Title: Thin film type magnetic head
Inventor: UCHIKURA HIDEAKI
IPC: G11B5/31
Filed: 1983-09-16
Abstract: PURPOSE:To prevent the signal discriminating phase margin from lowering and to obtain a magnetic recording device having a small data error rate, be setting the thickness of a magnetic pole positioned in the forward direction of the running movement to a value of a range smaller than the thickness of another magnetic pole in the backward direction. CONSTITUTION:By setting the pole thickness T3 of a front magnetic pole 30 to about 0.7-0.9 times of the pole thickness T4 of a rear magnetic pole 31, the front half-amplitude level 45 of an isolated waveform becomes smaller than the rear half-amplitude level 46. When recording and reproduction are made with a magnetic head having such magnetic poles, skewness in magnetization for recording is offset by the influence of a demagnetizing field and the peak shift of the reproduced waveform becomes almost positive-to-negative symmetrical. For example, the difference between a peak shift generated by a minimum magnetization inverting interval pattern 53 and another peak shift generated by a magnetization inverting interval pattern 54 larger than the said peak shift approaches zero and the difference Tp11 in the peak shifts becomes considerably small.

Title: Thermal recording material
Inventor: KATOU NORITOMO
IPC: B41M5/337
Filed: 1987-07-08
Abstract: PURPOSE:To obtain a thermal recording material having high sensitivity, imparting a recording image reduced in fading or whitening, reduced in heat resistance fog and having excellent chemical resistance, by using a specific compound as a coupler and using 4-methoxycarbonyloctadecylcarbamoylbenzene as a sensitizer. CONSTITUTION:In a thermal recording material utilizing the color forming reaction between a leuco dye and a coupler, a compound represented by general formula (I) (wherein R is hydrogen, an alkyl group, an aryl group or an aralkyl group) is used as the coupler and 4-methoxycarbonyloctadecylcarbamoylbenzene is used as the sensitizer. The compound represented by the general formula (I) is slightly inferior to heat response or the density uniformity of a developed color image alone but the coupler having strong color developing capacity. Since 4-methoxycarbonyloctadecylcarbamoylbenzene has a high m.p. but high sensitizing effect, said compound is the sensitizer having heat resistant preservability. Both compounds are combined to make it possible to obtain the thermal recording material having high sensitivity and imparting an image prevented from being deteriorated by the fading or whitening phenomenon of an image part.

Title: A/d converter
Inventor: ITOU YUUICHIROU
IPC: H03M1/50
Filed: 1979-12-28
Abstract: PURPOSE:To obtain a high-accuracy A/D converter with an easy production, by making use of the signal delay effect caused by a CCD shift register. CONSTITUTION:The pulse delaying device 1 contains the 1st and 2nd CCDs2 and 3 which carry out a transfer in the opposite direction to each other plus the resistive insulator gate 5 provided between the CCDs2 and 3. The voltage Vb(t) obtained by sampling the analog voltage Va(t) is applied to the terminal P2, and thus a channel extending from the end part of the side of the terminal P2 up to the position corresponding to the sample voltage Vb(t) is caused right under the gate 5. As a result, each transfer path of the 1st and 2nd CCD is short-circuited at the end part S1 of the channel, and thus the control pulse VM given from the control pulse generator MGP and put into the terminal Q1 is delayed by the delay time tauD1 in accordance with the length of the integrated transfer path and then detected at the terminal Q2. This delay time is counted by the counter CNT to deliver the digital quantity to the parallel output terminal OUT.

Abstract: PURPOSE:To prevent an excess fastening and to enable the change at like served time by providing the relief valve strong and adjustable for maintaining in the set pressure on the oil passage by pinching a fastening member with energizing oil pressure to the material to be fastened and by making it freely changeable. CONSTITUTION:The material to be fastened is pinched by pushing a ram 20 down by pushing a pressure handle 16, by raising the oil pressure inside a work cylinder 26 and by advancing a fastening member 18b. In this case it is prevented for the oil pressure to become more than the set value by providing a strong relief valve unit 30 on the drain oil path 32 of the cylinder 26. The relief valve unit 30 changes the position of a center shaft 52 with the rotation of a knob 50, adjusts the energizing force for the stem part 46 of a spring 44 and adjusts the abutting force of the taper part 42 for the valve seat 36. The excess pressure oil is leaked from the drain oil path 32 to oil tank 24 to limit the fastening force. The relief valve unit 30 is changed by loosening a set screw in case the service life of the relief valve unit 30 is exhausted.

Abstract: PURPOSE:To easily discriminate a speaking person by outputting added audio signals from plural speakers based on a control signal by a selective addition means so that a picture display position is matched to sounds at the time of displaying a picture on a television conference terminal. CONSTITUTION:For example, a terminal 6a outputs sounds (b) and (d) and sounds (c) from the left speaker and the right speaker respectively. A sound selective addition and distribution part 26 individually adds audio signals outputted to channels 1 and 2 by picture synthesis information from a control part 27 and sends the results. They are converted to audio codes adapted to lines by audio line processing parts 24a to 24d, and they are multiplexed with a control signal and are transmitted to terminals 6a to 6d. Television conference terminals 6a to 6d distribute the audio signals to right and left speakers to output sounds corresponding to positions of reduced and synthesized pictures. Thus, the audio signal is generated from plural speakers correspondingly to the display picture to give presence.
