Title: Method and equipment for laser beam marking, and driving method for liquid crystal element
Inventor: CHIBA TEIICHIRO
IPC: B23K26/00
Filed: 1996-11-29
Abstract: PROBLEM TO BE SOLVED: To improve the efficiency of the marking work by controlling the temperature and the operation to keep a liquid crystal mask at the temperature higher than the room temperature to improve the responsive speed of the liquid crystal in making a work by scanning the laser beam on the liquid crystal mask on which the marking pattern is indicated. SOLUTION: A laser beam oscillator 1 to be used for laser beam marking is also used as a heat source to heat a pattern display region 6 of a liquid crystal mask 4. Only the pattern display region 6 is heated at high temperature by performing the scanning at the prescribed speed with the laser beam with excellent energy concentration as the heat source. A temperature sensor 20 for measuring the temperature of the pattern display region 6 and a cooling fan 21 for cooling the pattern display region are arranged in the vicinity of the liquid crystal mask 4. The detected value of the temperature sensor 20 is inputted by a temperature controller 24 to control the temperature of the pattern display region 6. The responsive speed of the liquid crystal is improved, and the marking pattern switching time is reduced.

Title: Indexing controlling device for tool rest of nc lathe
Inventor: KOJIMA TAKAYOSHI
IPC: B23Q16/02
Filed: 1990-11-22
Abstract: PURPOSE:To perform indexing for a tool rest correctly and stably by setting an output torque of a servo motor at zero when a tool rest clamp condition is checked for every execution of tool rest indexing, and setting its rotation angle for a holding means to be an instruction angle for next instruction for the same tool rest indexing. CONSTITUTION:A tool rest indexing angle instruction memory 5 reads an indexing angle instruction from a tool rest indexing surface recognized by a program interpreting part 2. A sequence control part 3 executes a tool rest unclamp action. In the meanwhile, a tool rest indexing control part 6 rotates a tool rest 12 to a designated angle. When rotation of the tool rest is completed, the sequence control part 3 puts a tool rest clamp instruction on. In addition, at completion of clamping, a torque zero instruction is generated from a torque instruction zero instruction part 8 to a servo motor control part 7. When a servo motor 9 stops generating a torque by the torque zero instruction, an indexing angle is fixed at the tool rest 12 according to a precision of indexing teeth. An actual tool rest indexing angle is written to a tool rest indexing angle instruction memory 5 for setting.

Filed: 1995-12-08
Abstract: PROBLEM TO BE SOLVED: To attain natural 2-way speech by suppressing howling or echo in the case of hand-free speech in telephone speech and avoiding one-way speech. SOLUTION: A microcomputer 16 receives transmission voice amplification data from an A/D converter 15 and multiplex a reference constant with the data. The transmission voice amplification data are given to the microcomputer 16, which provides an output of corresponding PWM control signal to a transmission voice signal level control circuit 19. Furthermore, the result of multiplication is subtracted from the reference constant. The reference constant is selected so that the total gain in the path of a reception voice signal level control circuit 12 and a transmission voice signal level control circuit 19 is the '1' or below. The subtracted PWM control signal is given to reception voice signal level control circuit 12, in which the level is reduced and a resulting reception voice amplification signal is fed to a reception output amplifier 13.

Title: Universal joint
Inventor: SAITO MORIO
IPC: F16L27/06
Filed: 1994-12-26
Abstract: PURPOSE: To prevent the occurrence of serious leakage during the occurrence of a fire and to provide reliable sealing ability in an ordinary working state. CONSTITUTION: A joint sleeve 20 is oscillatorily coupled to a coupling body 10 in a seal state through compression of seal packings 31 and 32. Even when the seal packings 31 and 32 are burnt out during the occurrence of a fire, since a thermal expansion packing 40 mounted in a recessed groove 15 is expanded to embed the outer surface of the protrusion spherical surface 21 of the joint sleeve 20, serious leakage does not occur. Further, since the thermal expansion packing 40 presses the maximum diameter part on a central axis of the protrusion spherical surface 21 toward the central side is moved to one of the right and the left on an axis to prevent the increase of the expansion space of the thermal expansion packing 40, and fire resisting performance by the thermal expansion packing 40 is ensured.  This constitution ensures sealing ability of an oscillating coupling part between the coupling body 10 and the joint sleeve 20, and prevents leakage of fluid, such as city gas, flowing through the coupling.

Title: Treatment of membrane module
Inventor: KAWADA ICHIRO
IPC: B01D65/02
Filed: 1988-12-20
Abstract: PURPOSE:To prevent a decrease in water permeating capacity of a membrane module having the membrane surface treated with aq. formaldehyde soln. in the stage of resumption of operation by treating the membrane surface with alkalized alcohol. CONSTITUTION:A membrane module is allowed to contact with aq. formaldehyde soln. in order to prevent propagation of harmful bacteria when the operation of membrane module is suspended for a relatively long time, but the water permeation capacity of the membrane decreases when the operation is resumed. In this case, if the membrane is treated with alkaline alcohol, the initial water permeation capacity can be maintained. Suitable alcohol is ethanol, or methanol, and suitable alkali is NaOH, hydrazine, ammonia, etc. A process for adjusting the property of the alcohol to alkaline property, is to add an alkaline material to the alcohol having 10-100% concn. to adjust thus the pH to 9-12. This method is effective for aromatic polyamide type reverse osmotic membranes.
