Title: Optical transmission system
Inventor: SHAKE IPPEI
IPC: H04B3/46
Filed: 1999-03-25
Abstract: PROBLEM TO BE SOLVED: To transmit a controlling signal corresponding to an overhead containing the time division multiplex control information or the like by the same wavelength or approximately the same wavelength as that of a main signal. SOLUTION: An optical transmitter 1 extends the optical wave-forms of an OTDM(optical time division multiplexing) signal of wavelength λ0 and a control light signal of wavelength λ1 (≈λ0) in a time region, multiplexes the control light signal whose optical peak intensity is sufficiently reduced as compared with the peak intensity of the OTDM signal and sends the multiplexed light signal to a transmitting optical fiber 3.  An optical receiver 2 branches the transmitted OTDM signal and control light signal into two optical components, outputs one of the signal components to an optical time division demultiplexing means 23, restores the control light signal included in the other optical component to the original optical pulse string, converts the optical pulse string into an electric signal, extracts control information, and provides the extracted information to the means 23.

Title: Engine driven type air conditioner
Inventor: HAYAKAWA SEIJI
IPC: F25B27/02
Filed: 1989-03-30
Abstract: PURPOSE:To simplify the construction for reducing the production cost, and increase the air conditioning capacity with a reduction in the size of air conditioner, by providing radiators, through which cooling water flows both in cooling and heating operation, on a path upstream an outdoor heat exchanger. CONSTITUTION:When a compressor 3 is driven by an engine 4, engine cooling water always passes through radiators 27a and 27b to transfer the waste heat of the engine 4 to outdoor heat exchangers 17a and 17b by convection. As the radiator 27a and 27b are installed upstream the outdoor heat exchangers, dew is hard to form on the outdoor heat exchangers 17a and 17b even when the outdoor temperature becomes very low during heating operation. The condensing pressure of the outdoor heat exchangers 17a and 17b is prevented from becoming too low and the indoor heat exchangers form freezing even when the outdoor temperature becomes very low during cooling operation. Because a solenoid valve becomes unnecessary to be provided, the construction of air conditioner is simplified, and the waste heat of the engine can be stably dissipated.

Abstract: PROBLEM TO BE SOLVED: To obtain a high positional resolution, by using measured values continuously given to a moving stage during moving with a specific measuring system and obtaining prediction values of stage position. SOLUTION: A moving mirror 90 which is irradiated with a laser light from a laser source is put on a wafer stage 40 and the interference of the reflected light of the moving mirror 90 and that from a fixed mirror is measured with an interferometer so that the position of the wafer 81 in Y-axis direction is exactly measured. An interferometer system 38 measures the position of a mask stage 32 at specific time intervals. The measured values are input in a controller 48 to calculate by using a program stored in the controller 48 and very accurate present position of the mask stage 32 is predicted by regression analysis. Also, accurate present position of the wafer stage 40 is calculated using the regression analysis.  To guaranty that the stages are relatively positioned very accurately, the accurate positioning information is used in the controller 48, a mask servo-system 34 and a wafer servo-system 42.

Abstract: PURPOSE:To enable face pressure to be constant between a dynamic slip guide and a slide substance by providing a servo mechanism for adjusting the supply pressure of pressurized oil according to output from a detector for detecting relative inclination between a guide face and a slide face. CONSTITUTION:Servo valves 407 and 108 are being supplied with pressurized oil from a hydraulic source on a predetermined supply pressure Ps. The servo valves 407 and 408 feed pressurized oil to static pressure pockets 313-316 through a throttle in proportion to instruction values from servo amplifiers 409 and 410. When a grinder axis head 101 is free from moment, clearances between the land of a static pressure plate 207 and lower portions. Also, a force generated at said faces 205-206 presses dynamic pressure slide guide faces 201-204. When moment has been applied to the grinder axis head 101, this head 101 inclines and the aforementioned clearances give a change. The servo valve 407 and 408, however, work to apply such moment to the grinder axis head 101 as to correct the inclination thereof and the posture of said head 101 returns to an original position.

Abstract: PURPOSE:To improve heat resistance, by fusing aromatic thermoplastic polyimide material and fixing it. CONSTITUTION:Lead frame pins 2 of a 42 nickel plate are put on a heat plate whose temperature is kept at 220 deg.C. After a thermoplastic polyimide film of 1.5mm in width and 50mum in thickness is put on the pins, the film is irradiated with far infrared rays from a lamp, and heated and fused at about 450 deg.C. Thus the film is fusion-bonded to the lead frame pins 2. After cooling at a room temperature, the 90 deg. bonding strength between the 42 nickel plate lead frame pin 2 and the thermoplastic polyimide film 1 is measured, and the average value of 0.6kg/cm is obtained. Each material maintains excellent appearance, and disturbance of pins can not be recognized. The aromatic thermoplastic polyimide material is buried in the part between the pins, without thickening the upper parts of the lead frame pins, so that strength, gaps, and insulation can be ensured.
