Title: Abnormality detecting device for cutting tool
Inventor: KODAIRA AKIO
IPC: G01M99/00
Filed: 1979-11-20
Abstract: PURPOSE: To reduce erronous signal by a method wherein a signal of 1Hz or less of an acoustic emission (AE) during a cutting work is picked up, and a reference signal which is obtained by adding a proper bias signal to the aforementioned signal is compared with an envelope detection of the AE signal, and if it exceeds a reference signal, an abnormality information signal is sent out.  
     CONSTITUTION: The acoustic emission (AE) during cutting work is detected  through an AE sensor 1, passes through an amplifier 2, an absolute value amplifier  3 and enters an LPF4 having a cut off of for example, 1Hz. And it is output from  the LPF4 as a signal B indicating a break state of a chip and is entered into an  adder 5 wherein a proper bias D is added to become a comparison reference signal  E, then, this signal enters a comparator 7. Whereas, an AE signal output from an  absolute value amplifier 3 passes through an LPF having a cut off of 1kHz, becomes an envelope detection signal C of the AE signal, enters the comparator 7 to  be compared with the reference signal E. And if the compared result exceeds an E,  an abnormality information signal F is output. With this, erronous signals can be  reduced.

Title: Porous heat transfer surface
Inventor: NAKAJIMA TADAKATSU
IPC: F28F1/10
Filed: 1981-09-25
Abstract: PURPOSE:To enable the surface of a porous layer to have a high heat transfer capacity by a method wherein a number of grooves capable of varying regularly the rate of distribution of gaps in the surface of the porous layer are provided  in a part of the surface. CONSTITUTION:The porous layer is formed of a sintered particle layer 11 consisting of sintered particles 10 and the groove 12 are formed in the surface of the porous layer by pressing a knurling tool against the surface. As a result, large open holes 13 which act as active open holes, that is, air bubble developing holes, and small open holes which act as inactive open holes, that is, liquid adsorptive holes, are provided regularly in the heat transfer surface of the porous layer in a certain ratio so that the development of air bubbles and the adsorption of the liquid are stabilized and the boiling heat transfer efficiency of the heat transfer surface of the porous layer is improved. As regards the method of forming the grooves 12 in the surface of the porous layer, it is also possible to form the grooves by cutting in the surface with a bite or a metal saw instead of using the knurling tool such that the small open holes 14 are formed due to the stress generating with the cutting operation.

Title: Control system for dynamic address conversion mechanism
Inventor: IKE ATSUSHI
IPC: G06F12/08
Filed: 1990-06-08
Abstract: PURPOSE:To calculate a real address at high speed by selecting and giving a virtual address inputted to a dynamic address conversion mechanism from a holding means and continuously inputting the virtual address being the object of a processing to the dynamic address conversion mechanism. CONSTITUTION:When the retrieval processing of association storage mechanisms 30a and 30b is failed in an instruction and an operand, two virtual addresses are processed in such a way that they are continuously inputted to the dynamic address conversion mechanism 31 by selecting and inputting the virtual address inputted to the dynamic address conversion mechanism 31 from the holding means 32a and 32b. Consequently, the real address is calculated and it is registered in the association storage mechanisms 30a and 30b even if the use of the dynamic address conversion mechanism 31 is contended. Thus, the real address is calculated at high speed.

Title: Thermal power switching device
Inventor: KASAI ISAO
IPC: F23N1/08
Filed: 1988-06-17
Abstract: PURPOSE:To make igniting sound upon igniting a main combustion part smaller by a method wherein a temperature information from a temperature sensor for detecting the temperature condition of a heating apparatus is inputted to control the opening of a main flame port solenoid valve. CONSTITUTION:A thermocouple 9 detects the ignition of a pilot flame and the thermal electromotive force of the thermocouple 9 is transmitted to a control unit 3 while a control signal is transmitted to a first solenoid valve from the control unit 3 so as to maintain the opening operation of the first solenoid valve 6. When the control unit 3 judges that a temperature in a chamber is lower than a set temperature, the fuel passage of a second solenoid valve 7 is opened to send fuel gas to a main burner 2 whereby the main burner 2 is ignited by the shifting of fire from the pilot flame of a pilot flame burner 8. When the temperature in the chamber has become higher than the set temperature, the fuel passage of the second solenoid valve 7 is closed and the combustion of the main burner 2 is stopped whereby the temperature in the chamber approaches to the set temperature. The opening or closing of the passage of the solenoid valve 7 and the automatic ignition or automatic shut down of the main burner 2 are effected based on a condition whether the temperature in the chamber, which is detected by a temperature sensor 4, is lower or higher as compared with the set temperature.

Title: Burner apparatus
Inventor: NISHIKAWA MAKOTO
IPC: F23N1/00
Filed: 1981-09-22
Abstract: PURPOSE:To obtain a burner apparatus with a simple structure whose heat output can be substantially varied with the stabilized burning state, by providing a vertically movable member. CONSTITUTION:The fuel flowed into a gas chamber 1 from a fuel inlet 2 attached to an upper part of the gas chamber fills the gas chamber 1, flows into discharge pipes 4 into which valve bodies are pushed up and is discharged from the fuel discharge outlets 7. As the lengths of pushing rods 9 are different, according to the vertical position of a float 8, the number of passages that communicate the gas chamber 1 and the discharge pipes 4 can be varied. That is,  when a large quantity of fuel is required to be flowed, a liquid 10 in a large quantity is fed in the gas chamber 1 to elevate the float 8 so that a large number of the discharge pipes 4 are communicated with the gas chamber 1. In case  a small quantity of fuel is to be flowed, the liquid 10 is withdrawn from the gas  chamber 1. Then the float 8 is lowered, and a small number of discharge pipes  4 are communicated with the gas chamber 1. Accordingly, with the stabilization  of the burning state, the heat output can be substantially changed, and therefore  a burner with a simple structure can be obtained.
