Title: Brake device for focal plane shutter
Inventor: SEKIZAWA KOJI
IPC: G03B9/36
Filed: 1998-06-16
Abstract: PROBLEM TO BE SOLVED: To provide a brake device having stable braking force. SOLUTION: The brake member 30 is rotatably supported on a position for cushioning in terms of the traveling path of a blade driving member 13 driving a blade 11, the member 13 gives the member 30 torque in a left-turning direction after the engaging pin 18 of the member 13 is engaged with an arm 32, and the kinetic energy of the member 13 is converted to heat energy generated by the member 30 and attenuated.  A cushioning member 34 exerts its influence of elastic force on a circular projecting piece formed on the member 30 when the projecting piece abuts on the member 34 having the elastic force; however, since the direction of the elastic force faces to the direction of the rotating shaft 31 of the member 30, the elastic force exerted by the member 34 to the member 30 does not generate torque with respect to the member 30, and the risk for reverse rotation by rebounding can be prevented.

Title: Semiconductor integrated circuit device
Inventor: URUMA KOJI
IPC: H01L21/66
Filed: 1991-07-09
Abstract: PURPOSE:To make a semiconductor integrated circuit escape from the state of latch up danger in case it falls into that state by shutting off the output of an internal power source voltage generating circuit based upon a voltage of a semiconductor substrate detected by a detecting circuit. CONSTITUTION:In a normal condition, a semiconductor substrate 1 is in the state of reverse bias for a higher resistance against a latch up, and in that case, a substrate voltage Vsub is negative. At the state of latch up danger, that is, when a voltage of the semiconductor substrate 1 changes from negative to positive to reach a certain voltage, the output of a detecting circuit consisting of high resistances 8 and 9 and an inverter 10 changes from a high level to a low level. A voltage bringing down circuit 11 shuts off an output according to the signal from the detecting circuit. By shutting off of the output from the voltage bringing down circuit 11, an internal power source voltage int.Vcc is not applied to an internal circuit 12, as a result, a semiconductor integrated circuit can escape from the state of latch up danger.

Title: Liquid crystal element
Inventor: TAKAHASHI NOBUO
IPC: G02F1/1368
Filed: 1991-07-10
Abstract: PURPOSE:To conceal orientation abnormality and an orientation defect of a liquid crystal in the vicinity of a picture element electrode end part, which become the cause of a light leakage by providing a light shielding layer without making a picture element opening part narrower than necessary and with high alignment accuracy. CONSTITUTION:The liquid crystal element is constituted so that on the lower part of a picture element electrode 102 and a boundary 106, a conductive light shielding layer 108 insulated therefrom is provided.

Title: Manufacture of reflection preventing film for solar battery
Inventor: NAKANO HIROTAKA
IPC: H01L31/0216
Filed: 1980-11-29
Abstract: PURPOSE:To obtain a TiO2 reflection preventing film by a method wherein a substrate on which a photo-electromotive force junction plain is formed is immersed in a solution which contains Ti(OR)4 or TiCl4 and is lifted up at a required speed and is treated by heat. CONSTITUTION:An Si substrate on which a photo-electromotive force junction plain is formed is immersed in a solution of ethanol and ethyl acetate which contains 3.4% Ti(OC3H7)4 and is lifted up at a speed of 2.5mm./sec., so that the substrate is covered by a thin film of TiO2. The substrate is then burnt at a temperature not less than 300 deg.C. If the burning temperature is less than 300 deg.C the reflection preventing film will be darkened and if it is more than 1,100 deg.C a silver electrode will melt. The strength and adhesion of the film are significantly increased by the heat treatment. The thickness of the TiO2 film is determined by the lifting speed and the density of Ti(OR)4. The film thickness d which makes the reflection index minimum when a wavelength lambda0 is nearly 500nm is calculated by a formula nd=lambda0/4, where n is a refractive index, thus d=550-800Angstrom  is most preferable. With the above method, a uniform reflection preventing layer can be obtained very easily at low cost by controlling the film thickness.

Title: Production of steel sheet having excellent weatherability and sea water resistance
Inventor: FURUKIMI OSAMU
IPC: C22C38/32
Filed: 1986-07-17
Abstract: PURPOSE: To obtain a laminated steel sheet having excellent toughness, weldability, etc., by laminating steel sheets each formed by imposing a cladding metal of a limited thickness and compsn. on a base metal, via release materials and heating the laminated steel sheets in a limited temp. range, then rolling the heated sheets and separating the same to one unit. CONSTITUTION:One unit of the steel sheet 2 is formed by imposing the cladding metal 4 having 10mum-2mm thickness and consisting of a steel made of a compsn. contg., by weight, 1-40% Cr, 1-35% P aud 0.5-10% total of C and B, or the steel contg., by weight, of 1 or 2 kinds of 0.05-5% Cu and 0.05-5% Ni in addition to said components on the steel base material 3. A steel material 6 is then imposed via the release material 5 on the cladding metal 4 side of one unit of the laminated steel sheet 2 and after the steel sheets are heated for >=30 minutes in the temp. range T1-T2 determined by the equations 1, 2 (where C, B, P, Cr are W% of the respective elements in the cladding metal), the steel sheets are rolled and are separated to one unit of the laminated steel sheet. The reason for limiting the thickness and compsn. of the cladding metal 4 lies in that there is no improvement in the effect of the weatherability and sea water resistance if the contents are out of the limited ranges.

Title: Production of cold rolled steel sheet and galvanized steel sheet for deep drawing excellent in ridging resistance
Inventor: MATSUOKA SAIJI
IPC: C21D9/48
Filed: 1996-06-28
Abstract: PROBLEM TO BE SOLVED: To improve the ridging resistance of a steel sheet by regulating the steel components and hot rough rolling and finish rolling conditions therein. SOLUTION: As the steel components, 0.01 to 0.2wt.% Ti and 0.001 to 0.2wt.% Nb are most important. Fix solid solution C in the steel is precipitated and fixed as carbide and reduced so as to prevent deterioration in its deep drawability. In this rolling stock as the above, rough rolling is finished at (the Ar3 transformation point -50 deg.C) to 950 deg.C, and after that, finish rolling is executed under the following conditions: the product T×ε of the rolling temp. T and the draft ε is regulated to >=37000, and also, the rolling temp. in the ferritic region at least in one pass is regulated to >=820 deg.C. In this way, its ridging resistance can be improved.  The reason is that, in the steel subjected to the hot rolling in the ferritic region under the above conditions, even if colonies exerting bad influences on its ridging resistance are formed, the crystal grains in the colonies are randomized by the rolling-recrystallization.
