IPC: F02P5/145
Filed: 1989-01-20
Abstract: PURPOSE:To secure accurate accelerability according to a decrease of engine speed variations by performing timing delay compensation with a larger condition than an accelerating threshold value at the first time of a variation in engine speed, while performing the timing delay compensation with a retard value conformed to a speed variation range from the second time downward. CONSTITUTION:In a compensation control system for a snatch reducing countermeasure installed in a control unit 20, there are provided an acceleration judging part 26 judging acceleration on the basis of a fundamental fuel injection quantity Tp and a calculating part 27 calculating a fundamental threshold value Nb to engine speed N. Also there is provided a calculating part 34 calculating an accelerating threshold value NB from this value Nb and an offset value alphadetermined according to throttle opening phi. After acceleration starting, ignition timing thetaIG is compensated (24) by a retard initial value thetaL1 being outputted out of a retard value control part 36 under the condition of N>NB at the first time speed variation, but by a retard value thetaL(P) being outputted out of a retard control part 30 under the condition of N>Nb at the second time downward, respectively.

IPC: H01S3/098
Filed: 1984-01-26
Abstract: PURPOSE:To obtain CO2 lasers capable of mode switching with one change-over switch by a method wherein a restricting means is provided between an electrode and a transmission mirror. CONSTITUTION:The restricting means 7 is considered in such a manner that the center hole comes as round as possible by an increase in mumber of blades. Al or the like is suitable for the material of the blades, and the diameter of the restriction hole can be varied by connection of said means to a small-sized stepping motor, etc. and by changing over a switch. For example, providing a three- step change-over switch and switching the diameter of the throttling hole as follows enable mode instantaneous-switching by a piece of electric-powered throttling means 7, which also can serve as an inner shutter. In other words, in the case of using the restricting means for the inner shutter, the throttled diameter is set small: the diameter is set at approx. 12m/m if it is required to lead out single-mode laser beams. If multi-mode laser beams are necessary for welding, the diameter can be set large.

Title: Picture signal processor
Inventor: HAYATA YUJI
IPC: G06T5/00
Filed: 1990-01-25
Abstract: PURPOSE:To attain a proper multi-level processing in response to the density distribution of an original picture by forming a density histogram from an analog electric signal representing picture information and selecting a read density range of the picture from the histogram. CONSTITUTION:A light from an LED array 23 is reflected in an original S and radiates to a sensor 22 via a rod lens array 21. The sensor 22 generates an output in response to the radiating light and inputs it to an A/D converter 203 via an amplifier 202. The converter 203 compares an output of the amplifier 202 with a reference value set initially and converts the result into an 8-bit digital value. The converted picture data is stored in a RAM 209 and a CPU 207 generates a histogram. When the read picture data does not appear a reference level B0 being a bright level as shown in separate figure, a level of a 2nd D/A converter 205 is reset from B0 to Dx (in this case B2) so that the density range from A0 to B2 is able to be converted into an 8-bit digital value by the converter 203.

IPC: A45D19/14
Filed: 1993-01-29
Abstract: PURPOSE:To shorten the initial draining time which is not related to a hair washing operation in an automatic hair washing machine. CONSTITUTION:When hot water supply is started, a drain valve and a hot water storage valve are opened until a water level in a hot water storage tank reaches the upper limit water level H, and also, a pump is driven by a frequency 3Hz S4, S6. Thus, hot water is supplied into the hot water storage tank, and simultaneously, hot water stored in the hot water storage tank is pumped out by a sufficiently slower flow rate (flow velocity) than a flow rate (flow velocity) of hot water supplied into the hot water storage tank, and discharged to the outside through a drain tube. Subsequently, when it is judged that a water level reaches the upper limit water level H, basing on an output signal from an upper limit water level sensor, the drain valve and the hot water storage valve are closed, and also, the pump is stopped S6, and hot water supply is finished. In such a manner, in the course of hot water supply, cold water collecting between the hot water storage tank and a pumping-out means, etc., can be removed, and at the time of initial drain, it will suffice that only cold water retained in the pump and pipeline to a nozzle is drained.
