Abstract: PURPOSE: To execute recording or reproducing while stably executing control of an optical system, such as focus servo and tracking servo, by providing a side where the light of a mask layer is incident with a half-reflection layer. CONSTITUTION: This optical recording medium 10 is constituted by successively laminating the half-reflection layer 14, the mask layer 12 and a recording layer 13 on a transparent substrate 11. As a result, the side of the mask layer 12 where the light is made incident is provided with the half-reflection layer 14 and, therefore, the irradiation light of the optical recording medium 10 is partly passed and partly reflected by the half-reflection layer 14. The control signals of the optical system for recording or reproducing are consequently made possible by this reflected light. Then, the quantity of the reflected light for detecting the control signals of the optical system is made larger than heretofore and, therefore, the control of the optical system, such as focus servo and tracking servo, is stably executable.

Filed: 1983-04-14
Abstract: PURPOSE:To obtain a sample having a constant weight readily, by varying the ratio between the length of openings, through which the sample at an arbitrary radius from the axial center of a rotary body is selectively passed, and the total length of a circumference, thereby performing the reduction at an arbitrary ratio accurately. CONSTITUTION:A sample feeder 9 is moved on a scaled supporting rod 8 and fixed at a sample falling position corresponding to a reduction ratio. Then, a turn table 2 is rotated by a motor 5, and a sample is inputted into the feeder 9. Then the sample falls through a lower end 12 and collected by a receiving pan 11 through openings 1 and 10. The ratio of the sample, which falls to a position separated by a radius (r) from an axial center Ao, becomes the ratio between the sum of the lengths of arcs on the opening 1 and the total length of a circumference. When both ends 1c and 1d of the opening 1 are made parallel with a central line 15, said ratio is continuously varied in the direction of the radius. By moving the feeder 9, the specified amount of the sample can be fed at an arbitrary reduction ratio.

Filed: 1997-03-19
Abstract: PROBLEM TO BE SOLVED: To provide a method for producing a compound membrane by which the compound membrane having a prescribed composition ratio and good crystallinity can be stably produced. SOLUTION: A substrate 100 is placed in a reaction room 1, and heated to a prescribed temperature. A TlBaCaCuO membrane is grown on the substrate 100 by supplying Tl, Ba, Ca, Cu and O from a Tl-evaporating source 7 and a target 5 to the substrate 100. The TlBaCaCuO membrane is crystallized whenever every block having a laminar structure is formed. The evaporating amount of the Tl by heating is large in a incomplete block under construction and thereby the evaporating amount of the Tl is changed according to the proportion of the uncrystallized region on the surface. The evaporating amount of the Tl by the heating is small in the complete block after construction and nearly constant. The membrane growth is stopped for a constant period whenever each of the blocks is formed and the charging amount of the Tl is regulated according to the forming process of the block.

Title: Thermosensitive recording material
Inventor: TERANUSHI HIRONARI
IPC: B41M5/26
Filed: 1990-03-16
Abstract: PURPOSE:To obtain a thermosensitive recording material with satisfactory coloring sensitivity and almost free from texture fog by adding at least, one type of specific diester compound to a thermosensitive coloring layer. CONSTITUTION:A thermal recording material consists of a thermal coloring layer containing a colorless or pale electron-donative dye precursor and an electron-receptive material which allows dyeing through reaction with the dye precursor formed on a support. The thermosensitive coloring layer contains at least one type of a diester compound shown by formula (I). If the compound of formula (I) is used as a sensitizer, the sensitizer becomes a medium and a colorless dye and a color developer form a coloring compound rapidly during heating process, because the sensitizer itself melts speedily due to heat and also thermally melts rapidly and melts at low saturation point with the colorless dye and the color developer. Subsequently, the sensitization effect obtained is significant. Thus the consistency of a developed color during recording process is high, and an obtained thermosensitive recording material demonstrates a high coloring sensitivity.

Title: Sonic velocity measuring method
Inventor: NAKABACHI NORITOSHI
IPC: G01H5/00
Filed: 1987-03-20
Abstract: PURPOSE:To measure the sonic velocity of the fluid in piping with high accuracy without making contact with the fluid, by a method wherein an ultrasonic wave is allowed to be obliquely incident from the outer wall of the piping and the phase speed and group speed caused by the ultrasonic wave of the pipe wall part at the time of measurement are measured and operated according to a specific formula. CONSTITUTION:After ultrasonic transmitter-receivers 1, 2 are respectively fixed and mounted to piping 3 on the upstream and downstream sides thereof along an ultrasonic wave propagation line, an ultrasonic wave is allowed to be obliquely incident from the outer wall of the piping 3 to measure the phase velocity Vp and group velocity Vg due to the ultrasonic wave of the pipe wall part at the time of measurement. Next, almost simultaneously with measurement, the differences DELTAtu, DELTAtd between the times before the ultrasonic waves respectively oscillated from the upstream side to the downstream side and from the downstream side to the upstream side respectively propagate through the pipe wall or the fluid in the piping to be received and the times before the ultrasonic waves propagate through the fluid in piping over N-processes (N=2, 4, 6...) to be received are respectively measured. Subsequently, on the basis of these measured values, a preliminarily specified predetermined function, that is, formula is operated to make it possible to specify the sonic velocity C of the fluid 4 in the piping. By this method, the sonic velocity of the fluid can be measured with high accuracy without making contact with the fluid.
