Title: Developing device for electrophotographic recorder
Inventor: KITAJIMA YUJI
IPC: G03G15/08
Filed: 1989-03-24
Abstract: PURPOSE:To securely prevent toner from leaking on both sides of a developing roller by extending a sealing body toward the position where the developing roller is in contact with a layer thining roller, and pressing the extended part against the periphery of the developing roller. CONSTITUTION:The sealing body 42 is provided on both sides of a replenishment roller 36. The sealing body 42 is produced from, for example, foamed polyester, and its one side is attached to the side plate 21a of a casing 21 by the use of, for example, double-sided tape. The sealing body is formed into a teardrop by extending the body toward the position where the developing roller 26 is in contact with the layer thining roller 29, and the extended part 42a is pressed against the periphery of the developing roller 26. Thus, toner is prevented from leaking on both the sides of the developing roller 26 by pressing the sealing body 42 against the developing roller 26.

Title: Method for forming elliptic shape, rotating ellipsoid, hyperbolic shape, rotating hyperboloid, and parabolic shape
Inventor: HOSHINA MASATAKE
IPC: B23Q15/00
Filed: 1989-03-24
Abstract: PURPOSE:To accurately form an object having an elliptic, hyperbolic, or parabolic outline or its rotating body under simple control by successively and straight moving a cutting tool or the like on an object to be worked to shave off the object. CONSTITUTION:Two fixed points F1, F2 are determined on the object 1 to be worked and a circle with a radius longer than the distance between the points F1, F2 is plotted around the point F1. An optional point An is plotted on the circle and the object 1 is cut out by the cutting tool or the like along the vertical bisector of the segment F2An. A similar circle is plotted around the point F2 and the object 1 is cut out by the similar method to form an elliptic shape. When the object 1 is cut out while rotating the object around the rotation axis shown by a straight line F1F2, a rotating ellipsoid can be formed. In addition, objects having hyperbolic and parabolic outlines and their rotating bodies can be formed by similar methods. Consequently, cutting control can be simply and easily executed.

Title: High-speed connection setting method for atm communication network
Inventor: TSUCHIDA MITSURU
IPC: H04L12/28
Filed: 1996-03-28
Abstract: PROBLEM TO BE SOLVED: To shorten the time from the generation of a data transfer request on a terminal device to the start of data transfer in the ATM communication network. SOLUTION: An ATM switching device 1a is triggered by the reception of a VPC setting indication command from a network management device and starts VPC setting operation with an ATM switching device 1d meeting VPC setting conditions specified with the VPC setting indication command. If data which should be sent out of a terminal device 3a to a terminal device 3g is generated after the VPC setting, the terminal device 3a sends a call signal 61 out to the ATM switching device 1a, but the ATM switching device 1a having received the call signal 61 sends a VCC setting request signal 65d out to the ATM switching device 1d since a connection link directly reaching the ATM switching device 1d is generated by the VCP setting. Connection setting can be made speedy since the ATM switching device 1c can be passed through.

Title: Vertical magnetic head
Inventor: NAKAMURA KAZUO
IPC: G11B5/265
Filed: 1984-04-13
Abstract: PURPOSE:To produce easily a composite magnetic head which has a sufficiently small space between a main magnetic pole and erasion magnetic poles and is free from the mutual interference between both magnetic poles, by holding the main magnetic pole between two substrates with erasion magnetic poles set in the grooves formed at both sides of the main magnetic pole. CONSTITUTION:A nonmagnetic substance block 18 is joined to a magnetic substance block 19 of high permeability to obtain a substrate 17. A main magnetic pole 26 is held between the substrate 17 and a substrate 27 having the same structure as the substrate 17. Then erasion magnetic poles 25 made of magnetic films of high permeability are set on the bottom surfaces of two grooves 23 formed in parallel to each other at both sides of the pole 26. The signal windings are provided to the magnetic substance parts of both substrates 17 and 27. In such a constitution, the original record signal is recorded with the pole 26 in a recording mode and at the same time recorded at both sides of the pole 26 by the poles 25 at different azimuth angles. In a reproduction mode the levels of signals reproduced by the poles 25 can be reduced enough. Thus it is possible to obtain a composite head which has a sufficiently small space between poles 26 and 25 and is free from the mutual interference between both poles.

Title: Signal generating circuit
Inventor: KATAGIRI KOUICHI
IPC: H04N7/173
Filed: 1984-04-13
Abstract: PURPOSE:To attain always a display clock signal and a horizontal synchronizing signal in certain phase relations by detecting the point where the phase difference between a chrominance subcarrier and the display clock signal is a prescribed value and controlling the operation of a synchronizing signal generator by this detection output. CONSTITUTION:When a power source is turned on, a J-K F/F14 is set to the clear state, and a signal SQ is supplied to the reset terminal of a synchronizing signal generating circuit 2' from an output terminal Q. The signal SQ sets a J-K F/F18 to the clear state to inhibit the output of display clocks CLK from the output terminal. When the operation of a PLL circuit consisting of an oscillator 6, a phase comparator 5, etc. is stabilized, output ''1'' is obtained from a timer circuit 11, and thereby, the output SQ of the J-K F/F14 goes to high level ''1'' to start the operation of the synchronizing signal generating circuit 2'. Simultaneously, the clear state of the J-K F/F18 is released by the signal SQ, and the display clock signal CLK of 5.727MHz is outputted from the output terminal Q.

Title: Water heating device
Inventor: TAKAHASHI YUTAKA
IPC: F24D17/00
Filed: 1983-04-26
Abstract: PURPOSE:To enable to obtain high temperature hot water with comparatively small electric power input by a method wherein the hot water stored at low temperature is heated-up by instantaneous heating. CONSTITUTION:When hot water supply is intended, a control unit 17 is operated so as to start a water transfer pump 9 and to turn ON an on-off valve 10. The hot water in a hot water storage chamber 23 is heated at an instantaneous heat exchanger 28 and past through the on-off valve 10 and a vacuum breaking valve 11 and flowed outside from an outflowing port 16. A diaphragm valve 13 is closed by the pressure rise in the water passage part of the vacuum breaking valve 11. A bypath 12 is completely closed, resulting in flowing cold water from a cistern into the hot water storage chamber 23. Next, when heating by circulation is intended, the on-off valve 10 is turned OFF. Because of the lowering of the temperature of the hot water in the hot water storage chamber 23 due to the inflowing of cold water during hot water supply, the signal of a hot water storage chamber hot water temperature sensor 18 brings the control unit 17 into actuation so as to start the water transfer pump 9 and energize a heat generating body 20. Because the valve closing force of the diaphragm valve 13 becomes very small due to the vacuum breaking valve 11 being open, the hot water in the hot water storage chamber 23 is heated at the instantaneous heat exchanger 28 and past through the bypath 12 and circulated from the suction port of the water transfer pump 9 to the hot water storage chamber 23.
