PURPOSE:To prevent the occurrence of a double engaging state, by a method wherein, when the energizing level of a driven source is decreased to a first level or less, shifting from a first step to a second step is effected, and the energizing level is increased to a second level higher than the first level, shifting from a second step to a first step is effected. CONSTITUTION:CPU of a control devi...

PURPOSE:To improve safety of a vehicle, by a method wherein a relative position to a vehicle running in front is detected, and when an approaching state exceeds a given value, the speed change ratio of a speed change gear is controlled in a direction in which a car speed is decreased. CONSTITUTION:When it is detected by a controller 54 by means of a signal from a sensor 81 for a distance between c...

PURPOSE:To enable shifting of a reduction ratio to high or low despite of a running state, by providing a second switching valve which shuts off an oil passage running from first switching valve to the pressure chamber of each of driving and driven pulleys, and exerts a low or a high oil pressure on each pressure chamber through a bypass circuit. CONSTITUTION:A first switching valve 77 is controll...

PURPOSE:To prevent the occurrence of a delay in a speed change, by providing a switching valve, shutting off a drain circuit only before the starting of a speed change in a maximum speed change ratio, and a prefill valve, producing a prefill pressure, slightly lower than a speed change starting pressure, on the upper stream side of the switching valve according to a line pressure. CONSTITUTION:A s...

PURPOSE: To provide a wound coating material which has good tissue affinity, allows the permeation of bacterium-contg. secretions, i.e., pus, in particular, and maintains a good contact with a wound ground by providing a flexible and soft base net formed as a mat, fleece or woven fabric with ceramic or glass films. CONSTITUTION: This wound coating material is formed by combining many square bodies...

PURPOSE:To freely select a speed change characteristic suited to the taste of a driver by setting two types of fuel consumption-oriented and power performance-oriented speed change patterns. CONSTITUTION:An economy target primary-pulley rotating speed NPDe and a power target primary-pulley rotating speed NPDe are retrieved by a target primary-pulley rotating speed retrieving part 41 based on an ac...

PURPOSE:To facilitate braking operation at the time of emergency and improve safety by operating both functions of acceleration and braking with the same pedal. CONSTITUTION:A pedal 8 is installed on a link 1. And, a thrust bearing 9 is installed in such a way that the pedal 8 is axially movable within a predetermined range on the link 1. The lower part of the pedal 8 is temporarily held by an ext...

PURPOSE:To eliminate the trouble of operating a loading switch or inconvenience caused by forgetting the operation by comparing a clutch position at the time of starting with the clutch position at the time of neutral and judging a loading condition. CONSTITUTION:The control of engaging/disengaging a clutch 2 is carried out by the operation of a clutch actuator 21 and detected by a clutch sensor 2...

NEW MATERIAL:A compound expressed by formula I [-A-B- is formula II-IV (W is deuterium or tritium; X is methoxy or amino; n is 2 or 3; m is 0 or 1), etc.; either of R1 and R2 is carbamoyloxymethyl and the other is H or together may represent methylene (=CH2); Y is H or methyl; Z is H, methyl or acyl]. EXAMPLE:1a-N-Acetyl-7-dimethoxy-6,7-dihydro-7-ethylenedioxy-6-phenylse lenomi tomycin A. USE:For ...

A tire building drum (10) has a central shaft (13) and a pair of end drum assemblies (12) mounted for axial movement along the shaft. The end drum assemblies (12) include a main sleeve (19) slideable on the shaft (13), and an annular housing (24) mounted on the sleeve to form an annular chamber (32) surrounding the sleeve (19) which houses an annular piston (31). There is an annular expansion mean...

The device will be so developed to take account of prevailing operating conditions that an easy insertion and removal of the knife shafts (12, 13) is possible. The following measures are taken for this: the frame (1) consists of a cuboid structure which can be divided longitudinally into two halves (1', 1'') along the parting lines (10, 11), the bearing housings (2, 3) for the shaft journals (4, 4...

A power transmission system for a four-wheel drive vehicle having an automatic transmission has a differential operatively connected to an output member of the automatic transmission for providing the four-wheel drive vehicle. A hydraulic clutch is provided for locking the differential. A hydraulic control circuit is provided for applying oil at the line pressure of the automatic transmission to t...

A dialysis unit has a tank (2) divided into chambers by cation exchange membrane (1), e.g. made of a copolymer of styrene and divinyl benzene; an aqueous solution of hydroxylamine sulfate and a solution of nitric acid are placed in adjacent chambers and allowed to dialyse so that the NH3OH<+> and H<+> ions pass through the membrane and the nitric acid is converted to hydroxylamine nitrate as desir...
