Title: Method for applying foresight control to differential preferential type control system
Inventor: KADOSAKI TOYOFUMI
IPC: G05B13/02
Filed: 1998-03-09
Abstract: PROBLEM TO BE SOLVED: To make it possible to apply foresight control to a differential preferential type control system of which control parameter has been already known. SOLUTION: State feedback gain F1 is calculated from a differential preferential type PID parameter (S4). An error signal and an output to be controlled are added to the quantity of a state to constitute an extended error system (S5). The coefficient matrix Φ, G, GR of the extended error system is calculated (S6). Then an evaluation function including an error term and a foresight input term is determined and a foresight gain F1 R for minimizing the evaluation function is calculated (S10). Consequently a foresight control function can be added to the differential preferential type PID control system.

Title: Reducing method for unused pad
Inventor: AKAISHI MICHIMASA
IPC: H05K3/00
Filed: 1991-03-20
Abstract: PURPOSE:To shorten the work time, and also, to decrease the miss by detecting automatically an unused pad without executing a manual work, and reducing automatically a size of the detected pad. CONSTITUTION:A CAD system is constituted of an input device 1, an output device 2, a storage device 3 and a computer 4. In such a state, by putting an ASC cord to each of parts pins which a printed board designed by the CAD system has, and replacing the parts pin having an unused pad with an unused ASC cord 33 in which the pad diameter is small, a reduction processing of the pad is executed in the CAD system. In such a way, as for the parts having an unused pad in the CAD system, the pad diameter is reduced by replacing the ASC cord, therefore, the reducing work of the pad becomes a work in the CAD which does not necessitate a person's help. Accordingly, the work time is shortened, and also, a miss decreases, and the yield of the printed board can be improved.

Title: Manufacture of polyurethane foam
Inventor: KUMASAKA SADAO
IPC: B29C39/42
Filed: 1987-03-12
Abstract: PURPOSE:To prevent occurrence of scorch phenomenon and a fire by a method in which after foaming stock solution has been mixed and agitated, it is discharged in the groove type conveyer running continuously and is foamed, whereby the polyurethane foam with objective length is formed, and said foam is introduced into a reduced pressure-chamber, and after the pressure in the chamber has been reduced for a specified time, it is restored to normal pressure. CONSTITUTION:Foaming raw material is discharged in the groove type conveyer 4 running continuously from a nozzle 1, and thus polyurethane foam is produced. The polyurethane foam having been cut, it put in the pressure reduction chamber 7 with a suction valve 5 and a pressure reducing valve (deaeration) 6, and said chamber is sucked to 200mmHg by a vacuum pump. After this reduced pressure-condition has been kept for 15min, the pressure in said chamber is restored to normal pressure. The polymerization reaction heat generated in foaming process is not confined inside, and since a part of said heat is diffused outside and is drawn out, the occurrence of scorch phenomenon and a fire may be prevented. When the reaction heat is drawn outside, since said heat is uniformly diffused in the foam, the polyurethane foam with uniform property may be obtained. Further, without using olefin as auxiliary, the polyurethane foam with high expansion ratio may be obtained.

IPC: A61B6/00
Filed: 1999-03-04
Abstract: PROBLEM TO BE SOLVED: To release constraints on design and to expand the degree of freedom in a device movable mode by providing plural devices which receive a radiation as visible light and pick up an image and distributing the visible light to plural image picking up means without making it parallel beams of light once. SOLUTION: When exposure by a radiation source is performed, X-rays transmit an object to be detected and converted into an I.F. (image intensifier) output image by an I.I. part 4, and the I.I. output image is made to pass through a post-lens group 11 and reflected by 90o by a movable distributed mirror 14. The X-rays pass through a pre-lens group 13, are led to the secondary lens 8a of an I.I. indirect camera 8 and are formed on the camera 8 by the lens 8a. Thus, it is possible to realize a form that distributes an I.I. output optical image to a TV camera 7 and the camera 8. Because an image pickup device uses a mirror as both for a folded mirror and a mirror for distribution by adopting the form, the device can be made small-sized.

Abstract: PURPOSE:To stabilize operation and to enhance reliability by using a signal generator, projecting testing light whose intensity is modulated at a light source, detecting the received output by using the signal generator in synchronization, and obtaining the intensity of the response light. CONSTITUTION:As a light source 1, a semiconductor laser characterized by excellent linearity in driving current and optical output is used. A periodic signal of 1kHz is generated in a signal generator 4. A driving current of the light source 1 is modulated. Testing light 8 which is modulated in intensity at 1kHz is formed and projected on a material to be measured 5. As response light, the transmitted light is selected, and the light is received with a photodetector 2 comprising a photodiode. The received signal is detected in a synchronous detector 3 with the signal of the signal generator 4 as a reference signal. Thus the intensity of the response light is obtained. The light transmitting characteristic of the material to be measured 5 can be measured. Since the selectable range of the modulating frequencies is wide, the frequency having the least noise can be selected and the synchronous detection can be performed. Thus, the noise removing effect can be enhanced.

Abstract: PURPOSE:To prevent the variance of a DC level by inverting a prescribed one of (n) bits according to the state of array of 1 and 0 of (n) bits when an m-bit signal is code-converted into an n-bit signal. CONSTITUTION:An m-bit input signal (A) is converted into an n-bit signal which is previously stored in a memory 31, the n-bit signal is converted by an NRZI converter 34.

The continuous bit numbers K of 0 can be reduced even in case the n-bit signal strings are arrayed. Thus the code conversion is possible with a small range of cumulative charge variance DSV and large suppressing effect of DC variance.
