Title: Manufacture of base material for singly polarizing optical fiber
Inventor: TAKABAYASHI TSUNEHISA
IPC: C03B37/014
Filed: 1984-09-10
Abstract: PURPOSE:To obtain a singly polarizing optical fiber having stable characteristics with improved productivity by embedding a graphite rod in a core material and pulling it out to pierce a hole for a part having a low refractive index. CONSTITUTION:Fine SiO2 particles contg. a desired dopant are blown on the accurately finished outside of a graphite rod 11 by an external CVD method, and the resulting porous base material is vitrified to form a core material 12. The outside of the core material 12 is ground so that the graphite rod 11 is eccentrically positioned, and the ground core material 12 is coated with a clad material 13 and united to one body. The clad material 13 can be formed by an OVD method, it can be formed by covering the core material 12 with a quartz pipe and collapsing the pipe, or it can be formed by combining both the methods. The graphite rod 11 is then pulled out to obtain a base material 15 for a singly polarizing optical fiber having a hole 14 at a noncentral position of the core material 12. Air, nitrogen or argon is filled into the hole 14, and the base material 15 is heated and drawn under slight pressure to obtain a singly polarizing optical fiber.

Title: Tokamak type nuclear fusion device
Inventor: YOSHIOKA TAKESHI
IPC: H05H1/18
Filed: 1987-07-28
Abstract: PURPOSE:To shorten the recharge period and increase the duty factor by fitting coils having a function to destroy the magnetic face of plasma over the whole plasma when excited to a toroidal device and exciting these coils only in the recharge phase. CONSTITUTION:A high-frequency generator 1 and a launcher 2 constitute a high-frequency driving device feeding the plasma current to plasma 3. Local helical coils 5 making the magnetic face 4 of the plasma 3 ergodic are added to a toroidal device. The coils 5 have a function to partially destroy the magnetic face 4 of the plasma 3 when excited. Multiple local helical coils are used so as to generate multiple helical modes to make the whole plasma ergodic. The degree of the destruction of the magnetic face 4 can be controlled by the current flowing through the coils 5. The plasma enclosing performance, i.e., the degree of the plasma temperature rise when the high-frequency power is applied, can be controlled by the quantity of the current flowing through the coils.

Title: Diversity receiver
Inventor: HOTTA NOBUTAKA
IPC: H04N5/44
Filed: 1990-07-18
Abstract: PURPOSE:To obtain a stable reception picture by adding only an optional setting level to a reception level of an antenna selected at a preceding state so as to provide priority at the comparison of the reception level of each antenna so as to reduce frequency replacement of the selected antenna. CONSTITUTION:Suppose that an antenna selected at a preceding time is an antenna (a) and that a level (l) is to be a setting level added to a reception level of the antenna (a) selected at the preceding time at a level adder circuit 105. When a level of signals 155-157 is lower than the level of a signal 158 resulting from the sum of a level of a reception level signal 154 of the antenna (a) and the level (l), the antenna (a) is selected again. Moreover, when any of the levels of the signals 155-157 is higher than the level of the signal 158 being the sum of the level of the reception level signal 154 and the level (l), an antenna with a maximum level is selected. Thus, since the antenna (a) selected at the preceding time is selected with higher priority by the set level of the adder circuit 105, the frequency of the change in the selected antenna is reduced and the picture is made stable.

Title: Locked-track resetting device of recorded-information reader
Inventor: HOSAKA TOSHIHIKO
IPC: G11B7/085
Filed: 1980-12-29
Abstract: PURPOSE:To release a locked track securely by applying an offset signal with a prescribed level to the servo loop of a tracking servo means once detecting a locked track phenomenon. CONSTITUTION:Once a locked-track phenomenon occurs, a track error signal (a) outputted from an amplifier 8 varies greatly, and a reproduced RF envelope signal (c) outputted from an envelope detector 15 drops in level greately down nearly to zero during the period. This is compared with a reference level by a comparator 16, which generates a comparison output (e) with a high level during the period. Therefore, a switch 19 turns on during this period, and an offset voltage by an amplifier 18 is applied as disturbance to a servo loop through the amplifier 8. As a result, a tracking mirror 12 is driven forcibly to achieve reproduction from a track that it is following up at that time.

Title: System for displaying bus stack cause
Inventor: ABE FUMIHIRO
IPC: G06F3/14
Filed: 1987-07-27
Abstract: PURPOSE:To judge which device makes the access to a common owning bus by displaying the presence of a bus access requesting signal with a visible light, generating the clock signal of a prescribed time width from a clock generating means, giving it to a timing generating means and displaying a bus stack cause. CONSTITUTION:When a bus access requesting signal BRQS is inputted from a central control device or a data channel device to a latch circuit 1, the latch circuit 1 once latches this signal and outputs it as a latch signal LATS to a timing circuit 2. In the timing circuit 2, a connecting and cutting is executed to the latch signal LATS based on a clock signal CK from a clock generating circuit 3. As the result of this connecting and cutting, a timing signal TMGS to be outputted goes to be the signal of the time width determined by the clock signal CK and inputted to a converting circuit 4. In the converting circuit 4, this timing signal TMGS is converted to the visible light, outputted and displayed. Thus, which device executes the bus access can be judged.

Title: Cylinder of magnetic recording and reproducing device
Inventor: SASAKI TAKASHI
IPC: G11B5/53
Filed: 1983-10-11
Abstract: PURPOSE:To increase the allowable range of eccentricity and to shorten the control time of eccentricity when a rotary cylinder is assembled, by forming the cylinder into a right oval column shape and setting magnetic heads on the long axis of the oval column. CONSTITUTION:Two magnetic heads 27a and 27b are set opposite to each other on the long axis of a cylinder having a right oval column shape. The revolving radius (x) at the attachment part of the head 27a is set larger than the shortest revolving radius (y) at another outer circumference of the cylinder in order to reduce the generation of track bending. That is, x=(L1/2-delta)>L2/2>y is satisfied. and then delta<(L1/2-L2/2) is satisfied. Therefore the track bending is suppressed when the eccentricity degree delta is smaller than the difference between the long and short axes of the cylinder. As a result, the allowable range of eccentricity is increased when the rotary cylinder is assembled. Then the control time is shortened for eccentricity.
