Filed: 1985-07-10
Abstract: PURPOSE:To conduct control by detecting currents for a power converter precisely by adding a detecting current integrating circuit and a switching circuit clearing the integrating value of the detecting current integrating circuit while synchronizing with the operating frequency of an inverter section to a current detecting circuit. CONSTITUTION:DC voltage from input terminals 1, 2 is lead out of output terminals 5, 6 through an inverter section 3 and a rectifying smoothing circuit 4. A current detecting circuit 9 detects the input currents of the inverter section 3, and transmits an output from the inverter section 3 over a control section 8 through a comparator 11. The control section 8 drives the inverter section 3 through a driving circuit 10. In the current detecting circuit 9, a resistor 9C and a capacitor 9D constitute a detecting current integrating circuit, and a switch 9E also functioning as a transistor synchronizes the integrating value of the capacitor 9D with the operating frequency of the inverter section 3 and clears it.

Title: Digital frequency meter
Inventor: YANAIDA YOUICHI
IPC: G01R23/10
Filed: 1982-08-31
Abstract: PURPOSE:To obtain a digital frequency meter having rapid dummy responsiveness, by controlling whether a display value is renewed or not corresponding to the newest calculation value among a pulse calculation values corresponding to frequency and the display value. CONSTITUTION:A calculation value corresponding to the frequency from a pulse counter 2 is applied through an operation circuit 3 and a latch circuit 4 and digital frequency is displayed by a display device 5. This circuit 3 is controlled through a comparator 6 for deciding whether the difference of the newest calculation value from the counter 2 and the past display value through the circuit 4 is equal to and more than a definite range or not. When said difference is equal to and more than said range, +1 is added to the calculation value of the counter 2 in the circuit 3 to renew the display of the display device 5 and display is successively renewed until frequency becomes stable to constitute a digital frequency meter rapid in dummy responsiveness. In addition, even if display renewal is controlled by the range of display change difference through registers 7-9, a similar result is obtained.

IPC: B29L31/10
Filed: 1995-06-20
Abstract: PURPOSE: To easily fabricate a handrail member equipped with skid prevention by enclosing the outer surface of the handrail member with a synthetic resin having an uneven thickness part by means of an extrusion process, and forming a surface unevenness on the uneven thickness part immediately after extrusion continuously using a shaping roll. CONSTITUTION: A long core 1 consisting of a pipe of aluminum, stainless steel, or FRP pipe is enclosed seamlessly with a synthetic resin layer 2 consisting of an uneven thickness layer 3 having a large thickness and a uniform layer having a small thickness. The enclosure is formed by passing the core 1 through a cross-head extruder and extruding the synthetic resin 2 from the periphery in such an arrangement that the over-part is made thinner and the under-part thicker. Immediately after extrusion, recesses 4 and projections 5 are formed in the uneven thickness layer 3 located under continuously using a shaping roll 7. If necessary, wood chips are mixed with the synthetic resin 2 to give the handrail a high grade sense of wooden tone. When a person grips the handrail, his fingers are engaged by the surface unevenness of the handrail to preclude risk of slip.  Thus a handrail equipped with slip prevention can be fabricated easily and at a low cost.
