Title: Method for winding frp steering wheel core
Inventor: TERADA MAKI
IPC: B62D1/04
Filed: 1987-01-20
Abstract: PURPOSE:To obtain a two- or four-spoked steering wheel excellent in product form and fatigue strength by a method wherein a boss part and spoke parts are formed by hooking a fiber to pins on some time and not by hooking the fiber to the pins on another time. CONSTITUTION:The winding patterns of a FRP steering wheel core consists of patterns A1, A2-C1, C2. In case of the pattern A1, a ring part is formed not by hooking a long resin-impregnated fiber to the pins 4 of a winding jib. On the other hand, in case of the pattern A2, the ring part is formed by hooking the long resin-impregnated fiber to the pins. Next, in case of the pattern B1 or C1, the ring part, two or four spoke parts and a boss part are formed not by hooking the long resin-impregnated fiber to the pins. On the other hand, in case of the pattern B2 or C2, the ring part, the two or four spoke parts and the boss part are formed by hooking the long resin-impregnated fiber to the pins. By employing the patterns A1, A2, B1 and B2 or the patterns A1, A2, C1 and C2 in such a manner that the respective winding patterns are performed alternately or dispersedly, fibers intertwine with one another as braided at branch parts, resulting in allowing to obtain an aimed-at FRP steering wheel core.

Abstract: PURPOSE:To improve the abrasion resistance by forming a chromium layer at least either at a hammer pin or at a pin hole part of a printing hammer which slides in friction with the hammer pin, and forming a setting layer of a solid solution of nitrogen or carbon and chromium or of a compound of nitrogen or carbon and chromium. CONSTITUTION:A chromium layer is formed at least either at a hammer pin 3 holding a printing hammer 4 or at a pin hole part 2 of the printing hammer 4. The pin hole part 2 slides in friction with the hammer pin 3. At the same time, a setting layer is formed of a solid solution or compound of nitrogen and chromium. The setting layer is preferable to have 1,600 or more Vickers hardness and 3mum or more thickness. Any thickness and hardness of the layer can be selected as desired according to the forming conditions. In the case of sputtering, the film becomes uniform because of the utilization of the glow discharge in plasma. The film becomes harder when the containing amount of nitrogen or carbon in chromium is increased. The quantity of gas in the ambience and the film forming conditions are adjusted in order to obtain a desired hardness of the film. In this manner, the abrasion resistance is enhanced.

Filed: 1988-01-21
Abstract: PURPOSE:To form an image more approaching the original image from less sampling data by obtaining an estimated image of ringing, generated by the interpolation spreading method, and performing a ringing correction subtracting the estimated image of ringing from an image obtained by the interpolation spreading method. CONSTITUTION:Ringing, generated by discontinuing a high frequency component of a magnetic resonance signal by interpolation spreading, is estimated being based on a high frequency component, generated by applying a smoothing process holding an edge in an interpolation spread image, and ratio of an image, subtracting the smoothing process-applied image from a stored spread image, to the estimated ringing is obtained. In case of the ratio being out of the predetermined limited range, the ringing is corrected so as to obtain the ratio within the range, and the ringing is smoothed obtaining its correction coefficient. Multiplying the estimated ringing by the correction coefficient to be corrected, by subtracting an estimated image of corrected ringing from the interpolation spread image, a corrected magnetic resonance image of almost no ringing is obtained.

Title: Television tuner circuit
Inventor: IWASE AKIO
IPC: H04N5/44
Filed: 1981-01-28
Abstract: PURPOSE:To realize the remarkable improvement of an input/output characteristic at UHF, by providing a power supply switching circuit between a collector load resistor of a differential amplifier of a local oscillation circuit and a power supply. CONSTITUTION:At VHF reception, a voltage obtained from a Bv via a power supply block A is applied to a base of a transistor (TR)1 to conduct it and a differential amplifier of a local oscillation circuit consisting of TRs10, 11 is operated. On the other hand, at UHF reception, since no power supply Bv is applied, the TR1 is nonconductive. Thus, the collector voltage of the differential amplifier consisting of the TRs 10, 11 is lowered to a voltage divided with resistors R5, R6 and since a diode between the collector and base of mixer TRs 4, 5, 6, 7 is sufficiently in reverse bias, no leakage of a signal from the collector to the base is caused. Thus, the input and output characteristics of the amplifying circuit consisting of TRs 12, 13, 14, 15 for UIF can remarkably be improved.

Abstract: PURPOSE:To blow off a piercing pin in a fixed direction and make a hole at a specified position on a ceramic green sheet by supporting the piercing pin by two plate springs arranged parallel to each other. CONSTITUTION:A piercing pin 7 is supported by two plate springs 5, 6 arranged parallel to each other. Thus, even when the piercing pin 7 is blown off by elongating force of a piezo-electric device 2, its blowing direction is constantly fixed.

Like this, a hole can be exactly pierced at a specified position on the ceramic green sheet 10, and thus the yield of a ceramic multilayer wiring board can be improved.
