Title: Casting method of ti-contg. molten steel
Inventor: SHIBAYAMA TAKAMASA
IPC: B22D1/00
Filed: 1984-01-27
Abstract: PURPOSE:To prevent oxidation of Ti by SiO2 in slag and the decrease in the content of Ti in a Ti-contg. molten steel in casting of said steel via a ladle by adding a TiO2 source into the ladle to adjust the concn. of TiO2 in the slag to a specific rate or above. CONSTITUTION:A TiO2 source such as ilmenite or the like is charged into the slag in a ladle to adjust the concn. of TiO2 therein to >=2%. Oxidation of Ti in the molten steel by SiO2 is prevented even if the concn. of CaO in the slag is not increased and the decrease of Ti in the molten steel is prevented by the low melting slag in this case. The content of Ti is thus maintained nearly invariably in the initial and late period of pouring of the molten steel into a casting mold. The steel ingot consisting of the steel contg. Ti at a specified rate is thus obtd.

Title: Nonvolatile memory
Inventor: TAKESHIMA MASAHIKO
IPC: G06F21/86
Filed: 1987-01-26
Abstract: PURPOSE:To avoid such a trouble where a secrecy protection state is unjustly released due to the nonstandardized power supply voltage, by using the signal sent from a power supply voltage detecting circuit to inhibit the output of the protection information held by a nonvolatile memory element for security. CONSTITUTION:The unjust release of a secrecy protection state due to the application of the nonstandardized voltage is avoided. For instance, a power supply voltage detecting transistor TR21 conducts earlier than a security TR11 set under a writing state when the power supply voltage Vcc is increased higher than the maximum rated level. Then one of both inputs of a logic gate 23 is always kept at 'L' and the output of the gate 23 is set at 'L' regardless of the other input. Thus a switching TR54 is turned off. As a result, the external reading operation of the stored information is inhibited regardless of a written or unwritten state of the TR11 in case the Vcc exceeds the rated level.

Title: Slab type solid state laser device
Inventor: YUASA HIROSHI
IPC: H01S3/093
Filed: 1987-01-26
Abstract: PURPOSE:To prevent distortion from occurring on a wave surface, by interposing a convex lens between a smoothed surface of a laser medium and its excitation surface and suppressing entrance of excited light into laser medium portions covered with holders. CONSTITUTION:A convex lens 18 is interposed between a smoothed surface 12 of a laser medium, whose both ends are supported by holders 14, and an excitation lamp 17 which is disposed to face this smoothed surface 12. Excited light which intends to enter a non-excitation region of the laser medium covered with the supporters 14 is refracted toward an excitation region by the convex lens 18. Thereupon, a temperature difference between the excitation region and the non-excitation region can be made steep so as to narrow a temperature lapse region, and so optical lengths of laser beams can be prevented from varying with positions where the laser beams become incident in the thickness direction of the laser medium. Therefore, distortion can be prevented from occurring on a wave surface.

Title: Detecting circuit for steering angle center for car
Inventor: MIYAMARU YUKIO
IPC: G01B7/00
Filed: 1981-02-03
Abstract: PURPOSE:To increase the measuring accuracy of a steering angle center, by the constitution that an output voltage of a sensor sensing the movement of a steering wheel axis is stored in a delay circuit via a switch means switched through an output of a car speed detecting circuit. CONSTITUTION:A reed switch 13 of a car speed detector 2 is turned on/off at a prescribed distance, causing an increase/decrease of the output level of an inverter 17. The output of the inverter 17 is given to a switch 7 of a detection circuit 1 to turn on/off the switch 7 depending on the output level. When the switch 7 turns on, a voltage of a sensor 5 is picked up at a terminal 12 through the switch 7 and an integration circuit 10. Since the steering angle detected at the sensor 5 is unstable at low speed and stable at high speed, the voltage at the terminal 12 is a voltage almost corresponding to the steering angle center with a time constant determined with the characteristics of the switch 7 and the circuit 10. Thus, the detecting accuracy of the steering angle center can be increased.
