Abstract: PURPOSE:To reduce transmission loss, by forming the first thin clad layer made of a glass having a m.p. lower than that of the outermost silica glass and the second clad low m.p. glass layer on the first clad layer in a thickness enough to prevent invasion of OH from the outermost layer. CONSTITUTION:In producing an optical fiber especially by the CVD method form the inside, on the inside of the outermost silica glass layer 4, the second clad layer 3 is formed, which is made of low m.p. glass composed of SiO2 as well as B2O3 and P2O5, has the same refractive index as the layer 4 and has the thickness enough to prevent invasion of OH from the layer 4. On the inside of the layer 3, the first thin clad layer 32 is formed, which is made of SiO2 contg. a slight amt. of P2O5, has a m.p. lower than that of the layer 4 but higher than that of the layer 3, and has a refractive index lower than that of the core 1 made of SiO2 contg. GeO2 and higher than the layer 3. The transmitted light oozed out of the core 1 is enclosed in the layer 32 in such a constitution, and prevented from being absorbed by B2O3 in the layer 3 and by the OH groups, too, and the obtained optical fiber has a true circular section, and small transmission loss.

Abstract: PURPOSE:To obtain high picture quality by using an adder, a limiter circuit, a subtractor and a field memory so as to constitute a noise reducer for a chrominance carrier signal thereby improving the S/N by a few memory capacities. CONSTITUTION:An LPF 2 separates a low frequency conversion chrominance carrier signal and the processing such as frequency conversion is applied by a chrominance signal reproducing processing system 4 to form a chrominance carrier signal.

IPC: B23Q3/06
Filed: 1990-06-22
Abstract: PURPOSE:To leave pressure in a hydraulic driving chamber by a check valve and prevent the excessive pressure incresse by allowing a hydraulic driving chamber to communicate to a pressure compensation valve when the pressure at a pressure port is in a normal state, and closing a bypass opening/closing valve in an abnormal pressure lowering state. CONSTITUTION:When the pressure port P of a residual pressure holding valve device 11 is in the normal pressure state, a bypass opening/closing valve 17 is selected to a valve opening position Y, and the hydraulic driving chamber 2 of a hydraulic cylinder 1 communicates to a pressure compensation valve 12 through the bypass opening/closing valve 17. Accordingly, even if the pressure in the hydraulic driving chamber 2 increases at a slow speed by the volume expansion of the pressurized oil by the receiving of heat of the hydraulic cylinder 1, the hydraulic pressure increase portion is discharged to a pressurized oil discharge passage 7 from the pressure compensation valve 12. Accordingly, the excessive increase of the pressure in the hydraulic driving chamber 2 is prevented. Further, when the pressure of the pressure port P lowers abnormally, a bypass valve seat is closeds by a piston valve body by the springy pressure of a residual pressure holding spring 19, and bypass opening/ closing valve 17 is selected to a valve closing position X.

Title: Controlling device for laser oscillation
Inventor: HORIMATSU TETSUO
IPC: H01S5/042
Filed: 1978-12-31
Abstract: PURPOSE: To make the designing easier so as to get excellent operation control by bending the stripe-formed electrode on the surface of a semiconductor element and utilizing as monitor ray the ray coming out from the surface other than that composes the resonator.  
     CONSTITUTION: Stripe-formed electrode 4 is bent on the surface of a semiconductor element SC. Accordingly, faces 2 and 5 construct a resonator of a laser oscillator and face 7 serves as the face from which the monitor ray is taken out. The main signal ray is emitted from spot 6 in the vertical direction to the face 5 composing the resonator, while monitor ray being taken out from spot 8. The monitor ray thus taken out is that not fully cosnfined in the lower part of electrode 4 and enjoys excellent property capable of following the main signal. In addition, though it becomes necessary to increase threshold current a little for starting laser oscillation because the stripe-formed electrode is bent, oscillation mode is stabilized. The relation of the monitor ray with main signal is the same as that in the case when the former is taken out from the face 5, even when it is taken out from the face 9 parallel with the face 5.

Abstract: PURPOSE:To lock a packet with one member by interlocking a lock member to the overstroke of the packet, separating it from a main body and shifting toward the position to lock the packet. CONSTITUTION:When an upper cover 28 is pushed in and a lock pin 52 runs on to a taper part 62, an upper cover 28 and the packet 26 comes to be at the overstroke position, a stopper pin 60 is separated from a main body 24 of a lock lever 50, and thereby, the engaging relation of a stopper pin 60 and a lock lever 50 comes off. When the stopper pin 60 runs on to the recessed part 58 of the lock lever 50, the lock lever 50 receives the turning energizing force in a counter-clockwise direction by a spring 56, the lock pin 52 is abutted and held to a step part 64 of the lock lever 50. In such a condition, when the force added to the upper cover 28 is released, the lock pin 52 is shifted by a spring 29 for return and fitted into a locking groove 66. Thus, since a packet locking mechanism is composed of one locking lever, the construction of the packet locking mechanism come to be simple.
