Title: Heat exchanger
Inventor: MITANI AKIO
IPC: F28D1/04
Filed: 1980-03-12
Abstract: PURPOSE: To reduce the thickness of an inner tube of a heat exchanger constructed in a double structure having two independent passages used for a domestic hot- water supply and hot-water room heater or the like and to incorporate sufficient pressure rsistant strength in the inner tube by inserting reinforcing element into the inner tube.  
     CONSTITUTION: A circular pipe 10 opened at both ends or flat plate is inserted between the inner surfaces of the recesses 5a and 5b of the inner tube 3. Since the recesses 5a, 5b of the inner tube 3 are supported by the pipe 10 or flat plate even if the pressure in the passage between the outer tube 1 and the inner tube 3 is raised, the pressure resistant strength can be increased. Accordingly, even if the thickness of the inner tube 3 is reduced, sufficient pressure resistant strength can be incorporated in the inner tube.

IPC: F16F13/00
Filed: 1982-02-26
Abstract: PURPOSE:To change the supporting characteristics of a mounting device by a constitution wherein an elastic body having a fluid chamber inside is provided with an outside force applying means changing the form of the elastic body from outside, and thereby the quantity of the change in the form of said elastic body is adjusted to change the internal pressure thereof. CONSTITUTION:A power unit 14 is fixed on the upper surface of a first disc- shaped bracket 12 by a bolt 13, while a second disc-shaped bracket 15 is fixed on the lower surface to a car body 17 by a bolt 16. An elastic body 18 made of rubber is interposed between the above two brackets, and a fluid chamber 23 is firmed inside the elastic body 18, while a band 24 serving as an outside force applying means is wound round the outer periphery of the central part of the elastic body 18. By engaging the fastener 26 of the band 24 selectively with any one of engagement holes 25a, 25b... the central part of the elastic body 18 can be narrowed down arbitrarily. Thereby the internal pressure of the elastic body 18 is changed, and thus the supporting characteristics thereof can be changed.

Title: Method and device for determining blood cell
Inventor: HARA SHINJI
IPC: G01N33/49
Filed: 1984-02-23
Abstract: PURPOSE:To decide easily a health condition from a slight amt. of a blood by measuring the void generating rate of blood cells from the magnified image of the uniform agglutinated film of the blood. CONSTITUTION:A fresh blood B is first squeezed from the finger, etc. to a spherical shape and is stuck gently to the marked region 2 on slide glass 1, thus forming an agglutinated film. The slide glass 1 having such agglutinated film is imposed on a blood cell discriminator and light is irradiated from a light source 3 provided in the lower part thereof and at the same time the agglutinated film on the glass is magnified to about 200-400 times by an optical magnifying device 4 provided above said glass. The magnified image is converted to a video signal by a video camera 5 and further the video signal is inputted to a microcomputer 6 which divides the video image to for example, 319X199 segments and displays the generating condition of voids in the agglutinated films in the respective segments on a video monitor 7. The health condition is thus easily decided by observing the condition how the voids are generated on the agglutinated film.

Title: Pasty solder
Inventor: NAOI MASAYA
IPC: B23K35/22
Filed: 1989-02-10
Abstract: PURPOSE:To prevent a Manhattan phenomenon by using the pasty solder which is formed by mixing at least two kinds of solder particles of different m. p. and selecting the average grain sizes of the solder particles having the high m.p. so as to be larger than the average grain size of the solder particles having the low m. p. CONSTITUTION:Surface-packaging parts 1 are joined by the pasty solder 10, 11 onto conductive layers 6, 7 formed on a printed circuit board 5, by which reflow soldering is executed. The solder formed by the low melting solder particles 10a and the high melting solder particles 10b heats up gradually and the surface packaging parts 1 are first lightly joined to the conductive layers 6, 7 by the low melting solder 10a of the small grain size. The effect of the surface tension is small and, therefore, the Manhattan phenomenon does not arise even if only the one side is heated up to a high temp. and is melted. The high melting solder particles 10b melts when the temp. rises higher. The other side is lightly joined by the low melting solder particles 11a and, therefore, the surface packaging parts 1 do not rise even if only the one side heats up to the high temp.

Abstract: PURPOSE:To detect specific pressure automatically by providing one or plural sensors at the outer periphery of a dial and allowing the tip of a pointer to pass through the sensors. CONSTITUTION:The pointer moves according to the pressure of gas or fluid and its tip part is so extended as to pass through sensors 8. The sensors 8 use, for example, a photosensor and are formed in a U side-face shape so that the tip part 11 of the pointer 6 passes through their intermediate parts; a light emission part 12a such as a light emitting diode is provided at one side and a photodetection part 12b such as a phototransistor is provided at the other side. Therefore, when the tip part 11 of the pointer 6 passes through one sensor 8, light traveling from the projection part 12a to the photodetection part 12b is cut off and the passing of the pointer 6 is detected, so that the sensor 8 sends out a detection signal of specific pressure. Further, the pressure to be detected is varied possibly, so the sensors 8 can be shifted in fitting position at the outer periphery of the dial 7.

Abstract: PURPOSE:To dispense with an operation state setting means in an addition apparatus and to reduce the difficulty in a mounting by adding the operation state setting function of the addition apparatus to the operation state setting means of a printer itself and holding the set content thereof. CONSTITUTION:When an addition apparatus is connected or the connection thereof is estimated, an operation state setting circuit 1, for example, an operation panel is set to an operation state or a dip switch is set to a specific state when a power supply is closed. Whereupon, according to the content thereof, the kind and operation state of the addition apparatus 5 are judged by a printer control circuit 3 to be stored in a memory circuit 2. Next, in order to prescribe the operation of a printer 7 itself after the power supply is opened, the state of the dip switch is altered and the power supply is closed without operating the operation panel. At this time, the printer control circuit 3 judges the state of the dip switch as the operation state of the printer 7 itself to prescribe the operation state of the printer 7 itself. The data related to the addition apparatus 5 stored in the memory circuit 2 is transmitted to the addition apparatus 5 at the point of time when the addition apparatus 5 is actually connected and required by the printer control circuit 3.

Abstract: PURPOSE: To decrease the input current peak value at operation start and avoid power voltage breakdown by stopping a converter until the power voltage at power input becomes high to some extent.  
     CONSTITUTION: When power voltage Vcc is lower than the preset value, operation stop signals are fed to the inhibit terminal INH and when higher, the control circuit CNT to operate the converter CNV is provided. By stopping the converter until power voltage becomes high to some extent, the input current peak value at power input decreases and the breakdown of rhe power voltage Vcc is avoided. By exchanging the constant voltage diode ZD, the converter operation start voltage and its period are arbitrarily assigned. Also by setting the reference voltage fixed by this diode nearly in the reference value of power voltage, the surge current at operation start can be reduced almost to the degree of steady current.
