Filed: 1998-03-03
Abstract: PROBLEM TO BE SOLVED: To perform the sticking of a liquid crystal panel while the accurate positioning is performed by putting a free cell to be stuck into a container and vacuum-packing it. SOLUTION: The one (free cell) (a) for which an array substrate and a color filter substrate are aligned and temporarily fixed is put in a metallic frame (b) and put in a poly bag (f) and it is put in a vacuum chamber and vacuum packed by using a seal heater. Thereafter, when it is taken out from the vacuum chamber and an atmospheric pressure is applied, a pressure is applied through the plastic bag (f) to the free cell (a) and a prescribed clearance is formed between the both substrates. In this case, since the metallic frame (b) is present, force for shifting the both substrates does not act. In the state, thermosetting is performed in the atmospheric pressure and after the setting is ended, the plastic bag (f) is opened.  In such a manner, heating is performed without generating the disorder of the alignment of the both substrates, a thermosetting adhesive material is cured and the both substrates are stuck.

Title: Method of surface treatment for imparting hydrophilicity to aluminum material
Inventor: SHIMADA KAORU
IPC: C09D5/14
Filed: 1993-03-11
Abstract: PURPOSE:To form a coating film excellent in hydrophilicity on the surface of metallic material comprising, e.g. aluminum. CONSTITUTION:A surface treatment for rendering metallic material hydrophilic which is basically composed of a water-soluble resin, colloidal silica, a crosslinking agent and a water-soluble carbonate and which has a viscosity adjusted, if necessary, to make it suitable for the application form by incorporating a thickening agent therein. A hydrophilic coating film is formed by degreasing the surface of an aluminum material, drying it, coating it with the surface treatment, and then drying it by heating. When the surface of aluminum material is treated with an aqueous solution of a water-soluble carbonate or of a surfactant after film forming, the hydrophilicity is further improved. The metallic material having enhanced hydrophilicity can prevent the residence of condensed water as large droplets on the surface and is therefore used, for example, as a fin material, etc., assembled with narrow gaps in order to increase heat exchange capacity.

Title: Timing generator
Inventor: GOTO MASAHARU
IPC: H03K5/13
Filed: 1991-02-22
Abstract: PURPOSE:To offer a timing generator which never causes dead time and besides, can change timing at any time. CONSTITUTION:A coarse timing pulse generating means (counter) 1 generates a coarse timing pulse for a desired timing by specifying properly an input clock pulse, and a timing vernier 2 generates a close timing pulse by delaying properly this coarse timing pulse. In a compensation circuit 4, the close timing pulse is inputted to a one-input plural-output delay circuit 41, and the output from its plural delayed outputs is selected by a multiplexer 42. Thus, while the multiplexer 42 outputs the output whose delay time is other than '0', the compensation circuit 4 can input the next pulse from the timing vernier 2, and the dead time is never caused.

Title: Thermal head
Inventor: MINAMI KEIJIRO
IPC: B41J2/355
Filed: 1985-03-14
Abstract: PURPOSE:To suppress occurrence of surge by limiting a drive switching time of a driver IC element. CONSTITUTION:Driver IC elements 3 are connected with individual drive signal lines 4, common drive signal lines 6 and, in addition, control signal lines 7, too; and through the control signal lines 7 image signals are put in. The drive switching of of output transistors Tr1, Tr2... of the driver IC elements 3 is controlled by the above image signals, and heat generating resistors 2 selectively generate heat. And with this heat, color development is caused to occur on a heat sensitive recording paper which moves in contact with a thermal head, and printing is carried out. A surge occurrence has an inseparable relationship with switching time of the driver IC elements, and the longer the switching time gets, the less the occurrence of surge takes place, and even if a surge is generated the voltage becomes lower. In view of this, if a switching time of the drive IC elements is limited within a scope of 100-300n sec, generation of surge voltage is wiped out, and even if it should occur, the voltage may be much reduced.

Abstract: PURPOSE:To take a high-precision measurement without depending upon the set gain and sensitivity of a flaw detector by estimating the sectional size of a defect part on the basis of the propagation time of an ultrasonic wave. CONSTITUTION:A transducer 1 for ultrasonic wave transmission and transducers 2 and 3 for reception are arranged at specific intervals and scanned along an object 4 to be measured while contacting the surface 4a of the object 4.
