Abstract: PURPOSE:To mold a large shaped product in which a massive shape is variously altered by the same female mold with concrete. CONSTITUTION:A rocklike large male mold is fixed to a support base, covered with an elastic material such as natural rubber, synthetic rubber, etc., except a part in contact with the base, and many chain rows or metal gauze bands 30 are mounted along a gradient from its top pole toward a periphery of the base on the covering layer to form a female mold. A lower half of the layer is cut to a plurality of divided pieces 12 along the gradient by avoiding the rows and the bands, and fasteners 21 for switching cracks are provided at the cracks. The cracks are opened by the fasteners, the female mold is released from the male mold and the base. Then, the fasteners are closed.

IPC: G06F7/02
Filed: 1983-05-16
Abstract: PURPOSE:To realize an operation to supply two operands as they are in a logic comparison processing mode and another operation to supply the two operands after inverting only the code bits of these operands in an arithmetic comparison processing mode, by constituting a comparator only of a logic comparison function. CONSTITUTION:A logic comparator 4 has only output functions for coincidence (=), larger (>) and smaller (<) states, respectively. Both the 1st and 2nd operand data 1 and 2 are supplied to the comparator 4 via exclusive OR circuit 3 and 3, respectively. An arithmetic comparison signal C is used as an input of the other side of the circuit 3. The data 1 and 2 are supplied to the comparator 4 as they are if they are logic data. While the signal C is applied to the comparator 4 in the form of a signal obtained by inverting only the code bit in the case of the arithmetic data. Thus it is possible to perform a comparison operation between the arithmetic data and the logic data through a single comparator.

Title: Bonding of nozzle plate
Inventor: AOKI NOBUO
IPC: B41J2/16
Filed: 1996-03-13
Abstract: PROBLEM TO BE SOLVED: To provide a nozzle plate bonding method not generating the positional shift of nozzles and channels even if the nozzle plate and an actuator are thermally expanded when the adhesive interposed between them is heated and cured. SOLUTION: The distance A between both end nozzles among a plurality of the nozzles 4a formed on a nozzle plate composed of a polyimide resin is set so as to be made shorter than the distance B between both end channels among a plurality of the channels 3 formed on an actuator 2 composed of piezoelectric ceramics by the distance corresponding to the difference between the coefficients of thermal expansion of a polyimide resin and piezoelectric ceramics. Since the coefficient of thermal expansion of the polyimide resin is larger than that of piezoelectric ceramics, the positions of the nozzles 4a and the positions of the channels after thermal expansion correspond properly.

Title: Optical writing head
Inventor: KASAO ATSUSHI
IPC: H01J63/06
Filed: 1987-04-09
Abstract: PURPOSE:To use a vacuum fluorescent tube and to obtain an optical writing head capable of having high luminous intensity, by setting density of thermion beams passing through a second grid larger than that of thermion beams passing through a first grid. CONSTITUTION:Density of thermion beams passing through a second grid 14 is set larger than that of thermion beams passing through a first grid 13. Name ly, two grids 13 and 14 are prepared, and thermion beams collected at aperture parts of the first grid 13 are focused at aperture parts of the second grid 14, so that density of thermions reaching an anode 12 is enlarged. It is effective to set widths of apertures of both grids, for example, so that a width of each slit-shaped aperture of the first grid 13 becomes larger than 1.2 times width of each slit-shaped aperture of the second grid 14. When thermions pass through the grids 13 and 14, density of thermions is thus enlarged so that sufficient luminous intensity can be obtained, and also high-speed recording and high quality picture recording are enabled. Since the grids 13 and 14 are disposed on two stages, sizes and luminous intensity of luminous dots can be easily controlled.

Title: One-way clutch
Inventor: SATO NAOTO
IPC: F16D41/07
Filed: 1997-03-18
Abstract: PROBLEM TO BE SOLVED: To prevent the rising part of a friction plate, which occurs at the time of spot welding, from coming into contact with a mounting flange by fitting a mounting piece deviated in the flange direction at the friction plate, and fixing the mounting piece at a flange. SOLUTION: A friction plate 40 deviates the retainer 41 of its mounting piece inwards and is spot-welded to the flange 34 of a retainer 32. Even if a rising part occurs at the exterior side surface of the friction plate 40 at the time of spot-welding, the rising part comes into no contact with the right surface of a mounting flange 20, and the outer peripheral end of a friction piece frictionally-engages with the right surface of the mounting flange 20. It is thus possible to stabilize the operating characteristics of a sprag 28, mainly one-way clutch.

A key board is then decided according to a program for deciding the key code and the address of the character generator corresponding to the character pattern is stored into a character pattern memory; at the same time, the inputted character is displayed on the CRT display part. A desired number is thereafter inputted from a ten key. A RETURN key is used to update the data of the number and an ESC key is used to end the user operation. The CRT display of the user data is made possible by depression of a user call key. The application for the copying machine and the development of the program to be used exclusively by the user are thus made possible.
