Title: Impact testing apparatus
Inventor: NISHIMURA TSUKASA
IPC: G01N3/30
Filed: 1987-08-25
Abstract: PURPOSE:To obtain highly accurate destruction data, with the suppression of variations in the speed of a piston under a load, by controlling the speed of an actuator directly from a speed setting signal when a deviation is large between a position setting signal and a displacement signal. CONSTITUTION:An output of a speed sensor 8 for detecting a moving speed of an actuator 1 is inputted into a servo amplifier 3 through a speed amplifier 9. When a deviation is large between an output of a displacement amplifier 6 and a position setting signal, a non-linearity circuit 7 outputs a speed setting signal as intact to keep the moving speed of the actuator 1 constant. During the period, the actuator 1 impacts a sample 2 to apply a load on the actuator 1. After the actuator 1 impacts the sample 2 to break, as it approaches a stop position, a deviation becomes smaller between the output of the displacement amplifier 6 and the position setting signal. Thus, the non-linearity circuit 7 outputs a low-level voltage proportional to the deviation to make the actuator 1 slow down which approaching the stop position.

Title: Magnetic recording and reproducing device
Inventor: HIROSE KOICHI
IPC: G11B20/02
Filed: 1985-09-27
Abstract: PURPOSE:To attain field recording with less provision of delay lines by recording a recording signal and a signal being the result of the said recording signal delayed by 1/2H in recording a field signal on two tracks at the same time and reproducing the two signals at the same time at the reproduction. CONSTITUTION:A signal reproduced by a magnetic head 18 has the same waveform as the signal reproduced by a magnetic head 17 and delayed timewise by 1/2H. Thus, in switching two signals at each field, generation of skew is prevented and a changeover switch 27 is changed over to the X position contact and two outputs of reproducing processing circuits 28, 29 are switched alternately by a changeover switch 31 at each field. However, a flicker takes place at a large vertical luminance change with the simple changeover of the signal delayed by 1/2H. In order to compensate it, the signal is summed with the information before 1H to blur the vertical profile equivalently. Thus, the number of delay lines is reduced and the cost of a recording and reproducing device is reduced.

The man-hours are drastically reduced and particularly the drum is adequate for mass production. The range of material selection is widened and the defects intrinsic to the materials are ameliorated. In addition, even the materials which are unusable hetetofore are usable and, therefore, the effective utilization of resources is made possible thereby reducing the cost. Further, the drum may be enjoyed as interior goods and the range of use may be widened.

Filed: 1992-08-10
Abstract: PURPOSE:To suppress the disturbance by stray light and to assure a bright image of a high contrast even in a bright place by providing black stripes in the parts of the rear surface of a lens sheet where projecting light cannot arrive. CONSTITUTION:A base fabric 3 having a light absorptive layer 4 is stuck to the rear surface of the light reflective base material sheet 2 and a lenticular lens sheet 1 consisting of soft plastic is laminated on the surface thereof. The black stripes 5 are provided in the parts on the rear surface of this lens sheet 1 where the projecting light cannot arrive. The stray light of the sunlight, lamp light, etc., is made incident at an angle larger than the angle of the projecting light on the screen and, therefore, the stray light is gathered by the lenticular lenses on the surface to the positions opposite to the concave parts of the lenses and is absorbed in absorption patterns. On the other hand, the projecting light is made incident on the screen from nearly the front surface of the screen and is, therefore, condensed to the positions opposite to the convex parts by the lenticular lenses on the front surface, by which the projecting light is reflected and diffused and is made visible as a video.
