Title: Sleep detector
Inventor: SAKUMA TAKASHI
IPC: A61M21/02
Filed: 1992-02-04
Abstract: PURPOSE:To detect the existence of a person with no contact and to judge whether the person is asleep or awaken only when the person is existent. CONSTITUTION:An infrared sensor 1 detects infrared rays radiated from a man M and obtains an output at a level corresponding to the amount of infrared rays made incident. The output of the infrared sensor 1 is detected by a level detection part 3. When the output level of the infrared sensor 1 detected by the level detection part 3 is higher than a prescribed level, a noise component is removed from the output of the infrared sensor 1 by a noise removal part 4. Further, the output of the noise removal part 4 is differentiated by a differential arithmetic part 5 so as to calculate the strength of body action. A fuzzy arithmetic part 6 judges the asleep/awaken state by applying a prescribed membership function to the strength of body action.

Title: Parallel stuff data correction circuit
Inventor: SAKAMOTO HISAMITSU
IPC: H04J3/07
Filed: 1990-01-31
Abstract: PURPOSE:To suppress power consumption low by providing a stuff insertion detection circuit, a readout counter, a counter calculating rearrangement mode and a circuit replacing a data in parallel number (n) unit depending on the count of the counter. CONSTITUTION:A phase comparator 11 compares a phase of a write counter 6 with that of a readout counter 12 of a memory with slowest stuff insertion and outputs a stuff designation signal (e). A counter inhibit signal 13 outputs the stuff designation signal (e) and a signal g(n-set) designating a counter inhibiting the read from an address (f) of a rearrangement counter 14. The rearrangement counter 14 has a bit number able to count a parallel number (n) and counts the stuff designation signal (e) outputted from the phase comparator 11 and outputs the address (f) designating a stuff insertion line. A bit replacement circuit 9 rearranges the n-parallel data disturbed by the stuff insertion according to the address (f) outputted by a rearrangement counter and outputs a normal n-parallel data (h). Thus, the parallel stuff insertion operated at a low speed is attained and the power consumption is reduced.

Abstract: PURPOSE:To form a uniform printing film all over an image area, by a method wherein a pressure buffer portion is provided at the lower portion of a printing-direction leading edge of the image area of a relief plate and, thereby, a printing pressure acting between a plate and a medium to be printed is uniformized all over the image area of the flexographic printing plate. CONSTITUTION:A relief plate 12 is composed of a flexible photosensitive resin and thereon cotouts 17 having triangular cross sections are provided from the rear of the relief plate 12 at the lower portions of a leading edge 15 and a trailing edge 16 of an image area 14 to a printing direction shown by an arrow 13 to serve as pressure buffer bodies. When an excessive force acts to the leading edge 15 and the trailing edge 16 of the image area, the cutouts 17 serve as easily deforming buffer bodies so as to make the printing pressure at the leading edge 15 and the trailing edge 16 almost equal to that at the center of the image area. Moreover, a plate thickness h1 of a non-image area 19 abutting against side edges 18 of the image area 14 is made larger than a plate thickness h2 of a non-image area 20 abutting against the leading edge 15 and the trailing edge 16 ; which makes the side edges 18 hard to deform in a vertical direction with respect to the side edges while the leading edge 15 and the trailing edge 16 are made easy to deform in a printing direction. In this manner, a printing pressure is uniformized at the edges of the image area 14.

Abstract: PURPOSE: To enable use of a pulse duration controller for a current inverter even in low rotating speed range by providing means for varying a basic triangular wave with respect to modulated triangular wave.  
     CONSTITUTION: A modulation signal generator 182 receives a basic triangular wave S 1  and produces a frequency signal S 2 .

A comparator 188 compares the modulated triangular wave with the basic triangular wave in magnitude to produce a modulated pulse signal S 4 . Accordingly, when the signal S 2  is raised in proportion to the S 1  during the foreward period of the basic triangular wave S 1 , retained during the intermediate period, and decreased during the latter period as the S 1  is increased from constant value, and the pulse frequency is lowered in the phase instruction range receiving the limit in the current pulse duration and is retained constantly in the range not limited in the pulse duration to retain predetermined vector position, this current inverter may be sufficiently used even in low rotating speed range.
