Title: Liquid crystal display element and its production
Inventor: KASHIWAGI TAKAFUMI
IPC: G02F1/1339
Filed: 1992-11-17
Abstract: PURPOSE:To increase the yield of production stages and to obtain high reliability by hermetically holding spacers and a liquid crystal between plural substrates and setting the diameter of the spacers larger than the thickness of a liquid crystal layer. CONSTITUTION:One of two sheets of glass substrates 1 is spin coated with a transparent acrylic resin of a UV curing type and thereafter, the entire surface is irradiated with UV rays and is cured to obtain a soft film 7. Transparent electrodes 3 are then formed on the surface of the formed film 7 and the surface of the other substrate and are patterned as needed. The film 7 is subjected to a rubbing treatment, by which a liquid crystal oriented film 4 is obtd. The two substrates 1 are stuck to each other and after a sealing material 2 is cured, the substrates 1 are cut to a prescribed shape, by which an empty cell is obtd. A liquid crystal 6 is filled into the cell by an atm. pressure difference. The excess liquid crystal is discharged and the spacers 5 are penetrated into the film 7 by using a jig in such a case. Since the diameter of the spacers 5 is larger than the thickness of the liquid crystal layer, the spacers 5 partly penetrate the soft film 7 on the substrate 1.

Title: Pellicle frame for protecting ic reticule
Inventor: NAGASHIMA SHIRO
IPC: G03F1/64
Filed: 1989-11-27
Abstract: PURPOSE:To prevent the sticking of the foreign matter peeling from a pellicle to a reticule by forming the sides of a square frame of members having air permeability to the air in the pellicle frame and applying a tacky adhesive agent which captures the dust suspended in the pellicle frame on the inside surface of the other peripheral members. CONSTITUTION:The pellicle frame 2 is formed of the square frame 2a and the proper tacky adhesive agent 4 is applied on the inside surface of the members 2a-1, 2a-2 on the adjacent two sides thereof. Since the tacky adhesive agent 4 sticks the extremely light foreign matter, such as dust, the tacky adhesive agent of slight tacky adhesive strength suffices. The tacky adhesive agent having the high tacky adhesive strength hinders the extending operation of the pellicle 2b or the like and is, therefore, undesirable. Plural very small through-holes (q) are provided in the members 2a-3, 2a-4 of the two sides of the frame 2a to allow the transmission of the air. The members 2a-3, 2a-4 are otherwise formed of a porous sintered alloy or sintered ceramics to allow the transmission of the air A by the air permeability thereof. The foreign matter sticking or suspending in the pellicle frame is captured in this way and the contamination of the reticule is prevented.

Title: Manufacture of grain-oriented silicon steel sheet
Inventor: KAMI TSUTOMU
IPC: C21D9/46
Filed: 1997-11-10
Abstract: PROBLEM TO BE SOLVED: To improve the uniformity and adhesivity of a film over the whole width and the whole length of a coil, and to improve the magnetic characteristic by controlling the adhesion of a Si compound to a surface of a steel sheet before decarburizing- annealing according to the ratio of the Si concentration of the surface oxide to the Si concentration of base iron on a surface layer of the steel sheet after the intermediate annealing. SOLUTION: As the ratio of the surface Si concentration to the Si concentration of a base iron of an intermediately annealed sheet obtained from the Si profile by the glow discharge spectral analysis, i.e., the ratio of the surface Si integrated intensity to the Si integrated intensity of the base iron becomes the higher, the quantity of the Si compound before decarburizing-annealing is increased, and the oxygen quantity of a decarburizing-annealed sheet is increased. Based on this fact, the oxygen quantity of the decarburizing-annealed sheet is measured, and it is judged whether the quantity is within the control range, and the appropriate Si adhesion quantity is reviewed from the relationship between the annealing atmosphere and the Si adhesion quantity on the steel sheet surface.  The feedback control is achieved so as to regulate the electrolytic degreasing electricity of a next coil. The oxygen quantity after the decarburizing-annealing can be controlled with excellent accuracy.

Abstract: PROBLEM TO BE SOLVED: To inhibit a residual water in a heat exchanger from turning in a super heated state and prevent the generation of a post boiling phenomenon by providing a time lag timer which starts when generating a hot water supply stop command signal and closing a water valve when this time lag timer is timed up. SOLUTION: In the case where a gas burner B is adapted to maintain a combustion state and continues supply of hot water in a small-sized hot water heater, if a hot water supply stop command signal is output by turning on an operation switch 10 once again or if a thermocouple detects a blowing out of flames, the supply of power to a holding coil is halted with a control circuit C, thereby closing a gas valve 30 so that the gas burner B may be extinguished. And at that time, about 0.6 seconds time wait of the time lag timer is executed, and then a water valve 20 is closed.  This construction makes it possible to allow water to flow in a water circuit 2 of the heat exchanger 36 area for some time even after the gas burner is extinguished and rob of the heat inertia of the construction wall of the heat exchanger 36 with the water, thereby contriving to prevent the generation of a post boiling up.
