Title: Yarn detecting device of bobbin
Inventor: FUKUDA TSUTOMU
IPC: B65H63/00
Filed: 1995-03-29
Abstract: PURPOSE: To reduce the labor to detect the presence/absence of the yarn, and to surely detect the yarn by obtaining the output according to the presence/ absence of the yarn through the presence/absence of the passage through a contact member in contact with the spool surface of a bobbin. CONSTITUTION: In starting the knitting, a pattern rod 20 is loaded on a supporting part 21. A contact member 32 is brought into contact with the yarn surface on the pattern rod 20. In this condition, the power supply P and a control device C are in the operating condition, and a knitting machine is turned on. Because the wire 31 is supported in the insulated condition relative to a column 11, no current flows in the wire 31 from the power source P in this stage. As the knitting machine is operated, the yarn on the throstle spinning is reduced in volume, and when the yarn on any pattern rod runs out,the contact member 32 is brought into contact with a body part 22 of the pattern rod 20. The contact member 32 is conducted to the earth through the body part 22, the shaft 21, a ring 23 and the supporting part 12, and the current flows from the power supply P.  A switching means of the control device C is operated by the current, and an abnormal condition is displayed on a display device and an alarm lamp.

Title: Crane
Inventor: KATADA TAKESHI
IPC: B66C13/16
Filed: 1999-03-17
Abstract: PROBLEM TO BE SOLVED: To obtain maximum capacity based on a working mode by adjusting the critical capacity of a crane on the basis of changeover between boom hoisting and luffing modes. SOLUTION: A selected working mode is discriminated, and in the case of a boom hoisting mode being selected (S201), after emergency processing (S202), an adjustment to the critical value of the boom hoisting mode is made on the basis of data on the critical capacity value (S203). The emergency processing means the danger avoiding processing in the case of working in the state of exceeding the critical capacity of the boom hoisting mode when changing over to the boom hoisting mode from a luffing mode. In the case of the boom hoisting mode not being selected as the working mode, whether the luffing mode is selected or not is discriminated (S204). In the case of the luffing mode being selected, the state of a boom hoisting action detection signal is discriminated (S205).  In the case of not OFF, after emergency processing (S202), an adjustment to the critical capacity of the boom hoisting mode is made. In the case of OFF, an adjustment to the critical capacity of the luffing mode is safely made (S206).

Abstract: PURPOSE:To obtain a silent image forming device using a noiseless drive unit by forming tooth forms different in pitch width and the number of teeth at both faces of a timing belt, thereby reducing tooth contact noise at the time of driving. CONSTITUTION:A first and a second tension gears 13, 14 to be interlocked with a timing belt 21 are rotated in the S direction, and a first and a second timing gears 16, 17 are rotated in the (t) direction.

Title: Power supply for laser machining
Inventor: KOIZUMI TOSHIRO
IPC: H01S3/097
Filed: 1998-03-20
Abstract: PROBLEM TO BE SOLVED: To ensure highly accurate machining by setting the frequency of high frequency power being generated from a high frequency power generating means higher than the time constant at the rising time of a laser discharging means. SOLUTION: Since the rate of high frequency power output time increases as the difference between a detection signal and an output command signal Pref increases, laser light W rises sufficiently to produce a high output. The detection is fed back and the difference is detected and then high frequency power is turned on/off to match the laser light W output with a level being set at an output setting section 122. When the frequency of high frequency power being generated from an inverter section (high frequency power generating means) 20 is set higher than the rising time constant at a laser discharging means 110, control speed of the laser light W output can be lowered resulting in fine laser machining.

Title: Complementary insulation gate type logic circuit

Filed: 1986-03-31
Abstract: PURPOSE:To improve the noise margin in the circuit operation against the fluctuation of a power voltage by providing a correction transistor (TR) suppressing the change in the logic threshold voltage lower against the fluctuation of power voltage. CONSTITUTION:If the drop of a voltage VDD takes place, the absolute value ¦VGS¦ of a gate-source voltage of a P-channel TR P1 is lowered and its drive capability is lowered. In this case, since a gate input voltage VDD of a correction TR N2 is lowered, the entire drive capability of the N-channel TR is lowered and in selecting the reduction in the P-channel/ N-channel sides nearly the same, the change in the logic threshold voltage is decreased. In order to make the reduction in the drive capability the same, it is attained by adjusting the W/L of the N-channel TR N2.
