Title: Laser oscillation device
Inventor: TAGA YOSHIHARU
IPC: H01S3/13
Filed: 1996-10-03
Abstract: PROBLEM TO BE SOLVED: To stabilize laser output by constituting a laser oscillation device with a laser head that is set, so that a light axis is directed vertically and a cover for shutting off the laser head from external air, and controlling a temperature so that the temperature inside the cover becomes higher at an upper part than at a lower part. SOLUTION: Laser beams are taken extracted out of a vertically installed laser head 11 vea, for example, mirrors 12 and 13, focusing lenses 14a and 14b, and a spectroscope 15a. A laser oscillation tube of the laser head 11 is covered with a water-cooling pipe and is arranged in a cover 18, thus preventing the effects due to external temperature fluctuations. Also, heaters 19a and 19b are installed near the upper and lower edges of the laser head 11, and the convection of air is suppressed by setting the temperature at an upper side to be higher than that at the lower side, thus stabilizing the temperature in the cover 18 and hence reducing the temperature fluctuations around the laser head 11, preventing distance fluctuation between resonator mirrors, and stabilizing the output for a long time.

Title: Screw extruder
Inventor: HIRUTA MITSUGI
IPC: B29C48/08
Filed: 1996-10-03
Abstract: PROBLEM TO BE SOLVED: To realize the successive production of a high quality product such as a film or the like by a method wherein the soles of extruders are properly divided so as to keep the temperatures of a molten resin to be extruded at optimum. SOLUTION: The functions of a conventional screw extruder are divided into two portions. Concretely, a first extruder 10 carries out the kneading and melting of a raw material at an optimum temperature. A second extruder receives the molten resin produced by the first extruder 10 and extrudes with a large feeding force through an adapter 26 and a T-die 27. In this case, since no high pressure becomes to be applied to a discharge port 10a, no high back pressure develops in a barrel 12, resulting in simplifying the controlling of the temperature in the barrel and consequently allowing to extrude the molten resin having the optimum temperature to the second extruder 20 at all times.  Further, since the second extruder 20 extruder the molten resin just after its receipt through a T-die 27, the molten resin is molded as is under the optimum temperature state, resulting in allowing to efficiently manufacture a high quality product.

Title: Ultrasonic object recognition device
Inventor: WATANABE HIDEYUKI
IPC: G03H3/00
Filed: 1990-10-01
Abstract: PURPOSE:To improve recognition speed by correcting the initial value of address arithmetic circuit in accordance with the temperature change and memorizing reflecting wave data at roughly determined position in a memory. CONSTITUTION:Ultrasonic sound is emitted from an ultrasonic sensor 2 to an object 14 and the reflected sound is received by the sensor 2. The received signal is converted with an A/D converter circuit 5 into digital signal 8 and is memorized in a memory 6 following the address 12 calculated with an address arithmetic circuit. On the other hand, a temperature sensor 13 detects temperature and inputs in an initial value correction means 10. The means 10 does a correction calculation to decrease an initial value 11 when the temperature is high and to increase it when the temperature is low so as to keep it constant. Then the initial value 11 is input in the arithmetic circuit 9, and the address of the reflected sound data in the memory 6 is calculated to output to the memory 6. And the reflected sound data is memorized at a roughly determined position in the memory 6. Therefore, searching of reflected sound data in the memory device is not necessary even in the case of temperature change, and thus the speed of object recognition is improved.
