Title: Control of simultaneous type bobbin changer of spinning machinery and controller
Inventor: NIIMI KIWAMU
IPC: D01H9/04
Filed: 1995-08-01
Abstract: PROBLEM TO BE SOLVED: To make the time required to complete bobbin change operations comparable to that without any mistake in pullout of a full bobbin when the mistake in pullout of the full bobbin is present during the operation of a bobbin changer. SOLUTION: Bobbin change operations are performed by lifting, lowering and displacing a doffing bar having each bobbin holding device between a spindle row and a transfer device arranged thereunder. When an unremoved full bobbin is caused on a spindle, a trouble informing means is operated based on a signal sensed with a sensing means for the unremoved bobbin to inform an operator about the occurrence of the trouble and operations without disturbing the bobbin change operations with the full bobbin remaining on the spindle are successively continued with a bobbin changer. When the trouble is eliminated until the doffing bar starts operations to fit an empty bobbin onto a spindle, the bobbin change operations are continued. When the trouble is not eliminated, the bobbin change operations are discontinued in a state thereof before starting the operations to fit the empty bobbin onto the spindle. After eliminating the trouble, the bobbin chafe operations are then continued.

Filed: 1996-07-09
Abstract: PROBLEM TO BE SOLVED: To prevent destruction of a large quantity of recording data by predicting a life of the magnetic disk device based on a detecting result of an oscillation signal excited in a head due to a magnetostriction effect of the head. SOLUTION: As the prestage of the occurrence of crush between the magnetic head 13 and the disk 11 to cause the destruction of the recording data of the magnetic disk device 10, oxidization of the surface of the disk 11 and foreign matter stuck on the surface, and also foreign matter stuck to a head slider 14 are mentioned to make floating posture unstable. These things incur an opportunity of making the head slider 14 equipped with the magnetic head collide with projections of oxide and foreign matter, etc., of the surface of the disk 11.  Now, in this case, by detecting the occurrence of an oscillation signal output owing to the magnetostriction effect at the collision of the electromagnetic induction type magnetic head 13 against the projections on the surface of the magnetic disk 11, prediction of ending the life can be executed in its early stages, based on the occurrence of the aforesaid crush of the magnetic disk device 10.

Outputs of the phases A and B are inputted into a counter pulse generation circuit 2 as IC, which performs such as differentiation or the like receiving a clock CL from an oscillator 3 to output counter pulses I and J. The pulse I is outputted at the normal operation of the encoder 1 while the pulse J at the reverse operation thereof. The inverted output J is inputted into an adder 5 together with a CW signal I for addition and the output K is sent out to a receiving circuit through a single output signal line 6. Thus, the output signal line can be set in a single to halve the total number of output signal lines thereby simplifying the construction and electric wiring significantly.

Abstract: PROBLEM TO BE SOLVED: To detect with excellent sensitivity coil damage that exists in close proximity and apart from a core, by impressing surge voltage on sample winding in the state of the laminate core having been floated electrically, avoiding corona electric discharge. SOLUTION: A laminate core 1a of a sample motor 1 is provided in the state of having been floated electrically. A degree of depressurization in a depressurization tank 2 is managed by means of a vacuum meter 3, and depressurization is carried out by means of a vacuum pump 5 through a valve 4.

By impressing the surge voltage, electric discharge stress is drastically reduced, and instant peak impression voltage is increased, so detection sensitivity can be improved.  Also, on account of having been floated electrically, surge stress between coils is concentrated, and an optimum depressurization value is sought, so corona electric discharge is avoided, and coil damage in winding is detected with excellent sensitivity.

Title: Device for combustion
Inventor: WAKATA TAKESHI
IPC: F23L3/00
Filed: 1992-06-30
Abstract: PURPOSE:To improve the efficiency at the time of turned-down combustion by making a movable damper vary the ratio in which air is distributed to a main flame part and an auxiliary flame part according as the use of the capacity is high or low and in a manner of making the ratio of the distribution of air appropriate in the full range from the high use to the low use of the capacity. CONSTITUTION:When the use of the capacity is high, a current of air sent from a fan flows at a high velocity so that a movable damper 11 holds a full-open position, causing the flow of air to an auxiliary flame part through an air passageway 9 to have an increased proportion and that of air to a main flame part to have a decreased proportion and the ratio of the distribution of air to be appropriate for the large combustion rate. When the use of the capacity is low, the movable damper 11 closes the air duct under its own weight; then the movable damper 11 and the air duct 10 leave a gap which causes the flow of air to the auxiliary flame part to have a decreased proportion and that of air to the main flame part to have an increased proportion and makes the ratio of the distribution of air appropriate for the small combustion rate. This method enables automatically keeping the ratio in which air is distributed to the main flame part and the auxiliary flame part appropriate in the full range from the high use to the low use of the capacity and hence widening the range in which the combustion is stabilized.
