Title: Digital color demodulator
Inventor: KOBAYASHI REIICHI
IPC: H04N9/66
Filed: 1986-08-26
Abstract: PURPOSE:To demodulate a color even when a sampling clock is not locked in phase to a burst signal by driving all the respective digital processing circuit parts by an internal system clock formed of the second PLL circuit. CONSTITUTION:The second PLL circuit 15 outputs the internal system clock pulse of 910FH locked in phase to an H pulse outputted from a timing circuit 16. Such an internal system clock pulse is supplied to the respective part circuits excluding the first multiplier 20, the second multiplier 21 and the first PLL circuit 14 of the respective part circuits as a driving pulse. Thus, since the system is operated by the clock signal of 910FH outputted from the PLL circuit locked in phase to the horizontal pulse, one line is 910 samples and a vertical correlation can be obtained in picture data. An A/D converted sub-carrier signal is multiplied by a chrominance signal C, thereby, a color difference signal is demodulated. Thereby, the color demodulation can be attained even when the sampling clock is not locked in phase to the burst signal.

IPC: A61G5/04
Filed: 1994-08-24
Abstract: PURPOSE: To provide a motor-driven unit for wheelchair capable of surely transmitting a high driving force from a driving roller to a wheel. CONSTITUTION: This motor-driven unit for wheelchair which drives rotatably the wheel by transmitting the rotation of a driving motor 59 to the wheel of a wheelchair via the driving roller 70 supports at least the driving roller 70 so as to turn in the circumferential direction of the wheel for a main body part (unit main body), and also, it is provided with a tortion spring (pressing means) 58 to press the driving roller 70 on a neutral position.  By employing such constitution, a high frictional resistance force is generated between the driving roller 70 and the wheel when the high driving force is required for the driving roller 70, and when such frictional resistance force exceeds the pressing force of the tortion spring 58, the driving roller 70 is turned in a prescribed angle range and it bites in the wheel, therefore, slippage between the driving roller 70 and the wheel can be prevented from occurring, and the high driving force can surely be transmitted from the driving roller 70 to the wheel.

Inventor: OSADA HIDEKI
IPC: C03C10/00
Filed: 1999-07-14
Abstract: PROBLEM TO BE SOLVED: To improve the specific Young's modulus of glass and also to increase the productivity of a glass substrate by specifying composition ratios of SiO2, Al2O3, MgO and ZrO2 being main components. SOLUTION: The composition range of main components are kept in 35.5-55% SiO2, 10-30% Al2O3, 10-30% MgO and 3.2-5.8% ZrO2 by weight ratio. When SiO2 is less than 35%, melt property becomes worse, and when SiO2 is more than 55%, crystal is hardly precipitated. When Al2O3 is less than 10%, a precipitated crystal is small and strength is low, and when Al2O3 is more than 30%. melt temp. becomes high and the glass is liable to devitrify. When MgO is less than 10%, the chemical durability of a glass matrix phase is not improved, and when MgO is more than 30%, other crystalline phase is precipitated and desired strength is difficult to obtain. When ZrO2 is less than 3.2%, sufficient crystalline nucleus is hardly formed and fine and homogeneous crystalline structure is not obtained.  Also, when ZrO2 is more than 5.8%, melt temp. becomes high and also the glass is liable to devitrify and melt formation becomes difficult.

Abstract: PURPOSE:To record and reproduce an image having no break and to improve a learning effect by recording in order the image of a camera by plural VTRs for a preset recording time each by a magnetic recording and reproducing device VTR control device. CONSTITUTION:The image of a camera 4 is recorded by setting in advance a recording time on the timer provided on a VTR control device 7 and making a VTR 1 in a picture recording sate. On completion of the set time, the VTR 1 is stopped, rewound by the recording time and made in a reproduction standby state. A VTR 2 then starts a picture recording at the time when the VTR 1 stopped its recording, performing the same motion as the VTR 1 thereafter and moreover a VTR 3 is also controlled by a device 7 so as to perform the same motion. Thus the image having no break is recorded and reproduced and by using it for learning, the effect is increased.
