Title: 1.5 mum wavelength band wavelength-stabilized laser light source
Inventor: FURUYAMA YOSHITO
IPC: H01S3/109
Filed: 1997-11-14
Abstract: PROBLEM TO BE SOLVED: To enable a reference light source used for wavelength multiplexing communications or light wavelength communications to be stabilized by a method, wherein integral components such as a laser diode, a second harmonic generating device, a rubidium absorption cell, and a phase-locked circuit and attachments are modularized to operate. SOLUTION: A laser diode module 10 outputs laser rays of a wavelength of 1.56 μm, corresponding to a current outputted from a current source which is operated under the control of a servo module 40. The laser rays are collected to the one end of an optical fiber 70 at an output lens port and made to impinge on the input lens port of a second harmonic generating module (SHG). A reference light of wavelength 1.56 μm and a second harmonic light of wavelength 0.78 μm are generated. The second harmonic light separated by a separating means is made to impinge on an absorption cell 30 through the intermediary of an output lens port and an optical fiber 80. A rotation adjustment mechanism provided to the input lens port of the SHG module is so controlled as to make an output light maximum. Consequently, the wavelength of the second harmonic light is synchronized and controlled, so as to be equal to the wavelength 0.78 μm of a rubidium absorption cell.

Abstract: PURPOSE:To greatly reduce the occurrence of noise and vibration by a method in which well-grained slags are placed on the lower crushed stone layer and compacted, and after they are set in a short time, the upper crushed stone layer is placed on them and set completely. CONSTITUTION:The lower crushed stone layer 2 of a given thickness is placed on an elevated floor 1, and well-grained slags of a given thickness are placed on the layer 2 and compacted to set them to a desired compressive strength. Afterwards, the upper crushed stone layer 5 of a given thickness is placed on the slag layer 3 and the slag layer 3 is allowed to set completely. As the well-grained slags, ones containing 15-30wt.% fine grains passing 100% through 30mmX30mm sieve and also passing through 80mumX80mum sieve are used. The density of the slag layer 3 can thus be increased and the layer 3 can also be homogenized.

Inventor: YADA HIROSHI
IPC: C09J7/02
Filed: 1998-11-04
Abstract: PROBLEM TO BE SOLVED: To obtain a film which is excellent in weatherability and is almost free of blocking by forming a layer having an ultraviolet-absorbing function in a substrate. SOLUTION: A layer having an ultraviolet-absorbing function is formed, preferably by printing, in a substrate comprising at least one film made preferably of a polyolefin or polyvinyl chloride; that is, this laminated film has a structure wherein a layer having an ultraviolet-absorbing function is sandwiched between substrate materials. A pressure-sensitive adhesive layer is formed on one side of the laminated film, thus giving a surface-protecting pressure-sensitive adhesive sheet, which has a weatherability not degraded by the adhesive and which, when wound into a roll and then unwound, does not cause the ultraviolet- absorbing layer to be removed by the adhesive layer. It is preferable that the laminated film is subjected to a corona treatment when the adhesive layer is formed thereon.

Abstract: PROBLEM TO BE SOLVED: To allow one face recording on a receiver-side through initiative from a transmitter-side by informing a transmitter of the presence or absence of the double face recording function of reception information from a receiver and informing the receiver of the presence or absence of the execution of double face reading and the destination of the execution of one face recording from the transmitter. SOLUTION: A one face recording designation key 32 is a button on a transmitter- side for designating one face recording to a receiver. When the designation key 32 is depressed, a depression pulse is generated in a signal line 32a. A one face recording designation display circuit 34 displays that one face recording is designated to the receiver from the transmitter-side. A control circuit 20 controls whole facsimile equipment. When the designation of one face recording is informed from the transmitter even if double face recording is selected by the receiver, the circuit 20 controls a system to execute the one face recording of reception information. When the operator of the transmitter-side judges that information to be transmitted is difficult to be viewed if the receiver-side executes double face recording, one face recording is designated and it can be informed to the receiver.  Then, the receiver-side can realize one face recording.
