Title: Resin pipe
Inventor: FURUKAWA NORIHIRO
IPC: F16L11/12
Filed: 1998-07-24
Abstract: PROBLEM TO BE SOLVED: To print an insertion length beforehand, and facilitate an appearance of its print by distributing colors whose hues are different from each other in its surface at nearly equal clearances and at least in a longitudinal direction, and setting a boundary of the hues perpendicular to the longitudinal direction. SOLUTION: An insertion amount W of a resin pipe 21 is a depth until the step part 2 of a joint 1, and it is incomplete that a claw 9 of a holding ring 5 is engaged with the resin pipe 21 in the case where it not exceed the insertion amount W. Colors A, B, C... are distributed individually at a width W in the longitudinal direction, and the resin pipe 21 can be cut every line whose colors are distributed. A worker confirms that the resin pipe 21 is completely connected to the joint 1 by inserting the resin pipe 21 into the joint 1 until the color of a tip end disappears. Thus the insertion is not short, and it is also possible to prevent generation of leakage of water.

Abstract: PURPOSE:To enable a movable table to be fastly fed and slowly fed, by making the pitch feed and the direction of screw different between a nut on the side of the movable table and a nut on the side of a bed, both nuts being threadedly engaged to one ball-and-screw shaft. CONSTITUTION:When a ball-and-screw shaft 10 rotates, the ball-and-shaft 10 advances by being guided by a support bearing 18 attached to a bed 19, and simultaneously, a movable table 20 advances at a fast feed with respect to the bed 19 in the same direction as that of the advance of the ball-and-screw shaft 10, since a left-handed screw 13 is threadedly engaged to a support bearing 18 secured to the movable table 20. Further, a ball-and-screw unit of slow feed type may be easily manufactured by forming screws having different pitches in the same direction on ball screws 12. 13.

Title: Machine controller
Inventor: SUZUKI TAKAHIRO
Filed: 1985-09-25
Abstract: PURPOSE:To simplify the overall system constitution by providing a system control part to control the control units of each machine system. CONSTITUTION:When a control command is given to a controller 11, the command is received by a system control part 12 and allocated to control units 13, 15 and 17 respectively. These units receive a specific control command from the part 12 to attain a fixed action of a machine system. Thus the units 13-17 control the machine systems 14, 16 and 18 respectively. While the part 12 control these units 13-17 independently or integratedly by the control command and therefore can given the simultaneous or coupled flexible control as a whole to >=2 machine systems. Thus the overall system constitution can be simplified for a machine controller together with the reduction of cost.

Filed: 1985-09-25
Abstract: PURPOSE:To reproduce a picture with high quality in conventional television system and in high definition television system compatible with the former by constituting the titled receiver so that dynamic information is detected from a received signal, a luminance signal, chrominance signal, and a high frequency luminance signal are separated, and demodulated three primary color signals are displayed in form of sequential scanning for sixty frames. CONSTITUTION:A video signal of base band is separated into a luminance signal low frequency component YL, a chrominance signal C, and a high-definition signal Y'H by a separating circuit through an A/D converter. In this case, the presence or absence of dynamic information is detected by a detecting circuit, and the separation processing is executed in conforming to the dinamics. A signal Y'R is demodulated to the original luminance signal high frequency component YH by a de-modulation circuit, and is added to the delayed signal Y to make a wide band luminance signal Y. Meanwhile, the chrominance signal C is demodulated to a color difference signals I and Q by a demodulation circuit. The scanning lines lacking in the field of said signals I and Q are interpolated by an interpolation circuit with interlace scanning of conventional television system, and the signal is converted to R, G, B and RIP, GIP, and BIP signals. After the convertion by a time base conversion circuit, the signals are converted to analog signals R;, G', and B' by a D/A converter, which are displayed by sequential scanning for a share of sixty frames.

Title: Planetary gear unit
Inventor: KAJIWARA HIROSHI
IPC: F16H1/28
Filed: 1984-10-05
Abstract: PURPOSE:To improve the constitutional strength of a planetary gear unit by engaging a supporting column which engages primary and secondary carrier plate with each other with the external form of a rotary part so as to increase the joining strength of both the primary and the secondary carrier plate. CONSTITUTION:The external form of a supporting column 28 at the rotary part of a carrier plate is engaged with the side wall 31a of a recess part 31 so that a force will be transmitted to the side wall 31a via the external form part of the supporting column 31. Since the force will not be concentrated to a stage part 29 and the rigidity of the primary and the secondary carrier plate 26 and 27 can be made higher. Since the base part of the stage part 29 that has the poorest strength is placed in the lowest position of the supporting column 28, a intense bending moment will not be produced at the stage part 29 so that the gear unit obtains sufficient strength.

Abstract: PURPOSE:To realize fine heat-cooking and enhance safety against damages by a method wherein an output from either one of a first or a second amplifier circuit is set as reference and, when an output from the other amplifier circuit does not coincide with a stored value, it is judged that damages occur, thereupon a control means stops the operation of a heating means. CONSTITUTION:According to an output from an amplifier buffer circuit 9, a microcomputer 21 controls a temperature in an oven case so as to permit cooking in the oven. When food is cooked in the oven at a temperature of, for example, 200 deg.C, the microcomputer controls an upper heater 4 and a lower heater 5 so that the input to an A/D converter 22 is 2.9V. When the control is done at a low temperature; in the case where an input voltage to an A/D converter input 24 is XV, it is judged that there is abnormality, unless the input voltage V1 to the A/D converter input 24 has a value in which X is substituted to V1=f(X)+ or -0.1(V). For example, in the case where the input voltage to the A/D converter 22 is 2.9V, a function 'f' is f(2.9)=1.5V; therefore, it is judged that abnormality occurs, unless the inputted voltage to the A/D converter input 24 is within the range of 1.5+ or -0.1V. Thereupon, the feeding of electric power to the upper heater 4 and the lower heater 5 is stopped.
