Title: Frequency and intensity stabilizing laser device
Inventor: SUZUKI NORITO
IPC: H01S3/13
Filed: 1985-04-16
Abstract: PURPOSE:To stabilize oscillation frequency and oscillation intensity by utilizing the freedom of the setting of the intensity of an intensity setter and selecting a value close to the maximum value of oscillating beams as a set point. CONSTITUTION:One polarized light in oscillating beams from a gas laser 1 is selected by a polarizer 2, and intensity thereof is detected by a photoelectric detector 3. The intensity signal is transmitted over a first cavity length control system consisting of a preamplifier 5, a gain control amplifier 6, a bias control amplifier 7, a summing amplifier 8 and a temperature regulator 4, thus stabilizing oscillation frequency. On the other hand, oscillation intensity at a single longitudinal mode is set apart from the intensity adjusting point of the first cavity length control system by an intensity setter 13, a difference between the set value and said intensity adjusting point is detected by a comparator 9, and positive-negative or negative-positive constant voltage is generated in response to the positive or negative value of an error. The constant voltage is charged or discharged slowly to linear type integrators 11, 12 through a high resistor 10, and output voltage from an operational amplifier 12 is increased or decreased gradually. The voltage is added to the signal voltage of the first cavity length control system by employing the amplifier 8. Accordingly, both voltage coincide while being brought close to the set value of the setter 13.

Title: Semiconductor laser
Inventor: MAMINE TAKAYOSHI
IPC: H01S5/20
Filed: 1984-04-23
Abstract: PURPOSE:To contrive the stabilization of a junction position and characteristics by inhibiting the increase of threshold current Ith by a method wherein layers with a small amount of impurity doping are provided in the first and second clad layers on the side of contact with an active layer. CONSTITUTION:The first clad layer 2 and the second clad layer 4 with forbidden band widths larger than that of the active layer 3 are provided with low impurity concentration layers 2a and 4a, respectively, on the sides of contact with the active layer 3a, and with high impurity concentration layers 2b and 4b, respectively, on the sides of keeping away from the active layer 3. Reduction in impurity concentration of the parts of the clad layers 2 and 4 in contact with the active layer 3 enables the inhibition of a current path spreading laterally so as to penetrate down to a non-implanted region 6 and the lateral diffusion of implanted carriers, resulting in the reduction in threshold current Ith. Besides, the movement of acceptors and donors caused by the heat during epitaxial growth can be inhibited, thereby stabilizing the junction position or the characteristics. Further, the series resistance and the leakage of carriers to the hetero junction can be reduced, accordingly, the temperature-dependance of threshold current Ith can be dimished.

Title: Spindle in swaging machine
Inventor: YOSHIDA KEIICHIROU
IPC: B21J9/06
Filed: 1978-07-05
Abstract: PURPOSE: To prevent lowering of stiffness and fracture, without causing excessive strain, even in the case of a relatively long spindle, by providing fitting grooves in  the depression rod in the side wall of a cylindrical body parallel to the center line  thereof symmetrically with respect to the diameter at specified intervals in parallel  arrangement.  
     CONSTITUTION: When the work is inserted between dies 20, 20, and a motor is started, the spindle rotates in the direction of arrow 22. Due to this rotation, when the outward curved wall 7a of a backer 7 comes to the position of a hardening roller 12, the backer 7 is deformed by the extent of protrusion of the outward curved wall 7a to push a depression rod 4 in the direction of arrow 23. As a result, the depression rod 4 presses the dies 20 with its inner end. The dies 20, 20 are pressed by the depression rods 4, 4 provided symmetrically with respect to the diameter so as to approach to each other, thereby processing as intended. Therefore, by sequentially changing the inside forms of the dies 20, 20 the work is processed in the appearance corresponding to the inside form of the dies as the process advances, and is taken out from the opposite side of the inserting direction.

IPC: H01M14/00
Filed: 1984-04-25
Abstract: PURPOSE:To achieve high conversion efficiency by once converting the energy of exhaust heat into chemical energy and then directly converting it into electric energy by the same principle as that for fuel cell technique. CONSTITUTION:In a decomposition container 1, the energy of exhaust heat is utilized to endothermicly decompose liquid CH3CHOHCH3 into gaseous CH3COCH3 and H2. The thus produced gaseous CH3COCH3 and H2 are sent into a separator 2 by means of a pump 10. In the separator 2, CH3COCH3 and H2 are separated from each other according to difference in the boiling point and difference in the transmission constant for a gas permeable membrane between these gases before they are sent into a reaction container 3. In the reaction container 3, CH3COCH3 is caused to electrochemically react with H2 to produce CH3 CHOHCH3. And, the work corresponding to the change in free energy produced during reaction is discharged outside the reaction container 3 as electric energy. The thus produced CH3CHOHCH3 is sent into the decomposition container 1 by means of a pump 11, thereby completing the cycle.

Filed: 1983-05-10
Abstract: PURPOSE:To prevent unnecessary evolution of heat by detaining an optical fiber by means of light transmitting members so that even if light leaks from the optical fiber detaining part the leaking light is transmitted through said members. CONSTITUTION:An optical fiber 1 is housed in a protective tube of a plastic or thin metal. A light transmitting member 3 formed of the same material as the material of the optical fiber, for example, various kinds of optical glass in the cse of a YAG laser, and germanium, silicon, ZnSe, AgCl, etc. in the case of a CO2 laser into a cylindrical shape is used. The fiber 1 is held by said members by linear contact therewith and is screwed by a collet chuck 4 by means of a lock screw 5 and a threshold part 4a. When the lock screw 5 is turned, the fiber 1 is held by the chuck 4 and the members 3. The screw 5 and the protective tube 2 are adhered and fixed after the optical fiber is detained. The leaking light is absorbed by the members 3 when the fiber 1 is detained by said members, by which evolution of heat is obviated and the burn of the fibers 1, 6 is considerably decreased.

Abstract: PURPOSE:To easily detect the abnormality of an encoder by detecting the quantities of plural interference light beams which have mutual phase differences based upon diffracted light beams from diffraction gratings, and generating a warning signal according to the detected quantities. CONSTITUTION:Luminous flux from a laser 1 is split 3 into two beams, which are made incident on positions M1 and M2 of a radiation grating 7, and diffracted light beams of specific degrees among respective transmitted diffracted light beams are reflected 8 and 9, superposed on each other by a polarization beam splitter 3, and divided by optical dividers 12a-12c into four; and they are made incident on photodetecting means 14a-14d through polarizing plates 13a-13d. Then, four sine waveform outputs which are 90 deg. out of phase with one another are obtained from the photodetecting means 14a-14d, and amplified 15a-15d to obtain output signals 18a-18d. Those are inputted to comparators 16a-16d and compared with a threshold value VTH; when all the output signals 18a-18d are smaller than the threshold value VTH, an H signal is obtained from an AND circuit 17 and the warning signal is generated 19 according to the H signal. Thus, an accident of the whole system where the encoder is incorporated is precluded.
