Title: Production of pitch based carbon fiber
Inventor: NAKAKOSHI AKIRA
IPC: D01F9/14
Filed: 1986-07-01
Abstract: PURPOSE:To enable ready removal of undrawn filaments contained in a tow, by dipping the tow of pitch fibers in a state without tension in a liquid to open the tow. CONSTITUTION:Raw material pitch is melt spun. A binder is then applied to bundle the resultant filaments and give a tow 3 of pitch fibers. The obtained tow 3 of the pitch fibers in a state without tension is then dipped in a liquid to separate into each filament constitution the tow 3 (this operation is referred to as opening). Thereby removal of undrawn filaments contained in the tow 3 is facilitated. The liquid is preferably made in a fluid state and the tow is preferably dipped therein while countercurrently running the tow 3 against the flow of the liquid.

Title: Steering control device for vehicle
Inventor: NAKAJIMA HIROSHI
IPC: B62D6/00
Filed: 1994-06-13
Abstract: PURPOSE:To conduct initial setting of a steering angle with an inexpensive and reliable means in a steering control device for a vehicle. CONSTITUTION:A target steering angle value for a dirigible road wheel being a control object is determined by a target steering angle determining means and an actual steering angle value is measured by a measuring means 60. The measuring means 60 has a changeover switch 62 and detects the steering direction of the dirigible road wheel in accordance with a switching state. When the dirigible road wheel is gradually steered into the neutral direction by a steering angle control means, a position where a switching state of the changeover switch 62 is changed is adopted as a neutral position. In accordance with this, initial setting of the neutral position of a relative steering angle sensor 61 is conducted by a neutral correction means. Steering angle deviation between the actual steering angle value and the target steering angle value is computed by a steering angle deviation computing means, and in accordance with this steering angle deviation, the steering angle control means is driven so as to conduct steering angle control of the dirigible road wheel.

Title: Tamponade of glass liquid for rear cavity of eye
Inventor: HATSUSO MAINAATO
IPC: A61F9/007
Filed: 1993-06-25
Abstract: PURPOSE: To save the removing operation of vitreous humor. CONSTITUTION: This vitreous humor tamponade for the posterior cavity in an eye includes at least one perfluorocarbon which is liquid under normal conditions and, after injection in the eye, changes into the vapor condition as a result of its vapor pressure. Thus, because it is liquid under normal conditions and, after injection in the eye, changes into the vapor condition as a result of its vapor pressure, it is possible to prevent the acute rise of the intra-ocular pressure and to inject new vitreous humor without removing the existing vitreous humor by sucking. Therefore, it becomes possible to inject vitreous humor without such complicated operations as to cut the vitreous body.

Title: Digital magnetic recording device
Inventor: IKEGAMI TOMIO
IPC: G11B20/10
Filed: 1988-06-23
Abstract: PURPOSE:To improve the linear recording density by emphasizing the high band of the reproduction signal a magnetic head and furthermore correcting the waveform distortions via a full band pass circuit. CONSTITUTION:The signal reproduced by a recording medium 1 and a magnetic head 2 is amplified by an amplifier 3 and passes through a low band pass circuit 9 having its emphasized high band. Then said emphasized signal undergoes the elimination of its waveform distortions via a full band pass circuit 5 which corrects the phase characteristics or the delay characteristics equivalent to said phase characteristics and is turned into the digital data by a differentiator 6 and a wavefrom shaping circuit 7. In other words, the output signal of the amplifier 3 has a waveform that has the large inter-waveform interference because said signal has the small high band component. However the high band of the signal is emphasized through the circuit 9. The output signal of the circuit 9 has the small inter-waveform interference and has a waveform that can improve the linear recording density. This waveform has the distortions due to the distortion of the delay characteristics, and this distortion of the waveform can be eliminated through the circuit 5 at its output. Thus the linear recording density is improved and the recording capacity is increased for a digital magnetic recording device.

IPC: G09F9/30
Filed: 1989-06-20
Abstract: PURPOSE: To more easily manage luminance and colors by providing a first panel controlling the passage of red and green picture components and a second panel controlling the passage of a blue picture component. CONSTITUTION: The first panel 1 having a liquid crystal picture element controlling the transmission of the red and green picture components and the second panel 6 where the liquid crystal picture element controls the transmitted blue picture component through the first panel are overlapped. The first panel 1 manages the red and green components by additive color mixture space adjacent technology and the second panel 6 manages the blue component by subtractive color mixture technology. Since the sensitivity of naked eyes for the blue component is low, the smaller resolution and smaller regeneration rate can be given to the picture element array of the second panel compared to those of the first panel. Thus, high display lightness/picture resolution and more satisfactory color reproduction can be obtained.
