Abstract: PURPOSE:To eliminate pixel deviation on a large screen by disposing oppositely a transparent plate on a synthesizing dichroic mirror and equalizing the numbers of transmission that three color beams of red, green and blue transmit through the transparent plate. CONSTITUTION:In the case of a blue color beam 5, after it transmits through the synthesizing dichroic mirror 13, it transmits through the transparent plate 33, and is reflected by the synthesizing dichroic mirror 17 to be expanded and displayed on the large screen 20 through a projection optical system 19. Then, the blue color beam 5 transmits through the transparent plate twice in all. On the other hand, in the case of a red color beam 10, after it transmits through the transparent plate 33, it is reflected by the synthesizing dichroic mirror 13, and transmits through the transparent plate 33 again and is reflected by the synthesizing dichroic mirror 17, and transmits through the transparent plate twice in all. Similarly, in the case of a green color beam, it transmits through the transparent plate 34 and the synthesizing dichroic mirror 17 twice in all, and the numbers of transmission of three colors are equalized also.

Title: Oil supplying device for linear compressor
Inventor: OH WON SIK
IPC: F04B39/02
Filed: 1999-05-12
Abstract: PROBLEM TO BE SOLVED: To reduce the number of valves related to suction and discharge of oil and make a manufacturing easy by providing a discharge cover on which an oil duct communicated with an oil pocket of a compressor unit is formed and connecting a tip part of this discharge cover with an oil supply case into which an upper side semi-circular part at an opening end is force-fitted. SOLUTION: By energizing a linear motor of a compressor unit 10, a piston is reciprocated, and coolant sucked within a compression chamber of a cylinder is compressed and is discharged from a discharge port. Because an oil supply pipe 110 vibrates in left and right directions integrally with the compressor unit 10 in such a linear compressor, a mass body 120 within the oil supply pipe 110 is inertial-flowed. Oil is sucked into the oil supply pipe 110 by a pressure difference on both sides of the mass body 120 by motion of this mass body 120, oil within the oil supply pipe 110 is discharged to an oil pocket P via a discharge cover 150 and an oil duct 151 and is supplied to friction portions of driving elements.

Title: Filter circuit
Inventor: HORIIKE YOSHIO
IPC: H03H11/04
Filed: 1998-05-14
Abstract: PROBLEM TO BE SOLVED: To provide a stable filter circuit which has no change in its center frequency, by addition or subtraction between the output of an amplifier and an output of a delay means which delays the amplifier output by a prescribed time and feeding the added or subtracted output back to the input of the amplifier so as to have the negative feedback outside a desired band. SOLUTION: The signal that is amplified by an amplifier 13 by 20 dB, for example, is added to the output signal of a delay means 15 by a 1st addition/ subtraction means 14. If the center frequency of a BPF is set to 50 kHz and the delay time of the means 15 is set to 10 μrespectively, the signal of 50 kHz becomes zero by the means 14. The output signal of the means 14 is inputted to a 2nd addition/subtraction means 12 and the subtraction is performed from the signal that is inputted to an input terminal 11. Thereby, the signal of 50 kHz is amplified by 20 dB compared with the signal inputted to the terminal 11 and outputted to an output terminal 17. The output signal of the means 14 has its amplitude increasing gradually and its phase approximates to the same phase of the input signal as the center frequency shifts more from 50 kHz.

With the passage of fluid through a pressure fluid feed inlet 11, a stringlike long-sized object 7 is pulled ahead by means of a drawing mechanism 12, and an inner cylinder advances being accompanied with the stringlike long-sized object. The endless double cylinder moves forward in a lining device as it turns around, and an adhesive agent is also fed forward and comes inbetween the lining device and the pipe-line to adhere together with the two lining material and the pipe-line. After adhering is completed, the endless cylinder and the stringlike long-sized object are removed to obtain a lined pipe-line.

Title: Wireless lamp increasing system
Inventor: HAGIUDA SHINGI
IPC: H05B41/32
Filed: 1980-09-24
Abstract: PURPOSE:To prevent a light emission error of a slave stroboscopic lamp, by emitting the slave stroscopic lamp only when the next photodetecion has been executed in a prescribed period from the first photodetection, and detecting the stand-by light emission of a master stroboscopic lamp and its regular light emission after a prescribed time has elapsed. CONSTITUTION:When a photodetecting element 301 detects the stand-by light emission of a master stroboscopic lamp, an output of an AC amplifier 300 becomes an L level, and is changed to an H level when the light emission is stopped. As a result, the first timer 400 is triggered, the first switching circuit 500 becomes an operating state only for a period T2, and when regular light emission occurs within this period, an H level output is generated by receiving an output signal of the amplifier 300, and SCRs 11' 20' of the light emitting circuit are made conductive. In this way, a slave stroboscopic lamp starts to emit light. The third switching circuit 900 outputs a signal for stopping the light emission of the slave stroboscopic lamp, when the light emission of the master stroboscopic lamp is stopped.
