Title: Optical recording medium
Inventor: WATANABE YUJI
IPC: G11B7/24
Filed: 1993-05-24
Abstract: PURPOSE:To improve the recording sensitivity and to suppress changes in film properties of a recording layer or deterioration of performance of an optical recording medium consisting of a substrate, recording layer, and dielectric layer by incorporating an oxide and carbon into the dielectric layer. CONSTITUTION:The dielectric layer used for this recording medium consists of at least an oxide and carbon so that the inner stress of the dielectric layer is decreased. Thereby, the obtd. optical recording medium has little mechanical change such as warpage. Further, excellent adhesion strength with the recording layer is obtd. so that peeling of films or cracks can be suppressed. By an observation of the dielectric film such as SiO2 with addition of carbon (SiO2-C) by TEM(transmission electron microscope), it is found that the film is a uniform amorphous film and has no grain boundary which are apt to become the passage for oxygen and water. Thereby, changes of film properties or deterioration of performance of the recording layer can be suppressed.

Title: Pipe heating universal inner diameter
Inventor: UCHIDA YUJI
IPC: F16L11/00
Filed: 1989-05-17
Abstract: PURPOSE:To obtain a pipe which inner diameter is universal with simple structure and without over expansion in the longitudinal direction by providing an inner tube folded in the circular direction inside a tubular supporting material, and providing a linkage for connecting them movably in the radial direction at least. CONSTITUTION:When an inner tube 22 is supported by a tubular supporting material 21, the inclination angle alpha of a link member 30 from a ring 24 is decided so that a distance between the ring 24 and the tops 26 is the predetermined distance (a) to decide the predetermined inner diameter. Next, at the time of enlarging the inner diameter of the inner tube 22, when the link member 30 is inclined more so that the inclination angle becomes the small inclination angle beta, the distance (b) between the ring 24 and the tops 26 is narrowed and while the space between the respective tops 26 in the circular direction is enlarged. Consequently, the inner tube 22 is folded more non-densely and the inner wall 29 is expanded to the outside by the folded part to form the inner tube 22 having a larger inner diameter E. At the time of reducing the inner diameter, the inclination angle of the link member 30 reversely enlarged to fold the inner tube densely, the inner wall 29 retreats to the radial inside to reduce the inner diameter.

Abstract: PURPOSE:To simplify the operation of the device and the constitution of the circuit thereof by providing a current voltage converting circuit, a phase-shifting circuit and a voltage controlling amplifier and thereby changing the phase of the self- oscillation circuit of a crystal oscillator. CONSTITUTION:A position feedback oscillation circuit is formed of the crystal oscillator 2, a current voltage converter 4, a phaser 7 and the voltage controlling amplifier 8. The driving voltage Vout of the crystal oscillator 2 turns to be an effective driving voltage Vd through a rectifier 10. Meanwhile, so as to set the effective value of the driving voltage Vout of the crystal oscillator 2, the voltage Vref of a reference voltage source 11 and the effective driving voltage Vd of the crystal oscillator 2 are compared with each other by an error voltage comparator 12. A comparison signal Vc is fed back to the voltage controlling amplifier 8, whereby the driving voltage Vout of the crystal oscillator 2 turns fixed. By making the input impedance of the current voltage converter 4 lower than the impedance of the cystal oscillator 2 at the time of resonance thereof, an output voltage Vm proportional to a current running to the oscillator 2 is obtained. By such a constitution, the operation of the device, as well as the constitution of the circuit thereof, can be simlified.

Title: Spindle member for air fine spinning frame
Inventor: IDENO KOJI
IPC: D01H1/115
Filed: 1997-05-13
Abstract: PROBLEM TO BE SOLVED: To provide a spindle capable of increasing the yarn strength of spun yarn in an air fine spinning frame for carrying out spinning by a spindle member and a turning air flow. SOLUTION: Since the tip part of a spindle 1 is rounded into a spherical shape and the surface of the spindle comprises a ceramic member lustered by polishing, the rotation of yarns by a turning air flow from a jetting nozzle (n) is smoothed at the tip part 3a of the spindle 1 and an unreasonable force is not applied to the yarns when sucked in the spindle and the winding of the yarns on a yarn bundle and sucking in the spindle 1 are performed while maintaining stable tension. Consequently yarn strength and physical properties of yarn are both improved and reducing effects on end breakage during spinning are obtained.
