Title: Muffler protector structure in engine for working machine
Inventor: MORIYAMA HIROSHI
IPC: F01N13/18
Filed: 1994-12-28
Abstract: PURPOSE: To enable the temperature rise of an upper side wall part of a protector main body to be avoided by interposing a thermal insulating plate between the facing surfaces of the upper side part of an exhaust muffler and the protector main body, and making the protector main body by synthetic resin. CONSTITUTION: An exhaust muffler M provided on an engine E is covered with a muffler protector Pm, and a cooling fan (f) is covered with a fan cover Pf. Respective main bodies of the muffler protector Pm and the fan cover Pf are integrally formed of synthetic resin. An approximately parallel thermal insulating plate S is interposed between facing surfaces of the upper side wall part 7u of the protector main body 7 and the upper side part 8 of the exhaust muffler M so as to be made eccentric to the upper wall part 7u side. Hot air to rise from the exhaust muffler M can be effectively prevented from being transmitted to the upper side wall part 7u of the protector main body 7 by the thermal insulating plate S.  The muffler protector structure is effective in preventing excessive heating of the upper wall part 7u, and any trouble is not generated even if the protector main body is made of synthetic resin.

IPC: B66C13/22
Filed: 1996-12-10
Abstract: PROBLEM TO BE SOLVED: To perform the setting of an optimum material handling route by performing a desk simulation test again upon correcting the setting conditions in the case where a fact that a lifting cargo passing through a material handling route collides with an obstacle is judged as the result of the desk simulation test. SOLUTION: As a track pattern of a lifting cargo (n), both winding and traversing simultaneous operating patterns are selected (S1, S2 and S3). Next, in making a certain optional material handling route model as an object, a temporary setting value is determined. In brief, a winding speed pattern and an unwinding speed pattern or the like are set up (S4 and S5). Next, on the basis of this setting condition, a desk simulation test is performed, and a material handling route of the lifting cargo and a deflected variable or the like are calculated.  In consequence, the lifting cargo passing through this material handling route is deflected to some extent while both winding and traversing motions are simultaneosuly carried out, by way of example, and when a fact that it collides with a freight at the side of a specified spot is judged, times of both traversing and unwinding starting points are little delayed, and then the desk simulation test is performed again.

Abstract: PURPOSE: To suppress vibration and noise by a method wherein the torque pattern of a motor is multiplied by a coefficient for every r.p.m. thereof to operate a new torque pattern and the torque is controlled based on the new torque pattern. CONSTITUTION: A control circuit 10 determines a conduction switching timing for the armature winding of a brushless motor 1 based on a position detection signal received from a position detection circuit 3 and delivers a drive signal to each switching element U-Z in a drive circuit 2a. A duty output signal for turning the ON interval of a switching element X, Y, Z specifically based on a rotational speed command is also outputted. The r.p.m. is then detected and the duty ratio is regulated to attain a target r.p.m. In this regard, the control circuit 10 multiplies a torque pattern in a torque pattern ROM 10c by a coefficient in a coefficient ROM 10d depending on the r.p.m. to determine a torque pattern and then controls the torque according to a torque pattern operated for every one twelfth period thereof.  This method suppressed fluctuation of torque thus reducing vibration and noise.

Filed: 1995-11-24
Abstract: PROBLEM TO BE SOLVED: To provide the method of safety and effectively separating and recovering gasoline vapor in a gasoline tank and to provide the device therefor. SOLUTION: Gasoline vapor containing gasoline is introduced from the bottom part of an adsorber 1 to adsorb gasoline from the gasoline vapor by an adsorbent with which the adsorber 1 is packed and to discharge air from the top of the adsorber 1, and also, the adsorbed gasoline by the adsorbent is recovered. In this case, as the adsorbent, silica gel subjected to hydrophobic treatment is used.

Title: Measuring apparatus for physical property value and surface temperature of processed material
Inventor: MARUI TOMOTAKA
IPC: G01J5/00
Filed: 1991-11-19
Abstract: PURPOSE:To simultaneously measure the value of physical properties of the surface of a processed material and the surface temperature thereof by searching and calculating the value of physical properties from the luminous temperature obtained by a two-color pyrometer, and performing two-color pyrometry by means of an operating means. CONSTITUTION:An operating block 12 calculates the power ratio of the emissivity epsilon1<lambda1>/epsilon2<lambda2> in accordance with the calculating formula with the use of the luminous temperatures S1, S2 input from a two-color pyrometer 10. In the formula, C2 indicates plank's second constant of. An operating block 14 calculates a first emissivity ratio from the power ratio, and a temperature calculating block 16 calculates tone surface temperature T. A presuming block 18 presumes and sets the thickness (d) of an oxide film at an optional value. An operating block 20 calculates the emissivity from the presuming value of the film thickness and the measuring two wavelength lambda1, lambda2. A dividing block 22 calculates a second emissivity ratio. A judging block 24 obtains the difference of the second emissivity ratio and the first emissivity ratio. The correcting amount DELTAd is calculated in a block 26 when the square H of the difference is not equal to 0. The film thickness (d) is corrected in a block 28. While the operations are repeated with using the (d), the (d) is output when the H becomes approximately 0. Accordingly, both the surface temperature T and the film thickness (d) of the oxide film can be measured.
