Patent JP-S62164223-A (JP)
Title: Track access system
Inventor: BABA HISATOSHI
IPC: G11B21/08
Filed: 1986-01-16
Abstract: PURPOSE:To access accurately and at high speed, by changing the switching mode between the relative position detecting signal and the polarity inverting signal before a beam spot reaches a desired track and therefore damping effectively the shift of a light beam. CONSTITUTION:A counter 10 counts the transition frequency of binarization output signals of a comparator 9 and delivers the switch signal for both changeover switches 16 and 17 when the count value of the counter 10 reaches the half of the set value. Thus the output signal of an inverter 12 is delivered from the switch 17. While the output signal of an inverter 15 is delivered from the switch 16. Thus the switch control of a changeover switch 8 is reversed hereafter to the preceding mode and an adder 14 delivers the quite different output signal. Thereafter the damping signal is applied to a light beam deflecting means 5 to reduce the shift speed of a light beam spot. Thus the light beam spot can follow accurately a desired track after a time point when the counting action of the counter 10 is through.

Filed: 1990-01-12
Abstract: PURPOSE:To eliminate a hysteresis phenomenon by connecting two diodes in series and in the same direction between the joints of a variable resistance and a capacitor and also connecting a trigger element between the joint set between both diodes and a semiconductor switching element. CONSTITUTION:A controlling phase circuit consists of the interlocking variable resistances VR1 and VR2 and capacitors C1 and C2.

The trigger voltage is taken out at the middle point between both diodes D1 and D2 and applied to the gate of a triac serving as a semiconductor switching element of S1 via a diac serving as a trigger element of S2. Thus the trigger current of a positive liquid which controls the positive liquid of the power voltage flows in the direction C1   D1   S2. Meanwhile the trigger current of a negative liquid which controls the negative liquid flows in the direction C2   S2   D2 respectively. Thus no hysteresis phenomenon occurs at all.

Title: Optical communication transmitting cable
Inventor: MURATA HISASHI
IPC: H01P3/00
Filed: 1978-01-25
Abstract: PURPOSE: To prevent the transmitting characteristics of a cable from being deteriorated by changing the core of an optical fiber in a taper shape in the longitudinal  direction of the cable so that a fiber having a smaller core diameter in the optical  transmitting direction may be connected with a fiber having a larger diameter.  
     CONSTITUTION: The optical fiber cores 7, 8 and 9 at the both ends of a cable are gradually reduced in a taper form in the longitudinal direction of the cable. A fiber having a smaller core diameter in the transmitting direction is connected with a fiber having a larger core diameter thereby to constitute an optical transmission passage. Since, in that way, the core diameter of the fiber is enlarged at the back of the  connected portion along the transmitting direction, the loss in transmission can be  reduced to a remarkably low level so that the transmitting characteristics can be  prevented from being deteriorated while being held at a satisfactory level.

Abstract: PROBLEM TO BE SOLVED: To provide a method for easily and rapidly enhancing the refractive index of a desired region in silica glass with high accuracy and also to provide a device used for this method. SOLUTION: This method involves irradiating a desired region 1c in silica glass 1 with at least two X-ray fluxes 2A and 2B incident on the silica glass 1 from at least two different directions so that the X-ray fluxes 2A and 2B cross each other only in the region 1c to subject the region 1c to double (multiple) irradiation with the X-ray fluxes 2A and 2B, wherein each of the X-ray fluxes 2A and 2B has wavelengths within the range of 1.2 to 7.0Å and is capable of exciting K-shell electrons of each of silicon atoms, and accordingly, acting effectively in enhancing the refractive index of the silica glass 1. Thus, the refractive index of the desired region 1c subjected to double irradiation with the X-ray fluxes 2A and 2B, is enhanced as compared with those of the peripheral regions of the region 1c.

Filed: 1990-01-16
Abstract: PURPOSE:To make exact analysis without receiving the influence of an ambient temp. by providing a clean air preparing section of a route separate from the route of a gaseous sample, mixing the clean air which is prepd. in this section and is heated to a specified temp. and the gaseous sample and introducing a gaseous mixture into a detecting section. CONSTITUTION:The gaseous sample is sent from a suction port 1 through a needle valve 2 to a mixing point 9. On the other hand, the air is sent from a suction port 3 through an air pump 4 and a needle valve 5 and is cleaned by an air filter 6. The cleaned air is heated by a heater 7. The clean air passed through the clean air preparing section 8 and the gaseous sample are mixed at the mixing point 9 and the gaseous mixture is introduced to a gaseous component detecting section 10. The detected gaseous components are recorded by a recorder 12. Since the gaseous sample is not directly heated in a piping, the cracking by the heating is prevented and the detection section does not receive the influence of the ambient temp. The exact analysis is, therefore, carried out.
