Patent JP-H05302693-A (JP)
Title: Pipe joint
Inventor: YAMAMOTO YUJI
IPC: F16L43/00
Filed: 1992-04-24
Abstract: PURPOSE:To reduce a muck dropping noise by forming a joint inner wall surface layer, in a part on which a connection port inside cross sectional shape is projected when parallel light is radiated to the central axis of the pipe connecting port, of an elastic material having specific hardness and thickness in a pipe joint having a bend pipe part. CONSTITUTION:A joint body 2 is formed of cast iron, and has a bend pipe part 23 between a vertical pipe connecting port 21 and a horizontal pipe connecting port 22, and the wall surface of the bend pipe part 23 on which an inside cross sectional shape of the vertical pipe connecting port 21 is projected when parallel light is radiated to the central axis of the connecting port 21, is swollen outside of a pipe, and a recessed part 24 is formed inside of it. An elastic material layer 3, whose surface layer has Shore D hardness equal to or lower than 50 degree and thickness equal to or thicker than 5 millimeter, is formed in this part. Since a part of muck dropping energy is absorbed by the elastic material layer 3, vibration is reduced in a joint part, so that a generating noise can be also reduced. It is preferable to set the elastic material layer 3 surface and the other part surface on the same plane. Natural rubber, synthetic rubber, a synthetic resin elastomer material or their foaming body can be listed as a construction material for an elastic materal.

Title: Method and apparatus for casting
Inventor: SATO MINORU
IPC: B22D18/04
Filed: 1988-04-28
Abstract: PURPOSE:To shorten cycle time and to enable stable casting by starting pressurization at pressure in a pressure vessel at furnace side higher than pressure in a pressure vessel at die side, casting molten metal in the furnace into the die and specifying the upper limit of pressure difference between both pressures. CONSTITUTION:The dies 2, 3 to the pressure vessel 4 and the holding furnace 6 to the pressure vessel 7 are set, respectively and closed with hydraulic cylinders 8. 9. Successively, high pressure gas is introduced from supply holes 11, 12 to pressurize the both pressure vessels 4, 7 to the atmospheric pressure or more. Then, the pressure in the pressure vessel 7 at the furnace side is started to be pressurized so as to come to higher than the pressure of the pressure vessel 4 at the die side. By this pressure difference, the molten metal in the furnace 6 is cast into a product part 1 in the die through a stoke 5 communicating the furnace 6 with the dies 2, 3. Further, the upper limit of the above pressure difference is made to 0.5-30% of the holding pressure in the pressure vessel 4 at the die side. When the pressure in the pressure vessel 4 at the die side is at 3-7kgf/cm<2> or 7-30kgf/cm<2>, the above pressure difference is desirable to be made 3-30% or 0.5-10% of the above pressure, respectively.

Filed: 1978-08-30
Abstract: PURPOSE: To realize improvement in precision and fast character recognition by providing the pen of a handwitten-character input unit itself with a function of moving-direction detection.  
     CONSTITUTION: Rotary disc 13 centering on axis 12 of pen 1 is provided with one window 14 in its radius direction. Once tip axis 12 of pen 1 starts drawing curve M, paper surfaces 2 is irradiated with light from light source 18 and reflection signal of a character stroke strikes rotary disc 13 through window 14, so that the direction of the character direction can be detected. Since the quantity of reflected light decreased when light reflected from the calligraphic curve M passed through window 14 provided to rotary disc 13, a constant supervision over the rotation angle of motor 15 turing rotary disc 14 is exercised so as to make it possible to detect at any time the segment direction (the moving direction of the pen) of the character stroke judging from the rotation angle when the quantity of the reflected light decreases.

Abstract: PURPOSE:To prevent the record of information from being missed at the time of switching a mode to a recording mode, by setting reference DC power levels equal both in a recording and a reproducing modes, and obtaining a feedback signal by peak holding when information of rectangular waveform shape is superposed on a monitor current signal. CONSTITUTION:A current comparison circuit 5 compares the monitor current signal iM photoelectric-transduced by a photodiode 4 with a reference current from a constant current source 15, and supplies a comparison differential signal SUB to a peak holding circuit 16. The circuit 16 holds the upper limit or the lower limit level of the signal SUB, and supplies it to a current driver circuit 11. By constituting a device in such a way, the signals iM and SUB are formed in the rectangular waveforms corresponding to the information, however, a signal PH is constant in spite of the mode, and a current on a laser diode 2 remains unchanged. Therefore, no change occurs in a DC level at the time of switching the mode to the recording mode, therefore, no missing of the information is generated.
