Title: Cooling device
Inventor: KIKUCHI MASAKAZU
IPC: F25D17/06
Filed: 1998-11-18
Abstract: PROBLEM TO BE SOLVED: To provide a means for avoiding the resonance state of a fan. SOLUTION: A pulse signal SP with reference duty ratio corresponding to a target speed is outputted to a chopper circuit (S1), and a DC voltage is applied to a fan motor. While the fan motor is being rotated, temperature in a machine room where the fan motor is provided is detected (S3), and the reference duty ratio is reset when the detected temperature is equal to reference one (S5). When the detected temperature is higher than the reference one, the deviation width of the speed is calculated based on the temperature-speed characteristics of the fan motor being given in advance (S7), and the duty ratio of the pulse signal PS is decreased according to the deviation width (S8).  On the other hand, when the detected temperature is lower than the reference one, the duty ratio of the pulse signal SP is increased (S10), thus controlling the fan motor at a constant speed, and preventing resonance due to coincidence with the natural frequency of a blast blade in advance.

IPC: G01N29/22
Filed: 1990-11-28
Abstract: PURPOSE:To measure the elastic constant and elastic property of an object with the reflected wave intensity independent from the frequency of ultrasonic waves by changing the incidence angle of an ultrasonic lens with an incidence angle control means. CONSTITUTION:When a stepping motor 51c connected to the main spindle of a theta-axis goniometer 51 for setting the incidence angle is rotated, a tilt table 51b is tilted in the theta-direction. A ultrasonic lens 100i is swayed in the theta-direction via constituting elements fitted to the lower horizontal plane 51e of the table 51b, and it is stopped at the proper incidence angle in response to various measurement. When ultrasonic waves are radiates to the surface of an object 13 at a specific incidence angle, elastic surface waves are excited on the surface of the object 13, the intensity of reflected waves is reduced, if the reflected wave intensity is measured, the phase is changed at the specific incidence angle, when the change of the phase is detected by a phase analyzing means, the elastic property of the object 13 can be quantitatively evaluated based on the detected result.

IPC: C21B5/00
Filed: 1987-12-24
Abstract: PURPOSE:To effectively restrain Si in molten iron by premixing mill scale and flux into pulverized coal at the time of blowing the pulverized coal into a blast furnace from a tuyere. CONSTITUTION:Pulverized coal is blown into the blast furnace from a tuyere to reduce fuel cost and reform furnace gas.

Title: Adhesive applicator
Inventor: ISHIMARU ICHIRO
IPC: B05C5/04
Filed: 1989-12-20
Abstract: PURPOSE:To quantitatively apply an adhesive with high precision of coating amt. resolving power by forming a part of the passage extending from an adhesive tank to an orifice or providing a piezo element for vibrating a part constituting the passage and a pulse power source connected to the element. CONSTITUTION:A pulse voltage is impressed on the piezo element 4, hence the element 4 is minutely vibrated, and an adhesive 9 is excited by the minute pressure. The pressure wave is transmitted toward an adhesive tank 14 and an orifice 2, and the surface of the adhesive 9 is bulged when the pressure wave reaches the orifice 2 which is a free end. At this time, when a sufficiently high pulse voltage is impressed with respect to the viscosity of the adhesive 9, the discharging power exceeds the power to pull the adhesive inward, and the adhesive 9 is flown as droplets 19 to the surface to be coated, and the surface is coated. Since the adhesive 9 is micronized in this way, the adhesive is quantitatively applied with high precision of coating amt. resolving power irrespective of the state of the tip surface of the applicator and surface to be coated.

Filed: 1988-12-28
Abstract: PURPOSE:To make it possible to detect dispersion readily and highly accurately with a simple optical system by a simple operation by obtaining optoelectronic transduced outputs having specified signal intensities from optoelectronic transducing surfaces held by two parabolas, and operating the dispersion of a light spot from the outputs. CONSTITUTION:A light beam from a light source 11 is projected on an optical disk 10 through an optical system. The reflected light is inputted as a light spot in a specified position 14e of an optoelectronic transducing surface 14a of a DI sensor 14 through the optical system. The surface 14a is insulated and isolated along two parabolic insulating grooves 14A and 14B whose apexes are approximately in contact at a center O. The surface is divided into three optoelectric transducing surfaces 14b-14d. Optoelectronic transduced outputs VU and VD are obtained from the surfaces 14c and 14d. Outputs VL and VR are obtained from the right and left surfaces 14b. At first, an operating means 15 obtains the sum of the outputs VL+VR which is determined by the energy of the incident light at the shaded part under a preset assumption. Since the sum is proportional to the dispersion of the light spot, the proportional expression is operated, and the dispersion sigma is obtained. The dispersion sigma is substituted into the specified expression, and the upper and lower displacement DELTAx on the disk 10 is operated and detected.
