Title: Manufacture of pipe having irregular-shaped cross section
Inventor: YANAIDA KAZUO
IPC: B29D23/00
Filed: 1988-01-13
Abstract: PURPOSE:To easily manufacture a pipe having an irregular-shaped cross section and the same cross section as that of a male mold at the inner surface thereof, by inserting said male mold into said pipe made of thermoplastics, and heating said pipe up to not less than the softening temperature thereby to render the interior of said pipe at the negative pressure. CONSTITUTION:The entirety of a pipe P into which a male mold D having a desired cross section is inserted is heated up to not less than the softening temperature, so that the interior of the pipe P is rendered at the negative pressure. Consequently, the inner surface of the pipe P is deformed to be tightly adhered to an outer periphery of the male mold D. Therefore, the cross section of a pipe P1 after deformation is correctly a copy of the cross section of the male mold D. When the thus-deformed pipe P1 is cooled as it is and solidified, and the male mold D is pulled out, a pipe P2 having the desired irregular-shaped cross section can be obtained. The material for the pipe P is stable thermoplastics such as polyethylene, polypropylene etc., and it is particularly preferable to have a low melting point.

Title: Data transmission method
Inventor: IGARI HIDEO
IPC: H04L12/701
Filed: 1999-01-13
Abstract: PROBLEM TO BE SOLVED: To update entry before movement by means of a minimum number of regenerated packets in a short time by limiting unwanted regeneration of the regenerated packets in a mobile communication network. SOLUTION: A moving node MH transmits a control packet to a home router HR immediately after its movement. A router R1 receives this control packet. The router R1 transfers the control packet to a succeeding router R2 on a path toward the home router HR, and also generates a regenerated packet resulting from copying the control packet and transfers it to routers R10, R11 adjacent to the router R1. In this case, the router R1 does not transfer the packet to routers R5, R4 that are located in an area, to which the moving node moves at a lower probability on the basis of their geographical conditions.

Abstract: PURPOSE: To eliminate unnaturalness of the compressed reproduction sounds by performing changing over of the writing and reading of a plurality of delay devices in association to the output of the time when the head portion of each syllable of the reproduction input signal is detected.  
     CONSTITUTION: When the reproduction signal from terminal 1 enters at time intervals of sections T 1  thru T 3 , a detection pulse Pd generates from a peak detection circuit 15 in the position of the head of each syllable and after T/2 thereof, an output pulse P 3  is generated from a counter 16. When the pulse P 3  is supplied  via OR 19 to an FF 20, a switching signal Tg and anti Tg are generated and  between the high levels thereof, the signal S 1  of the portion of the head of that  syllable in the section T 1  and the same signal S 2  in the segment T 2  are respectively  written in delay devices 3,4 by changeover circuits 2,5 and switch circuit 11. At the  same time, the signal S 1  having been written previously is subsequently read out  from the head of the syllable from the device 3 but in the segment T 2  reading out  all of the signal S 1  is not possible. However, missing of important portions will not  occur. Hence, the unnaturalness of the compressed reproduction sounds may be  perfectly eliminated.

Title: Phase synchronizing circuit
Inventor: KATOU KEIICHI
IPC: H03L7/093
Filed: 1980-01-22
Abstract: PURPOSE:To ensure an apparent linearization characteristics for both the output frequency and the control voltage of a voltage controlling oscillator, by applying an appropriate feedback to a low-band pass filter by the signal obtained by differentiating the control voltage. CONSTITUTION:The phase difference detector 1 sends the leading pulse P1 or lagging pulse P2 to the transistor TRQ1 or Q3 according to the difference of phase between the input signal (a) and the output (f) of the voltage controlling oscillator 3. With transmission of the pulse P1 from the detector 1, the current I1 supplied from the TRQ7 of the current source is charged by the capacitor C1 through the TRQ2 and while the P1 is generated. As a result, the control voltage VC increases to decrease the frequency of the output (f) of the oscillator 3, thus controlling the signal to be in-phase with the signal (a). When the voltage VC has a fluctuation in the direction of increment by the feedback capacitor C2, the base voltage of the TRQ7 increases. Thus the quantity of the current I1 decreases.
