Abstract: PURPOSE:To save an ink film by decelerating the conveying speed of the film or to raise a printing density by accelerating the conveying speed by generating a predetermined relative speed between the conveying of the film and the moving of an ink transferring mechanism to print it. CONSTITUTION:Driving circuits 205, 206 for a carriage motor 204 and a film motor 115 respectively control the rotating direction and speed of the motors 204, 115 on the basis of a digital input signal. That is, the rotating direction of the motor 204 is controlled by a rotating direction control signal SD from a printing mode controller 501, and the rotating speeds of the motors are controlled by the frequencies of the signals SPA, SPB frequency-divided by frequency dividers 507, 508 from a continuous SP pulse signal by generating the continuous pulse SP signal by controlling a pulse generator 502 by the controller 501. Thus, the using amount of an ink film can be saved to half, and the printing density can be enhanced twice, three or four times as required.

Title: Method for testing magnetic disk medium
Inventor: OKADA YASUE
IPC: G01N19/08
Filed: 1984-12-25
Abstract: PURPOSE:To accurately test the surface flaw of a magnetic disc medium at every condition, by detecting an AE signal on a slice level corresponding to each condition. CONSTITUTION:At first, as a magnetic disc medium 3, a master magnetic disc medium is attached to a spindle 10 and a motor M is rotated. Then, a magnetic head 13 for detecting a projection is moved by a carriage 11 and the detection of the projection is performed by the outer periphery of the disc medium 3. At this time, a slice level is gradually lowered and the slice level, when the AE signal was detected, is stored in memory 23. Next, the magnetic disc medium is replaced with a magnetic disc medium to be tested. Slice level setting data is read from the memory 23 to be inputted to a comparator 17 which, in turn, compares this slice level with the detection output of the AE detection element 14 of the disc to be tested. As a result, an error signal is outputted when the AE signal larger than the slice level is detected.

Filed: 1987-11-07
Abstract: PURPOSE:To measure the amount of applied electrostatic energy, by forming a plurality of other conductivity type diffusion resistances which are deteriorated for the first time by applications of electrostatic energy different in its amount and next by measuring the respective diffusion resistances at the prescribed points of time. CONSTITUTION:A ratio W/L of a width W of P<-> layer 2 to a length L between electrodes 5 is kept constant and the lengths are varied 10, 20, 30, 40, 50, 60mum to form diffusion resistances 21-26. Even in the case of the diffusion resistances 21-26 with constant resistance values, a proportional relation is generated between the length L of the resistance and the voltage which deteriorates the resistance. When the substrates are carried together and the values of the diffusion resistances 21-26 are measured on appropriate occasions to detect the deteriorated resistances, it can be known how much electrostatic energy is applied until prescribed time. The amount of the applied electrostatic energy can be hence measured.

Abstract: PURPOSE: To make it possible to feed a needle thread by forcibly releasing an operation to provide the thread with tension while a sewing machine is detected making a thread cutting action, and to feed the thread even when a balance is elevated during a thread cutting action to prevent a thread from escaping out from a sewing needle. CONSTITUTION: A needle thread tension sensor 17 is disposed in a thread handling area that reaches to a sewing needle from a thread supply source in a sewing machine to detect tension on the needle thread. A piezoelectric thread holder 16 provides the needle thread with tension as a result of telescoping action of the piezoelectric elements. Furthermore, a needle thread tension adjusting means 74 in a thread balance controlling device 4 adjusts the tension given to the needle thread according to the detected tension on the needle thread. In this case, the thread balance controlling device outputs at least a thread cutting signal that indicates the needle thread being cut from a thread cutting signal generating circuit 70.  The tension providing action by the piezoelectric thread holder 16 is forcibly released by a forced thread releasing means comprising a D flipflop 72 and an AND circuit 73 at least while the thread cutting signal is outputted.

Title: Engine driven chiller
Inventor: KONNO HARUHIKO
IPC: F25B27/00
Filed: 1998-10-05
Abstract: PROBLEM TO BE SOLVED: To regulate capacity control automatically to match actual situation by regulating the maximum r.p.m. of an engine based on the difference between the inlet/outlet temperature of cold and hot water of a refrigerant/water heat exchanger during actual operation and the inlet/outlet temperature during rated operation. SOLUTION: A controller 11 performs capacity control by regulating the maximum r.p.m. Nb of an engine 7 according to a following formula. Nb= K |Cs-T1|×|Ts2-Ts1|/|T2-T1|+|Cs-T2|}+Ns where, K is a rotational coefficient, Cs is a set temperature, Ts1, Ts2 are inlet/outlet temperature of cold and hot water at the time of rated operation, T1, T2 are inlet/outlet temperature of cold and hot water during actual operation, and Ns is lowest r.p.m. When the flow rate of brine flowing into a refrigerant/water heat exchanger unit 2 exceeds a rated flow rate, the controller 11 increases the r.p.m. of the engine 7 based on the outlet temperature difference |Cs-T2|and, at the same time, increases Ns to correct the maximum r.p.m. When the flow is lower than the rated flow rate, Ns decreases to correct the maximum r.p.m.

Abstract: PURPOSE:To provide a facsimile receiving function while reducing the danger of trouble by providing a specific condition setting means which stores setting conditions by a copy condition setting means in response to the output of a recording request signal from a recording control means, and then automatically sets the operation conditions of an image forming means to specific conditions for the recording of recording information and also sets the operation conditions of the image forming means to the stored setting conditions again at the end of the recording operation. CONSTITUTION:When a recording request signal is outputted from the recording control means so as to start recording operation in response to a facsimile call signal, etc., from a telephone line, the specific condition setting means stores the setting conditions by the copy condition setting means temporarily and then automatically sets the operation conditions of the image forming means to, for example, conditions wherein the side of a recording form is 'A4' and black recording is carried out on only one sheet of paper. Even if the facsimile signal is received before an automatic resetting function operates, the conditions do not suit for the facsimile recording, so neither a waste nor the partial absence of information is caused.
