Title: Method for carburizing and nitriding steel member containing chromium
Inventor: MIWA YOSHIHISA
IPC: C21D6/00
Filed: 1985-08-07
Abstract: PURPOSE:To improve the toughness and fatigue strength of a steel member contg. Cr by subjecting the steel member to carburization, reheating to a specified temp. and nitriding so as to prevent the formation of an abnormal structure. CONSTITUTION:A steel member contg. Cr is carburized, reheated to 850-900 deg.C and held at the temp. for a prescribed time. By this heat treatment, the grains are made fine and chromium oxide produced during the reheating is decomposed and allowed to enter into the solid soln. again. The steel member is then cooled and nitrided at 800-850 deg.C. By this method, the formation of an abnormal structure can be prevented and the toughness and fatigue strength of the steel member can be improved.

Title: Semiconductor storage device
Inventor: OGUCHI AKIRA
IPC: G11C11/413
Filed: 1993-07-14
Abstract: PURPOSE:To easily detect a defective memory cell by adding a circuit embodying test function by changing the delay quantity of the delay circuit in a pulse signal synthesizing circuit. CONSTITUTION:In an internal synchronization type semiconductor storage device having an address transition detecting circuit 8 and the pulse signal synthesizing circuit 11, a mode switching circuit 15 controls a circuit 11 so that the pulse width of an address transition detecting signal ATD at the time of a test becomes shorter in comparison with the pulse width of the signal ATD at the time of a normal operation. As a result, the pulse width of a bit line precharge equalization signal BLPCb formed in an internal control circuit 27 based on the signal ATD is shortened. Thus, in the case that the data of a memory cell selected after an address is changed is read-out. a bit line precharge equalization is not performed sufficiently and the data of a marginal memory cell can not be read-out and then the defective memory cell can be easily detected.

Title: Cutting method using ball end mill and miller control device
Inventor: OKURA KAZUTAKA
IPC: B23C5/10
Filed: 1998-06-22
Abstract: PROBLEM TO BE SOLVED: To greatly enhance the accuracy of finished size in cutting a die or the like with a ball end mill by enabling proper tool inclination angles to be set without trial and error through a cutting test. SOLUTION: A miller control device 3 determines, through numerical calculations based on numerical inputs from a CAD/CAM processing device 2 or the like, the proper values of inclination angles βf βp at which bending moments working on a tool are restrained, thus properly setting the tool inclination angles of an NC miller 4. In the numerical calculations, the longitudinal inclination angle βf and horizontal inclination angle βp initialized and estimate values corresponding to the longitudinal and horizontal bending moments applied to the tool are calculated.  Resetting of the inclination angles βf, βp and the estimation are repeated until the estimate values both come to near zero, thus calculating the proper values of βf, βp Since the bending moments working on the tool during cutting are reduced and the tool is not deflected, accuracy is greatly enhanced.

Title: Dc motor control circuit
Inventor: YAGUCHI OSAMU
IPC: H02P7/29
Filed: 1989-07-06
Abstract: PURPOSE:To shut OFF a driving circuit at the time of restriction and to prevent heat generation, electric energy loss of the circuit at the time of restriction by detecting a motor pulse at a polarity switching point and turning ON, OFF a motor at the generating interval of the pulse. CONSTITUTION:A motor pulse P is present at a motor terminal T1 at the time of switching a polarity. The pulse P is output from a connecting point 2 of the terminal T1 and an inductor L, and applied to a pulse detector 3. If the generating interval of the pulses P is increased, a driving control voltage S4 exceeds a threshold value to attain a high level. Since the output SD of a NAND circuit 10 is converted to a low level, a driving transistor Q1 is turned OFF to stop energizing a DC motor M. Accordingly, when the motor M is restricted, it can effectively prevent a restriction current from flowing. Even if the performance of a power source is lowered, this shut-off is effectively performed to reduce heat generation of the circuit, electric energy loss.
