Abstract: PURPOSE:To obtain a titled optical disk which has a high weather resistance and a structure by sticking a protective plate to the surface of a recording layer through an organic material layer which has a high heat resisting property and can absorb a deformation of the surface of the recording layer. CONSTITUTION:An organic material layer 5 which has a high heat resisting property and absorbs a variation of the surface of a recording layer caused by a variation of a pit shape at the time of recording is applied to the surface of a recording layer 2. As for this organic material layer, a silicon compound resin, etc. are applied thinly and uniformly by a spin coating method, etc., and thereafter, after hardening it to some extent by heating, etc., a protective plate 7 made of glass, etc. is stuck to the upper face of the organic material layer 5 by using an adhesive agent 6 such as an ultraviolet hardened resin, etc. and formed as one body. As for an optical disk A constituted in such a way, the protective plate 7 obstructs completely a fact that moisture in the air invades the recording layer 2, therefore, that which has an extremely high weather resistance is obtained.

IPC: B62D5/08
Filed: 1981-04-10
Abstract: PURPOSE:To simplify the construction by forming a fluid pressure thrust bearing, between the input and output shafts of a rotary type power steering device, using the pressure fluid which has finished its work in the rotary control valve and thereby eliminating necessity for use of any mechanical bearings. CONSTITUTION:The input 1 and output 2 shafts are installed in such a way as rotatable with respect to each other by pinching pins 20, 21 projecting from each shaft with a C-shaped spring 22. A recess 23 is formed on the axis side of input shaft 1 except the periphery of the major diameter part 1a, and the space E formed by this recess 23 is fed with the pressure fluid used in the control valve. The oil pressure fed in such a way acts on the recess 23 to bear the thrust force at the input shaft 1. Thus touch of the input shaft 1 with the end face of the output shaft 2 at the time of steering can be prevented.

Title: Method and apparatus for washing substrate, liquid crystal display apparatus and production thereof
Inventor: KUBOTA TAKESHI
IPC: B08B3/02
Filed: 1998-03-06
Abstract: PROBLEM TO BE SOLVED: To obtain uniform washing effect in the vicinity of the central part and outer peripheral part of a substrate at an apparatus cost comparable to that of a conventional substrate washing apparatus. SOLUTION: Three brushes 3a, 3b, 3c attached to an arm 2 at a predetermined interval are scanned a plurality of times along the circular arc locus passing through the center part of a substrate 1 while the substrate 1 is rotated at a predetermined speed. The brush 3a scans the entire range from the center part of the substrate 1 to the outer peripheral part thereof and the brush 3b scans the peripheral range excepting the vicinity of the center part of the substrate 1 and the brush 3C further scans the outer peripheral part further from the brush 3b.  By increasing the number of the brushes scanning the surface of the substrate 1 from the center part of the substrate 1 to the outer peripheral part thereof, the washing time per a unit area of the central part of the substrate 1 becomes almost equal to that of the outer peripheral part thereof and uniform washing effect is obtained on the entire surface of the substrate 1. This constitution can be also adapted to ultrasonic washing ejecting pure water using ultrasonic vibration from a nozzle other than brush washing.

Title: Signal transmission system
Inventor: HONMA EIJIYU
IPC: B60L15/42
Filed: 1982-04-01
Abstract: PURPOSE:To improve the reliability of the whole of a signal transmission system wherein respective stations are looped, by transmitting a message from the (n-1)th station to the (n)th and the (n+1)th stations. CONSTITUTION:In addition to a normal flow M1-M2-M3-M4-M5 of a message, a transmission line provides another flow M1'-M3'-M5'-M2'-M4'. If part of the transmission system, e.g. the 3rd station 3 becomes unable to operate, the 4th station 4 once detecting a failure in receiving a message M3 from a reception part R1 performs such switching that a message M2' is received from the reception part R2.Consequently, an answer message of its station is combined with the message M2' to form a message M4, which is transmitted to the 5th station 5. Therefore, if a fault occurs in a part of the transmission system or a station, messages are transmitted without shutting down the whole system.

IPC: G11B7/126
Filed: 1985-03-22
Abstract: PURPOSE:To obtain a reproduced waveform having good symmetrical properties between the rise and the fall by changing a modulated signal pulse into a proper pulse waveform to control the laser output. CONSTITUTION:The pulses 7a and 7b are produced in response to the front and rear edges of an input modulated signal 5, and a pit or domain is formed with the laser output of a pulse train 6 obtained by giving a time interval 8 between both pulses 7a and 7b. In this case, the interval 8 of the train 6 is increased when the pulse width of the signal 5 is increased. Then the indent 11 of a reproduced signal waveform 10 is increased. Thus the laser output 12 which does not give the effect of the heat dispersion so much is applied to the interval 8. Otherwise it is possible to use a laser output waveform 15 where one or several pulses 16 are put into the interval 8.
