Title: Circuit formation
Inventor: KANAE MASAAKI
IPC: H05K3/10
Filed: 1989-04-03
Abstract: PURPOSE:To speed up the rate of circuit formation and improve mass production efficiency by transferring a conductor thin film which is provided on the surface of a glass plate after evaporating its thin film with a laser and then, forming an electric network. CONSTITUTION:In addition to irradiating a laser 4 from the side of a glass plate 1, the laser 4 is made to scan the desired circuit pattern. When the laser 4 irradiates, only a part of a conductor thin film 2, to which the laser 4 irradiates, evaporates and its film peels off from the glass plate 1. Coming into collision with the upper part of a substrate 3, the pattern is transferred on the board 3. Then the thin film 2 that is provided at the glass plate 1 is transferred on the upper face of the substrate 3 after being formed into a line shape in the scanning direction at the irradiating width of the laser 4. The electric network 5 of the desired pattern is formed by scanning the laser 4. Circuit formation which is superior in mass production efficiency is thus obtained without being limited by the material quality of the board.

Abstract: PURPOSE:To simplify the structure of a tape loading mechanism part by providing a means for biasing main- and sub-levers to be rotated in their directions outside a prescribed angle range, so as to be against themselves in rotation in the most area of the prescribed angle range. CONSTITUTION:When a driving gear 28 is rotated counterclockwise, the main- and sub-levers 26 and 27 comes to a standstill under the state of drawing each other by a tension spring 34. And, when the driving gear 28 is rotated clockwise, the main-lever 26 engaged with a gear 28T and a gear 26T and the sub-lever 27 engaged with a gear 26t and a gear 27t are rotated in the opposite direction to each other, and the driving gear 28 is rotated against a bias force of the tension spring 34 to progress the tape loading operation. When the tension spring 34 is beyond a dead position of its max. extension, the driving gear 28 and the main-lever 26 are released from their engagement, and the bias force of the tension spring 34 works in the direction of helping the rotation of the main- and sub-levers 26 and 27, and hence the main- and sub-levers 26 and 27 continue their rotations to complete the tape loading operation.

Abstract: PURPOSE:To improve the efficiency of light convergence by arranging plural lenses including one Fresnel lens in parallel to an optical axis and cutting the incidence-side lens surface of the Fresnel lens arranged behind the 2nd or succeeding lens from the incidence side of light in parallel to the incident light. CONSTITUTION:A light converging device is constituted by arranging two Fresnel lenses 1 and 3 which each have a saw-tooth surface on one side in parallel and projections of the Fresnel lens 3 are formed in parallel to the incidence direction of an incident light beam L. The angle theta of one surface 31 of a projection to a horizontal surface is varied according to the distance from the center of the Fresnel lens 3 and increased toward the peripheral part of the lens. Consequently, part of the incident light beam L which is incident between light beams (b) and (a') within a hatched range reaches a slanting surface 31, so it is not converged on a focus F1, but its quantity of light is very small, thereby improving the efficiency of light convergence greatly.

Filed: 1984-04-27
Abstract: PURPOSE:To control the opening and closing periods of a suction and exhaust valve automatically and device to prevent blow-bye at low speed of an engine by constructing the coupling position of a rocker arm with a push rod movably adjustable to make the rocker ratio variable. CONSTITUTION:When a solenoid valve 24 is opened the oil pressurized by a pump 25 is led to a duct 21 through a hole 23 and a small hole 22 in a rocker arm shaft 6 and is further led into a cylinder 19 in a rocker arm 5 through a smaller hole 20. By this arrangement a piston 18 inside the cylinder 19 moves leftwards by opposing to a return spring 26. A slider cap 16 firmly holding the piston 18 moves leftwards within a concave portion 11 and a slider 13 coupled to the cap 16 moves leftwards along an inclined plane 12. The result is that the distance between the slider 13 and the center of the shaft 6 becomes larger and thus the rocker ratio becomes small. Therefore, in this case, the opening period of a suction valve 1 can be made long.

Title: Liquid crystal display device
Inventor: HATASHITA TOYOHITO
IPC: G02F1/133
Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To make the liquid crystal display device operate only when specified data are transmitted, and to prevent the device from unauthorized use by decoding and recording a defective position from read-out data and comparing the recorded data with the input data. SOLUTION: At the time of turning on a power supply source, a scanning control means 101 instructs a recording means 103 to clear recorded contents and also instructs a LCD controller 504 to write all the data of '1' in a liquid crystal panel 501, and following that, it instructs read-out to sequentially read all the data from the liquid crystal panel 501. When the scanning control means 101 is notified that a defective position information has been recorded, it stops reading and instructs the LCD controller 504 to start comparison. The scanning control means judges a result to be sent from the comparison means 104, and when the result agrees, it performs an ordinary operation, and when the result does not agree, it controls the display device not to display.  Thus, since this device not operate without knowing intrinsic information on the liquid crystal, unauthorized use of the device is impossible.

Title: Method to manufacture carboxylic acid halogenide and carboxylic acid salt simultaneously
Inventor: MATSUKUSU BURAUN
IPC: C07C51/60
Filed: 1994-04-25
Abstract: Described is a process for the preparation of halides and salts of carboxylic acids by the reaction of metal halides or "onium" halides with carboxylic anhydrides. The process is highly suitable for processing anhydrous spent catalyst preparations. The halide or salt of a carboxylic acid which has been prepared can be used as acylating reagent or alkylating reagent. Metal halide or "onium" halide liberated in this process can be regenerated by re-reacting with carboxylic anhydride. This allows hydrolysis-free alkylation of acylation to be effected without obtaining salt-type waste products. If the mixture of halide and salt of carboxylic acid is reacted with an alcohol, preferably in situ, the resulting esters may be isolated without hydrolysis.
