Title: Winding method for pipe
Inventor: KOBAYASHI KAZUTO
IPC: B65H75/38
Filed: 1990-04-19
Abstract: PURPOSE:To prevent a pipe from being deformed into a flat state when it is wound by deforming the pipe into a flat state before winding the pipe on a winding drum so that the pipe is formed into a true round shape by the deformation generated when the pipe is wound on the winding drum. CONSTITUTION:A pipe P passes between caliper rollers 21 of a flattening device 20 before the pipe P is wound on a winding drum 10, thus the pipe P is flattened in the vertical direction. When a driving drum 30 presses the pipe P to the winding drum 10, the rotation of the driving drum 30 is transferred to the winding drum 10 via the pipe P, and the winding drum 10 is rotated. A sheet-shaped cushion member 40 is wound on the outside of the wound pipe P. The pipe P is wound on the outside of the cushion member 40. The pipe P is wound in a line along the opposite direction to the winding direction of the previously wound pipe P along the axial direction of the winding drum 10.

Title: Cordless telephone system
IPC: H04W84/10
Filed: 1992-03-31
Abstract: PURPOSE:To reduce the calling loss probability of a slave unit installed in a place where the jamming of communication such as noise or the like is easy to happen by counting a counter and retransmitting for the number of times corresponding to the count of the counter at the time of transmitting the next data to this slave unit when a confirmation signal is not transmitted back from the slave unit at the time of transmission from the side of a base unit to the slave unit. CONSTITUTION:For the cordless telephone system, when an incoming call comes to a telephone line L stored in a master set 1, a CPU 5 detects this incoming call through an incoming call detecting circuit 12, transmits call terminating data through a radio channel constituted of a radio transmitting/receiving part 27 and an antenna a1 to a slave unit 30A, and also receives the confirmation signal to indicate the reception of the call terminating data to be transmitted back from the slave set 30A. But, when the confirmation signal is not received within prescribed time, the error counter of the above-mentioned slave unit is counted one. This value of the error counter stipulates the number of the times of retransmission when transmitting the call terminating data to the above-mentioned slave unit at the time of the next incoming call.

Title: Bubble removing device
Inventor: MATSUI KUNIO
IPC: F16L55/07
Filed: 1979-08-16
Abstract: PURPOSE: To remove bubbles surely with simple constitution by connecting a bubble path on the inner side of the turning radius of a flow passage which is so arranged as to flow liquid spirally, near the outlet terminal of said passage.  
     CONSTITUTION: When the liquid contg. bubbles is flowed into a spiral flow passage 1 through an inflow port 5, the liquid flows at a high speed in the spiral flow passage 1 and shifts to the outflow port 6 side. At this time, the bubbles mixed in the liquid are small in specific gravity; therefore, while the liquid flows in the flow passage 1, the bubbles flow along the inner side of the flow passage 1 by centrifugal force, pass through the bubble extraction port 2 provided near the terminal of the flow passage 1 and are automatically separated from the liquid in the flow passage 1. The bubbles removed from the flow passage 1 pass through the bubble path 3 branched from the flow passage 1 and are discharged to the outside through a valve 4. The liquid having been removed of the bubbles is taken out from the outflow port 6 of the flow passage 1.

Abstract: PURPOSE:To provide more convenient way of using the captioned device in a finisher of a copying machine, etc., by controlling the feed of a recording material by a feeding means in responce to an output from a detecting means for detecting the presence of the recording material within a housing part. CONSTITUTION:The microcomputer 500 of a finisher control part changes over a changeover guide on a feeding passage such that, when an edit signal AIS is inputted, it takes out any bin in the order specified by a key 101 and indicated on an indicator 102 every two bins in a collator mode and every bin in a non- collator mode and sends it to a housing tray. Then, when a staple signal STS is set, a set of copies is stapled and discharged one by one, and thus feeding, stapling and discharging are repeated according to the sensor signal PES for detecting the presence of a paper within the housing tray. Further, when the STS is not set, the microcomputer waits until the PES signal becomes H. In such a way, it is made possible to prevent the damage of a document, etc., and to make copies throwaway, allowing a copying operation for a large quantity of copies to be performed.

Namely at the time when the static pressure of the communication pipe 11 inside is low at the low load and low revolution time of the engine 2, for instance, the control valve 15 is controlled so as to be closed. The exhaust gas is thus held up inside the communication pipe 11 and reburnt.

Title: Pin, method for erecting pin and pin erecting board
Inventor: MATSUURA TETSUJI
IPC: H05K3/40
Filed: 1999-04-13
Abstract: PROBLEM TO BE SOLVED: To provide a pin which can be erected in a specified direction in a pin erecting jig, a method for erecting a pin by which a pin can be erected in a specified direction in a pin erecting jig, and a pin erecting board in which a pin can be erected easily and which can be manufactured at a low cost. SOLUTION: A pin 1 is provided with an engaging part 2 and a tip end part 3 and a base-side end part 4, which are extended in the mutually opposite direction from the engaged part 2. The diameter of the engaged part 2 is larger than that of the tip end part 3 and a maximum size of the base-side tip end part 3. Therefore, when the pin 1 is erected on a pin erecting jig 11, it is inserted into the through-hole of the pin erecting jig 11 from the side of the tip end part 3. Since the diameter of the tip end part 3 is smaller than of a tip-end insersion hole 12, the tip end part 3 is inserted loosely into the hole 12 and is erected therein. Since the maximum size of the base-side tip end part 4 of the pin 1 is larger than the diameter of the hole 12, the base-side tip end part 4 cannot be inserted into the hole 12.  Thus, the side of the tip end part 3 is inserted easily and correctly into the hole 12, and the pin 1 can be erected in the pin erecting jig 11.

Title: R-wave detector
Inventor: ENDO TOSHIYUKI
IPC: A61B5/352
Filed: 1987-04-28
Abstract: PURPOSE:To detect the signal synchronizing to an R-wave with high accuracy, by calculating the change rate of the sampling data coinciding in a phase among sampling data read at a predetermined cycle. CONSTITUTION:An electrocardiographic signal SE is outputted from an electrocardiograph 10 and converted to a digital signal SED by an A/D converter 14. A CPU 16 outputs a timing signal ST to the A/D converter 14 at a definite sampling cycle to read the digital signal SED and calculates the change rate Si of sampling data. The change rate Si is calculated from the signal values f(i), f(i+37) of two digital signals. Since two signal values coincide in the phase to the cycle T thereof with each other, the change rate Si is not affected by the cyclical noise due to a commercial AC power source. Further, the synchronous signal SED determined by the change rate Si is made always synchronous to an R-wave with high accuracy. Therefore accurate automatic diagnosis is attained.
