Title: Method for measuring heating hysteresis
Inventor: SASAKI HIDEYUKI
IPC: G01K7/36
Filed: 1988-10-31
Abstract: PURPOSE:To measure an accurate heating hysteresis without exerting thermal effect on a part to be measured by optically detecting the magnetical change of the ferromagnetic membrane formed to the surface of an object to be measured. CONSTITUTION:A ferromagnetic membrane 2 composed of Gd-Co is formed on a substrate 1 such as an IC board and an electromagnetic coil 3 is allowed to approach the substrate 1 to be moved on said substrate to magnetize the membrane 2 in the same magnetizing direction. Next, the substrate 1 is heated by electron beam 4 and, after the magnetizing direction of the heated region is reversed, laser beam polarized in a predetermined direction is allowed to be incident to said region. Since the plane of polarization of the incident beam 5 is optically rotated on the membrane 2, the plane of polarization of reflected beam 6 is different from that of the incident beam 5 and, therefore, the reflected beam 6 is detected by a photodetector to measure a heating hysteresis.

Filed: 1995-10-20
Abstract: PROBLEM TO BE SOLVED: To surely fix a photographic transfer sheet to an enameled plate by making the maximum temp. in baking the transfer sheet lower than the baking temp. in cover coating. SOLUTION: A base metallic plate is formed into a specified shape, surface- treated and plated with Ni, the surface is grounded with a glaze as a black ground coating, and the glaze is dried and baked. A glaze as a white cover coating is then applied and baked at about 780 deg.C (T1) to form an enameled plate. A photographic transfer sheet is then stuck on the enameled plate with water, gradually heated as the first-stage baking and baked at 500-600 deg.C. Subsequently, the temp. is raised continuously and drastically without returning the temp. to ordinary temps., and baking is conducted at 740-760 deg.C (T2). Since the maximum baking temp. T2 of the color transfer sheet is made lower than the baking temp. T1 of glaze, the deterioration of the cover coating surface is prevented, and extremely delicate picture, pattern, etc. are reproduced.

Title: Method for encoding picture
Inventor: KONDO TETSUJIRO
IPC: H04N19/196
Filed: 1993-10-04
Abstract: PURPOSE:To perform encoding without deteriorating the compression efficiency by discriminating the block activity (BA) on the prescribed block of the hierarchy data and setting the threshold value being the discrimination reference of the division processing for the low-order hierarchy data based on the degree distribution for the BA. CONSTITUTION:A generation information amount control part 40B of a picture encoder decides a threshold value TH adapted for the data to be processed by inputting input picture data. In a hierarchy encoding encoder part 40A, the optimal control value which is decided so that the input picture data are efficiently encoded is sent to the encoder. Thus, the time delay to be generated by the accurate generation information amount control and the feedforward type buffering is eliminated. When the picture data are divided into plural hierarchy data with dissimilar resolution reflexively in succession and is encoded, the BA is discriminated on the prescribed block of the hierarchy data excluding the highest order hierarchy data with the lowest resolution. Then, the threshold value is set from the distribution of the block degree corresponding to the BA and the transmission amount is increased and decreased to prevent the deterioration of the compression efficiency.

Abstract: PURPOSE:To always improve the trailing characteristic of a logic circuit effectively by providing a differentiating capacitor for supplying a conduction drive signal to a base of a pull-down transistor(TR) and a circuit feeding back a potential at an emitter follower output to a base of the pull-down TR. CONSTITUTION:A base bias condition of pull-down TRs Q21,Q22 is changed in response to a load condition of an output of emitter followers 11, 12 and when a residual charge of an external load is much, the residual charge increases the base bias level to increase the conduction drive level of the TRs Q21, Q22. Moreover, the potential at the output of the emitter followers 11, 12 is fed back to the base of the pull-down TRs Q21, Q22 in terms of DC and a charge/discharge current able to be supplied as a conduction drive signal to the base of the pull-down TRs Q21, Q22 from differentiating capacitors C1, C2 is increased at the transient state detection. Thus, the leading characteristic of the logic circuit using the emitter followers 11, 12 as the output stage is always effectively improved independently of the external load.

Abstract: PURPOSE:To eliminate the need for forming a running control program at each drive pattern by adopting the constitution such that path information is provided to each branch and stop point of a running line and the running path is discriminated by reading the path information. CONSTITUTION:When an unmanned truck 1 continues running and a branch point 41 exists, a path information reader 11 of the track 1 starts the read operation by a start mark 42 and reads the path information from an informa tion label 43. The read path information is compared with a running path data stored in a running path data memory 12 formed in advance, the branch direc tion is judged and the track 1 is driven to the branch path. Then, when a stop point 44 exists, the reader 11 is started by a start mark 45 to read the path information of the information label 46. The path information is compared with the drive data stored in the memory 12 to judge the presence of the stop point. Thus, the forming of the running control program at each running pattern is not required at all and the track is driven autonomously by a command of only the stop point independently of the start point.
