Title: Inkjet recording method and its apparatus
Inventor: SUGA MICHIHISA
IPC: B41J2/14
Filed: 1983-08-31
Abstract: PURPOSE:To enable the jetting of fine ink drips by forming an air current toward a recording paper in the perimeter of a nozzle orifice with a thin wall so that the viscosity resistance due to the air current works on an ink extruded from the nozzle orifice under a pressure along the direction of the air current. CONSTITUTION:An orifice 110 of a nozzle 102 is formed extremely thin so as not to exceed 1.5 in the ratio of the outer diameter to the inner diameter of an orifice section and air current flows evenly without generating a large turbulence in the perimeter of the orifice 110 and an ink meniscus 113. As a result, the extrusion of the ink meniscus 113 can be always done stably by a pulse pressure to form a stable ink drip. Since the ink meniscus 113 being extruded receives a force in the direction of being torn from the orifice 110 by a viscosity resistance due to the ambient air current, it flies in ink drips on the air current even when it has not a kinetic energy enough to separate from the orifice 110.

Title: Bearing device of rotary machine for vehicle
Inventor: YAGI NOBUYUKI
IPC: F16C33/76
Filed: 1982-09-14
Abstract: PURPOSE:To maintain for a long period of time the external air cutting off operation and prevent fouling and deterioration of bearing lubricating grease by forming an annular groove in which sealing grease is filled in the internal peripheral member of a stator member and a sealing agent filling chamber at the outer part of the annular groove. CONSTITUTION:External air which is going to flow into a machine through a minute gap (g) is cut off by a sealing agent W within the annular groove 22, and hence the external air is prevented from flowing into the machine. When the machine is continuously used for a long period of time, the sealing agent W within the annular groove 22 is affected by a rotating collar 9 and escapes into the minute gap (g) gradually vanishes, whereas the sealing agent W filled within the sealing agent filling chamber flows down and replenished, and the external air cut-off effect is maintained. With the advance of the replenishment and supply of the sealing agent W, a space occurs at the upper part of the sealing agent filling chamber 23. However, since the sealing agent filling chamber 23 is hermetically closed, the external air cut-off operation is not impaired.

Title: Communication system interconnecting terminal equipment
Inventor: AIZAWA HIROO
IPC: H04M3/00
Filed: 1990-06-20
Abstract: PURPOSE:To prevent illegal use of a private line by registering identification information of a terminal equipment to which the use of the private line is to be allowed in advance and permitting the use of the private line when the identification information sent at the arrival of a call is registered. CONSTITUTION:When a call comes from a terminal equipment 1 with identification information registered in advance thereto to a transmitter-receiver 2, a switch section 21 is closed and an opposite transmitter-receiver 4 is called via a private line 5. The transmitter-receiver 4 makes dialing to an ISDN network 200 accordingly. As a result a caller terminal equipment 1 connects to the ISDN network to which an object called terminal equipment belongs and receives an incoming address of an object terminal equipment 3 to call the opposite terminal equipment. Moreover, when a call comes from the terminal equipment whose use of the private line 5 is not permitted to the transmitter-receiver 2, the call is not registered in a registration means 51, resulting that the line interrupt procedure is taken. Thus, illegal use of the private line 5 is prevented.

Title: Driving method of semiconductor laser
Inventor: KURATA YUKIO
IPC: H01S5/042
Filed: 1980-11-12
Abstract: PURPOSE:To drive a laser in a high SN ratio by a method wherein by a driving current of a semiconductor laser being superposed and a noise component of an output light being modulated and detected, a driving current value is controlled so that a mode distribution noise may take a minimum level. CONSTITUTION:An output light of a semiconductor laser is radiated on an optical system 7 and a sensor 2. A signal is applied on a BPF3 from the detector 2 in accordance with a variation of output intensity. After a driving current of the laser 1 is set at a working state, a very low AC signal of which the frequency is far from a frequency band necessary for the optical system 7 is superposed on the driving current, a noise component of the output light of the laser 1 is converted into an electrical signal by a photo sensor 2 and detected 4 through the BPF3, a modulated noise component is taken out, and phase sensitive detection 5 between it and modulating frequency is performed. By detecting at which side of a noise peak the established driving current appears, a feedback to a driving circuit 6 is performed. By this constitution a laser having single mode oscillation originally of low noise nature is operated at a high SN ratio without any increase in mode distribution noise due to mode transition.

Title: Position detecting method for scribing line crossing area
Inventor: SAIDA MASAKAZU
IPC: G06T7/00
Filed: 1990-06-19
Abstract: PURPOSE:To enable position detection for a variety of substrates by regarding a coordinate position, based upon coordinate values of two integral values which are judged to match scribing line widths in an X and a Y direction, as the position of the angle in the crossing area of the scribing lines. CONSTITUTION:An enlarged gradational image of the scribing line crossing area of a substrate W which is picked up by a television camera 6 is inputted to an image processing unit 7. The image which is inputted to the unit 7 is an image which is photographed through a downward lighting microscopy opti cal system, so the gradation value of the edges of the scribing lines on the substrate W is small. Then the edges of the scribing lines slant to the substrate surface because of a step due to the high-low difference between the areas of the scribing lines on the substrate surface and a pattern area. Therefore, light which is projected from an objective 2 and irradiates the substrate W is reflected off the entrance pupil of the lens 2, so that the light does not reach the camera 6.
