Title: Cartridge type tape recorder
Inventor: FURUSAWA TOSHIAKI
IPC: G11B15/48
Filed: 1984-06-28
Abstract: PURPOSE:To ensure a smooth and stable stopping operation of a tape from a quick traversing mode by turning off the 2nd switching circuit by a time constant circuit with a delay of a fixed time in a stop operation mode and driving a motor at a low speed via a current limiting resistance. CONSTITUTION:When a quick traverse operation is stopped, the Q output of a flip-flop circuit 7 is set at L level. Thus the 1st switching circuit 9 is turned off and the revolution of a motor 14 is quickly stopped. While the 2nd switching circuit 12 is kept on for a period of time decided by a time constant circuit 13. Meanhile a current limited by a resistance 16 flows to the motor 14, and the motor keeps its revolutions at a low speed for a fixed period of time and is stopped. Therefore the tape driving is not stopped suddenly but stopped after driving at a low speed for a little while. Thus the tape is never drawn between a reel and a tape guide.

Title: Tig welding method
Inventor: MITA TSUNEO
IPC: B23K9/167
Filed: 1989-05-30
Abstract: PURPOSE:To obtain an uniform weld bead by setting the arc length in the region where the arc length is longer than the region where the arc length is in proportion to the depth of penetration and the depth of penetration is not changed by the arc length. CONSTITUTION:Nonconsumable electrode arc welding is performed by using a welding power source having an almost constant-current characteristic. The arc length is then set in the second region where the arc length is longer than the first region where the arc length is approximately in inverse proportion to the depth of penetration and the depth of penetration is hardly changed by the arc length. In addition, the arc length is set in the third region where the arc length is longer than the second region and the depth of penetration is approximately in proportion to the arc length. By this method, a drop of a welding current due to resistance heat generation of an electrode is suppressed and fine welding is performed.

IPC: H02M3/335
Filed: 1982-08-02
Abstract: PURPOSE:To prevent transistors from generation of the short-circuit phenomenon by a method wherein th primary winding of a transformer is constructed of two windings, and the transistors to generate the short-circuit mode are connected to different windings respectively. CONSTITUTION:When ON signals are transmitted to the bases of the transistors 2, 5 from a driver circuit 13, a voltage is induced in the secondary winding of the transformer 10, and a DC current rectified and smoothed by a rectifying and smoothing circuit 11 is applied to load 12.

Title: Electric discharge machine
Inventor: ITOU TETSUROU
IPC: B23H1/02
Filed: 1982-08-02
Abstract: PURPOSE:To prevent generation of abnormal arc discharge by discriminating the working state from the distribution of the frequency components in the wave-form signal of the electric discharge which is generated in a working gap and controlling the length of the gap. CONSTITUTION:The frequency spectrum of the pulse-voltage wave form of the electric discharge pulse generated in a working gap during electric discharge work is different in each electric discharge state. Normal electric discharge and abnormal arc discharge are discriminated from each other according to the existence of the frequency constituent at a fairly higher frequency fH than the fundamental frequency f0 of the electric discharge pulse. Normal or abnormal working state is discriminated from the frequency of generation and the number of successive generation etc. of abnormal arc discharge, and a driving apparatus for electrode feeding is controlled according to the values described in the above, and the length of the gap is varied so as to maintain the normal working state.

Title: Method for preventing decarburization of inside surface of steel tube
Inventor: TANIMOTO SEIJI
IPC: C21D9/08
Filed: 1989-05-29
Abstract: PURPOSE:To almost perfectly prevent the decarburization of the inside surface of a steel tube, in the stage of subjecting the steel tube to heat treatment in a decarburizing atmospheric furnace, by coating the inner surface of the steel tube with a mixture of graphite and a liquid hard to burn at a high temp. before executing heat treatment. CONSTITUTION:In the stage of subjecting a steel tube to heat treatment in a decarburizing atmospheric furnace (such as a direct fire heating-type annealing furnace), the inner surface of the steel tube is coated with a mixture of graphite and a liquid hard to burn at a high temp. (heavy oil is preferable) before executing heat treatment. Furthermore, the mixing ratio of the graphite to the liquid is not particularly limited and the film thickness is not particularly limited if only the inner surface of the steel tube is coated without gaps. In this way, the decarburization of the inner surface of the tube caused by heat treatment in a decarburizing atmospheric furnace can sufficiently be prevented to unnecessiate the grinding removal of a decarburized layer after subjected to heat treatment, by which the steel tube for machine structural use of a bearing steel tube can advantageously be manufactured.

In a comparator 14, the counted value of the counter 12 and the first preset value are compared, and the fact that the specified correlation is achieved is detected. An FF 15 is set and reset with the output signals from the comparator 14. The second preset value is preset in the counter as an initial value in response to the output signal of the FF 15. The detecting level is set with the first preset value. The width of hysteresis is set with the second preset value. Thus, the accurate detection of the state of loading can be performed.
