Filed: 1999-04-27
Abstract: PROBLEM TO BE SOLVED: To avoid the engagement shock of a clutch by executing a quick pressure boosting-up control for increasing the feeding speed of oil in the initial stage of the oil feed for engaging a prescribed clutch, and regulating the execution of quick pressure boosting-up control when the quick pressure boosting-up control is continuously execute within a short time. SOLUTION: Since an oil pump 9 interlocked with an engine is also stopped when the engine is automatically stopped, the line pressure PL within an oil passage to a forward clutch C1 is reduced to open the forward clutch C1. When the restart condition that 'even one of automatic stopping conditions of the engine is not satisfied' is established, the engine is restarted. At this time, since the oil is not present in oil passages 59, 66, a quick pressure boosting-up control is executed. After the restart processing of the engine, it is judged whether the engine restart processing is succeeded or not, and when the failure of the engine restart processing is judged, the quick pressure boosting-up control to be performed next is regulated.

Filed: 1997-05-09
Abstract: PROBLEM TO BE SOLVED: To provide compact and inexpensive circuit configuration immune to the influence of phase deviation in the transmission characteristics of transmission line by setting the frequency of carrier wave within a specified frequency range and setting that frequency lower than a specified frequency as the clock of pseudo noise generating means. SOLUTION: A carrier wave generating means 1 outputs a carrier wave (b) at 153.6 kHz and a 1st pseudo noise generating means 2 generates a 1st pseudo noise (c) with the clock pulse of 38.4 kHz, for which the frequency of carrier wave (b) is divided into four stages, as a clock. A modulator 3 performs the spread modulation of information signal (a) based on the pseudo noise (c). A 1st mixer 4 outputs spread information (e), for which the product multiplication of output (d) from the modulator 4 is performed with the carrier wave (b), and outputs it through a band limiter 5 and a coupler 6 to a lighting line as spread information (f).  Thus, since the frequency of carrier wave (b) is set within the range from 100 to 200 kHz and the frequency of clock is set lower than 50 kHz, the phase deviation of information signal f' caused by the lighting line can be suppressed less than πrad and communication can be surely performed.

Filed: 1982-07-09
Abstract: PURPOSE:To form a fin having wavy surface, by constituting a rolling roll having a diametral difference on its rolling surface, in a method of manufacturing a fin to be wound around a heat transfer pipe of a heat exchanger by rolling it between rolling rolls. CONSTITUTION:A helical fin is obtained by continuously feeding a blank fin material and passing it between rolling rolls positioned so as to have a prescribed opening angle between their axes. Here, one roll of a pair of rolling rolls, i.e. in a small-diameter rolling roll 21, for instance, a roll diameter at the side of the rolling surface 21a is made larger between the surface 21a where the outer peripheral part of the material passes and the rolling surface 21b where the inner peripheral part of it passes. Thus the surface rolled by the surface 21a and equivalent to the outer peripheral part of the fin, receives a rolling force larger than that of the inner peripheral part of the fin, and then the reduction rate of the former is larger than that of the latter. Therefore, a buckling phenomenon is caused by the difference of the reduction rate and the strength, etc. between the former and the latter, and a fin 3 having wavily formed surface is obtained.
