Title: Undervoltage protection system
Inventor: MAKABE MATAAKI
IPC: H02H3/05
Filed: 1995-03-24
Abstract: PURPOSE: To obtain an undervoltage protection system for enhancing the reliability in the protection of power system by monitoring the unnecessary function of an undervoltage relay provided for a power system thereby preventing a circuit breaker from being tripped and opened due to erroneous function thereof. CONSTITUTION: The inventive system comprises a no-voltage detection means connected with an instrument transformer 7 which is connected with a first undervoltage relay 20, and a second undervoltge relay 25 connected with an instrument transformer different from the instrument transformer 7. The second undervoltage relay 25 has a set voltage equal to or higher than that of the first undervoltage relay 20. When the first undervoltage relay 20 functions, a circuit breaker 2 is tripped and opened on condition that the no-voltage detection means does not function or the second undervoltage relay 25 functions.

Title: Drive system for oscillatory-wave motor
Inventor: OKUMURA ICHIRO
IPC: H02N2/00
Filed: 1986-04-21
Abstract: PURPOSE:To remove an output difference dependent upon a direction of rotation by changing a phase difference between an output AC voltage and a driving voltage of an oscillation-detecting electrode to a proper quantity according to the direction of rotation of an oscillatory-wave motor. CONSTITUTION:A diaphragm is provided with A phase driving electrodes A1-A5, B phase driving electrodes B1-B5 and an oscillation-detecting electrode S and piezoelectric elements of these portions are polarization-treated appropriately. Then, a phase difference between an AC voltage applied between these driving electrodes and that detected by the detecting electrode S is varied by  phi according to a direction of rotation of a motor. For example, if the detecting electrode S is arranged at the distance theta =315 deg. from the driving electrode A5, a phase difference variation  phi should be 90 deg. in order that the diaphragm is placed in the same oscillatory state according to the direction of rotation. As a result, the motor can be driven always at a frequency fr (the mechanical resonance point of an oscillatorywave motor) without changing an oscillator admittance according to the direction of rotation.

Title: Formation of pattern and lithographic apparatus
Inventor: SUGA OSAMU
IPC: H01L21/027
Filed: 1988-04-15
Abstract: PURPOSE:To reduce or eliminate a proximity effect effectively by a method wherein a whole part of a resist layer is exposed only in a contour part of a figure to be drawn and only a resist surface layer is exposed inside the contour part. CONSTITUTION:Figures 2, 2' to be drawn are broken down with contours 8; only resist surface layers are exposed 10 at contour parts inside parts 9 having a large drawing area; substratum backward scattering is not caused; an exposure 11 reaching a substratum substrate 4 is executed at contour parts 8 having a small drawing area in order to suppress an undercut or the like. By this setup, a proximity effect can be reduced remarkably; also a good pattern cross section can be obtained. When the contour parts and its inside parts are exposed separately, a problem is anticipated at an overlapping operation of both. That is to say, an overlapping error of about 0.2-0.3mum is caused normally at different exposures using a lithographic apparatus. When the error is caused, an unexposed part is produced at a boundary part of the contour parts. When a figure is divided into the contour parts and its inside parts, it is practically desirable that the overlapping error is taken into account and that its inside figure is expanded as necessity requires.

IPC: B60S1/08
Filed: 1986-04-21
Abstract: PURPOSE:To enable detection of fine water drops, by forming opposed electrodes with different pitches therebetween. CONSTITUTION:A window shielding glass 2 is placed into a vacuum film former and an ITO transparent conductive film 21 is deposited on the glass from above a pattern 18 of a masking agent to be attached almost evenly onto the film and then the work is withdrawn from the vacuum film former to remove the masking agent 18 together with the ITO film 21 thereon. By so doing, a comb- teeth type electrode with a coarse pitch and a power feeding electrode are completed. Thereafter, a resist film 22 is applied evenly on an area 20, a mask 23 which is formed by patterning chromium on a glass dry plate 24 at a fine pitch is placed thereon and the resist film is exposed to ultraviolet rays. Then, the work is immersed into a developer, washed with water to remove the resist film exposed and immersed into an etching liquid to remove the ITO film. Moreover, it is immersed into a sulfuric acid-hydrogen peroxide solution to remove the resist film 22. Thus, a rain drop sensor 1 combines two comb-teeth electrodes, the one coarse and the other fine in the pitch.

SOLUTION: In an anchor-shaped clip comprising a flange 1B, a shaft 3 suspending from a lower face of the flange and a pair of locking legs 4 expanded in the upper outward direction from a lower edge of the shaft, a pair of thin cover members 5 are suspended from the lower face of the flange for covering the outer faces of the locking legs, and the cover members and the locking legs are relatively slidable, so that the cover members are caught by an edge of a mount hole of a panel when the anchor-shaped clip is drawn out from the mount hole of the panel, and stopped at the position with the deformation.  On the other hand, the locking legs are relatively slided to the cover members, so that they can be easily drawn upwardly, and further the cover members can be drawn out from the mount hole of the panel when the points of the locking legs are passed through the mount hole of the panel. Whereby a component can be demounted from the panel without fracturing the anchor- shaped clip.

Abstract: PURPOSE: To improve the energy utilization efficiency by a method wherein either operation  among heat pump operation, heating operation by combustion and solar heat collector operation  is adopted in accordance with the open air condition in the cooling and heating apparatus with  hot water supply.  
     CONSTITUTION: The hot water supply during the cooling operation is performed by using the hot  water in the solar heat collector. During the heating operation, when the outside temperature is  above 5°C, a four-way change-over valve 3 changes over the circuit of the apparatus to the circuit  for heat pump operation actuated by a compressor 2 to heat the circulating water through an  availing heat exchanger 7. When the outside temperature lowers below 5°C, the compressor 2 is  stopped, a three-way change-over valve 10 is changed over to the water heater side and a combustion device 11 is started to heat the circulating water by passing it through the water heater  12. The hot water is supplied from the water heater 12, in which the water in the solar heat  collector 14 is stored being sent by a circulating pump 16, when it has enough high temperature at  the outlet of the collector 14. When the temperature in the collector 14 is low, the circulating  pump 16 is stopped and the circulating water is heated by the combustion device 11 to be supplied  as the hot water. In such a manner as mentioned above, the full amount of hot water can be  supplied even during the heat pump operation.
