Abstract: PROBLEM TO BE SOLVED: To produce a gap between substrates with accuracy smaller than 0.1 μm by performing sticking with magnetic force in a substrate sticking process for sticking two substrates for liquid crystal panel while keeping the fixed gap. SOLUTION: After two substrates 10 and 11 are aligned in advance while arranging a seal resin 12 and beads 13 between them, ferromagnet 16 such as stainless steel are laminated and installed outside one substrate 11 and further, magnet plates 15 such as electromagnetic magnets are laminated and installed outside the other substrate 10. In such a state, the magnet plate 15 is electrified, uniform magnetic force is operated between the ferromagnet 16 and the magnet plate 15, and two substrates 10 and 11 are stuck. After two substrates 10 and 11 are stuck like this manner, liquid crystal is injected and charged into a gap 14.  In this case, the ferromagnet 16 or magnet plate 15 is used to be temporarily laminated in the substrate sticking process and after the end of the substrate sticking process, they can be respectively separated from the substrates 10 and 11 for liquid crystal display.

CONSTITUTION:Water evaporating fins 12 are arranged in a detachable evaporating pan 11 and are fixed by a fixing frame 12b at the lower part thereof while the fins 12a are made by a hydrophilic porous material. Water, produced by defrosting, enters into an evaporating pan through a drain pipe 13 and the fins 12a are impregnated with water to the tip ends thereof since the water evaporating fins 12 in the evaporating pan 11 are excellent in hydrophilic property while the fins are exposed to air at all times whereby the surface areas of the fins are permitted to be used effectively. Water in the evaporating pan 11 is warmed by the heat of a drain condenser 8 and the dissipated heat of warm air of a compressor 11 whereby the temperature of the water becomes a high temperature. The flow of air of a machine room 4 enters from the suction hole 5a of a base 5 and cools the compressor 11 and the drain condenser 8 sequentially while the warm air is discharged through the upper slits 4a of the cover 4 of the machine room so as to effect on the water evaporating fins 12 effectively. According to this method, the improvement of the evaporating capacity of the water, produced by defrosting, and the miniaturization of the drain evaporating device may be realized.

Title: Setting circuit of test loop
Inventor: IMAI KAZUO
IPC: H04M3/22
Filed: 1983-01-17
Abstract: PURPOSE:To obtain a test loop setting device which needs no change of allotment of channels by setting in time division a folded loop for test only to the corresponding subscriber channel. CONSTITUTION:A folded loop is actuated when an envelope start signal F 100100S (S=''0'') is received continuously in three envelopes. This loop is maintained thereafter if the signal F100100S (S=''0'') is detected every 15 envelopes during transmission of test data. For instance, the folded loop is started with a channel of 9.6kb/s. In such a case, it is enough just to transmit an envelope signal of F100100S (S=''0'') to each of three time slots A1-A3. This loop can be maintained just by transmitting the signal F100100S (S=''0'') every A3+15n (n=1, 2...) time slots. In the same way, the signal F100100S is transmitted to three time slots B1-B3 in the case of a channel of 4.8kb/s.

Abstract: PURPOSE:To etch an silicon nitride film in an anisotropic manner, sufficiently keeping an etching selection ratio to an silicon layer while preventing the deposition of a polymer to an etching chamber by dry etching the silicon nitride film on an silicon surface, using difluoroethane as a reaction gas. CONSTITUTION:An upper electrode 2 in a chamber 1 is grounded, and a high-frequency power supply 5 is connected to a lower electrode 3 on which a material to be etched 4 is placed. C2H4F2 is introduced into the chamber 1 from a gas introducing port 6, and exhaust is adjusted from an exhaust port 7 so as to hold pressure in the chamber 1 at 50m Torr. High-frequency power is applied to the lower electrode by the high-frequency power supply 5, C2H4F2 made to flow through the gas introducing port 6 is excited, and said material to be etched 4 is etched. Since the reaction gas of C2H4F2 is employed, the etching of an silicon layer hardly progresses to the etching rate of an Si3N4 film.

Abstract: PURPOSE:To facilitate the miniaturization of the equipment as a whole while smaller load of a rotating object to be inspected, by providing a reflecting means in which a reflecting surface is arranged to reflect specified order of diffraction light alone near a focal plane. CONSTITUTION:A convex lens 141, a reflecting mirror 151 and a mask 161 forms an optical system as a part of reflecting means and a luminous flux projected in parallel to the concave lens 141 is focused on the reflecting mirror 151 through the mask 161.

The optical system of the reflecting means thus arranged allows the removal of this diffraction lights other than specified order of diffraction light L1 such as zero order of one incident into the convex lens 141. Thus, this can reduce the distance between the radiation grating 6 and the reflecting means 141, 151 and 161.

Title: Engine control method for vehicle with continuously variable transmission
Inventor: TAMURA TADASHI
IPC: B60W10/10
Filed: 1988-01-14
Abstract: PURPOSE:To quickly maximize the transmission ratio of a continuously variable transmission at the sudden braking time of a vehicle by compensating the angle of advance that the ignition timing of an engine is changed to increase the output of the engine when a sudden braking of the vehicle is detected. CONSTITUTION:When a brake switch 55 is in the ON position and the running speed of a vehicle is below the specified value and the deceleration speed of the vehicle is higher than the preset value, the state of the vehicle is detected as the braking state. At the time of the braking such that driving wheels are interrupted before the transmission ratio of a continuously variable transmission 16 reaches to the maximum, an ignition timing adjusting device 59 is operated to make an ignition of an engine at such an ignition timing that the angle of advance is increased by the angle corresponding to the deceleration speed of the vehicle. The rotation of an engine 10 is therefore increased by the specified value to increase the quantity of oil discharged from an oil pump 41, whereby maintaining the discharge pressure high. As a result, a line oil pressure is increased so that the transmission ratio readily reaches to the maximum if sudden braking is applied.
