Title: Square corrugated plate exterior structure
Inventor: ISHIHARA TAKAHIRO
IPC: E04B1/86
Filed: 1998-07-21
Abstract: PROBLEM TO BE SOLVED: To improve bending deformation strength of square corrugated enclosing plates, and to enhance vibration control performance by compounding/joining two square corrugated exterior plates molded as trapezoidal continuous waves so that the directions of the continuous waves become mutually parallel to each other by mutually dislocating the respective continuos waves by a prescribed pitch by mutually reversing the top and bottom. SOLUTION: First/second square corrugated exterior plates 4, 5 formed as trapezoidal continuous waves are compounded/joined through a cushioning material 9 so that respective trapezoidal continuous waves are mutually dislocated by 1/2 pitch in the opposite direction with a contact plane as a boundary by mutually setting the top and bottom in the inverse direction to thereby form a structure for largely increasing a section modulus, so that rigidity of the exterior plates 4, 5 is enhanced and a substantial thickness increases. Thus, quantity of a support material can be reduced, and vibration can be restrained by restraining a weight increases to the minimum.

Filed: 1989-08-08
Abstract: PURPOSE:To easily evaluate the frequency property of a driving signal in a wafer step or after assembly and to facilitate frequency property evaluation at a low temperature and a high temperature by controlling the output of a refresh address counter by the driving signal. CONSTITUTION:In a CBR cycle, an 'L' is impressed to a TE terminal and phiT is made 'L'. Then, FET-QN1 and QP1 are turned ON and phiA becomes phiA'. Afterwards, the data of refresh address counters RAC 8A-8N are increased only by 1. In a test cycle, the inverse of an RAS and the inverse of a CAS are made 'H' and a memory 15 is set in a standby state. At such a time, 'H' is applied to the TE terminal and the phiT is made 'H'. Then, the QN1 and QP1 are turned OFF and QN2 and QP2 are turned ON. A phi0 becomes the phiA' and the phiA' is clocked by the period of a self-exciting oscillator 1. Accordingly, when the time of the test cycle is defined as tc and the period of the oscillator 1 is defined as to, the data of the RAC 8A-8N are increased only by tc/to.

Title: Gravure printing method
Inventor: HAMADA MINORU
IPC: B41F31/06
Filed: 1987-08-19
Abstract: PURPOSE:To eliminate the need for an expensive equipment, and to reduce the cost of printing by comparatively increasing difference in dimensions of the width of a plate cylinder and an impression cylinder and passing printing sheets near both edges of the plate cylinder at intervals in the upper section of the plate cylinder. CONSTITUTION:Printing sheets 5 are elongated and wrinkles are generated when spaces among the printing sheets 5 near both ends of a plate cylinder 1 and the plate cylinder 1 are too large, and there is possibility in which the ink of the plate cylinder 1 adheres on the surfaces of the printing sheets 5 when the spaces are too small, thus bringing the spaces to approximately 10mm. Difference in dimensions of the width of the plate cylinder 1 and an impression cylinder 4 depends upon spaces with the printing sheets 5 near both edges of the plate cylinder, the material of the printing sheets, the coverage of ink and other factors, but approximately 10cm is formed normally on one side as the difference. Consequently, difference in dimensions of the width of the plate cylinder and the impression cylinder is increased comparatively, and the printing sheets near both edges of the plate cylinder can pass at intervals in the upper section of the plate cylinder, thus preventing adhesion on the surfaces of the printing sheets of ink protruding at both edges of the plate cylinder. Accordingly, printing can be conducted at low cost with a small printer.
