Title: Liquid crystal display element
Inventor: TSUCHIYA YUTAKA
IPC: G02F1/1365
Filed: 1995-02-07
Abstract: PURPOSE: To make it possible to control light absorption without depending on the dyestuff in liquid crystals and light molecules, to enhance reliability to light and to make display with good visibility by forming a light absorption layer on an electrode surface. CONSTITUTION: The reflection electrode 108 is formed by sputtering Cr and patterning its film on a lower substrate 109 of a liquid crystal display element. The light absorption layer 107 is formed by spin coating the organic resist on the front surface of the reflection electrode 108. Transparent electrodes 102 are formed by ITO on an upper substrate 101. The liquid crystals 105 are injected between the substrates formed in such a manner, by which the liquid crystal display panel is formed. Black display is obtd. with this panel by absorption of the light absorption layer 107 when voltage is off. The liquid crystals 105 orient in an electric field direction and generate the discontinuous points of the refractive index within the medium when the sufficient voltage is impressed thereon and, therefore, a light scattering state is attained.  Consequently, the light scattering layer is formed just before the light absorption layer 107 and, therefore, the white display is obtd.

Title: Gas laser oscillation apparatus
Inventor: TAKAGI SHIGEYUKI
IPC: H01S3/036
Filed: 1990-01-31
Abstract: PURPOSE:To obtain a smooth gas flow speed by a method wherein individual side faces on the side of a main discharge space part are arranged on nearly the same face and are formed on the face which regulates the flow of a gas laser medium. CONSTITUTION:Peaking capacitors (15) of a nearly rectangular parallelepiped are arranged. The peaking capacitors (15) are formed on slopes (16) in such a way that one face of a hexahedron becomes a regulating face of the flow of a gas laser medium. Since the peaking capacitors (15) come into contact with each other and the slopes (16) are arranged to be nearly the same face, the slopes act in the same manner as a wind guide (10) and regulates the flow of the gas laser medium; the medium flows into a main discharge space. Since the slope (16) of the peaking capacitor (15) on the downstream side is directed to the diverging direction, the gas laser medium which has flowed into is discharged quickly from the main discharge space (4).

Title: Manufacture of spherical slide bushing
Inventor: ITO MIKIO
IPC: F16C11/06
Filed: 1991-01-18
Abstract: PURPOSE:To obtain a manufacturing method of a spherical slide bushing which can always give guarantee of excellent operation even if components have a certain extent of errors in manufacturing. CONSTITUTION:An insert 4A and an external barrel 2A are pressed in the lower end opening of a barrel-like holding member 1 beforehand. An internal barrel 3 is inserted into the upper end opening to force a spherical swelling section 31 to about the recessed face 41 of the insert 4A and is made to rotate by means of a rotary drive shaft 91 inserted into and fixed in the internal barrel 3. An insert 4B and an external barrel 2B are gradually pressed in the upper opening of a holding member 1 to force the recessed face 41 of the insert 4B to abut the external periphery of the swelling section 31 so that the torque of the rotary drive shaft 91 after the abutting may be detected by a torque detector 6 and the abovementioned press-in process is stopped when the torque reaches the specified value. Since the torque of the rotary drive shaft 91 varies according to the variation of the contact pressure between the recessed face 41 and swelling section 31, if the press-in process is stopped at a position where the above torque indicates a proper value, proper contact pressure can be realized regardless of errors in manufacture of the inserts 4A and 4B and internal barrel 3 and excellent operation can be realized.

Title: Mig arc welding method
Inventor: AKUSA KAZUO
IPC: B23K9/16
Filed: 1980-02-22
Abstract: PURPOSE: To generate arc in a low current region stably by performing pure inert gas shielded MIG arc welding by the use of DC current superposed with pulse current and the use of a welding wire added with rare earth elements.  
     CONSTITUTION: MIG arc welding is performed in an inert gas (e.g.; pure Ar gas) not added with any active gas by using a wire added with rare earth elements (e.g.; Ce) of the amount occupying 0.02W0.30wt% in the welding wire. In this case, the  DC current superposed with pulse current of 25W500Hz is used as te essential requirement. Conditions are so set that the mean current comes in a small current  region of about ≤220A by selecting the frequencies of the pulse current and the  combinations of maximum and small current values. As a result, the amount of  wire melting decreases in proportion to the mean current and therefore an adequate  amount of wire melting is obtained; at the same time, the solidifying of molten metal progresses rapidly at the minimum current time of pulse waves; hence, even in a  vertical or horizontal position, the drooping of the molten metal does not occur,  thus all position welding is performed without any problem.
