Title: Water heater by midnight electric power
Inventor: HORIUCHI TOSHIHIRO
IPC: F24H1/18
Filed: 1986-09-19
Abstract: PURPOSE:To make it possible to obtain hot water at a set temperature when the midnight electric power supply time band ends by turning ON the electric power supply to a heat generating body again when the temperature of hot water drops after it reached a set temperature and when the electric power supply stops during the midnight electric power supply time band turning ON the electric power supply to a heat generating body when the electric power supply is resumed. CONSTITUTION:Water temperature Tw detected by a water temperature sensor 3 is inputted through a water temperature detection circuit 4 and a hot water temperature Ts detected by a temperature regulating volume 5 is inputted through a set hot water temperature detection circuit 6. The hot water temperature set value is provided with a certain operation differential alpha, and when the water temperature Tw reaches a set value Ts once and after that the water temperature Tw drops lower than the temperature Ts-alpha, the electric power is supplied again to a heater 9. With this arrangement during midnight electric power supply time it is possible to maintain the water temperature Tw at near the set hot water temperature Ts, and for power failure during the midnight electric power supply time it is also possible to avoid the operation where the hot water is not being boiled due to time shortage because the electric power is supplied to the heater without a delay timer.

Title: Method and apparatus for forming film of liquid crystal display element
Inventor: KAMEI HIROKAZU
IPC: G09F9/30
Filed: 1989-08-30
Abstract: PURPOSE:To uniformly form an insulating film on a substrate by dipping the substrate into a film forming liquid tank, then discharging the film forming liquid from the film forming liquid tank. CONSTITUTION:The top end side of the substrate 2 is pinched by a pinching jig 4 are a dipping motor 10 is run to dip the substrate 2 into the film forming liquid 3. The edge part at the bottom end is fixed by a V receiving jig 8 while the substrate 2 is held dipped. A motor 11 for controlling a discharge valve is controlled to regulate the discharge valve 6 and to discharge the film forming liquid 3 when the lapse of the specified time after the dipping is judged. The exposing of the substrate 2 to the outside of the film forming liquid is, therefore, possible even if the substrate 2 is not moved. The insulating film is thus formed without oscillation of the substrate 2. The uniform formation of the insulating film is possible in this way even if the substrate 2 is large in area.

Abstract: PROBLEM TO BE SOLVED: To control registration quantity accurately, by correcting drafting parameters so that a second distorsion can be substantially equal to a first distorsion. SOLUTION: A first to third pattern are formed on a photomask substrate and patterns serving as references are each formed into a grid. The first pattern being scanned by a light beam and scattered light from pattern edges being detected, measured lattice point coordinates (Xi, Yj) are found. Similarly, measured lattice point coordinates (Pi, Qj) are found as to the second pattern, and differences between Xi and Pi and between Yj and Qj are found, which are taken as a first distorsion. Nextly, measured lattice point coordinates (Si, Tj) are found similarly as to the third pattern, and differences between Xi and Si and between Yj and Tj are found, which are taken as a second distorsion. In order to correct photomask drafting which serves as a mother, the second distorsion is caused to be substantially equal to the first distorsion.  That is, drafting parameters are properly corrected by using a correction value found from a difference between the first distorsion and the second distorsion.
