Title: Device for driving multiimpact motor, for stapling
Inventor: CAMINO FRANCISCO JAVIER
IPC: B27F7/36
Filed: 1997-04-03
Abstract: PROBLEM TO BE SOLVED: To make it possible to staple a thick stack of paper sheets with the help of a stapler with an optimal performance for a stack of thin paper sheets by driving a staple into the paper stack under the impact of a pulse generated by applying a specified electric power to a motor and emitting a second current pulse to a thicker paper stack. SOLUTION: A hammer 41 is moved downward by a blank motion lever 37 driven by a motor 31 and a pin 38 and thereby, a staple is driven into a stack of paper sheets 47 and then is folded by the glove of a collet 51. Next, electric current of the adequate level to staple a stack of thin paper sheets 47 is supplied. However, when the stapling process is not yet completed because the stack is thick so that the hammer 41 and a cam 57 do not reach an object or their home positions within a normal cycle time, the supply of electric current to the motor 31 is suspended, and the hammer 41 is disengaged with the stack 47, and further, the supply of electric current is resumed after a load on the motor 31 is lessened by the interruption of current supply to the motor 31. In addition, the hammer 41 and the stack 47 are again connected to each other.  Thus it is possible to staple even a thick stack of paper sheets 47.

Abstract: PURPOSE: To make it possible to effect the stopwatch display of 0.01 and 0.1 seconds within an error of 0.001 seconds by using the suitably divided frequency of a crystal oscillating circuit.  
     CONSTITUTION: The frequency of a crystal oscillating circuit 1 is divided to produce signals of 1 Hz so that the time is displayed through counters 3, 4 and 5 in display devices 6, 7 and 8. From midway of the frequency dividing circuit, on the other hand, signals of 4096 Hz are taken out and are divided into 1/41 by a counting circuit 11 to produce display signals of 0.01 seconds and into 1/10 to produce signals of 0.1 seconds. The signals for the stopwatch are displayed through decoders 14 and 15 in display devices 16 and 17. These signals contain an error of 0.001 seconds, but the integrated errors are corrected by a reset gate circuit 23 each time one second is counted so that the stopwatch display of seconds, minutes and hours is performed with the use of the time display devices 6, 7 and 8. Thus, it is possible to effect the stopwatch display up to 0.01 seconds with a slight error.

Abstract: PURPOSE:To enable the use of a total amount of stored hot water without lowering of the temperature of the hot water and to improve the efficiency of a hot water boiler by providing a heat insulating plate by which hot and low temperature water are isolated from each other. CONSTITUTION:A heat insulating plate 9 has a specific gravity of approximate 1, is not permeable to water and is a bad conductor for heat, and is adhered to an inner wall 1' of a hot water storage tank. Assume the thickness of the heat insulating plate 9 is T and the diameter of a water feed pipe 4 is phi, T>phi, and a mounting position interval S between the upper and lower ends of the water supplying pipe 4 is set to a value equal to T. A heat collector 2 is actuated, low temperature water is sucked out with the aid of a pump 3, high temperature water is fed, and the heat insulating plate 9 is moved downward. The insulating plate is finally lowered down to the position of the water feed pipe 4, the heat insulating plate 9 is further lowered, and the lower opening of the water feed pipe 4 is closed approximately completely by means of the heat insulating plate 9. Water is circulated between the heat collector 2 and a hot water storage tank 1, and water above the heat insulating plate 9 is warmed by the heat collector 2. A faucet 8 of a hot water supplying port is opened to supply hot water, cold water of an amount equivalent to that of the supplied hot water is supplied through a water supplying pipe 6 and the heat insulating plate 9 is pushed up. Since water at a high temperature part is isolated from water at a low temperature part by the heat insulating plate 9, the two kinds of water are prevented from mixing together.

Abstract: PURPOSE:To improve stability by dividing the discharge space of a display cell into two sub-cells, and performing a maintenance discharge in turn. CONSTITUTION:Negative voltage is applied to a priming electrode PM for a short time, then it is gradually recovered to the initial potential. Writing pulses of Voltage VW are applied to a writing anode after a preliminary discharge, scanning pulses of VKW are applied to a cathode, and writing is performed for all lines in sequence. Maintenance pulses of VS are applied to maintenance anodes S1A, S2A, the maintenance anodes S1A, S2A are driven in turn, and phases are indicated as phi1, phi2. A maintenance discharge is continued between the maintenance anode and all cathodes completed with writing by the maintenance pulse drive in phases phi1, phi2. The period when the cathode is kept at the voltage VKS after writing becomes the maintenance light emission period, and the intensity obtained by the sub-field can be controlled when the length of this period is controlled. Deletion pulses of voltage VE are applied to the cathode after the period is completed to delete the maintenance discharge. Stability can be improved.
