IPC: C03B11/08
Filed: 1991-07-24
Abstract: PURPOSE:To efficiently produce a glass lens having high-precision optical face in short forming cycle while suppressing upper and lower fitting tolerance of a mold in such degree as not to impair lens performance in forming apparatus for forming the glass lens under pressure while carrying the mold. CONSTITUTION:Plural pairs of molds having an optical face for transferring a forming lens 150 under pressure are provided and upper and lower molds 10 and 11 are each used as movable mold and fixed mold and a glass material 13 is packed into the above-mentioned molds and these molds are fitted and each upper and lower molds 10 and 11 are fed into one closed chamber composed of an insulating material and controlled at prescribed uniform temperature to subject the glass material to press forming.

Title: Air conditioner for vehicle
Inventor: KATAHIRA HIROKIMI
IPC: B60H1/32
Filed: 1982-10-21
Abstract: PURPOSE:To make a compressor perform good air conditioning without any drop in engine power performance, by disconnecting a magnet clutch and stopping the compressor for a specified period of time after detection of suction pressure in time of full acceleration, while forcibly operating the compressor in time of detection of the suction pressure other than said full acceleration. CONSTITUTION:When suction pressure in a suction pipe becomes below 40mm.Hg, the output of a timer 7 comes to a low level whereby a time constant rises. Under this condition, one side input terminal potential of a comparator 12 goes up, exceeding a partial pressure value VT2, and the output comes to a low level as well. If so, a transistor 13 is turned off, causing the movable contact of a relay 14 to open, and a continuous rating current to a magnet clutch 15 is shut off whereby a compressor stops. When the output of a timer 7 exceeds a partial pressure value VT1, the output of a comparator 8 becomes a low level, and the terminal potential of a comparator 12 drops so that the partial pressure value VT2 also goes down. If so, the output of the comparator 12 comes to a high, level, turning on the transistor 13, and the continuous rating current to the magnetic clutch 15 takes place, thus a compressor operates and good air conditioning is kept up.

The partial shutters 12a and 12b are formed of stops, and the beam shutter 12 is controlled by a control device ST, whereby laser pulses are introduced to either a resonator beam path or a laser crystal 13 so as to be nearly suppressed or eliminated.

The thin film transistor 41 and a transparent pixel electrode 42 are formed in layers different from each other. It is not necessary to form a space between the transparent pixel electrode 42 and data wiring 38 in this array substrate compared to a structure having a thin film transistor 41 and a transparent pixel electrode 42 in a same layer, and thereby, the opening ratio can be increased.

Title: Stock for current transformer excellent in impedance ratio permeability in magnetized state
Inventor: SHIMIZU YASUHIRO
IPC: C22C19/03
Filed: 1995-07-21
Abstract: PROBLEM TO BE SOLVED: To produce a stock for a current transformer excellent in impedance ratio permeability in a magnetized state, in an Ni-Fe alloy contg. specified amounts of Ni and Fe, by regulating the grain size and the intensity of the texture to specified ones. SOLUTION: This Ni-Fe alloy has a compsn. contg., by weight, 75 to 85% Ni, and the balance substantial Fe. The grain size of the alloy crystals is regulated to 125 to 175μm. The intensity of the  100} texture is regulated to 1 to 2.5. In the case the grain size after magnetic annealing is less than 125μm, they are fine grains, so that, at the time of a magnetizing process, the movement of magnetic domain walls shall be executed by penning to deteriorate the impedance ratio permeability. In the case of >175μm, they are coarse crystalline grains, so that the moving distance of the magnetic domain walls is lengthened in the magnetizing process, and they can not follow the inversion of the magnetization to generate loss and to deteriorate the impedance ratio permeability.  In the case the intensity of the  100} texture is less than 1, the cold rolled texture  100} remains to deteriorate the permeability. In the case of >2.5, uniaxial magnetic anisotropy develops to deteriorate the impedance ratio permeability.
