Title: Automatic tracking lighting system
Inventor: FURUKAWA SATOSHI
IPC: H04N7/18
Filed: 1995-08-28
Abstract: PROBLEM TO BE SOLVED: To accurately automatically track an object without missing tracking even if the feature of the object changes by providing a pattern light irradiation portion and an object position detection portion which recognize the position of the object based on how the pattern light of an image is seen. SOLUTION: A pattern light irradiation portion 11 irradiates reference pattern light suitable for recognizing the distance, the surface shape, and the like of an object. A pattern extraction portion 52 conducts binary treatment on image data stored in an image memory 51 so as to extract the pattern image irradiated by the irradiation portion 11. A pattern analysis portion (an object position detection portion) 53 analyzes the distance to the object and its shape based on the pattern image extracted by the extraction portion 52, and further by adding the movement direction and the distance from the last time position, and the like so as to correctly discriminate whether it is the tracking object or not with high probability. Thereby, since a rotation base 3 can be attitude- controlled so that the radiation direction of a spotlight always faces in the direction of the object via a rotation base movement vector production portion 54, and a rotation base control portion 4, the object can correctly be tracked.

Title: Refrigerant evaporator
Inventor: NAGASAWA TOSHIYA
IPC: F28D1/03
Filed: 1992-08-18
Abstract: PURPOSE:To provide drain from staying at a lower portion of a refrigerant evaporator with a higher heat exchange rate but without causing bending of any fin. CONSTITUTION:A refrigerant evaporator comprises a plurality of tubes each of which is constructed by joining a pair of plates 3, and which are laminated through corrugated fins interposed therebetween. A refrigerant passage 4 in each tube is turned at the lower portion of the refrigerant evaporator. Each plate 3 permits a peripheral edge joint surface 7 to be extended to the inside of the plate 3 at each corner of the same so as to prevent the refrigerant passage 4 from being formed at each corner of the plate 3 and at the lower portion of the plate 3. Hereby, the refrigerant passage 4 is formed into a substantially V shape. Accordingly, an interval between the adjacent tubes is increased at the corner of the tube and at the lower portion of the same. Thus, drain flows downward at the corner of the tube and at the lower portion of the same to prevent the drain at the lower portion of the refrigerant evaporator from staying there.

The tightening sleeve 13 which is composed of stainless steel maintains the interval in the radial direction from the cable insulators 6, 7 by using a porous tube 17 which is composed of a gas-permeable PTFE material, and it covers the gas permeation regions in the cable insulators 6, 7. Thereby, the air can be ventilated freely up to the inside of the cable insulators 6, 7 through the porous tube 10, the traverse- direction hole 15 and the gas permeation regions.

Abstract: PROBLEM TO BE SOLVED: To change the state of seawater, suppress adhesion of an oceanic life and remove an obstruction in the case where seawater is utilized as cooling water by applying the alternating voltage of a rectangular wave in seawater, and bringing it into contact with a metal surface in a laminar flow state. SOLUTION: Metal electrodes 23, 24 of the same material are provided in a metal housing 22 of cupronickel, titanium and the like in a voltage type water treatment device 20, and alternating rectangular wave voltage of approximately one to hundreds MHz is applied by an alternating voltage generation device 27 connected to a commercial alternating power source through conductors 25, 26 to make treating water 29 of original water 28 of seawater. When the treating water 29 is brought into contact with metal piping of cupronickel, titanium and the like and the interior face of a cooling tank in a laminar flow state, water molecules in which polarization is enhanced are electrically arranged on and adhered to a metal surface, and adhesion of an oceanic life such as an oyster and a barnacle is suppressed. In the case where it is a turbulent flow state and carbon material and the like, a suppression effect does not generate. Thereby the oceanic life adhesion prevention is relatively inexpensively enabled without problem of environment destruction and the remaining of toxic material.

Title: Speed controller of dc motor
Inventor: TANAKA HIROTOMO
IPC: H02P7/06
Filed: 1984-10-19
Abstract: PURPOSE:To obtain the constant control accuracy for arbitrary speed mode by setting the value of a current flowing time in accelerating and decelerating zones at every speed mode. CONSTITUTION:A frequency generator 102 mounted on the shaft of a motor 101 outputs a signal 107 of the frequency proportional to the rotating speed, and a waveform shaper 108 outputs a timing signal 109 shaped in the waveform from the signal 107. A CPU 108 starts the motor and compares the period of the edge zone of a timing pulse with a reference set value t1 after the prescribed time. When it is longer than the reference set value, a current is flowed for the prescribed time tsl in the next edge zone. When it is shorter than the reference set time, a current is flowed only for the prescribed time tfl in the next edge zone. The current flowing times tsl, tfl are stored in advance in response to the characteristics of the motor, the desired rotating speed and the load of a carriage system.

Title: Water-absorptive-resin slurry
Inventor: SHIMOMURA TADAO
IPC: C09K8/02
Filed: 1987-09-04
Abstract: PURPOSE:To obtain a water-absorptive resin slurry which can be pumped without reducing the water absorptivity of a water-absorptive resin and can be used for civil engineering works, etc., by incorporating a water-absorptive resin into a dispersion medium consisting of a water-soluble organic substance and water. CONSTITUTION:A water-absorptive resin slurry is prepared by incorporating 5-300pts.wt. water-absorptive resin (e.g., a hydrolyzed starch/acrylonitrile graft polymer) into 100pts.wt. dispersion medium consisting of 40-95wt.% water-soluble organic substance [e.g., a glycol compound of formula I (wherein l and m are each 0 or 1-1,000 and l+m is 1-1,000) or a glycerin compound of formula II (wherein n is 1-20) (e.g., polyethylene glycol or glycerin)] and 60-5wt.% water. Because of the low rate of sedimentation of the water- absorptive resin in the slurry and the good fluidity of the slurry, this water- absorptive resin slurry is easy to pump. Since the amount of water is so small as compared with the weight of the water-absorptive resin that little reduction in the water absorptivity of the resin will be caused. Therefore, this slurry can be widely used in applications such as civil engineering, construction, and fire fighting.
