Title: Heat medium circulation type waste heat recovery method
Inventor: NAKANO SHINYA
IPC: F28F27/02
Filed: 1982-01-16
Abstract: PURPOSE:To greatly increase the amount of heat to be recovered without causing corrosion at low temperatures, etc., by a method in which the amount of  waste heat to be recovered is controlled by adjusting the amount of a heat  medium passing through a preheating side heat exchanger according to a difference between the temperature of a waste heat recovery side heat exchanger  and a given temperature. CONSTITUTION:A waste heat recovery side heat exchanger 1 and a preheating side heat exchanger 2 are connected with a heat medium circulation rout 3. In this case, the heat medium circulation rout 3 is connected with a heat meidum circulation bypass rout 5 provided with a flow rate regulating valve 4, and a thermometer 6 is set to the waste heat recovery side heat exchanger 1. The flow rate regulating valve 4 is controllably fedback (or fed forward in case where shortening of answer delay is necessary) in such a way that temperatures detected by the thermometer 6 become a given temperature, or the lower limit control temperature for low-temperature corrosion, and the amount of heat medium passing through the preheating side heat exchanger 2 is controlled. By  this, the expected purpose can be effectively attained.

Title: Extension pipe and vacuum cleaner
Inventor: OIKAWA YOJI
IPC: A47L9/24
Filed: 1997-01-13
Abstract: PROBLEM TO BE SOLVED: To keep airtighness of the engagement part between the outer pipe and inner pipe of an extension pipe of a vacuum cleaner without preventing the inner pipe from sliding forward/backward inside the outer pipe even when a force is given to the inner pipe to be slanted. SOLUTION: This extension pipe has an inner pipe 22 and an outer pipe 21. The inner pipe 22 is inserted into and engaged with the outer pipe 21 so that the inner pipe 22 can slide forward/backward inside the outer pipe 21. And a stopper means 68 consisting of a cylindrical stopper part 65 and fixing part 66 which clasp a ring-shaped packing 67 almost in the center is installed on one end of the outer pipe 21. A dented notch 82 is formed at the end rim of the fixing part 66 in the axial direction. A stopper 86 as a rotation stopper, which protrudes in the radius direction and is inserted into the notch 82 to be in contact, is integrally formed at the insertion end of the inner pipe 22 to be inserted into the outer pipe 21.  When the extension pipe 20 is extended to the longest in cleaning, the inner pipe 22 is slanted as against the axis of the outer pipe 21 with the extractionproof means 68 as the center by clearance of the extractionproof means 68. The outer surface of the inner pipe 22 is brought into contact with the inner rims opposite both ends of the extractionproof means 68, and gaps are made on the opposite side. Since the gap at the packing 67 is narrow, the gap is absorbed by the recovery of the elastic deformation, so the airtightness can be maintained.

Title: Moving direction judging device for moving body and entering and leaving number counting method using this device
Inventor: OGAWA SHOHEI
IPC: G06M7/00
Filed: 1992-01-13
Abstract: PURPOSE:To reduce the required number of detecting sensors for monitoring a moving body by providing a perforated plate changed in its transmission area in the moving direction of the moving body, and detecting light and heat rays transmitted through the perforated plate by a sensor so as to judging the moving direction by a change with the elapsed time of detection output caused by the passing of the moving body. CONSTITUTION:The perforated plate 3 of a detector 2 is provided with through holes 31 changed in the opening width so as to change transmission area toward the advancing direction of a passing person, and each through hole 31 is formed of a wide hole and a slit. A CdS light receiving element 23 is disposed above the perforated plate 3. The detector 2 is installed at the ceiling of a passage in the state of the longitudinal direction of the through holes 31 coinciding with the passage direction. When the passing person crosses below the wide hole, the light reflectance of the passing person is generally smaller than that of the floor surface, so that the output of the light receiving element 23 is reduced suddenly, and becomes the smallest right under the wide hole and thereafter is increased gradually into the initial standard value. When the passing person crosses from the slit side, the output is gradually reduced in the beginning and increased suddenly afterwards. This change is data-processed to allow the moving direction of the passing person to be judged and entering and leaving persons to be counted separately.

Abstract: PURPOSE:To enhance a hermetic property, by using an electron beam to cause sputtering in a vacuum to make an aluminum oxide film on the surface of an electroconductive member provided with an electrode, when the member is sealed at the end of a light emission tube. CONSTITUTION:An electroconductive member 6 made of niobium or the like and provided with an electrode 4 is sealed in each of end disks 2 at both the ends of an alumina tube 1 to manufacture the light emission tube of a high- pressure sodium-vapor lamp. Aluminum oxide is sputtered by an electron beam in a vacuum to make an aluminum oxide film 7 on the outside surface of the electroconductive member 6. A ceramic cement 8 is provided in the hole 3 of the disk 2 to hermetically seal the hole as the cement extends through the hole. Since aluminum oxide is dissolved into the ceramic cement 8 out of the aluminum oxide film 7 and the disk 2 to firmly conjoin the electroconductive member 6 and the disk to each other, sodium is surely prevented from leaking out of the light emission tube.

IPC: B01F25/46
Filed: 1997-01-14
Abstract: PROBLEM TO BE SOLVED: To adjust the finely pulverizing effect without changing a nozzle. SOLUTION: A high pressure fluid containing a material to be finely pulverized which is introduced through a flow route inlet 1 of a closed container 1 is divided to a plurality of nozzle rows 5 installed in a movable axis 4 and converted into a plurality of high speed flows and the high speed flows are jetted out to a route 6 for collision which forms a gap between the inner wall of the closed container 3 and the movable axis 4, and come into collision against the wall face and thus finely pulverized. Since the movable axis 4 is brought into contact with the inner wall of the closed container 3 except the part where the route 6 for collision is formed, the outlet of a nozzle 5b is blocked when the outlet deviates from the range of the route 6 for collision.  Consequently, the pressure of the fluid which is going to collide can be adjusted by moving the movable axis 4 back and forth in the closed container 3.

Filed: 1988-01-12
Abstract: PURPOSE:To simplify the mechanism by use of an electrode plate which is made of several pieces of metal embedded in a water mount and a metal plate placed at the specified height above the mount and a capacity meter. CONSTITUTION:The detector consists of a mount 11, several rectangular metal pieces 12 embedded in the mount 11, a metal plate 13 placed at the specified height above the mount 11 and a capacity meter 15, one terminal of which is connected to the metal plate 13 and the other terminal of which is connected to a selector switch 14 which switches the connection with each metal piece 12. The capacity meter 15 measures the capacity of a parallel plate capacitor which has a metal piece 12 selected by switching of the switch 14 and the metal plate 13 as electrodes. In other words, when a wafer is placed on the mount 11, the ratio of the portion which is covered by the wafer is calculated for each metal piece 12 by measuring the capacity of a capacitor which is made of each metal piece 12, and thereby a location of an orientation flat against the mount 11 can be gained. By this method, a simplified mechanism and a low-cost equipment are available.
