Title: Reception reproducing circuit for data transmission system
Inventor: IWAMURA MASAHIRO
IPC: H03M5/16
Filed: 1978-03-13
Abstract: PURPOSE:To ensure an assured deletion even of such common mode noise that exceeds the reference level of the comparator. CONSTITUTION:Output V01 and V02 of comparator 6 and 7 are led to exclusive logic sum circuit 9, and output V0 of exclusive logic sum circuit 9 is used as the reception reproduction output. In such constitution, comparator 6 and 7 respond to the noise exceeding reference level VF when the common mode noise is supplied to 6 and 7, and the noise pulses emerge in the from of output V01 and V02. However, no noise pulse emerges at output V0 since the exclusive logic sum is secured at circuit 9 for the output of comparator 6 and 7. Accordingly, no noise reproduction is carried out.

Abstract: PURPOSE:To automatically judge whether or not a coordinate input operation has been executed by detecting the position of a vibrating input pen from a distance calculated according to the detection signals of plural sensors, back- calculating the distance of the plural sensors from the detected position, and comparing it with the previous calculated distance. CONSTITUTION:When a start signal 38 is outputted from a microcomputer 31, the driving of a vibrating pen 3 and clocking is started by a vibrator driving circuit 2. When the detection signal of vibration made incident from each sensor 6a-6d on a vibration transmitting plate 8 is outputted before a prescribed time is clocked by a timer 33, the position indicated by the vibrating pen 3 and the distance to each sensor are back-calculated, and a coordinate value is calculated. Next, the distance to each sensor is back-calculated on the basis of the coordinate value. The back-calculated distance is compared with the previously calculated distance, and when the values are equal, the value is outputted to an outside circuit as the established value. On the other hand, when the compared values are different, the vibrating pen 3 is left behind on the vibration transmitting plate 8, and a power source cutting operation or the like is operated.

Abstract: PURPOSE:To provide a cushioning material free from harmful gas, easy to incinerate for disposal, reusable for recycling of discarded papers and easy to vary the cushioning action by a method wherein the paper cylinder consisting of discarded papers are cut into pieces of a suitable length and a lidded paper-made case or bag is packed with the cut paper cylinder pieces in a randomly orienting manner. CONSTITUTION:Paper cylinders are cut into pieces of a suitable length and a liner paper-made case 2 with a lid 3 is packed with such cut paper cylinder pieces 1 in a randomly orienting manner by loose arrangement, adhesive attachment or compression molding by a die using adhesive. The cut paper cylinder piece 1 varies in elasticity (cushioning action) and rigidity with the number of times that the paper is wound to form the cylinder and the inside diameter and length of the cylinder. Since there are differences in the elasticity (cushioning action) and the rigidity between the outer peripheral and longitudinal directions of the cylinder, the cut paper cylinder pieces are attached together in a randomly orienting manner to permit the action of cushioning material to be varied. Since discarded papers are used, the cushioning material is economical to manufacture, easy to incinerate for disposal, free from harmful gases and reusable as another material for recycling supply.

Title: Control circuit for semiconductor laser
Inventor: KOISHI KENJI
IPC: G11B7/125
Filed: 1989-02-07
Abstract: PURPOSE:To form the shape of a recording pit symmetric to the center of a recording pulse waveform and to perform recording feasible for signal reproduction without generating time jitter by providing a second modulation stage which performs the optical pulse modulation of the bottom value of the optical pulse waveform and an optical power value between the neighborhood of zero. CONSTITUTION:A modulation stage II 24 performs the optical pulse modulation between a bottom value power 19 holding a semiconductor laser 1 and the optical power value 25 in the neighborhood of zero according to a cooling signal 26. The cooling signal 16 inverts a recording signal 11, and is generated by the AND of a signal delayed for constant delay time by a delay line 27 and an original recording signal. Therefore, the cooling signal 26 can be generated immediately behind the recording signal. Also, the delay time of the delay line is selected by reproducing the recording pit and so as to obtain the minimum time jitter of a reproducing signal. In such a way, the recording pit with shape symmetric to the center of recording pulse light can be formed, and the quantity of time jitter can be reduced by performing the signal reproduction of the recording pit with such symmetric shape, which realizes data recording and reproduction with high reliability on an optical disk.
