Title: Method for evaluating life of heat resisting steel
Inventor: FUKUDA KIYOSHI
IPC: G01N3/32
Filed: 1988-11-25
Abstract: PURPOSE:To easily decide whether the holes formed between the grain boundaries of the metal of an object to be inspected exceed a life consumption region or not with high accuracy by measuring the above-mentioned holes with lapse of the service time and previously collating the holes with a predetermined master curve when the formed holes expand. CONSTITUTION:The ordinate of the master curve for predicting the material life in the case of evaluating the life of a heat resisting steel, such as CrMoV steel, indicates the peripheral length of the holes formed between the grain boundaries of the metal and the grain boundary width and the absissa indicates the life consumption, respectively. The results of the analyses to make image processing of the holes formed between the grain boundaries of the object to be inspected are drawn by a replica method in this detection method and are plotted. The holes gather at a point A and a point B if the service time is relatively short. The holes transfer and progress to a point C and a point D beyond the material life threshold line (the broken line of a vertical line) when the service life is long. The sizes of the holes 1a, 1b, 1c grow as the service time passes by in the beginning of the measurement. The holes connect to each other between the grain boundaries and expand like the width W.

Title: Label printer
Inventor: SATO TAKASHI
IPC: B41J29/48
Filed: 1991-11-13
Abstract: PURPOSE:To obtain an easy adjustment of sensibility of a sensor which detects a label position detecting mark in a label printer which prints and issues a label such as a barcode to be attached to goods and so on. CONSTITUTION:When an indication for sensibility adjustment is given by an indication input processing means 17, a transfer processing means 19 makes a transfer part 13 transfer a complex successive label paper 15 by a length that includes a label position detecting mark. In this while, a sensor output reading processing means 20 reads an output value given by a mark detecting sensor 14 and stores it. A sensibility set processing means 22, based on a change of the output value, sets an output value of the mark detecting sensor 14 which is used as a threshold value in a detection of the label position detecting mark at a time when a label is issued normally. Thus a label issue controller 23 can detect correctly the label position detecting mark by means of the set value.

Filed: 1998-10-20
Abstract: PROBLEM TO BE SOLVED: To reduce stimulus Brillouin scattering by, related to an optical fiber system, comprising an integral internal void synthesis reflector, to which tuning voltage and dither signal are added for tuning in broad band. SOLUTION: A semiconductor laser 10 which allows broad band tuning comprises a gain section 12 and an internal void synthesis reflector section 14, and a current driver 16 supplies a current to the gain section 12 for generating an output signal 20. A forward bias DC voltage is supplied to the synthesis reflector section 14 from a bias source 18 for controlling a phase of an optical field in the void inside laser, thus carrier frequency of an output signal is roughly adjusted. Further, the output signal is combined to a transfer medium having tendency to generating stimulus Brillouin scattering(SBS). In order for reducing the SBS, a dither signal of relatively low frequency and low voltage is further added to the synthesis reflector section 14. The spectrum of the output signal is widened for increased SBS threshold.
