Title: Preparation of plate material made of polymer material by rolling
Inventor: KIKUMA TOSHIO
IPC: B29C55/14
Filed: 1986-09-30
Abstract: PURPOSE:To enhance tensile strength and Young's modulus and to reduce the anisotropy of said characteristics in a plate surface, by unidirectionally rolling a polymer material extruded while kneaded under heating in a plastic state and further rolling the same in the direction crossing the unidirectional rolling at a right angle without lowering the temp. of the polymer material to the vicinity of room temp. CONSTITUTION:The polymer material extruded while continuously kneaded under heating by an extruder 2 is rolled in one direction, for example, in the longitudinal direction under a temp. region of m.p. or less by a longitudinal direction rolling machine 3 and subsequently rolled by reciprocating the rolling roll of a tentering rolling machine 4 in the direction crossing the longitudinal direction almost at a right angle, for example, in the lateral direction without lowering the temp. of the polymer material to the vicinity of room temp. to continuously perform extrusion, longitudinal direction rolling and lateral direction rolling. The plate material of the polymer material thus formed has high tensile strength and high Young's modulus and the anisotropy of said characteristics in the plate surface is low. Since this method is made consistently continuous from extrusion to the plate material product, productivity is high.

Title: High pressure load circuit
Inventor: IKEUCHI HIROSHI
IPC: G01R31/00
Filed: 1989-09-05
Abstract: PURPOSE:To protect a triode regardless of variations in characteristic at stages by arranging a constant voltage diode in which an anode and a cathode are connected to a plate and a grid of the triode respectively. CONSTITUTION:A zener voltage of a constant voltage diode Z is set at a voltage lower slightly than the maximum rated voltage of a triode TB. This is to pre vent malfunctioning otherwise caused by a voltage drop portion of a resistance R with the electric energization of the constant voltage diode Z and a voltage drop portion of a grid leak resistance Rr attributed to a grid leak current. Now, there is a difference in characteristic between basic circuits 10 and 10 at respective stages and when a voltage is at a point to approach the maximum rated voltage being biased, the constant voltage diode Z is conducted immediate ly before it happens. As a result, a grid voltage Vg rises to lower impedance of the triode TB. This causes a change in the sharing ratio to lower a voltage applied to the triode TB. This can avoid the application of a voltage beyond the maximum rated voltage.

Title: Method and equipment for writing pattern and sample fixing jig therefor
Inventor: GOTO TAISAN
IPC: G03F7/20
Filed: 1993-09-16
Abstract: PURPOSE:To enhance the accuracy of writing position by putting a plurality of marks on a sample fixing jig, measuring the positions thereof at a predetermined period during and before the writing operation, determining the correction coefficient sequentially and feeding back to the writing operation. CONSTITUTION:When a pattern is written at a desired position of a sample P set in a sample fixing jig 21 by means of an energy beam, position measuring marks 24, 25, 28, 29 are put on the jig 21. The marks 24, 25, 28, 29 are detected by means of the energy beam at a predetermined period during the writing operation of the sample P. The variation of mark position and the variation of distance between marks are then calculated based on the detection results and the pattern is written on the sample P while correcting the writing position sequentially based on the variation data. This method enhances the accuracy of writing position regardless of the temperature drift of sample, thermal/ mechanical strain drift thereof, etc.

Title: Method and apparatus for manufacture of cushioning material for packing
Inventor: KOUSHIN MASAHIRO
IPC: B65D81/09
Filed: 1992-08-28
Abstract: PURPOSE:To prevent damages from occurring to outer bags for filling cushioning materials therein for encasement of electric appliances by a method wherein the outer bag material, unwound from a roll, is temporarily pooled and is drawn out while its opening is opened and after the material is filled with cushioning material, the opening is sealed up with vents left unsealed and after air inside the material is let out, the rear end of the material is cut by weld-cutting. CONSTITUTION:Outer bag material, unwound from a roll 9, is temporarily pooled in a pooling mechanism 10, and is successively fed with a feeding mechanism 11. As the front end of the material is projected beyond a cutting mechanism 12 for weld-sealing, pinch rollers 18b are separated on signals outputted from a sensor and at the same time, the upper and the lower faces of the front end are attracted with a sucking means and an opening is formed thereby. The material is then moved toward an opening forming part 4 and the front end is completely opened. After the material is filled with cushioning materials, the opening is sealed up by welding with vents left unsealed. Then, the material is moved in the direction of pulling back by reverse rotation of the pinch rollers 18b and thereby air inside the bag is let out. Then, the material is cut by means of weld-cutting with the cutting mechanism 12 for weld- sealing.

Title: Sample surface inclination detector for ultrasonic microscope
Inventor: UCHINO FUMIO
IPC: G01N29/26
Filed: 1982-12-27
Abstract: PURPOSE:To facilitate the adjustment of inclination of a sample surface by automatically detecting the inclination of the sample surface based on the output of a receiving voltage transducer arranged in an acoustic lens. CONSTITUTION:Receiving piezo-electric transducers T2a-T2d vibrate receiving the primary sublobe part of reflected sound waves to generate an electrical signal according to the intensity thereof. Electrical signals are introduced into a signal processing circuit 41 and compared with one another in the level by comparators 41a and 41b. Now when the sample surface is inclined from the level position, the intensity distribution of the reflected sound waves is such that the intensity is large and dense at the part reflected from the sound source while small and coarse at the part reflected on the surface for away therefrom. For example, when the sample surface is inclined from the level position in the X axial direction, a comparator 41a discriminates this and sends a signal to an X-axis angle adjustment display 42 to turn on a specified lamp. This facilitates the adjustment in the inclination of the sample surface.

Abstract: PROBLEM TO BE SOLVED: To prevent effectively and easily various vibrations of diagonal cables in a cable stayed bridge. SOLUTION: A cylindrical magnetic material 2 surrounding a part of a diagonal cable 6 portion is surrounded with a distance from the outer periphery of the magnetic material 2. The vibration of a diagonal cable 6 is restricted at a part of the diagonal cable by making use of the attraction force between the cable and a cylindrical magnet 3 fixed to the main girder 7 and the restricted state is released by making use of the reverse force against the attraction force during vibration to change the vibration mode of the diagonal cable. The restriction and release of vibration are repeated alternately to transfer the energy of the primary vibration mode to a high order and prevent the promotion of vibration and also reduce steady vibrations.

Filed: 1995-09-08
Abstract: PROBLEM TO BE SOLVED: To improve follopwup performance by making the switching means of the target speed of a capstan motor instantaneously changeable by a command and thereby eliminating the necessity of setting stepwise target values. SOLUTION: When setting is changed from one-fold speed to ten-fold speed in the VHS system, the speed switching means 12 having received a command 12 changes the frequency dividing ratio 43 which is impressed on the capstan servo system from '1' to '10'. Then the control system of the capstan is accelerated as it is so operated that the frequency-divided signal accords with the original signal frequency. A tape speed detector 9 catches this speed and causes center frequency calculators 10, 11 to calculates the center frequency disk corresponding to the instantaneous value of the tape speed at this time and, at the same time, causes a frequency calculator 22 to calculate the reference frequency for phase control.
