Title: Method for hardening steel material with beam
Inventor: TSUKAMOTO TAKASHI
IPC: B23K26/352
Filed: 1987-06-16
Abstract: PURPOSE:To stably produce a steel material having a fine uniform surface- hardened structure by making the structure of a steel material uniform by heat treatment before hardening with a beam. CONSTITUTION:Before hardening with a beam, steel material is heated prefer ably at a sufficiently high temp. below the Ac1 transformation point for a suffi ciently long time in a furnace and is rapidly cooled in water. The resulting hardened steel material having a hardened structure is tempered preferably at a sufficiently high temp. below the Ac1 transformation point for a sufficiently long time to form a fine tough sorbite structure. The steel material is then hardened with a high energy beam such as electron beam to form a uniform fine martensite structure. Thus, a uniform hardened layer is stably obtd. up to a sufficiently large depth of the steel material.

Filed: 1985-07-09
Abstract: PURPOSE:To improve the temperature characteristic of a constant electric current by making the temperature characteristic of a resistance inserted between gate sources of an electric field effect transistor into the comparatively large positive value. CONSTITUTION:When between gate sources of the electric field effect transistor, the general resistor whose resistance value is 4.2kOMEGA is inserted and the constant electric current of 75muA is obtained at 0 deg.C, the electric current temperature characteristic of the transistor is 94muA at 100 deg.C, namely, shows the electric current increase of +25.3%. This means that each time 1 deg.C advances, the electric current is changed positively to 2,530 PPM only, and is inconvenient as the constant electric current source. Then, by giving the resistance change between gate sources so that the change can come to be the resistance value of 4.2kOMEGA and the resistance value of 5.61kOMEGA an initial electric current 75muA (0 deg.C) is constantly kept. Thus, the stable constant electric current, which is not influenced by the ambient temperature, can be easily and low-pricedly obtained.

Filed: 1995-06-16
Abstract: PURPOSE: To prevent the deterioration of reproducing efficiency due to arithmetic interpolation by uniformly distributing sample points in an input space so as to allow the error of each sample point to uniformly affect the whole space at the time of preparing table data. CONSTITUTION: An output from an arithmetic interpolation part 1 and that from a black generation part 2 are added to obtain a printer input signal. A printer model 3 is a model obtained by measuring an actual printer. The data pair of an input signal to the arithmetic part 1 and an output signal from the model 3 is sent to an optimizing part 4 to optimize table data. The optimization part 4 obtains table data by arithmetic convergence through the use of a method of attenuating least squares method. Namely, what is obtained first is an error function concerning the square error between the input signal of a system and the output signal from the model 3 obtained by arithmetic interpolation, etc., using LUT 2. Next, simultaneous equations with respect to each grid point concerning the least quarters problem of the error function are solved for each sample point.  Then, when sufficient convergence by an evaluation function is judged, the updated value at the time is set to be the solution.

Filed: 1980-10-29
Abstract: PURPOSE:To enhance the dielectric strength of a switch circuit, by providing a switching element between the output of thes witch circuit, which is connected between a power source and the earth, and a load. CONSTITUTION:When a signal is not applied to a terminal T1, an MOSFET Q1 is turned off, and the voltage between the source and the gate of an MOSFET Q2 is zero approximately, and therefore, the FET Q2 is turned off. However, the junction between the source and the drain of the FET Q2 is forward bias, and a capacitor Cc is charged up to a power source voltage VDD. When a signal is applied to the terminal T1, FETs Q1 and Q2 are turned on, and the potential at a point C jumps up to a maximum 2VDD by storage energy of resonance circuit C0 and L0, but only the voltage VDD at most is applied between drains and sources of FETs Q1 and Q2, thus preventing the breakdown of FETs.

Title: Original carrying device
Inventor: KITAHARA MAKOTO
IPC: H04N1/407
Filed: 1988-06-20
Abstract: PURPOSE:To surely prevent the back copy of a 2-sided original by using a 2-sided original setting means and a density changing means which gives an instruction to a picture processor to change the reference of density for the original reading process or the picture output process based on the input signal of the original setting means. CONSTITUTION:A control part 300 of an original carrying device contains a density changing means 301. The means 301 is programmed so that it outputs a changing instruction to a control part 400 of a copying machine for the reference of density for the original reading process of an original reading part or for the copy process of a copy part based on the input signal sent from a 2-sided original setting button 4. As a result, the back copy can be avoided even with a 2-sided original. That is, both the reading and printing densities of the copying machine are changed to the densities for copy of a 2-sided original when this 2-sided original is once set. Then the density level is lowered so as to avoid the 'back copying'.
