circumferential surface and has been worked to high accuracy is obtained.

IPC: C10G1/06
Filed: 1993-04-06
Abstract: PURPOSE:To provide a coal liquefaction process comprising using a new substitute for a catalyst which can be produced inexpensively and has an excellent function of promoting a coal liquefaction reaction. CONSTITUTION:This liquefaction process comprises adding fine particles of a metal hydride prepared by allowing a hydrogen storage alloy to absorb hydrogen to a coal slurry prepared by mixing feed coal with a solvent under conditions represented by the region above the equilibrium decomposition pressure curve of the metal hydride, mixing the obtained mixture to form a coal slurry and subjecting the resulting slurry to a coal liquefaction reaction under high-temperature and high-pressure conditions represented by the region under the above curve in a reducing atmosphere. Because the hydrogen released from the metal hydride is in the state of radicals, is very highly reactive and can contribute to a liquefaction reaction, the efficiency of a liquefaction reaction can be improved as compared with that attained when a conventional catalyst is used, and the yields of a desired liquefied oil can be increased.
