Title: Ink jet recorder
Inventor: MARUYAMA MITSUAKI
IPC: B41J2/20
Filed: 1980-12-04
Abstract: PURPOSE:To prevent the stuffing of fine dust into nozzle by a cleaning mechanism by cleaning the frontal side of the head while pushing out ink from the nozzle during the cleaning period. CONSTITUTION:A cleaning means 17 made of a rubber material, etc., is closely adhered to the frontal side of a nozzle 23 during the period when recording is stopped and is therefore capable of serving as a cover to prevent the clogging of the nozzle due to the drying of ink. The cleaning means used is of a rotary type having a notched portion, for example. When starting a recording, a pump 12 is turned while the cleaning means 17 is closely adhered to the nozzle. Under a condition that a valve 14 is usually opened, ink is circulated between the head and an ink tank, during which period bubbles are removed. Afterwards, the cleaning means is turned and the frontal side of the head is cleaned.

Title: Ankle joint device for artificial leg
Inventor: AOYAMA TAKASHI
IPC: A61F2/50
Filed: 1997-06-12
Abstract: PROBLEM TO BE SOLVED: To provide an ankle joint device for an artificial leg which can facilitate the walk of the artificial leg user by increasing the angle of backward bending while the legs are at loose position. SOLUTION: A second shank 32b of an eccentric shaft 32 is displaced toward the heel side past a first shank 32a during backward bending in a standing-leg phase, and thereby the support frame 26c of an under-foot bearing 26 supported against a first shank 32a is moved toward the heel. Accordingly, the backward bending angle of an above-foot bearing 30 connected to the support frame 26c via a slide shaft 36 increases. Subsequent to the backward bending, a foot joint device 20 is raised and shifts to a loose-leg phase, during which the backward bending angle is maintained, i.e., the tip of the foot part is held raised, whereby the walk of an artificial leg user can be facilitated.

Title: Flow control valve
Inventor: SHIRAI SHIGERU
IPC: F16K31/06
Filed: 1979-12-28
Abstract: PURPOSE: To lessen the scattering of valve performance, by applying an interaction of both leaf and coil springs to a plunger that actuates a valve.  
     CONSTITUTION: When a electric current flows in a solenoid coil 58, electromagnetic force is generated to cause an action for depressing a plunger 57 downward, and pressure P 2  of fluid flowing out from an outlet 52 is determined by the force applied to a valve body 55 from the theory of governor. That is, the value of an electric current flowing in the solenoid coil 58 can optionally change the pressure P 2  to a certain range. In the present invention, the scattering of valve characteristic can be lessened because small tension of leaf springs 61, 62 with wide scattering of their spring constant and large tension of a coil spring 70 with narrow scattering of its spring constant are applied. While the limitation of a valve stroke in accordance with allowable stress of the leaf spring can be also eased because its tension is distributed to the coil spring, thus to obtain a large stroke.

Title: Ceramic heater
Inventor: SATO SHIGEHIRO
IPC: H05B3/14
Filed: 1991-07-12
Abstract: PURPOSE:To stand long service as well as to prevent the occurrence of break away by making up an electrode of a connecting section which is directly overlapped on the surface of a heater end section, and of a power receiving section on the surface of a substrate while electrically being connected to the connecting section. CONSTITUTION:In a heater 2 made out of a membrane body made. of a silver palladium alloy, both the end sections 22 of a heating section 21 roughly 270mm long and roughly 4mm wide are widened to the full width of a substrate 1 while being extended to 3mm. An electrode 3 is made of the membrane body of silver, and is made up of a connecting section 31 which is closely adhered and overlapped on the whole surface of each end section 22, and of an initial power receiving section 32 which is directly formed on the surface of the substrate 1 to the full width while being continued to the connecting section. The exposed surface of the substrate 1 including the surface of the heater 2 is covered with a protective film 4, and the end section ranging from the whole surface of the connecting section 31 to a boundary section with the initial power receiving section 32 is also covered with the film. This constitution thereby does not allow metals contained in the heater 2 to be immersed into the initial power receiving section 32 so as to be increased in electrical resistance, but allows the receiving section to be prevented from being deteriorated even if the initial power receiving section 32 is heated by means of energizing, the receiving section will therefore never be broken away even if it is used for a long time.

Title: Method and apparatus for measuring coersive force
Inventor: KATO TOSHIHIRO
IPC: G01R33/14
Filed: 1984-08-18
Abstract: PURPOSE:To enable the measurement of coersive force of a test piece simply and in a short time, by cancelling the residual magnetism of a test piece by a magnetic field generated with a demagnetizing coil to detect it with a Hall element as opposed to the test piece. CONSTITUTION:A test piece holder 44 is set at a desired position as opposed to a Hall element 55 for detecting the magnetic field of a test piece and DC excitation current is allowed to flow to a magnetizing coil 11 from a DC voltage varying circuit 21 to magnetically saturate the test piece 46 by magnetization. Then, the excitation current fed to a demagnetizing coil 12 from a DC voltage varying circuit 22 is increased sequentially to generate a magnetic field in the direction opposite to that of a magnetic field of the magnetizing coil 11. Then, the difference in the output between a Hall element 55 for detecting the magnetic field of a test piece and a Hall element 56 for detecting a magnetic field in a hollow is monitored with an X-Y recorder 30. In this manner, the coersive force of the test piece 46 is calculated from the excitation current when the difference in the output between Hall elements 55 and 56 becomes zero as the test piece 46 loses the holding force with an increase in the excitation current.

Title: Manufacture of base material for optical fiber
Inventor: IMOTO KATSUYUKI
IPC: C03B37/018
Filed: 1980-12-08
Abstract: PURPOSE:To make the flame state of a burner independent of the internal pressure of a reactor by specifying the ratios of the cross-sectional area of the reactor to that of a gaseous flow spouted from the nozzle of the burner and that of a glass base material, and the position of an exhaust port in a vapor axial deposition method. CONSTITUTION:A reactor 6 having diameter Dh is made >=25 times as large as a gaseous flow having diameter Dn spouted from the nozzle of a burner 1 in cross-sectional area and >=4 times as large as a porous glass base material 2 having diameter Ds in cross-sectional area. An exhaust port is attached to the side of the reactor 6 at a position (yA) >=15 Dn away from the nozzle in the flowing direction of the gaseous flow. Thus, changes in the temp. distribution of a flame 5 within a cross section and in the extent of the temp. fluctuation are inhibited, and the flame 5 is hardly changed even if the internal pressure of the reactor 6 is made uneven to some degree. Accordingly, a change in the refractive index distribution of the resulting optical fiber in the axial direction is almost prevented, and unevenness in the zone characteristics is reduced.
