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).

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.

An apparatus for measuring the viscosity of a viscous substance as a sample to be measured has a tuning fork type vibrator having two vibrating plates opposing to each other at a distance. These vibrating plates are vibrated at equal frequencies in inversed phase relation to each other by means of a variable vibration generator. The vibrating members have thin plate-like sensitive members provided at their respective lower ends. An amplitude obtained by immersing the sensitive members in a viscous substance and vibrating the former is detected by a pickup device to detect a change in amplitude according to the viscous resistance of the viscous substance thereby to measure the viscosity thereof. The viscosity measuring apparatus has means for regulating the frequency of the vibration generator so as to vary the frequency according to need. Thus, when the relationship between viscosity and responsive vibration no longer maintains a substantially linear relationship at a predetermined driving frequency, the setting of the driving frequency is renewed, thereby allowing viscosity to be measured over a wide range and with a high accuracy.

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.

In a magnetic disk cartridge, a slide valve for prevention of erroneous erasure is slidably supported in a cartridge case having a detection hole adapted to be closed by the slide valve when the slide valve is at a predetermined sliding position. A resilient lock arm having projections at the ends is positioned on a side face of the slide valve integrally therewith. A pair of recess portions are positioned integrally with the case for receiving and retaining the projections of the lock arm, so that one of the projections is retained and stopped in one of the recess portions when the slide valve is at the sliding position for closing the detection hole the other projection is retained and stopped in the other recess portion when the slide valve is at the sliding position for opening the detection hole.

A Phillips-type magnetic tape cassette in which widthwise motion of the tape is restricted. The cassette has rotary guide rollers arranged at both ends of the front part of the cassette for guiding the running of the magnetic tape. A shaft supporting each rotary guide roller is cylindrical and has a slit extending in the axial direction and a circumferential annular groove formed in the outer wall in a middle region. Each rotary guide roller has circumferential engaging protrusions extending from the inner wall thereof, which are inserted into the annular groove so that the rotary guide roller is pivotally mounted on the supporting shaft.
