Title: Access-channel-conflict preventing method
Inventor: HANAZAWA TETSUO
IPC: H04W72/12
Filed: 1979-04-02
Abstract: PURPOSE:To lessen probability that access channels conflict with each other in the system where subordinate stations attain access to a key station by using the same channel, by grouping subordinate stations and by sending 1st access signals to every group. CONSTITUTION:Signal 11 is sent from a key station to each subordinate station all the the time. Signal 11 consists of frame syncrhonizing signal 12 showing the start, time zone 13 showing the grouping of subordinate stations, and codes 14 and 15 showing subordinate stations accessibility. Here, when subordinate station A of number 1234 and subordinate station B of number 5678 attain access simultaneously, 1st access transmission signals 16 and 17 whose 1st digits showing subordinate station groups of 4 and 8 are sent out from stations A and B at time C14 and C18 respectively following signal 12 from the key station. Receiving them as signals 18 and 19, the key station sends codes 14 and 15 with the 1st digits of 4 and 8 showing that the corresponding subordinate stations 4 and 8 can attain access. By decoding them, the subordinate stations receives remaining numbers of subordinate stations as signals 23 and 24 at the end of the code reception, so that access of stations A and B will be accepted.

Title: Call transfer system for trunk line attendant board
Inventor: NISHIMURA KOJI
IPC: H04M3/54
Filed: 1992-02-27
Abstract: PURPOSE:To implement freely 'immediate holding of transfer call' and 'transfer of transfer call' by providing two paths for voice channels and holding one path so as to an outgoing call from the other path to the transfer destination. CONSTITUTION:A multiplexer/demultiplexer MDX13 of a trunk line attendant board 11 sends/receives voice signals of two paths for channels V1, V2. A control circuit CTL15 makes dialing from other path while holding voice talking of one path to make talking with a transfer destination extension and sends a connection request between the holding call and the transfer destination to a private branch of exchange after the transfer destination is decided. When an incoming call comes from the private branch of exchange via a line 18, a changeover switch SW17 connects the channel V1 to a handset HS12. When the operator makes holding operation and dials a transfer destination, the SW17 is switched and a holding tone is sent to the channel V1 and the HS12 is connected to the channel V2 to attain the talking with the extension of the transfer destination. Thus, other channel than that for an external line is used to operate a transfer call freely.

IPC: G05D3/12
Filed: 1988-02-23
Abstract: PURPOSE:To make positioning faster in speed and higher in accuracy by adding a feed-forward quantity based on the polarities of a speed command quantity and the rotating speed of a motor to a torque command quantity and a feed- forward quantity based on a position deviating quantity and the polarity of the rotating speed of the motor to another torque command quantity. CONSTITUTION:A rough positioning process in which a feed-forward quantity Tc based on the polarity of a speed command value X'r and the polarity of the rotating speed theta 'm of a motor is added to a torque command quantity Tr and fine positioning process in which a positional deviation quantity Er and a feed-forward quantity Tc based on the characteristic of the rotating speed theta 'm of a motor is added to another torque command value Tr, are performed. Thus the influence of the dynamical friction force Fm received by a controlled system 10 while it moves is compensated by the feed-forward quantity Tc in the rough positioning process and the compensation of the influ ence of the stational friction force Fs received by the controlled system when the system is stationary and to raise the gain of a position loop is fed forward. Therefore, high-speed positioning is realized with high accuracy.

IPC: A61M5/315
Filed: 1989-02-22
Abstract: PURPOSE:To use without hindrance even an inexpensive material poor in compression permanent strain by providing a gasket receiving part having an inner diameter larger than that of the internal passage of an outer cylindrical member to a part of said internal passage and receiving the gasket sliding along the inner wall surface of said passage in a close contact state in said receiving part during a period before use. CONSTITUTION:A gasket receiving part 2d formed so as to have a diameter larger by 0.1mm or more than the internal passage 2c of an outer cylindrical member 2 is provided in the vicinity of the base end of the outer cylindrical member 2 so as to concentrically communicate with the internal passage 2c. The gasket 3 is received in the gasket receiving part 2d when a syringe 1 is in an unused state. The outer diameter of the peak part 3a of the gasket 3 may has a size closely brought into contact with the inner wall surface of the internal passage 2c to be capable of holding sufficient airtightness and liquid tightness. By this method, since a state such that the pressure in the direction reducing the diameter of the gasket is not severely applied to the peripheral edge part of the gasket is held, a plastic material relatively inferior to compression permanent strain and considered to be unsuitable for a gasket sufficiently holds airtightness and liquidtightness during use.

CONSTITUTION:When an upstream side partition valve 7a is closed, a downstream side partition valve 7b is opened, and a movable relay tube 6 is advanced (to the left), a bellows-like expandible tube 4 is extended to suck up soil and sand in a soil-charging box 1 into the tube 4. Also, when the tube 7b is closed, the tube 7a is opened, and the tube 6 is retracted (to the right), soil and sand is moved from the tube 4 into the tube 6, and the same operations are repeated thereafter. The tube 4 is used for the upstream side, and the outer periphery of the tube 4 is supported on a movable ring M. On the downstream side, an inflexible fitting slide tube 6b is provided. Sucking function on the upstream side of the tube can thus be raised, and the occurrence of buckling of the tube on the downstream side can be prevented.

Title: Format conversion system
Inventor: HIRANO KENGO
IPC: H04B10/272
Filed: 1996-02-28
Abstract: PROBLEM TO BE SOLVED: To reduce propagation delay time by decreasing the time required for format conversion between an optical signal frame and an in-equipment signal frame. SOLUTION: A branching device 27 divides an in-equipment signal for a burst period into a first half and a latter half and provides an output of the first half to a data memory 21 and provides an output of the latter half to a data memory 22. Address selectors 29, 30 apply a write address to one of the memories corresponding to an output of the branching device 27 and apply a read address to the other memory. Thus, while the one memory makes write, the other memory conducts read so as to reduce the read time actually.

Title: Tool for opening and closing door
Inventor: FUJITA KEIICHI
IPC: B62D65/00
Filed: 1997-02-25
Abstract: PROBLEM TO BE SOLVED: To suppress a malfunction of a sensor by providing a rotary actuator oscillating a sensor case between a working location where a detection window is situated at a part to be detected of a door and a retreating location where the detection window is isolated from the part to be detected of the door and is turned obliquely upward on the rear side on a tool main body. SOLUTION: After a door is caught by a door holding bar 4, a sensor case 3 is oscillated from a working location to a saving location by a rotary actuator. Because the sensor case 3 occupying at the retreating location is remarkably isolated from the glass storage groove of the door and the axis of the sensor case 3 is inclined backward to a vertical axis, a detection window is opened obliquely upward on the rear side. As a result, a malfunction of the sensor caused by coating mist can be suppressed as much as possible since coating mist during a coating work becomes difficult to enter from the detection window.
