Title: Latent heat accumulator
Inventor: KUSUDA TAKAO
IPC: F28D20/02
Filed: 1982-02-16
Abstract: PURPOSE:To obtain a sufficient thermal output without causing phase separation, in the latent heat accumulator in a solar water heater and the like, by horizontally  stacking flat containers wherein latent heat storing material is sealed with an interval  being provided, and making the parts between the containers a fluid path. CONSTITUTION:The high temperature water of about 58 deg.C or more from a solar heat  collector and the like flows the path 4 between the stacked flat containers 3 wherein  the latent heat storing material 2 is sealed. Heat is exchanged at the outer walls of  the flat containers and the heat storing material 2 is melted. The heat is stored and  the water is taken out of a hot water outlet port 6. Then low temperature water is  flowed into the path 4 from a water inlet port 5. The water takes the latent heat out  of the heat storing material 2 and the temperature of the water is increased. The water is taken out of the hot water outlet port 6. At this time, the heat storing material 2 begins to solidify, and a solid layer whose heat conductivity is poor grows from  the container walls. Since the thickness of the container is thin, the temperature difference can be kept small. The complete phase separation, under which the solid material sinks due to the difference in specific gravity and thin aqueous solution remains at  the upper part, does not occur.

Title: Fuel injection timing adjustor
Inventor: NAKAMURA MASAYUKI
IPC: F02B3/06
Filed: 1988-02-04
Abstract: PURPOSE:To adjust the fuel injection timing in simple manners according to the environmental temperature by shifting a stopper member according to the environmental temperature when the engine starts and projecting the stopper member between a pair of weights which adjust the fuel injection timing through spreading. CONSTITUTION:When the engine revolution speed increases, a plurality of weights 15a and 15b spread against a plurality of springs 22 and 23, and a plurality of eccentric cams 13 and 14 turn in the counterclockwise direction. Therefore, the relative turning angle between a housing 10 which is revolved in synchronization with a Diesel engine and a hub 11 connected with the camshaft of a fuel injection pump varies, and the injection timing is adjusted. In this case, if the environmental temperature rises, a spring 25 is extended, and the load applied onto a stopper member 24 increases. Therefore, the stop member 24 projects between the weights 15a and 15b, and the return of the weights 15a and 15b in the closing direction is engaged.

Title: Method of machining outside diameter of pipe having aperture
Inventor: KOBAYASHI MASAHIRO
IPC: B23P17/00
Filed: 1988-02-02
Abstract: PURPOSE:To carry out the highly accurate machining of the outside diameter dimension and straightness of a pipe having an aperture on the peripheral wall by forming a groove hole along the inner wall face of the aperture to be formed on the peripheral wall of pipe while leaving the peripheral wall in part and, after carrying out the finishing polishing of the outside diameter face, cutting the remaining portion. CONSTITUTION:After roughly machining the outside diameter face of a pipe 10 to be machined having no hole, a groove hole 12 is opened along the inner wall face 11 of an aperture to be formed on the peripheral wall 10a of the pipe 10 while leaving the peripheral wall in part. Thereby, a part 13 of the peripheral wall of the pipe 10 remains inside the aperture to be formed with its peripheral wall edge being in close vicinity to the inner wall face 11 while, at the same time, the part 13 is left linked to the peripheral wall 10a with the bridging portions 14 which are left uncut. Also, due to the perforating machining, the peripheral wall in the vicinity of the groove hole 12 is deformed by a residual stress. Then, the outside diameter face of the pipe 10 is subjected to close finishing polishing. In this case, since the part 13 of the peripheral wall remains on the aperture portion, the polishing stone is guided and slides on the outside diameter face of the part 13 of the peripheral wall passing on the inner wall face 11 in the advancing direction. Hence, no chipping off of the abrasive grains out of the polishing stone due to an edge portion occurs while removing the deformed projecting portion caused by the residual stress by means of polishing, forming a complete aperture 15.

Title: Nitrogen oxide measuring apparatus
Inventor: KATO NOBUHIDE
IPC: G01N27/416
Filed: 1997-02-07
Abstract: PROBLEM TO BE SOLVED: To enable measurement of oxide by a method wherein oxygen of a gas to be measured undergoes a pumping treatment by a main pump means to adjust the concentration thereof and another pumping treatment is performed based on an interelectrode voltage by a measuring pumping means to detect a pump current corresponding to the amount of the oxygen. SOLUTION: A gas to be measured is introduced into a first chamber 54 through a diffusion speed control section 58 to control the partial pressure of the oxygen in the first chamber 54 controlled to a specified value by a main pump cell 68 and the atmosphere of the first chamber 56 is introduced into a second chamber 5 through a diffusion speed control section 60 to analyze nitrogen oxide. The oxygen then generated is drawn by a measuring pump cell 84 and an ammeter 88 detects a pump current Ip2 flowing with the action of the cell 84 to d measure the amount of the nitrogen oxide in the gas to be measured. An internal pump electrode 64 and a measuring electrode 72 in the first chamber 54 are built up with a cermet electrode containing 0.01-1% of gold and the balance of an alloy mainly composed of a platinum family element.  Thus, a low activity as decomposition catalyst of the nitrogen oxide in the method eliminates possible decomposition of the nitrogen oxide under a low partial pressure of the oxygen thereby enabling highly accurate measurement of the nitrogen oxide.
