摘要:
In radio communication system in which single frequency simultaneous transmission and reception is performed, a speech audio signal is divided by a predetermined time interval. A transmission time and a reception time are allotted in the predetermined time. A time-compressed signal is transmitted during the transmission time, and a time-compressed signal transmitted from other transceiver is received during the reception time and it is decompressed to the original length. The transmission time and the reception time are alternately repeated to transmit and receive the audio signals substantially simultaneously by a single frequency, and the audio signal is reproduced from the received signal. When communication with a telephone set is to be established, a DTMF signal is used as a dialing signal to call the telephone set from the transceiver. The DTMF signal is time-compressed and then transmitted along with the speech signal. A transmission timing of the DTMF signal is controlled, and the generated DTMF signal is temporarily stored in a memory. When the transmission of the DTMF signal can be completed before the transmission time is switched to the reception time is determined, and if it can, the DTMF signal is read from the memory and transmitted.

A tanker which can reliably prevent the outflow of cargo oil from cargo oil tank sections (1, 2, 105, 106) in the ship body in the event of damage or injury to an outer plate (8, 9) of the ship body has a double-sided hull construction (4, 104) arranged on opposite sides of each cargo oil tank in the ship's body and a mid-height deck (3, 118) arranged to divide each cargo oil tank into an upper cargo oil tank (2, 106) and a lower cargo oil tank (1, 105). To reliably prevent the outflow of cargo oil in the event of damage or injury to the ship body due to stranding, collision or similar malfunction, the height (H) of the mid-height deck (1, 118) as measured from the ship bottom (8, 108) is determined so that the pressure of cargo oil exerted on an outer plate of the ship's side wall will not be higher than the pressure of sea water. An access trunk (5, 112) and pressure control devices (6, 7, 113, 114) serve for degassing cargo tank sections.

A method of and a system for controlling brakes. A target slip ratio of each of wheels at the start of antilock control is estimated and a vehicle deceleration prior to the start of the anti-lock control is detected. The target slip ratio at the start of the antilock control is corrected based on the detected vehicle deceleration. Thus, vehicle controllability correlated to the vehicle deceleration can be prevented from being impaired. It is therefore possible to reliably improve the control performance of a vehicle and to effect the optimum brake control.

Disclosed herein is a method of and a system for controlling brakes. In the brake control system, grounding loads on front and rear wheels are determined and a correction value for the braking of a predetermined wheel is computed based on the grounding loads thus determined. A braking force is determined inclusive of the computed correction value. A correction value for the braking of the front wheel is computed based on the determined grounding loads. Thus, the optimum brake control can be made without being affected by a variation in the distribution of the loads of the front and rear wheels relative to the ground.

A system for transporting roving bobbins in a cyclic manner between roving frames (1), spinning frames (2) and a residual roving clear-off process, in which the roving bobbins are transported by a carrier (7) driven by a tractor (14) along a main rail (3) arranged to form an endless loop and working rails (4, 5, 6) branched from the main rail (3). Dogs (28, 29, 30) for representing the respective frame address or the respective working rail address are disposed on the main rail (3) and detected by a sensor (34, 35, 36) mounted on the tractor (14). A station (68, 69, 70) is disposed in the inlet area of the roving and spinning processes for transmitting a command issued from a central control unit (71) supervising the system to the tractor (14). The command is prepared in accordance with information regarding the conditions of the tractor (14) and of the respective frames (1, 2) and working rails (4, 5, 6) and includes information regarding the frame address and/or the working rail address requiring the transportation of a carrier (7).
摘要:
The invention relates to a procedure of obtaining a lipid mixture rich in the content of .gamma.-linolenic acid or glycerides thereof from cultured fungus bodies of a filamentous Mortierella fungus. The invention proposes, on one hand, to fractionally extract the lipid mixture from the fungus bodies under mechanical disintegration in two steps first with an alcohol containing water to give a fraction rich in the polar lipids and then with a hydrocarbon solvent, e.g. hexane, to give a fraction lean in the polar lipids. The invention proposes, on the other hand, to enrich a lipid mixture relative to .gamma.-linolenic acid by fractionally crystallizing a part of a starting lipid mixture in a solution of a specified solvent so that the uncrystallized fraction in the mother liquor contains a lipid mixture in which the content of .gamma.-linolenic acid is remarkably increased in comparison with the starting lipid mixture.

A magnetic tape cassette system is described, comprising a magnetic tape cassette and a storage case therefor, wherein at least one of the magnetic tape cassette and the storage case is molded using a resin composition containing from 75 to 95% by weight of .alpha.-methylstyrene-acrylonitrile copolymer (A) and from 5 to 25% by weight of graft copolymer (B) obtained by reacting a polybutadiene-based rubber with monomers consisting of styrene and acrylonitrile, wherein said .alpha.-methylstyrene-acrylonitrile copolymer is a copolymer having a composition consisting of from 75 to 90% by weight of .alpha.-methylstyrene, from 10 to 25% by weight of acrylonitrile, and from 0 to 5% by weight of styrene, and 30% by weight or more of said .alpha.-methylstyrene-acrylonitrile copolymer is a copolymer component having a composition containing 82% by weight or more of .alpha.-methylstyrene.
摘要:
Guide bars are positioned to define the center of a magnetic recording medium by contacting the inner circumference of a circular hole of the magnetic recording medium. Through holes are positioned in a medium grasping portion of a lower hub at equal distances from the center of the lower hub. The guide bars are inserted into the through holes of the lower hub and engaged with the inner circumference of the circular hole of the magnetic recording medium mounted on the lower hub. The end portions of the guide bars are then pushed by an upper hub to which a double-faced adhesive member is secured, thereby moving said guide bars away from the surface of the magnetic recording medium and securing the double-faced adhesive member to the magnetic recording medium and the lower hub.
