Filed: 1987-10-05
Abstract: PURPOSE:To suppress the generation of defect by finely correcting the working dimension by measuring the working error for each succeeding work and outputting a working error correcting instruction into a machine tool independently of the number of the succeeding works on the basis of the result of the measurement. CONSTITUTION:When the working error for a work 1 in the measurement by a measuring device 3b is continuously set in n-times into the +OK region between the + correction boundary value LB and an upper limit tolerance LD, a correction value A0 is outputted into a machine tool 2a.

When the measurement of the working error of the succeeding works 1b-1e is completed. the +LB is lowered and returned, and when the measurement is continued, similar processing is repeated from the first process, and the next work (white circle) among the succeeding works is set close to the OK region side. Thus, the generation of defects can be suppressed.

Title: Installation of reflecting part of label and method to recover reflection brightness
Inventor: NAKANISHI YASURO
IPC: G09F13/16
Filed: 1995-08-22
Abstract: PROBLEM TO BE SOLVED: To easily recover reflection brightness by covering a stained part with a freely mountable-demountable band-like reflecting part, or replacing it. SOLUTION: A band-like reflecting part is made freely mountable and demountable. For example, a drawing (e) shows that the reflecting part is expanded into a freely restorable reflecting belt 5, and a pillar B can be fastened by being sandwiched by restoring force. In a drawing (c), a reflecting sheet 6 is wound round the pillar B, and is fastened by being partially stuck by an adhesive 1 sticking to the end. In this way, since it can be fastened from the side differently from a conventional one, needless to say a post cone, even a thing like a guide rail can be easily and quickly mounted and demounted. This method can be applied to all columnar ones, even in a square shape or even in a conical shape even if the pillar B is not a column.  Therefore, not only reflection brightness of a stained part can be recovered but also a part unreflected so far can be newly and easily made reflectible.

IPC: H04J13/00
Filed: 1988-10-06
Abstract: PURPOSE:To facilitate the synchronization decision, and also, to shorten the time required for pull in by constituting the title system so that the larger a correlation value reproduced from an intermediate frequency signal is, the smaller the sliding width becomes. CONSTITUTION:A receiving modulation signal which is brought to spectrum diffusion modulation and a pseudo random signal from a pseudo random genera tor 1 are applied to a correlator 2 and converted to an intermediate frequency signal, this intermediate frequency signal is applied to a data reproducing part 6 and receiving data is reproduced. From a correlation value reproducing part 4, a sliding width control part 5 is controlled, and when a correlation value reproduced by the correlation value reproducing part 4 is small, sliding width is enlarged, and when the correlation value is large, the sliding width is made small. In this state, when the correlation value becomes maximum continuously, a synchronization deciding part 3 decides it to be a synchronizing state, and a control state in the sliding width control part 5 is maintained. In such a way, even if pull in is executed in an initial state that the correlation value is small, the synchronization can be executed at a high speed.

Title: Urine taking pad for male
Inventor: WADA ICHIRO
IPC: A61F5/44
Filed: 1997-09-17
Abstract: PROBLEM TO BE SOLVED: To provide a urine taking pad for the male which is easily attachable and detachable to and from a penis and does not allow the easy removal of the penis. SOLUTION: A bag body 1 is formed of a laminate formed of an inside sheet, an absorption core and an outside sheet. The aperture of the bag body 1 is provided with a planar elastic member 8. When a user pinches the elastic member 8 with the fingertips and applies force F thereon, the elastic member 8 is deformed by buckling to open the aperture 2. When the user inserts the penis into the aperture 2 and removes the force F, the penis is adequately pressed by the elastic restitutive force of the buckled and deformed elastic member 8 and is prevented from removing. Since the pressing force by the buckling and deforming of the elastic member 8 is small, the compression feel of the penis is small and the mounting of the single hand is possible as well.
